WebFIT is positive in 9-10% of screening aged patients, and this positivity rate increases to 15-20% if the lower positivity threshold is used. The current algorithm is to perform colonoscopy in those who are positive. Only <1% of screening aged patients have colon cancer. At a 10% positivity rate that the false positive rate of the FIT is >9%.

WebBackground: Colorectal cancer screening by fecal immunochemical tests (FITs) is hampered by frequent false-positive (FP) results and thereby the risk of complications and strain on colonoscopy capacity. Hemorrhoids might be a plausible cause of FP results. Objective: To determine the contribution of hemorrhoids to the frequency of FP FIT results. WebIn this study, chi-square-based fit indices (i.e., Yen's Q[subscript 1], McKinley and Mill's G[superscript 2], Orlando and Thissen's S-X[superscript 2], and S-G[superscript 2]) were extended to HO-IRT models. Their performances are evaluated via simulation studies in terms of false positive rates and correct detection rates.
