Mental health, well-being and support interventions for UK ambulance services staff: an evidence map, 2000 to 2020.

BACKGROUND: Prior to COVID-19 there had been a renewed policy focus in the National Health Service on the health and well-being of the healthcare workforce, with the ambulance sector identified as a priority area. This focus is more important than ever as the sector deals with the acute and longer-term consequences of a pandemic.

AIM: To systematically identify, summarise and map the evidence regarding mental health, well-being and support interventions for United Kingdom ambulance services staff and to identify evidence gaps.

METHOD: Evidence mapping methodology of published and grey original research published in English from 1 January 2000 to 23 May 2020 describing the health risk, mental health and/or well-being of UK ambulance services staff including retired staff, volunteers and students. MEDLINE, EMBASE, PsychINFO, CINAHL and AMED databases, plus EThOS, Zetoc, OpenGrey and Google, were searched, alongside hand-searching of grey literature and bibliographies. Information was extracted on study aims, sample, design and methodology, funding source, country and key findings. Included studies were categorised into seven a priori theme areas.

RESULTS: Of 1862 identified articles, 45 peer-reviewed studies are included as well as 24 grey literature documents. Peer-reviewed research was largely observational and focused on prevalence studies, post-traumatic stress disorder or organisational and individual social factors related to health and well-being. Most grey literature reported the development and testing of interventions. Across all study types, underpinning theory was often not cited.

CONCLUSION: To date, intervention research has largely been funded by charities and published in the grey literature. Few studies were identified on self-harm, bullying, sleep and fatigue or alcohol and substance use. Theoretically informed intervention development and testing, including adaptation of innovations from other countries and 24-hour workforces, is needed. This evidence map provides important context for planning of staff well-being provision and research as the sector responds to and recovers from the pandemic.
