To analyze the risk factors associated with mortality within 1 year after surgery in elderly patients with hip fracture and to assess the value of the age-corrected Charlson comorbidity index in predicting this mortality risk.

To investigate the determining risk factors for 1-year postoperative mortality in elderly patients with hip fracture and to assess the efficacy of the age-adjusted Charlson comorbidity index (ACCI) in predicting the risk of death. This study adopted a retrospective analysis method to focus on 652 elderly patients who underwent hip fracture surgery between January 2018 and November 2022 in our hospital. By systematically combing the patients' medical records, relevant data were collected and analyzed in depth for their association with morbidity and mortality rates within 1 year.
