Association of physician adenoma detection rates with postcolonoscopy colorectal cancer

Colonoscopy screening reduces colorectal cancer incidence and deaths, while failing to detect adenomas is associated with an increased risk of postcolonoscopy colorectal cancer (PCCRC), a cancer diagnosed after a colonoscopy in which no cancer was detected. A retrospective cohort study in 43 endoscopy centers of Kaiser Permanente Northern California, Southern California, and Washington (383 physicians) evaluated the association of the adenoma detection rate (ADR) of the physicians in the calender year prior to a patient’s negative colonoscopy (n=852.624) with the risk of PCCRC. The study found that negative colonoscopies by physicians with higher ADR were significantly associated with lower risks of PCCRC across a broad range of ADR values.
