Kids with concussions may benefit from early return to school
The timing for return to school after a concussion has been the subject of guidelines, but data on how the timing of school returns affects later symptom burdens are limited, Christopher G. Vaughan, PhD, of Children’s National Hospital, Rockville, Md., and colleagues wrote.
Examining how the timing of return to school (RTS) affects later symptoms is needed to inform early postinjury management, they said.
In the new study published in JAMA Network Open, the researchers identified 1,630 children and teens aged 5-18 years who were treated for concussions at nine Canadian pediatric EDs. The primary outcome was symptom burden at 14 days post concussion, based on the Post-Concussion Symptom Inventory (PCSI). Early RTS was defined as missing fewer than 3 days of school post concussion.
Overall, the mean number of missed school days was 3.74 (excluding weekends). When divided by age, the mean number of missed days was 2.61 for children aged 5-7 years, 3.26 for those aged 8-12 years, and 4.71 for those aged 13-18 years.
Slightly more than half (53.7%) of the participants had an early RTS of 2 missed days or fewer. Later RTS was most common in the oldest age group, followed by the middle and younger age groups.
The researchers used a propensity score–matched analysis to determine associations. At 14 days, an early RTS was associated with reduced symptoms among 8- to 12-year-olds and 13- to 18-year-olds, though not in the youngest patients aged 5-7 years. In addition, the researchers created quantiles based on initial symptom ratings.
For the youngest age group, the association between early RTS and reduced symptoms at day 14 was higher among those with lower initial symptoms.
For the two older groups, the association was higher for those with higher initial symptoms (based on the PCSI).
The findings that earlier RTS was associated with a lower symptom burden at day 14 for those with higher levels of symptoms at baseline was surprising, but the mechanisms of the timing and effect of RTS requires more study, the researchers wrote in their discussion.
The effect of early RTS on symptoms may be in part related to factors such as “the benefits of socialization, reduced stress from not missing too much school, maintaining or returning to a normal sleep-wake schedule, and returning to light to moderate physical activity (gym class and recreational activities),” the researchers noted.
Another study related to recovery and concussion recently appeared in Neurology. In that study, the authors found that those athletes who took a longer time to recover from a sports-related concussion could still return to play with additional time off, but the methods and populations differed from the current study, which focused on RTS rather than returning to play.
The current study findings were limited by several factors including the lack of randomization for RTS timing and a lack of data on the variety of potential supports and accommodations students received, the researchers noted.
However, the results were strengthened by the large size and diverse nature of the concussions, and the roughly equal representation of boys and girls, they said.
Although randomized trials are needed to determine the best timing for RTS, the current study suggests that RTS within 2 days of a concussion is associated with improved symptoms, “and may directly or indirectly promote faster recovery,” they concluded.
Early return remains feasible for most children and teens
“Return to school can be a complicated issue for children and teens with concussions,” said Caitlyn Mooney, MD, a pediatrician and specialist in sports medicine at the University of Texas Health Science Center, San Antonio, said in an interview. Although much research has focused on diagnosis and return to sport after a concussion, there has been less focus on returning to school and learning. Various issues post concussion can make schooling difficult, and students may experience trouble with vision, concentration, sleep, headaches, and more.
Despite this knowledge, studies that specifically address recommended school protocols are limited, Dr. Mooney said. “Additionally, all concussions are different; while some students will need minimal help to return and succeed in school, others may need individualized learning plans and accommodations for school.” A return to school ideally would be a team-based approach with input from the parent, patient, physician, and educators.
“The theory of cognitive rest stems from the idea that a concussion causes metabolic dysfunction in the brain, and that increasing the metabolic demands of the brain can result in symptoms and a delayed return to school,” said Dr. Mooney.
Evidence suggests that those who start resting early after a concussion improve more quickly, “but there has been ongoing discussion over the years of what is the correct balance of cognitive rest to returning to modified activity,” she said. “This has led to the current general recommendation of rest for 24-48 hours followed by a gradual return to school as tolerated.”
Although the current study is large, it is limited by the lack of randomization, Dr. Mooney noted, therefore conclusions cannot be made that the cause of the improved symptoms is a quicker return to school.
However, the results support data from previous studies, in that both of the older age groups showed less disease burden at 14 days after an earlier return to school, she said.
“With prolonged absences, adolescents get isolated at home away from friends, and they may have increased mood symptoms. Additionally, I have found a high number of my patients who do not go to school as quickly have more sleep disturbance, which seems to increase symptoms such as difficulty concentrating or headaches,” she said. “It seems like the students do benefit from a routine schedule even if they have to have some accommodations at school, especially older students who may have more stress about missing school and falling behind on schoolwork.”
The message for pediatricians is that return to school should be individualized, Dr. Mooney said.
Although the current study does not dictate the optimal return to school, the results support those of previous studies in showing that, after 1-2 days of rest, an early return does not harm children and teens and may improve symptoms in many cases, she said. “In my experience, sometimes schools find it easier to keep the student at home rather than manage rest or special accommodations,” but the current study suggests that delaying return to school may not be the right choice for many patients.
“I hope this study empowers clinicians to advocate for these students, that the right place for them is in the classroom even with rest, extra time, or other accommodations,” said Dr. Mooney.
“Each concussion should be evaluated and treated individually; there will likely be a few who may need to stay home for a longer period of time, but this study suggests that the majority of students will suffer no ill effects from returning to the normal routine after a 2-day rest,” she noted.
The study was supported by the Canadian Institutes for Health Research. Dr. Vaughan and several coauthors disclosed being authors of the Postconcussion Symptom Inventory outside of the current study. Dr. Mooney had no financial conflicts to disclose.

Social isolation hikes dementia risk in older adults
, new research suggests. Results from a longitudinal study that included more than 5,000 United States–based seniors showed that nearly one-quarter were socially isolated.
After adjusting for demographic and health factors, social isolation was found to be associated with a 28% higher risk for developing dementia over a 9-year period, compared with non-isolation. In addition, this finding held true regardless of race or ethnicity.
“Social connections are increasingly understood as a critical factor for the health of individuals as they age,” senior study author Thomas K.M. Cudjoe, MD, Robert and Jane Meyerhoff Endowed Professor and assistant professor of medicine, Division of Geriatric Medicine and Gerontology, Johns Hopkins University School of Medicine, Baltimore, said in a press release. “Our study expands our understanding of the deleterious impact of social isolation on one’s risk for dementia over time,” Dr. Cudjoe added.
The findings were published online in the Journal of the American Geriatric Society.
Upstream resources, downstream outcomes
Social isolation is a “multidimensional construct” characterized by factors such as social connections, social support, resource sharing, and relationship strain. It also affects approximately a quarter of older adults, the investigators noted.
Although prior studies have pointed to an association between socially isolated older adults and increased risk for incident dementia, no study has described this longitudinal association in a nationally representative cohort of U.S. seniors.
Dr. Cudjoe said he was motivated to conduct the current study because he wondered whether or not older adults throughout the United States were similar to some of his patients “who might be at risk for worse cognitive outcomes because they lacked social contact with friends, family, or neighbors.”
The study was also “informed by conceptual foundation that upstream social and personal resources are linked to downstream health outcomes, including cognitive health and function,” the researchers added.
They turned to 2011-2020 data from the National Health and Aging Trends Study, a nationally representative, longitudinal cohort of U.S. Medicare beneficiaries. The sample was drawn from the Medicare enrollment file and incorporated 95 counties and 655 zip codes.
Participants (n = 5,022; mean age, 76.4 years; 57.2% women; 71.7% White, non-Hispanic; 42.4% having more than a college education) were community-dwelling older adults who completed annual 2-hour interviews that included assessment of function, economic health status, and well-being. To be included, they had to attend at least the baseline and first follow-up visits.
NHATS “includes domains that are relevant for the characterization of social isolation,” the investigators wrote. It used a typology of structural social isolation that is informed by the Berkman-Syme Social Network Index.
Included domains were living arrangements, discussion networks, and participation. All are “clinically relevant, practical, and components of a comprehensive social history,” the researchers noted.
They added that individuals classified as “socially isolated” often live alone, have no one or only one person that they can rely upon to discuss important matters, and have limited or no engagement in social or religious groups.
Social isolation in the study was characterized using questions about living with at least one other person, talking to two or more other people about “important matters” in the past year, attending religious services in the past month, and participating in the past month in such things as clubs, meetings, group activities, or volunteer work.
Wake-up call
Study participants received 1 point for each item/domain, with a sum score of 0 or 1 classified as “socially isolated” and 2 or more points considered “not socially isolated.” They were classified as having probable dementia based either on self-report or lower-than-mean performance in 2 or more cognitive domains, or a score indicating probable dementia on the AD8 Dementia Screening Interview.
Covariates included demographic factors, education, and health factors. Mean follow-up was 5.1 years.
Results showed close to one-quarter (23.3%) of the study population was classified as socially isolated, with one-fifth (21.1%) developing dementia by the end of the follow-up period.
Compared with non-isolated older adults, those who were socially isolated were more likely to develop dementia during the follow-up period (19.6% vs. 25.9%, respectively).
After adjusting for demographic factors, social isolation was significantly associated with a higher risk for incident dementia (hazard ratio, 1.33; 95% confidence interval, 1.13-1.56). This association persisted after further adjustment for health factors (HR, 1.27; 95% CI, 1.08-1.49). Race and ethnicity had no bearing on the association.
In addition to the association between social isolation and dementia, the researchers also estimated the cause-specific hazard of death before dementia and found that, overall, 18% of participants died prior to dementia over the follow-up period. In particular, the social isolation–associated cause-specific HR of death before dementia was 1.28 (95% CI, 1.2-1.5).
Dr. Cudjoe noted that the mechanism behind the association between social isolation and dementia in this population needs further study. Still, he hopes that the findings will “serve as a wake-up call for all of us to be more thoughtful of the role of social connections on our cognitive health.”
Clinicians “should be thinking about and assessing the presence or absence of social connections in their patients,” Dr. Cudjoe added.
‘Instrumental role’
Commenting on the study, Nicole Purcell, DO, neurologist and senior director of clinical practice at the Alzheimer’s Association, said the study “contributes to the growing body of evidence that finds social isolation is a serious public health risk for many seniors living in the United States, increasing their risk for dementia and other serious mental conditions.”
Dr. Purcell, who was not involved with the study, added that “health care systems and medical professionals can play an instrumental role in identifying individuals at risk for social isolation.”
She noted that for those experiencing social isolation, “interaction with health care providers may be one of the few opportunities those individuals have for social engagement, [so] using these interactions to identify individuals at risk for social isolation and referring them to local resources and groups that promote engagement, well-being, and access to senior services may help decrease dementia risk for vulnerable seniors.”
Dr. Purcell added that the Alzheimer’s Association offers early-stage programs throughout the country, including support groups, education, art, music, and other socially engaging activities.
The study was funded by the National Institute on Aging, National Institute on Minority Health and Health Disparities, and Secunda Family Foundation. The investigators and Dr. Purcell have reported no relevant financial relationships.

Participants (n = 5,022; mean age, 76.4 years; 57.2% women; 71.7% White, non-Hispanic; 42.4% having more than a college education) were community-dwelling older adults who completed annual 2-hour interviews that included assessment of function, economic health status, and well-being. To be included, they had to attend at least the baseline and first follow-up visits.
NHATS “includes domains that are relevant for the characterization of social isolation,” the investigators wrote. It used a typology of structural social isolation that is informed by the Berkman-Syme Social Network Index.
Included domains were living arrangements, discussion networks, and participation. All are “clinically relevant, practical, and components of a comprehensive social history,” the researchers noted.
They added that individuals classified as “socially isolated” often live alone, have no one or only one person that they can rely upon to discuss important matters, and have limited or no engagement in social or religious groups.
Social isolation in the study was characterized using questions about living with at least one other person, talking to two or more other people about “important matters” in the past year, attending religious services in the past month, and participating in the past month in such things as clubs, meetings, group activities, or volunteer work.
Wake-up call
Study participants received 1 point for each item/domain, with a sum score of 0 or 1 classified as “socially isolated” and 2 or more points considered “not socially isolated.” They were classified as having probable dementia based either on self-report or lower-than-mean performance in 2 or more cognitive domains, or a score indicating probable dementia on the AD8 Dementia Screening Interview.
Covariates included demographic factors, education, and health factors. Mean follow-up was 5.1 years.
Results showed close to one-quarter (23.3%) of the study population was classified as socially isolated, with one-fifth (21.1%) developing dementia by the end of the follow-up period.
Compared with non-isolated older adults, those who were socially isolated were more likely to develop dementia during the follow-up period (19.6% vs. 25.9%, respectively).
After adjusting for demographic factors, social isolation was significantly associated with a higher risk for incident dementia (hazard ratio, 1.33; 95% confidence interval, 1.13-1.56). This association persisted after further adjustment for health factors (HR, 1.27; 95% CI, 1.08-1.49). Race and ethnicity had no bearing on the association.
In addition to the association between social isolation and dementia, the researchers also estimated the cause-specific hazard of death before dementia and found that, overall, 18% of participants died prior to dementia over the follow-up period. In particular, the social isolation–associated cause-specific HR of death before dementia was 1.28 (95% CI, 1.2-1.5).
Dr. Cudjoe noted that the mechanism behind the association between social isolation and dementia in this population needs further study. Still, he hopes that the findings will “serve as a wake-up call for all of us to be more thoughtful of the role of social connections on our cognitive health.”
Clinicians “should be thinking about and assessing the presence or absence of social connections in their patients,” Dr. Cudjoe added.
‘Instrumental role’
Commenting on the study, Nicole Purcell, DO, neurologist and senior director of clinical practice at the Alzheimer’s Association, said the study “contributes to the growing body of evidence that finds social isolation is a serious public health risk for many seniors living in the United States, increasing their risk for dementia and other serious mental conditions.”
Dr. Purcell, who was not involved with the study, added that “health care systems and medical professionals can play an instrumental role in identifying individuals at risk for social isolation.”
She noted that for those experiencing social isolation, “interaction with health care providers may be one of the few opportunities those individuals have for social engagement, [so] using these interactions to identify individuals at risk for social isolation and referring them to local resources and groups that promote engagement, well-being, and access to senior services may help decrease dementia risk for vulnerable seniors.”
Dr. Purcell added that the Alzheimer’s Association offers early-stage programs throughout the country, including support groups, education, art, music, and other socially engaging activities.
The study was funded by the National Institute on Aging, National Institute on Minority Health and Health Disparities, and Secunda Family Foundation. The investigators and Dr. Purcell have reported no relevant financial relationships.

Physician sues AMA for defamation over 2022 election controversy
If Willarda Edwards, MD, MBA, had won her 2022 campaign for president-elect of the American Medical Association (AMA), she would have been the second Black woman to head the group.
The lawsuit sheds light on the power dynamics of a politically potent organization that has more than 271,000 members and holds assets of $1.2 billion. The AMA president is one of the most visible figures in American medicine.
“The AMA impugned Dr. Edwards with these false charges, which destroyed her candidacy and irreparably damaged her reputation,” according to the complaint, which was filed Nov. 9, 2022, in Baltimore County Circuit Court. The case was later moved to federal court.
The AMA “previously rejected our attempt to resolve this matter without litigation,” Dr. Edwards’ attorney, Timothy Maloney, told this news organization. An AMA spokesman said the organization had no comment on Dr. Edwards’ suit.
Dr. Edwards is a past president of the National Medical Association, MedChi, the Baltimore City Medical Society, the Monumental City Medical Society, and the Sickle Cell Disease Association of America. She joined the AMA in 1994 and has served as a trustee since 2016.
As chair of the AMA Task Force on Health Equity, “she helped lead the way in consensus building and driving action that in 2019 resulted in the AMA House of Delegates establishing the AMA Center on Health Equity,” according to her AMA bio page.
‘Quid pro quo’ alleged
In June 2022, Dr. Edwards was one of three individuals running to be AMA president-elect.
According to Dr. Edwards’ complaint, she was “incorrectly advised by colleagues” that Virginia urologist William Reha, MD, had decided not to seek the AMA vice-speakership in 2023. This was important because both Dr. Edwards and Dr. Reha were in the Southeastern delegation. It could be in Dr. Edwards’ favor if Dr. Reha was not running, as it would mean one less leadership candidate from the same region.
Dr. Edwards called Dr. Reha on June 6 to discuss the matter. When they talked, Dr. Reha allegedly recorded the call without Dr. Edwards’ knowledge or permission – a felony in Maryland – and also steered her toward discussions about how his decision could benefit her campaign, according to the complaint.
The suit alleges that Dr. Reha’s questions were “clearly calculated to draw some statements by Dr. Edwards that he could use later to thwart her candidacy and to benefit her opponent.”
On June 10, at the AMA’s House of Delegates meeting in Chicago, Dr. Edwards was taken aside and questioned by members of the AMA’s Election Campaign Committee, according to the complaint. They accused her of “vote trading” but did not provide any evidence or a copy of a complaint they said had been filed against her, the suit said.
Dr. Edwards was given no opportunity to produce her own evidence or rebut the accusations, the suit alleges.
Just before the delegates started formal business on June 13, House Speaker Bruce Scott, MD, read a statement to the assembly saying that a complaint of a possible campaign violation had been filed against Dr. Edwards.
Dr. Scott told the delegates that “committee members interviewed the complainant and multiple other individuals said to have knowledge of the circumstances. In addition to conducting multiple interviews, the committee reviewed evidence that was deemed credible and corroborated that a campaign violation did in fact occur,” according to the complaint.
The supposed violation: A “quid pro quo” in which an unnamed delegation would support Dr. Edwards’ current candidacy, and the Southeastern delegation would support a future candidate from that other unnamed delegation.
Dr. Edwards was given a short opportunity to speak, in which she denied any violations.
According to a news report, Dr. Edwards said, “I’ve been in the House of Delegates for 30 years, and you know me as a process person – a person who truly believes in the process and trying to follow the complexities of our election campaign.”
The lawsuit alleges that “this defamatory conduct was repeated the next day to more than 600 delegates just minutes prior to the casting of votes, when Dr Scott repeated these allegations.”
Dr. Edwards lost the election.
AMA: Nothing more to add
The suit alleges that neither the Election Campaign Committee nor the AMA itself has made any accusers or complaints available to Dr. Edwards and that it has not provided any audio or written evidence of her alleged violation.
In July, the AMA’s Southeastern delegation told its membership, “We continue to maintain that Willarda was ‘set up’ ... The whole affair lacked any reasonable semblance of due process.”
The delegation has filed a counter claim against the AMA seeking “to address this lack of due process as well as the reputational harm” to the delegation.
The AMA said that it has nothing it can produce. “The Speaker of the House presented a verbal report to the attending delegates,” said a spokesman. “The Speaker’s report remains the only remarks from an AMA officer, and no additional remarks can be expected at this time.”
He added that there “is no official transcript of the Speaker’s report.”

Will your smartphone be the next doctor’s office?
A fingertip pressed against a phone’s camera lens can measure a heart rate. The microphone, kept by the bedside, can screen for sleep apnea. Even the speaker is being tapped, to monitor breathing using sonar technology.
In the best of this new world, the data is conveyed remotely to a medical professional for the convenience and comfort of the patient or, in some cases, to support a clinician without the need for costly hardware.
But using smartphones as diagnostic tools is a work in progress, experts say. Although doctors and their patients have found some real-world success in deploying the phone as a medical device, the overall potential remains unfulfilled and uncertain.
Smartphones come packed with sensors capable of monitoring a patient’s vital signs. They can help assess people for concussions, watch for atrial fibrillation, and conduct mental health wellness checks, to name the uses of a few nascent applications.
Companies and researchers eager to find medical applications for smartphone technology are tapping into modern phones’ built-in cameras and light sensors; microphones; accelerometers, which detect body movements; gyroscopes; and even speakers. The apps then use artificial intelligence software to analyze the collected sights and sounds to create an easy connection between patients and physicians. Earning potential and marketability are evidenced by the more than 350,000 digital health products available in app stores, according to a Grand View Research report.
“It’s very hard to put devices into the patient home or in the hospital, but everybody is just walking around with a cellphone that has a network connection,” said Dr. Andrew Gostine, CEO of the sensor network company Artisight. Most Americans own a smartphone, including more than 60% of people 65 and over, an increase from just 13% a decade ago, according the Pew Research Center. The COVID-19 pandemic has also pushed people to become more comfortable with virtual care.
Some of these products have sought FDA clearance to be marketed as a medical device. That way, if patients must pay to use the software, health insurers are more likely to cover at least part of the cost. Other products are designated as exempt from this regulatory process, placed in the same clinical classification as a Band-Aid. But how the agency handles AI and machine learning–based medical devices is still being adjusted to reflect software’s adaptive nature.
Ensuring accuracy and clinical validation is crucial to securing buy-in from health care providers. And many tools still need fine-tuning, said Eugene Yang, MD, a professor of medicine at the University of Washington, Seattle. Currently, Dr. Yang is testing contactless measurement of blood pressure, heart rate, and oxygen saturation gleaned remotely via Zoom camera footage of a patient’s face.
Judging these new technologies is difficult because they rely on algorithms built by machine learning and artificial intelligence to collect data, rather than the physical tools typically used in hospitals. So researchers cannot “compare apples to apples” with medical industry standards, Dr. Yang said. Failure to build in such assurances undermines the technology’s ultimate goals of easing costs and access because a doctor still must verify results.
“False positives and false negatives lead to more testing and more cost to the health care system,” he said.
Big tech companies like Google have heavily invested in researching this kind of technology, catering to clinicians and in-home caregivers, as well as consumers. Currently, in the Google Fit app, users can check their heart rate by placing their finger on the rear-facing camera lens or track their breathing rate using the front-facing camera.
“If you took the sensor out of the phone and out of a clinical device, they are probably the same thing,” said Shwetak Patel, director of health technologies at Google and a professor of electrical and computer engineering at the University of Washington.
Google’s research uses machine learning and computer vision, a field within AI based on information from visual inputs like videos or images. So instead of using a blood pressure cuff, for example, the algorithm can interpret slight visual changes to the body that serve as proxies and biosignals for a patient’s blood pressure, Mr. Patel said.
Google is also investigating the effectiveness of the built-in microphone for detecting heartbeats and murmurs and using the camera to preserve eyesight by screening for diabetic eye disease, according to information the company published last year.
The tech giant recently purchased Sound Life Sciences, a Seattle startup with an FDA-cleared sonar technology app. It uses a smart device’s speaker to bounce inaudible pulses off a patient’s body to identify movement and monitor breathing.
Binah.ai, based in Israel, is another company using the smartphone camera to calculate vital signs. Its software looks at the region around the eyes, where the skin is a bit thinner, and analyzes the light reflecting off blood vessels back to the lens. The company is wrapping up a U.S. clinical trial and marketing its wellness app directly to insurers and other health companies, said company spokesperson Mona Popilian-Yona.
The applications even reach into disciplines such as optometry and mental health:
- With the microphone, Canary Speech uses the same underlying technology as Amazon’s Alexa to analyze patients’ voices for mental health conditions. The software can integrate with telemedicine appointments and allow clinicians to screen for anxiety and depression using a library of vocal biomarkers and predictive analytics, said Henry O’Connell, the company’s CEO.
- Australia-based ResApp Health last year for its iPhone app that screens for moderate to severe obstructive sleep apnea by listening to breathing and snoring. SleepCheckRx, which will require a prescription, is minimally invasive compared with sleep studies currently used to diagnose sleep apnea. Those can cost thousands of dollars and require an array of tests.
- Brightlamp’s Reflex app is a clinical decision support tool for helping manage concussions and vision rehabilitation, among other things. Using an iPad’s or iPhone’s camera, the mobile app measures how a person’s pupils react to changes in light. Through machine learning analysis, the imagery gives practitioners data points for evaluating patients. Brightlamp sells directly to health care providers and is being used in more than 230 clinics. Clinicians pay a $400 standard annual fee per account, which is currently not covered by insurance. The Department of Defense has an ongoing clinical trial using Reflex.
In some cases, such as with the Reflex app, the data is processed directly on the phone – rather than in the cloud, Brightlamp CEO Kurtis Sluss said. By processing everything on the device, the app avoids running into privacy issues, as streaming data elsewhere requires patient consent.
But algorithms need to be trained and tested by collecting reams of data, and that is an ongoing process.
Researchers, for example, have found that some computer vision applications, like heart rate or blood pressure monitoring, can be less accurate for darker skin. Studies are underway to find better solutions.
Small algorithm glitches can also produce false alarms and frighten patients enough to keep widespread adoption out of reach. For example, Apple’s new car-crash detection feature, available on both the latest iPhone and Apple Watch, was set off when people were riding roller coasters and automatically dialed 911.
“We’re not there yet,” Dr. Yang said. “That’s the bottom line.”

Earning potential and marketability are evidenced by the more than 350,000 digital health products available in app stores, according to a Grand View Research report.
“It’s very hard to put devices into the patient home or in the hospital, but everybody is just walking around with a cellphone that has a network connection,” said Dr. Andrew Gostine, CEO of the sensor network company Artisight. Most Americans own a smartphone, including more than 60% of people 65 and over, an increase from just 13% a decade ago, according the Pew Research Center. The COVID-19 pandemic has also pushed people to become more comfortable with virtual care.
Some of these products have sought FDA clearance to be marketed as a medical device. That way, if patients must pay to use the software, health insurers are more likely to cover at least part of the cost. Other products are designated as exempt from this regulatory process, placed in the same clinical classification as a Band-Aid. But how the agency handles AI and machine learning–based medical devices is still being adjusted to reflect software’s adaptive nature.
Ensuring accuracy and clinical validation is crucial to securing buy-in from health care providers. And many tools still need fine-tuning, said Eugene Yang, MD, a professor of medicine at the University of Washington, Seattle. Currently, Dr. Yang is testing contactless measurement of blood pressure, heart rate, and oxygen saturation gleaned remotely via Zoom camera footage of a patient’s face.
Judging these new technologies is difficult because they rely on algorithms built by machine learning and artificial intelligence to collect data, rather than the physical tools typically used in hospitals. So researchers cannot “compare apples to apples” with medical industry standards, Dr. Yang said. Failure to build in such assurances undermines the technology’s ultimate goals of easing costs and access because a doctor still must verify results.
“False positives and false negatives lead to more testing and more cost to the health care system,” he said.
Big tech companies like Google have heavily invested in researching this kind of technology, catering to clinicians and in-home caregivers, as well as consumers. Currently, in the Google Fit app, users can check their heart rate by placing their finger on the rear-facing camera lens or track their breathing rate using the front-facing camera.
“If you took the sensor out of the phone and out of a clinical device, they are probably the same thing,” said Shwetak Patel, director of health technologies at Google and a professor of electrical and computer engineering at the University of Washington.
Google’s research uses machine learning and computer vision, a field within AI based on information from visual inputs like videos or images. So instead of using a blood pressure cuff, for example, the algorithm can interpret slight visual changes to the body that serve as proxies and biosignals for a patient’s blood pressure, Mr. Patel said.
Google is also investigating the effectiveness of the built-in microphone for detecting heartbeats and murmurs and using the camera to preserve eyesight by screening for diabetic eye disease, according to information the company published last year.
The tech giant recently purchased Sound Life Sciences, a Seattle startup with an FDA-cleared sonar technology app. It uses a smart device’s speaker to bounce inaudible pulses off a patient’s body to identify movement and monitor breathing.
Binah.ai, based in Israel, is another company using the smartphone camera to calculate vital signs. Its software looks at the region around the eyes, where the skin is a bit thinner, and analyzes the light reflecting off blood vessels back to the lens. The company is wrapping up a U.S. clinical trial and marketing its wellness app directly to insurers and other health companies, said company spokesperson Mona Popilian-Yona.
The applications even reach into disciplines such as optometry and mental health:
- With the microphone, Canary Speech uses the same underlying technology as Amazon’s Alexa to analyze patients’ voices for mental health conditions. The software can integrate with telemedicine appointments and allow clinicians to screen for anxiety and depression using a library of vocal biomarkers and predictive analytics, said Henry O’Connell, the company’s CEO.
- Australia-based ResApp Health last year for its iPhone app that screens for moderate to severe obstructive sleep apnea by listening to breathing and snoring. SleepCheckRx, which will require a prescription, is minimally invasive compared with sleep studies currently used to diagnose sleep apnea. Those can cost thousands of dollars and require an array of tests.
- Brightlamp’s Reflex app is a clinical decision support tool for helping manage concussions and vision rehabilitation, among other things. Using an iPad’s or iPhone’s camera, the mobile app measures how a person’s pupils react to changes in light. Through machine learning analysis, the imagery gives practitioners data points for evaluating patients. Brightlamp sells directly to health care providers and is being used in more than 230 clinics. Clinicians pay a $400 standard annual fee per account, which is currently not covered by insurance. The Department of Defense has an ongoing clinical trial using Reflex.
In some cases, such as with the Reflex app, the data is processed directly on the phone – rather than in the cloud, Brightlamp CEO Kurtis Sluss said. By processing everything on the device, the app avoids running into privacy issues, as streaming data elsewhere requires patient consent.
But algorithms need to be trained and tested by collecting reams of data, and that is an ongoing process.
Researchers, for example, have found that some computer vision applications, like heart rate or blood pressure monitoring, can be less accurate for darker skin. Studies are underway to find better solutions.
Small algorithm glitches can also produce false alarms and frighten patients enough to keep widespread adoption out of reach. For example, Apple’s new car-crash detection feature, available on both the latest iPhone and Apple Watch, was set off when people were riding roller coasters and automatically dialed 911.
“We’re not there yet,” Dr. Yang said. “That’s the bottom line.”

Brain differences suggest therapeutic targets in Takotsubo
A new study has identified differences in the brain present in patients with the cardiac disorder Takotsubo syndrome versus control scans, which may lead to new therapeutic targets.
Takotsubo syndrome is an acute heart failure cardiomyopathy mimicking an acute myocardial infarction in its presentation, but on investigation, no obstructive coronary disease is present. The syndrome, which mainly affects women, typically occurs in the aftermath of intense emotional or physical stress and has become known as “broken heart syndrome.”
The mechanism by which emotional processing in the context of stress leads to significant cardiac injury and acute left ventricular dysfunction is not understood. So, the current study examined both structural and functional effects in the brain in patients with Takotsubo syndrome to shed more light on the issue.
“The abnormalities in the thalamus-amygdala-insula and basal ganglia support the concept of involvement of higher-level function centers in Takotsubo syndrome, and interventions aimed at modulating these may be of benefit,” the authors conclude.
The study was published online in JACC: Heart Failure.
Lead author Hilal Khan, MB BCh, BAO, from the University of Aberdeen (Scotland), explained to this news organization that patients with Takotsubo syndrome have a substantial drop in heart function and show an apical ballooning of the heart.
It is a relatively newly defined condition and was first described in 1990 in Japan, and so named because the heart was thought to resemble the Takotsubo pot used by Japanese fishermen to trap octopus.
Although uncommon, the condition is not rare. Dr. Khan estimates that about 1 in 20 women with suspected MI turn out to have Takotsubo syndrome, with cases increasing in times of global stress such as in the recent pandemic.
While patients tend to recover in a few weeks and the pumping function of the heart usually returns to normal, there are some long-term cardiac complications including a reduction in global longitudinal strain, and patients have similar long-term outcomes as those with MI.
“It is believed that these cardiac changes may be triggered by changes in the brain caused by emotional stress, so we wanted to look at this more closely,” Dr. Khan said.
There have been a couple of studies published previously looking at brain changes in Takotsubo syndrome, but they haven’t reported patients in the acute stage of the condition and they haven’t compared the patients to controls, he noted.
For the current study, the researchers looked at brain scans for 25 acute Takotsubo patients and in 25 controls matched for age, gender, comorbidities, and medications. All the patients and controls were examined using the same MRI scanner in the same hospital.
“This is the largest structural and functional brain study of acute Takotsubo syndrome patients compared with matched control subjects,” Dr. Khan said.
The researchers looked at many different factors including brain volume in different regions, cortical thickness, small-vessel disease, and functional and structural connectivity to try and obtain a complete holistic view of the brain.
Key findings were that patients with Takotsubo syndrome had smaller brain volumes, compared with matched controls, driven by a reduction in brain surface area. In contrast, the insula and thalamus regions were larger.
“A reduction in brain volume could be caused by inflammation; this is often seen in depression,” Dr. Khan commented.
The researchers also found that certain areas of the brain had a reduction in functional connectivity, particularly the thalamus – the central autonomic area of the brain, which regulates the autonomic nervous system – and also the insula region, which is also involved in the autonomic regulation of the heart.
They suggest that there may be a loss of parasympathetic inhibition in Takotsubo syndrome, which would fit the theory that Takotsubo brings with it a surge of catecholamines, which could injure the heart.
Reduced functional connectivity was also seen in parts of the basal ganglia, abnormalities of which have been associated with an increased risk of both arrhythmias, and in the amygdala, similar to patients with a tendency to catastrophize events.
The other observation was that there appeared to be an increase in structural connectivity in certain areas of the brain.
“Structural pathways seem to be increased but functional connectivity was reduced, so while physical pathways are enhanced, they don’t seem to be doing anything,” Dr. Khan said. “We don’t know why this occurs, or if this has happened over time and made the brain and heart more vulnerable in some way.”
One possibility is that ,under a significant emotional stress, the brain may divert function from some areas to others to be able to cope, and that this results in reduced functioning in areas of the brain responsible for regulating the heart, Dr. Khan suggested.
“We believe this study confirms that the brain is involved in Takotsubo syndrome, and we have identified markers in the brain that may be contributing to the condition,” he said.
The researchers are planning to further study these markers and whether it might be possible to modulate these changes with various interventions such as exercise or mindfulness.
“We believe there is some interface between the brain changes and the impact on the heart. We don’t think it is just the release of catecholamines that causes damage to the heart. We think there is something else happening as well,” Dr. Khan commented.
It is also possible that the hearts of patients with Takotsubo syndrome are predisposed in some way and more vulnerable to this condition occurring.
“It will be important to obtain a greater understanding of the triggers and identify people who may be vulnerable,” Dr. Khan noted. “Around 10% of individuals who experience Takotsubo syndrome will have a recurrence, so we need to try and develop preventative strategies to reduce this.”
He suggested that possible preventive or therapeutic approaches may involve interventions such as exercise or mindfulness.

FROM JACC: HEART FAILURE
It’s all about the brains: Guilt placebos, transplants, and negative feelings
Guilt reduction, now in deceptive and open-secret forms
Guilt plagues a lot of us, sometimes regularly. Maybe you felt bad about eating the leftovers that your partner was looking forward to eating at the end of the day. Or for not saving a seat for your friend who was running late to the movies. Maybe even hiding a secret that you know would hurt a person’s feelings. We’ve all felt it, and it doesn’t feel good.
But what if there was a pill that would make those feelings seem to hurt less? There’s already a pill for almost everything, right?
Well, researchers from the University of Basel are on the case and have conducted a study suggesting that a placebo might work. They asked participants to write down a time they felt super guilty about something, just to stir up those feelings again, then they were divided into three groups. One group was told they would receive real medication that was actually a placebo, one was told they would get a placebo, and one got nothing. The subjects’ guilty feelings were reduced in both the medication-that-was-really-a-placebo group and placebo-that-was-a-placebo group.
“Our study therefore supports the intriguing finding that placebos work even when they are administered openly, and that explanation of the treatment is key to its effectiveness,” lead author Dilan Sezer said in a written statement.
More research is needed, but the human mind is a very interesting place. It seems like we can convince ourselves of just about anything. Especially to feel less guilty.
It’s a mad, mad, mad, mad scientist’s world
Mad scientists. Life’s just more interesting with a few of them running around, but they’re mostly relegated to works of fiction. Real life is boring; we don’t actually have neurosurgeons going around claiming human brain transplant is technically feasible.
Best of all, this isn’t even Dr. Sergio Canavero’s first rodeo with mad science: In 2015 he claimed human head transplants were technically feasible, and in the past few years has claimed to have rehearsed head transplants on cadavers and successfully repaired spinal cord injuries in animals. Lots of claims in there, but precious little evidence. And contrary to what everyone at the head enhancement clinic says, people will notice if you start going around with a new head.
But let’s get back to brains. Ignoring the fact that brain transplant sounds like a zombie with a PhD nibbling on your skull, the article does appear in a peer-reviewed journal. So surely there’s some level of legitimacy. After all, it’s not like Dr. Canavero is an editor for this journal. [Editor’s note: By that we mean he is an editor for the journal.]
Man, he’s taking all the fun out of this.
Anyway, now that we’ve prefaced this with the mother of all caveats, what exactly is Dr. Canavero proposing with his brain transplant? It’s pretty simple: Just have a robot scoop out the first brain and place it into a fresh body, either a donated but moribund younger body or a cloned body. Reconnect all the nerves and vasculature and you’re good to go. Enjoy your wine and laugh in the face of death.
Naturally, such a … bold proposal is lacking in the details, but who cares about details, anyway? This is mad science, not respectable science. Professionals have standards. And if we hear that a human brain transplant was successfully completed on a non–dark and stormy night and the doctor didn’t cackle madly “It’s alive! It’s alive!” then honestly, what even was the point?
Ambivalence rules!
As the office’s unofficial Sith lord/Star Wars nerd, LOTME takes notice when science extols the benefits of unhappiness: “It’s good to be grumpy: Bad moods make us more detail-oriented, study shows.”
The investigators manipulated the emotions of participants by having them watch a clip from “Sophie’s Choice” or one from “Friends.” Then the subjects listened to short, emotionally neutral stories, some of which contained inconsistencies, with the text displayed on a computer screen. Sorry to say, gang at Central Perk, but round one went to the sad movie.
“When people are in a negative mood, they are more careful and analytical. They scrutinize what’s actually stated in a text, and they don’t just fall back on their default world knowledge,” lead author Vicky Lai, PhD, of the University of Arizona said in a statement from the school.
Negative mood. Careful and analytical. Grumpy is good.
You’ve fallen into Darth Science’s little trap, and we have you now.
A study conducted at the University of Geneva offers a slightly different conclusion. And by slightly different, we mean completely different. People over age 65 who watched a series of short TV clips depicting people in a state of emotional suffering experienced excessive modification of their neuronal connections, compared with those who watched emotionally neutral videos.
The brains of these subjects remained “frozen in a negative state by relating the suffering of others to their own emotional memories,” lead author Sebastian Baez Lugo said in a written release from the university.
Emotional suffering. Frozen brains. Grumpy is … not good?
So there you have it. Darth Science’s lesson for the day: A negative mood makes you careful and analytical, but negative thoughts are bad for your brain.

Best of all, this isn’t even Dr. Sergio Canavero’s first rodeo with mad science: In 2015 he claimed human head transplants were technically feasible, and in the past few years has claimed to have rehearsed head transplants on cadavers and successfully repaired spinal cord injuries in animals. Lots of claims in there, but precious little evidence. And contrary to what everyone at the head enhancement clinic says, people will notice if you start going around with a new head.
But let’s get back to brains. Ignoring the fact that brain transplant sounds like a zombie with a PhD nibbling on your skull, the article does appear in a peer-reviewed journal. So surely there’s some level of legitimacy. After all, it’s not like Dr. Canavero is an editor for this journal. [Editor’s note: By that we mean he is an editor for the journal.]
Man, he’s taking all the fun out of this.
Anyway, now that we’ve prefaced this with the mother of all caveats, what exactly is Dr. Canavero proposing with his brain transplant? It’s pretty simple: Just have a robot scoop out the first brain and place it into a fresh body, either a donated but moribund younger body or a cloned body. Reconnect all the nerves and vasculature and you’re good to go. Enjoy your wine and laugh in the face of death.
Naturally, such a … bold proposal is lacking in the details, but who cares about details, anyway? This is mad science, not respectable science. Professionals have standards. And if we hear that a human brain transplant was successfully completed on a non–dark and stormy night and the doctor didn’t cackle madly “It’s alive! It’s alive!” then honestly, what even was the point?
Ambivalence rules!
As the office’s unofficial Sith lord/Star Wars nerd, LOTME takes notice when science extols the benefits of unhappiness: “It’s good to be grumpy: Bad moods make us more detail-oriented, study shows.”
The investigators manipulated the emotions of participants by having them watch a clip from “Sophie’s Choice” or one from “Friends.” Then the subjects listened to short, emotionally neutral stories, some of which contained inconsistencies, with the text displayed on a computer screen. Sorry to say, gang at Central Perk, but round one went to the sad movie.
“When people are in a negative mood, they are more careful and analytical. They scrutinize what’s actually stated in a text, and they don’t just fall back on their default world knowledge,” lead author Vicky Lai, PhD, of the University of Arizona said in a statement from the school.
Negative mood. Careful and analytical. Grumpy is good.
You’ve fallen into Darth Science’s little trap, and we have you now.
A study conducted at the University of Geneva offers a slightly different conclusion. And by slightly different, we mean completely different. People over age 65 who watched a series of short TV clips depicting people in a state of emotional suffering experienced excessive modification of their neuronal connections, compared with those who watched emotionally neutral videos.
The brains of these subjects remained “frozen in a negative state by relating the suffering of others to their own emotional memories,” lead author Sebastian Baez Lugo said in a written release from the university.
Emotional suffering. Frozen brains. Grumpy is … not good?
So there you have it. Darth Science’s lesson for the day: A negative mood makes you careful and analytical, but negative thoughts are bad for your brain.
How to talk with patients in ways that help them feel heard and understood
How do we become those professionals and make sure that we are doing a good job connecting and communicating with our patients?
Here are a few suggestions on how to do this.
Practice intent listening
When a patient shares their symptoms with you, show genuine curiosity and concern. Ask clarifying questions. Ask how the symptom or problem is affecting their day-to-day life. Avoid quick, rapid-fire questions back at the patient. Do not accept a patient self-diagnosis.
When a patient with a first-time headache says they are having a migraine headache, for example, ask many clarifying questions to make sure you can make a diagnosis of headache type, then use all the information you have gathered to educate the patient on what you believe they have.
It is easy to jump to treatment, but we always want to make sure we have the diagnosis correct first. By intently listening, it also makes it much easier to tell a patient you do not know what is causing their symptoms, but that you and the patient will be vigilant for any future clues that may lead to a diagnosis.
Use terminology that patients understand
Rachael Gotlieb, MD, and colleagues published an excellent study with eye-opening results on common phrases we use as health care providers and how often patients do not understand them.
Only 9% of patients understood what was meant when they were asked if they have been febrile. Only 2% understood what was meant by “I am concerned the patient has an occult infection.” Only 21% understood that “your xray findings were quite impressive” was bad news.
It is easy to avoid these medical language traps, we just have to check our doctor speak. Ask, “Do you have a fever?” Say, “I am concerned you may have an infection that is hard to find.”
Several other terms we use all the time in explaining things to patients that I have found most patients do not understand are the terms bilateral, systemic, and significant. Think carefully as you explain things to patients and check back to have them repeat to you what they think you said.
Be comfortable saying you don’t know
Many symptoms in medicine end up not being diagnosable. When a patient shares symptoms that do not fit a pattern of a disease, it is important to share with them why you think it is okay to wait and watch, even if you do not have a diagnosis.
Patients find it comforting that you are so honest with them. Doing this also has the benefit of gaining patients’ trust when you are sure about something, because it tells them you don’t have an answer for everything.
Ask your patients what they think is causing their symptoms
This way, you know what their big fear is. You can address what they are worried about, even if it isn’t something you are considering.
Patients are often fearful of a disease a close friend or relative has, so when they get new symptoms, they fear diseases that we might not think of. By knowing what they are fearful of, you can reassure when appropriate.

Renowned stroke expert Ralph L. Sacco, MD, dies
Ralph L. Sacco, MD, the first neurologist to serve as president of the American Heart Association and the only physician to serve as president of both the AHA and the American Academy of Neurology, died Jan. 17 at the age of 65.
He died of a brain tumor at his home in Amagansett, N.Y., according to an obituary published in Neurology, Circulation, and Stroke.
“Ralph was one of a kind,” Nancy Brown, chief executive officer for the AHA and American Stroke Association, said in a statement. “His leadership was unparalleled, and his warm, generous heart and care transcended his research and clinic to every person fortunate to meet him and likely become a friend,” Ms. Brown said.
In a tweet, Natalia S. Rost, MD, professor of neurology at Harvard Medical School, Boston, called him, “a dear friend, an inspiring colleague, a generous mentor, an astute scientist, a consummate advocate for brain health worldwide.”
Dedicated to improving stroke care
Dr. Sacco was chair of the University of Miami Miller School of Medicine in the department of neurology; the Olemberg Family Chair in Neurological Disorders; professor of neurology, public health sciences, human genetics, and neurosurgery; executive director of the Evelyn F. McKnight Brain Institute; director and multi-principal investigator of the Miami Clinical and Translational Science Institute; and senior associate dean for clinical and translational science.
Dr. Sacco was a population-based researcher in the field of cerebrovascular diseases.
As founder of the Northern Manhattan Study, he paved the way for examining the differences in stroke risk related to race, ethnicity, sex, and neighborhood, and realizing the impact of modifiable lifestyle behaviors, such as alcohol consumption and physical activity, on stroke risk.
Dr. Sacco’s work led to more targeted stroke prevention programs and his “drive and dedication fueled changes that improved stroke research and fostered the development of targeted stroke care delivery, ultimately improving stroke recovery and post-stroke quality of life for many,” the AHA statement said.
Dr. Sacco was also founder and executive director of the Florida Stroke Registry, which consists of 167 Florida stroke centers. He was a member of the National Academy of Medicine.
In an obituary written by Orly Avitzur, MD, current president of the AAN, she notes that he “was the only physician to have become both the president of the AHA (2010-2011) and the AAN (2017-2019), positions that reflected the respect and admiration of professional colleagues earned over the years.”
During his tenure as AAN president, Dr. Sacco led an initiative to ensure that academic neurology, from department chairs to professors to students, knew about the abundance of academy resources available to them, the AAN noted in a statement.
Dr. Sacco was a “strong proponent of enlarging the neurology workforce through the academic pipeline and promoted the concept of the ‘newrologist’ to get people excited in careers in neurology, moving beyond just diagnosis and treatments to include interventions, preventative care, and the future of regenerative care,” the AAN said.
Dr. Sacco received numerous awards throughout his career, most recently the AHA 2022 Distinguished Scientist award. He also received the 2015 Gold Heart Award, the 2011 Distinguished National Leadership Award, and the 2006 William Feinberg Award.
In addition to his husband, Scott Dutcher, Dr. Sacco is survived by his father, Anthony P. Sacco, and his father’s wife, Rosemary; and his four siblings and their families, along with many nieces and nephews.

Adverse events reported in one-quarter of inpatient admissions
as indicated from data from 2,809 admissions at 11 hospitals.
The 1991 Harvard Medical Practice Study, which focused on medical injury and litigation, documented an adverse event rate of 3.7 events per 100 admissions; 28% of those events were attributed to negligence, write David W. Bates, MD, of Brigham and Women’s Hospital, Boston, and colleagues.
Although patient safety has changed significantly since 1991, documenting improvements has been challenging, the researchers say. Several reports have shown a decrease in health care–associated infections. However, other aspects of safety – notably, adverse drug events, defined as injuries resulting from drugs taken – are not easily measured and tracked, the researchers say.
“We have not had good estimates of how much harm is being caused by care in hospitals in an ongoing way that looked across all types of adverse events,” and the current review is therefore important, Dr. Bates said in an interview.
In a study recently published in the New England Journal of Medicine, the researchers analyzed a random sample of 2,809 hospital admissions from 11 hospitals in Massachusetts during the 2018 calendar year. The hospitals ranged in size from fewer than 100 beds to more than 700 beds; all patients were aged 18 years and older. A panel of nine nurses reviewed the admissions records to identify potential adverse events, and eight physicians reviewed the adverse event summaries and either agreed or disagreed with the adverse event type. The severity of each event was ranked using a general severity scale into categories of significant, serious, life-threatening, or fatal.
Overall, at least one adverse event was identified in 23.6% of the hospital admissions. A total of 978 adverse events were deemed to have occurred during the index admission, and 222 of these (22.7%) were deemed preventable. Among the preventable adverse events, 19.7% were classified as serious, 3.3% as life-threatening, and 0.5% as fatal.
A total of 523 admissions (18.6%) involved at least one significant adverse event, defined as an event that caused unnecessary harm but from which recovery was rapid. A total of 211 admissions involved a serious adverse event, defined as harm resulting in substantial intervention or prolonged recovery; 34 included at least one life-threatening event; and seven admissions involved a fatal adverse event.
A total of 191 admissions involved at least one adverse event deemed preventable. Of those, 29 involved at least one preventable adverse event that was serious, life-threatening, or fatal, the researchers write. Of the seven deaths in the study population, one was deemed preventable.
The most common adverse events were adverse drug events, which accounted for 39.0% of the adverse events; surgical or other procedural events accounted for 30.4%; patient care events (including falls and pressure ulcers) accounted for 15.0%; and health care–associated infections accounted for 11.9%.
Overcoming barriers to better safety
“The overall level of harm, with nearly 1 in 4 patients suffering an adverse event, was higher than I expected it might be,” Dr. Bates told this news organization. However, techniques for identifying adverse events have improved, and “it is easier to find them in electronic records than in paper records,” he noted.
“Hospitals have many issues they are currently dealing with since COVID, and one issue is simply prioritization,” Dr. Bates said. “But it is now possible to measure harm for all patients using electronic tools, and if hospitals know how much harm they are having in specific areas, they can make choices about which ones to focus on.”
“We now have effective prevention strategies for most of the main kinds of harm,” he said. Generally, rates of harm are high because these strategies are not being used effectively, he said. “In addition, there are new tools that can be used – for example, to identify patients who are decompensating earlier,” he noted.
As for additional research, some specific types of harm that have been resistant to interventions, such as pressure ulcers, deserve more attention, said Dr. Bates. “In addition, diagnostic errors appear to cause a great deal of harm, but we don’t yet have good strategies for preventing these,” he said.
The study findings were limited by several factors, including the use of data from hospitals that might not represent hospitals at large and by the inclusion mainly of patients with private insurance, the researchers write. Other limitations include the likelihood that some adverse events were missed and the level of agreement on adverse events between adjudicators was only fair.
However, the findings serve as a reminder to health care professionals of the need for continued attention to improving patient safety, and measuring adverse events remains a critical part of guiding these improvements, the researchers conclude.
Timely reassessment and opportunities to improve
In the decades since the publication of the report, “To Err Is Human,” by the National Academies in 2000, significant attention has been paid to improving patient safety during hospitalizations, and health care systems have increased in both system and disease complexity, Said Suman Pal, MBBS, a specialist in hospital medicine at the University of New Mexico, Albuquerque, said in an interview. “Therefore, this study is important in reassessing the safety of inpatient care at the current time,” he said.
“The findings of this study showing preventable adverse events in approximately 7% of all admissions; while concerning, is not surprising, as it is consistent with other studies over time, as the authors have also noted in their discussion,” said Dr. Pal. The current findings “underscore the importance of continuous quality improvement efforts to increase the safety of patient care for hospitalized patients,” he noted.
“The increasing complexity of medical care, fragmentation of health care, structural inequities of health systems, and more recent widespread public health challenges such as the COVID-19 pandemic have been, in my opinion, barriers to improving patient safety,” Dr. Pal said. “The use of innovation and an interdisciplinary approach to patient safety and quality improvement in hospital-based care, such as the use of machine learning to monitor trends and predict the individualized risk of harm, could be a potential way out” to help reduce barriers and improve safety, he said.
“Additional research is needed to understand the key drivers of preventable harm for hospitalized patients in the United States,” said Dr. Pal. “When planning for change, keen attention must be paid to understanding how these [drivers] may differ for patients who have been historically marginalized or are otherwise underserved so as to not exacerbate health care inequities,” he added.
The study was funded by the Controlled Risk Insurance Company and the Risk Management Foundation of the Harvard Medical Institutions. Dr. Bates owns stock options with AESOP, Clew, FeelBetter, Guided Clinical Solutions, MDClone, and ValeraHealth and has grants/contracts from IBM Watson and EarlySense. He has also served as a consultant for CDI Negev. Dr. Pal has disclosed no relevant financial relationships.

The current findings “underscore the importance of continuous quality improvement efforts to increase the safety of patient care for hospitalized patients,” he noted.
“The increasing complexity of medical care, fragmentation of health care, structural inequities of health systems, and more recent widespread public health challenges such as the COVID-19 pandemic have been, in my opinion, barriers to improving patient safety,” Dr. Pal said. “The use of innovation and an interdisciplinary approach to patient safety and quality improvement in hospital-based care, such as the use of machine learning to monitor trends and predict the individualized risk of harm, could be a potential way out” to help reduce barriers and improve safety, he said.
“Additional research is needed to understand the key drivers of preventable harm for hospitalized patients in the United States,” said Dr. Pal. “When planning for change, keen attention must be paid to understanding how these [drivers] may differ for patients who have been historically marginalized or are otherwise underserved so as to not exacerbate health care inequities,” he added.

as indicated from data from 2,809 admissions at 11 hospitals.
The 1991 Harvard Medical Practice Study, which focused on medical injury and litigation, documented an adverse event rate of 3.7 events per 100 admissions; 28% of those events were attributed to negligence, write David W. Bates, MD, of Brigham and Women’s Hospital, Boston, and colleagues.
Although patient safety has changed significantly since 1991, documenting improvements has been challenging, the researchers say. Several reports have shown a decrease in health care–associated infections. However, other aspects of safety – notably, adverse drug events, defined as injuries resulting from drugs taken – are not easily measured and tracked, the researchers say.
“We have not had good estimates of how much harm is being caused by care in hospitals in an ongoing way that looked across all types of adverse events,” and the current review is therefore important, Dr. Bates said in an interview.
In a study recently published in the New England Journal of Medicine, the researchers analyzed a random sample of 2,809 hospital admissions from 11 hospitals in Massachusetts during the 2018 calendar year. The hospitals ranged in size from fewer than 100 beds to more than 700 beds; all patients were aged 18 years and older. A panel of nine nurses reviewed the admissions records to identify potential adverse events, and eight physicians reviewed the adverse event summaries and either agreed or disagreed with the adverse event type. The severity of each event was ranked using a general severity scale into categories of significant, serious, life-threatening, or fatal.
Overall, at least one adverse event was identified in 23.6% of the hospital admissions. A total of 978 adverse events were deemed to have occurred during the index admission, and 222 of these (22.7%) were deemed preventable. Among the preventable adverse events, 19.7% were classified as serious, 3.3% as life-threatening, and 0.5% as fatal.
A total of 523 admissions (18.6%) involved at least one significant adverse event, defined as an event that caused unnecessary harm but from which recovery was rapid. A total of 211 admissions involved a serious adverse event, defined as harm resulting in substantial intervention or prolonged recovery; 34 included at least one life-threatening event; and seven admissions involved a fatal adverse event.
A total of 191 admissions involved at least one adverse event deemed preventable. Of those, 29 involved at least one preventable adverse event that was serious, life-threatening, or fatal, the researchers write. Of the seven deaths in the study population, one was deemed preventable.
The most common adverse events were adverse drug events, which accounted for 39.0% of the adverse events; surgical or other procedural events accounted for 30.4%; patient care events (including falls and pressure ulcers) accounted for 15.0%; and health care–associated infections accounted for 11.9%.
Overcoming barriers to better safety
“The overall level of harm, with nearly 1 in 4 patients suffering an adverse event, was higher than I expected it might be,” Dr. Bates told this news organization. However, techniques for identifying adverse events have improved, and “it is easier to find them in electronic records than in paper records,” he noted.
“Hospitals have many issues they are currently dealing with since COVID, and one issue is simply prioritization,” Dr. Bates said. “But it is now possible to measure harm for all patients using electronic tools, and if hospitals know how much harm they are having in specific areas, they can make choices about which ones to focus on.”
“We now have effective prevention strategies for most of the main kinds of harm,” he said. Generally, rates of harm are high because these strategies are not being used effectively, he said. “In addition, there are new tools that can be used – for example, to identify patients who are decompensating earlier,” he noted.
As for additional research, some specific types of harm that have been resistant to interventions, such as pressure ulcers, deserve more attention, said Dr. Bates. “In addition, diagnostic errors appear to cause a great deal of harm, but we don’t yet have good strategies for preventing these,” he said.
The study findings were limited by several factors, including the use of data from hospitals that might not represent hospitals at large and by the inclusion mainly of patients with private insurance, the researchers write. Other limitations include the likelihood that some adverse events were missed and the level of agreement on adverse events between adjudicators was only fair.
However, the findings serve as a reminder to health care professionals of the need for continued attention to improving patient safety, and measuring adverse events remains a critical part of guiding these improvements, the researchers conclude.
Timely reassessment and opportunities to improve
In the decades since the publication of the report, “To Err Is Human,” by the National Academies in 2000, significant attention has been paid to improving patient safety during hospitalizations, and health care systems have increased in both system and disease complexity, Said Suman Pal, MBBS, a specialist in hospital medicine at the University of New Mexico, Albuquerque, said in an interview. “Therefore, this study is important in reassessing the safety of inpatient care at the current time,” he said.

HRT may prevent Alzheimer’s in high-risk women
new research suggests.
Results from a cohort study of almost 1,200 women showed that use of HRT was associated with higher delayed memory scores and larger entorhinal and hippocampal brain volumes – areas that are affected early by Alzheimer’s disease (AD) pathology.
HRT was also found to be most effective, as seen by larger hippocampal volume, when introduced during early perimenopause.
“Clinicians are very much aware of the susceptibility of women to cognitive disturbances during menopause,” lead author Rasha Saleh, MD, senior research associate, University of East Anglia (England), said in an interview.
“Identifying the at-risk APOE4 women and early HRT introduction can be of benefit. Confirming our findings in a clinical trial would be the next step forward,” Dr. Saleh said.
The findings were published online in Alzheimer’s Research and Therapy.
Personalized approaches
Dr. Saleh noted that estrogen receptors are localized in various areas of the brain, including cognition-related areas. Estrogen regulates such things as neuroinflammatory status, glucose utilization, and lipid metabolism.
“The decline of estrogen during menopause can lead to disturbance in these functions, which can accelerate AD-related pathology,” she said.
HRT during the menopausal transition and afterward is “being considered as a strategy to mitigate cognitive decline,” the investigators wrote. Early observational studies have suggested that oral estrogen “may be protective against dementia,” but results of clinical trials have been inconsistent, and some have even shown “harmful effects.”
The current researchers were “interested in the personalized approaches in the prevention of AD,” Dr. Saleh said. Preclinical and pilot data from her group have shown that women with APOE4 have “better cognitive test scores with nutritional and hormonal interventions.”
This led Dr. Saleh to hypothesize that HRT would be of more cognitive benefit for those with versus without APOE4, particularly when introduced early during the menopausal transition.
To investigate this hypothesis, the researchers analyzed baseline data from participants in the European Prevention of Alzheimer’s Dementia (EPAD) cohort. This project was initiated in 2015 with the aim of developing longitudinal models over the entire course of AD prior to dementia clinical diagnosis.
Participants were recruited from 10 European countries. All were required to be at least 50 years old, to have not been diagnosed with dementia at baseline, and to have no medical or psychiatric illness that could potentially exclude them from further research.
The current study included 1,178 women (mean age, 65.1 years), who were divided by genotype into non-APOE4 and APOE4 groups. HRT treatment for current or previous users included estrogen alone or estrogen plus progestogens via oral or transdermal administration routes, and at different doses.
The four tests used to assess cognition were the Mini-Mental State Examination dot counting to evaluate verbal working memory, the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) total score, the Four Mountain Test, and the supermarket trolley virtual reality test.
Brain MRI data were collected. The researchers focused on the medial temporal lobe as the “main brain region regulating cognition and memory processing.” This lobe includes the hippocampus, the parahippocampus, the entorhinal cortex, and the amygdala.
‘Critical window’
The researchers found a “trend” toward an APOE-HRT interaction (P-interaction = .097) for the total RBANS score. In particular, it was significant for the RBANS delayed memory index, where scores were consistently higher for women with APOE4 who had received HRT, compared with all other groups (P-interaction = .009).
Within-genotype group comparisons showed that HRT users had a higher RBANS total scale score and delayed memory index (P = .045 and P = .002, respectively), but only among APOE4 carriers. Effect size analyses showed a large effect of HRT use on the Four Mountain Test score and the supermarket trolley virtual reality test score (Cohen’s d = 0.988 and 1.2, respectively).
“This large effect was found only in APOE4 carriers,” the investigators noted.
Similarly, a moderate to large effect of HRT on the left entorhinal volume was observed in APOE4 carriers (Cohen’s d = 0.63).
In members of the APOE4 group who received HRT, the left entorhinal and left and right amygdala volumes were larger, compared with both no-APOE4 and non-HRT users (P-interaction = .002, .003, and .005, respectively). Similar trends were observed for the right entorhinal volume (P = .074).
In addition, among HRT users, the left entorhinal volume was larger (P = .03); the right and left anterior cingulate gyrus volumes were smaller (P = .003 and .062, respectively); and the left superior frontal gyrus volume was larger (P = .009) in comparison with women who did not receive HRT, independently of their APOE genotype.
Early use of HRT among APOE4 carriers was associated with larger right and left hippocampal volume (P = .035 and P = .028, respectively) – an association not found in non-APOE4 carriers. The association was also not significant when participants were not stratified by APOE genotype.
“The key important point here is the timing, or the ‘critical window,’ when HRT can be of most benefit,” Dr. Saleh said. “This is most beneficial when introduced early, before the neuropathology becomes irreversible.”
Study limitations include its cross-sectional design, which precludes the establishment of a causal relationship, and the fact that information regarding the type and dose of estrogen was not available for all participants.
HRT is not without risk, Dr. Saleh noted. She recommended that clinicians “carry out various screening tests to make sure that a woman is eligible for HRT and not at risk of hypercoagulability, for instance.”
Risk-benefit ratio
In a comment, Howard Fillit, MD, cofounder and chief science officer at the Alzheimer’s Drug Discovery Foundation, called the study “exactly the kind of work that needs to be done.”
Dr. Fillit, who was not involved with the current research, is a clinical professor of geriatric medicine, palliative care medicine, and neuroscience at Mount Sinai Hospital, New York.
He compared the process with that of osteoporosis. “We know that if women are treated [with HRT] at the time of the menopause, you can prevent the rapid bone loss that occurs with rapid estrogen loss. But if you wait 5, 10 years out, once the bone loss has occurred, the HRT doesn’t really have any impact on osteoporosis risk because the horse is already out of the barn,” he said.
Although HRT carries risks, “they can clearly be managed; and if it’s proven that estrogen or hormone replacement around the time of the menopause can be protective [against AD], the risk-benefit ratio of HRT could be in favor of treatment,” Dr. Fillit added.
The study was conducted as part of the Medical Research Council NuBrain Consortium. The investigators and Dr. Fillit reported no relevant financial relationships.
