This article describes a model that brings together the chemical depen
dency, mental health, and primary care services of a staff model HMO f
or the purpose of establishing a primary care clinic-based program to
assist physicians in early detection of chemical dependency and freque
nt psychiatric disorders. The model creates a partnership between a ma
ster's-level professional social worker (MSW) and a designated family
physician from the clinic. Their focus is on provider education, consu
ltation, and on assisting patients with referrals to the appropriate s
ervices. Parameters of success include changes on referral patterns, u
se of the MSW's services, and clinic satisfaction. In addition, there
are indications that early intervention has had a positive impact on s
ubsequent use of other health care systems' resources.
