Medical Practice Variations in Mental Health and Addictions Care

Abstract

International audienceThis chapter provides an overview of the practice variations in care delivery for mental health and addictive disorders and some of the system-level funding and structural factors that contribute to such variation. Practice variations are described for five populations, along with their expected clinical picture and service needs:Children and adolescentsThe elderlySevere mental illnessMild/moderate illnessSubstance use disordersThese variations occur in a system-level climate which has been transformed over the past decades because of a fundamental change in how appropriate care is defined. Specifically, Western countries have been shifting from institutional to more community-based care – a process labeled “deinstitutionalization.” National differences in how services are funded and organized in light of deinstitutionalization are described. Pending gold-standard outcome indicators such descriptions allow more in-depth examination of what the potential drivers for system change are and how different funding and structure configurations might be compared and evaluated

Case-Mix Classification for Mental Health Care in Community Settings: A Scoping Review

“…For mental health, the delivery of care can take place in multiple settings as de-institutionalization has shifted mental health services from facility-based inpatient care to community-based care. 11,12 Facility-based inpatient care provides intensive observation, diagnosis, and treatment typically in times of crisis, 13 and usually requires a hospital admission with one or more overnight stays. 14 Community-based care typically employs a care team that provides a wider range of services, including both urgent and ongoing care, such as assertive treatment services, crisis management, outreach, recovery, housing, occupation training, and day programs.…”
