Determining the effect that consultation-liaison psychiatry in primary care has on family physicians' psychiatric knowledge and practice

Abstract

The impact of a community-based consultation-liaison (C-L) psychiatry service on family physicians' levels of psychiatric knowledge, diagnostic and treatment confidence, and patterns of referral to mental health care agencies was evaluated over a 12-month period. The physicians with long-term access to the C-L service had higher levels of psychiatric knowledge than those with short-term or no access. However, there was no evidence that the C-L service produced changes in the physicians' levels of clinical confidence, referral likelihood, or psychiatric knowledge during the evaluation period. Significant predictors of psychiatric knowledge were age (younger) and gender (women). The participating physicians were highly satisfied with the service and preferred it over other possible referral agencies. However, community C-L services in family practice appear to have a limited role in the provision of psychiatric care and are not an efficient way for improving family physicians' levels of psychiatric knowledge or altering their practices. The appropriate role of community C-L psychiatry may be as one component of a comprehensive service-delivery strategy integrated within ongoing, formal family-physician educational programs.
