A randomized, controlled trial of interactive, multimedia software for patient colonoscopy education

Area of Science:

• Medical Education
• Gastroenterology
• Health Informatics

Background:

• Patient education is crucial for colonoscopy preparation and outcomes.
• Traditional methods may have limitations in ensuring comprehensive understanding.
• Computer-assisted instruction (CAI) offers a potential enhancement to standard educational approaches.

Purpose of the Study:

• To evaluate the effectiveness of CAI compared to standard education for patients undergoing colonoscopies.
• To assess the impact of CAI on patient anxiety, comprehension, and satisfaction.

Main Methods:

• A randomized controlled trial was conducted in a multispecialty clinic.
• Eighty-six patients were allocated to either standard education or standard education plus CAI.
• Outcomes measured included anxiety, comprehension of procedure details, and satisfaction with information provided.

Main Results:

• CAI did not significantly reduce patient anxiety.
• Patients receiving CAI demonstrated significantly better overall comprehension (p < 0.001).
• Satisfaction with the amount of information was higher in the CAI group (p = 0.001), though overall satisfaction was unaffected.

Conclusions:

• Computer-assisted instruction enhances patient comprehension and satisfaction with information adequacy for colonoscopy.
• CAI can be integrated into practice to improve patient education without negatively impacting the patient-physician relationship.
• Targeted educational components, such as serious complications and postsedation behavior, require further optimization within CAI modules.
