Su1349 Impact of Sleep Deprivation on Colonoscopy Performance Among Trainees

Abstract

indication of CRC screening or surveillance, ADR is calculated by the percent of patients with at least one adenoma. Limited Descriptive statistics were calculated. Student’s t-test and analysis of variance was utilized to assess for ADR differences across physician gender and time in practice. The primary end point (change in ADR rate) was assessed across the 12 months of follow-up by using general linear models for repeated measures. The model was adjusted for endoscopist gender and time in practice. Results: 45 GIs were identified. After exclusion criteria, 28 GIs met criteria. 64.3% of GIs were male. 50% were in practice 10 years, 32% were in practice 5-10 years and 18% were in practice 5 years. Mean number of surveillance/screening colonoscopies per 6 month period were 109 (65.1), 106 (67.7), and 118 (64). The mean baseline ADR was 31.1% (8.47). At both 6 and 12 months, the mean ADR increased, respectively [31.5% (8.5),34.6% (7.3)]. By endoscopist gender, mean ADR at baseline (28.8 vs. 32.3), at 6 months (31.1 vs. 31.7) and 12 months (33.3 vs. 35.4) was lower for female endoscopists compared to male endoscopists, although not statistically significant (all p values 0.05). By endoscopists’ time in practice, only the ADR at 12 months was statistically significant, with those in practice 5 yrs with the highest ADR compared to 5-10 years and 10 years respectively. (40.3% vs. 37.0% vs. 31.1% p 0.02). Over 12 months, mean ADR rate increased (estimate 3.5679; S.E. 1.27, p 0.007) and this remained significant at 12 months after adjusting for endoscopist gender and time in practice. Conclusion: Audits sent semi-annually may positively impact GIs’ adenoma detection rate. Assessing optimal frequency for audits may be in order. Additionally, lower ADR rates were seen among female endoscopists. Further investigation into patient gender mix may account for this difference.
