Real-world compliance with the 2020 U.S. Multi-Society Task Force on Colorectal Cancer polypectomy surveillance guidelines: an observational study.

ABSTRACT

BACKGROUND AND AIMS: Overuse of screening colonoscopy increases cost and procedural adverse events, but inadequate surveillance can miss the development of colorectal cancer. We measured compliance with the 2020 U.S. Multi-Society Task Force on Colorectal Cancer (USMSTF) polypectomy surveillance guidelines in clinical records and a survey. METHODS: We performed a retrospective study comparing surveillance intervals for first-time average-risk colonoscopies with the 2020 USMSTF guidelines. Cases were analyzed from 3 intervals (March 2021 to May 2021, November 2021 to January 2022, and April 2022 to May 2022), collectively termed the postguideline period, and a baseline period from November 2019 to January 2020. Real-world compliance rates were compared with results of a survey conducted between November 2020 and February 2021. RESULTS: Overall compliance was 48.9% among 532 colonoscopies, ranging from 8.3% for low-risk adenomas (LRAs), 88.3% for high-risk adenomas, 63.1% for sessile serrated polyps (SSPs), and 88.6% for hyperplastic polyps. Compliance for LRA increased from the baseline period (.8% vs 8.3%, P = .003), and 95.3% of nonadherent LRA cases followed the 2012 USMSTF guidelines. Compliance for LRAs was 18.6% among respondents who provided a compliant surveillance interval for LRAs in the survey. Noncompliance was associated with finishing training >10 years ago (odds ratio, 1.9; 95% confidence interval, 1.4-2.7) and performing over 800 colonoscopies annually (odds ratio, 2.0; 95% confidence interval, 1.5-2.6). CONCLUSIONS: Adoption of the 2020 USMSTF surveillance guidelines remains low at 2 years. Further research into outcomes for patients with LRAs and SSPs may increase guideline adoption.
