Individuals with serious mental illness (SMI) are at considerably higher risk for morbidity and mortality than those in the general population. The current pilot trial is a preliminary examination of a peer health navigation intervention for improving health and healthcare utilization called the Bridge. Twenty-four individuals with SMI were randomly assigned to either peer navigation or treatment as usual (TAU). Navigators encouraged development of self-management of healthcare through a series of psychoeducation and behavioral strategies. Outcomes included a range of health consequences, as well as health utilization indices. After 6 months, compared to the TAU group, participants receiving the intervention experienced fewer pain and health symptoms. Participants changed their orientation about seeking care to a primary care provider (44.4 % vs. 83.3 %, χ(2) = 3.50, p < .05) rather than the emergency room (55.6 % vs. 0 %, χ(2) = 8.75, p < .01). Therefore, the Bridge intervention demonstrated considerable promise through positively impacting health and healthcare utilization.
