ABSTRACT
BACKGROUND:
Adequate bowel preparation is an important colonoscopy quality indicator. Reinforced education is effective in improving bowel preparation quality of colonoscopy with mixed indications. However, it remains unclear whether such improvement can be consistently observed in pre- and post-irrigation during colonoscopy in screening population.OBJECTIVE:
We aimed to study the effectiveness of nurse-led reinforced education delivered via mobile messenger (WhatsApp Messenger) on pre- and post-irrigation bowel preparation adequacy in colonoscopies for positive fecal immunochemical test in a population-based colorectal cancer screening program.DESIGN:
Randomized controlled trial.SETTING:
A hospital-based endoscopy centre in Hong Kong, China.PARTICIPANTS:
Patients undergoing colonoscopy for positive fecal immunochemical test in a population-based colorectal cancer screening program.METHODS:
The recruited patients were randomized to receive either WhatsApp Reinforced Education (WRE) or No Reinforced Education (NRE) (11). Patients in WRE group received one-off reinforced education of bowel preparation in text and video formats via WhatsApp Messenger four days prior to colonoscopy sent by investigator while NRE group received standard-of-care only. Primary outcome was the bowel preparation adequacy rate as evaluated by Aronchick Scale. Secondary outcomes included bowel preparation adequacy rate as evaluated by Boston Bowel Preparation Scale, adenoma detection rate and risk factors of bowel preparation inadequacy. Continuous variables were described as means with standard deviation (SD) and analyzed with Student's t-test. The Pearson Chi Square Test or Fisher Exact Test was used to assess categorical variables when appropriate. Risk factors were determined by logistic regression.RESULTS:
From July 2017 to April 2019, 685 eligible patients were randomized to WRE (nâ¯=â¯343) and NRE (nâ¯=â¯342) groups. Patients in WRE group had higher bowel preparation adequacy rate as evaluated by Aronchik Scale (83.4% vs 75.4%, pâ¯=â¯0.010) and Boston Bowel Preparation Scale (94.2% vs 88.9%, pâ¯=â¯0.013). Adenoma detection rate was higher in WRE group but without statistical significance (71.4% vs 67.5%, pâ¯=â¯0.27). In logistic regression, WhatsApp Reinforced Education reduced the inadequate bowel preparation risk (Adjusted odds ratio 0.564; 95% confidence interval 0.371-0.856, pâ¯=â¯0.007). Male gender (Adjusted odds ratio [AOR] 1.638; 95% confidence interval [CI] 1.054-2.546, pâ¯=â¯0.028) and diabetes (AOR 2.062; 95% CI 1.215-3.497, pâ¯=â¯0.007) were risk factors of bowel preparation inadequacy.CONCLUSIONS:
Nurse-led mobile messenger-initiated reinforced education improves both pre- and post-irrigation bowel preparation quality of screening colonoscopy following positive fecal immunochemical test. It is readily incorporable in clinical practice because of its low setup cost. REGISTRATION NUMBER Registered on 4 July 2017 on https//clinicaltrials.gov/ (NCT03209739).Key words
