Capturing users' experience of UK out-of-hours primary medical care: piloting and psychometric properties of the Out-of-hours Patient Questionnaire

Provision of out-of-hours care in the UK National Health Service (NHS) has changed in recent years with new models of provision and the introduction of national quality requirements. Existing survey instruments tend to focus on users' satisfaction with service provision; most were developed without undertaking supporting qualitative fieldwork. In this study, a survey instrument was developed taking account of these changes in service provision and undertaking supporting qualitative fieldwork. This paper reports on the development and psychometric properties of the new survey instrument, the Out-of-hours Patient Questionnaire (OPQ), which aims to capture information on the entirety of users' experiences of out-of-hours care, from the decision to make contact through to completion of their care management.
