Prudent healthcare in emergency departments: a case study in Wales.

To deliver a patient-centred service, emergency departments (EDs) must be efficient, effective and meet the needs of the local population. This article describes a service redesign of unscheduled care in a hospital in Wales, which followed the principles of prudent healthcare to improve patient experiences. Extending the roles of nurse specialist practitioners was a major component of the redesign. Six working groups were established to guide the process, one of which was responsible for working cooperatively with the local community, which was concerned about perceived 'downgrading' of the ED. The service redesign was completed in 2016 and evaluation shows the target for patients being seen in under four hours improved from 88% to 96%, significantly more acute medical admission patients were discharged in less than 24 hours, and patient satisfaction increased overall.
