A new federal rule could force hospitals and doctors’ groups to boost health cybersecurity measures to better protect patients’ health information and prevent ransomware attacks. Some of the proposed requirements could be expensive for healthcare providers.

The proposed rule, issued by the US Department of Health & Human Services (HHS) and published on January 6 in the Federal Register, marks the first time in a decade that the federal government has updated regulations governing the security of private health information (PHI) that’s kept or shared online. Comments on the rule are due on March 6.

Because the risks for cyberattacks have increased exponentially, “there is a greater need to invest than ever before in both people and technologies to secure patient information,” Adam Greene, an attorney at Davis Wright Tremaine in Washington, DC, who advises healthcare clients on cybersecurity, said in an interview.

Bad actors continue to evolve and are often far ahead of their targets, added Mark Fox, privacy and research compliance officer for the American College of Cardiology.

In the proposed rule, HHS noted that breaches have risen by more than 50% since 2020. Damages from health data breaches are more expensive than in any other sector, averaging $10 million per incident, said HHS.

The damage can continue for years, as much of the data — such as date of birth — in PHI are “immutable,” unlike a credit card number, the agency said. A review of breach reports made to HHS’ Office for Civil Rights shows near-daily data breaches affecting hundreds to tens of thousands of patients. Since December 1 alone, healthcare providers reported breaches affecting nearly 3 million US patients, according to federal data.

Debi Carr, a Florida-based cybersecurity consultant for small physician and dental practices, welcomed the new proposal. “Many practices are clinging to doing things the way they have always done it, and hackers are taking full advantage of that mindset,” she said in an interview. “We have to change our mindset.”

Among the proposal’s recommendations:

• A shift away from making security specifications “addressable” to required. Fox said that many interpreted addressable to mean optional. The clarification is important. The government will require greater accountability, including a requirement to annually revise the risk analysis, to review policies and procedures and implementation, and to perform penetration testing, said Greene.
• Requiring multifactor authentication (MFA) and encryption of PHI at rest and in transit. “A reasonable person who does security will tell you that should be a requirement,” said Fox. Carr added that the February 2024 Change Healthcare ransomware attack happened because workers at the payment processing company were not using MFA.
• Requiring all entities to verify at least once a year that “business associates” have put into place the required safeguards; the associates would need to provide a written analysis of relevant electronic information systems by a subject matter expert and a written certification that the analysis has been performed and is accurate. In the past, the rule “only required that you sign a business associate agreement” with the associate, which could be a payer, a pharmacy, or another physician practice, said Fox. The rule would require all entities to get certification that the controls are in place.
• Requiring a detailed map of an electronic network. For a physician practice, that means creating an inventory of all the technology assets, including devices, applications, and anything that would touch electronic PHI, and then creating a map of how it comes into the office, flows through it, and departs, said Greene.
• Having a plan of action in the case of a breach. The rule will require written procedures to restore certain relevant systems and data within 72 hours and written incident response plans.

Some physician practices — especially those still relying on passwords instead of more sophisticated MFA or encryption — may have to invest significantly to strengthen their information security, said Greene. Smaller organizations, for example, may need to upgrade systems to ensure that user access is terminated within an hour after someone’s employment ends.

Carr said practices should not view the investments as a burden. The regulation “will force practices to implement best cybersecurity practices,” she said.

Implementing those best practices serves as insurance, said Fox. He suggests that anyone in doubt “talk to someone who’s actually lived through a breach and had to recover.”

Tampa General Hospital in Florida, for instance, recently settled a class action suit, agreeing to pay $6.8 million to patients whose PHI was compromised.

It is not certain whether or when the health cybersecurity rule will be made final.

The incoming Trump administration could cancel or delay the rulemaking process.

Even if it continues, “I would not expect a final rule in 2025,” said Greene. He estimates that the rule would not take effect until at least 2026; healthcare entities would have 180 days to comply. Still, those 180 days can go by fast.

“I would say don’t panic, but don’t ignore it either,” he said.

Is there a connection between antibiotics taken before conception and adverse outcomes, such as reduced fertility, miscarriages, and congenital malformations?

A meta-analysis published in the journal eClinicalMedicine suggests a potential link between antibiotics taken before conception and negative outcomes, such as reduced fertility, miscarriages, and congenital malformations. However, a German expert in reproductive toxicology warned against drawing false conclusions.

“It would be fatal if women who want to have children refused necessary antibiotic treatment because they are afraid of infertility, miscarriages, and malformations,” said Wolfgang Paulus, MD, from the Reproductive Toxicology Advisory Center at the University Women’s Hospital in Ulm, Germany. In an interview, the expert criticized not only the authors’ conclusions but also the selection of studies included in the meta-analysis.

 

Confusion Over Use and Exposure

The meta-analysis, conducted by Bekalu Kassie Alemu, PhD, and colleagues from the Department of Obstetrics and Gynecology at The Chinese University of Hong Kong included 15 studies involving over 1.2 million women to examine how preconception antibiotic use affects fertility and pregnancy outcomes. In most studies (n = 11) that were included in the meta-analysis, fertility was examined as an endpoint, primarily in infertile women. One study involved Danish pharmacy employees who handled antibiotics at work.

“Not only was the therapeutic use of antibiotics not examined in this study, but the biological plausibility is completely lacking in this context,” Paulus noted.

The possible effects of preconception antibiotics on miscarriages were investigated in four studies, while two studies focused on congenital malformations as an endpoint.

 

Mixed Findings on Infertility

Regarding infertility, the authors reported abnormalities in macrolides and sulfonamides. Women who had received macrolide antibiotics, such as azithromycin, before conception showed a 35% reduction in fertility rates.

However, Paulus questioned whether this was solely because of macrolides. “Macrolide antibiotics are typically used for chlamydia, and chlamydia infection is a significant factor in women with unmet fertility desires,” he explained. Often, the chlamydia has already caused damage, such as inflammatory processes in the fallopian tubes, contributing to infertility that cannot be resolved by administering antibiotics.

The meta-analysis also showed that women who received sulfonamide before conception had a 2.35-fold increased likelihood of infertility. However, this association is not always one-sided. The results for tetracyclines were heterogeneous; while chlortetracycline appeared to increase the risk for infertility, exposure to oxytetracycline appeared to decrease it.

Treatment with oxytetracycline and beta-lactam antibiotics (except penicillin G) was associated with a 64% lower likelihood of infertility. The authors also found that fluoroquinolone antibiotics were associated with a 13% lower likelihood of infertility.

 

Miscarriage and Malformation Risks

Alemu and colleagues found a significant association between the use of antibiotics before conception and adverse pregnancy outcomes, showing a 34% increased risk for miscarriages and an 85% higher risk for congenital malformations with the use of trimethoprim during preconception. These findings highlight the need for caution regarding antibiotic use in women who are planning to conceive.

“Most antibiotics have half-lives of only a few hours. Therefore, antibiotics administered before conception can hardly have a direct effect on embryonic development,” Paulus noted. He pointed out that extensive data exist on most antibiotic classes included in this meta-analysis regarding childhood anomalies when used during the sensitive phase of organ development. These data do not indicate an increased risk for malformation. Therefore, the increased risk for malformations due to exposure before conception seems less plausible.

Alemu and colleagues assumed that antibiotics might negatively affect female reproductive health by disrupting the gut microbiome. The reasons for the reduced risk for infertility associated with beta-lactams and fluoroquinolones require further investigation. They reach a significant conclusion: “Preconception antibiotics exposure in females increases the risk of infertility, miscarriage, and congenital anomalies.” However, differences exist between the antibiotic classes. While the risk for infertility, spontaneous miscarriages, and congenital malformations increases with the use of macrolide antibiotics, sulfonamides, and trimethoprim, it decreases with the use of beta-lactams and fluoroquinolone antibiotics.

 

Expert Disagreement

“It is conceivable that the use of antibiotics damages the physiological environment, such as in the vaginal area. This may allow unwanted microbes to establish themselves, leading to more adverse outcomes such as infertility and miscarriages,” Paulus acknowledged.

Disruption of the microbiome due to antibiotic therapy could also result in a deficiency in relevant vitamins and trace elements (eg, folic acid), which could contribute to organogenesis disorders. Therefore, it may be beneficial to stabilize the gut and vaginal flora using probiotics after antibiotic treatment.

However, Paulus disagrees with the study conclusions. First, the studies included in the meta-analysis, which were largely observational, did not allow for the direct effect of antibiotics on the examined outcomes. Second, “quinolone antibiotics are highlighted as positive here, as if they were less problematic for patients trying to have children.”

Quinolone antibiotics are generally “frowned upon,” regardless of whether the patient wants to have children, as they can cause damage to the tendons, muscles, joints, and nervous system. They are currently used only as reserve medications.

“Quinolone antibiotics should not be administered during pregnancy, as they have already caused problems in animal studies, and they should not be used before pregnancy because of their side-effect profile,” Paulus stressed.

 

Serious Consequences

Paulus clarified: “The message must not be that women trying to conceive should avoid antibiotics. This applies to treating bacterial infections regardless of fertility desires, as well as for women trying to conceive who have problematic pathogens found in vaginal swabs.”

In these cases, antibiotic treatment is appropriate, and there should be no fear of adverse effects on fertility or pregnancy outcomes. “If antibiotics are not given and the infection worsens, the patient will be even less likely to conceive successfully.”

Chronic pruritus is a common problem among older individuals. During a session at the Dermatology Days of Paris 2024 conference dedicated to general practitioners, Juliette Delaunay, MD, a dermatologist and venereologist at Angers University Hospital Center in Angers, France, and Gabrielle Lisembard, MD, a general practitioner in the French town Grand-Fort-Philippe, discussed diagnostic approaches and key principles for the therapeutic management of pruritus.

Identifying Causes

“Pruritus in older people is most often linked to physiological changes in the skin caused by aging, leading to significant xerosis. However, before attributing it to aging, we need to rule out several causes,” Delaunay noted.

Beyond simple aging, one must consider autoimmune bullous dermatoses (bullous pemphigoid), drug-related causes, metabolic disorders (can occur at any age), cutaneous T-cell lymphomas, scabies, lice, and HIV infection.

 

Senile Pruritus

Aging-related xerosis can cause senile pruritus, often presenting as itching with scratch marks and dry skin. “This is a diagnosis of exclusion,” Delaunay insisted.

In older individuals with pruritus, initial examinations should include complete blood cell count (CBC), liver function tests, and thyroid-stimulating hormone levels. Syphilis serology, HIV testing, and beta-2 microglobulin levels are secondary evaluations. Renal function analysis may also be performed, and imaging may be required to investigate neoplasia.

“Annual etiological reassessment is essential if the initial evaluation is negative, as patients may later develop or report a neoplasia or hematological disorder,” Delaunay emphasized.

Paraneoplastic pruritus can occur, particularly those linked to hematological disorders (lymphomas, polycythemia, or myeloma).

 

Bullous Pemphigoid

Bullous pemphigoid often begins with pruritus, which can be severe and lead to insomnia. General practitioners should consider bullous pemphigoids when there is a bullous rash (tense blisters with citrine content) or an urticarial or chronic eczematous rash that does not heal spontaneously within a few days. The first-line biologic test to confirm the diagnosis is the CBC, which may reveal significant hypereosinophilia.

The diagnosis is confirmed by a skin biopsy showing a subepidermal blister with a preserved roof, unlike intraepidermal dermatoses, where the roof ruptures.

Direct immunofluorescence revealed deposits of immunoglobulin G antibodies along the dermoepidermal junction.

Approximately 40% of cases of bullous pemphigoid are associated with neurodegenerative diseases, such as stroke, parkinsonism, or dementia syndromes — occurring at a rate two to three times higher than in the general population.

It’s important to identify drugs that induce bullous pemphigoid, such as gliptins, anti-programmed cell death protein 1-programmed death-ligand 1 agents, loop diuretics (furosemide and bumetanide), anti-aldosterones (spironolactone), antiarrhythmics (amiodarone), and neuroleptics (phenothiazines).

“Stopping the medication is not mandatory if the bullous pemphigoid is well controlled by local or systemic treatments and the medication is essential. The decision to stop should be made on a case-by-case basis in consultation with the treating specialist,” Delaunay emphasized.

Treatment consists of very strong local corticosteroid therapy as the first-line treatment. If ineffective, systemic treatments based on methotrexate, oral corticosteroids, or immunomodulatory agents may be considered. Hospitalization is sometimes required.

 

Drug-Induced Pruritus

Drug-induced pruritus is common because older individuals often take multiple medications (antihypertensives, statins, oral hypoglycemics, psychotropic drugs, antiarrhythmics, etc.). “Sometimes, drug-induced pruritus can occur even if the medication was started several months or years ago,” Delaunay emphasized.

The lesions are generally nonspecific and scratching.

“This is a diagnosis of exclusion for other causes of pruritus. In the absence of specific lesions pointing to a dermatosis, eviction/reintroduction tests with treatments should be conducted one by one, which can be quite lengthy,” she explained.

 

Awareness for Scabies

Delaunay reminded attendees to consider scabies in older individuals when classic signs of pruritus flare up at night, with a rash affecting the face, scabs, or vesicles in the interdigital spaces of the hands, wrists, scrotal area, or the peri-mammary region.

“The incidence is increasing, particularly in nursing homes, where outbreaks pose a significant risk of rapid spread. Treatment involves three courses of topical and oral treatments administered on days 0, 7, and 14. All contact cases must also be treated. Sometimes, these thick lesions are stripped with 10% salicylated petroleum jelly. Environmental treatment with acaricides is essential, along with strict isolation measures,” Delaunay emphasized.

Adherent nits on the scalp or other hairy areas should raise suspicion of pediculosis.

 

Neurogenic and Psychogenic Origins

Neurogenic pruritus can occur during a stroke, presenting as contralateral pruritus, or in the presence of a brain tumor or following neurosurgery. Opioid-containing medications may also induce neurogenic pruritus.

The presence of unilateral painful or itchy sensations should prompt the investigation of shingles in older individuals.

Psychogenic pruritus is also common and can arise in the context of psychosis with parasitophobia or as part of anxiety-depression syndromes.

 

Supportive Measures

For managing pruritus, it is essential to:

• Keep nails trimmed short
• Wash with cold or lukewarm water
• Use lipid-rice soaps and syndets
• Avoid irritants, including antiseptics, cologne, no-rinse cleansers, and steroidal or nonsteroidal anti-inflammatory drugs
• Limit bathing frequency
• Avoid wearing nylon, wool, or tight clothing
• Minimize exposure to heat and excessive heating

“Alternatives to scratching, such as applying a moisturizing emollient, can be beneficial and may have a placebo effect,” explained the dermatologist. She further emphasized that local corticosteroids are effective only in the presence of inflammatory dermatosis and should not be applied to healthy skin. Similarly, antihistamines should only be prescribed if the pruritus is histamine-mediated.

Capsaicin may be useful in the treatment of localized neuropathic pruritus.

In cases of neurogenic pruritus, gabapentin and pregabalin may be prescribed, but tolerance can be problematic at this age. Other measures include acupuncture, cryotherapy, relaxation, hypnosis, psychotherapy, and music therapy. In cases of repeated therapeutic failure, patients may be treated with biotherapy (dupilumab) by a dermatologist.

Chronic pruritus is a common problem among older individuals. During a session at the Dermatology Days of Paris 2024 conference dedicated to general practitioners, Juliette Delaunay, MD, a dermatologist and venereologist at Angers University Hospital Center in Angers, France, and Gabrielle Lisembard, MD, a general practitioner in the French town Grand-Fort-Philippe, discussed diagnostic approaches and key principles for the therapeutic management of pruritus.

Identifying Causes

“Pruritus in older people is most often linked to physiological changes in the skin caused by aging, leading to significant xerosis. However, before attributing it to aging, we need to rule out several causes,” Delaunay noted.

Beyond simple aging, one must consider autoimmune bullous dermatoses (bullous pemphigoid), drug-related causes, metabolic disorders (can occur at any age), cutaneous T-cell lymphomas, scabies, lice, and HIV infection.

 

Senile Pruritus

Aging-related xerosis can cause senile pruritus, often presenting as itching with scratch marks and dry skin. “This is a diagnosis of exclusion,” Delaunay insisted.

In older individuals with pruritus, initial examinations should include complete blood cell count (CBC), liver function tests, and thyroid-stimulating hormone levels. Syphilis serology, HIV testing, and beta-2 microglobulin levels are secondary evaluations. Renal function analysis may also be performed, and imaging may be required to investigate neoplasia.

“Annual etiological reassessment is essential if the initial evaluation is negative, as patients may later develop or report a neoplasia or hematological disorder,” Delaunay emphasized.

Paraneoplastic pruritus can occur, particularly those linked to hematological disorders (lymphomas, polycythemia, or myeloma).

 

Bullous Pemphigoid

Bullous pemphigoid often begins with pruritus, which can be severe and lead to insomnia. General practitioners should consider bullous pemphigoids when there is a bullous rash (tense blisters with citrine content) or an urticarial or chronic eczematous rash that does not heal spontaneously within a few days. The first-line biologic test to confirm the diagnosis is the CBC, which may reveal significant hypereosinophilia.

The diagnosis is confirmed by a skin biopsy showing a subepidermal blister with a preserved roof, unlike intraepidermal dermatoses, where the roof ruptures.

Direct immunofluorescence revealed deposits of immunoglobulin G antibodies along the dermoepidermal junction.

Approximately 40% of cases of bullous pemphigoid are associated with neurodegenerative diseases, such as stroke, parkinsonism, or dementia syndromes — occurring at a rate two to three times higher than in the general population.

It’s important to identify drugs that induce bullous pemphigoid, such as gliptins, anti-programmed cell death protein 1-programmed death-ligand 1 agents, loop diuretics (furosemide and bumetanide), anti-aldosterones (spironolactone), antiarrhythmics (amiodarone), and neuroleptics (phenothiazines).

“Stopping the medication is not mandatory if the bullous pemphigoid is well controlled by local or systemic treatments and the medication is essential. The decision to stop should be made on a case-by-case basis in consultation with the treating specialist,” Delaunay emphasized.

Treatment consists of very strong local corticosteroid therapy as the first-line treatment. If ineffective, systemic treatments based on methotrexate, oral corticosteroids, or immunomodulatory agents may be considered. Hospitalization is sometimes required.

 

Drug-Induced Pruritus

Drug-induced pruritus is common because older individuals often take multiple medications (antihypertensives, statins, oral hypoglycemics, psychotropic drugs, antiarrhythmics, etc.). “Sometimes, drug-induced pruritus can occur even if the medication was started several months or years ago,” Delaunay emphasized.

Higher rates of leaving the emergency department (ED) without being seen are linked to increased short-term mortality or hospitalization, according to a cohort study in Ontario, Canada.

“We found that after 2020, there was a 14% higher risk for death or hospitalization within 7 days” among patients who left without being seen (LWBS), Candace McNaughton, MD, PhD, associate professor of medicine at the University of Toronto and scientist at Sunnybrook Research Institute, both in Toronto, Ontario, Canada, told this news organization.

“When we looked at death by itself, there was a 46% higher risk after 2020,” she said. “Even 30 days after a LWBS ED visit, there was still a 5% increased risk for death/hospitalization and a 24% increased risk for death.”

The study was published in the Journal of the American College of Emergency Physicians Open.

 

LWBS Rates Increased 

Researchers used linked administrative data to analyze temporal trends in monthly rates of ED and LWBS visits for adults in Ontario from 2014 to 2023.

They compared the composite outcome of 7-day all-cause mortality or hospitalization following an LWBS ED visit in April 2022‒March 2023 (recent period) with that following an LWBS ED visit in April 2014‒March 2020 (baseline period), after adjustment for age, sex, and Charlson Comorbidity Index (CCI).

In the two periods, patient characteristics were similar across age, sex, neighborhood-level income quartile, history of being unhoused, rurality, CCI, day, time, and mode of arrival. The median age was 40 years for the baseline period and 42 years for the recent period.

Temporal trends showed sustained increases in monthly LWBS rates after 2020, despite fewer monthly ED visits. The rate of LWBS ED visits after April 1, 2020, exceeded the baseline period’s single-month LWBS maximum of 4% in 15 of 36 months.

The rate of 7-day all-cause mortality or hospitalization was 3.4% in the recent period vs 2.9% in the baseline period (adjusted risk ratio [aRR], 1.14), despite similar rates of post-ED outpatient visits (7-day recent and baseline, 38.9% and 39.7%, respectively).

Similar trends were seen at 30 days for all-cause mortality or hospitalization (6.2% in the recent period vs 5.8% at baseline; aRR, 1.05) despite similar rates of post-ED outpatient visits (59.4% and 59.7%, respectively).

After April 1, 2020, monthly ED visits and the proportion of patients who LWBS varied widely.

The proportion of LWBS visits categorized as emergent on the Canadian Triage and Acuity Scale was higher during the recent period (12.9% vs 9.2% in the baseline period), and fewer visits were categorized as semiurgent (22.6% vs 31.9%, respectively). This finding suggested a higher acuity of illness among patients who LWBS in the recent period.

 

LWBS Visits ‘Not Benign’

Results of a preplanned subgroup analysis examining the risk for all-cause mortality after an LWBS visit were “particularly notable,” the authors wrote, with a 46% higher adjusted risk for death at 7 days and 24% higher adjusted risk at 30 days.

The observational study had several limitations, however. The authors could not draw conclusions regarding direct causes of the increased risk for severe short-term adverse health outcomes after an LWBS ED visit, and residual confounding is possible. Cause-of-death information was not available to generate hypotheses for future studies of potential causes. Furthermore, the findings may not be generalizable to systems without universal access to healthcare.

Nevertheless, the findings are a “concerning signal [and] should prompt interventions to address system- and population-level causes,” the authors wrote.

“Unfortunately, because of politics, since 2020, ED closures in Ontario have become more and more common and seem to be affecting more and more Ontarians,” said McNaughton. “It would be surprising if ED closure didn’t play some role in our findings.”

She added, “It is important to note that people in our study were relatively young, with a median age in their 40s; this makes our findings all the more concerning. Clinicians should be aware that LWBS ED visits are not necessarily benign, particularly when rates of LWBS ED visits are high.”

 

Unanswered Questions

The study raised the following questions that the authors are or will be investigating, according to McNaughton: 

• Which patients are at greatest risk for bad outcomes if they leave the ED without being seen, and why?
• How much of the findings might be related to recent ED closures, longer ED wait times, or other factors? Are there geographic variations in risk?
• What can be done in the ED to prevent LWBS ED visits, and what can be changed outside the ED to prevent LWBS ED visits? For example, what can hospitals do to reduce boarding in the ED? If patients leave without being seen, should they be contacted to try to meet their health needs in other ways?
• What worked in terms of maintaining access to outpatient medical care, despite the considerable disruptions starting in 2020, and how can continued success be ensured?

To address the current situation, McNaughton said, “We need consistent, predictable, and sustained investment in our public healthcare system. We need long-term, consistent funding for primary care, ED care, as well as hospital and long-term care.”

“It takes years to recruit and train the teams of people necessary to provide the high-quality medical care that Canadians have a right to. There are no shortcuts,” she concluded.

 

‘Tragic Situation’

American College of Emergency Physicians (ACEP) spokesperson Jesse Pines, MD, chief of clinical innovation at US Acute Care Solutions; clinical professor of emergency medicine at George Washington University in Washington, DC; and professor of emergency medicine at Drexel University in Philadelphia, commented on the study for this news organization.

“Similar to what the authors found in their report, LWBS and other metrics — specifically boarding — have progressively increased in the United States, in particular, since the early part of 2021,” he said. “The primary factor in the US driving this, and one that ACEP is trying to address on a national scale, is the boarding of admitted patients.”

When the number of boarded patients increases, there is less space in the ED for new patients, and waits increase, Pines explained. Some patients leave without being seen, and a subset of those patients experience poor outcomes. “It’s a tragic situation that is worsening.”

“Emergency physicians like me always worry when patients leave without being seen,” he said. While some of those patients have self-limited conditions that will improve on their own, “some have critical life-threatening conditions that require care and hospitalization. The worry is that these patients experience poorer outcomes,” Pines said. “The authors showed that this is increasingly the case in Canada. The same is likely true in the US.”

The study was funded by the Canadian Institutes of Health Research. McNaughton and Pines declared no relevant financial relationships.

Nevertheless, the findings are a “concerning signal [and] should prompt interventions to address system- and population-level causes,” the authors wrote.

“Unfortunately, because of politics, since 2020, ED closures in Ontario have become more and more common and seem to be affecting more and more Ontarians,” said McNaughton. “It would be surprising if ED closure didn’t play some role in our findings.”

She added, “It is important to note that people in our study were relatively young, with a median age in their 40s; this makes our findings all the more concerning. Clinicians should be aware that LWBS ED visits are not necessarily benign, particularly when rates of LWBS ED visits are high.”

 

Unanswered Questions

The study raised the following questions that the authors are or will be investigating, according to McNaughton: 

• Which patients are at greatest risk for bad outcomes if they leave the ED without being seen, and why?
• How much of the findings might be related to recent ED closures, longer ED wait times, or other factors? Are there geographic variations in risk?
• What can be done in the ED to prevent LWBS ED visits, and what can be changed outside the ED to prevent LWBS ED visits? For example, what can hospitals do to reduce boarding in the ED? If patients leave without being seen, should they be contacted to try to meet their health needs in other ways?
• What worked in terms of maintaining access to outpatient medical care, despite the considerable disruptions starting in 2020, and how can continued success be ensured?

To address the current situation, McNaughton said, “We need consistent, predictable, and sustained investment in our public healthcare system. We need long-term, consistent funding for primary care, ED care, as well as hospital and long-term care.”

“It takes years to recruit and train the teams of people necessary to provide the high-quality medical care that Canadians have a right to. There are no shortcuts,” she concluded.

 

‘Tragic Situation’

American College of Emergency Physicians (ACEP) spokesperson Jesse Pines, MD, chief of clinical innovation at US Acute Care Solutions; clinical professor of emergency medicine at George Washington University in Washington, DC; and professor of emergency medicine at Drexel University in Philadelphia, commented on the study for this news organization.

“Similar to what the authors found in their report, LWBS and other metrics — specifically boarding — have progressively increased in the United States, in particular, since the early part of 2021,” he said. “The primary factor in the US driving this, and one that ACEP is trying to address on a national scale, is the boarding of admitted patients.”

When the number of boarded patients increases, there is less space in the ED for new patients, and waits increase, Pines explained. Some patients leave without being seen, and a subset of those patients experience poor outcomes. “It’s a tragic situation that is worsening.”

“Emergency physicians like me always worry when patients leave without being seen,” he said. While some of those patients have self-limited conditions that will improve on their own, “some have critical life-threatening conditions that require care and hospitalization. The worry is that these patients experience poorer outcomes,” Pines said. “The authors showed that this is increasingly the case in Canada. The same is likely true in the US.”

The study was funded by the Canadian Institutes of Health Research. McNaughton and Pines declared no relevant financial relationships.

The quality and credibility of scientific publications have received increasing scrutiny. Findings from studies by Maria Ángeles Oviedo-García, PhD, from the Department of Business and Marketing at the University of Seville in Spain, highlight growing concerns about the integrity of published research. Insights from the journal Science and the US blog Retraction Watch reveal similar concerns regarding research integrity.

Artificial Intelligence (AI) Spurs Low-Quality Submissions

According to a report in Science, journals are inundated with low-quality contributions such as letters and comments generated by AI. Daniel Prevedello, MD, editor in chief of Neurosurgical Review, announced that the journal would temporarily stop accepting these submissions because of their poor quality.

Neurosurgical Review is not the only journal to experience low-quality submissions. In the journal Oral Oncology Reports (Elsevier), comments comprised 70% of the content, whereas in the International Journal of Surgery Open (Wolters Kluwer), they accounted for nearly half. In Neurosurgical Review, letters, comments, and editorials made up 58% of the total content from January to October 2024, compared with only 9% in the previous year.

This trend benefits authors by allowing them to inflate their publication lists with quickly produced contributions that bypass peer review. Publishers may also profit, as many charge fees to publish comments. Additionally, universities and research institutions find this type of content generation useful as more publications can enhance their reputation.

 

Concerns Over Peer Reviews

The troubling behavior described by Oviedo-García in the journal Scientometrics raises further doubts. An analysis of 263 peer reviews from 37 journals revealed that reviewers often used identical or very similar phrases in their evaluations, regardless of the content. In one case, the reviewer used the same wording in 52 reviews. This suggests that some reviewers read the studies that they are supposed to evaluate only superficially. Such practices can lead to valueless reviews and jeopardize the integrity of scientific literature. “Some other researchers will probably base their future research on these fake reports, which is frightening, especially when it comes to health and medicine,” Oviedo-García stated.

She suspects that the reviewers may have relied on templates to produce their reports quickly. This allowed them to list this work on their resumes for potential career advantages. Some reviewers have reportedly even “requested” the authors of the studies they reviewed to cite their own scientific work.

 

AI Complicates Peer Review

The process of research and publication has become increasingly challenging in recent years, and more standard and predatory journals allow anyone to publish their work for a fee. Roger W. Byard, MD, PhD, from the University of Adelaide in Australia, explained this trend in the journal Forensic Science, Medicine and Pathology. AI is increasingly being used to generate articles. At international conferences, experts have highlighted claims that AI can complete papers in just a few weeks and dissertations in less than a year. According to the authors of a letter in Critical Care, generative AI is infiltrating the peer review process.

Moreover, the peer review process can be bypassed by publishing research findings on online platforms (eg, preprint servers). Another issue is that some publications have hundreds of authors who can extend their publication list in this manner, even if their contribution to the publication is ambiguous or not substantial.

In a guest article for the Laborjournal, Ulrich Dirnagl, MD, PhD, from the Charité — Universitätsmedizin Berlin in Germany, emphasized that the scientific papers have become so complex that two or three experts often cannot thoroughly assess everything presented. The review process is time-consuming and can take several days for reviewers. Currently, very few people have time, especially because it is an unpaid and anonymous task. Dirnagl stated, “the self-correction of science no longer works as it claims.”

The old Russian saying ‘Dowjerjaj, no prowjerjaj: Trust, but verify’  remains a timeless recommendation that is likely to stay relevant for years to come.

A few items bring back unpleasant memories of COVID-19, such as masks. However, they are among the simplest and most effective ways to prevent the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). If everyone had worn them correctly, the transmission could have been reduced as much as ninefold, according to a theoretical study published in Physical Review E by Richard P. Sear, PhD, from the University of Surrey, Guildford, England.

Study Overcomes Limitations

This study aimed to address the limitations of epidemiological investigations of masks, which can be complex and error-prone. Sear used data obtained from the UK’s COVID-19 app, totaling 7 million contacts, to create a mathematical model of virus transmission, focusing on the correlation between contact duration and infection. The model estimates that if all UK residents had worn masks during every potential exposure, virus transmission would have been approximately nine times lower.

Although this is a mathematical model, it adds to the growing evidence that supports the benefits of masks. Masks are among the best strategies for treating SARS-CoV-2. This conclusion has been supported by several systematic reviews and additional statistical studies. Conversely, the decision to relax and eliminate mask regulations has had consequences that have received little attention.

As expected, removing the mask mandate leads to increased virus transmission, resulting in more hospitalizations and deaths. A 2024 study estimated that in Japan, where cultural factors lead to much higher mask use in public than in Europe, the decline in mask use from 97% of the population in 2022 to 63% in October 2023 may have caused an additional 3500 deaths.

 

Impact Beyond SARS-CoV-2

One remarkable effect of non-pharmaceutical interventions during the pandemic was the probable extinction of an entire influenza strain (B/Yamagata), which could improve future influenza vaccines and significantly reduce the spread of respiratory syncytial virus. While this was not solely caused by masks, it was also influenced by emergency measures such as lockdowns and social distancing. These behavioral changes can positively alter the landscape of infectious diseases.

Masks play a role in reducing influenza transmission during pandemics. Their effectiveness has been supported by several studies and systematic reviews on a wide range of respiratory viruses. A randomized clinical trial involving 4647 Norwegian participants from February to April 2023, published in May 2024 by the British Medical Journal, suggested that wearing a mask reduces the incidence of respiratory symptoms. Specifically, 8.9% of those who wore masks reported respiratory symptoms during the study period compared with 12.2% of those who did not, representing a relative risk reduction of 27%.

Widespread mask use could also protect against other factors such as fine particulate matter, indirectly reducing the risk for various health conditions. A retrospective study involving 7.8 million residents in the Chinese city of Weifang, published in December 2024 by BMC Public Health, suggested that mask use during the pandemic may have also protected the population from pollution, reducing the number of stroke cases by 38.6% over 33 months of follow-up.

Although there are still voices in bioethics calling for the reintroduction of mask mandates in public places, it is unlikely that, barring emergencies, mask mandates are politically and socially acceptable today. Mask use is also considered a politically polarizing topic in several Western countries. Nevertheless, it is worth considering whether, as we move away from the acute phase of the COVID-19 pandemic, we can more objectively promote the use of masks in public places.

Communicating the importance of public health initiatives and persuading people to support them is a well-known challenge. However, scientific literature offers valuable insights. These include encouraging people to rely on rational thinking rather than emotions and providing information on how masks protect those around them. The fact that East Asian cultures tend to have a more positive relationship with the use of masks shows that, in principle, it is possible to make them acceptable. Data from studies suggest that, as we prepare for potential future pandemics, it may be time to move past polarization and reintroduce masks — not as a universal mandate but as an individual choice for many.

The pediatrician’s first patient of the day was an 8-year-old boy, accompanied by both of his parents. It was the boy’s third visit in just over a week for fever and left-sided neck swelling, and the family was understandably anxious for answers.

“The antibiotics don’t seem to be working,” the mother explained. “He still has fever every day, as high as 104, and his neck looks just as swollen.”

A quick review of the chart revealed the boy’s initial diagnosis had been bacterial lymphadenitis, for which amoxicillin-clavulanate had been prescribed. Three days later, given lack of clinical improvement, therapy was transitioned to clindamycin. On examination, the boy was febrile and ill-appearing with a 3-cm by 5-cm tender, non-fluctuant swelling over the left sternocleidomastoid muscle. 

 

The pediatrician ran through a quick mental checklist of diagnostic possibilities for his patient’s continued symptoms. Staphylococcal lymphadenitis still seemed possible. Could the boy be infected with methicillin-resistant Staphylococcus aureus that was also clindamycin resistant? Alternately, perhaps the problem was “source control” and the boy had developed an occult neck abscess that needed to be drained. An ultrasound could help sort that out. Finally, the pediatrician considered less common bacterial causes of lymph node swelling and fever. He placed Bartonella henselae, the cause of cat scratch disease, near the top of his list. “I’ve never seen it,” he told the parents, “But we could also consider tularemia.”

Tularemia is a rare zoonotic infection caused by Francisella tularenis. On average, 200 cases of tularemia are reported in the United States each year, and the incidence of disease is increasing, according to a surveillance report released by the Centers for Disease Control and Prevention in December 2023.¹

Between 2011 and 2022, 2462 tularemia cases were reported in the United States. That translated to an average annual incidence of 0.064 per 100,000 population, an increase of 56% compared with 2001-2010. Forty-seven states reported at least one case of tularemia, although half of all reported cases came from four states — Arkansas (18%), Kansas (11%), Missouri (11%), and Oklahoma (10%). The incidence of tularemia was highest in children ages 5-9 years old, older men, and American Indian or Alaska Natives individuals. Although cases occurred year-round, 78% had symptom onset May through September. 

In the United States, most human cases of tularemia have been arthropod borne, transmitted by the bite of an infected tick or deer fly. Infection also can be spread through contact with infected animals or animal tissue, particularly rabbits, hares, muskrats, prairie dogs, and other rodents, including hamsters. Outbreaks of tularemia have occurred among pet store hamsters, and at least one child in the United States developed tularemia after being bitten by a pet hamster.

Tularemia is almost always associated with fever but other clinical manifestations vary by the type of exposure. Ulceroglandular disease occurs after a tick or deer fly bite or after handling an infected animal. An ulcer develops at the site where the bacteria entered the body, along with enlargement of regional lymph nodes. Less commonly, lymph node swelling can occur without the development of an ulcer. If the bacteria enter through the eye, symptoms include conjunctivitis and swelling of pre-auricular lymph nodes. Eating or drinking contaminated food or water is associated with sore throat, mouth ulcers, tonsillitis, and swelling of lymph glands in the neck. Pneumonic tularemia, the most serious form of the disease, typically happens after inhaling bacteria-containing dust or aerosols and is associated with cough, chest pain, and difficulty breathing. Pneumonic tularemia can develop if other forms of tularemia are untreated, and the bacteria spread to the lung.

Back in the exam room, the pediatrician carefully re-examined the boy’s scalp. A 1-cm poorly healing ulcer on the left occiput added support for the diagnosis of ulceroglandular tularemia, the most common form of the disease in children. Serologic testing ultimately confirmed the diagnosis and the boy’s symptoms resolved with treatment.

Gentamicin administered intravenously or intramuscularly is the drug of choice for the treatment of tularemia in children. Ciprofloxacin is considered an alternative but is not approved by the U.S. Food and Drug Administration for this indication.

The pediatrician reported the case of tularemia to his local health department. Tularemia is a nationally notifiable disease in the United States; state health departments report to the CDC through the National Notifiable Diseases Surveillance System. In turn, public health authorities shared information to prevent tularemia. Steps to prevent tick and deer fly bites include the use of an Environmental Protection Agency–registered insect repellent. Individuals who hunt, trap, or skin animals are encouraged to wear gloves when handling animals —especially rabbits, muskrats, and prairie dogs — and cook game meat thoroughly. Tularemia can be inadvertently aerosolized if an infected animal or carcass is run over with a tractor or lawnmower. Checking for carcasses before mowing may reduce the risk.

On examination, the boy was febrile and ill-appearing with a 3-cm by 5-cm tender, non-fluctuant swelling over the left sternocleidomastoid muscle. 

 

The pediatrician ran through a quick mental checklist of diagnostic possibilities for his patient’s continued symptoms. Staphylococcal lymphadenitis still seemed possible. Could the boy be infected with methicillin-resistant Staphylococcus aureus that was also clindamycin resistant? Alternately, perhaps the problem was “source control” and the boy had developed an occult neck abscess that needed to be drained. An ultrasound could help sort that out. Finally, the pediatrician considered less common bacterial causes of lymph node swelling and fever. He placed Bartonella henselae, the cause of cat scratch disease, near the top of his list. “I’ve never seen it,” he told the parents, “But we could also consider tularemia.”

Tularemia is a rare zoonotic infection caused by Francisella tularenis. On average, 200 cases of tularemia are reported in the United States each year, and the incidence of disease is increasing, according to a surveillance report released by the Centers for Disease Control and Prevention in December 2023.¹

Between 2011 and 2022, 2462 tularemia cases were reported in the United States. That translated to an average annual incidence of 0.064 per 100,000 population, an increase of 56% compared with 2001-2010. Forty-seven states reported at least one case of tularemia, although half of all reported cases came from four states — Arkansas (18%), Kansas (11%), Missouri (11%), and Oklahoma (10%). The incidence of tularemia was highest in children ages 5-9 years old, older men, and American Indian or Alaska Natives individuals. Although cases occurred year-round, 78% had symptom onset May through September. 

In the United States, most human cases of tularemia have been arthropod borne, transmitted by the bite of an infected tick or deer fly. Infection also can be spread through contact with infected animals or animal tissue, particularly rabbits, hares, muskrats, prairie dogs, and other rodents, including hamsters. Outbreaks of tularemia have occurred among pet store hamsters, and at least one child in the United States developed tularemia after being bitten by a pet hamster.

Tularemia is almost always associated with fever but other clinical manifestations vary by the type of exposure. Ulceroglandular disease occurs after a tick or deer fly bite or after handling an infected animal. An ulcer develops at the site where the bacteria entered the body, along with enlargement of regional lymph nodes. Less commonly, lymph node swelling can occur without the development of an ulcer. If the bacteria enter through the eye, symptoms include conjunctivitis and swelling of pre-auricular lymph nodes. Eating or drinking contaminated food or water is associated with sore throat, mouth ulcers, tonsillitis, and swelling of lymph glands in the neck. Pneumonic tularemia, the most serious form of the disease, typically happens after inhaling bacteria-containing dust or aerosols and is associated with cough, chest pain, and difficulty breathing. Pneumonic tularemia can develop if other forms of tularemia are untreated, and the bacteria spread to the lung.

Back in the exam room, the pediatrician carefully re-examined the boy’s scalp. A 1-cm poorly healing ulcer on the left occiput added support for the diagnosis of ulceroglandular tularemia, the most common form of the disease in children. Serologic testing ultimately confirmed the diagnosis and the boy’s symptoms resolved with treatment.

Gentamicin administered intravenously or intramuscularly is the drug of choice for the treatment of tularemia in children. Ciprofloxacin is considered an alternative but is not approved by the U.S. Food and Drug Administration for this indication.

The pediatrician reported the case of tularemia to his local health department. Tularemia is a nationally notifiable disease in the United States; state health departments report to the CDC through the National Notifiable Diseases Surveillance System. In turn, public health authorities shared information to prevent tularemia. Steps to prevent tick and deer fly bites include the use of an Environmental Protection Agency–registered insect repellent. Individuals who hunt, trap, or skin animals are encouraged to wear gloves when handling animals —especially rabbits, muskrats, and prairie dogs — and cook game meat thoroughly. Tularemia can be inadvertently aerosolized if an infected animal or carcass is run over with a tractor or lawnmower. Checking for carcasses before mowing may reduce the risk.

The pediatrician’s first patient of the day was an 8-year-old boy, accompanied by both of his parents. It was the boy’s third visit in just over a week for fever and left-sided neck swelling, and the family was understandably anxious for answers.

“The antibiotics don’t seem to be working,” the mother explained. “He still has fever every day, as high as 104, and his neck looks just as swollen.”

A quick review of the chart revealed the boy’s initial diagnosis had been bacterial lymphadenitis, for which amoxicillin-clavulanate had been prescribed. Three days later, given lack of clinical improvement, therapy was transitioned to clindamycin. On examination, the boy was febrile and ill-appearing with a 3-cm by 5-cm tender, non-fluctuant swelling over the left sternocleidomastoid muscle.
