The Value of Audio Devices in the Endoscopy Room (VADER) study: a randomised controlled trial

Objective: To evaluate the effect of Star Wars music (SWM) compared with endoscopist-selected popular music (PM) on quality outcomes in colonoscopy. Design and setting: A single-centre, prospective, randomised controlled trial conducted in an endoscopy suite within a quaternary-centre gastroenterology unit, Melbourne, Australia. Main outcome measures: The primary outcome measures were procedure time, polyp detection rate (PDR) and adenoma detection rate (ADR). The secondary outcome measure was adenomas per colonoscopy (APC). Results: 103 colonoscopies were analysed: 58 in the SWM group and 45 in the PM group. Bowel preparation was assessed as good or excellent in 57% of the SWM group compared with 69% of the PM group (P < 0.01). The PDR was significantly higher in the SWM group than in the PM group (60% v 35%; P = 0.006). Similarly, the ADR was significantly higher in the SWM group than in the PM group (48% v 27%; P = 0.01). The APC in the SWM group was 84% compared with 35% in the PM group (P = 0.01). Conclusion: SWM compared with PM improves key quality outcomes in colonoscopy, despite poorer bowel preparation.
