Virtual wards (VWs) involve monitoring and treating people at home as an alternative to admission to hospital. Phase 1 is in-depth qualitative work to comparison the different VW models in place within SYB, including the context for their implementation. This work will also explore staff experiences of the VWs. Phase 2 will analyse routine clinical and patient data collected from each VW site to describe the clinical activity and patient outcomes of the VW. The average costs of VWs compared to standard inpatient care will also be assessed.
