Is there a Correlation Between the Distance to Healthcare Facilities and Postoperative Complications after Achilles Tendon Rupture? A Geospatial Study

Abstract

Category: Ankle; Other Introduction/Purpose: Geospatial access to healthcare is defined as the ability of patients to obtain healthcare services based on their locations. Therefore, we aimed to investigate patients’ proximity to healthcare and its correlation with the complications of surgically treated Achilles tendon rupture (ATR), including venous thromboembolism (VTE), re-rupture, and wound dehiscence. The outcome of this study can help providers and policy makers to determine the equity of healthcare for these patients in the area under their coverage. Methods: We included 426 patients who lived in the United States (US) tri-state area who received surgical treatment for ATR. We used patient and hospital addresses and zip codes to calculate the distances to healthcare centers. A geographic information system (GIS) platform analysis in the tri-state was completed using Maptive, powered by Google Maps, to create heat maps displaying the geographical distribution of patients treated for ATR with and without complications (Figure 1). The Shapiro–Wilk test was used to determine normal distribution. Mann–Whitney U test was used to compare the groups with and without complication. The point biserial correlation test was used to determine any correlations between driving distance and the incidence of complications (p < 0.05 was considered significant). Results: The average driving distance to the patient’s specific healthcare center was 62.16 ± 76.54 km. There was no significant difference between the distances for patients with and without overall complications (p = 0.65), with and without VTE (p = 0.70), with and without re-rupture (p = 0.84), and with and without wound problems (p = 0.36). No correlation between complications and the distance to healthcare centers was found (p = 0.65; Table 1). Conclusion: Geospatial information is important within the context of healthcare accessibility and can provide crucial guidance to healthcare planning for patients and healthcare policymakers. Although this study showed that distance to healthcare facilities did not lead to significantly higher complication rates amongst ATR patients, it does not resolve the need for further studies looking at a larger population and broader geographical segments. These studies can be used to assess the equity of healthcare in specific areas and make modifications if needed.
