Background: Most children who need emergency care visit general emergency departments and urgent care centres; the weighted pediatric readiness score (WPRS) is currently used to evaluate emergency departments' readiness for pediatric patients. The aim of this study was to determine whether a higher WPRS was associated with decreased mortality and improved health care outcomes and utilization.

Methods: We conducted a systematic review of cohort and cross-sectional studies on emergency departments that care for children (age ≤ 21 yr). We searched MEDLINE (Ovid), Embase (Ovid), the Cochrane Library (Wiley), CINAHL (EBSCO), Global Health (Ovid) and Scopus from inception until July 29, 2022. Articles identified were screened for inclusion by 2 independent reviewers. The primary outcome was mortality, and the secondary outcomes were health care outcomes and utilization. We used the Newcastle-Ottawa Scale to assess for quality and bias of the included studies. The I ² statistic was calculated to quantify study heterogeneity.

Results: We identified 1789 articles. Eight articles were included in the final analysis. Three studies showed an inverse association between highest WPRS quartile and pediatric mortality (pooled odds ratio [OR] 0.45, 95% confidence interval [CI] 0.26 to 0.78; I ² = 89%, low certainty of evidence) in random-effects meta-analysis. Likewise, 1 study not included in the meta-analysis also reported an inverse association with a 1-point increase in WPRS (OR 0.93, 95% CI 0.88 to 0.98). One study reported that the highest WPRS quartile was associated with shorter length of stay in hospital (β -0.36 days, 95% CI -0.61 to -0.10). Three studies concluded that the highest WPRS quartile was associated with fewer interfacility transfers. The certainty of evidence is low for mortality and moderate for the studied health care outcomes and utilization.

Interpretation: The data suggest a potential inverse association between the WPRS of emergency departments and mortality risk in children. More studies are needed to refute or confirm these findings.

Background: 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.

Methods: 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.

Results: 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.

Interpretation: 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.

Background: 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?

Methods: 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.

Results: 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.

Interpretation: 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.

Background: First Nations people in Canada are overrepresented among those who have undergone nontraumatic lower extremity amputation, and are more likely to be younger, have diabetic foot infections and have no previous revascularization procedures than non-First Nations populations who have undergone lower extremity amputations. We sought to identify access barriers for high-risk First Nations patients, explore patients' experiences with health care systems and identify solutions.

Methods: Employing a community participatory research design, we engaged representatives from 2 communities. They assisted with research design and data analysis, and approved the final manuscript. Using a hermeneutic phenomenological approach and purposeful sampling, we conducted 5 semistructured focus groups between August and December 2021 with community health care teams and patients at risk for, or who had previously undergone, a nontraumatic lower extremity amputation.

Results: Patients' (n = 10) and community health care providers' (n = 18) perspectives indicated that barriers to health care access led to delayed care and increased complications and risk for lower extremity amputations, leading to aggressive procedures upon receiving care. Barriers to care led to negative experiences at urban centres and aggressive procedures created further distrust, leading to care disengagement and poor outcomes. Patients and providers both suggested building stronger partnerships between urban and rural health care providers, improving education for patients and health care providers and identifying innovative strategies to improve patients' overall health.

Interpretation: Systemic changes, health promotional program and reliable on-reserve primary care are needed to create equitable access for First Nation patients at risk for lower extremity amputations. The study results imply that health care delivery for First Nations patients at risk for lower extremity amputations can be improved through stronger partnership and communication between urban and community providers, and continued education and cultural competency training for urban health care providers.

Background: Sugar-sweetened beverage taxation has been proposed as a public health policy to reduce consumption, and compared with other ethnic or racialized groups in Canada, off-reserve Indigenous populations consume sugar-sweetened beverages at higher frequencies and quantities. We sought to explore the acceptability and anticipated outcomes of a tax on sugar-sweetened beverages among Indigenous adults residing in an inner-city Canadian neighbourhood.

Methods: Using a community-based participatory research approach, we conducted semistructured interviews (November 2019-August 2020) with urban Indigenous adults using purposive sampling. Interviews were audio-recorded, transcribed verbatim and analyzed using theoretical thematic analysis.

Results: All 20 participants (10 female, 8 male and 2 two-spirit) consumed sugar-sweetened beverages on a regular, daily basis at the time of the interview or at some point in their lives. Most participants were opposed to and concerned about the prospect of sugar-sweetened beverage taxation owing to 3 interconnected themes: government is not trustworthy, taxes are ineffective and lead to inequitable outcomes, and Indigenous self-determination is critical. Participants discussed government's mismanagement of previous taxes and lack of prioritization of their community's specific needs. Most participants anticipated that Indigenous people in their community would continue to consume sugar-sweetened beverages, but that a tax would result in fewer resources for other necessities, including foods deemed healthy.

Interpretation: Low support for the tax among urban Indigenous people is characterized by distrust regarding the tax, policy-makers and its perceived effectiveness. Findings underscore the importance of self-determination in informing health policies that are equitable and nonstigmatizing.

Background: People with HIV infection are at higher risk for certain cancers than the general population. We compared trends in infection-related and infection-unrelated cancers among people with and without HIV infection.

Methods: We conducted a retrospective population-based matched cohort study of adults with and without HIV infection using linked health administrative databases in Ontario, Canada. Participants were matched on birth year, sex, census division (rurality), neighbourhood income quintile and region of birth. We followed participants from cohort entry until the earliest of date of cancer diagnosis, date of death, Nov. 1, 2020, or date of loss to follow-up. Incident cancers identified from Jan. 1, 1996, to Nov. 1, 2020, were categorized as infection-related or-unrelated. We examined calendar periods 1996-2003, 2004-2011 and 2012-2020, corresponding to the early combination antiretroviral therapy (cART), established cART and contemporary cART eras, respectively. We used competing risk analyses to examine trends in cumulative incidence by calendar period, age and sex, and cause-specific hazard ratios (HRs).

Results: We matched 20 304 people with HIV infection to 20 304 people without HIV infection. A total of 2437 cancers were diagnosed, 1534 (62.9%) among infected people and 903 (37.0%) among uninfected people. The risk of infection-related cancer by age 65 years for people with HIV infection decreased from 19.0% (95% confidence interval [CI] 15.6%-22.3%) in 1996-2011 to 10.0% (95% CI 7.9%-12.1%) in 2012-2020. Compared to uninfected people, those with HIV infection had similar HRs of infection-unrelated cancer but increased rates of infection-related cancer, particularly among younger age groups (25.1 [95% CI 13.2-47.4] v. 1.9 [95% CI 1.0-3.7] for age 18-39 yr v. ≥ 70 yr); these trends were consistent when examined by sex.Interpretation: We observed significantly higher rates of infection-related, but not infection-unrelated, cancer among people with HIV infection than among uninfected people. The elevated rate of infection-related cancer in 2012-2020 highlights the importance of early and sustained antiretroviral therapy along with cancer screening and prevention measures.

Background: 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.

Methods: 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.

Results: 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.

Interpretation: 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.

Background: Métis are a culturally unique and distinct population, yet little research has evaluated their health separate from the broader Indigenous population. We sought to explore current literature regarding the health of Métis Peoples in Canada and identify potential trends and gaps.

Methods: Using the Arksey-O'Malley, 5-stage, scoping review method, we searched PubMed, MEDLINE, iPortal Indigenous Articles Portal Research Tool and pertinent reference lists using the terms "Métis," "health" and "Canada." Two reviewers conducted the initial searches independently, including English articles from 2012 to 2022, and focused on only Métis populations' health within Canada. We described characteristics of the articles and themes for discussion.

Results: Of the 572 articles we identified, we included a total of 28 articles in this scoping review, of which 16 were quantitative, 9 were qualitative and 3 used mixed methods. Thirteen articles used consultation with Métis communities as part of their methods, and 8 extracted data from national surveys. One article focused on children, while all other articles focused on adults. Nine articles used data from across Canada, 6 were based in Ontario, 5 in Alberta and 4 each in British Columbia and Manitoba. Themes included health, well-being and spirituality; mental health and substance use; health conditions and risk factors; access to adequate health resources; and experiences in health care.

Interpretation: Métis-specific health research is lacking in Canada, with a gap in volume, subject matter and diversity in the demographics studied. This review illustrates the need for more research with strong community engagement to further explore Métis health and health service needs.

Background: Although clinical empathy - the ability of a physician to understand a patient's illness experience, communicate this understanding and act collaboratively to create a treatment plan - provides substantial benefits to both physicians and patients, medical students typically experience a decline in empathy during training. The primary objective of this study was to generate a model of clinical empathy grounded in the perspectives of people with chronic illness living in Canada, to promote empathy-focused curricular development in Canadian medical education.

Methods: We conducted a qualitative focus group study using a constructivist grounded theory approach. We recruited adults (age ≥ 18 yr) with chronic illness who had recently seen a physician in Canada from virtual support groups. Six semistructured virtual focus groups with 3-5 participants each were scheduled between June and September 2021. We coded the transcripts using the constant comparative method, allowing for the construction of an overarching theory.

Results: Twenty patients (17 women and 3 men) participated in the focus groups; 1 group had 2 participants because 1 participant failed to appear. The majority of participants (14 [70%]) had at least a college degree. The mean rating for overall satisfaction with the Canadian health care system was 5.4/10.0 (median 5.0). The emergent theory showed that the perceived presence of physician empathy engendered positive internal processing by patients, leading to increased health care efficacy and enhanced mental health outcomes. Negative patient processing in response to the perceived absence of empathy led to reduced quality of health care delivery (e.g., ineffective referrals and more appointments), increased use of health care resources, disruptions in patients' personal lives, and negative physical and mental health outcomes.

Interpretation: Clinical empathy can have life-altering impacts on patients, and its absence may increase resource use. As empathy involves understanding patients' lived experiences, any valid intervention to improve clinical empathy must be informed by patient perspectives.

Background: Challenges in timely access to one's usual primary care physician and the ongoing use of walk-in clinics have been major health policy issues in Ontario for over a decade. We sought to determine the association between patient-reported timely access to their usual primary care physician or clinic and their use of walk-in clinics.

Methods: We conducted a cross-sectional study of Ontario residents who had a primary care physician by linking population-based administrative data to Ontario's Health Care Experience Survey, collected between 2013 and 2020. We described sociodemographic characteristics and health care use for users of walk-in clinics and nonusers. We measured the adjusted association between self-reported same-day or next-day access and after-hours access to usual primary care physicians or clinics and the use of walk-in clinics in the previous 12 months.

Results: Of the 60 935 total responses from people who had a primary care physician, 16 166 (weighted 28.6%, unweighted 26.5%) reported visiting a walk-in clinic in the previous 12 months. Compared with nonusers, those who used walk-in clinics were predominantly younger, lived in large and medium-sized urban areas and reported a tight, very tight or poor financial situation. Respondents who reported poor same-day or next-day access to their primary care physician or clinic were more likely to report having attended a walk-in clinic in the previous 12 months than those with better access (adjusted odds ratio [OR] 1.23, 95% confidence interval [Cl] 1.13-1.34). Those who reported being unaware that their primary care physician offered after-hours care had a higher likelihood of going to a walk-in clinic (adjusted OR 1.14, 95% Cl 1.07-1.21).

Interpretation: In this population-based health survey, patient-reported use of walk-in clinics was associated with a reported lack of access to same-day or next-day care and unawareness of after-hours care by respondents' usual primary care physicians. These findings could inform policies to improve access to primary care, while preserving care continuity.
