Patient experience is a crucial measure of the quality of patient care in healthcare settings. It encompasses all the patient’s interactions with staff and their exposure to equipment, procedures, environment and service structure during one care episode. Capturing patient experience is one way of ensuring that patients’ voices are heard and can form the basis of an audit or service improvement project designed to evaluate or enhance the patient-centredness of care. Nurses are increasingly involved in audits and service improvement projects, so it is important that they understand what patient experience is, how it differs from patient satisfaction and what approaches can be used to measure it. This article defines patient experience, describes data collection methods and discusses factors to consider when planning to collect patient experience data, notably the validity, reliability and rigour of the data collection tool.
