Understanding the mental health and intention to leave of the public health workforce in Canada during the COVID-19 pandemic: A cross-sectional study.

BACKGROUND: There is limited evidence about the mental health and intention to leave of the public health workforce in Canada during the COVID-19 pandemic. The objectives of this study were to determine the prevalence of burnout, symptoms of anxiety and depression, and intention to leave among the Canadian public health workforce, and associations with individual and workplace factors. METHODS: A cross-sectional study was conducted using data collected by a Canada-wide survey from November 2022 to January 2023, where participants reported sociodemographic and workplace factors. Mental health outcomes were measured using validated tools including the Oldenburg Burnout Inventory, the 7-item Generalized Anxiety Disorder scale, and the 2-item Patient Health Questionnaire to measure symptoms of depression. Participants were asked to report if they intended to leave their position in public health. Logistic regression was used to estimate adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) for the associations between explanatory variables such as sociodemographic, workplace factors, and outcomes of mental health, and intention to leave public health. RESULTS: Among the 671 participants, the prevalence of burnout, and symptoms of depression and anxiety in the two weeks prior were 64%, 26%, and 22% respectively. 33% of participants reported they were intending to leave their public health position in the coming year. Across all outcomes, sociodemographic factors were largely not associated with mental health and intention to leave. However, an exception to this was that those with 16-20 years of work experience had higher odds of burnout (aOR = 2.16; 95% CI = 1.12-4.18) compared to those with ≤ 5 years of work experience. Many workplace factors were associated with mental health outcomes and intention to leave public health. Those who felt bullied, threatened, or harassed because of work had increased odds of depressive symptoms (aOR = 1.85; 95% CI = 1.28-2.68), burnout (aOR = 1.61; 95% CI = 1.16-2.23), and intention to leave (aOR = 1.64; 95% CI = 1.13-2.37). CONCLUSIONS: During the COVID-19 pandemic, some of the public health workforce experienced negative impacts on their mental health. 33% of the sample indicated an intention to leave their role, which has the potential to exacerbate pre-existing challenges in workforce retention. Study findings create an impetus for policy and practice changes to mitigate risks to mental health and attrition to create safe and healthy working environments for public health workers during public health crises.

Incorporating equity, diversity, and inclusion into the epidemiology and biostatistics curriculum: A workshop report and implementation strategies recommendations.

There is an obligation among those teaching epidemiology to incorporate principles of equity, diversity, and inclusion (EDI) into the curriculum. While there is a well-established literature related to teaching epidemiology, this literature rarely addresses critical aspects of EDI. To our knowledge, there is no working group or central point of discussion and learning for incorporating EDI into epidemiology teaching in Canada. To address this gap, we convened a workshop entitled "Incorporating EDI into the epidemiology and biostatistics curriculum and classroom." The workshop discussed nine strategies to incorporate EDI in the epidemiology curriculum: positionality (or reflexivity) statements; opportunities for feedback; land acknowledgements; clarifying the purpose of collecting data on race and ethnicity, sex and gender, Indigeneity; acknowledging that race/ethnicity is a social construct, not a biological variable; describing incidence and prevalence of disease; demonstrating explicit bias using directed acyclic graphs (DAGs); critical appraisal of study population diversity; and admission criteria and considerations. Key take-aways from the workshop were the need to be more intentional when determining the validity of evidence, particularly with respect to historical context and the need to recognize that there is no single solution that will address EDI.

RéSUMé: Les personnes qui enseignent l'épidémiologie ont l'obligation d'intégrer les principes d'équité, de diversité et d'inclusion (EDI) dans le programme d'études. Bien qu'il existe une littérature bien établie sur l'enseignement de l'épidémiologie, cette littérature aborde rarement les aspects critiques de l'EDI. À notre connaissance, il n'existe pas de groupe de travail ou de point central de discussion et d'apprentissage pour l'intégration de l'EDI dans l'enseignement de l'épidémiologie au Canada. Pour combler cette lacune, nous avons organisé un atelier intitulé « Incorporer l'EDI dans le programme d'enseignement de l'épidémiologie et de la biostatistique et dans la salle de classe ¼. L'atelier a examiné neuf stratégies visant à intégrer l'EDI dans le programme d'enseignement de l'épidémiologie : déclarations de positionnement (ou de réflexivité); occasions pour partager de la rétroaction; reconnaissances territoriales; clarification de l'objectif derrière la collecte de données sur la race et l'ethnicité, le sexe et le genre et l'indigénéité; reconnaissance du fait que la race/l'ethnicité est une construction sociale et non une variable biologique; description de l'incidence et de la prévalence des maladies; démonstration de parti pris explicites à l'aide de graphe orienté acyclique (DAG); évaluation critique de la diversité de l'échantillon étudié; et critères et considérations d'admission. Les principaux enseignements tirés de l'atelier sont la nécessité d'être plus intentionnel dans la détermination de la validité des données probantes, en particulier en ce qui concerne le contexte historique, et la nécessité de reconnaître qu'il n'existe pas de solution unique pour prendre en compte les principes de l'EDI.

Front row seat: The role MMI assessors play in widening access to medical school.

BACKGROUND: While many medical schools utilize the Multiple Mini-Interview (MMI) to help select a diverse student body, we know little about MMI assessors' roles. Do MMI assessors carry unique insights on widening access (WA) to medical school? Herein we discuss the hidden expertise and insights that assessors contribute to the conversation around WA. METHODS: Ten MMI assessors (1-10 years' experience) participated in semi-structured interviews exploring factors influencing equitable medical school recruitment. Given their thoughtfulness during initial interviews, we invited them for follow-up interviews to gain further insight into their perceived role in WA. Fourteen interviews were conducted and analyzed using a thematic analysis approach. RESULTS: Assessors expressed concerns with diversity in medicine; dissatisfaction with the status quo fueled their contributions to the selection process. Assessors advocated for greater diversity among the assessor pool, citing benefits for all students, not only those from underrepresented groups. They noted that good intentions were not enough and that medical schools can do more to include underrepresented groups' perspectives in the admissions process. CONCLUSION: Our analysis reveals that MMI assessors are committed to WA and make thoughtful contributions to the selection process. A medical school selection process, inclusive of assessors' expertise is an important step in WA.

Investigation of the first cases of human-to-human infection with the new swine-origin influenza A (H1N1) virus in Canada.

The outbreak of human infection due to the novel swine-origin influenza A (H1N1) virus began in Mexico in March 2009. As of July 6, 2009, more than 94,000 laboratory-confirmed cases were reported in over 100 countries, including 7983 cases in Canada. In this report, we describe the epidemiologic and clinical characteristics of the first cluster of reported cases of human-to-human transmission of the new influenza virus in Canada.

Two successive outbreaks of mumps in Nova Scotia among vaccinated adolescents and young adults.

BACKGROUND: Before the widespread use of vaccine, mumps was the most common cause of viral meningitis (up to 10% of mumps infections). Vaccination programs have resulted in a drop of more than 99% in the number of reported mumps cases in the United States and Canada. Although rare in Canada, outbreaks have recently occurred throughout the world, including a large outbreak in the United Kingdom, where more than 56,000 cases were reported in 2004-2005. METHODS: Two recent outbreaks in Nova Scotia were investigated by public health officials. Cases were defined by laboratory confirmation of infection (i.e., isolation of mumps virus by culture) or clinical diagnosis in people epidemiologically linked to a laboratory-confirmed case. The people infected were interviewed to determine possible links and to identify contacts. Mumps virus was cultured from urine and throat specimens, identified via reverse-transcriptase polymerase chain reaction (RT-PCR) and subjected to phylogenetic analysis to identify the origin of the strain. RESULTS: The first outbreak involved 13 high-school students (median age 14 yr): 9 who had previously received 2 doses of measles-mumps-rubella vaccine (MMR) and 4 who received a single dose. The second outbreak comprised 19 cases of mumps among students and some staff at a local university (median age 23 yr), of whom 18 had received only 1 dose of MMR (the other received a second dose). The viruses identified in the outbreaks were phylogenetically similar and belonged to a genotype commonly reported in the UK. The virus from the second outbreak is identical to the strain currently circulating in the UK and United States. INTERPRETATION: The predominance in these outbreaks of infected people of university age not only highlights an environment with potential for increased transmission but also raises questions about the efficacy of the MMR vaccine. The people affected may represent a "lost cohort" who do not have immunity from natural mumps infection and were not offered a 2-dose schedule. Given the current level of mumps activity around the world, clinicians should remain vigilant for symptoms of mumps.
