Context: The UK social care sector has come under increased pressure to combat workforce shortages. With international recruitment of professionals impacted by Brexit and the COVID-19 pandemic, social care is in need of innovations to attract, recruit and retain staff.

Objectives: This review aimed to identify (1) innovations to attract, recruit, and retain social workers (professionals working with children and adults to protect them from harm, often as case managers) and the wider social care workforce (workers providing direct practical support to children and adults with their daily activities) and (2) factors influencing staff turnover in the UK context.

Method: Pre-defined inclusion criteria were developed using the SPIDER (Sample, Phenomenon of Interest, Design, Evaluation, Research type) framework. Searches were conducted across three databases and 32 key United Kingdom third sector and government organisations from 2001. In total, 1,835 citations were retrieved and 40 met the eligibility criteria (13 for social workers and 28 for social care workforce). Thematic analysis was used to explore the data and presented across two evidence maps.

Findings: Evaluation evidence was only available for a small portion of innovations identified. Practice learning, fast-track graduate programmes, and apprenticeships may support the retention of social workers, while pre-employment training, national recruitment campaigns, care work ambassadors, and values-based recruitment could help attraction, recruitment, and retention of the wider social care workforce.

Limitations: Most of the included studies were conducted pre-pandemic and mainly relied on descriptive and explorative methodologies.

Implications: Future policy initiatives should include an evaluation strategy from the outset to develop a more extensive evidence base. Funding bodies should offer schemes supporting research in this area.
