Women are under-represented in senior roles within academic medicine, including as authors in high-impact journals. To examine trends and predictors of female authorship in the Canadian Medical Association Journal (CMAJ) as the only high-impact Canadian journal over a 10-year period to understand gender balances in Canadian academic publishing. This cross-sectional study analysed trends and predictors of female authorship in articles published in CMAJ from 1 January 2013 to 31 December 2023. Data were extracted from PubMed for CMAJ, the only high-impact Canadian medical journal (impact factor ≥10). Data extraction used the RISmed package in R Studio. The study included articles published in CMAJ within the specified period. Author gender was predicted using the validated Genderize.io software. Articles where the gender of the authors could not be predicted were excluded from analysis. The co-primary outcomes were proportions of female first and last authors. Statistical analyses included χ2 tests comparing proportions, Jonckheere and linear regression models to evaluate trends. Among multiauthor articles, multivariable logistic regression models assessed predictors of female first and last authorship. From 5805 included articles, women comprised 47% of first authors and 43% of last authors (p<0.001), both significantly lower than men (p<0.001). Female first authorship increased by 17.7% and female last authorship by 10.5% over the study period (both p<0.05 for trend), reaching a majority (58%) and near parity (48%) in 2023, respectively. Female editor-in-chief and higher proportion of female coauthors were associated with higher odds of female first and last authors; female last authors were additionally associated with higher odds of female first authors. Women were under-represented in authorship overall, though female first and last authorship increased over time, with first authorship exceeding parity in recent years and last authorship nearing equal representation. Female editors-in-chief and a higher proportion of female coauthors were associated with greater female first and last authorship, while female last authorship was additionally associated with higher odds of female first authorship. These findings provide insight into authorship trends in a high-impact Canadian medical journal and may inform future efforts to support gender equity in academic publishing.
Infertility is a major public health concern, and many individuals face substantial barriers to accessing fertility care. Across jurisdictions, regulations, eligibility criteria and funding frameworks for fertility care vary considerably, particularly in relation to lesbian, gay, bisexual, transgender, intersex and queer/questioning people (LGBTIQ+), as well as unpartnered individuals. Moreover, existing definitions and prevalence estimates of infertility are largely derived from studies of heterosexual couples which may underestimate the need for fertility care among other populations. This protocol describes a systematic review designed to synthesise current evidence on the need for and access to fertility care among LGBTIQ+ populations and unpartnered individuals as well as the policies and regulations that govern such care. This protocol follows the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) guidelines. Systematic searches were conducted in MEDLINE (Ovid), Embase, Web of Science, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Global Health, as well as grey literature sources including ProQuest Dissertations & Theses, ECRI Guidelines Trust, Canadian Medical Association Journal (CMAJ) Guidelines, National Institute for Health and Care Excellence, fertility societies guidelines and Google Scholar. Eligible studies will include quantitative, qualitative, mixed-methods, narrative synthesis and typology mapping designs. Two reviewers will independently perform title/abstract and full-text screening, data extraction and quality assessment. The Critical Appraisal Skills Programme checklist will be used for qualitative studies and the Joanna Briggs Institute tools for quantitative studies. Completeness and credibility assessments will be applied to narrative syntheses and typology mappings. The primary outcomes will include measures of fertility care need, indicators of access and policy frameworks influencing service availability. This study does not involve human participants. The protocol received an exemption from Research Ethics Board review by the McGill University Health Centre Research Ethics Board. Findings will be disseminated through peer-reviewed publications, conference presentations and professional networks and shared with the WHO to inform evidence-based policy. CRD420251126056.
Cataract surgery is usually performed with topical anesthesia and sedation, which may be provided through a number of different care models with or without involvement of a physician anesthesiologist. We sought to describe anesthesiology care for cataract surgery in Ontario, Canada, and examine the association between the model of anesthesiology care and health service and perioperative outcomes after cataract surgery. We conducted a population-based study of patients who underwent cataract surgery in Ontario using linked health administrative data between 2012 and 2021. The primary outcome was a composite of death, acute hospital admission, or emergency department visit up to 7 days postoperatively. We also collected data on health system costs and operative complications (from physician billing codes). We used multilevel, multivariable regression to estimate adjusted associations between anesthesiology care - fee-for-service anesthesiology care (FFS), care from an anesthesiology care team (ACT), or no physician anesthesiologist care - and outcomes. Of 1 271 251 patients who underwent cataract surgery, 670 754 (52.8%) received FFS care, 256 760 (20.2%) received ACT care, and 343 737 (27.0%) had no physician anesthesiologist care. Adjusted analyses estimated slightly lower odds of the primary composite outcome for patients who received FFS care (n = 8682, 1.3%; adjusted odds ratio [OR] 0.93, 95% confidence interval [CI] 0.88 to 0.99) or ACT care (n = 3034, 1.2%; adjusted OR 0.83, 95% CI 0.76 to 0.89) compared with those with no physician anesthesiologist care (n = 5056, 1.5%). Odds of operative complications were lower and overall costs were higher with any type of physician-provided anesthesiology care. Primary results differed by whether care was provided in a teaching or nonteaching hospital. Care provided or overseen by a physician anesthesiologist was associated with significantly lower odds of an emergency department visit, hospital admission, or death; however, effect sizes were small and of limited clinical importance, and costs were higher. Given these findings, the use of physician anesthesiology care for routine cataract surgery should be reconsidered. Open Science Framework identifier https://osf.io/9y3mt/overview.
Although brain and heart conditions share overlapping risk factors and commonly co-occur, current cardiac and neurologic clinical guidelines are typically produced within specialty silos. The objective of this guideline from a Canadian Cardiovascular Harmonized National Guideline Endeavour (C-CHANGE) panel is to expand on current cardiovascular guidelines to include evidence from the neurologic and mental health literature, with specific recommendations for providers managing comorbid brain and heart conditions. The guideline development panel comprised an Executive Steering Committee; 10 expert subgroups to develop research questions and draft recommendations for specific brain-heart conditions; an Evidence Review Team to ensure the rigour and consistent application of the methodology; and an Implementation Committee to facilitate uptake of the recommendations by clinicians and into electronic medical records. The McMaster Evidence Review and Synthesis Team supported the literature searches and critical appraisal. A panel of people with lived experience of specific conditions and caregivers provided input on patient values and perspectives throughout the guideline development process. Our consensus process followed the Appraisal of Guidelines for Research and Evaluation II framework. We used an established evidence appraisal approach to determine the level of evidence and strength of each recommendation, and adhered to the Guidelines International Network's principles for managing competing interests. We developed 11 recommendations for the management of joint brain and heart diseases. Key recommendations include screening for cognitive decline in atrial fibrillation and depression in coronary artery disease; treatment of depression in coronary artery disease, cognitive impairment in hypertension, and dyslipidemia in stroke; and vaccination to prevent stroke, myocardial infarction, and dementia. We also recommend shared decision-making, including the use of evidence-based decision aids, to support patients with heart-brain diseases. We sought to produce an implementable and actionable guideline for patients with brain and heart comorbidity. It is primarily targeted to primary care providers, but also relevant to help address and individualize subspeciality care and for interprofessional teams caring for patients with joint brain and heart diseases.
The long-term impacts of traumatic brain injury (TBI) in older adults are not well known. Our objective was to describe the association between late-life TBI, incident dementia, and health care needs. We conducted a retrospective cohort study using linked health administrative data in Ontario, Canada, and included community-dwelling individuals older than 65 years with a new TBI between Apr. 1, 2004, and Mar. 1, 2020, and up to 17 years of follow-up. People with and without TBI were 1:1 matched on age, sex, and propensity score. We compared rates of incident dementia (≤ 5 yr and > 5 yr), use of publicly funded home care, and admission to a long-term care home, using cause-specific hazard models. We used conditional inference trees to identify subgroups at high risk for outcomes based on associations with individual and intersecting social determinants of health. We included 132 113 matched pairs. Late-life TBI was associated with an increased rate of incident dementia (≤ 5 yr: hazard ratio [HR] 1.69, 95% confidence interval [CI] 1.66 to 1.72; > 5 yr: HR 1.56, 95% CI 1.53 to 1.59), use of publicly funded home care (HR 1.30, 95% CI 1.29 to 1.31), and admission to a long-term care home (HR 1.45, 95% CI 1.42 to 1.47). Dementia was more common among older females from low-income neighbourhoods than among male peers (29.0% v. 24.7%). Residents of smaller communities received less home care than those in larger communities (60.1% v. 64.6%) and had a higher probability of long-term care home admission (26.3% v. 21.7%). Late-life TBI in community-dwelling older adults is associated with higher rates of incident dementia, use of publicly funded home care, and admission to a long-term care home, with older females and residents of smaller communities experiencing poorer outcomes. Clinical awareness and policy planning that reflects these needs and population heterogeneity are important. Open Science Framework identifier 10.17605/OSF.IO/KZT3F.
Dual antiplatelet therapy is the standard of care for acute coronary syndrome, but uncertainty exists regarding the optimal regimen for patients in North America. We sought to compare the effectiveness and safety of acetylsalicylic acid (ASA) and ticagrelor or clopidogrel in patients with acute coronary syndrome from a single tertiary academic centre in Montréal, Canada. We conducted a pragmatic, open-label, time-clustered (bimonthly between October 2018 and March 2021), randomized controlled trial. The primary effectiveness end point was a composite of all-cause mortality, nonfatal myocardial infarction, or ischemic stroke. The primary safety end point was hospital admissions for bleeding. We ascertained 12-month outcomes from the Quebec universal electronic health databases. We designed and analyzed the study within a Bayesian paradigm to supplement existing knowledge. The primary analysis was a Bayesian logistic regression model with an informed focused prior from previously randomly assigned North American patients. Robustness was evaluated with vague and other prespecified informative priors, spanning reasonable pre-existing beliefs. We defined clinically important benefits and harms as risk reductions exceeding a 10% difference. We randomly assigned 1005 patients with acute coronary syndrome to ticagrelor (n = 450) or clopidogrel (n = 555). Major acute cardiovascular events occurred in 50 (11.1%) patients assigned to ticagrelor and 64 (11.5%) assigned to clopidogrel (relative risk [RR] 0.95, 95% credible interval 0.67-1.35, with a vague prior). The primary analysis with an informed focused prior resulted in probabilities of a clinically meaningful ticagrelor benefit (RR < 0.9), equivalence (0.9 ≤ RR ≤ 1.1) or harm (RR ≥ 1.1) of 2%, 41%, and 57%, respectively. For the safety end point, there was no consistent signal of benefit or harm with ticagrelor. Sensitivity analyses with a range of prior beliefs gave generally consistent results. Whether we analyzed this trial with a vague or a range of reasonable informed priors, we found no strong evidence for the superiority of ticagrelor over clopidogrel in North American patients. Current guidelines favouring ticagrelor over clopidogrel might take this new evidence into future consideration. Clinicaltrials.gov no. NCT04057300.
Cognitive behavioural therapy (CBT) has been shown to be effective for several psychiatric and somatic conditions; however, most randomized controlled trials (RCTs) have administered treatment in person and whether remote delivery is similarly effective remains uncertain. We sought to compare the effectiveness of therapist-guided remote CBT and in-person CBT. We systematically searched MEDLINE, Embase, PsycINFO, CINAHL, and the Cochrane Central Register of Controlled Trials from inception to July 4, 2023, for RCTs that enrolled adults (aged ≥ 18 yr) presenting with any clinical condition and that randomized participants to either therapist-guided remote CBT (e.g., teleconference, videoconference) or in-person CBT. Paired reviewers assessed risk of bias and extracted data independently and in duplicate. We performed random-effects model meta-analyses to pool patient-important primary outcomes across eligible RCTs as standardized mean differences (SMDs). We used Grading of Recommendations Assessment, Development and Evaluation (GRADE) guidance to assess the certainty of evidence and used the Instrument to Assess the Credibility of Effect Modification Analyses (ICEMAN) to rate the credibility of subgroup effects. We included 54 RCTs that enrolled a total of 5463 patients. Seventeen studies focused on treatment of anxiety and related disorders, 14 on depressive symptoms, 7 on insomnia, 6 on chronic pain or fatigue syndromes, 5 on body image or eating disorders, 3 on tinnitus, 1 on alcohol use disorder, and 1 on mood and anxiety disorders. Moderate-certainty evidence showed little to no difference in the effectiveness of therapist-guided remote and in-person CBT on primary outcomes (SMD -0.02, 95% confidence interval -0.12 to 0.07). Moderate-certainty evidence showed little to no difference in the effectiveness of in-person and therapist-guided remote CBT across a range of mental health and somatic disorders, suggesting potential for the use of therapist-guided remote CBT to facilitate greater access to evidence-based care.

To determine the association of initial empiric antibiotic regimens with clinical outcomes in hospitalised children with severe orbital infections. Multi-centre observational cohort study using data from 2009 to 2018 clinical records. Canadian children's hospitals (7) and community hospitals (3). Children between 2 months and 18 years hospitalised for >24 hours with severe orbital infections. Empiric intravenous antibiotic regimen in the first 24 hours of hospitalisation. Length of hospital stay and surgical intervention using multivariable median regression and multivariate logistic regression, with adjustment for covariates. Of 1421 patients, 60.0% were male and the median age was 5.5 years (IQR 2.4-9.9). Median length of stay was 86.4 hours (IQR 56.9-137.5) and 180 (12.7%) received surgical intervention. Patients receiving broad-spectrum empiric antibiotics had an increased median length of stay, ranging from an additional 13.8 hours (third generation cephalosporin and anaerobic coverage) to 19.5 hours (third generation cephalosporin, staphylococcal and anaerobic coverage). No antibiotic regimen was associated with a change in the odds of surgical intervention. These findings remained unchanged in sensitivity analyses restricted to more severely ill patients. There was a twofold increase in the percentage of patients receiving the broadest empiric antibiotic regimens containing both staphylococcal and anaerobic coverage from 17.8% in 2009 to 40.3% in 2018. Empiric use of broad-spectrum antibiotics with staphylococci and anaerobic coverage was associated with longer length of stay and similar rates of surgery in children with orbital infections. There is an urgent need for comparative effectiveness studies of various antibiotic regimes.
The primary objective was to investigate temporal trends and between-practice variability of paediatric test use in primary care. This was a descriptive study of population-based data from Clinical Practice Research Datalink Aurum primary care consultation records from 1 January 2007 to 31 December 2019. Children aged 0-15 who were registered to one of the eligible 1464 general practices and had a diagnostic test code in their clinical record were included. The primary outcome measures were (1) temporal changes in test rates measured by the average annual percent change, stratified by test type, gender, age group and deprivation level and (2) practice variability in test use, measured by the coefficient of variation. 14 299 598 diagnostic tests were requested over 27.8 million child-years of observation for 2 542 101 children. Overall test use increased by 3.6%/year (95% CI 3.4 to 3.8%) from 399/1000 child-years to 608/1000 child-years, driven by increases in blood tests (8.0%/year, 95% CI 7.7 to 8.4), females aged 11-15 (4.0%/year, 95% CI 3.7 to 4.3), and children from the most socioeconomically deprived group (4.4% /year, 95% CI 4.1 to 4.8). Tests subject to the greatest temporal increases were faecal calprotectin, fractional exhaled nitric oxide and vitamin D. Tests classified as high-use and high-practice variability were iron studies, coeliac testing, vitamin B12, folate, and vitamin D. In this first nationwide study of paediatric test use in primary care, we observed significant temporal increases and practice variability in testing. This reflects inconsistency in practice and diagnosis rates and a scarcity of evidence-based guidance. Increased test use generates more clinical activity with significant resource implications but conversely may improve clinical outcomes. Future research should evaluate whether increased test use and variability are warranted by exploring test indications and test results and directly examine how increased test use impacts on quality of care.
Higher doses of opioids, mental health comorbidities, co-prescription of sedatives, lower socioeconomic status and a history of opioid overdose have been reported as risk factors for opioid overdose; however, the magnitude of these associations and their credibility are unclear. We sought to identify predictors of fatal and nonfatal overdose from prescription opioids. We systematically searched MEDLINE, Embase, CINAHL, PsycINFO and Web of Science up to Oct. 30, 2022, for observational studies that explored predictors of opioid overdose after their prescription for chronic pain. We performed random-effects meta-analyses for all predictors reported by 2 or more studies using odds ratios (ORs) and 95% confidence intervals (CIs). Twenty-eight studies (23 963 716 patients) reported the association of 103 predictors with fatal or nonfatal opioid overdose. Moderate- to high-certainty evidence supported large relative associations with history of overdose (OR 5.85, 95% CI 3.78-9.04), higher opioid dose (OR 2.57, 95% CI 2.08-3.18 per 90-mg increment), 3 or more prescribers (OR 4.68, 95% CI 3.57-6.12), 4 or more dispensing pharmacies (OR 4.92, 95% CI 4.35-5.57), prescription of fentanyl (OR 2.80, 95% CI 2.30-3.41), current substance use disorder (OR 2.62, 95% CI 2.09-3.27), any mental health diagnosis (OR 2.12, 95% CI 1.73-2.61), depression (OR 2.22, 95% CI 1.57-3.14), bipolar disorder (OR 2.07, 95% CI 1.77-2.41) or pancreatitis (OR 2.00, 95% CI 1.52-2.64), with absolute risks among patients with the predictor ranging from 2-6 per 1000 for fatal overdose and 4-12 per 1000 for nonfatal overdose. We identified 10 predictors that were strongly associated with opioid overdose. Awareness of these predictors may facilitate shared decision-making regarding prescribing opioids for chronic pain and inform harm-reduction strategies SYSTEMATIC REVIEW REGISTRATION: Open Science Framework (https://osf.io/vznxj/).
First Nations children in Canada experience health inequities. We aimed to determine whether a self-report health app identified children's needs for support earlier in their illness than would typically occur. Children (aged 8 to 18 yr) were recruited from a rural First Nation community. Children completed the Aaniish Naa Gegii: the Children's Health and Well-being Measure (ACHWM) and then met with a local mental health worker who determined their risk status. ACHWM Emotional Quadrant Scores (EQS) were compared between 3 groups of children: healthy peers (HP) who were not at risk, those with newly identified needs (NIN) who were at risk and not previously identified, and a typical treatment (TT) group who were at risk and already receiving support. We included 227 children (57.1% girls), and the mean age was 12.9 (standard deviation [SD] 2.9) years. The 134 children in the HP group had a mean EQS of 80.1 (SD 11.25), the 35 children in the NIN group had a mean EQS of 67.2 (SD 13.27) and the 58 children in the TT group had a mean EQS of 66.2 (SD 16.30). The HP group had significantly better EQS than the NIN and TT groups (p < 0.001). The EQS did not differ between the NIN and TT groups (p = 0.8). The ACHWM screening process identified needs for support among 35 children, and the associated triage process connected them to local services; the similarity of EQS in the NIN and TT groups highlights the value of community screening to optimize access to services. Future research will examine the impact of this process over the subsequent year in these groups.
New family medicine graduates are a promising group to recruit to underserved rural areas. This study aimed to understand the experiences of this group as they transitioned to practice in rural Ontario. We used a hermeneutic phenomenology approach. Purposive sampling was used to recruit participants who graduated from a Canadian family medicine residency program and worked in a rural community in Ontario (Rurality Index for Ontario score ≥ 40) for at least 1 year within the past 5 years. Participants completed an online demographic survey followed by a virtual semistructured interview (May-August 2022). Interviews were video recorded and transcribed. Two researchers reviewed transcripts for codes, and then codes were reviewed in an iterative process to create themes. Transcripts, codes and themes were reviewed by an independent researcher, and final themes were shared with participants to ensure reliability. We included 18 family physicians in the study. We identified 8 themes and 18 subthemes. The themes identified as important to the experience of new graduates were as follows: choosing rural practice, preparedness for practice, navigating work-life balance, navigating transition to practice, challenges during transition to practice, successes during transition to practice, locuming and emergency medicine as part of rural generalist practice. Most physicians interviewed felt prepared for rural practice and enjoyed their work; however, they faced unique challenges associated with being an early-career physician in rural practice. This study identifies opportunities for improvements, which can guide medical educators, rural communities and their recruiters, new graduates and policy-makers.
Identifying people with Lynch syndrome, a genetic condition predisposing those affected to colorectal, endometrial and other cancers, allows for implementation of risk-reducing strategies for patients and their families. The goal of this study was to describe screening and testing practices for this condition among people with endometrial cancer in Nova Scotia, Canada, and to determine the prevalence of Lynch syndrome in this population. All patients diagnosed with endometrial cancer in Nova Scotia between May 1, 2017, and Apr. 30, 2020 were identified through a provincial gynecologic oncology database. Patients from out of province were excluded. We collected age, body mass index, tumour mismatch repair protein immunohistochemistry results, personal and family histories, and germline testing information for all patients. We identified 465 people diagosed with endometrial cancer during the study period. Most were aged 51 years or older, and had obesity and low-grade early-stage endometrioid tumours. Tumour immunohistochemistry testing was performed in 444 cases (95.5%). Based on local criteria, 189 patients were eligible for genetic counselling, of whom 156 (82.5%) were referred to medical genetics. Of the 98 patients who underwent germline testing, 9 (9.2%) were diagnosed with Lynch syndrome. The prevalence of Lynch syndrome was at least 1.9% (9/465) in this population. Our results illustrate successful implementation of universal tumour testing; however, there remains a gap in access to genetic counselling.
Medical invalidation is a well-documented phenomenon in the literature on chronic illnesses, yet there is a paucity of research capturing the perspectives of young adults living with chronic illnesses, and especially of those who are gender diverse or from groups that face broader societal marginalization. Our study sought to answer the following question: How do young women and nonbinary adults living with chronic illnesses characterize their experiences of medical invalidation and its impact on their health and well-being? This was a patient-oriented qualitative study informed by feminist disability theory. Eligibility requirements included self-identifying as having a chronic illness, self-identifying as a woman or nonbinary person receiving health care in Manitoba, and being between the ages of 18 and 35 years. Participants took part in online arts-based workshops and subsequent focus group discussion in November 2021. Eight women and 2 nonbinary individuals participated. Medical invalidation was experienced by all of the participants at different points in their illness journeys and took a variety of forms depending on their social location and their particular illness, positioning invalidation as an issue of in/visibility. We identified several consequences of medical invalidation, including internalizing invalidation, overcompensating for their illness, avoiding care and, ultimately, symptom intensification. We also present participants' recommendations to avoid medical invalidation. This study provides insight into the phenomenon of medical invalidation, understood as the act of dismissing, minimizing or otherwise not taking patient concerns seriously. We suggest person-centred care may not be enough, and critical reflexivity may help avoid unintentionally invalidating patient experiences.
Patient death is an inevitability during medical training, with subsequent psychologic distress, decreased empathy and worse learning outcomes. We aimed to explore resident experiences with patient death early in training, including the immediate and delayed impacts of these experiences, preparedness of trainees for these events and coping strategies used, potentially identifying gaps and opportunities to further support trainees during difficult or traumatic events. We performed a qualitative study using phenomenology methodology to understand trainees' personal experiences with patient death. Resident physicians who had completed an internal medicine rotation at McMaster University, Hamilton, Ontario, were invited to participate from December 2020 to April 2021. Semistructured interviews were conducted to understand circumstances, emotional responses, support, coping mechanisms and preparedness regarding the patient death experience. Interviews were transcribed and coded to identify emerging themes with the use of thematic and interpretive analysis. Eighteen participants were interviewed. On average, the interviews were 40 minutes in length. The participants' mean age was 27 years. The majority of trainees (10 [56%]) were in their first year of residency, with 5 (28%) from family medicine and 4 (22%) from internal medicine. Most participants (13 [72%]) had experienced their first patient death during medical school. Three themes were identified: patient death circumstances, immediate and delayed emotional impact, and preparedness and coping mechanisms. Unexpected death, pronouncing death, cardiopulmonary resuscitation and communicating with families were common challenges. Feelings of guilt, helplessness and grief followed the events. Feeling underprepared contributed to emotional consequences, including difficulties sleeping, intrusive thoughts and emotional distancing; however, these experiences were consistently normalized by participants. Patient death during medical training can be traumatic for trainees and may perpetuate loss of empathy, changes to practice and residual emotional effects. Educational initiatives to prepare trainees for patient death and teach adaptive coping strategies may help mitigate psychologic trauma and loss of empathy; further research is required to explore these strategies.
In 2018, hospitals were mandated to record homelessness using International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Canada (ICD-10-CA code Z59.0). We sought to answer whether the coding mandate affected the volume of patients identified as experiencing homelessness in acute inpatient hospitalizations and if there was any geographic variation. We conducted a serial cross-sectional study describing 6 fiscal years (2015/16 to 2020/21) of hospital administrative data from the Hospital Morbidity Database. We reported frequencies and percentages of hospitalizations with a Z59.0 diagnostic code and disaggregated by several types of Canadian geographies. Controlling for fiscal quarter (coded Q1 to Q4) and province or territory, adjusted logistic regression models quantified the odds of Z59.0 being coded during hospital stays. The frequency and percentage of people experiencing homelessness in hospitalization records across Canada increased from 6934 (0.12%) in 2015/16 to 21 529 (0.41%) in 2020/21. Trends varied by province and territory. Recording of the Z59.0 code increased following the mandate (adjusted odds ratio 2.29, 95% confidence interval 2.25-2.32), relative to the pre-mandate period. The 2018 coding mandate coincided with an increase in the use of the Z59.0 code to document homelessness in health care administrative data; however, trends varied by jurisdiction. The ICD-10-CA code Z59.0 presents a promising opportunity for standardized and routinely collected data to identify people experiencing homelessness in hospital administrative data.
Medical assistance in dying (MAiD) was legalized in Canada in 2016, with legislation updated in 2021. It is unclear whether resources are available to help patients make this difficult decision; therefore, we sought to identify and quality appraise Canadian MAiD resources for supporting patients making this decision. We conducted an environmental scan by searching Canadian websites for online MAiD resources that were published after the 2016 MAiD legislation, patient targeted, publicly accessible and able to inform decisions about MAiD in Canada. We excluded resources that targeted health care professionals or policy-makers, service protocols and personal narratives. Two authors appraised resources using the International Patient Decision Aids Standards (IPDAS) criteria and the Patient Education Materials Assessment Tool (PEMAT) for health literacy. Descriptive analysis was conducted. We defined resources as patient decision aids if 7 IPDAS defining criteria were met, and we rated resources as adequate for understandability or actionability if the PEMAT score was 70% or greater. We identified 80 MAiD resources. As of March 2023, 62 resources (90%) provided eligibility according to the 2021 legislation and 11 did not discuss any eligibility criteria. The median IPDAS score was 3 out of 7; 52% discussed alternative options and none provided benefits or harms. Of 80 resources, 59% were adequate for understandability and 29% were adequate for actionability. Although many resources on MAiD were updated with 2021 legislation, few were adequate to support patients with lower health literacy. There is a need to determine whether a patient decision aid would be appropriate for people in Canada considering MAiD.
