The role of ASA score and Charlson comorbidity index in predicting in-hospital mortality in geriatric hip fracture patients

- OBJECTIVE: We aimed to determine the role of American Society of Anesthesiologists (ASA) score and Charlson Comorbidity Index (CCI) in determining inhospital mortality and other factors associated with mortality in patients over 65 years of age who underwent surgery for hip fracture during our study, including the COVID-19 process. PATIENTS AND METHODS: Between January 1st, 2020, and December 31st, 2021, 200 patients over 65 years of age who underwent hemiarthroplasty or internal fixation for hip fracture after low-energy trauma were retrospectively evaluated. RESULTS: Of the 200 patients included in the study, 130 were female and 70 were male. The median ASA score was 3 (IQR: 2-3), and the median CCI was 3 (IQR: 5-7). Forty-two of 137 (68.5%) patients with intertrochanteric fractures and 22 of 63 (31.5%) patients with femoral neck fractures (34.4%) died. The median time to surgery was 4 days (IQR: 3-6). Among chronic diseases, cardiac pathologies were the most common (57%, n=114). There were statistically significant differences in ASA scores (p=0.0001 [z=-5.472]), CCI scores (0.0001 [z=6.156]), presence of cardiac disease [p=0.0001 (chi 2=32.155)] and presence of neurological disease [p=0.04 5 (chi 2=4.007)] compared to mortality. ASA and CCI scores were significantly higher in people with mortality. As a result of the multivariate model established with these factors, which were found to be significant in univariate analyses, only the presence of cardiac disease (p=0.0001) and the increase in CCI scores (p=0.0001) were found to have a statistically significant increasing effect on mortality. CONCLUSIONS: CCI and cardiac pathology were associated with mortality. The type of hip fracture, surgical method, and anesthesia method were not associated with mortality.
