BackgroundRegional variation in complex healthcare is shown to negatively impact health outcomes. We sought to characterize geographic variance in esophageal cancer operation in Michigan.Study DesignData for patients with locoregional esophageal cancer from the Michigan Cancer Surveillance Program from 2000 to 2013 was analyzed. We reviewed the incidence of esophageal cancer by county and region, and those with locoregional disease receiving an esophagectomy. Counties were aggregated into existing state-level "urban vs rural" designations, regions were aggregated using the Michigan Economic Recovery Council designations, and data was analyzed with ANOVA, F-test, and chi-square test.ResultsOf the 8,664 patients with locoregional disease, 2,370 (27.4%) were treated with operation. Men were significantly more likely to receive esophagectomy than women (p < 0.001). Likewise, White, insured, and rural patients were more likely than non-White (p < 0.001), non-insured (p = 0.004), and urban patients (p < 0.001), respectively. There were 8 regions and 83 counties, with 61 considered rural and 22 urban. Region 1 (Detroit metro area, southeast) comprises the largest urban and suburban populations; with 4 major hospital systems it was considered the baseline standard for access to care. Regions 2 (west; p = 0.011), 3 (southwest; p = 0.024), 4 (east central; p = 0.012), 6 (northern Lower Peninsula; p = 0.008), and 8 (Upper Peninsula; p < 0.001) all had statistically significant greater variance in annual rates of operation compared with region 1. Region 8 had the largest variance and was the most rural and furthest from region 1. The variance in operation rate between urban and rural differed significantly (p = 0.005).ConclusionsA significant increase in variation of care was found in rural vs urban counties, as well as in regions distant to larger hospital systems. Those of male sex, White race, rural residence, and those with health insurance were significantly more likely to receive operation.Copyright © 2023 by the American College of Surgeons.
