The scope to measure the quality and performance of ambulance service care is limited by poor access to follow up patient information and lack of consensus about what to measure. The Prehospital Outcomes for Evidence Based Evaluation (PhOEBE) research programme aims to address these research gaps by identifying potentially important prehospital quality measures and testing these using a prehospital/linked subsequent health service dataset.Methods
We undertook systematic reviews of published and aspirational measures, together with interviews with ambulance service users to identify potential measures. Measures identified from reviews and interviews were prioritised using a multi-stakeholder consensus conference. Measures identified as high priority were further refined and ranked through an expert Delphi method and a service user/patient public involvement workshop. High ranking measures were further assessed against criteria for good outcome measures, including feasibility, importance and relevance, to create a shortlist of measures.Results
Eight high-ranking measures were shortlisted following assessment against criteria for good outcome measures. These were:Conclusion
These measures can be used to assess the impact of care provided by the ambulance service and to support quality improvement through monitoring, audit and service evaluation. Some measures are based on ambulance service data only whereas others require additional linked hospital data.
