This paper presents a model, based upon a series of state-level initiatives in the Commonwealth of Pennsylvania, for improving coordination between the aging and mental health systems to better serve elderly persons with mental health problems. The mental health needs of the elderly are discussed and service delivery obstacles - systemic, individual, and agency/staff - are reviewed and synthesized. Policy initiatives by the Commonwealth of Pennsylvania that relate to these issues are presented as a case study, with a focus upon a series of regional conferences held around the state for providers in the aging and mental health networks to encourage better coordination of services. The process and outcomes of these conferences are discussed, together with an analysis of the implications for practice, policy, and teaching.
