Impact of Video Aid on Quality of Bowel Preparation Among Patients Undergoing Outpatient Screening Colonoscopy

To investigate the effect of video aid on quality of bowel preparation.

A retrospective study was done on patients undergoing outpatient screening colonoscopy. All subjects received educational video prior to colonoscopy in addition to the standard counseling. Patient charts were reviewed to collect data regarding quality of bowel preparation (adequate or inadequate). The study population was stratified into four groups according to viewing status: Group I 0% (control group), Group II <50%, Group III >50% to <75%, and Group IV watched ⩾75% of the video.

A total of 338 patients with an average age of 59.1 years and 60.3% females were included in the final study cohort. Of the patients in Groups I, II, III, and IV, 94.3%, 90.9%, 100%, and 91.7%, respectively, had adequate preparation (P value = .827). Adenoma detection rate (ADR) for Groups I, II, III, and IV was 28.8%, 50%, 50%, and 22.6%, respectively (P value = .305). The mean cecal intubation time was 20.7, 16.4, 16.57, and 17 minutes for Groups I, II, III, and IV, respectively (P value = .041).

Video aid use for patients undergoing screening colonoscopy lacked a statistically significant impact on the quality of bowel preparation, ADR, and advanced adenoma detection rate when compared with standard practice.
