Measuring Healthcare Experiences Among People With Intellectual Disability: A Rapid Evidence Synthesis of Tools And Methods

Objectives: Patient-reported experience measures (PREMs) collect essential data for service and system-wide quality improvement and performance monitoring toward value-based care. However, the experiences of people with intellectual disability, who have high healthcare utilization couple with poorer outcomes, are often omitted from system-wide PREMs and service-wide PREMs data. The use of PREMs instruments for data collection among people with intellectual disability has not been explored. This review aimed to identify and synthesize measurement tools and approaches that have been used to gather patient-reported experience data from people with intellectual disability. Methods: Rapid evidence assessment was used, in which comprehensive search strategies were applied to electronic databases and gray literature. Narrative synthesis was used with the included articles to address the review aim. Results: A total of 48 documents were included; 26 peer-reviewed journal articles and 22 articles from gray literature. Patient-reported experiences have been gathered from people with intellectual disabilities in relation to specific services or encounters, predominantly using qualitative methods. To date, there is an absence of targeted service- or system-wide surveys. Existing clinic- and condition-specific instruments provide insight for broader application. Conclusions: Patient experience assessment among people with intellectual disability requires consideration of (1) how individuals are identified and approached, (2) the content, design and structure of measurement instruments, and (3) the process by which data are collected, and (4) how it may be applied to create change. Despite the collection of patient experience data from people with intellectual disability, there is little research available about how this information is later used to support health service improvement. Applying PREMs for quality improvement is critical to realize the improvements to healthcare provision required for people with intellectual disability toward equitable care quality.
