Pdf Summary

This presentation by Dr. Aasma Shaukat from NYU Langone Health emphasizes the critical importance of quality in colorectal cancer (CRC) screening programs, focusing on stool-based tests and colonoscopy quality indicators.<br /><br />For stool-based screening, especially fecal immunochemical tests (FIT), establishing clear protocols for sample handling and patient education is vital. Key quality indicators include high completion rates (>60%), low rates (<5%) of unprocessable tests, and colonoscopy completion (>80%) following positive FIT results. The US Multi-Society Task Force (USMSTF) recommends single-sample FIT over guaiac-based tests due to better adherence and stresses repeated annual testing and timely colonoscopy follow-up to prevent CRC.<br /><br />Colonoscopy quality indicators are well-defined and evolving. Important metrics include cecal intubation rates (≥90%), adequate bowel prep (≥85-90%), adenoma detection rate (ADR) benchmarks (35-45% depending on indication and age), sessile serrated lesion detection rate (~6%), withdrawal time (8-9 minutes), polyp resection documentation (≥98%), and adherence to surveillance guidelines (≥90%). Higher ADR is linked to reduced risk of post-colonoscopy CRC and death.<br /><br />Challenges include poor follow-up after abnormal stool tests (24-55% completion rates) and incomplete polyp resection, which increases future neoplasia risk. Techniques such as rigorous withdrawal inspection, proper resection methods (cold snare for 4-9mm polyps), and advanced technologies like computer-aided detection (CADe) can improve outcomes. Multifaceted interventions combining education, technique, and technology are recommended.<br /><br />Quality programs should involve continuous monitoring, report cards for endoscopists, and public transparency. The evolving landscape requires GI physicians to engage in patient education, ensure high-quality exams, advocate for access, and collaborate with PCPs and payors.<br /><br />In summary, quality in CRC screening is a continuum demanding rigorous, systematic measurement and improvement of stool-based tests and colonoscopy practices to reduce CRC incidence and mortality effectively.
