Abstract

Introduction: Hip fractures are of major concern due to the aging population worldwide. Surgery on this vulnerable population carries high risk. Charlson comorbidity index (CCI), has been reported to predict the mortality in these patients. Investigators in this study aimed at studying the prediction effect of CCI on hip fracture surgery complications after controlling other patents' and procedures' related factors.
Methodology: We conducted a retrospective cohort of 1045 patients with hip fractures who were treated surgically at our tertiary care and level 1 trauma Centre between 2010 to 2018. Primary exposure was CCI and primary outcome was in-hospital and 30 days postoperative complications (major and minor). Cox proportional algorithm analysis was done at univariate and multivariable levels to report Crude Relative Risk (RR) and Adjusted Relative Risk (aRR), respectively. Results were reported in line with STROBE criteria.
Results: Exposed group included 867 (83%) of patients with 340 (39%) males. Postoperative complications occurred in 449 (43%) of the patients in exposed group with (62) 6% patients admitted in ICU postoperatively. At multivariable model, CCI was significantly associated with postoperative complications; patients with moderate-severe systemic diseases were 1.45 times (95% CI: 1.05-1.99) at risk of developing postoperative complications as compared to patients with low CCI scores after controlling for other variables in the model. Other significant factors included ASA status and postoperative ICU admission.
Conclusion: CCI can be a good predictor independent variable of postoperative complications after hip fracture surgery. These patients need extra care and counseling to reach an informed decision keeping in mind the benefits versus risks of surgery. We recommend multi-center studies for corroboration.
