Exploring patient safety outcomes for people with learning disabilities in acute hospital settings: a scoping review

OBJECTIVES: To produce a narrative synthesis of published academic and grey literature focusing on patient safety outcomes for people with learning disabilities in an acute hospital setting. DESIGN: Scoping review with narrative synthesis. METHODS: The review followed the six stages of the Arksey and O’Malley framework. We searched four research databases from January 2000 to March 2021, in addition to handsearching and backwards searching using terms relating to our eligibility criteria—patient safety and adverse events, learning disability and hospital setting. Following stakeholder input, we searched grey literature databases and specific websites of known organisations until March 2020. Potentially relevant articles and grey literature materials were screened against the eligibility criteria. Findings were extracted and collated in data charting forms. RESULTS: 45 academic articles and 33 grey literature materials were included, and we organised the findings around six concepts: (1) adverse events, patient safety and quality of care; (2) maternal and infant outcomes; (3) postoperative outcomes; (4) role of family and carers; (5) understanding needs in hospital and (6) supporting initiatives, recommendations and good practice examples. The findings suggest inequalities and inequities for a range of specific patient safety outcomes including adverse events, quality of care, maternal and infant outcomes and postoperative outcomes, in addition to potential protective factors, such as the roles of family and carers and the extent to which health professionals are able to understand the needs of people with learning disabilities. CONCLUSION: People with learning disabilities appear to experience poorer patient safety outcomes in hospital. The involvement of family and carers, and understanding and effectively meeting the needs of people with learning disabilities may play a protective role. Promising interventions and examples of good practice exist, however many of these have not been implemented consistently and warrant further robust evaluation.
