Objective: To examine the prevalence and profile of people with co-occurring mental and substance use disorders in relation to numerous demographic, diagnostic, and needs-related variables across a comprehensive system of mental health services using a standard methodology.Method: Data were collected on cases (n = 9839) sampled from specialty tertiary inpatient, specialty outpatient, and community-based mental health programs. Status with respect to co-occurring disorders was based on recorded diagnosis of substance use disorder and the substance abuse measure within the Colorado Client Assessment Record. The demographic and needs profile was compared across groups with or without co-occurring disorders within each level of care.Results: Overall, the prevalence of co-occurring disorders was 18.5%, and highest among clients receiving specialty tertiary inpatient care (28%), and within selected subpopulations such as younger adults (55%) and those with personality disorders (34%). There were few differences between groups based on co-occurring disorders in the specialty inpatient programs. For outpatient and community settings, the clients with co-occurring disorders were distinguished by a more impaired and complex needs profile and more likely to be young, single, male, and of low education. Across all levels of care, having a co-occurring disorder was strongly associated with antisocial and challenging behaviour, legal involvement, and risk of suicide or self-harm. Conclusion:The prevalence estimate of co-occurring disorders is likely representative of a multilevel system of care that serves a large, mixed urban and rural population. Results highlight the need to focus on specific subpopulations and sectors in pursuit of more integrated treatment and support for their mental health and addictions problems. Can J Psychiatry 2008;53(12):810-821Clinical Implications · Clinicians can use sociodemographic characteristics, such as male sex, younger age, and being unemployed, and clinical indicators, such as overall mental health severity and behavioural challenges, to help identify and support people with substance use disorders. · Treatment and support models for co-occurring mental and substance use disorders must include risk management strategies, given the higher prevalence of challenging behaviours within this population. · There is a need for system-wide planning regarding co-occurring mental and substance use disorders. Limitations· Although findings were based on a comprehensive mental health system, the results may not be applicable to every jurisdiction. · Study findings should not necessarily be generalized to acute care, consumer, or peer support programs because they were not included in our study. · Clinical diagnostic interviews were not feasible to validate study criteria for defining co-occurring disorders.
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.
Substance use and abuse decreased significantly after 12 months of EI services; EI services may be able to detect and to reduce substance use among FEP patients before it becomes a more serious disorder.
Background The aim of this paper was to examine the early impact of COVID-19 on substance use to assess implications for planning substance use treatment and support systems. Method A systematic review of literature published up to March 2021 was conducted to summarize changes in prevalence, incidence, and severity of substance use associated with COVID-19 and the accompanying public health measures, including lockdown, stay-at-home orders, and social distancing. Results We identified 53 papers describing changes to substance use at the population level. The majority of papers described changes related to alcohol use and most relied on self-reported measures of consumption during the COVID-19 pandemic, compared with pre-pandemic use. There was less evidence to support changes in non-alcohol substance use. In general, risky pre-pandemic alcohol use, caregiving responsibilities, stress, depression, anxiety, and current treatment for a mental disorder were found to be associated with increased substance use. Conclusion This review provides preliminary data on changes in substance use, indicating that certain segments of the population increased their alcohol use early on in the COVID-19 pandemic and may be at greater risk of harm and in need of additional services. There is a need for additional population-level information on substance use to inform evidence-based rapid responses from a treatment system perspective.
The differential use of services, satisfaction, and unmet need across diagnostic status allowed for speculation on differing levels of disability and stigma in the help-seeking process for different types of disorders. The strong association between co-occurring disorders and unmet need for care, including a large proportion of respondents who stated they preferred to self-manage their symptoms, is particularly troubling and deserves future research attention.
The findings highlight potential problems for individuals with mental and substance use disorders in accessing services. The elevated occurrence of perceived unmet need appeared to be relatively less affected by contact with the health care system than by generalized distress and problem severity. Issues such as stigma, motivation, and satisfaction with past services may influence help-seeking patterns and perceptions of unmet need and should be examined in future work.
In this article we discuss the findings from a series of focus groups conducted as part of a 3-year, mixed-method evaluation of clinical programs in a large mental health and substance use treatment facility in Canada. We examined the perceptions of clinical personnel on the physical design of new treatment units and the impact on service delivery and the work environment. The new physical design appeared to support client recovery and reduce stigma; however, it brought certain challenges. Participants reported a compromised ability to monitor clients, a lack of designated therapeutic spaces, and insufficient workspace for staff. They also thought that physical design positively facilitated communication and therapeutic relationships among clinicians and clients, and increased team cohesion. We suggest that, from these findings, new avenues for research on achieving the important balance between client and staff needs in health facility design can be explored.
