Acute sarcopenia changes following hospitalization: influence of pre-admission care dependency level

Abstract Introduction Hospitalization is associated with acute changes in sarcopenia status older people, but the influencing factors are not fully understood. Pre-admission care dependency level as a risk factor has yet been investigated. Objective Evaluate if pre-admission an independent predictor of following hospitalization. Setting and subjects Data came from Sarcopenia 9+ EAMA Project, European prospective multi-centre study. For this study, 227 hospitalised people were included four different hospitals Belgium, Spain Poland, between 18 February 2019 5 September 2020. Methods at admission discharge calculated using combined score (desirability value) based on muscle mass (calf circumference), strength (grip) function (walking speed). Ratio to was outcome ratio; 1.00 meaning no difference). Predictor variable level, classified into three groups: living home, dependent home home. Linear regression models applied, considering potential confounders. Results Mean desirability ratio for (‘middle group’) lower (0.89) compared (0.98; coefficient ?0.09 [95% CI ?0.16, ?0.02]) patients (1.05; ?0.16 ?0.01, ?0.31]). Adjusting confounders or another statistical approach did affect main results. Conclusion Dependent higher deterioration In-depth studies investigating causes interventions these findings needed.
