Abstract: | BackgroundPrevious research has highlighted disparities in access to and outcomes following shoulder arthroplasty. The purpose of this study is to compare travel distance for primary vs. revision surgery and to determine the relationships between travel distance to undergo revision shoulder arthroplasty and patient demographics and postoperative adverse outcomes. We hypothesized that older patients, those with increased medical comorbidities, and those with greater financial resources would travel farther for surgery.MethodsThe Healthcare Cost and Utilization Project, American Hospital Association, and UnitedStatesZipCodes.org Enterprise data sets were compiled to collect data on patient demographics, operation performed, and postoperative adverse outcomes. Population-weighted zip code centroid points of patients’ residences as well as hospital coordinates were used to approximate the distance traveled to undergo shoulder arthroplasty. Kruskal-Wallis tests and logistic regression analyses were used to analyze the relationship between travel distance and patients’ demographics and postoperative outcomes.ResultsPatients traveled farther to undergo revision shoulder arthroplasty than to undergo primary shoulder arthroplasty (P = .0001). Among patients who underwent revision operations, older age (P = .0001) and increased medical comorbidities (P = .003) were associated with decreased travel distance. White patients and those with commercial insurance traveled farther to receive care (P = .0001). There were no clinically significant associations between postoperative outcomes following revision surgery and travel distance.ConclusionPatients may travel farther to undergo revision surgery owing to patient preferences or because these complex operations are performed at fewer centers. Younger and healthier patients, white patients, and those with commercial insurance plans traveled farther to receive care. Future work is needed to determine the underlying causes of these disparities and whether it is patient preferences or systemic factors such as hospital density or access to high-quality health insurance that are influencing access to this specialized surgical care. |
