Analysis of risk factors affecting mortality in geriatric patients operated on for hip fractures

Introduction: High mortality rates after hip fracture surgery are an essential health problem. We evaluated the factors affecting mortality in the postoperative 30-day period. Materials and Methods: A total of 906 patients aged 65 years and over who underwent hip fracture surgery were included. The patients were divided into two groups: those who died within 30 days of surgery and those who survived. Demographic data, ASA classifications, comorbidities, method of anesthesia, length of stay in hospitals and intensive care units, and the effects of these parameters on postoperative 30-day mortality were analysed. Results: The postoperative 30-day mortality of the patients was 8.6%. The mean age of the patients who died during this period was 83.49 +/- 6.9 years, while the mean age of the survivors was 78.7 +/- 7.6 years. In our study, age (OD: 1.091; CI 95%, 1.051-1.132), The American Society of Anesthesiologists (ASA) physical status classification (OD: 12.69; CI 95%, 1.074-150.17), coronary artery disease (OD: 0.521; CI 95%, 0.287-0.944), general anesthesia administration (OD: 0.305; CI 95%, 0.140-0.667), and creatinine values (OD: 1.045; CI 95%, 1.114-1.892) were determined to be independent risk factors. Conclusions: Detailed examination of elderly hip fracture patients considering these risk factors and close perioperative follow-up will reduce mortality.
