Physical health assistance in early recovery of psychosis: Study protocol for a randomized controlled trial.

Aim: Young people with psychotic disorders have poorer physical health compared to their healthy peers, a state compounded by the metabolic side-effects of antipsychotic medications. To address this, Orygen Youth Health has introduced physical health services including exercise physiologists and dieticians. These services are typically coordinated by the case manager and doctor. It is not yet known whether a treating team member dedicated to physical health will improve engagement, adherence and outcomes with these services. Hence, the protocol is presented here for a trial to evaluate the effect of including a physical health nurse in the care of young people with first-episode psychosis.

Methods: This will be a single-blind randomized controlled trial that includes 15- to 24-year-olds with first-episode psychosis who have just commenced (within 30 days) antipsychotic medication. The primary outcome will be the event of clinically significant weight gain (≥7% body weight). Participants will be assigned either a physical health nurse in their treating team (in addition to the case manager and doctor) for a 12-week period, or treatment as usual (case manager and doctor). Research assessments will be conducted at baseline, 12 and 26 weeks. Activity trackers worn by participants for the study's duration will measure sleep and physical activity.

Conclusion: The present study will determine whether a physical health nurse will facilitate participants in attending and engaging in physical health interventions and whether this will be associated with physical health improvements or the prevention of worsening physical health.
