Effect of the Covid-19 pandemic on initiations of opioid agonist therapy in Ontario
BACKGROUND: Maintaining access to opioid agonist therapy (OAT) was a key concern at the COVID-19 pandemic onset. Consequently, Ontario introduced guidance for changes to OAT delivery, including relaxed take-home dosing and expanded virtual care. We examined how the pandemic influenced OAT initiation trends. METHODS: We conducted a population-based, retrospective interrupted time series analysis using linked administrative health data from March 2…

“Everybody is impacted. Everybody's hurting”
Our study highlights opportunities for organizational practices that better support harm reduction workers, including formal emotional supports and community-based supportive care services. Improvement to the socio-economic-political determinants of work such as adequate compensation and access to full benefit packages are also needed in the harm reduction sector for all workers
Trends in opioid toxicities among people with and without opioid use disorder and the impact of the Covid-19 pandemic in Ontario, Canada
The rate of opioid toxicities accelerated across Ontario following the pandemic-related state of emergency, with the majority of this increase among people with OUD. The important differences observed among people with OUD compared with those without, highlights the critical need for improved access to harm reduction and treatment interventions among this population

Spotting as a risk mitigation method
“They have their security, we have our community”
Unaffordable housing is a growing crisis in Canada, exacerbated by the COVID-19 pandemic, yet perspectives of people living outdoors in encampments have primarily gone unheard. We conducted qualitative interviews with encampment residents to explore how mutual support occurred within the social context of encampments. We found that mutually supportive interactions helped residents meet basic survival needs, as well as health and social needs, and…

How simulation modeling can support the public health response to the opioid crisis in North America
Challenges, Skepticism, and Recommendations from Police about Working in Collaboration with Supervised Consumption Services
Background The operation of supervised consumption services (SCS), programs that offer supervised locations for the consumption of drugs such as heroin, other opioids, cocaine, other stimulants, and other drugs, is contingent on cooperative relationships with police. In this manuscript, we focus on an under studied topic: how active duty police officers understand their role with respect to SCS, and their recommendations for improving relationshi…
‘This is a health service. Leave it alone’
Background While sanctioned supervised consumption services (SCS) – monitored spaces where people can consume drugs – are exempt from drug law enforcement, local police interact with SCS in the course of their duties. Policies and protocols to guide SCS–police relationships vary internationally, but appear to be lacking in some jurisdictions.Methods We conducted focus groups with service users (n = 24) and staff (n = 21) at the first three legall…
Health-related quality of life in neonates and infants
It's our safe sanctuary’
The unsanctioned OPS in Toronto served an important role in defining new, community-led, flexible responses to opioid overdose-related deaths at a time of markedly increasing mortality. Providing harm reduction services in diverse settings and expanding services to include smoking and assisted injection may increase access for marginalized people who use drugs
Assessing Timely Presentation to Care Among People Diagnosed with HIV During Hospital Admission
Timely presentation to care for people newly diagnosed with HIV is critical to optimize health outcomes and reduce onward HIV transmission. Studies describing presentation to care following diagnosis during a hospital admission are lacking. We sought to assess the timeliness of presentation to care and to identify factors associated with delayed presentation. We conducted a population-level study using health administrative databases. Participant…

Trends in the awareness, acceptability, and usage of HIV pre-exposure prophylaxis among at-risk men who have sex with men in Toronto
To maximize its potential public health benefits, PrEP scale-up strategies must address self-perceived HIV risk and increase access to PrEP providers
Risk creating and risk reducing
Progressive public health authorities in high-income countries have advocated supervised consumption facilities, where people who use illicit drugs can consume them in a hygienic, supervised environment, as a way of reducing drug-related risks to both people who use drugs and communities. However, the planning of such facilities has often met with strong reactions from the local community. ‘Not in my backyard’ (NIMBY) type reactions are frequentl…

Informing Targeted Interventions to Optimize the Cascade of HIV Care Using Cluster Analyses of Health Resource Use Among People Living with HIV/Aids
A glossary of terms for understanding political aspects in the implementation of Health in All Policies (HiAP)
Health in All Policies (HiAP) is a strategy that seeks to integrate health considerations into the development, implementation and evaluation of policies across various non-health sectors of the government. Over the past 15 years, there has been an increase in the uptake of HiAP by local, regional and national governments. Despite the growing popularity of this approach, most existing literature on HiAP implementation remains descriptive rather t…
Temporal Trends in the Use of Investigations After Stroke or Transient Ischemic Attack
BACKGROUND: Guidelines recommend that patients with stroke or transient ischemic attack (TIA) undergo neuroimaging and cardiac investigations to determine etiology and guide treatment. It is not known how the use of these investigations has changed over time and whether there have been associated changes in management. OBJECTIVES: To evaluate temporal trends in the use of brain and vascular imaging, echocardiography, and antithrombotic and surgic…

Employment status is associated with both physical and mental health quality of life in people living with HIV
To evaluate the relationship between employment status and health-related quality of life (HRQOL) in HIV/AIDS. A total of 361 participants provided baseline data in the context of an ongoing cohort study examining the natural history of neurobehavioral functioning and its effects on HRQOL. We administered tests and collected laboratory data to determine demographic status, HIV disease markers, psychosocial symptom burden, neurocognitive function …

Adverse quality of life consequences of antiretroviral medications
To identify the effects of antiretroviral therapy on quality of life, we performed a qualitative content analysis of the Medical Outcomes Study-Human Immunodeficiency Virus (MOS-HIV) Health Survey. We used focus groups to elicit views about antiretroviral effects on quality of life from a purposive sample of treatment-experienced participants. Data were analysed using a grounded theory approach. We appraised the content of the MOS-HIV against the…

Relationships Between Dimensions of Disability Experienced by Adults Living with HIV
Labor Force Participation and Health-Related Quality of Life in HIV-Positive Men Who Have Sex with Men
Design considerations for supervised consumption facilities (SCFs)
Community Engagement in Health Status Instrument Development
The HDQ is the first HIV-specific questionnaire to describe disability experienced by adults with HIV. Engaging community research partners in the development of the HDQ enhanced the questionnaire's relevance, feasibility, and face and content validities. This approach may be considered by others interested in health status instrument development
Adequacy of prenatal care among women living with human immunodeficiency virus
Despite universal health care, disparities exist in the receipt of adequate prenatal care between women living with and without HIV. Interventions are required to ensure that women with HIV receive timely and adequate prenatal care
Economic considerations and health in all policies initiatives
Our results are useful for elaborating propositions for use in realist multiple explanatory case studies. First, we propose that economic considerations are currently used primarily as a method by health sectors to promote and legitimize HiAP to non-health sectors with the goal of securing resources for HiAP. Second, allocating resources and making funding decisions regarding HiAP are inherently political acts that reflect tensions within governm…
