Assessing the value of assertive outreach - Qualitative study of process and outcome generation in the UK700 trial

Background It is unclear why intensive case management (ICM) failed to reduce hospitalisation in the UK700 trial. Aims To investigate outcome generation in the UK700 trial. Method A qualitative investigation was undertaken in one UK700 centre. Results Both intensive and standard case management practised individual casework, employed assertive outreach with comparable frequency, and performed similarly in the out-patient management of emergencies and inpatient discharge. However, ICM was advantaged in managing some noncompliance and undertaking casework that prevented psychiatric emergencies. Absence of team-based management and bureaucratised access to social care limited the impact of these differences on outcomes and the effective practice of assertive outreach, although this was relevant to only a sub-population of patients. Conclusions The impact of ICM was undermined by orgainisational factors. Sensitive anticipatory casework, which prevents psychiatric emergencies, may make ICM more effective than an exclusive focus on assertive outreach. Our findings demonstrate the value of qualitative research in evaluating complex interventions. Declaration of interest None. Funding detailed in Acknowledgements.
