The NHS in England has dedicated Early Intervention in Psychosis (EIP) services to treat first episode psychosis. Although recommended by NICE, there is inadequate information on EIP service costs, benefits and economic impact. The research project aimed to demonstrate the costs, outcomes and economic impact of EIP services.

In a longitudinal retrospective observational study, we used large data set over a 3-year period after data linkage across care settings and advanced statistical techniques to analyse panel data and to control for confounding.

Our study suggests that EIP services, as implemented in the healthcare system in England, are associated with better health and social outcomes, and reduced costs. They could save the NHS about £33.5 million per year.
