Nutrition status and functional prognosis among elderly patients with distal radius fracture: a retrospective cohort study
Abstract Background Distal radius fractures (DRF) are common in the elderly and are typical of hand fractures during falls. Malnutrition has also been identified as a poor prognostic factor in elderly patients with fractures. However, the relationship between nutritional status and subsequent falls and functional prognosis in the elderly DRF is not clear. The aim of the present study was to investigate the association between nutritional status and functional prognosis in patients with elderly DRF. Methods Study participants included 229 outpatients who required surgical treatment with DRF. The patients’ clinical information, including age, sex, body mass index, bone mineral density, Geriatric Nutritional Risk Index (GNRI), total number of drugs being treated with on admission, use of drugs for osteoporosis, comorbidity severity, Barthel Index(BI), presence of subsequent falls, fracture type, postoperative follow-up period, and Mayo wrist score was reviewed. The subjects were further divided into two groups according to their GNRI: the malnutrition group and the normal group. Propensity score matching was used to confirm the factor affecting BI and subsequent fall. Results Thirty-one patients (13.5%) were malnutrition before surgery for DRF. According to the multiple liner regression analysis, GNRI positively affected BI efficiency (β=0.392, 95% confidence interval, 0.001 to 0.351, p=0.039). Furthermore, on logistic regression analysis, subsequent fall was correlated with the serum albumin (odds ratio=0.033, 95% confidence interval,0.002 to 0.477, p=0.012). Conclusion Malnutrition impaired the improvement of the activity of daily living (ADL) and increased the incidence of subsequent fall. Improvement of nutritional status before DRF surgery may further improve ADL and prevent falls.
