Objective: Population health surveys around the world have studied the epidemiology of comorbid substance use disorders (SUDs) and other mental disorders as part of larger efforts to assess needs and direct integrated planning and delivery of services. This study presents the first national assessment in Canada of the prevalence of co-occurring SUDs and other mental disorders, with attention to differences by substance problem severity, sex, age, and region. Methods: This work is a secondary analysis of data from the 2002 Canadian Community Health Survey: Mental Health and Well-Being. The sample was obtained using a multistage stratified cluster design ( n = 36 984, response rate = 77%). Results: The 12-month population prevalence of co-occurring disorders was 1.7%. The 12-month prevalence of other mental disorders was higher among those with illicit drug, relative to alcohol, problems and among those with dependence, compared with those with less severe problems. Sex and age differences mirrored population differences in pure disorders. Salient regional differences included the higher rate of co-occurring disorders in British Columbia and the lower rates in Quebec. Conclusions: Cross-study comparisons are hampered by methodological differences; however, these Canadian rates are at the lower end of the range reported internationally. This might have resulted from the exclusion of several disorders known to be highly comorbid with SUDs. Nonetheless, prevalence is high in certain subgroups, and efforts under way to improve Canada's substance abuse and mental health services should continue to ensure that adequate attention is directed to the needs of people with co-occurring disorders.

BackgroundDrug use is associated with increased morbidity and mortality but people who use drugs experience significant barriers to care. Data are needed about the care experiences of people who use drugs to inform interventions and quality improvement initiatives. The objective of this study is to describe and characterize the experience of acute care for people who use drugs.MethodsWe conducted a qualitative descriptive study. We recruited people with a history of active drug use at the time of an admission to an acute care hospital, who were living with HIV or hepatitis C, in Toronto and Ottawa, Canada. Data were collected in 2014 and 2015 through semi-structured interviews, audio-recorded and transcribed, and analyzed thematically.ResultsTwenty-four adults (18 men, 6 women) participated. Participants predominantly recounted experiences of stigma and challenges accessing care. We present the identified themes in two overarching domains of interest: perceived effect of drug use on hospital care and impact of care experiences on future healthcare interactions. Participants described significant barriers to pain management, often resulting in inconsistent and inadequate pain management. They described various strategies to navigate access and receipt of healthcare from being “an easy patient” to self-advocacy. Negative experiences influenced their willingness to seek care, often resulting in delayed care seeking and targeting of certain hospitals.ConclusionDrug use was experienced as a barrier at all stages of hospital care. Interventions to decrease stigma and improve our consistency and approach to pain management are necessary to improve the quality of care and care experiences of those who use drugs.

Background: Supervised consumption services (SCS) are being implemented across Canada in response to a variety of drug-related harms. We explored the implementation context of newly established SCS in Toronto and the role of policing in shaping program access by people who inject drugs (PWID). Methods: We conducted one-to-one qualitative semi-structured interviews with 24 PWID. Participants were purposively recruited. Ethnographic observations were conducted at each of the study sites as well as in their respective neighbourhoods. Relevant policy documents were also reviewed. Results: Policing was overwhelmingly discussed by participants from both SCS sites. However, participant responses varied depending on the site in question. Subthemes from participant responses on policing at site #1 described neighbourhood police presence and fears of police harassment and drug arrests before, during, or after accessing SCS. Conversely, subthemes from participant responses on policing at site #2 described immunity and protection from police while using the SCS, as well as a lack of police presence or fears of police harassment and arrests. These differences in implementation contexts were largely shaped by differences in local neighbourhoods and drug scenes. Police policies highlighted federal laws protecting PWID within SCS, but also the exercise of discretion when applying the rule of law outside of these settings. Conclusions: Participants' perspectives on, and experiences with, policing as they relate to accessing SCS were shaped by the implementation contexts of each SCS site and how neighbourhoods, drug scenes, and differences in policing practices affected service use. Our findings also demonstrate the disconnect between the goals of policing and those of SCS. Until larger structural barriers are addressed (e.g. criminalization), future SCS programming should consider the impact of policing on the SCS implementation context to improve client experience with, and access to, SCS.
