Factors Associated with Surveillance Adenoma and Sessile Serrated Polyp Detection Rates.
Digestive Diseases and Sciences 2017 December
BACKGROUND: Adenoma detection rate (ADR) and sessile serrated polyp detection rate (SSPDR) data in surveillance colonoscopy are limited.
AIMS: Our aim was to determine surveillance ADR and SSPDR and identify associated predictors.
METHODS: A retrospective review of subjects who underwent surveillance colonoscopy for adenoma and/or SSP at an academic center was performed. The following exclusion criteria were applied: prior colonoscopy ≤ 3 years, incomplete examination, or another indication for colonoscopy. Patient, endoscopist, and procedure characteristics were collected. Predictors were identified using multivariable logistic regression.
RESULTS: Of 3807 colonoscopies, 2416 met inclusion criteria. Surveillance ADR was 49% and, SSPDR was 8%. Higher ADR was associated with: age per year (OR 1.03; 95% CI 1.02-1.04), male gender (OR 1.55; 95% CI 1.29-1.88), BMI per kg/m2 (OR 1.02; 95% CI 1.01-1.04), withdrawal time per minute (OR 1.09; 95% CI 1.07-1.10), and endoscopists' screening ADR (OR 1.01; 95% CI 1.00-1.03). Years since training (OR 0.99; 95% CI 0.98-0.99) was associated with lower ADR. Family history of CRC (OR 1.58; 95% CI 1.02-2.27) and endoscopists' screening ADR (OR 1.40; 95% CI 1.15-1.74) were associated with higher SSPDR. African-American race (OR 0.36; 95% CI 0.10-0.75) and diabetes (OR 0.41; 95% CI 0.21-0.76) were associated with lower SSPDR.
CONCLUSIONS: For surveillance colonoscopy, nearly half of patients had an adenoma and one in twelve had an SSP. In addition to established factors, BMI, endoscopists' screening ADR, and years since training were associated with ADR, whereas African-American race and diabetes were inversely associated with SSPDR. Further studies are needed prior to integrating surveillance ADR and SSPDR into quality metrics.
