A history of concussion can have serious long-term mental health implications for women, even years after giving birth, according to a new study.

Researchers looked at all people who delivered babies in Ontario, Canada, and found that those with a predelivery history of concussion were 25% more likely to have a serious mental illness up to 14 years after giving birth than those with no history of concussion.

The findings indicate the need for early identification and screening of women with a history of concussion, as well as ongoing, long-term supports to prevent adverse psychiatric outcomes, wrote the authors.

“I played a lot of sports growing up, and I definitely would not have thought about how a concussion could affect childbearing or parenting,” author Samantha Krueger, RM, MSc, told this news organization. She completed the research as part of her studies at the University of Toronto, Ontario.

The data were published on November 4 in The Journal of Clinical Psychiatry.
 

Implications for Prevention

“Birthing people, and women in general, are an often-overlooked population in the scientific literature on traumatic brain injury, including concussion. There is a potential interplay between concussion history and the challenges of being a new parent (such as labor and birth, lack of sleep, and increased noise) that make this an important population to study,” said Krueger.

The researchers conducted a population-based cohort study of all women who gave birth in Ontario between 2007 and 2017. Follow-up continued until 2021. The primary outcome was severe maternal mental illness, which was defined as a psychiatric emergency department visit, psychiatric hospital admission, or self-harm or suicide in the 14 years after delivery.

The researchers identified 18,064 women with a predelivery history of concussion and 736,689 women without a history of concussion during the study period. Women with a predelivery history of concussion were more likely than those without such a history to live in a rural area and have a history of assault or mental illness.

Overall, 11.3% (n = 2033) of the women with a predelivery history of concussion developed severe maternal mental illness (14.7 per 1000 person-years), compared with 6.8% (n = 49,928) of the women without a predelivery history of concussion (7.9 per 1000 person-years).

The adjusted hazard ratio (aHR) was 1.25. The association was strongest in women who had a predelivery history of concussion but no history of mental illness (aHR, 1.33).

“We hope to increase awareness of the seriousness of having a concussion, even when it is considered a mild head injury,” Krueger said. “The results have important implications for concussion prevention measures for young people and for the provision of postpartum supports (such as mental health and other social supports like sleep relief) to mitigate the risk of serious mental illness outcomes in birthing people with a history of concussion.”

Healthcare providers, including maternity care providers, should be asking about concussion history and providing mental health screening and supports to clients and their families to detect mental illness before a serious outcome occurs, Krueger added.

“Maternity care providers can help birthing people and their families set up supports for after the baby is born and teach families about mental health symptoms to look out for. It’s also important that providers be certain that their care is trauma informed to avoid triggering a trauma response when providing care,” she said.
 

Area of Concern

“This research is novel and highlights an area of major concern,” Simon Sherry, PhD, professor of psychology and neuroscience at Dalhousie University in Halifax, Nova Scotia, Canada, told this news organization. Sherry did not participate in the study.

“Postpartum depression occurs in approximately 10%-25% of mothers, but it is likely that many more cases go undiagnosed. It is attributed to hormonal changes, genetic predisposition, and environmental factors, and while previous depression or mental illness is frequently considered a risk factor, traumatic brain injuries or concussions usually are not,” Sherry said.

“Mothers are already an at-risk population for mental illness, as illustrated by the high rates of postpartum depression, and so are people with a history of concussion or traumatic brain injury. What sets this study apart is that it shows the heightened risk for women with the combination of those two distinct risk factors. Identifying these risk factors is essential to providing preventive care. If care providers know a patient is at increased risk when starting a pregnancy, then they will likely catch warning signs earlier,” he said.

“Additionally, as the article suggests, maternal mental health often is not studied beyond the first postpartum year,” Sherry said.

“Mental health struggles during the first postpartum year have largely been normalized as part of the transition into parenthood, but mental health issues among parents later in life are less accepted. After birth, so much emphasis is moved from the parent to the child. Parents rightly prioritize their children, but our job as care providers is to ensure we are also prioritizing them. The prolonged period of this study helps illustrate how important the practice of prioritizing mothers’ mental health is,” he added.

The study was supported by ICES, which is funded by an annual grant from the Ontario Ministry of Health and the Ministry of Long-Term Care. The Canadian Institutes of Health Research also supported the study. Krueger is supported by a Canadian Institutes of Health Research Canada Graduate Scholarship Masters Award. Sherry reported no relevant financial relationships.

The viral burden of SARS-CoV-2 on floors, even in healthcare worker–only areas, was strongly associated with COVID-19 outbreaks in two acute-care hospitals, according to a new study from Ontario, Canada.

With every 10-fold increase in viral copies, the chance of an impending outbreak of COVID-19 rose 22-fold. The results suggest that frequent floor sampling could play an important role in a more localized surveillance of the virus, the authors wrote.

“These data add to the mounting evidence that built environment detection for SARS-CoV-2 may provide an additional layer of monitoring and could help inform local infection prevention and control measures,” they wrote.

The study was published online in Infection Control & Hospital Epidemiology. 
 

Preventing Future Suffering 

The current study builds on the researchers’ previous work, which found the same correlation between viral load on floors and COVID outbreaks in long-term care homes. 

Currently, the best-known method of environmental surveillance for COVID is wastewater detection. “Swabbing the floors would be another approach to surveillance,” senior author Caroline Nott, MD, infectious disease physician at the Ottawa Hospital, said in an interview. 

“We do have environmental surveillance with wastewater, but while this may tell you what’s going on in the city, it doesn’t tell you what is going on in a particular ward of a hospital, for instance,” she added. 

Nott and her colleagues believe that swabbing, which is easy and relatively inexpensive, will become another tool to examine the built environment. “Instead of having to close a whole hospital, for example, we could just close one room instead of an entire ward if swabbing showed a high concentration of COVID,” Nott said. 

The current study was conducted at two hospitals in Ontario between July 2022 and March 2023. The floors of healthcare worker–only areas on four inpatient adult wards were swabbed. These areas included changing rooms, meeting rooms, staff washrooms, nursing stations, and interdisciplinary team rooms.

SARS-CoV-2 RNA was detected on 537 of 760 floor swabs (71%). The overall positivity rate in the first hospital was 90% (n = 280). In the second hospital, the rate was 60% (n = 480).

Four COVID-19 outbreaks occurred in the first acute care hospital, and seven outbreaks occurred at the second hospital. Outbreaks occurred mostly among hospitalized patients (140 cases), but also in four hospital workers.

COVID-19 still requires vigilance, said Nott. “We weren’t prepared for COVID, and so as a result, many people died or have suffered long-term effects, especially vulnerable people like those being treated in hospital or in long-term care facilities. We want to develop methods to prevent similar suffering in the future, whether it’s a new COVID variant or a different pathogen altogether.” 
 

Changing Surveillance Practice?

“This is a good study,” Steven Rogak, PhD, professor of mechanical engineering at the University of British Columbia (UBC) in Vancouver, Canada, said in an interivew. “The fundamental idea is that respiratory droplets and aerosols will deposit on the floor, and polymerase chain reaction [PCR] tests of swabs will provide a surrogate measurement of what might have been inhaled. There are solid statistics that it worked for the hospitals studied,” said Rogak, who studies aerosols at UBC’s Energy and Aerosols Laboratory. Rogak did not participate in the study. 

“The authors note several limitations, including that increased healthcare worker testing may have been triggered by the higher values of PCR counts from the floor swabs. But this doesn’t seem to be a problem to me, because if the floor swabs motivate the hospital to test workers more, and that results in identifying outbreaks sooner, then great,” he said.

“Another limitation is that if the hospital has better HVAC or uses air purifiers, it could remove the most infectious aerosols, but the large droplets that fall quickly to the ground would remain, and this would still result in high PCR counts from floor swabs. In this case, perhaps the floor swabs would be a poorer indication of impending outbreaks,” said Rogak.

Determining the best timing and location for floor swabbing might be challenging and specific to the particular hospital, he added. ”For example, you would not want to take swabs from floors right after they are cleaned. Overall, I think this method deserves further development, and it could become a standard technique, but the details might require refinement for widespread application.”

Adrian Popp, MD, chair of the Infectious Disease Service at Huntington Hospital–Northwell Health in New York, said that, although interesting, the study would not change his current practice.

“I’m going to start testing the environment in different rooms in the hospital, and yes, I might find different amounts of COVID, but what does that mean? If pieces of RNA from COVID are on the floor, the likelihood is that they’re not infectious,” Popp said in an interview.

“Hospital workers do get sick with COVID, and sometimes they are asymptomatic and come to work. Patients may come into the hospital for another reason and be sick with COVID. There are many ways people who work in the hospital, as well as the patients, can get COVID. To me, it means that in that hospital and community there is a lot of COVID, but I can’t tell if there is causation here. Who is giving COVID to whom? What am I supposed to do with the information?” 

The study was supported by the Northern Ontario Academic Medicine Association Clinical Innovation Opportunities Fund, the Ottawa Hospital Academic Medical Organization Innovation Fund, and a Canadian Institutes of Health Research Operating Grant. One author was a consultant for ProofDx, a startup company creating a point-of-care diagnostic test for COVID-19, and is an advisor for SIGNAL1, a startup company deploying machine-learning models to improve inpatient care. Nott, Rogak, and Popp reported having no relevant financial relationships.

A psychosocial intervention designed to improve depressive symptoms and promote good parenting skills can be an effective way of treating male postpartum depression, according to new research.

In a study conducted in Pakistan, about 70% fathers with postpartum depression who received the intervention showed complete remission of their depressive symptoms and experienced enhanced relationships with their children and domestic partners.

Called Learning Through Play Plus Dads (LTP + Dads), the intervention, which can be delivered by community health workers, could improve paternal mental health and child development not only in Pakistan but also in other populations, the authors stated.

The results of the study were published on October 2, 2024, in JAMA Psychiatry.
 

Stigmatized and Understudied

“Pakistan is a patriarchal society with strict gender roles, and male mental health, particularly postpartum depression in new fathers, is stigmatized and understudied,” lead investigator Ishrat Husain, MD, a senior scientist at the Centre for Addiction and Mental Health and associate professor of psychiatry at the University of Toronto in Ontario, Canada, said in an interview.

“Historically, and rightly so, the focus has always been on the mother, but men also experience significant emotional challenges as they adapt to being a parent. Fathers are also in need of support,” said Husain.

Male postpartum depression is prevalent in all populations. Globally, about 10% fathers have postpartum depression. But in societies like Pakistan, rates of male postpartum depression have been reported to be as high as 23.5%.

The study included 357 fathers aged 18 years or older (mean age, 31.44 years) with a Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, diagnosis of major depressive episode and a child younger than 30 months.

They were randomly assigned either to receive treatment as usual (n = 186) or to participate in the LTP + Dads program (n = 171). LTP + Dads is a parenting and mental health initiative adapted from a similar program for Pakistani mothers. It combines parenting skills training, play therapy, and cognitive behavioral therapy. In this study, the initiative was delivered by community health workers in 12 group sessions over 4 months. Sessions took place weekly for the first 2 months and biweekly thereafter.

The researchers assessed changes in the 17-item Hamilton Depression Rating Scale (HDRS-17) score at 4 months and at 6 months. They also looked at anxiety symptoms; parenting stress; intimate partner violence; functioning; quality of life; and child social, emotional, and physical health outcomes.
 

Improved Child Development

There were significantly greater reductions in HDRS-17 scores in the LTP + Dads group than in the treatment as usual group at 4 months (group difference ratio [GDR], 0.66; P < .001) and at 6 months (GDR, 0.67; P < .001).

Similar results were seen for anxiety (GDR, 0.62; P < .001), parenting stress (GDR, −12.5; P < .001), intimate partner violence (GDR, 0.89; P = .05), disability (GDR, 0.77; P = .03), and health-related quality of life (GDR, 12.7; P < .001) at 4 months. The differences in depression and parenting stress were sustained at 6 months.

In addition, children of fathers who received the parenting intervention showed significantly greater improvements in social-emotional development scores (mean difference, −20.8; P < .001) at 6 months than children of those who received the treatment as usual.

“We believe that this program could also be successful in other countries, including Canada,” said Husain. “Canada is multicultural, and similar patterns of male postpartum depression probably exist here. We know that cultural and social pressures create barriers to seeking mental health support for men. Stigma and cultural beliefs often prevent new fathers from seeking the help they need. Programs like LTP + Dads can help men transition to their new role as fathers by giving them support to process their emotions,” he said.

Husain added that the program will be expanded throughout Pakistan to include about 4000 fathers and their partners.
 

‘Remarkable’ Success Rate

“Postpartum depression in men is still something that people are trying to understand,” John Ogrodniczuk, MD, professor of psychiatry and director of the psychotherapy program at The University of British Columbia, Vancouver, Canada, said in an interview. He did not participate in the study.

“Obviously, men aren’t going through the same endocrine changes that women are, but nonetheless, a lot of men do actually struggle with it,” said Ogrodniczuk, who is also the founder of HeadsUpGuys, a mental health resource for men.

“Understandably, most of the literature is around postpartum depression in women, not so much around men. The positive results seen here are interesting, especially in a country that is patriarchal and where there is not a lot of uptake of mental health interventions and services by men,” he said.

“The success rate of this psychosocial intervention is remarkable, so I am excited to see that the researchers have secured funding to expand the study and validate their results with a larger group of participants,” Simon B. Sherry, PhD, professor of psychology and neuroscience at Dalhousie University, Halifax, Nova Scotia, Canada, said in an interview.

“I am also encouraged by the inclusion of play-based activities in addition to cognitive behavioral therapy. Perhaps more than any other role we hold through life, the role of parent comes with copious societal and personal expectations, plus with all that pressure, transitioning into that role is hard for everyone, but especially for those with postpartum depression. Supporting parents and improving their mental well-being goes a long way toward raising mentally healthy kids,” said Sherry, who was not part of the study.

The study was funded by a grant from Grand Challenges Canada, an Academic Scholars Award from the Department of Psychiatry at the University of Toronto, and a Tier 2 Canada Research Chair from the Canadian Institutes of Health Research. Husain reported receiving grants from COMPASS Pathfinder, stock options from Mindset Pharma, and personal fees from Wake Network, outside the submitted work. He previously served as a trustee for the Pakistan Institute of Living and Learning. Ogrodniczuk and Sherry reported no relevant financial relationships.

A psychosocial intervention designed to improve depressive symptoms and promote good parenting skills can be an effective way of treating male postpartum depression, according to new research.

In a study conducted in Pakistan, about 70% fathers with postpartum depression who received the intervention showed complete remission of their depressive symptoms and experienced enhanced relationships with their children and domestic partners.

Called Learning Through Play Plus Dads (LTP + Dads), the intervention, which can be delivered by community health workers, could improve paternal mental health and child development not only in Pakistan but also in other populations, the authors stated.

The results of the study were published on October 2, 2024, in JAMA Psychiatry.
 

Stigmatized and Understudied

“Pakistan is a patriarchal society with strict gender roles, and male mental health, particularly postpartum depression in new fathers, is stigmatized and understudied,” lead investigator Ishrat Husain, MD, a senior scientist at the Centre for Addiction and Mental Health and associate professor of psychiatry at the University of Toronto in Ontario, Canada, said in an interview.

“Historically, and rightly so, the focus has always been on the mother, but men also experience significant emotional challenges as they adapt to being a parent. Fathers are also in need of support,” said Husain.

Male postpartum depression is prevalent in all populations. Globally, about 10% fathers have postpartum depression. But in societies like Pakistan, rates of male postpartum depression have been reported to be as high as 23.5%.

The study included 357 fathers aged 18 years or older (mean age, 31.44 years) with a Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, diagnosis of major depressive episode and a child younger than 30 months.

They were randomly assigned either to receive treatment as usual (n = 186) or to participate in the LTP + Dads program (n = 171). LTP + Dads is a parenting and mental health initiative adapted from a similar program for Pakistani mothers. It combines parenting skills training, play therapy, and cognitive behavioral therapy. In this study, the initiative was delivered by community health workers in 12 group sessions over 4 months. Sessions took place weekly for the first 2 months and biweekly thereafter.

The researchers assessed changes in the 17-item Hamilton Depression Rating Scale (HDRS-17) score at 4 months and at 6 months. They also looked at anxiety symptoms; parenting stress; intimate partner violence; functioning; quality of life; and child social, emotional, and physical health outcomes.

Replacing meat with plant-based meat alternatives (PBMAs) can improve cardiovascular disease risk factors, including low-density lipoprotein cholesterol (LDL-C), a review of randomized controlled trials suggested.

Long-term randomized controlled trials and prospective cohort studies that evaluate cardiovascular disease events such as myocardial infarction and stroke are needed to draw definitive conclusions, according to the authors.

“Our take-home is that plant-based meats are a healthy alternative to animal meat, based on intermediate cardiovascular endpoints such as lipids, triglycerides, blood pressure, and other cardiovascular disease risk factors,” said senior author Ehud Ur, MB, professor of medicine at the University of British Columbia, Vancouver, in Canada, and an endocrinologist at St. Paul’s Hospital in Vancouver.

“However, we also found that there’s a lack of clinical outcome trials that would determine definitively whether plant-based meats are healthy. But certainly, everything points in the direction of cardiovascular benefit,” said Dr. Ur.

The review was published on June 25 in the Canadian Journal of Cardiology.
 

Ultraprocessed Foods

PBMAs are foods that mimic meats and contain ingredients such as protein derivatives from soy, pea, wheat, and fungi. A growing number of Canadians are limiting meat or excluding it from their diets. Some are opting to eat PBMAs instead.

But most PBMAs are classified as ultraprocessed foods. Such foods are produced primarily from substances extracted from whole food sources, such as sugar, salt, oil, and protein. Alternatively, they may be created in a laboratory using flavor enhancers and food coloring. This classification has caused the public and health professionals to question the potential health implications of PBMAs, said Dr. Ur.

“One of the concerns is that these products are highly processed, and things that are highly processed are considered bad. And so, are you swapping one set of risks for another?” he said.

To shed more light on this question, Dr. Ur’s team, which was led by Matthew Nagra, ND, of the Vancouver Naturopathic Clinic, assessed the literature on PBMAs and their impact on health.

“While the plant-based meat market has experienced significant growth in recent years and more and more Canadians are enjoying plant-based burgers, surprisingly little is known about how these meat alternatives may impact health and, in particular, cardiovascular disease risk,” Dr. Nagra said in a statement. “Thus, we sought to review the available literature on the topic to identify what is currently known and to provide direction for future research.”
 

Less Saturated Fat, Cholesterol

The researchers assessed the literature that was published from 1970 to 2023 on PBMAs, their contents, nutritional profiles, and impact on cardiovascular disease risk factors, such as cholesterol levels and blood pressure.

They found that, compared with meat, PBMAs had less saturated fat, less cholesterol, more fiber, more carbohydrates, fewer calories, less monounsaturated fat, more polyunsaturated fat, and more sodium.

In addition, several randomized controlled trials showed that PBMAs reduced total cholesterol and LDL-C, as well as apolipoprotein B-100, body weight, and waist circumference. PBMAs were not shown to raise blood pressure, despite some products’ high sodium content.

“No currently available evidence suggests that the concerning aspects of PBMAs (eg, food processing and high sodium content) negate the potential cardiovascular benefits,” wrote the researchers.

Unfortunately, no long-term research has evaluated how these alternatives may affect the risk of developing a myocardial infarction or stroke. Similarly, there is little research on the healthfulness of some common components of PBMAs, such as vital wheat gluten.

To shed light on these important issues would require large clinical trials, involving many patients, and great expense, said Dr. Ur. “Drug companies can afford to do large clinical trials, even if they are expensive to do, because they must do them to get approval for their drug. But these plant-based meats are produced by companies that most likely are not able to do clinical outcome trials. Such trials would have to be done by the National Institutes of Health in the United States, or in Canada, the National Research Council,” he said.

There are many reasons to avoid meat, Dr. Ur added. “There are ethical reasons against killing animals. Then there is the issue of global warming. Meat is a very expensive source of food energy. As an individual, the biggest impact you can make on global warming is to not eat meat. Then there is the argument about personal health, which is where our study comes in. For those people who like the taste of meat and who struggle with giving it up, the PBMAs allow them to have a reasonably diverse diet,” he said.
 

Are Eggs Healthy?

Meat substitutes are helpful for people who want to reduce their cardiovascular disease risk, J. David Spence, MD, professor emeritus of neurology and clinical pharmacology at the University of Western Ontario in London, Canada, wrote in an accompanying editorial.

“Eating too much meat and egg yolk increases cardiovascular risk, and it’s a challenge for patients to learn to eat less meat and cut out egg yolks. If we can find good substitutes that are tasty and enjoyable, that’s a good thing,” Dr. Spence told this news organization.

“Besides plant-based meat substitutes, there is great potential for reduction of cardiovascular risk with the use of egg substitutes,” he said.

Dr. Spence pointed out that two large egg yolks contain 474 mg of cholesterol, almost twice the amount contained in a Hardee’s Monster Thickburger (265 mg).

Cholesterol elevates plasma levels of toxic metabolites of the intestinal microbiome, such as trimethylamine N-oxide (TMAO). Plasma levels of TMAO increase in a linear fashion with egg consumption, and TMAO is bad for the arteries, said Dr. Spence.

“Eggs are terrible and should not be eaten by people at risk for cardiovascular disease. But people don’t understand that because the egg marketing propaganda has been so effective. The yolk is terrible. The egg marketing board is extremely effective in persuading people that eggs are healthy, and they’re not.”

Dr. Spence recommends using egg substitutes, such as Egg Beaters or Better’n Eggs, instead of whole eggs, and says it’s never too late to switch. “That’s the mistake people make, but the arteries can actually improve,” he said.

No funding source for the study was reported. Dr. Ur and Dr. Spence reported having no relevant financial relationships.

In an examination of studies that included nearly 50,000 participants, the current prevalence of mental health disorders among people experiencing homelessness was 67% and the lifetime prevalence was 77%.

“The relationship is likely bidirectional, where experiencing homelessness may exacerbate mental health symptoms or where having a mental health disorder may increase an individual’s risk for experiencing homelessness,” lead author Rebecca Barry, PhD, a postdoctoral fellow at the University of Calgary in Calgary, Alberta, Canada, told this news organization. 

“There are also likely stressors that increase both risk for homelessness and risk for developing mental health disorders. This study examines prevalence but does not examine causal relationships,” she said.

The findings were published in JAMA Psychiatry.
 

A Growing Problem 

To determine the current and lifetime prevalence of mental health disorders among the homeless population, the researchers analyzed 85 studies that examined this question in participants aged ≥ 18 years. The review included 48,414 participants, including 11,154 (23%) women and 37,260 (77%) men.

The lifetime prevalence of mental health disorders was significantly higher in men experiencing homelessness (86%) than in women (69%). The most common mental health disorder was substance use disorder (44%), followed by antisocial personality disorder (26%), major depression (19%), bipolar disorder (8%), and schizophrenia (7%).

The prevalence of current and lifetime mental health disorders among the homeless population was higher than that that observed in the general population (13%-15% and 12%-47%, respectively).

The results resembled those of a previous review that estimated that 76% of people experiencing homelessness living in high-income countries have mental health disorders.

“Even though our results are not surprising, they still are drawing attention to this issue because it is a big problem in Canada, the United States, Europe, and other places,” senior author Dallas Seitz, MD, PhD, professor of psychiatry at the University of Calgary’s Cumming School of Medicine, told this news organization. “The problem is concerning, and it’s not getting better. Addiction and mental health problems are becoming more common among people who are homeless.” 

The bottom line is that people need affordable housing and mental health support, said Dr. Seitz. “It’s a housing problem and a health problem, and we need adequate resources to find better ways for those two systems to collaborate. There are public safety concerns, and we have to try and bring services to people experiencing homelessness. You have to come and meet people where they’re at. You have to try and establish a trusting relationship so that we can get people on the path to recovery.”
 

‘It’s Really About Income’ 

Commenting on the findings for this news organization, Stephen Hwang, MD, professor of medicine at the University of Toronto, Toronto, Ontario, Canada, said, “There have been previous studies of this type, but it is good to have an updated one.” Dr. Hwang, who is also chair in Homelessness, Housing, and Health at St. Michael’s Hospital, did not participate in the research. 

The findings must be understood in the proper context, he added. For one thing, grouping together all mental health disorders and giving a single prevalence figure can be misleading. “They are including in that category a diverse group of conditions. Substance use disorder, personality disorder, schizophrenia, and depression are all lumped together. The 67% prevalence seems very high, but it is a combination of many different conditions. I just don’t want people to look at that number and think that this means that everyone is a substance user or everyone has schizophrenia,” said Dr. Hwang. 

Also, some readers might interpret the findings to mean that mental problems are the reason people are homeless, he added. “That would be an incorrect interpretation because what this study is showing is that people with mental health disorders have a higher risk for becoming homeless. It doesn’t mean that it caused their homelessness. What really causes homelessness is a lack of affordable housing,” said Dr. Hwang.

“In a city or community where housing is very expensive, there’s not enough for everyone to be housed, there is a lot of competition for housing, and there’s not enough affordable housing for a number of reasons, we know that people with mental health conditions and substance use disorders will be among the first to lose their housing,” he said.

“It’s really about income. There are many reasons why a person cannot afford housing. So, not being able to earn enough money to afford it because you have a mental health disorder or substance use disorder is a common underlying reason for homelessness.”

Dr. Hwang also pointed out that people with mental illness who can access support, either through family members or through mental health care, and who also have the income to afford such services do not become homeless.

“Schizophrenia is seen in every population of the world at a rate of 1%. But you travel to certain cities and you see people who appear to have schizophrenia wandering the streets, and you go to other cities in the world and you don’t see anyone who looks like they’re homeless and have schizophrenia,” he said. 

“It’s not because there are fewer people with schizophrenia in those cities or countries; it’s because people with schizophrenia are treated differently. The rate of homelessness is determined not by how many people have that condition [eg, schizophrenia] but by how we treat those people and how we set up our society to either support or not support people who have disabilities.”

The study was funded by the Precision Care With Information, Science and Experience – Mental Health grant funded by the Calgary Health Foundation. Dr. Barry is supported by the Harley Hotchkiss Samuel Weiss Postdoctoral Fellowship awarded by the Hotchkiss Brain Institute at the University of Calgary. Dr. Barry reported having no relevant financial relationships. Dr. Seitz reported grants from Calgary Health Foundation during the conduct of the study as well as grants from University Health Foundation, the Canadian Institutes of Health Research, the Public Health Agency of Canada, the Alzheimer’s Association, and the Hotchkiss Brain Institute. He received honoraria for guideline development from the Canadian Coalition for Seniors Mental Health outside the submitted work. Dr. Hwang reported no relevant financial relationships.

Primary care physicians who served marginalized communities had the highest proportion of patients who were unvaccinated against COVID-19, Canadian data suggested.

A study of more than 9000 family physicians in Ontario also found that the physicians with the largest proportion of unvaccinated patients were more likely to be male, to have trained outside Canada, to be older, and to work in an enhanced fee-for-service model than their counterparts who had lower proportions of unvaccinated patients.

“The family physicians with the most unvaccinated patients were also more likely to be solo practitioners and less likely to practice in team-based models, meaning they may have fewer support staff in their clinics,” lead author Jennifer Shuldiner, PhD, a scientist at Women’s College Hospital in Toronto, Ontario, Canada, told this news organization.

The findings were published in CMAJ.
 

Need vs Resources

Dr. Shuldiner and her team had been working on a project to provide additional support to family physicians with large numbers of patients who had not received their COVID-19 vaccinations. Their goal was to encourage family physicians to support these patients in getting vaccinated.

“As we were designing this project, we wondered how these physicians and their patients might differ. What characteristics might they have that would enable us to design and implement an intervention with high uptake and impact?” she said.

The researchers conducted a cross-sectional, population-based cohort study using linked administrative datasets in Ontario. They calculated the percentage of patients unvaccinated against SARS-CoV-2 who were enrolled with each comprehensive care family physician, ranked physicians according to the proportion of unvaccinated patients, and identified 906 physicians in the top 10% of unvaccinated patients. These physicians were compared with the remaining 90% of family physicians.

The physicians with the highest proportion of unvaccinated patients cared for 259,130 unvaccinated patients as of November 1, 2021. The proportion of patients who received two or more doses of the SARS-CoV-2 vaccine in this group was 74.2%. In comparison, the proportion of patients who received two or more doses of the vaccine was 87.0% in the remaining 90% of physicians.

Physicians with the largest proportion of unvaccinated patients were more likely to be male (64.6% vs 48.1%), to have trained outside Canada (46.9% vs 29.3%), to be older (mean age, 56 years vs 49 years), and to work in an enhanced fee-for-service model (49% vs 28%).

The study also found that patients enrolled with physicians in the most unvaccinated group tended to live in places with more ethnic diversity, higher material deprivation, and lower incomes. The proportion of recent immigrants was higher in this group.

“Clinics or practices with a large number of unvaccinated patients could be viable targets for efforts to coordinate public health and primary care,” said Dr. Shuldiner.

The findings indicate “the ongoing inverse relationship between the need for care and its accessibility and utilization. In other words, the practices with the highest need receive the fewest resources,” she noted.

“We know that relationships with trusted family physicians can positively influence patients’ decisions. Our study highlights the need to create equitable systems and processes that create opportunities for primary care teams to play a crucial role in influencing general and COVID-19-specific vaccine-related decision-making.”
 

Helping Primary Care Physicians

Commenting on the study for this news organization, Sabrina Wong, RN, PhD, professor of nursing at the University of British Columbia in Vancouver, British Columbia, Canada, said, “They did quite a nice analysis to show this using administrative data, and I think the information they’ve uncovered will be helpful in trying to fill the gaps and provide these practitioners with more support.”

Dr. Wong did not participate in the study. “The information they provide will be useful in helping us to move forward working with underserved, underresourced communities and also hopefully provide the clinicians, family physicians, and nurse practitioners working in these areas with more resources,” she said.

“The authors also point out that there needs to be more collaboration between public health and primary care to support these communities in their efforts to get the vaccines to the people in these communities who need them.”

The prevalence of dementia among homeless people is almost twice as high as that in housed populations in Ontario, Canada, according to the results of a new study.

The findings suggested that dementia occurs earlier in homeless individuals, and that these patients could benefit from proactive screening and housing interventions.

“Whether dementia caused the homelessness or homelessness caused the dementia, it’s a bidirectional relationship,” said lead author Richard G. Booth, PhD, RN, adjunct scientist at ICES (formerly Institute for Clinical Evaluative Sciences) and associate professor of nursing at Western University in London, Ontario, Canada.

The study was published in the April issue of The Lancet Public Health.

 

Dementia at Early Ages

The investigators used health administrative data from Ontario to compare the prevalence of dementia among homeless people with that among housed individuals in the general population and those living in low-income neighborhoods.

They included individuals aged 45 years or older on January 1, 2019, who visited hospital-based ambulatory care (such as emergency departments), were hospitalized, or visited a community health center in 2019. The researchers identified people as experiencing homelessness if they had one or more healthcare records with an indication of homelessness or unstable housing. The prevalence of dementia was ascertained as of December 31, 2019.

Included in the population-based, cross-sectional comparative analysis were 12,863 homeless people, 475,544 people in the low-income group, and 2,273,068 people in the general population group.

Dementia prevalence was 68.7 per 1000 individuals among the homeless population, 62.6 per 1000 in the low-income group, and 51.0 per 1000 in the general population group.

After adjustments for age, sex, geographical location of residence (urban vs rural), and health conditions associated with dementia, the prevalence ratio of dementia among homeless people was 1.71, compared with the low-income group, and 1.90, compared with the general population group.

Dementia also was detected in the 45- to 55-year age group among homeless people. This age is much earlier than the age at which doctors start screening their patients for cognitive decline (65 years).

“The study was not designed to define the causality but consider: If you have early-stage dementia and you are not intact enough to do basic functions of life, the likelihood of you becoming homeless is definitely increased, and vice versa. If you are homeless and suffer significant environmental and physical traumas just living on the street, you age much quicker, and you will experience geriatric symptoms such as dementia earlier in your life trajectory,” said Dr. Booth.

“The main takeaway here is that if you don’t have housing, bad things are going to happen in life.”
 

Public Health Problem

In an accompanying editorial, William J. Panenka, MD, associate professor of psychiatry at the University of British Columbia in Vancouver, British Columbia, Canada, and colleagues cited modifiable risk factors for dementia, including lower education, traumatic brain injury, substance use, smoking, mood disorders, and social isolation, many of which are disproportionately prevalent among homeless individuals.

“Ultimately, dementia could contribute to the cycle of homelessness, whereby housing instability increases the risk for brain impairment, and brain impairment makes breaking the cycle of homelessness progressively more challenging,” they wrote.

Dr. Panenka and colleagues also pointed out that the average age of homeless people is increasing. In the United States, it is now approximately 50 years. This fact underscores “the immediacy and gravity of the public health problem. A multifaceted approach that integrates healthcare, housing, and social services is needed to better understand and alleviate the health consequences of homelessness. A concerted effort at all levels is vital to inform future public health efforts and stem the tide of increasing morbidity, compromised function, and early mortality in homelessness,” they concluded.

Stephen Hwang, MD, director of the MAP Centre for Urban Health Solutions at St. Michael’s Hospital and Unity Health in Toronto, said that the study may underestimate the magnitude of the problem of dementia among homeless people.

“The methods used in this research study are very strong because they draw upon data for everyone living in the entire province of Ontario, and this is a very powerful way of looking at this challenging problem. The study probably underestimates the magnitude of the problem because to be diagnosed with dementia, patients have to have contact with healthcare providers that make that diagnosis. Often, people experiencing homelessness don’t have extensive contact with the healthcare system, and so their condition may go undiagnosed,” said Dr. Hwang.

A specialist in internal medicine, Dr. Hwang has provided healthcare for homeless people, and his research focuses on homelessness, housing, and health. He said that the findings from the Canadian study are applicable to the United States.

Forced clearances of homeless people and placing them in encampments, something that has been discussed in Florida, is unlikely to solve the problem, he said.

“The approach that has been shown to be beneficial is to engage with people and offer them housing and services that will allow them to exit homelessness without criminalizing the fact that they’re homeless. There really is no reason to think that this approach of forced clearances is going to help anyone.”

This study was supported by ICES (formerly the Institute for Clinical Evaluative Sciences), which is funded by the Ontario Ministry of Health and Ontario Ministry of Long-Term Care. Dr. Booth and Dr. Hwang reported no relevant financial relationships. Dr. Panenka reported receiving a research grant from the Canadian Institutes of Health Research.

The prevalence of dementia among homeless people is almost twice as high as that in housed populations in Ontario, Canada, according to the results of a new study.

The findings suggested that dementia occurs earlier in homeless individuals, and that these patients could benefit from proactive screening and housing interventions.

“Whether dementia caused the homelessness or homelessness caused the dementia, it’s a bidirectional relationship,” said lead author Richard G. Booth, PhD, RN, adjunct scientist at ICES (formerly Institute for Clinical Evaluative Sciences) and associate professor of nursing at Western University in London, Ontario, Canada.

The study was published in the April issue of The Lancet Public Health.

 

Dementia at Early Ages

The investigators used health administrative data from Ontario to compare the prevalence of dementia among homeless people with that among housed individuals in the general population and those living in low-income neighborhoods.

They included individuals aged 45 years or older on January 1, 2019, who visited hospital-based ambulatory care (such as emergency departments), were hospitalized, or visited a community health center in 2019. The researchers identified people as experiencing homelessness if they had one or more healthcare records with an indication of homelessness or unstable housing. The prevalence of dementia was ascertained as of December 31, 2019.

Included in the population-based, cross-sectional comparative analysis were 12,863 homeless people, 475,544 people in the low-income group, and 2,273,068 people in the general population group.

Dementia prevalence was 68.7 per 1000 individuals among the homeless population, 62.6 per 1000 in the low-income group, and 51.0 per 1000 in the general population group.

After adjustments for age, sex, geographical location of residence (urban vs rural), and health conditions associated with dementia, the prevalence ratio of dementia among homeless people was 1.71, compared with the low-income group, and 1.90, compared with the general population group.

Dementia also was detected in the 45- to 55-year age group among homeless people. This age is much earlier than the age at which doctors start screening their patients for cognitive decline (65 years).

“The study was not designed to define the causality but consider: If you have early-stage dementia and you are not intact enough to do basic functions of life, the likelihood of you becoming homeless is definitely increased, and vice versa. If you are homeless and suffer significant environmental and physical traumas just living on the street, you age much quicker, and you will experience geriatric symptoms such as dementia earlier in your life trajectory,” said Dr. Booth.

“The main takeaway here is that if you don’t have housing, bad things are going to happen in life.”
 

Public Health Problem

In an accompanying editorial, William J. Panenka, MD, associate professor of psychiatry at the University of British Columbia in Vancouver, British Columbia, Canada, and colleagues cited modifiable risk factors for dementia, including lower education, traumatic brain injury, substance use, smoking, mood disorders, and social isolation, many of which are disproportionately prevalent among homeless individuals.

“Ultimately, dementia could contribute to the cycle of homelessness, whereby housing instability increases the risk for brain impairment, and brain impairment makes breaking the cycle of homelessness progressively more challenging,” they wrote.

Dr. Panenka and colleagues also pointed out that the average age of homeless people is increasing. In the United States, it is now approximately 50 years. This fact underscores “the immediacy and gravity of the public health problem. A multifaceted approach that integrates healthcare, housing, and social services is needed to better understand and alleviate the health consequences of homelessness. A concerted effort at all levels is vital to inform future public health efforts and stem the tide of increasing morbidity, compromised function, and early mortality in homelessness,” they concluded.

Stephen Hwang, MD, director of the MAP Centre for Urban Health Solutions at St. Michael’s Hospital and Unity Health in Toronto, said that the study may underestimate the magnitude of the problem of dementia among homeless people.

“The methods used in this research study are very strong because they draw upon data for everyone living in the entire province of Ontario, and this is a very powerful way of looking at this challenging problem. The study probably underestimates the magnitude of the problem because to be diagnosed with dementia, patients have to have contact with healthcare providers that make that diagnosis. Often, people experiencing homelessness don’t have extensive contact with the healthcare system, and so their condition may go undiagnosed,” said Dr. Hwang.

Sublingual immunotherapy (SLIT) is as safe and effective for high-risk older children and adolescents as oral immunotherapy (OIT) is for infants and preschoolers, according to new research.

Preliminary data from a study of more than 180 pediatric patients with multiple food allergies showed that while most patients had mild symptoms, none experienced a severe grade 4 reaction during the buildup and maintenance phase of SLIT.

In addition, 70% of those tested at the end of the treatment protocol were able to tolerate 300 mg of their allergen, a success rate nearly as high as that for OIT.

The study was published in The Journal of Allergy and Clinical Immunology: In Practice.

SLIT has been used successfully in the treatment of environmental allergens such as grass and tree pollen and dust mites. In this study, researchers decided to test SLIT’s effectiveness and safety in the treatment of food allergies in older children.

“We knew that OIT is very effective and safe in infants and toddlers, but there was literature illustrating that for older, school-age kids and adolescents, OIT is not safe enough, as those older age groups tend to have higher risk of severe reaction during treatment,” senior author Edmond Chan, MD, clinical professor of allergy at the University of British Columbia and pediatric allergist at BC Children’s Hospital, both in Vancouver, British Columbia, Canada, told this news organization. “With that knowledge, we decided to explore SLIT as another first-phase therapy for the older kids.”

The investigators recruited 188 high-risk older children aged 4-18 years for multifood SLIT. Most (61.7%) participants had multiple food allergies. Approximately 68% were male, and the population’s median age was 11.3 years.

Nearly half (48.4%) of participants had atopic dermatitis, 45.2% had asthma, 58.0% had allergic rhinitis, and 2.66% had preexisting eosinophilic esophagitis.

Most (75.0%) of the children were classified as higher risk, and 23 had a history of a grade 3 or 4 reaction before beginning SLIT.

Of the 188 children who were initially enrolled in the study, 173 (92.0%) finished their SLIT buildup phase.

Because the study started when COVID-19 pandemic restrictions were in place, the SLIT protocol mandated that patients be seen virtually. The patients’ caregivers learned how to mix and administer the required doses at home using recipes specially developed by the research team that used products bought at the grocery store.

A wide variety of food allergens were treated, including peanut, other legumes, tree nuts, sesame, other seeds, egg, cow’s milk, fish, wheat, shrimp, and other allergens.

The children built up to 2-mg protein SLIT maintenance over the course of three to five visits under nurse supervision.

After 1-2 years of daily SLIT maintenance, patients were offered a low-dose oral food challenge (OFC; cumulative dose: 300 mg of protein) with the goal of bypassing OIT buildup.

Nearly all patients (93.1%) had symptoms during SLIT buildup, but most were mild grade 1 (52.1%) or 2 (40.4%) reactions. Only one patient had a grade 3 reaction. None of the patients experienced a severe grade 4 reaction.

The most common grade 1 reaction was oral itch, an expected symptom of SLIT, which occurred in 82.7% of the patients.

Four patients (2.10%) received epinephrine during buildup and went to the emergency department. All these patients returned to continue SLIT without further need for epinephrine.

To test the effectiveness of SLIT, the researchers performed 50 low-dose OFCs in 20 patients. Of these food challenges, 35 (70%) were successful, and patients were asked to start daily 300-mg OIT maintenance, thus bypassing OIT buildup.

An additional nine OFCs that were unsuccessful were counseled to self-escalate from 80 mg or higher to 300 mg at home with medical guidance as needed.

“Our preliminary data of 20 patients and 50 low-dose oral food challenges suggest that an initial phase of 1-2 years of 2-mg daily SLIT therapy may be a safe and effective way to bypass the OIT buildup phase without the need for dozens of in-person visits with an allergist,” said Dr. Chan.

“So now we have the best of both worlds. We harness the safety of SLIT for the first 1-2 years, with the effectiveness of OIT for the remainder of the treatment period,” he said.
 

Adds to Evidence

Commenting on the study for this news organization, Julia Upton, MD, associate professor of pediatrics at the University of Toronto, Toronto, Ontario, Canada, said, “This study adds to the evidence that consistent, low exposure to food drives meaningful desensitization far above the daily dose.” Upton did not participate in the research.

“Prior prospective studies in SLIT demonstrated that small single-digit-milligram doses and time greatly increased the threshold of reaction. This real-world report suggests that a way to utilize that threshold increase is by switching to a commonly used maintenance dose of OIT,” said Dr. Upton.

“Although few patients have been assessed for the 300-mg challenge, this study is notable for the age group of 4-18 years, and that many of the patients had reacted to low doses in the past. It also shows that many families are capable of diluting and mixing their own immunotherapy solutions with store-bought foods under the guidance of an experienced allergy clinic,” she added.

“Overall, evidence is building that by various routes, initial small amounts with minimal updoses, plus the tincture of time, may be preferred to multiple frequent updosing from multiple perspectives, including safety, feasibility, cost, and medical resources. It will also be important to understand the preferences and goals of the patient and family as various regimens become more available,” Dr. Upton concluded.

The study was funded by BC Children’s Hospital Foundation. Dr. Chan reported receiving research support from DVB Technologies; has been a member of advisory boards for Pfizer, Miravo, Medexus, Leo Pharma, Kaleo, DBV, AllerGenis, Sanofi, Genzyme, Bausch Health, Avir Pharma, AstraZeneca, ALK, and Alladapt; and was a colead of the CSACI OIT guidelines. Dr. Upton reported research support/grants from Novartis, Regeneron, Sanofi, ALK Abello, DBV Technologies, CIHR, and SickKids Food Allergy and Anaphylaxis Program and fees from Pfizer, ALK Abello, Bausch Health, Astra Zeneca, and Pharming.

Healthcare workers have been at an increased risk for SARS-CoV-2 infection and mental distress such as anxiety and depression during the pandemic, according to new research.

In an analysis of administrative health records for about 3000 healthcare workers in Alberta, Canada, the workers were as much as twice as likely to become infected with SARS-CoV-2 compared with the overall population. The risk for infection was higher among healthcare workers in the first two waves of the pandemic and again during the fifth wave.

“Previous publications, including ours, suggested that the main problem was in the early weeks and months of the pandemic, but this paper shows that it continued until the later stages,” senior author Nicola Cherry, MD, an occupational epidemiologist at the University of Alberta in Edmonton, Canada, told this news organization.

The findings were published in the Canadian Journal of Public Health.
 

Wave Upon Wave

In the current study, the investigators sought to compare the risk for SARS-CoV-2 infection and mental distress among healthcare workers and among community referents (CRs). They examined the following waves of the COVID-19 pandemic:

• Wave 1: From March to June 2020 (4 months).
• Wave 2: From July 2020 to February 2021 (8 months).
• Wave 3: From March to June 2021 (4 months).
• Wave 4: From July to October 2021 (4 months).
• Wave 5 (Omicron): From November 2021 to March 2022 (5 months).

Healthcare workers in Alberta were asked at recruitment for consent to match their individual records to the Alberta Administrative Health Database. As the pandemic progressed, participants were also asked for consent to be linked to COVID-19 immunization records maintained by the provinces, as well as for the results of all polymerase chain reaction (PCR) testing for the SARS-CoV-2 virus.

The investigators matched 2959 healthcare workers to 14,546 CRs according to their age, sex, geographic location in Alberta, and number of physician claims from April 1, 2019, to March 31, 2020.

Incident SARS-CoV-2 infection was examined using PCR testing and the first date of a physician consultation at which the code for SARS-CoV-2 infection had been recorded. Mental health disorders were identified from physician records. They included anxiety disorders, stress and adjustment reactions, and depressive disorders.

Most (79.5%) of the healthcare workers were registered nurses, followed by physicians (16.1%), healthcare aides (2.4%), and licensed practical nurses (2.0%). Most participants (87.5%) were female. The median age at recruitment was 44 years.

Healthcare workers were at a greater risk for COVID-19 overall, with the first SARS-CoV-2 infection defined from either PCR tests (odds ratio [OR], 1.96) or from physician records (OR, 1.33). They were also at an increased risk for anxiety (adjusted OR, 1.25; P < .001), stress/adjustment reaction (adjusted OR, 1.52; P < .001), and depressive condition (adjusted OR, 1.39; P < .001). Moreover, the excess risks for stress/adjustment reactions and depressive conditions increased with successive waves during the pandemic, peaking in the fourth wave and continuing in the fifth wave.

“Although the increase was less in the middle of the phases of the pandemic, it came back with a vengeance during the last phase, which was the Omicron phase,” said Dr. Cherry.

“Employers of healthcare workers can’t assume that everything is now under control, that they know what they’re doing, and that there is no risk. We are now having some increases in COVID. It’s going to go on. The pandemic is not over in that sense, and infection control continues to be major,” she added.

The finding that mental health worsened among healthcare workers was not surprising, Dr. Cherry said. Even before the pandemic, studies had shown that healthcare workers were at a greater risk for depression than the population overall.

“There is a lot of need for care in mental health support of healthcare workers, whether during a pandemic or not,” said Dr. Cherry.
 

Nurses Are Suffering

Commenting on the research for this news organization, Farinaz Havaei, PhD, RN, assistant professor of nursing at the University of British Columbia in Vancouver, Canada, said, “This is a very important and timely study that draws on objective clinical and administrative data, as opposed to healthcare workers’ subjective reports.” Dr. Havaei did not participate in the research.

Overall, the findings are consistent with previous research that drew upon healthcare workers’ reports. They speak to the chronic and cumulative impact of COVID-19 and its associated stressors on the mental health and well-being of healthcare workers, said Dr. Havaei.

“The likelihood of stress/adjustment reaction and depression showed a relatively steady increase with increasing COVID-19 waves. This increase can likely be explained by healthcare workers’ depleting emotional reserves for coping with chronic workplace stressors such as concerns about exposure to COVID-19, inadequate staffing, and work overload,” she said. Witnessing the suffering and trauma of patients and their families likely added to this risk.

Dr. Havaei also pointed out that most of the study participants were nurses. The findings are consistent with prepandemic research that showed that the suboptimal conditions that nurses increasingly faced resulted in high levels of exhaustion and burnout.

“While I agree with the authors’ call for more mental health support for healthcare workers, I think prevention efforts that address the root cause of the problem should be prioritized,” she said.
 

From Heroes to Zeros

The same phenomena have been observed in the United States, said John Q. Young, MD, MPP, PhD, professor and chair of psychiatry at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell in Hempstead, New York. In various studies, Dr. Young and his colleagues have reported a strong association between exposure to the stressors of the pandemic and subsequent development of depression, anxiety, and posttraumatic stress disorder (PTSD) among healthcare workers.

“The findings from Alberta are remarkably consistent. In the beginning of the pandemic, there was a lot of acknowledgment of the work healthcare workers were doing. The fire department clapping as you leave work at night, being called heroes, even though a lot of healthcare workers feel uncomfortable with the hero language because they don’t feel like heroes. Yes, they’re afraid, but they are going to do what they need to do and help,” he said.

But as the pandemic continued, public sentiment changed, Dr. Young said. “They’ve gone from heroes to zeros. Now we are seeing the accumulated, chronic effects over months and years, and these are significant. Our healthcare workforce is vulnerable now. The reserves are low. There are serious shortages in nursing, with more retirements and more people leaving the field,” he said.

As part of a campaign to help healthcare workers cope, psychiatrists at Northwell Health have started a program called Stress First Aid at their Center for Traumatic Stress Response Resilience, where they train nurses, physicians, and other healthcare staff to use basic tools to recognize and respond to stress and distress in themselves and in their colleagues, said Dr. Young.

“For those healthcare workers who find that they are struggling and need more support, there is resilience coaching, which is one-on-one support. For those who need more clinical attention, there is a clinical program where our healthcare workers can meet with a psychologist, psychiatrist, or a therapist, to work through depression, PTSD, and anxiety. We didn’t have this before the pandemic, but it is now a big focus for our workforce,” he said. “We are trying to build resilience. The trauma is real.”

The study was supported by the College of Physicians and Surgeons of Alberta, the Canadian Institutes of Health Research, and the Canadian Immunology Task Force. Dr. Cherry and Dr. Havaei reported no relevant financial relationships. Dr. Young reported that he is senior vice president of behavioral health at Northwell.

Healthcare workers have been at an increased risk for SARS-CoV-2 infection and mental distress such as anxiety and depression during the pandemic, according to new research.

In an analysis of administrative health records for about 3000 healthcare workers in Alberta, Canada, the workers were as much as twice as likely to become infected with SARS-CoV-2 compared with the overall population. The risk for infection was higher among healthcare workers in the first two waves of the pandemic and again during the fifth wave.

“Previous publications, including ours, suggested that the main problem was in the early weeks and months of the pandemic, but this paper shows that it continued until the later stages,” senior author Nicola Cherry, MD, an occupational epidemiologist at the University of Alberta in Edmonton, Canada, told this news organization.

The findings were published in the Canadian Journal of Public Health.
 

Wave Upon Wave

In the current study, the investigators sought to compare the risk for SARS-CoV-2 infection and mental distress among healthcare workers and among community referents (CRs). They examined the following waves of the COVID-19 pandemic:

• Wave 1: From March to June 2020 (4 months).
• Wave 2: From July 2020 to February 2021 (8 months).
• Wave 3: From March to June 2021 (4 months).
• Wave 4: From July to October 2021 (4 months).
• Wave 5 (Omicron): From November 2021 to March 2022 (5 months).

Healthcare workers in Alberta were asked at recruitment for consent to match their individual records to the Alberta Administrative Health Database. As the pandemic progressed, participants were also asked for consent to be linked to COVID-19 immunization records maintained by the provinces, as well as for the results of all polymerase chain reaction (PCR) testing for the SARS-CoV-2 virus.

The investigators matched 2959 healthcare workers to 14,546 CRs according to their age, sex, geographic location in Alberta, and number of physician claims from April 1, 2019, to March 31, 2020.

Incident SARS-CoV-2 infection was examined using PCR testing and the first date of a physician consultation at which the code for SARS-CoV-2 infection had been recorded. Mental health disorders were identified from physician records. They included anxiety disorders, stress and adjustment reactions, and depressive disorders.

Most (79.5%) of the healthcare workers were registered nurses, followed by physicians (16.1%), healthcare aides (2.4%), and licensed practical nurses (2.0%). Most participants (87.5%) were female. The median age at recruitment was 44 years.
