ObjectiveAdequate bowel preparation is an essential factor in colonoscopy. Enhanced education on the procedure of bowel preparation is very necessary for patients before colonoscopy. We analysed the influence of a novel education platform on bowel preparation quality before colonoscopy.Patients And MethodsThe study enrolled outpatients who underwent colonoscopy in the digestive endoscopy centre of Wuhan Tongji Hospital. They were divided into the control group and the intervention group according to different educational ways. The control group patients were provided with the regular colonoscopy preparation leaflet. The intervention group patients were asked to add the education platform. The primary outcome was the rate of adequate bowel preparation. The study was registered at Chinese ClinicalTrials.gov (ChiCTR2100053547, 24/11/2021).ResultsA total of 378 patients who underwent colonoscopy were enrolled, including 189 patients in the control group and 189 patients in the intervention group. The Boston bowel preparation score (BBPS) was significantly higher in the intervention group than that in the control group (p < .05). The adequate rate of bowel preparation in the intervention group was significantly improved than that in the control group (p = .000). Compared with the control group, the polyp detection rate (PDR) was significantly higher in the intervention group (p = .006), especially in the left colonic (p = .006). Among constipation patients, the adequate rate of bowel preparation (p = .000) and the PDR (p = .004) were significantly improved than that in the control group.ConclusionsThe smartphone education platform may effectively improve bowel preparation quality, PDR, and patients' compliance.Key messagesThe quality of bowel preparation mainly relies on the patients' compliance with the bowel preparation instructions.The study reveals that the superiority of the smartphone education platform by Mini Program in improving bowel preparation and colorectal polyp detection rate.The smartphone education platform may provide a more effective, convenient, and labour-saving way to provide further improvements to patients prior to colonoscopy.
