Functional recovery of older people with hip fracture: does malnutrition make a difference?

Abstract Aim To report a study of the effects of protein‐energy malnutrition on the functional recovery of older people with hip fracture who participated in an interdisciplinary intervention. Background It is not clear whether protein‐energy malnutrition is associated with worse functional outcomes or it affects the interdisciplinary intervention program on the functional recovery of older people with hip fracture. Design A randomized experimental design. Methods Data were collected between 2002–2006 from older people with hip fracture ( N = 162) in Taiwan. The generalized estimating equations approach was used to evaluate the effect of malnutrition on the functional recovery of older people with hip fracture. Results The majority of older patients with hip fracture were malnourished (48/80, 60% in the experimental group vs. 55/82, 67% in the control group) prior to hospital discharge. The results of the generalized estimating equations analysis demonstrated that subjects suffering from protein‐energy malnutrition prior to hospital discharge appeared to have significantly worse performance trajectories for their activities of daily living, instrumental activities of daily living, and recovery of walking ability compared with those without protein‐energy malnutrition. In addition, it was found that the intervention is more effective on the performance of activities of daily living and recovery of walking ability in malnourished patients than in non‐malnourished patients. Conclusion Healthcare providers should develop a nutritional assessment/management system in their interdisciplinary intervention program to improve the functional recovery of older people with hip fracture.
