A rapid review of the effectiveness of interventions and innovations relevant to the Welsh NHS context to support recruitment and retention of clinical staff.

The National Health Service (NHS) is experiencing an acute workforce shortage in every discipline, at a time when waiting times are at a record high and there is a growing backlog resulting from the COVID-19 pandemic. This Rapid Review aimed to explore the effectiveness of interventions or innovations relevant to the Welsh NHS context to support recruitment and retention of clinical staff. The review is based on the findings of existing reviews supplemented by a more in-depth evaluation of included primary studies conducted in the UK or Europe. The review identifies a range of interventions that can be used for enhancing recruitment and retention in Wales, particular in rural areas, and supports multiple-component interventions. The findings highlight the importance of providing and locating undergraduate and post graduate training in rural locations. The findings also corroborate the use of bursary schemes for training, such as those already available for Nursing in Wales. Further, more robust evaluations, based on comparative studies, are required to assess the effectiveness of interventions to support recruitment and retention of clinical staff. There was limited evidence on interventions aimed at allied health professionals. Most of the primary studies included in the reviews used cohort (pre-post test) or cross-sectional designs. Most studies lacked a comparison group and did not use statistical analysis
