RESUMO
Introduction: Patients with major mental illness (MMI) and substance use disorders (SUD) face barriers in accessing healthcare. In this population-based retrospective cohort study, we investigated the uptake of COVID-19 vaccination in Ontario, Canada among community-dwelling individuals receiving healthcare for major mental illness (MMI) and/or substance use disorders (SUD), comparing them to matched general population controls. Methods: Using linked health administrative data, we identified 337,290 individuals receiving healthcare for MMI and/or SUD as of 14 December 2020, matched by age, sex, and residential geography to controls without such healthcare. Follow-up extended until 31 December 2022 to document vaccination events. Results: Overall, individuals receiving healthcare for MMI and/or SUD (N = 337,290) had a slightly lower uptake of first (cumulative incidence 82.45% vs. 86.44%; hazard ratio [HR] 0.83 [95% CI 0.82-0.83]) and second dose (78.82% vs. 84.93%; HR 0.77 [95% CI 0.77-0.78]) compared to matched controls. Individuals receiving healthcare for MMI only (n = 146,399) had a similar uptake of first (87.96% vs. 87.59%; HR 0.97 [95% CI 0.96-0.98]) and second dose (86.09% vs. 86.05%, HR 0.94 [95% CI 0.93-0.95]). By contrast, individuals receiving healthcare for SUD only (n = 156,785) or MMI and SUD (n = 34,106) had significantly lower uptake of the first (SUD 78.14% vs. 85.74%; HR 0.73 [95% CI 0.72-0.73]; MMI & SUD 78.43% vs. 84.74%; HR 0.76 [95% CI 0.75-0.77]) and second doses (SUD 73.12% vs. 84.17%; HR 0.66 [95% CI 0.65-0.66]; MMI & SUD 73.48% vs. 82.93%; HR 0.68 [95% CI 0.67-0.69]). Discussion: These findings suggest that effective strategies to increase vaccination uptake for future COVID-19 and other emerging infectious diseases among community-dwelling people with SUD are needed.

OBJECTIVES: Conducting longitudinal health research about people experiencing homelessness poses unique challenges. Identification through administrative data permits large, cost-effective studies; however, case validity in Ontario is unknown after a 2018 Canada-wide policy change mandating homelessness coding in hospital databases. We validated case definitions for identifying homelessness using Ontario health administrative databases after introduction of this coding mandate. STUDY DESIGN AND SETTING: We assessed 42 case definitions in a representative sample of people experiencing homelessness in Toronto (n = 640) from whom longitudinal housing history (ranging from 2018 to 2022) was obtained, and a randomly selected sample of presumably housed people (n = 128,000) in Toronto. We evaluated sensitivity, specificity, positive and negative predictive values, and positive likelihood ratios to select an optimal definition, and compared the resulting true positives against false positives and false negatives to identify potential causes of misclassification. RESULTS: The optimal case definition included any homelessness indicator during a hospital-based encounter within 180 days of a period of homelessness (sensitivity = 52.9%; specificity = 99.5%). For periods of homelessness with ≥1 hospital-based healthcare encounter, the optimal case definition had greatly improved sensitivity (75.1%) while retaining excellent specificity (98.5%). Review of false positives suggested that homeless status is sometimes erroneously carried forward in healthcare databases after an individual transitioned out of homelessness. CONCLUSION: Case definitions to identify homelessness using Ontario health administrative data exhibit moderate to good sensitivity and excellent specificity. Sensitivity has more than doubled since the implementation of a national coding mandate. Mandatory collection and reporting of homelessness information within administrative data present invaluable opportunities for advancing research on the health and healthcare needs of people experiencing homelessness.
RESUMO
AIMS: To compare processes of diabetes care by homeless status. METHODS: A population-based propensity matched cohort study was conducted in Ontario, Canada. People with diabetes were identified in administrative healthcare data between April 2006 and March 2019. Those with a documented history of homelessness were matched to non-homeless controls. Data on processes of care measures included glucose monitoring tests, screening for microvascular complications, and physician follow-up. Differences in processes of care were compared by homeless status using proportions, risk ratios, and rate ratios. RESULTS: Of the 1,076,437 people with diabetes, 5219 matched pairs were identified. Homelessness was associated with fewer tests for glycated hemoglobin (RR = 0.63; 95 %CI: 0.60-0.67), LDL cholesterol (RR = 0.80; 95 %CI: 0.78-0.82), serum creatinine (RR = 0.94; 95 %CI: 0.92-0.97), urine protein quantification (RR = 0.62; 95 %CI: 0.59-0.66), and eye examinations (RR = 0.74; 95 %CI: 0.71-0.77). People with a history of homelessness were less likely to use primary care for diabetes management (RR = 0.62; 95 %CI: 0.59-0.66) or specialist care (RR = 0.87; 95 %CI: 0.83-0.91) compared to non-homeless controls. CONCLUSIONS: Disparities in diabetes care are evident for people with a history of homelessness and contribute to excess morbidity in this population. These data provide an impetus for investment in tailored interventions to improve healthcare equity and prevent long-term complications.

Social capital is a collective asset important for individual and population well-being. Individuals who experience homelessness may face barriers in accessing social capital due to health challenges, small social networks, and social exclusion. Data from a 4-year longitudinal study was used to determine if housing stability predicted greater social capital and if this relationship was mediated by social support and psychological integration for a sample of 855 homeless and vulnerably housed participants living in three Canadian cities. Findings showed that housing stability was not associated with trust and linking social capital. However, higher levels of social support and psychological integration had a mediating effect on the association between housing stability and trust and linking social capital. These findings highlight the importance of social support and psychological integration as means of promoting social capital for people who experience homelessness and vulnerable housing. Social interventions for housed individuals with histories of homelessness may be an avenue to foster greater social capital by building relationships with neighbors and connections to community resources and activities.
RESUMO
PURPOSE: Recent anecdotal reports suggest increasing numbers of people experiencing homelessness are visiting emergency departments (EDs) during cold weather seasons due to inadequate shelter availability. We examined monthly ED visits among patients experiencing homelessness to determine whether there has been a significant increase in such visits in 2022/2023 compared to prior years. METHODS: We used linked health administrative data to identify cohorts experiencing homelessness in Ontario between October and March of the 2018/2019 to 2022/2023 years. We analyzed the monthly rate of non-urgent ED visits as a proxy measure of visits plausibly attributable to avoidance of cold exposure, examining rates among patients experiencing homelessness compared to housed patients. We excluded visits for overdose or COVID-19. We assessed level and significance of change in the 2022/2023 year as compared to previous cold weather seasons using Poisson regression. RESULTS: We identified a total of 21,588 non-urgent ED visits across the observation period among patients experiencing homelessness in Ontario. Non-urgent ED visits increased 27% (RR 1.24 [95% CI 1.14-1.34]) in 2022/2023 compared to previous cold weather seasons. In Toronto, such visits increased by 70% (RR 1.68 [95% CI 1.57-1.80]). Among housed patients, non-urgent ED visits did not change significantly during this time period. CONCLUSION: Rates of ED visits plausibly attributable to avoidance of cold exposure by individuals experiencing homelessness increased significantly in Ontario in 2022/2023, most notably in Toronto. This increase in ED visits may be related to inadequate access to emergency shelter beds and warming services in the community.
RéSUMé: OBJECTIFS: Des rapports anecdotiques récents suggèrent qu'un nombre croissant de personnes en situation d'itinérance visitent les services d'urgence (SU) pendant les saisons froides en raison de la disponibilité insuffisante d'hébergement d'urgence. Nous avons examiné les visites mensuelles aux urgences chez les personnes en situation d'itinérance afin de déterminer s'il y a eu une augmentation significative de ces visites en 2022-2023 par rapport aux années précédentes. MéTHODES: Nous avons utilisé des données administratives de santé liées pour identifier les cohortes de personnes en situation d'itinérance en Ontario entre octobre et mars des années 2018/2019 à 2022/2023. Nous avons analysé le taux mensuel de visites aux urgences non urgentes comme mesure approximative des visites vraisemblablement attribuables à l'évitement de l'exposition au froid, en examinant les taux chez les personnes en situation d'itinérance par rapport aux patients logés. Nous avons exclu les visites pour surdose ou COVID-19. Nous avons évalué le niveau et l'importance du changement dans l'année 2022/2023 par rapport aux saisons froides précédentes en utilisant la régression de Poisson. RéSULTATS: Nous avons recensé un total de 21 588 visites non urgentes aux urgences au cours de la période d'observation chez des personnes en situation d'itinérance en Ontario. Les visites aux urgences non urgentes ont augmenté de 27 % (RR 1,24 [IC à 95 % 1,14-1,34]) en 20222023 par rapport aux saisons froides précédentes. À Toronto, ces visites ont augmenté de 70 % (RR 1,68 [IC à 95 % 1,57-1,80]). Parmi les patients logés, les visites aux urgences non urgentes n'ont pas changé de façon significative pendant cette période. CONCLUSIONS: Les taux de visites aux urgences attribuables vraisemblablement à l'évitement de l'exposition au froid par les personnes en situation d'itinérance ont augmenté considérablement en Ontario en 20222023, surtout à Toronto. Cette augmentation du nombre de visites aux urgences peut être liée à un accès inadéquat aux lits des refuges d'urgence et aux services de réchauffement dans la collectivité.

Service restrictions refer to temporary or permanent bans of individuals from a program or an organization's services, and are widely used in emergency shelter systems. Limited research exists on how service restrictions unfold and their impacts on people experiencing homelessness. This qualitative study used in-depth interviews with timeline mapping to examine the antecedents and consequences of service restrictions from emergency shelters among people experiencing homelessness in two cities in Ontario, Canada. A total of 49 people experiencing homelessness who had been restricted from an emergency shelter program in the past year were recruited and included in the study analysis. A pragmatic and integrative approach was used for data analysis that involved the development of meta-matrices to identify prominent and divergent perspectives and experiences with regard to service restriction antecedents and consequences. Study findings underscored that service restrictions were often the result of violence and aggression, primarily between service users. There were regional differences in other service restriction reasons, including substance use and possession. Service restrictions affected the shelter status of almost all participants, with many subsequently experiencing unsheltered homelessness, and cycling through institutional health, social, and criminal justice services (i.e., institutional circuitry). Other health and social consequences included substance use relapses and hospitalizations; cold-related injuries due to post-restriction unsheltered homelessness; suicidality; food insecurity; diminished contact with support network and connections; and intense feelings of anger, fear, and hopelessness. Overall, the study findings advance our understanding of the role of homeless services in pathways into unsheltered homelessness and institutional circuitry, which raise critical questions about how to mitigate the harms associated with service restrictions, while concurrently facilitating safety and upholding the rights of people experiencing homelessness and emergency shelter staff.

BACKGROUND: Accurate estimation of SARS-CoV-2 re-infection is crucial to understanding the connection between infection burden and adverse outcomes. However, relying solely on PCR testing results in underreporting. We present a novel approach that includes longitudinal serologic data, and compared it against testing alone among people experiencing homelessness. METHODS: We recruited 736 individuals experiencing homelessness in Toronto, Canada, between June and September 2021. Participants completed surveys and provided saliva and blood serology samples every three months over 12 months of follow-up. Re-infections were defined as: positive PCR or rapid antigen test (RAT) results > 90 days after initial infection; new serologic evidence of infection among individuals with previous infection who sero-reverted; or increases in anti-nucleocapsid in seropositive individuals whose levels had begun to decrease. RESULTS: Among 381 participants at risk, we detected 37 re-infections through PCR/RAT and 98 re-infections through longitudinal serology. The comprehensive method identified 37.4 re-infection events per 100 person-years, more than four-fold more than the rate detected through PCR/RAT alone (9.0 events/100 person-years). Almost all test-confirmed re-infections (85%) were also detectable by longitudinal serology. CONCLUSIONS: Longitudinal serology significantly enhances the detection of SARS-CoV-2 re-infections. Our findings underscore the importance and value of combining data sources for effective research and public health surveillance.

AIMS: To measure the change in proportion of opioid-related overdose deaths attributed to people experiencing homelessness and to compare the opioid-related fatalities between individuals experiencing homelessness and not experiencing homelessness at time of death. DESIGN, SETTING AND PARTICIPANTS: Population-based, time-trend analysis using coroner and health administrative databases from Ontario, Canada from 1 July 2017 and 30 June 2021. MEASUREMENTS: Quarterly proportion of opioid-related overdose deaths attributed to people experiencing homelessness. We also obtained socio-demographic and health characteristics of decedents, health-care encounters preceding death, substances directly contributing to death and circumstances surrounding deaths. FINDINGS: A total of 6644 individuals (median age = 40 years, interquartile range = 31-51; 74.1% male) experienced an accidental opioid-related overdose death, among whom 884 (13.3%) were identified as experiencing homelessness at the time of death. The quarterly proportion of opioid-related overdose deaths attributed to people experiencing homelessness increased from 7.2% (26/359) in July-September 2017 to 16.8% (97/578) by April-June 2021 (trend test P < 0.01). Compared with housed decedents, those experiencing homelessness were younger (61.3 versus 53.1% aged 25-44), had higher prevalence of mental health or substance use disorders (77.1 versus 67.1%) and more often visited hospitals (32.1 versus 24.5%) and emergency departments (82.6 versus 68.5%) in the year prior to death. Fentanyl and its analogues more often directly contributed to death among people experiencing homelessness (94.0 versus 81.4%), as did stimulants (67.4 versus 51.6%); in contrast, methadone was less often present (7.8 versus 12.4%). Individuals experiencing homelessness were more often in the presence of a bystander during the acute toxicity event that led to death (55.8 versus 49.7%); and where another individual was present, more often had a resuscitation attempted (61.7 versus 55.1%) or naloxone administered (41.2 versus 28.9%). CONCLUSIONS: People experiencing homelessness account for an increasing proportion of fatal opioid-related overdoses in Ontario, Canada, reaching nearly one in six such deaths in 2021.

PURPOSE: In patients with adolescent idiopathic scoliosis (AIS) undergoing anterior vertebral tethering (AVBT), some will subsequently require posterior spinal fusion (PSF). Limited data exist on clinical and radiographic outcomes of fusion after tether failure. METHODS: 490 patients who underwent AVBT were retrospectively analyzed. Twenty patients (4.1%) subsequently underwent conversion to PSF. A control group of patients with primary PSF (no previous AVBT) was matched for comparison. Data were compared using paired t-tests and Fisher Exact Tests. RESULTS: There was a significant increase in estimated blood loss (EBL) (p = 0.002), percent estimated blood volume (%EBV) (p = 0.013), operative time (p = 0.002), and increased amount of fluoroscopy (mGy) (p = 0.04) as well as number of levels fused (p = 0.02) in the AVBT conversion group compared to primary fusion. However, no difference was found in implant density (p = 0.37), blood transfusions (p = 0.11), or intraoperative neuromonitoring events (p > 0.99). Both groups attained similar thoracic and lumbar percent correction (major coronal curve angle) from pre-op to the latest follow-up (thoracic p = 0.507, lumbar p = 0.952). CONCLUSION: A subset of patients with AVBT will require conversion to PSF. Although technically more challenging, revision surgery can be safely performed with similar clinical and radiographic outcomes to primary PSF.

Purpose: To characterize the availability of social determinants of health data in the electronic health record of pediatric ophthalmology patients and to examine the association of social determinants of health with attendance at scheduled operating room and clinic visits. Methods: This was a retrospective cohort study of pediatric ophthalmology patients seen at The Hospital for Sick Children between June 1, 2018, and May 23, 2022. Data were collected on demographics, diagnosis, and management-plan. The χ2 tests and multivariable regression were used to examine associations between social determinants of health and attendance at scheduled operating room and clinic visits. Results: The cohort consisted of 26,102 study subjects with 31,288 unique eye-related diagnoses representing 57 unique ICD-10 codes. Availability of data in the electronic health record ranged from 100% for sex, age and postal code to 0.1% for ethnic group. Female sex (P = 0.004) and urbanicity (P = 0.05) were associated with higher operating room visit cancellations. Female sex (P = 0.002), age group 0-13 (P ≤ 0.001), low-medium neighborhood income quintile (P ≤ 0.001), residence of Northern Ontario (P ≤ 0.001), and urbanicity (P ≤ 0.001) were associated with higher clinic visit cancellations and no-shows. Conclusions: At a major tertiary-care hospital in Canada, key social determinant data such as ethnicity are not consistently available in the electronic health record of pediatric ophthalmology patients. Female sex, younger age, and living in a rural area or neighborhood with low-medium income quintile may be predictors of missed visits and require further study. Translational Relevance: This study highlights a need for improved documentation of social determinants of health variables in electronic health records.

Before the COVID-19 pandemic, patients in Ontario who were uninsured due to immigration status faced barriers to hospital care that resulted in preventable illness and death. In March 2020, the Ontario Ministry of Health issued a memo indicating that it would pay for medically necessary hospital services for uninsured patients (Ontario Ministry of Health 2020). Front-line providers and research workers associated with the Health Network for Uninsured Clients (HNUC) set out to ensure that hospitals in Toronto implemented the ministry's memo. In this paper, we demonstrate a model of front-line worker-led knowledge translation informed by real-time data and anchored in clearly articulated values and goals. On April 1, 2023, the Ontario Ministry of Health cancelled this uninsured coverage (Ontario Ministry of Health 2023). Healthcare provider associations, grassroots groups and coalitions - including the HNUC - are mobilizing to see this uninsured coverage reinstated.

Homelessness results in barriers to effective diabetes self-management. Programs targeting individuals facing homelessness have refined strategies to address these barriers. We sought to develop a framework to characterize these strategies that could help multidisciplinary providers to better support these individuals. Semi-structured interviews were conducted with a purposive sample of health and social care providers working in diabetes or homelessness in five Canadian cities (n=96). Interview transcripts were analyzed through qualitative thematic analysis. Providers described three groups of approaches that enabled care for this population. Person-centered provider behaviours: This included tailoring care plans to accommodate individuals' situational constraints. Lower-barrier organizational structure: Providers developed specialized organizational processes to increase accessibility. Bridging to larger care systems: Strategies included providing access to support workers. Across diverse program structures, similar approaches are used to enhance diabetes care for individuals who are experiencing homelessness, highlighting tangible opportunities for mainstream services to better engage with this population.

OBJECTIVES: The overarching objective of this mixed methods longitudinal study was to understand whether and how rent subsidies and mentorship influenced socioeconomic inclusion outcomes for youth exiting homelessness. The focus of this paper is on the qualitative objectives, which evolved from a primary focus on exploring how study mentorship was working as a facilitator of socioeconomic inclusion to focusing on how participants navigated the hazy, liminal space between socioeconomic exclusion and inclusion. METHODS: This was a convergent mixed methods study scaffolded by community-based participatory action axiology. The quantitative component is reported elsewhere and involved a 2-year pilot randomized controlled trial where 24 participants received rent subsidies and 13 were randomly assigned a study mentor; proxy indicators of socioeconomic inclusion were measured every 6 months for 2.5 years. Qualitative objectives were explored using a qualitative descriptive design and theoretically framed using critical social theory. The lead author interviewed 12 participants every 6 months for 2.5 years. Qualitative interviews were analyzed using reflexive thematic analysis with an emphasis on critical interpretation. RESULTS: Navigating the liminal space between socioeconomic exclusion and inclusion was complex and non-linear, and the way youth navigated that journey was more strongly associated with factors like informal mentorship (naturally occurring "coach-like" mentorship) and identity capital (sense of purpose, control, self-efficacy, and self-esteem), rather than whether or not they were assigned a formal study mentor. CONCLUSION: A holistic approach integrating coaching and attention to identity capital alongside economic supports may be key to helping youth exiting homelessness achieve socioeconomic inclusion.
RéSUMé: OBJECTIFS: L'objectif primordial de cette étude longitudinale à méthodes mixtes était de comprendre si et comment les suppléments au loyer et le mentorat influencent les résultats sur le plan de l'inclusion socioéconomique pour les jeunes qui sortent du sans-abrisme. Notre article porte sur des objectifs qualitatifs; à l'origine, il visait principalement à explorer l'efficacité du mentorat des études comme moyen de faciliter l'inclusion socioéconomique, puis il a évolué en s'attachant à la manière dont les participantes et les participants trouvaient leurs repères dans l'espace liminaire flou entre l'exclusion et l'inclusion socioéconomique. MéTHODE: Cette étude à méthodes mixtes convergentes est échafaudée sur l'axiologie de l'action participative communautaire. L'élément quantitatif, qui fait l'objet d'un autre article, a impliqué un essai pilote comparatif randomisé de deux ans où 24 participantes et participants ont reçu des suppléments au loyer, et 13 ont été jumelés de façon aléatoire à un tuteur ou une tutrice scolaire; des indicateurs approximatifs de l'inclusion socioéconomique ont été mesurés tous les six mois pendant deux ans et demi. Les objectifs qualitatifs ont été explorés à l'aide d'un protocole descriptif qualitatif et encadrés théoriquement par la théorie sociale critique. L'autrice principale a interviewé 12 participantes et participants tous les six mois pendant deux ans et demi. Les entretiens qualitatifs ont été analysés en employant l'analyse thématique réflexive et en mettant l'accent sur l'interprétation critique. RéSULTATS: L'exploration de l'espace liminaire entre l'exclusion et l'inclusion socioéconomique était complexe et non linéaire, et le parcours des jeunes était davantage associé à des facteurs comme le mentorat informel (le mentorat naturel semblable à celui d'un entraîneur ou d'une entraîneuse) et le capital identitaire (le sentiment d'avoir un but, le contrôle, l'auto-efficacité et l'estime de soi) qu'au fait d'avoir ou non été jumelés à un tuteur ou une tutrice dans leurs études. CONCLUSION: Une démarche holistique intégrant l'encadrement et l'attention au capital identitaire, en plus des mesures de soutien économique, pourrait être essentielle pour aider les jeunes qui sortent du sans-abrisme à s'intégrer sur le plan socioéconomique.

PURPOSE: Homelessness increases the risk of cold-related injuries. We examined emergency department visits for cold-related injuries in Toronto over a 4-year period, comparing visits for patients identified as homeless to visits for patients not identified as homeless. METHODS: This descriptive analysis of visits to emergency departments in Toronto between July 2018 and June 2022 used linked health administrative data. We measured emergency department visits with cold-related injury diagnoses among patients experiencing homelessness and those not identified as homeless. Rates were expressed as a number of visits for cold-related injury per 100,000 visits overall. Rate ratios were used to compare rates between homeless vs. not homeless groups. RESULTS: We identified 333 visits for cold-related injuries among patients experiencing homelessness and 1126 visits among non-homeless patients. In each of the 4 years of observation, rate ratios ranged between 13.6 and 17.6 for cold-related injuries overall, 13.7 and 17.8 for hypothermia, and 10.3 and 18.3 for frostbite. Rates per 100,000 visits in the fourth year (July 2021 to June 2022) were significantly higher than in the pre-pandemic period. Male patients had higher rates, regardless of homelessness status; female patients experiencing homelessness had higher rate ratios than male patients experiencing homelessness. CONCLUSION: Patients experiencing homelessness visiting the emergency department are much more likely to be seen for cold-related injuries than non-homeless patients. Additional efforts are needed to prevent cold-related exposure and consequent injury among people experiencing homelessness.
RéSUMé: OBJECTIF: L'itinérance augmente le risque de blessures liées au froid. Nous avons examiné les visites aux urgences pour des blessures liées au froid à Toronto sur une période de quatre ans, en comparant les visites de patients en situation d'itinérance aux visites de patients pas en situation d'itinérance. MéTHODES: Cette analyse descriptive des visites aux services d'urgence à Toronto entre juillet 2018 et juin 2022 a utilisé des données administratives de santé liées. Nous avons mesuré les visites aux services d'urgence avec un diagnostic de blessure liée au froid parmi les patients en situation d'itinérance et ceux pas en situation d'itinérance. Les taux ont été exprimés en nombre de visites pour les blessures liées au froid par 100 000 visites au total. Le rapport de taux ont été utilisés pour comparer les taux entre les groupes en situation d'itinérance et ceux pas en situation d'itinérance. RéSULTATS: Nous avons identifié 333 visites pour des blessures liées au froid chez les patients en situation d'itinérance et 1126 chez les patients pas en situation d'itinérance. Au cours de chacune des quatre années d'observation, les rapports de taux variaient entre 13,6 et 17,6 pour l'ensemble des blessures liées au froid, 13,7 et 17,8 pour l'hypothermie et 10,3 et 18,3 pour les engelures. Les taux par 100 000 visites au cours de la quatrième année (de juillet 2021 à juin 2022) étaient considérablement plus élevés que pendant la période précédant la pandémie. Les patients de sexe masculin affichaient des taux plus élevés, peu importe leur statut d'itinérance; les patients de sexe féminin en situation d'itinérance affichaient des rapports de taux plus élevés que les patients de sexe masculin en situation d'itinérance. CONCLUSION: Les patients en situation d'itinérance qui se rendent à l'urgence sont beaucoup plus susceptibles d'être vus pour des blessures liées au froid que les autres. Des efforts supplémentaires sont nécessaires pour prévenir l'exposition au froid et les blessures qui en découlent chez les personnes en situation d'itinérance.

OBJECTIVE: To estimate the rates of diabetes complications and revascularization procedures among people with diabetes who have experienced homelessness compared with a matched cohort of nonhomeless control subjects. RESEARCH DESIGN AND METHODS: A propensity-matched cohort study was conducted using administrative health data from Ontario, Canada. Inclusion criteria included a diagnosis of diabetes and at least one hospital encounter between April 2006 and March 2019. Homeless status was identified using a validated administrative data algorithm. Eligible people with a history of homelessness were matched to nonhomeless control subjects with similar sociodemographic and clinical characteristics. Rate ratios (RRs) for macrovascular complications, revascularization procedures, acute glycemic emergencies, skin/soft tissue infections, and amputation were calculated using generalized linear models with negative binomial distribution and robust SEs. RESULTS: Of 1,076,437 people who were eligible for inclusion in the study, 6,944 were identified as homeless. A suitable nonhomeless match was found for 5,219 individuals. The rate of macrovascular complications was higher for people with a history of homelessness compared with nonhomeless control subjects (RR 1.85, 95% CI 1.64-2.07), as were rates of hospitalization for glycemia (RR 5.64, 95% CI 4.07-7.81) and skin/soft tissue infections (RR 3.78, 95% CI 3.31-4.32). By contrast, the rates of coronary revascularization procedures were lower for people with a history of homelessness (RR 0.76, 95% CI 0.62-0.94). CONCLUSIONS: These findings contribute to our understanding of the impact of homelessness on long-term diabetes outcomes. The higher rates of complications among people with a history of homelessness present an opportunity for tailored interventions to mitigate these disparities.

Importance: Few interventions are proven to reduce total health care costs, and addressing cost-related nonadherence has the potential to do so. Objective: To determine the effect of eliminating out-of-pocket medication fees on total health care costs. Design, Setting, and Participants: This secondary analysis of a multicenter randomized clinical trial using a prespecified outcome took place across 9 primary care sites in Ontario, Canada (6 in Toronto and 3 in rural areas), where health care services are generally publicly funded. Adult patients (≥18 years old) reporting cost-related nonadherence to medicines in the past 12 months were recruited between June 1, 2016, and April 28, 2017, and followed up until April 28, 2020. Data analysis was completed in 2021. Interventions: Access to a comprehensive list of 128 medicines commonly prescribed in ambulatory care with no out-of-pocket costs for 3 years vs usual medicine access. Main Outcome and Measures: Total publicly funded health care costs over 3 years, including costs of hospitalizations. Health care costs were determined using administrative data from Ontario's single-payer health care system, and all costs are reported in Canadian dollars with adjustments for inflation. Results: A total of 747 participants from 9 primary care sites were included in the analysis (mean [SD] age, 51 [14] years; 421 [56.4%] female). Free medicine distribution was associated with a lower median total health care spending over 3 years of $1641 (95% CI, $454-$2792; P = .006). Mean total spending was $4465 (95% CI, -$944 to $9874) lower over the 3-year period. Conclusions and Relevance: In this secondary analysis of a randomized clinical trial, eliminating out-of-pocket medication expenses for patients with cost-related nonadherence in primary care was associated with lower health care spending over 3 years. These findings suggest that eliminating out-of-pocket medication costs for patients could reduce overall costs of health care. Trial Registration: ClinicalTrials.gov Identifier: NCT02744963.

In response to the COVID-19 pandemic, the City of Toronto opened temporary shelter hotels with on-site supports for people previously living on the street, in encampments or in emergency shelters. The Beyond Housing program was created to enhance service offerings in the shelter hotel system and to support people not engaging with services. Using a Housing First approach, Beyond Housing offers three main interventions: (1) case management, (2) care coordination and (3) on-site and community-based mental health and social supports. This commentary explores the strengths and challenges of implementing Beyond Housing within temporary shelter hotels, and then discusses the lessons learned.

Importance: People experiencing homelessness are at high risk of SARS-CoV-2 infection. Incident infection rates have yet to be established in these communities and are needed to inform infection prevention guidance and related interventions. Objective: To quantify the SARS-CoV-2 incident infection rate among people experiencing homelessness in Toronto, Canada, in 2021 and 2022 and to assess factors associated with incident infection. Design, Setting, and Participants: This prospective cohort study was conducted among individuals aged 16 years and older who were randomly selected between June and September 2021 from 61 homeless shelters, temporary distancing hotels, and encampments in Toronto, Canada. Exposures: Self-reported housing characteristics, such as number sharing living space. Main Outcomes and Measures: Prevalence of prior SARS-CoV-2 infection in summer 2021, defined as self-reported or polymerase chain reaction (PCR)- or serology-confirmed evidence of infection at or before the baseline interview, and SARS-CoV-2 incident infection, defined as self-reported or PCR- or serology-confirmed infection among participants without history of infection at baseline. Factors associated with infection were assessed using modified Poisson regression with generalized estimating equations. Results: The 736 participants (415 of whom did not have SARS-CoV-2 infection at baseline and were included in the primary analysis) had a mean (SD) age of 46.1 (14.6) years; 486 (66.0%) self-identified as male. Of these, 224 (30.4% [95% CI, 27.4%-34.0%]) had a history of SARS-CoV-2 infection by summer 2021. Of the remaining 415 participants with follow-up, 124 experienced infection within 6 months, representing an incident infection rate of 29.9% (95% CI, 25.7%-34.4%), or 5.8% (95% CI, 4.8%-6.8%) per person-month. Report after onset of the SARS-CoV-2 Omicron variant was associated with incident infection, with an adjusted rate ratio (aRR) of 6.28 (95% CI, 3.94-9.99). Other factors associated with incident infection included recent immigration to Canada (aRR, 2.74 [95% CI, 1.64-4.58]) and alcohol consumption over the past interval (aRR, 1.67 [95% CI, 1.12-2.48]). Self-reported housing characteristics were not significantly associated with incident infection. Conclusions and Relevance: In this longitudinal study of people experiencing homelessness in Toronto, SARS-CoV-2 incident infection rates were high in 2021 and 2022, particularly once the Omicron variant became dominant in the region. Increased focus on homelessness prevention is needed to more effectively and equitably protect these communities.

BACKGROUND: Continuity of primary care (CPC) is associated with reduced mortality and improved health status. This study assessed the level of CPC and changes in CPC over 6 years among adults with experience of homelessness and mental illness who received a Housing First intervention. METHODS: Participants were adults (≥18 years old) with a serious mental disorder and experiencing chronic homelessness enrolled between October 2009 and June 2011 in the Toronto site of the Canadian At Home/Chez Soi study and followed until March 2017. Participants were randomized to Housing First with intensive case management (HF-ICM), Housing First with assertive community treatment (HF-ACT), or treatment as usual. For this report, 280 intervention group participants (HF-ICM, n = 193 and HF-ACT, n = 87) were analysed using data from health records. The main outcome was CPC measured by the Continuity of Care Index as a continuous and categorical variable among participants during 3 consecutive 2-year periods. RESULTS: Most HF-ICM participants had low levels of CPC, with 68%-74% of this group having low CPC across all time periods. Similarly, most HF-ACT participants had low levels of CPC, with 63%-78% of this group having low CPC across all time periods. CONCLUSIONS: Among this group of individuals with mental illness who were experiencing homelessness, CPC remained low over 6 years of follow-up. This study highlights that housing and mental health interventions may need to place greater emphasis on improving CPC using effective strategies that are specifically geared towards this important goal among their clients.
