简要总结
A retrospective and prospective study to determine if the use of ambient lighting during screening colonoscopy is well tolerated and if ambient lighting will help physicians maintain adenoma detection rates while decreasing symptoms of eye strain as the day progresses.
详细描述
This study is a a single-center study at an independent community-based teaching hospital comparing adenoma detection rate in screening colonoscopies performed in low lighting with those performed with ambient lighting (75-150 lux). All cases included in the study involved adult patients undergoing screening colonoscopy with a participating gastroenterologist. Diagnostic colonoscopies, history of colon resection, colorectal cancer, and cases performed in children, pregnant women, and prisoners were excluded from analysis. Cases involving gastroenterology fellows were also excluded. Retrospective data was collected over a six month period from January 2017 to June 2017, followed by a prospective arm the during the same calendar months the subsequent year (January 2018 to June 2018).

结局指标
主要结局
Change in adenoma detection rate
时间窗: 6 months
Adenoma detection rate, comparing change from first case of the day to the last. Ranges from 0-99%, with greater increases adenoma detection rate (ADR) being more favorable.
Eye strain score
时间窗: 6 months
Eye strain score, as calculated from survey responses completed by physicians. Ranges from 0 - 60, with lower scores indicating less severe symptoms (therefore, lower scores are more favorable).
次要结局
- Adenoma detection rate (overall)(Participants each assessed on one day during 6 month study period)
- Satisfaction by staff(6 months)
- Adenoma detection rate (first case vs last case of the day)(Participants each assessed on one day during 6 month study period)
