Objective To investigate the impact of nutritional support combined with fast-track rehabili-tation interventions on elderly patients with hip fractures. Methods A total of 76 elderly hip fracture patients admitted to Fujian Provincial Geriatric Hospital from February 2022 to February 2024 were selected and randomly divided into an observation group (nutritional support+fast-track rehabilitation intervention,n=38) and a con-trol group (nutritional support+conventional care intervention,n=38) by a random draw method. The nutritional status,hip joint function,perioperative indicators,and hospitalization conditions were compared between the two groups. Results Before the intervention,there were no significant differences in albumin (ALB) and hemoglobin (HGB) between the two groups (P>0.05). After the intervention,both ALB and HGB levels significantly increased in both groups (P<0.001),with the observation group showing a more significant increase compared to the control group (P<0.001). Similarly,there were no significant differences in Harris scores between the two groups before the intervention (P>0.05). After the intervention,Harris scores significantly improved in both groups (P<0.001),with the observation group showing a more significant improvement compared to the control group (P<0.001). The intraoperative blood loss and postoperative drainage volume were significantly lower in the observation group than in the control group (P<0.001). The average hospital stay was significantly shorter in the observation group than in the control group (P<0.001),while there was no significant difference in average hospital costs between the two groups (P>0.05). Conclusion Nutritional support combined with fast-track rehabilitation interventions is more beneficial than nutritional support combined with conventional care interventions in improving the nutritional status and hip joint function of elderly hip fracture patients,reducing intraoperative blood loss and postoperative drainage volume,and shortening the average hospital stay.
