The CLAHRC and its project partners, Jannsen Healthcare Innovation and Oxford AHSN’s Early Intervention in Psychosis Network[1], initiated a project to look at health service use by psychosis patients in the Thames Valley, over a three-year period.

The project used Jannsen Healthcare Innovation’s unique ‘case identification and data linkage’ methodology with data from routine mental health system and secondary care physical health system databases – the Mental Health Minimum Data Set (MHMDS) and Hospital Episodes Statistics (HES) databases, respectively.

This data then served as the basis for an economic evaluation of the services.

More than 4,640 patients were identified for the study and 20 per cent were found to have been treated under an EIP service. Rates of admission to mental health hospitals, length of stay, employment outcomes and A&E attendances were compared between those who were treated in an EIP service, and those who were not.
