Psychiatric referral rates and the influence of on-site mental health workers in general practice.

Psychiatric referral rates vary widely between different general practices. To increase our understanding of this variation, we conducted a one-year prospective observational study of outpatient psychiatric referrals made by all general practices (622 referrals from 29 practices) within the catchment area of one inner-city psychiatric service. Contrary to our hypothesis, practices with higher allocations of on-site mental health workers did not have lower psychiatric referral rates.
