title: Disease-specific outcomes assessment for diagnosis of colorectal neoplasia: from clinical trials to community practice.
abstract: The value of monitoring the performance of diagnostic testing in clinical practice is emphasized through data showing that experts with apparently equal training have substantially different sensitivity for cancer and polyp detection when performing colonic imaging studies. The authors discuss the effects of variation in study population, testing methodology, and expertise of examiners on the outcomes of diagnostic tests for colorectal cancer.
