BACKGROUND: The creation of no interruption zones (NIZs) reduces medical errors by reducing distraction levels on hospital wards. To date, the effect of a NIZ during colonoscopy has not been evaluated. AIMS: Assess the effects of a NIZ during colonoscopy, on distraction levels, withdrawal times, and adenoma detection rates (ADRs). METHODS: This was a non-randomized prospective study of screening colonoscopies at a teaching hospital. The intervention, a NIZ, was created by limiting conversations to the care of the patient undergoing the procedure and posting a "do not disturb" sign during the withdrawal phase of colonoscopy. Distraction levels, withdrawal times, and ADRs were analyzed at baseline and after the NIZ. RESULTS: The implementation of the NIZ leads to a significant reduction of high-distraction-level environments (13.1 vs. 5.1 %; p < 0.0001). There was a significant decrease in withdrawal time with NIZs; (10.6 vs. 9.9 min, p = 0.0038). There was no significant difference in ADRs (38 % baseline vs. 36 % NIZs, respectively; p = 0.33). CONCLUSIONS: Creation of a NIZ was associated with a significant decrease in high-distraction environments and shorter withdrawal times with no significant change in ADRs. Further studies are needed to evaluate whether lower distraction levels in an endoscopy suite translate to improved quality measures.
