Kim CY, et al. - In this study, the accuracy of the Elixhauser Comorbidity Measure (ECM), the Charlson Comorbidity Index (CCI), and the Combined Comorbidity Score (CCS) were compared for prognosticating adverse events and postoperative discharge destination after surgical treatment of geriatric patients with acetabular fractures. Between 2002 and 2014, researchers carried out to search the National Inpatient Sample for individuals over the age of 65 yr who had fixation of an acetabular fracture. They applied logistic regression models of basic demographic variables and the ECM, CCI, or the CCS to prognosticate inpatient mortality, complications, extended length of stay, and discharge disposition. Utilizing the C-statistic, the predictive discrimination of each model was assessed. For the assessment of postoperative complications, the CCS was found to be the best predictive model, followed by the ECM then CCI. The outcomes may help in preoperative decision-making for geriatric individuals with acetabular fractures.
