Summary
This summary is machine-generated.

A mobile app did not significantly improve bowel preparation adherence or quality compared to paper instructions. However, the app was user-friendly and well-accepted by patients for colonoscopy preparation.

Area of Science:

  • Gastroenterology
  • Medical Informatics
  • Health Technology Assessment

Background:

  • Effective bowel preparation is crucial for successful colonoscopy.
  • Adherence to dietary restrictions and purgative regimens is essential for optimal bowel cleansing.
  • Traditional paper-based instructions may have limitations in patient engagement and adherence.

Purpose of the Study:

  • To evaluate the impact of a customized mobile application (App) on patient adherence to bowel preparation instructions.
  • To assess the effect of the App on the quality of bowel preparation for elective colonoscopy.
  • To compare the user-friendliness and acceptance of App-based versus paper-based instructions.

Main Methods:

  • A randomized controlled trial involving 160 patients undergoing elective colonoscopy.
  • Patients were assigned to receive either paper or App-based instructions for a low-fiber diet, clear fluids, and split-dose sodium picosulfate/magnesium citrate (SPS).
  • Adherence, bowel preparation quality (Aronchick, Ottawa, Chicago scales), and patient feedback were assessed. Colonoscopists were blinded to the intervention group.

Main Results:

  • No statistically significant differences were found in overall adherence or bowel preparation quality between the App and paper instruction groups.
  • Adherence rates were 82.4% for the App group and 73.4% for the control group (P=0.40).
  • The mobile application was rated as more user-friendly than paper instructions (P<0.01), and patients with a BMI < 30 showed better compliance with the clear fluid diet.

Conclusions:

  • Sodium picosulfate/magnesium citrate (SPS) is an effective and well-tolerated bowel preparation agent.
  • Customized mobile applications are a viable, well-accepted alternative to paper instructions for bowel preparation.
  • While not improving adherence or quality in this study, the App demonstrated user preference and potential for future optimization.
