This presentation documents the process of the implementation of a System of Care in British Columbia, 1973-1977. Several mechanisms of implementation are described, including the Monitoring System, Fiscal Accountability, Program Liaison, Program Guidelines, Program Description Manual, Classification System, Funding Agreement, and Regionalization. The emphasis is on the process of consultation with line staff. Generation of descriptions of the components of the System of Care from the programs already in existence are discussed. The format for thinking about programs used for the Guidelines is extensively described. This format is composed of six key questions, the answers to which form the basis for the three main components of a System of Care: Detoxication, Out-Patient, and Residential Services. These questions are: (1) What is the rationale for this program? (2) What are the program objectives and goals? (3) Who is the client? (4) What happens to the client in treatment? (5) What is the staff organization and how does it function? and (6) What is the referral path and the follow-up procedure? These questions may also be used as guides for staff development and for program assessment. (Author/MFD)
