Abstract
INTRODUCTION: Residential racial desegregation has demonstrated improved economic and education outcomes. The degree of racial community segregation relative to surgical outcomes has not been examined. PATIENTS AND METHODS: Patients undergoing pancreatic resection between 2013 and 2017 were identified from Medicare Standard Analytic Files. A diversity index for each county was calculated from the American Community Survey. Multivariable mixed-effects logistic regression with a random effect for hospital was used to measure the association of the diversity index level with textbook outcome (TO). RESULTS: Among the 24,298 Medicare beneficiaries who underwent a pancreatic resection, most patients were male (n = 12,784, 52.6%), White (n = 21,616, 89%), and had a median age of 72 (68-77) years. The overall incidence of TO following pancreatic surgery was 43.3%. On multivariable analysis, patients who resided in low-diversity areas had 16% lower odds of experiencing a TO following pancreatic resection compared with patients from high-diversity communities (OR 0.84, 95% CI 0.72-0.98). Compared with patients who resided in the high-diversity areas, individuals who lived in low-diversity areas had higher odds of 90-day readmission (OR 1.16, 95% CI 1.03-1.31) and had higher odds of dying within 90 days (OR 1.85, 95% CI 1.45-2.38) (both p < 0.05). Nonminority patients who resided in low-diversity areas also had a 14% decreased likelihood to achieve a TO after pancreatic resection compared with nonminority patients in high-diversity areas (OR 0.86, 95% CI 0.73-1.00). CONCLUSION: Patients residing in the lowest racial/ethnic integrated counties were considerably less likely to have an optimal TO following pancreatic resection compared with patients who resided in the highest racially integrated counties.
