Case Management Models for Persons Who Are Homeless and Mentally Ill: The ACCESS Demonstration Project

Persons who are homeless and mentally illpresent unique challenges to service providers and humanservice systems. In vivo case management approaches suchas assertive community treatment (ACT) have shown promise in engaging this population. This paperexplores case management models employed within theACCESS program, a five year, 18-site demonstrationprogram enriching services for homeless persons with serious mental illness. We describe theimplementation of case management with ACCESS programsand determine the extent of variation across sites usinga measure of fidelity to ACT. While programs reported using four models, much similarity was foundamong programs on multiple dimensions.
