ABSTRACT
With the aging of the Chinese society and the population, the incidence of hip fractures in the elderly is increasing significantly. Elderly patients have various basic diseases and decreased organ compensatory capacity, which increase the risks related to surgery and anesthesia, increase the incidence of postoperative complications and mortality, and affect the recovery process of patients. Malnutrition is one of the main causes of hip fractures in elderly patients, and it is also a major factor predicting the prognosis of patients. Elderly patients with hip fractures are considered at high risk of malnutrition. Malnutrition can lead to adverse clinical outcomes, such as increased mortality and complications, prolonged hospital stays, and increased hospital costs. Elderly patients with hip fracture should be routinely screened for nutritional risk. Those with malnutrition or nutritional risk, should be given nutritional support treatment. And conduct assessments and optimizations of nutritional support treatmentby observing the prognosis indicators such as complication rate, mortality, and rehabilitation status. At present, orthopedic surgeons who are the main body of elderly hip fracture treatment do not pay enough attention to the nutritional status of patients. Many elderly hip fracture patients undergo surgery while their malnutrition status has not improved. Therefore, it is important to improve their prognosis that strengthen the perioperative nutritional management of elderly patients with hip fracture. Domestic research on the nutritional status of elderly hip fracture patients started late. Many medical institutions have not carried out routine nutritional screening and active nutritional support treatment for elderly hip fracture patients, and there is also a lack of relevant clinical research and data statistics in the nutritional support and treatment of elderly patients with hip fractures. This article describes the current research status of nutritional risk screening and nutritional support treatment for elderly patients with hip fracture at home and abroad. However, due to differences in ethnicity, lifestyle, religious culture, and eating habits in various regions, foreign research data may not be suitable for domestic patients. Therefore, this article provides a reference for the research on perioperative nutritional screening and nutritional treatment of elderly hip fracture patients, and establishes a nutritional management plan suitable for elderly hip fracture patients in China.
