The role of referral pathway to early intervention services for psychosis on 2-year inpatient and emergency service use

Abstract

This study examined the relationship between terminal referral source and subsequent urgent health service use in a Canadian early intervention service (EIS) for psychosis. Administrative health record data of emergency and inpatient mental health service use over a 2-year follow up from entry to EIS were retrospectively analyzed (n = 515). Negative binomial regression models were used to assess for the relationship between referral source and care outcomes. Compared to those referred from primary care services, the rate of urgent health care use was significantly greater for individuals referred to early intervention services from urgent care services while accounting for social and occupational functioning and psychotic symptom severity. Findings suggest that those referred from urgent services may be at an increased risk for subsequent urgent health care use while attending EIS for psychosis. Further research examining this relationship while incorporating additional relevant predictors is needed.
