PHMC’s role as a pioneer in providing services for those with HIV/AIDS was established through the development of a uniform case management system. From 1988 to 1991, PHMC served as the lead agency for the AIDS Services Demonstration Project, funded by the Health Resources and Services Administration, which served the eight-county Philadelphia Metropolitan Statistical Area in Pennsylvania and New Jersey. As lead agency for the project, PHMC maintained a county-based, centralized, coordinated case management system designed to improve the access of persons infected by HIV to an appropriate continuum of services. PHMC worked alongside case management providers, early intervention counseling agencies and medical and social service providers throughout the entire eight-county area. Through a data management information system and data collection instruments developed by PHMC, providers were able to track services for individual clients and document any barriers to care. Later, this system was incorporated into the regional Ryan White AIDS services plan, which coordinated a five-county regional AIDS case management system administered from 1991 to 1994.
