Music seems to be beneficial in multiple clinical areas. Colonoscopy is a stressful event for patients, especially with conscious sedation. Music during colonoscopy has been evaluated in multiple randomized controlled trials (RCTs) with varied results. Even meta-analyses on the subject over the years have yielded inconsistent conclusions. Therefore, we conducted an up-to-date meta-analysis regarding music during colonoscopy.
To assess the effects of music played during colonoscopy on patients’ perspectives and sedation requirements.
Multiple large databases were aggressively searched (November 2018). RCTs comparing music to without music during colonoscopy on adult patients were included. Pooled estimates were calculated for sedative medication doses, total procedure time, and patients’ experience, willingness to repeat procedure, and pain scores using odds ratio (OR) and mean difference (MD) with random effects model.
Eleven studies (n = 988) were included. Music during colonoscopy showed a statistically significant reduction in procedure times (MD: -2.3 min; 95%CI: -4.13 to -0.47; P = 0.01) and patients’ pain (MD: -1.26; 95%CI: -2.28 to -0.24; P = 0.02) while improving patients’ experience (MD: -1.11; 95%CI: -1.7 to -0.53; P < 0.01) as compared to no music. No statistically significant differences were observed between music and no music during colonoscopy for midazolam (MD: -0.4 mg; 95%CI: -0.9 to 0.09; P = 0.11), meperidine (MD: -3.06 mg; 95%CI: -10.79 to 4.67; P = 0.44), or patients’ willingness to repeat the colonoscopy (OR: 3.89; 95%CI: 0.76 to 19.97; P = 0.1).
Music appears to improve overall patient experience while reducing procedure times and patient pain. Therefore, music, being a non-invasive intervention, should be strongly considered during colonoscopy.
Core tip: Music during stressful events has been shown to improve patient experience. Colonoscopy is a stressful event for many patients. Music during colonoscopy has been studied by many randomized controlled trials and meta-analyses with varying results. Therefore, given new studies available for analysis, we performed an updated meta-analysis. This meta-analysis demonstrated that music during colonoscopy reduces patients’ pain while improving patients’ experience and procedure times. With these results and extremely limited adverse effects of music, music should be strongly considered during colonoscopy.
