Service Use for Mental Health Reasons: Cross-Provincial Differences in Rates, Determinants, and Equity of Access

Helen-Maria Vasiliadis; Alain Lesage; Carol E. Adair; Richard Boyer

Objectives: In 2002, Canada undertook its first national survey on mental health and well-being, including detailed questioning on service use. Mental disorders may affect more than 1 person in 5, according to past regional and less comprehensive mental health surveys in Canada, and most do not seek help. Individual determinants play a role in health resource use for mental health (MH) reasons. This study aimed to provide prevalence rates of health care service use for MH reasons by province and according to service type and to examine determinants of MH service use in Canada and across provinces. Methods: We assessed the prevalence rate (95% confidence interval [CI]) of past-year health service use for MH reasons, and we assessed potential determinants cross-sectionally, using data collected from the Statistics Canada Canadian Community Health Survey: Mental Health and Well-Being (CCHS 1.2). We estimated models of resource use with logistic regression (using odds ratios and 95%CIs). Results: The prevalence of health service use for MH reasons in Canada was 9.5% (95%CI, 9.1% to 10.0%). The highest rates, on average, were observed in Nova Scotia (11.3%; 95%CI, 9.6% to 13.0%) and British Columbia (11.3%; 95%CI, 10.1% to 12.6%). The lowest rates were observed in Newfoundland and Labrador (6.7%; 95%CI, 5.3% to 8.0%) and Prince Edward Island (7.5%; 95%CI, 5.8% to 9.3%). In Canada, the general medical system was the most used for MH reasons (5.4%; 95%CI, 5.1% to 5.8%) and the voluntary network sector was the least used (1.9%; 95%CI, 1.7% to 2.1%). No difference was observed in the rate of service use between specialty MH (3.5%; 95%CI, 3.2% to 3.8%) and other professional providers (4.0%; 95%CI, 3.7% to 4.3%). In multivariate analyses, after adjusting for age and sex, the presence of a mental disorder was a consistent predictor of health service use for MH across the provinces. Conclusions: There is up to a twofold difference in the type of service used for MH reasons across provinces. The primary care general medical system is the most widely used service for MH. Need remains the strongest predictor of use, especially when a mental disorder is present. Barriers to access, such as income, were not identified in all provinces. Different sociodemographic variables played a role in service seeking within each province. This suggests different attitudes toward common mental disorders and toward care seeking among the provinces.

IMPORTANCE Scattered-site housing with Intensive Case Management (ICM) may be an appropriate and less-costly option for homeless adults with mental illness who do not require the treatment intensity of Assertive Community Treatment. OBJECTIVE To examine the effect of scattered-site housing with ICM services on housing stability and generic quality of life among homeless adults with mental illness and moderate support needs for mental health services. DESIGN, SETTING, AND PARTICIPANTS The At Home/Chez Soi project was an unblinded, randomized trial. From October 2009 to July 2011, participants (N = 1198) were recruited in 4 Canadian cities (Vancouver, Winnipeg, Toronto, and Montreal), randomized to the intervention group (n = 689) or usual care group (n = 509), and followed up for 24 months. INTERVENTIONS The intervention consisted of scattered-site housing (using rent supplements) and off-site ICM services. The usual care group had access to existing housing and support services in their communities. MAIN OUTCOMES AND MEASURES The primary outcome was the percentage of days stably housed during the 24-month period following randomization. The secondary outcome was generic quality of life, assessed by a EuroQoL 5 Dimensions (EQ-5D) health questionnaire. RESULTS During the 24 months after randomization, the adjusted percentage of days stably housed was higher among the intervention group than the usual care group, although adjusted mean differences varied across sites. [table: see text] The mean change in EQ-5D score from baseline to 24 months among the intervention group was not statistically different from the usual care group (60.5 [95%CI, 58.6 to 62.5] at baseline and 67.2 [95%CI, 65.2 to 69.1] at 24 months for the intervention group vs 62.1 [95% CI, 59.9 to 64.4] at baseline and 68.6 [95%CI, 66.3 to 71.0] at 24 months for the usual care group, difference in mean changes, 0.10 [95%CI, −2.92 to 3.13], P=.95). CONCLUSIONS AND RELEVANCE Among homeless adults with mental illness in 4 Canadian cities, scattered site housing with ICM services compared with usual access to existing housing and community services resulted in increased housing stability over 24 months, but did not improve generic quality of life.

Objective: To evaluate the usefulness of administrative data for the surveillance of mental illness in Canada using databases in the following 5 provinces: British Columbia, Ontario, Quebec, Nova Scotia, and Alberta. Method: We used a population-based record-linkage analysis with data from physician billings, hospital discharge abstracts, and community-based clinics. The following diagnostic codes from the International Classification of Diseases, Ninth Edition, were used to define cases: 290 to 319, inclusive. Results: The prevalence of treated psychiatric disorder was similar in Nova Scotia, British Columbia, Alberta, and Ontario at about 15%. The prevalence for Quebec was slightly lower at 12%. Findings from the provinces showed remarkable consistency across age and sex, despite variations in data coding. Women tended to show a higher prevalence overall of treated mental disorders than men. Prevalence increased steadily to middle age, declining in the 50s and 60s, and then increasing again after age 70 years. Conclusions: Provincial and territorial administrative data can provide a useful, reliable, and economical source of information for the surveillance of treated mental disorders. Such a surveillance system can provide longitudinal data at little cost to support health service provision and planning.

Objective: To examine the determinants that lead Canadian adults to consult family physicians, psychiatrists, psychologists, psychotherapists, and other health professionals for mental health reasons and to compare the determinants of service use across provider types. Method: Data from the Canadian Community Health Survey: Mental Health and Well-Being were used for people aged 18 years and older (n = 35 236). A multivariate logistic regression was used to model outpatient consultations with different providers as a function of predictive determinants. Result: Three types of variables were examined: need, enabling, and predisposing factors. Among need, the most common predictors of service use for mental health reasons were self-rated mental health, the presence of chronic conditions, depression and panic attacks, unmet mental health needs, psychological well-being, and the ability to handle daily demands. Among enabling factors, emotional and informational support and income were important predictors. Among predisposing factors, men were less likely to consult with a family physician and other resources but not with psychiatrists; and people with less education were less likely to consult psychologists and other health providers. Conclusion: Need factors were the most important predictors of both psychiatrist and combined family physician and psychiatrist consultation in the previous year. However, sex barriers remain and promotion campaigns in seeking mental health care should be aimed toward men. Further, education and income barriers exist in the use of specialty providers of psychotherapy and policies should thus focus on rendering these services more accessible to disadvantaged people.

Mental disorders and mental health care in Canada and Australia: comparative epidemiological findings

BackgroundCanada and Australia although geographically distant have similarities in human geography and history. Each has had a national mental health policy for some years, but Australia has driven policy implementation in this area harder than has Canada. Comparable epidemiological surveys from Australia in 1997 and Canada in 2002 allow us to explore relative rates of mental disorders and compare estimates of access to care from mental health services.MethodsWe compare findings from the Australian National Survey of Mental Health and Wellbeing (1997) with those from the Canadian Community Health Survey on Mental Health and Well Being, cycle 1.2 (2002).ResultsDifferences in prevalence rates and in service utilisation emerge between the two countries: Anxiety Disorders are estimated as almost 2% higher in Canada than in Australia while there is suggestion that Major Depressive Disorder, Alcohol Dependence and Drug Dependence may be more prevalent in Australia. More of the people with co-morbid disorders in Australia than in Canada make use of mental health services and a finding of marginal significance suggests that this may be true across all disorders.ConclusionsCausation cannot be determined from this study but possible explanations for differences in prevalence include changes in global economic, political and security contexts and concerns between 1997 and 2002 and the possible role of greater availability of alcohol in Australia. The findings also provide encouragement that strenuously implementing a national mental health policy may have been of benefit to people with mental health problems in Australia.

Les données de l’étude ESA ont été appariées aux données d’utilisation des services médicaux et pharmaceutiques de la Régie d’assurance maladie du Québec pour documenter la prescription potentiellement non appropriée de benzodiazépines chez les personnes âgées. Nos résultats indiquent que 32% des répondants ont pris une dose journalière moyenne de 6.1 mg de l’équivalent diazépam pour une durée moyenne de 205 jours par année. Nos résultats indiquent aussi que presque la moitié, 48% des utilisateurs de benzodiazépines, ont reçu au moins une prescription de benzodiazépine potentiellement non appropriée pendant les 12 mois qui précédaient l’étude. Près de 23% des consommateurs ont reçu au moins une prescription concomitante de Bzs et d’un autre médicament pouvant résulter en une interaction sérieuse. De plus, les personnes âgées de 75 ans et plus avaient plus de chances de recevoir une Bz pour une longue période de temps que les personnes âgées de 65–74 ans. Cette étude a montré que la durée d’utilisation des benzodiazépines augmentait avec le nombre de prescripteurs et avec le nombre de pharmacies consultées pendant l’année. Le nombre de pharmacies utilisées a aussi été associé avec la présence d’une ordonnance non appropriée de benzodiazépines pendant la même année. Nos résultats plaident en faveur d’un système de santé plus intégré, incluant une révision régulière des médicaments pris par les personnes âgées. ESA study data were paired with Quebec medical and pharmaceutical services records to document potentially inappropriate benzodiazepines (Bzs) prescriptions among community-dwelling adults aged 65 and older. Results indicate that 32 per cent of respondents took a mean daily dose of 6.1 mg of equivalent diazepam for, on average, 205 days per year. Almost half (48%) of Bzs users received a potentially inappropriate benzodiazepine prescription at least once during the year preceding the survey. About 23 per cent received at least one concomitant prescription of a Bz and another drug that could result in serious interaction. In addition, individuals aged 75 and older were more likely to receive Bzs for a longer period of time than those aged 65–74. Number of pharmacies used was associated with inappropriate Bzs prescriptions. Our results argue in favour of a more integrated health services system, including a regular review of older adults’ drug regimens.

Objective: There is increasing interest in the use of administrative data for surveillance and research in Australia. The purpose of the present study was to evaluate the usefulness of such data for the surveillance of mood and anxiety disorder using databases from the following Canadian provinces: British Columbia, Ontario, Quebec and Nova Scotia. Method: A population-based record-linkage analysis was done using data from physician billings and hospital discharge abstracts, and community-based clinics using a case definition of ICD-9 diagnoses of 296.0–296.9, 311.0, and 300.0–300.9. Results: The prevalence of treated mood and/or anxiety disorder was similar in Nova Scotia, British Columbia, and Ontario at approximately 10%. The prevalence for Quebec was slightly lower at 8%. Findings from the provinces showed consistency across age and sex despite variations in data coding. Women tended to show a higher prevalence overall of mood and anxiety disorder than men. There was considerably more variation, however, when treated anxiety (300.0–300.9) and mood disorders (296.0–296.9, 311.0) were considered separately. Prevalence increased steadily to middle age, declining in the 50s and 60s, and then increased after 70 years of age. Conclusions: Administrative data can provide a useful, reliable and economical source of information for the surveillance of treated mood and/or anxiety disorder. Due to the lack of specificity, however, in the diagnoses and data capture, it may be difficult to conduct surveillance of mood and anxiety disorders as separate entities. These findings may have implications for the surveillance of mood and anxiety disorders in Australia with the development of a national network for the extraction, linkage and analysis of administrative data.
