We aimed to verify the effectiveness of the Nottingham Hip Fracture Score (NHFS) for predicting postoperative outcomes following hip fracture surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a single\u2010center and retrospective analysis. A total of 702 elderly patients with hip fractures (age\u2009\u2265\u200965\u2009years old) who received treatment in our hospital from June 2020 to August 2021 were selected as the research participants. They were divided into the survival group and the death group based on their survival 30\u2009days after surgery. The multivariate logistic regression model was used to identify the independent risk factors for the 30\u2010day mortality after surgery. The NHFS and American Society of Anaesthesiologists (ASA) grades were used to construct these models, and a receiver operating characteristic curve was plotted to assess their diagnostic significance. A correlation analysis was performed between NHFS and length of hospitalization and mobility 3 months after surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were significant differences in the age, albumin level, NHFS, and ASA grade between both groups (p\u2009&lt;\u20090.05). The length of hospitalization in the death group was longer than the survival group (p\u2009&lt;\u20090.05). The perioperative blood transfusion and postoperative ICU transfer rates in the death group were higher than in the survival group (p\u2009&lt;\u20090.05). The death group's incidence of pulmonary infections, urinary tract infections, cardiovascular events, pressure ulcers, stress ulcers with bleeding, and intestinal obstruction was higher than the survival group (p\u2009&lt;\u20090.05). The NHFS and ASA III were independent risk factors for the 30\u2010day mortality after surgery, regardless of age and albumin level (p\u2009&lt;\u20090.05). The area under the curve (AUC) of the NHFS and ASA grade for predicting the 30\u2010day mortality after surgery was 0.791 (95% confidence interval [CI] 0.709\u20130.873, p\u00a0&lt;\u20090.05) and 0.621 (95% CI 0.477\u20130.764, p\u00a0&gt;\u20090.05), respectively.
