Prevalence of 'One and Done' Phenomenon in Adenoma Detection Within a Large Community-Based Healthcare System

Adenoma detection rate (ADR) is a key quality metric in colonoscopy, reflecting the ability to detect adenomas. However, concerns remain regarding the robustness of ADR as a benchmark. In particular, "one and done" phenomenon may exists where physicians are less motivated to find additional adenoma following the first adenoma. To investigate this further, we aim to understand the relationship between single and multiple adenoma detection.
