Evaluating informed consent for colonoscopy.

Area of Science:

• Gastroenterology
• Medical Communication
• Patient Education

Background:

• Assessing patient knowledge and information preferences for colonoscopy is crucial for effective healthcare communication.
• Understanding patient demographics and their correlation with information needs can optimize patient education strategies.

Purpose of the Study:

• To evaluate patient knowledge of colonoscopy procedures and their preferences for information delivery.
• To identify how patients best understand procedural risks and correlate this with demographic factors.

Main Methods:

• A voluntary questionnaire was administered to colonoscopy patients at St Vincent's Public Hospital.
• Data collected included patient demographics, perceived knowledge of colonoscopy, and preferred communication formats for procedural information and risk explanation.

Main Results:

• Patient-perceived knowledge of colonoscopy was significantly lower than their preferred levels.
• Higher education levels correlated with a preference for written information (leaflets), while lower education levels preferred verbal communication.
• Pie graphs were the most preferred format for explaining perforation risk, followed by pictographs and absolute risk ratios.

Conclusions:

• Patients receive suboptimal information regarding colonoscopy, particularly concerning procedural risks.
• A multi-modal approach combining written materials, visual aids (graphs, diagrams), and verbal discussion is recommended for effective patient understanding.
• Further research with larger patient cohorts is needed to enhance informed consent processes in colonoscopy.
