Disparities in guideline-compliant care for patients with pancreatic ductal adenocarcinoma at minority-versus non-minority-serving hospitals

Background: We examined disparities in guideline-compliant care at minority-serving hospitals (MSH) versus non-MSH among patients with localized or metastatic pancreatic adenocarcinoma (PDAC). Methods: Patients with PDAC were identified within the National Cancer Database (2004-2018). Guideline-compliant care was defined as surgery + chemotherapy +/- radiation therapy for localized and chemotherapy for metastatic disease. Facilities in the top decile of minority patients treated were considered MSH.Results: A total of 190,950 patients were identified and most (59.6%) had metastatic disease. Overall, 6.4% of patients with localized and 8.2% of patients with metastatic disease were treated at MSH. Patients treated at MSH were less likely to receive guideline-compliant care (localized: OR = 0.78, 95% CI: 0.67-0.91; metastatic: OR = 0.77, 95% CI: 0.67-0.88). Minority patients were less likely to receive guideline-compliant care at non-MSH (localized: OR = 0.71, 95% CI: 0.67-0.75; metastatic: OR = 0.85, 95% CI: 0.82-0.89) or MSH (localized: OR = 0.85, 95% CI: 0.74-0.98; metastatic: OR = 0.91, 95% CI: 0.82-0.99). Patients treated at non-MSH or MSH who received guideline-compliant care were more likely to have higher OS regardless of stage or race.Conclusions: MSH patients were less likely to receive guideline-compliant care and minority patients were less likely to receive guideline-compliant care regardless of MSH status. Guideline-compliant care was associated with improved OS.
