From the 146 interventions offered under POPP, we selected eight for an in-depth study of hospital use
• Support workers for community matrons
• Intermediate care service with generic workers
• Integrated health and social care teams
• Out-of-hours and daytime response service
• Four different short-term assessment and signposting services

We linked participants to hospital data at the person level

The importance of a control group: regression to the mean in the absence of a specific intervention

We selected controls retrospectively from other areas of England
• In the absence of a randomised controlled trial, we compared participants to matched controls
• We ensured that controls were similar to participants in terms of:• age• sex• area deprivation• recorded health diagnoses• prior hospital use• predicted risk score
• There may still be differences that we cannot observe
