PURPOSE

The influence of rurality on the duration of untreated psychosis (DUP) in first-episode psychosis (FEP) is poorly understood. We investigated factors associated with FEP in rural/urban settings and whether there are rural/urban differences in DUP and the mode (speed) of onset of psychosis.

METHODS

We used the Cambridgeshire and Peterborough NHS Foundation Trust Research Database (CPFTRD) to identify all persons presenting to an early intervention for psychosis service with FEP between 2013 and 2015. We performed descriptive statistics and multivariable linear and multinomial regression to assess the relationships between the study outcomes and the independent variables.

RESULTS

One hundred and fifty-five FEP patients were identified, with a mean age of 23.4 (SD, 5.3) years. The median DUP was 129.0 (IQR: 27.5-524.0) days. In rural areas, FEP patients were more likely to be employed and live with family than those in urban areas. A longer DUP was observed among patients with an insidious onset of psychosis compared with an acute onset (619.5 (IQR: 333.5-945.0)) vs. (17.0 (IQR: 8.0-30.5)) days respectively, p < 0.0001. We found evidence that the mode of onset of psychosis differed by employment status and living circumstances. There was insufficient evidence of rural/urban differences in DUP and mode of onset of psychosis.

CONCLUSIONS

Our results suggest that the mode of onset of psychosis is an important indicator of treatment delay and could provide vital information for service planning and delivery. Sociodemographic variations in FEP exist in rural populations, and our findings are similar to those observed in urban settings.
