Use of mental health care services by Canadians with co-occurring substance dependence and mental disorders

Adult self-reported childhood maltreatment types are associated with treatment satisfaction and alcohol relapse in patients with comorbid substance use and mental health disorders

BACKGROUND AND OBJECTIVES

Individuals with comorbid substance use and mental health disorders (concurrent disorders; CD) report poor treatment outcomes, high prevalence of childhood maltreatment, and mostly negative experiences with treatment. No studies to date have examined childhood maltreatment and treatment outcomes in CD. This study investigated self-reported childhood maltreatment as it relates to treatment satisfaction and substance use relapse among CD patients.

METHODS

The 258 CD inpatients completed a self-report questionnaire package, comprising the Childhood Trauma Questionnaire and the Inpatient Consumer Survey (ICS). Childhood maltreatment was assessed according to five subtypes and self-perceived treatment satisfaction was rated across six ICS domains. Psychiatric diagnoses, substance use status and relapse data were retrieved via patient medical charts.

RESULTS

Emotional neglect was associated with lower ratings across all ICS domains and physical neglect was associated with a lower rating for 'outcome of care'. Childhood sexual abuse was associated with a greater likelihood of alcohol relapse. No other relationships were statistically significant.

DISCUSSION AND CONCLUSIONS

The presence of childhood neglect (but not abuse) was more associated with overall treatment dissatisfaction, and sexual abuse alone increased the likelihood of alcohol relapse. These findings suggest some early adverse experiences in CD patients may increase negative experiences in treatment while others contribute to the risk of substance use. Broader longitudinal research is needed to examine the trajectory leading to negative outcomes.

SCIENTIFIC SIGNIFICANCE

This is the first study to report differential patterns of association by type of childhood maltreatment on negative outcomes in treatment among CD patients.

Physician perspective on the implementation of risk mitigation strategies when prescribing opioid medications: a qualitative analysis

OBJECTIVE

To understand the physician perspective on the barriers and facilitators of implementing nine different opioid risk mitigation strategies (RMS) when prescribing opioid medications.

METHODS

We created and dispersed a cross-sectional online survey through the Qualtrics© data collection platform among a nationwide sample of physicians licensed to practice medicine in the United States who have prescribed an opioid medication within the past year. The responses were analyzed using a deductive thematic analysis approach based on the Consolidated Framework for Implementation Research (CFIR) to ensure a holistic approach to identifying the barriers and facilitators for each RMS assessed. In concordance with this method, the themes and codes for the thematic analysis were defined prior to the analysis. The five domains within the CFIR were used as themes and the 39 nested constructs were treated as the codes. Two members of the research team independently coded the transcripts and discussed points of disagreement until consensus was reached. All analyses were conducted in ATLAS.ti© V7.

RESULTS

The completion rate for this survey was 85.1% with 273 participant responses eligible for analysis. Intercoder reliability was calculated to be 82%. Deductive thematic analysis yielded 2,077 descriptions of factors affecting implementation of the nine RMS. The most salient code across all RMS was Knowledge and Beliefs about the Intervention, which refers to individuals' attitudes towards and value placed on the intervention. Patient Needs and Resources, a code referring to the extent to which patient needs are known and prioritized by the organization, also emerged as a salient code. The physicians agreed that the patient perspective on the issue is vital to the uptake of each of the RMS.

CONCLUSIONS

This deductive thematic analysis identified key points for actionable intervention across the nine RMS assessed and established the importance of patient concordance with physicians when deciding on a course of treatment.

Psychological distress, non-medical use of prescription medications, and perceived unmet mental health care needs: a cross-sectional study of Ontario students

PURPOSE

The non-medical use of prescription medications among adolescents has become a concerning public health issue. This study assessed the prevalence of the non-medical use of prescription medications in Ontario high school students, and explored the moderating effect of this use on the relationship between psychological distress and unmet mental health needs.

METHODS

Cross-sectional data for 4896 students, age 14-18, were drawn from the 2019 Ontario Student Drug Use and Health Survey. Psychological distress was measured using the Kessler-6 Distress Scale, unmet mental health needs were defined by self-report (yes/no), and non-prescription medication use was defined by self-reported frequency of use. Using logistic regression, we explored the effect of the non-medical use of prescription medications on the relationship between psychological distress and unmet mental health needs.

RESULTS

High proportions of Ontario students reported serious psychological distress (22%), some degree of unmet mental health need (38%), and/or non-medical use of prescription medications (13%). While there were strong associations between psychological distress and unmet mental health need, this association was weaker among those reporting non-medical use of prescription medications (OR = 3.3, 95% CI 1.9-5.7) compared to non-users (OR = 5.6, 95% CI 4.5-7.1).

CONCLUSION

Our findings suggest that Ontario students experiencing distress and using non-prescribed medications are less likely to identify a need for mental health support, highlighting the consequences of apparent self-medication through misuse of prescription medications. To assist in the redirection of adolescent perceptions of healthy coping strategies, population-based educational programming, with targeted promotion of both formal and informal mental health care resources, should be considered.

Trends in Involuntary Psychiatric Hospitalization in British Columbia: Descriptive Analysis of Population-Based Linked Administrative Data from 2008 to 2018

INTRODUCTION

Involuntary psychiatric hospitalization occurs when someone with a serious mental disorder requires treatment without their consent. Trends vary globally, and currently, there is limited data on involuntary hospitalization in Canada. We examine involuntary hospitalization trends in British Columbia, Canada, and describe the social and clinical characteristics of people ages 15 and older who were involuntarily hospitalized between 2008/2009 and 2017/2018.

METHOD

We used population-based linked administrative data to examine and compare trends in involuntary and voluntary hospitalizations for mental and substance use disorders. We described patient characteristics (sex/gender, age, health authority, income, urbanity/rurality, and primary diagnosis) and tracked the count of involuntarily hospitalized people over time by diagnosis. Finally, we examined population-based prevalence over time by age and sex/gender.

RESULTS

Involuntary hospitalizations among British Columbians ages 15 and older rose from 14,195 to 23,531 (65.7%) between 2008/2009 and 2017/2018. Apprehensions involving police increased from 3,502 to 8,009 (128.7%). Meanwhile, voluntary admissions remained relatively stable, with a minimal increase from 17,651 in 2008/2009 to 17,751 in 2017/2018 (0.5%). The most common diagnosis for involuntary patients in 2017/2018 was mood disorders (25.1%), followed by schizophrenia (22.3%), and substance use disorders (18.8%). From 2008/2009 to 2017/2018, the greatest increase was observed for substance use disorders (139%). Over time, population-based prevalence increased most rapidly among women ages 15-24 (162%) and men ages 15-34 (81%) and 85 and older (106%).

CONCLUSION

Findings highlight the need to strengthen the voluntary care system for mental health and substance use, especially for younger adults, and people who use substances. They also signal a need for closer examination of the use of involuntary treatment for substance use disorders, as well as further research exploring forces driving police involvement and its implications.

The relationship between mood disorder diagnosis and experiencing an unmet health-care need in Canada: findings from the 2014 Canadian Community Health Survey

BACKGROUND

Despite Canada's universal health-care system, millions of Canadians experience unmet health-care needs (UHCN). People with mood disorders may be at higher risk of UHCN due to barriers such as stigma and gaps in health-care services.

AIM

We aimed to examine the relationship between having a diagnosed mood disorder and experiencing UHCN using a recent, nationally representative survey.

METHODS

Using the 2014 Canadian Community Health Survey, we used multivariate logistic regression to estimate the association between mood disorder and UHCN in the past 12 months, adjusting for sociodemographic variables and health status.

RESULTS

Among 52,825 respondents, 11.8% reported UHCN. Respondents with a diagnosed mood disorder were more likely to report UHCN [adjusted odds ratio (OR) 1.61, 95% confidence interval (CI) 1.38, 1.89]. Among respondents with a regular doctor, people with mood disorders were still more likely to report UHCN (OR 1.63, 95% CI 1.38, 1.93). Sensitivity analyses using propensity score and missing data imputation approaches resulted in similar estimates.

CONCLUSIONS

Adults diagnosed with a mood disorder are more likely to report UHCN in the past year, even those with a regular doctor. Our findings suggest that barriers beyond physician attachment may impact access to care for people with mood disorders.

Coping and Co-Occurrence of Gaming Disorder and Substance Use in Recovering Substance Users

BACKGROUND

There are a wide range of negative effects associated with both substance use disorders and behavioural disorders and their co-occurrence. Understanding the way in which at-risk populations (e.g., substance-abstinent users) interact with potentially addictive behaviours (e.g., gaming) and substance use-while navigating life stressors through differing coping styles-can inform preventative strategies.

METHODS

Therefore, the present study investigated 64 clinical participants and 138 general population participants. Each cohort was required to complete a battery of psychometric scales exploring problematic behaviours, problematic substance use, co-occurrence, and coping styles. Additional exploratory direct comparisons of gamers in the clinical cohort and gamers in the general cohort were carried out.

RESULTS

The study's findings suggest that gamers from different populations (i.e., general and clinical) share similar at-risk behaviours. These problematic behaviours were more pronounced among abstinent substance use gamers, and more specifically among poly-substance use gamers.

CONCLUSIONS

The findings of the present study add to the literature and suggest that dysfunctional coping style and the co-occurrence of problematic behaviours may have an impact on the assessment and potential treatment of substance abstinent gamers. The findings offer support for an integrated treatment approach, wherein both substance use and the other problematic behaviours (e.g., gaming) are considered in tandem.

Co-Occurrence of Gaming Disorder and Other Potentially Addictive Behaviours between Australia, New Zealand, and the United Kingdom

Background: Evidence suggests that gamers can have varying experiences of disordered gaming behaviours due to coping mechanisms and how they can act as risk or protective factor in the development and/or maintenance of disordered behaviours. A particular area of interest is how this may manifest across different countries. Understanding the interplay of these potential risk and protective factors within different countries will aid identifying and preventing disordered behaviours. Methods: Three cohorts were recruited from Australia, New Zealand, and the United Kingdom. Each cohort was required to complete a battery of psychometric scales exploring problematic behaviours, problematic substance use, co-occurrence, coping styles, and personality. A latent profile analysis was conducted to examine the differences between cohorts and further investigated with additional analyses. Results: The findings suggested that a minority of gamers were affected by gaming disorder, and there appeared an at-risk cohort who utilise gaming as a maladaptive coping strategy. Other accompanying potentially addictive behaviour or substance use may be exacerbated as a result, the manifestation of which can be influenced by cultural elements. Conclusions: When considering gamers from countries which hold similar views, it is important to be cognisant of the variations found in the manifestations of disordered gaming and accompanying potentially addictive behaviours. This will allow for a more precise identification of at-risk behaviours, which will result in more favourable treatment outcomes for those who are considered at-risk or high-risk individuals.

The relationship between outpatient service use and emergency department visits among people treated for mental and substance use disorders: analysis of population-based administrative data in British Columbia, Canada

Background

Research findings on the association between outpatient service use and emergency department (ED) visits for mental and substance use disorders (MSUDs) are mixed and may differ by disorder type.

Methods

We used population-based linked administrative data in British Columbia, Canada to examine associations between outpatient primary care and psychiatry service use and ED visits among people ages 15 and older, comparing across people treated for three disorder categories: common mental disorders (MDs) (depressive, anxiety, and/or post-traumatic stress disorders), serious MDs (schizophrenia spectrum and/or bipolar disorders), and substance use disorders (SUDs) in 2016/7. We used hurdle models to examine the association between outpatient service use and odds of any ED visit for MSUDs as well count of ED visits for MSUDs, stratified by cohort in 2017/8.

Results

Having had one or more MSUD-related primary care visit was associated with lower odds of any ED visit among people treated for common MDs and SUDs but not people treated for serious MDs. Continuity of primary care was associated with slightly lower ED use in all cohorts. One or more outpatient psychiatrist visits was associated with lower odds of ED visits among people treated for serious MDs and SUDs, but not among people with common MDs.

Conclusion

Findings highlight the importance of expanded access to outpatient specialist mental health services, particularly for people with serious MDs and SUDs, and collaborative models that can support primary care providers treating people with MSUDs.

Prevalence and Correlates of Illicit Substance Use Among Young Adults Experiencing Homelessness in Seven Cities Across the United States

Background

Young adults experiencing homelessness (YAEH) engage in substantially higher substance use rates than housed young adults. This current study builds on previous research by investigating the prevalence of and salient correlates of illicit substance use across a seven-city sample.

Methods

This study used the Homeless Youth Risk and Resiliency Survey (HYRRS) dataset, n=1426 Young adults experiencing homelessness to study patterns and correlates of illicit substance use.

Results

Multivariate logistic regression analyses were used to assess correlates of substance use. Study site, age, gender identity, sexual orientation, history of suicidal ideation, use of specific substances, and trading sex for drugs were associated with five types of illicit substance use (ecstasy, cocaine, crack, methamphetamine, and injection drug use).

Conclusion

Findings indicate that substance use interventions for YAEH must be multifaceted, addressing illicit and multiple substance use, along with the myriad factors associated with substance use among this at-risk group.

Preferences for research design and treatment of comorbid depression among patients with an opioid use disorder: A cross-sectional discrete choice experiment

BACKGROUND

Up to 74 % of people with an opioid use disorder (OUD) will experience depression in their lifetime. Understanding and addressing the concept of preference for depression treatments and clinical trial designs may serve as an important milestone in enhancing treatment and research outcomes. Our goal is to evaluate preferences for depression treatments and clinical trial designs among individuals with an OUD and comorbid depression.

METHODS

We evaluated preferences for depression treatments and clinical trial designs using an online cross-sectional survey including a best-best discrete choice experiment. We recruited 165 participants from opioid agonist treatment clinics and community-based services in Calgary, Charlottetown, Edmonton, Halifax, Montreal, Ottawa, Quebec City, St. John's and Trois-Rivières, Canada.

RESULTS

Psychotherapy was the most accepted (80.0 %; CI: 73.9-86.1 %) and preferred (31.5 %; CI: 24.4-38.6 %) treatment. However, there was a high variability in acceptability and preferences of depression treatments. Significant predictors of choice for depression treatments were administration mode depending on session duration (p < 0.001), access mode (p < 0.001) and treatment duration (p < 0.001). Significant predictors of choice for clinical trial designs were allocation type (p = 0.008) and monetary compensation (p = 0.033). Participants preferred participating in research compared to non-participation (p < 0.001).

CONCLUSIONS

Accessibility and diversity of depression interventions, including psychotherapy, need to be enhanced in addiction services to ensure that all patients can receive their preferred treatment. Ensuring proper monetary compensation and comparing an intervention of interest with an active treatment might increase participation of depressed OUD patients in future clinical research initiative.

Examination of referral source and retention among women in residential substance use disorder treatment: a prospective follow-up study

Background

Court-mandated substance use disorder (SUD) treatment, as compared to nonmandated treatment, has been associated with increased retention and completion. However, whether child protective services (CPS)-mandated women’s residential SUD treatment leads to improved treatment retention in comparison to criminal justice (CJ)-mandated and nonmandated treatment remains unclear.

Purpose

This study compared the number of days retained in residential SUD treatment among three referral sources (CPS, CJ, and nonmandated), while also examining whether having a co-occurring mental health disorder or increased stress, depression, anxiety, and PTSD symptomology contributed to decreased retention. This study tested the hypothesis that women mandated by the CPS and CJ systems would have improved residential SUD treatment retention compared with nonmandated women.

Methods

Multiple regression analyses were conducted on data for a diverse sample of 245 women (Hispanic: N = 141, Black: N = 50, White: N = 50) mandated or nonmandated (CJ: N = 114, CPS: N = 82, nonmandated: N = 49) into residential SUD treatment to determine each group’s treatment retention outcomes. Results: Women mandated to SUD residential treatment by the CPS system remained in treatment significantly longer (p = .046), compared to women not mandated, representing a 34.4% increase in retention. Findings further revealed a corresponding 2.3% decrease in retention (p = .048) for each one-unit increase in a patient’s stress score, whereas those with a co-occurring mental health diagnosis had a 43.6% decrease in SUD treatment retention (p < .001).

Conclusions

Policy and clinical considerations include (a) increasing case management support and wraparound services that meet the multiple service needs of women who are nonmandated to residential SUD treatment, and (b) incorporating a more nuanced treatment approach that manages mental health disorders and stress symptomology early in treatment when women are most vulnerable to relapse and treatment dropout.

Typology of patients who use emergency departments for mental and substance use disorders

BACKGROUND

Identifying profiles of people with mental and substance use disorders who use emergency departments may help guide the development of interventions more appropriate to their particular characteristics and needs.

AIMS

To develop a typology for the frequency of visits to the emergency department for mental health reasons based on the Andersen model.

METHOD

Questionnaires were completed by patients who attended an emergency department (n = 320), recruited in Quebec (Canada), and administrative data were obtained related to sociodemographic/socioeconomic characteristics, mental health diagnoses including alcohol and drug use, and emergency department and mental health service utilization. A cluster analysis was performed, identifying needs, predisposing and enabling factors that differentiated subclasses of participants according to frequency of emergency department visits for mental health reasons.

RESULTS

Four classes were identified. Class 1 comprised individuals with moderate emergency department use and low use of other health services; mostly young, economically disadvantaged males with substance use disorders. Class 2 comprised individuals with high emergency department and specialized health service use, with multiple mental and substance use disorders. Class 3 comprised middle-aged, economically advantaged females with common mental disorders, who made moderate use of emergency departments but consulted general practitioners. Class 4 comprised older individuals with multiple chronic physical illnesses co-occurring with mental disorders, who made moderate use of the emergency department, but mainly consulted general practitioners.

CONCLUSIONS

The study found heterogeneity in emergency department use for mental health reasons, as each of the four classes represented distinct needs, predisposing and enabling factors. As such, interventions should be tailored to different classes of patients who use emergency departments, based on their characteristics.

Perception of treatment need among adults with substance use disorders: Longitudinal data from a representative sample of adults in the United States

BACKGROUND

Most individuals with substance use disorders (SUDs) do not seek treatment. Lack of perceived treatment need (PTN) is one contributing factor, but little is known about PTN over time. We estimated whether PTN changed over three years among those with SUDs in the United States and identified select variables, including sociodemographics and symptom burden, that predict malleability vs. stability of PTN.

METHODS

Data were from Waves 1 (collected 2001-2002) and 2 (collected 2004-2005) of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC); 1695 adults who met DSM criteria for alcohol or non-alcohol SUD at Wave 1 and maintained ≥1 diagnostic symptom at Wave 2 were included.

RESULTS

Most individuals with SUDs (77.2%) did not perceive a need for treatment at Wave 1 baseline. Only about 1 in 8 individuals not perceiving a need for treatment in Wave 1 came to perceive a need in Wave 2 (adjusted odds ratio = 0.18, 99% confidence interval = 0.11-0.29). In contrast, about half the individuals who perceived a need for treatment in Wave 1 no longer did so in Wave 2, despite maintaining ≥1 SUD symptom. Married respondents, and respondents with more SUD symptoms, were more likely to transition from low- to high-PTN status three years later. Respondents with incomes >$35,000 were less likely to transition to high-PTN status three years later.

CONCLUSIONS

PTN was more likely to decline than increase over time. Low PTN appears to be stable among adults with SUDs in the United States, presenting a potentially enduring barrier to treatment-seeking.

Cross-national patterns of substance use disorder treatment and associations with mental disorder comorbidity in the WHO World Mental Health Surveys

AIMS

To examine cross-national patterns of 12-month substance use disorder (SUD) treatment and minimally adequate treatment (MAT), and associations with mental disorder comorbidity.

DESIGN

Cross-sectional, representative household surveys.

SETTING

Twenty-seven surveys from 25 countries of the WHO World Mental Health Survey Initiative.

PARTICIPANTS

A total of 2446 people with past-year DSM-IV SUD diagnoses (alcohol or illicit drug abuse and dependence).

MEASUREMENTS

Outcomes were SUD treatment, defined as having either received professional treatment or attended a self-help group for substance-related problems in the past 12 months, and MAT, defined as having either four or more SUD treatment visits to a health-care professional, six or more visits to a non-health-care professional or being in ongoing treatment at the time of interview. Covariates were mental disorder comorbidity and several socio-economic characteristics. Pooled estimates reflect country sample sizes rather than population sizes.

FINDINGS

Of respondents with past-year SUD, 11.0% [standard error (SE) = 0.8] received past 12-month SUD treatment. SUD treatment was more common among people with comorbid mental disorders than with pure SUDs (18.1%, SE = 1.6 versus 6.8%, SE = 0.7), as was MAT (84.0%, SE = 2.5 versus 68.3%, SE = 3.8) and treatment by health-care professionals (88.9%, SE = 1.9 versus 78.8%, SE = 3.0) among treated SUD cases. Adjusting for socio-economic characteristics, mental disorder comorbidity doubled the odds of SUD treatment [odds ratio (OR) = 2.34; 95% confidence interval (CI) = 1.71-3.20], MAT among SUD cases (OR = 2.75; 95% CI = 1.90-3.97) and MAT among treated cases (OR = 2.48; 95% CI = 1.23-5.02). Patterns were similar within country income groups, although the proportions receiving SUD treatment and MAT were higher in high- than low-/middle-income countries.

CONCLUSIONS

Few people with past-year substance use disorders receive adequate 12-month substance use disorder treatment, even when comorbid with a mental disorder. This is largely due to the low proportion of people receiving any substance use disorder treatment, as the proportion of patients whose treatment is at least minimally adequate is high.

Behavioral health treatment utilization among individuals with co-occurring opioid use disorder and mental illness: Evidence from a national survey

BACKGROUND

Past research shows that among individuals with substance use disorders, the presence of a co-occurring mental illness can influence the initiation, course, and success of behavioral health treatment, but little research has examined people with opioid use disorder (OUD) specifically.

METHODS

Using the 2008-2014 National Survey on Drug Use and Health, this study examines the utilization of substance use disorder and mental health treatment among individuals with OUD and different degrees of mental illness severity. The study also examined types of treatment, perceived unmet need for treatment, and barriers to care.

RESULTS

47% of individuals with OUD and co-occurring mild/moderate mental illness did not receive any behavioral health treatment, and 21% of those with co-occurring serious mental illnesses did not receive any behavioral health treatment. Among those with OUD and co-occurring mild/moderate mental illness, 16% reported receiving both substance use disorder and mental health treatment; among those with co-occurring serious mental illness the rate was 32%. The most common form of treatment was prescription medication for mental health, and this was true regardless of whether or not the individual had any mental illness. More than 50% of the study population reported financial difficulties as a barrier to treatment.

CONCLUSION

A high proportion of individuals with OUD and co-occurring mental illness are not receiving needed care. However, nearly one in five of those with OUD but no diagnosed mental illness is receiving prescription medication for mental illness. These findings suggest that there is a need to better facilitate access to and coordinate behavioral health care across settings for individuals with OUD.

Resource Intensity for Children and Youth: The Development of an Algorithm to Identify High Service Users in Children's Mental Health

Children’s mental health care plays a vital role in many social, health care, and education systems, but there is evidence that appropriate targeting strategies are needed to allocate limited mental health care resources effectively. The aim of this study was to develop and validate a methodology for identifying children who require access to more intense facility-based or community resources. Ontario data based on the interRAI Child and Youth Mental Health instruments were analysed to identify predictors of service complexity in children’s mental health. The Resource Intensity for Children and Youth (RIChY) algorithm was a good predictor of service complexity in the derivation sample. The algorithm was validated with additional data from 61 agencies. The RIChY algorithm provides a psychometrically sound decision-support tool that may be used to inform the choices related to allocation of children’s mental health resources and prioritisation of clients needing community- and facility-based resources.

Mental Health Effects in Primary Care Patients 18 Months After a Major Wildfire in Fort McMurray: Risk Increased by Social Demographic Issues, Clinical Antecedents, and Degree of Fire Exposure

Objectives: To assess prevalence of likely posttraumatic stress disorder (PTSD), major depressive disorder (MDD), and generalized anxiety disorder (GAD) in patients attending the only out-of-hours primary care clinic in Fort McMurray some 18 months following a major fire. Methods: A quantitative cross-sectional survey was used to collect data through self-administered paper-based questionnaires to determine likely PTSD, MDD, and GAD using the PTSD Checklists for Diagnostic and Statistical Manual (DSM) 5, Patient Health Questionnaire (PHQ) 9, and GAD-7, respectively, from residents of Fort McMurray who were impacted by the wildfires. This was carried out eighteen (18) months after a major wildfire, which required the rapid evacuation of the entire city population (approximately 90,000 individuals). Results: We achieved a response rate of 48% and results from the 290 respondents showed the 1 month prevalence rate for likely PTSD was 13.6%, likely MDD was 24.8%, and likely GAD was 18.0%. Compared to self-reported prevalence rates before the wildfire (0%, 15.2%, and 14.5% respectively), these were increased for all diagnoses. After controlling for other factors in a logistic regression model, there were statistically significant associations between individuals who had likely PTSD, MDD, and GAD diagnoses and multiple socio-demographic, clinical, and exposure-related variables as follows: PTSD: History of anxiety disorder and received counselling had odds ratios (ORs) of 5.80 and 7.14, respectively. MDD: Age, witnessed the burning of homes, history of depressive disorder, and receiving low level support from friends and family had ORs of 2.08, 2.29, 4.63, and 2.5, respectively. GAD: Fearful for their lives or the lives of friends/family, history of depressive disorder, and history of anxiety disorder had ORs of 3.52, 3.04, and 2.68, respectively. There were also associations between individuals with a likely psychiatric diagnosis and those who also had likely alcohol or drug abuse/dependence. Conclusion: Our study suggests there are high prevalence rates for mental health and addiction conditions in patients attending the out-of-hours clinic 18 months after the wildfires, with significant associations between multiple variables and likely PTSD, MDD, and GAD. Further studies are needed to explore the impact of population-based mental health interventions on the long-term mental health effects of the wildfires.

Models of Concurrent Disorder Service: Policy, Coordination, and Access to Care

Background: Societal capacity to address the service needs of persons with concurrent mental health and substance-use disorders has historically been challenging given a traditionally siloed approach to mental health and substance-use care. As different approaches to care for persons with concurrent disorders emerge, a limited understanding of current models prevails. The goal of this paper is to explore these challenges along with promising models of coordinated care across Canadian provinces. Materials and methods: A scoping review of policies, service coordination and access issues was undertaken involving a review of the formal and gray literature from 2000 to 2018. The scoping review was triangulated by an analysis of provincial auditor general reports. Results: Models of concurrent disorders service were found to have evolved unevenly. Challenges related to the implementation of models of collaborative care and local networks that foster service coordination and policy accountability were found to inhibit integrated care. Conclusion: Emergent models of coordinated care were found to include collaborative care, regional networks with centralized access to care, clinical information-sharing, cross-training, improved scope of care to include psychologists and alignment of physician incentives with patient needs to better support patient care.

Predictors of mental health service use among individuals with high psychological distress and mental disorders

This study identified predictors of mental health service use over 12 months among 746 individuals with mental disorders and high psychological distress from a catchment area in southwest Montreal, Quebec (Canada). Data collected in 2011 and 2014 were analyzed using Andersen's Behavioral Model of Health Services Use. A hierarchical logistic regression identified predictors of mental health service use. In all, 29% of participants reported using mental health services in the previous 12 months. Three key enabling variables predicted mental health service use: having a family doctor, previous experience with mental health services, and employment. Self-perception of mental health, stressful events, and unmet needs marginally (Needs factors: non-clinical variables) were also associated with the outcome variable. Mental health service utilization depends primarily on organization of the health system, and patient perceptions of its condition (non-clinical needs). Mental health policy should focus on increasing the availability of services and professionals, especially family doctors. Other measures for encouraging service use and overall population wellbeing include raising public awareness around the signs and symptoms of mental illness as a way to promote more rapid response to patient needs, and protecting workplace mental health by reducing stress and stigma toward individuals affected by mental distress.

Cross-sectoral integration in youth-focused health and social services in Canada: a social network analysis

Background

Youth with concurrent substance use and mental health concerns have diverse psychosocial needs and may present to a multitude of clinical and social service sectors. By integrating service sectors at a system level, the diversity of needs of youth with concurrent disorders can be addressed in a more holistic way. The objective of the present study was to quantify the level of cross-sectoral integration in youth-focused services in Canada.

Methods

Social network analysis (SNA) was used to examine the relationships between eight sectors: addictions, child welfare, education, physical health, housing, mental health, youth justice, and other social services. A total of 597 participants representing twelve networks of youth-serving agencies across Canada provided information on their cross-sectoral contacts and referrals.

Results

Overall, results suggested a moderate level of integration between sectors. The mental health and the addictions sectors demonstrated only moderate integration, while the addictions sector was strongly connected with the youth justice sector.

Conclusions

Despite evidence of moderate integration, increased integration is called for to better meet the needs of youth with concurrent mental health and substance use concerns across youth-serving sectors. Ongoing efforts to enhance the integration between youth-serving sectors should be a primary focus in organizing networks serving youth with concurrent mental health and substance use needs.

Substance use and internalizing symptoms among high school students and access to health care services: results from a population-based study

OBJECTIVES

To examine co-occurring mental health problems among a population-based sample of high school students in Ontario, Canada, to understand their prevalence, associated risk factors, and relationship with mental health service access and utilization.

METHODS

The data were derived from the 2013 Ontario Student Drug Use and Health Survey, a biennial survey of students attending publicly funded Ontario schools, from a subsample of students who completed both the internalizing and substance use portions of the survey (n = 2945). Rates of co-occurring problems were calculated for the previous 12 months. Service use for students with co-occurring problems was also calculated for the past 12 months. Odds ratios were estimated using binary logistic regression models correcting for the survey design.

RESULTS

In an adjusted model, youth with internalizing symptoms were 2.40 times more likely and youth with substance use problems were 2.24 times more likely to have accessed mental health services during the past 12 months than youth without these problems. Youth with co-occurring internalizing and substance use problems were 6.74 times more likely (95% CI 4.66-9.76, p < 0.001) to have accessed mental health services during the past year compared with youth without co-occurring problems, but only 52.8% of youth with co-occurring problems (95% CI 45.6-59.9%) used mental health services.

CONCLUSIONS

The findings suggest that just over half of Ontario students in grades 9 through 12 who have co-occurring internalizing and substance use problems are utilizing mental health services. Further research should examine the factors related to service use in this population in order to better inform policy and program development.

Temporal Trends in Mental Health Service Utilization across Outpatient and Acute Care Sectors: A Population-Based Study from 2006 to 2014

OBJECTIVE

Although evidence suggests that treatment seeking for mental illness has increased over time, little is known about how the health system is meeting the increasing demand for services. We examined trends in physician-based mental health service use across multiple sectors.

METHOD

In this population-based study, we used linked health-administrative databases to measure annual rates of mental health-related outpatient physician visits to family physicians and psychiatrists, emergency department visits, and hospitalizations in adults aged 16+ from 2006 to 2014. We examined absolute and relative changes in visit rates, number of patients, and frequency of visits per patient, and assessed temporal trends using linear regressions.

RESULTS

Among approximately 11 million Ontario adults, age- and sex-standardized rates of mental health-related outpatient physician visits declined from 604.8 to 565.5 per 1000 population over the study period ( P_trend = 0.04). Over time, the rate of visits to family physicians/general practitioners remained stable ( P_trend = 0.12); the number of individuals served decreased, but the number of visits per patient increased. The rate of visits to psychiatrists declined ( P_trend < 0.001); the number of individuals served increased, but the number of visits per patient decreased. Concurrently, visit rates to emergency departments and hospitals increased (16.1 to 19.7, P_trend < 0.001 and 5.6 to 6.0, P_trend = 0.01, per 1000 population, respectively). Increases in acute care service use were greatest for anxiety and addictions.

CONCLUSIONS

The increasing acute care service use coupled with the reduction in outpatient visits suggest, overall, an increase in demand for mental health care that is not being met in ambulatory care settings.

Major depressive disorder and access to health services among people who use illicit drugs in Vancouver, Canada

BACKGROUND

People who use illicit drugs (PWUD) are commonly diagnosed with major depressive disorder (MDD). However, little is known about whether PWUD living with MDD experience additional barriers to accessing health services compared to those without MDD. We sought to identify whether MDD symptoms were associated with perceived barriers to accessing health services among people who use illicit drugs (PWUD) in Vancouver, Canada.

METHODS

Data were collected through prospective cohorts of PWUD in Vancouver, Canada between 2005 and 2016. Using multiple logistic regression, we examined the relationship between MDD symptoms, defined as a Centre for Epidemiologic Studies Depression (CES-D) scale total score of ≥16, and barriers to access health services. We also used descriptive statistics to examine common barriers among participants who reported any barriers.

RESULTS

Among a total of 1529 PWUD, including 521 (34.1%) females, 415 (27.1%) reported barriers to accessing health services, and 956 (62.5%) reported MDD symptoms at baseline. In multiple logistic regression analyses, after adjusting for a range of potential confounders, MDD symptoms (adjusted odds ratio [AOR] = 1.40; 95% confidence interval [CI]: 1.03-1.92) were positively and significantly associated with barriers to accessing health services. Among those who reported MDD symptoms and barriers to access, commonly reported barriers included: long wait lists/times (38.1%); and treated poorly by health care professionals (30.0%).

CONCLUSION

These findings show that the likelihood of experiencing barriers to accessing health services was higher among PWUD with MDD symptoms compared to their counterparts. Policies and interventions tailored to address these barriers are urgently needed for this subpopulation of PWUD.

Service Use and Unmet Needs for Substance Use and Mental Disorders in Canada

OBJECTIVE

To investigate patterns and predictors of help seeking and met/unmet needs for mental health care in a national population health survey.

METHOD

Participants were respondents to the 2012 Canadian Community Health Survey on Mental Health (CCHS-MH; n = 25,133). We used regression to identify the diagnostic and sociodemographic predictors of the use of informal supports, primary care, and specialist care, as well as perceived unmet needs.

RESULTS

Eleven percent of Canadians reported using professionally led services for mental health or substance use in 2012, while another 9% received informal supports. Two-thirds of people with substance use disorders did not receive any care, and among those who did, informal supports were most common. Seventy-four percent of people with mood/anxiety disorders and 88% of those with co-occurring disorders did access services, most commonly specialist mental health care. Men, older people, members of ethnocultural minorities, those not born in Canada, those with lower education, and those with higher incomes were less likely to receive care. Unmet needs were higher among people with substance use disorders.

CONCLUSIONS

Gaps in services continue to exist for some potentially vulnerable population subgroups. Policy and practice solutions are needed to address these unmet needs. In particular, the convergence of research pointing to gaps in the availability and accessibility of high-quality services for substance use in Canada demands attention.

The association of psychiatric comorbidity with treatment completion among clients admitted to substance use treatment programs in a U.S. national sample

BACKGROUND

Psychiatric disorders are highly comorbid with substance use disorders and play an important role in their course and recovery. However, the impact of comorbidity on treatment outcomes has not been examined in a U.S. national sample. This study explores the impact of psychiatric comorbidity on treatment completion among individuals admitted to publicly funded substance use treatment facilities across the United States.

METHODS

Using data on first-time treatment episodes in the U.S. from the Treatment Episode Dataset-Discharges (TEDS-D) for the years 2009-2011, logistic regression was used to assess the association between psychiatric comorbidity and treatment non-completion, and Cox proportional hazards regression was used to assess the association between comorbidity and rate of attrition. Analyses were performed for all substances together and then stratified by primary substance of abuse (alcohol, cannabis, stimulants, or opioids).

RESULTS

Of 856,385 client treatment episodes included in our analysis, 28% had a psychiatric comorbidity and 38% did not complete treatment. After adjusting for socio-demographic and treatment characteristics, clients with psychiatric comorbidity had higher odds of not completing treatment relative to those without comorbidity [OR=1.28 (1.27-1.29)], and had an earlier time to attrition [HR=1.14 (1.13-1.15)]. Psychiatric comorbidity was most strongly associated with treatment non-completion and rate of attrition in those admitted primarily for alcohol [OR=1.37 (1.34-1.39); HR=1.19 (1.17-1.21), respectively].

CONCLUSIONS

Individuals with psychiatric comorbidities receiving treatment for substance use disorders face unique challenges that impact their ability to complete treatment. The findings call for further efforts to integrate treatment for psychiatric comorbidities in substance use treatment settings.

A Review of Effective Youth Engagement Strategies for Mental Health and Substance Use Interventions

The majority of adult mental health and substance use (MH&SU) conditions emerge in adolescence. Prevention, diagnosis, and treatment programs targeting this age group have a unique opportunity to significantly impact the well-being of the future generation of adults. At the same time, youth are reluctant to seek treatment and have high rates of dropout from interventions. An emphasis on youth engagement in prevention and treatment interventions for MH&SU results in better health outcomes for those youth. This literature review was undertaken to evaluate opportunities to improve youth engagement in MH&SU programs. The intent was to determine best practices in the field that combined community-level improvement in clinical outcomes with proven strategies in engagement enhancement to inform program development at a local level. The results discuss 40 studies, reviews, and program reports demonstrating effective youth engagement. These have been grouped into six themes based on the underlying engagement mechanism: youth participation in program development, parental relationships, technology, the health clinic, school, and social marketing. A broad range of tools are discussed that intervention developers can leverage to improve youth engagement in prevention or treatment programs.

Evaluating the Complex: Alternative Models and Measures for Evaluating Collaboration among Substance use Services with Mental Health, Primary Care and other Services and Sectors

Many planners and administrators now look to “collaboration” or “integration” as a solution, or at least a partial solution, to challenges related to access and delivery of substance use and mental health services and health services in general. Among the major constraints in identifying best practices in this area and recommending optimal evaluation strategies are the plethora of terms and concepts used in the literature to describe collaboration or integration as well as the many alternative approaches and outcome expectations. It is helpful, therefore, to follow concrete steps to plan the evaluation, including the engagement of multiple stakeholders in the planning process and subsequent execution of the evaluation. The concrete evaluation strategies employed can follow a traditional, often linear model, of impact and are often categorized under the common typologies of process, outcome or economic evaluations. Each approach examines different domains of interest and can be at the individual/service level or at the level of the overall treatment system. Other less traditional evaluation models and methods based on systems theory, complex adaptive systems and developmental evaluation have much to offer the evaluation of interventions aimed at improving the collaboration and integration of substance use services with other health and social services and sectors. Realist evaluation is a particularly helpful approach that integrates many of the traditional approaches with these other models and methods.

How Much Do Mental Health and Substance Use/Addiction Affect Use of General Medical Services? Extent of Use, Reason for Use, and Associated Costs

OBJECTIVE

To measure service use and costs associated with health care for patients with mental health (MH) and substance use/addiction (SA) problems.

METHODS

A 5-year cross-sectional study (2007-2012) of administrative health care data was conducted (average annual sample size = 123,235 adults aged >18 years who had a valid Ontario health care number and used at least 1 service during the year; 55% female). We assessed average annual use of primary care, emergency departments and hospitals, and overall health care costs for patients identified as having MH only, SA only, co-occurring MH and SA problems (MH+SA), and no MH and/or SA (MH/SA) problems. Total visits/admissions and total non-MH/SA visits (i.e., excluding MH/SA visits) were regressed separately on MH, SA, and MH+SA cases compared to non-MH/SA cases using the 2011-2012 sample ( N = 123,331), controlling for age and sex.

RESULTS

Compared to non-MH/SA patients, MH/SA patients were significantly ( P < 0.001) more likely to visit primary care physicians (1.82 times as many visits for MH-only patients, 4.24 for SA, and 5.59 for MH+SA), use emergency departments (odds, 1.53 [MH], 3.79 [SA], 5.94 [MH+SA]), and be hospitalized (odds, 1.59 [MH], 4.10 [SA], 7.82 [MH+SA]). MH/SA patients were also significantly more likely than non-MH/SA patients to have non-MH/SA-related visits and accounted for 20% of the sample but over 30% of health care costs.

CONCLUSIONS

MH and SA are core issues for all health care settings. MH/SA patients use more services overall and for non-MH/SA issues, with especially high use and costs for MH+SA patients.

Typology of individuals with substance dependence based on a Montreal longitudinal catchment area study

This study sought to develop a typology of individuals with substance dependence (ISD) based on a longitudinal survey (n = 2,434) and 121 ISD. The latter were divided into three groups: newly abstinent individuals, chronic dependents and acute dependents. Individuals' typology was developed by cluster analysis. Newly abstinent individuals had fewer emotional problems and mental disorders in the previous 12 months. Four classes of ISD were identified, labelled respectively "chronic multi-substance consumption and mental disorders comorbidities," "multi-substance consumption," "alcohol and marijuana consumption" and "alcohol consumption only." Strategies adapted to each of these profiles could be promoted for more effective treatment.

Inability to access health and social services associated with mental health among people who inject drugs in a Canadian setting

BACKGROUND

People who inject drugs (PWID) face barriers to healthcare due to reasons including comorbidity. We evaluated access to health and social services by three of the most prevalent comorbid conditions among PWID: HIV, hepatitis C (HCV), and mental health, in an urban setting in Canada.

METHODS

Data were derived from prospective cohorts of community-recruited PWID between 2005 and 2015. HIV and HCV serostatuses were based on antibody tests, while mental health conditions and inability to access health and social services (barriers to access) were determined by participants' self-report. We employed generalized linear mixed models controlling for confounders to examine associations between health conditions and barriers to access.

RESULTS

Among 2494 participants, 1632 (65.4%) reported barriers to access at least once over a median of seven (IQR: 3, 12) semi-annual assessments. Mental health conditions were independently associated with increased odds of reporting barriers (adjusted Odds Ratio (aOR): 1.45, 95% Confidence Interval (CI): 1.32, 1.58), while HIV was not (aOR: 0.96, 95% CI: 0.85, 1.08), and HCV was associated with decreased odds (aOR: 0.80, 95% CI: 0.69, 0.93). The associations between mental health conditions and barriers to access were consistent among PWID without HIV/HCV (aOR: 1.35, 95% CI: 1.10, 1.65), with HCV mono-infection (aOR: 1.55, 95% CI: 1.37, 1.75), and HCV/HIV co-infection (aOR: 1.36, 95% CI: 1.15, 1.60).

CONCLUSIONS

Targeted strategies to seek and treat mental health conditions in settings that serve PWID, and assist PWID with mental health conditions in navigating healthcare system may improve the publicly-funded health and social services.

Factors associated with high use of general practitioner and psychiatrist services among patients attending an addiction rehabilitation center

BACKGROUND

This study aimed to 1) identify the characteristics of individuals with substance use disorders (SUDs) who make high use of services provided by general practitioners (GP) and psychiatrists while receiving services concurrently from an addiction rehabilitation center (ARC), and 2) to compare high service users to moderate and low service users.

METHODS

Data were compiled for 4,407 individuals with SUDs who were receiving services from an ARC in 2004. The data came from the merging of four databases: the ARC data registry (January 1(st), 2004-December 31, 2004), the Quebec Health Insurance Board database (March 31, 2003-April 1st, 2005), the Quebec provincial database for hospitalizations (March 31, 2003-April 1st, 2005), and the Quebec National Institute of Public Health database (2004). Independent variables were grouped according to the Andersen Behavioral Model of Health Services Use: predisposing, enabling and need factors. Generalized estimating equations analyses were performed to assess the influence of individual and neighborhood-level characteristics on high use of services outside the ARC provided by GPs and psychiatrists. Benjamini-Hochberg's procedure was applied to correct for multiple comparisons.

RESULTS

About 97 % of individuals attending the ARC consulted a GP or a psychiatrist during the two-year study period, for a mean of 1.5 consultations per month. Findings revealed that 5 % of the sample made 26 % of all consultations over the two years, and they were defined as high users. No single predisposing factor was associated with high use. One enabling factor significantly increased the risk of being a high user of services from general practitioners and psychiatrists: receiving services at the ARC for three years prior to 2004. Four needs factors, all related to mental health diagnoses (schizophrenia, mood disorder, anxiety disorder, personality disorder), predicted high use of general practitioner and psychiatrist services.

CONCLUSIONS

This study found that nearly all individuals with SUDs receiving services from an ARC were users of health services from GPs and psychiatrists outside the ARC. High users most probably accessed them in inpatient settings. No previous study has compared high service users with low and moderate users among individuals with SUDs. Considering that ARCs are treating individuals with complex needs, some of whom make high use of medical professionals, both ARCs and their clients could benefit from increased collaboration and integration between the addictions and mental healthcare sectors.

Implementing Key Strategies for Successful Network Integration in the Quebec Substance-Use Disorders Programme

BACKGROUND

Fragmentation and lack of coordination often occur among organisations offering treatment for individuals with substance-use disorders. Better integration from a system perspective within a network of organisations offering substance-use disorder services can be developed using various integration strategies at the administrative and clinical levels. This study aims to identify integration strategies implemented in Quebec substance-use disorder networks and to assess their strengths and limitations.

METHODS

A total of 105 stakeholders representing two regions and four local substance-use disorder networks participated in focus groups or individual interviews. Thematic qualitative and descriptive quantitative analyses were conducted.

RESULTS

Six types of service integration strategies have been implemented to varying degrees in substance-use disorder networks. They are: 1) coordination activities-governance, 2) primary-care consolidation models, 3) information and monitoring management tools, 4) service coordination strategies, 5) clinical evaluation tools and 6) training activities.

CONCLUSION

Important investments have been made in Quebec for the training and assessment of individuals with substance-use disorders, particularly in terms of support for emergency room liaison teams and the introduction of standardised clinical evaluation tools. However, the development of integration strategies was insufficient to ensure the implementation of successful networks. Planning, consolidation of primary care for substance-use disorders and systematic implementation of various clinical and administrative integration strategies are needed in order to ensure a better continuum of care for individuals with substance-use disorders.

Service user and family member perspectives on services for mental health, substance use/addiction, and violence: a qualitative study of their goals, experiences and recommendations

BACKGROUND

Mental health and substance use disorders (MSD) are significant public health concerns that often co-occur with violence. To improve services that address MSD and violence [MSD(V)], it is critical to understand the perspectives of those most affected, people who have sought help for MSD(V) (i.e., "service users"), especially those with co-occurring issues, as well as their family members.

METHODS

We conducted structured interviews with 73 service users and 41 family members of service users in two Ontario communities (one urban, one rural) regarding their goals related to help-seeking, positive and negative experiences, and recommendations for improving systems of care.

RESULTS

Overall, participants expressed a need for services that: (1) are respectful, nonjudgmental, and supportive, help service users to feel more 'normal' and include education to reduce stigma; (2) are accessible, varied and publicly funded, thereby meeting individual needs and addressing equity concerns at a systems level; and (3) are coordinated, holistic and inclusive of family members who often support service users.

CONCLUSIONS

The findings provide a rich understanding of how service users and their families perceive services for MSD(V) issues and identify key ways to better meet their needs.

Help Received for Perceived Needs Related to Mental Health in a Montreal (Canada) Epidemiological Catchment Area

This study sought to identify variables associated with help received in terms of information, medication, counselling and total help received (including other needs) among 571 individuals needing health care services for mental health problems. Study participants were randomly selected from an epidemiological survey. Data on help received were collected using the Canadian version of the Perceived Need for Care Questionnaire (PNCQ), and were analyzed using a multinomial logistic regression model. Most help received was in the form of counselling, followed by medication and information. Compared with individuals who received no help, those who reported receiving help for all their needs were more likely to have psychological distress, to be non-verbally aggressive, to consult more healthcare professionals, to be men and to be somewhat older. Compared with individuals who received no help, those who received partial help were more likely to be not addicted to drugs or alcohol, to consult more healthcare professionals, and to be older. Healthcare services should prioritize strategies (e.g., early detection, outreach, public education on mental and addiction disorders) that address barriers to help seeking among youth, as well as individuals addicted to drugs and alcohol or those presenting with aggressive behavior.

Profiles Associated Respectively with Substance Dependence Only, Mental Disorders Only and Co-occurring Disorders

This study sought to identify profiles associated with substance dependence only, mental disorders only and co-occurring disorder respectively, using a broad range of socio-demographic, socio-economic, health beliefs, clinical and health services utilization variables concurrently. Based on a broad analytic framework, 423 participants diagnosed with substance dependence only, mental disorders only or co-occurring disorders within a 12-months period were studied. The study used comparison analysis, and a multinomial logistic regression model. Participants with dependence only and mental disorders only were in contrast in terms of gender, age, marital status, self-perception of physical health, perception of the physical conditions of their neighbourhood, impulsiveness, psychological distress and visit with a family physician in previous 12-months, while those with co-occurring disorders were in an intermediary position between the other two groups. Public authorities should especially promote strategies that could increase the capacity of family physicians to take care of individuals with substance dependence only.

Predictors of frequent recourse to health professionals by people with severe mental disorders

OBJECTIVE

Based on Andersen's behavioural model, our study sought to determine predictors and blocks of factors that could explain why people with severe mental disorders (SMDs) more often seek the services of health professionals.

METHODS

This longitudinal study involved 292 users with SMDs located in Le Sud-Ouest, the southwest borough of Montreal. Data were collected from participants' medical records and through 7 questionnaires. Using Andersen's Behavioral Model of Health Services Use, independent variables were divided into 3 classes-predisposing factors, enabling factors, and need factors-and were introduced in this order in a hierarchical logistic model.

RESULTS

Among 292 users, 110 (37.7%) were frequent users who consulted about one health professional every 3 days. Participants who were more likely to call on health professionals were single and older, depended on welfare as their main source of income, lived in supervised housing, suffered from schizophrenia, schizophrenia spectrum disorders, and adjustment disorders, and, marginally, exhibited multiple mental disorders.

CONCLUSION

Mental health services could promote strategies to overcome the reluctance of younger people to seek professional services. Professionals should pay close attention to subsidiary conditions, such as adjustment disorders, from which people with SMDs may suffer. Interventions to improve the socioeconomic condition of unemployed people with SMDs may help to reduce health care service use among that clientele. Programs such as supported employment should be tailored and enhanced for people receiving welfare to decrease stigmatization and improve job market integration.

Predictors of healthcare service utilization for mental health reasons

This study was designed to identify: (1) predictors of 12-month healthcare service utilization for mental health reasons, framed by the Andersen model, among a population cohort in an epidemiological catchment area; and (2) correlates associated with healthcare service utilization for mental health reasons among individuals with and without mental disorders respectively. Analyses comprised univariate, bivariate, and multiple regression analyses. Being male, having poor quality of life, possessing better self-perception of physical health, and suffering from major depressive episodes, panic disorder, social phobia, and emotional problems predicted healthcare service utilization for mental health reasons. Among individuals with mental disorders, needs factors (psychological distress, impulsiveness, emotional problems, victim of violence, and aggressive behavior) and visits to healthcare professionals were associated with healthcare service utilization for mental health reasons. Among individuals without mental disorders, healthcare service utilization for mental health reasons is strongly associated with enabling factors such as social support, income, environmental variables, and self-perception of the neighborhood. Interventions facilitating social cohesion and social solidarity in neighborhood settings may reduce the need to seek help among individuals without mental disorders. Furthermore, in their capacity as frontline professionals, general practitioners should be more sensitive in preventing, detecting, and treating mental disorders in routine primary care.

Predictors of alcohol and drug dependence

OBJECTIVE

Our study sought to identify sociodemographic, clinical, life perception, and service use characteristics that distinguish new cases of people dependent on substances from the general population; and to determine predictors of substance dependence over a 2-year period. Variables that differentiate people dependent on substances according to sex and age were also assessed.

METHODS

Among 2434 people who took part in an epidemiologic catchment area health survey at baseline, 2.2% were identified with substance dependence at the second measurement time only. Using a comprehensive framework, various aspects were considered as predictors for multivariate statistics.

RESULTS

Participants with substance dependence at time 2 only showed worse clinical conditions, life events, life and health perception, and neighbourhood characteristics than other participants, but only 2.5% used health care services. Male sex, younger age, stigmatization, and impulsiveness were predictors of substance dependence. Regarding sex, females with dependence were only more likely to suffer from social phobia than males. In terms of age categories, participants over 50 with substance dependence were more likely to have a lower household income and less social support than younger people.

CONCLUSION

Stigmatization was the strongest predictor of substance dependence. Our study also confirmed that males and younger people were more likely to have substance dependence. Anti-stigmatization, prevention, and outreach programs are needed to overcome the reluctance of this clientele to use health care services. Health professionals should also pay more attention to life and health perception and neighbourhood characteristics of newly identified drug users.

Service use and barriers to mental health care among adults with major depression and comorbid substance dependence

OBJECTIVE

The study explored mental health service use patterns and barriers to care among individuals with comorbid mental and substance use disorders.

METHODS

Using data from the National Survey on Drug Use and Health (2005-2010) for 18,972 adults with past-year major depressive episodes, the study compared mental health service use and perceived barriers to care among participants with and without co-occurring alcohol dependence, nonalcohol drug dependence, and both alcohol and drug dependence.

RESULTS

Compared with participants without comorbid substance dependence, participants with alcohol dependence or both alcohol and nonalcohol drug dependence used more mental health services of all types, and participants with only comorbid alcohol dependence used more medication treatments. Participants with comorbid substance dependence were significantly more likely than those without comorbid substance dependence to report unmet mental health treatment need. However, barriers to mental health care were remarkably similar across groups, with financial barriers being the most common in all groups.

CONCLUSIONS

Participants with major depression comorbid with substance dependence used more mental health services but also perceived more unmet need for such care than individuals without such comorbidity. However, barriers to mental health care were similar across groups with and without comorbidity. Policies aimed at expanding insurance coverage and mental health parity would likely benefit individuals with major depression and substance dependence comorbidity even more than those without such comorbidity.

Comparing barriers to mental health treatment and substance use disorder treatment among individuals with comorbid major depression and substance use disorders

Barriers to both mental health and substance use disorder treatments have rarely been examined among individuals with comorbid mental health and substance use disorders. In a sample of 393 adults with 12-month major depressive episodes and substance use disorders, we compared perceived barriers to these two types of treatments. Data were drawn from the 2005-2011 U.S. National Surveys on Drug Use and Health. Overall, the same individuals experienced different barriers to mental health treatment versus substance use disorder treatment. Concerns about negative views of the community, effects on job, and inconvenience of services were more commonly reported as reasons for not receiving substance use disorder treatment. Not affording the cost of care was the most common barrier to both types of treatments, but more commonly reported as a barrier to mental health treatment. Improved financial access through the Affordable Care Act and parity legislation and integration of mental health and substance use disorder services may help to reduce treatment barriers among individuals with comorbid mental health and substance disorders.

Tiered Frameworks for Planning Substance Use Service Delivery Systems: Origins and Key Principles

It is well known that only a relatively small proportion of people in the community who experience substance use problems seek assistance from the specialized sector of services that have been commissioned to provide treatment and support for these problems. Going back to seminal reports from the early 1990s there has been a call for a systems approach to “broaden the base of treatment” in order to achieve wider coverage and yield positive outcomes at a population level. In some jurisdictions conceptual models referred to as “tiered models” have been advanced to support planning, system design and performance monitoring. This paper traces the evolution of such tiered models for substance use services and describes a recent model advanced in Ontario Canada for design of an integrated system of mental health, substance use and problem gambling services and supports. The paper concludes by highlighting key features and principles of the tiered approach that are critical for its actual operationalization. Some challenges operationalizing such a comprehensive system design framework are also noted.

Treatment delay and excessive substance use in bipolar disorder

The aim of the present study was to investigate the relationship between treatment delay and excessive substance use. A total of 151 bipolar disorder (BD) I and II patients were consecutively recruited from in- and outpatient psychiatric units, and categorized as primary or secondary BD (without or with antecedent excessive substance use). Predictors of treatment delay among all patients, and predictors of subsequent excessive substance use among primary BD patients, were investigated with logistic regression analyses. The median treatment delay was 2.0 years (IQR 14.0). The risk of long treatment delays was increased in patients with BD II disorder, no lifetime psychosis, a higher age at first contact with specialized psychiatric services, primary BD, and excessive substance use. In primary BD, the risk for developing excessive substance use was increased in males, in patients with shorter education and longer treatment delays. Patients with antecedent excessive substance use had reduced risk of long treatment delays. The risk of developing excessive substance use after BD onset increased with longer treatment delays.

Estimating the number of children exposed to parental psychiatric disorders through a national health survey

OBJECTIVE

Children whose parents have psychiatric disorders experience an increased risk of developing psychiatric disorders, and have higher rates of developmental problems and mortality. Assessing the size of this population is important for planning of preventive strategies which target these children.

METHODS

National survey data (CCHS 1.2) was used to estimate the number of children exposed to parental psychiatric disorders. Disorders were diagnosed using the World Psychiatric Health Composite International Diagnostic Interview (WMH-CIDI) (12 month prevalence). Data on the number of children below 12 years of age in the home, and the relationship of the respondents with the children, was used to estimate exposure. Parent-child relations were identified, as was single parenthood. Using a design-based analysis, the number of children exposed to parental psychiatric disorders was calculated.

RESULTS

Almost 570,000 children under 12 live in households where the survey respondent met criteria for one or more mood, anxiety or substance use disorders in the previous 12 months, corresponding to 12.1% of Canadian children under the age of 12. Almost 3/4 of these children have parents that report receiving no mental health care in the 12 months preceding the survey. For 17% of all Canadian children under age 12, the individual experiencing a psychiatric disorder is the only parent in the household.

CONCLUSION

The high number of children exposed causes major concern and has important implications. Although these children will not necessarily experience adversities, they possess an elevated risk of accidents, mortality, and of developing psychiatric disorders. We expect these estimates will promote further research and stimulate discussion at both health policy and planning tables.

Prevalence of co-occurring substance use and other mental disorders in the Canadian population

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.

Use of health care services by patients with co-occurring severe mental illness and substance use disorders

BACKGROUND

To better respond to the health care needs of people with co-occurring mental illness and substance use disorders, it is vital to understand their itinerary through the health care system.

AIM

To describe the characteristics of service utilization among patients with co-occurring disorders in a large urban area.

METHOD

We used a sample (n = 5467) constituted from administrative and clinical databases. Those identified as having substance use disorders and psychoses were followed over 12 months with respect to their utilization of medical services. A descriptive analysis of the data and a two-step cluster analysis were undertaken.

RESULTS

Our analyses revealed a relatively high utilization of emergency services, outpatient clinics, private practices and hospitalization among patients with co-occurring disorders of severe mental illness and substance use. The two-step cluster analysis produced four heterogeneous groups in terms of service utilization.

CONCLUSIONS

This study demonstrates the need to develop strategies for organizing health care and services that are adapted to various sites of service utilization and to diverse profiles of patients with co-occurring mental illness and substance use disorders.
