ABSTRACT
BACKGROUND: Malnutrition is common and associated with adverse outcomes in geriatric patients with hip fractures. The study aims to evaluate the relationship between the nutritional status and rehabilitation efficiency and functional outcome on discharge in postoperative hip fracture patients. METHODS: We prospectively evaluated 172 postoperative hip fracture patients who were admitted to the community hospital from November 2019 to November 2020. Nutritional status was assessed by the 7-point Subjective Global Assessment (SGA) within 48 h of admission. Patients were assessed for rehabilitation efficiency and functional outcome at the end of their inpatient stay. RESULTS: There were 172 patients recruited with 100 (58.1%) malnourished and 72 (41.9%) well-nourished patients. Patients in the malnourished group were significantly older, needed walking aid assistance prior to sustaining hip fracture, cognitively impaired and had more comorbidities. Malnourished patients had lower rehabilitation efficiency scores (0.27, 95% CI -0.12 - 0.67 vs 1.32, 95% CI 0.88-1.76) and poorer functional outcomes on discharge (OR 21.5, 95% CI 2.45-188.7, p-value <0.001), after adjustment for pre- and post-fracture confounders. CONCLUSION: Malnutrition was present in more than half the postoperative hip fracture patients admitted to a community hospital in Singapore. This study showed that poor nutritional status is associated with significantly lower rehabilitation efficiency and functional outcome on discharge in hip fracture patients. Given the medical, social and economic stakes relating to hip fractures, it is essential to recognise and treat malnutrition in the hospital and community.
