    Abstract:
    OBJECTIVE: Epidemiologic research has demonstrated that the majority of mental illness in the community is not treated. Primary care physicians and the specialty mental health sector each have an important role in the provision of mental health services. Our goal is to clarify the extent of undertreatment of selected mental illnesses in Ontario and to examine how treatment is divided between the primary care and specialty sectors. In particular, we are interested in both the relative numbers and the types--based on sociodemographic and severity indicators--of patients found in each sector, as well as in confirming the key role of primary care in the provision of mental health services. METHODS: Data were taken from the Mental Health Supplement to the Ontario Health Survey, a community survey of 9953 individuals. All subjects who met DSM-III-R criteria for a past year diagnosis of mood, anxiety, substance abuse, bulimic, or antisocial personality disorders were categorized by their use of mental health services in the preceding year--into nonusers, primary care only patients, specialty only patients, and both sector patients. The 3 groups utilizing services were then compared by demographic, clinical, and disability characteristics. RESULTS: Only 20.8% of subjects with a psychiatric diagnosis reported use of mental health services, but 82.9% of these same individuals used primary care physicians for general health problems. Among those who used mental health services, 38.2% used family physicians only for psychiatric treatment, compared with 35.8% who used only specialty mental health providers, and 26.0% who used both sectors. The 3 groups of users showed only modest differences on sociodemographic characteristics. Patients in the specialty only sector reported significantly higher rates of sexual and physical abuse. On specific disability measures, all 3 groups were similar. CONCLUSION: The vast majority of individuals with an untreated psychiatric disorder are using the primary care sector for general health treatment, allowing an opportunity for identification and intervention. Primary care physicians also treat the majority of those seeking mental health services, and individuals seen only by these primary care physicians are probably as ill as those seen exclusively in the specialty mental health sector. From a public health perspective, future policy interventions should aim to improve collaboration between the 2 sectors and enhance the ability of primary care physicians to deliver psychiatric services.
