Timeline of EP and example scenario with dates. Arrows indicate prespecified intervals used by the digital quality measure and chart reviewers. If a cancer signal is present before EP, reviewers allow 7 days to order follow-up testing and 30 days (for lung cancer) to complete follow-up. Using the dates of the example scenario, follow-up was not ordered at the time of the first cancer signal, which would be judged as a missed opportunity for diagnosis. CRC, colorectal cancer; CT, computed tomography; EP, emergency presentation; FIT, fecal immunochemical test; FOBT, fecal occult blood test; MOD, missed opportunity for diagnosis; PET, positron emission tomography.
