"Emergency room" and "mobile response" models of emergency psychiatric services.

The present study surveyed federally-funded emergency psychiatric programs in 33 California community mental health centers (CMHCs). Four aspects of service organization were examined: (1) the availability of various response styles (telephone service, walk-in service, follow-up home visits, mobile initial response); (2) the types of staff providing the service; (3) the location of the programs, and (4) the organizational setting of the CMHCs (consortium or single agency centers). From these characteristics of service organization two contrasting types of emergency psychiatric programs were derived--the "emergency room" and "mobile response" models. The relationship between these two models of service delivery and catchment area demographic characteristics was examined and no remarkable trends emerged. The implications of developing a typology of emergency psychiatric programs are discussed with respect to a scheme for evaluating the relative effectiveness of services and for planning future programs.
