Application and content of minimum data sets for care homes: A mapping review

Background: Care home residents have complex needs, and minimum data sets (MDSs) provide a unique source of information on their health and wellbeing. Although MDSs were first developed to monitor quality and costs of care, they can make an important contribution to research. Aim: To describe the research applications of data from care home MDSs, and identify key outcome variables and measures used. Design: Mapping review of published empirical studies using data generated from minimum data sets in long term care facilities for older adults. Methods: We performed a comprehensive search of electronic databases (Medline OVID, CINAHL, Embase and ASSIA), using bespoke search strategies to identify English language publications 2011 -2024. Articles were screened by two independent reviewers. They were grouped by study topic and data (on publication date, country, MDS, outcome variables and specific items or measures) were charted without quality assessment. The key features of the data are described in a narrative synthesis. Findings Searches identified 18588 articles published 2011-2024, of which 661 met inclusion criteria. 72% were from the USA, 12% from Canada and the remaining 16% from four European countries, South Korea and New Zealand. The studies encompassed individual resident functioning (e.g. mobility, incontinence), health conditions and symptoms (e.g. depression, pain), healthcare in the home (e.g. prescribing, end of life care), hospital attendances and admissions, transitions to and from care homes, quality of care and systemwide issues. Measures used reflected the content of the major MDSs, but there was a mismatch between the importance of some topics to care homes (e.g. incontinence) and the range of published papers, and limited consensus over how to measure quality of life. Conclusions Care home MDSs are a unique resource to support study of care home residents and impact of interventions over time. They are a powerful resource when linked to other datasets, and as an adjunct to primary data collection This analysis may serve as an accessible guide to the content and applications of MDS, allowing researchers to consider the sort of questions that can be posed and the different components of resident care or experience that can be evaluated.
