Retention in Psychosocial Services Knowledge Item 05: Results from HRSA/HAB's SPNS Innovative Models of Care

Knowledge Item: CA-Retention in Psychosocial Services-05
Program-Specific Retention Curves

Cox (proportional hazards) and Kaplan-Meier survival analysis was used to study the time that 2063 clients, in 10 programs, were retained in psychosocial services designed to support their medical treatment. Combining data from the ten programs, the mean estimated time of program retention is 710.73 days (standard error = 17.41 days). The median time of retention in program is 529 days.

There are significant variations among the programs in the degree to which they retain their clients in psychosocial services. This Knowledge Item shows site-specific curves.

Note: The survival curve shown above differs from those shown in Retention Items 01-04 in that it is a "raw" set of curves derived from a Kaplan-Meier analysis rather than fitted curves from a Cox proportional hazards regression. The "raw" curve is shown in order to give a closer sense of the differences between the projects.

The next curve has been fitted through Cox regression.
