Summary: Background & Aims: Currently, there is lack of universal consensus on the use of effective malnutrition screening tools. Although malnutrition, frailty and physical disability are interrelated and associated with mortality in older people, there is a paucity of research in care home settings. With a high co-prevalence of these conditions, understanding their interconnectedness can provide a holistic view of an older person's health condition. The purpose of this study was to examine the prevalence of malnutrition (and risk) frailty and physical disability among care home residents using different methods, as well as the associations between markers of malnutrition (MUST and MNA-SF), physical function (Barthel Index, BI), frailty (Edmonton Frailty Scale, EFS), and all-cause mortality in care home residents. Methods: In Lincoln, UK, 508 residents from care homes underwent screening for malnutrition (MNA-SF and MUST), frailty (EFS), and physical function (BI) as part of standard comprehensive geriatric assessment (CGA) between November 2015 and January 2018. Prevalence of conditions were assessed and MNA-SF, MUST, EFS, and BI-specific survival in each category were compared using Kaplan-Meier survival analysis (KMSA) with log-rank test. Multivariable analyses were conducted using the Cox proportional hazard model to identify prognostic factors that were statistically significant in care home residents. Results: There was significant discordance between malnutrition risk measured by MUST and MNA-SF. The percentage of patients ‘at risk’/‘medium risk’ and ‘malnourished’/‘high risk’ was 25.3%/49.9% for MNA and for 19.6%/31.57% for MUST. The prevalence of frailty measured by EFS was high with the percentage of residents with severe frailty being 70.9%. Only 8.6% of patients were functionally independent. The association between malnutrition risk (MUST) and mortality was not significant. MNA-SF appeared to be a better tool at predicting mortality in older care home residents (p |
