Bridging the gap in the UK’s National Health Service integrated care systems: insights from a mixed methods implementation evaluation of UCLP-PRIMROSE, a care innovation to reduce physical health inequalities for people with severe mental illness

Key Points

Implementation of UCLP-PRIMROSE shows moderate success, with all teams supporting continued delivery after the evaluation period.
Further resources and pathway simplification are essential for spreading UCLP-PRIMROSE beyond initial areas of good practice, enhancing its reach.
Mixed methods implementation evaluation highlighted the importance of integrated care systems in addressing health disparities.
Sustaining delivery of UCLP-PRIMROSE may lead to significant improvements in health outcomes for those with severe mental illness.

Abstract

Implementation of UCLP-PRIMROSE was moderately successful in a relatively short period of time. At the end of the research, all teams wanted to sustain delivery. However, further pathway simplification and additional resources are required to spread UCLP-PRIMROSE beyond early pockets of good practice.
