London DA, Cagle PJ, Parsons BO, et al. - An aging and more comorbid cohort, along with current trends of elevated operative intervention, implies that there could be an increase in resource utilization caring for these patients. This study was undertaken to investigate these trends and evaluate the effect that the comorbidity burden has on resource utilization. Researchers included data on 83,975 patients with proximal humerus fractures (PHFs) from the Premier Healthcare Claims database (2006 to 2016) and stratified by the Deyo-Charlson index. The data demonstrate that in individuals with PHFs, elevated comorbidity burden coincides with substantial increases in resource utilization in patients receiving surgical and nonsurgical treatments. The results of this study considered that combined with known increases in operative intervention, trends in increased comorbidity burden may have profound effects on the cohort level, and resource utilization for those with PHFs, particularly because of the use of bundled payment strategies for fractures increases.
