Case Management Knowledge Item 02: Results from HRSA/HAB's SPNS Innovative Models of Care

Knowledge Item: CA-Case Management-02
Retention in Psychosocial Services as a Function of Site, Gender, Service Needs and Vulnerabilities, and Case Management Status

Cox regression for proportional hazards, a type of survival analysis, was used to study the time that 1735 clients in 10 programs were retained in psychosocial services. Pooling the data in the 10 programs, and controlling for site differences, the combined effects of gender, ethnic-racial background, age, and the presence or absence of case management are shown. Pooling across all projects, the only effects are for site differences and case management. This analysis shows that case management is associated with longer program retention even after controlling site and demographic differences.

The strong case management effects on program retention cannot be explained by site or need and vulnerability differences in the clients who did or did not receive case management services.

The following four scatterplots summarize the relationship between the total number of service needs and vulnerabilities index and the total stay of the client in the program. Four groups are separately shown (from the upper left, clockwise: still in program on last day of data collection, no case management; terminated from program, no case management; terminated from program, case management; still in program on last day of data collection, case management. There is only a very tiny relationship between the total number of needs and length of stay in program.
