Root‐cause analyses of missed opportunities for the diagnosis of colorectal cancer in patients with inflammatory bowel disease

Summary Background Colonoscopic surveillance in patients with inflammatory bowel disease (IBD) leads to earlier detection of colorectal cancer (CRC) and reduces CRC‐associated mortality. However, it is limited by poor adherence in practice. Aim To identify missed opportunities to detect IBD‐associated CRC at our hospital Methods We undertook root‐cause analyses to identify patients with missed opportunities to diagnose IBD‐associated CRC. We matched patients with IBD‐associated CRC to patients with CRC in the general population to identify differences in staging at diagnosis and clinical outcomes. Results Compared with the general population, patients with IBD were at increased risk of developing CRC (odds ratio 2.7 [95% CI 1.6‐3.9], P
