Computer-based tutorial to enhance the quality and efficiency of the informed-consent process for cataract surgery

Area of Science:

• Ophthalmology
• Medical Education
• Health Informatics

Background:

• Informed consent is crucial for patient autonomy in medical procedures.
• Traditional informed consent may not always ensure adequate patient comprehension.
• Cataract surgery requires informed consent regarding risks, benefits, and alternatives.

Purpose of the Study:

• To evaluate if an interactive computer-based tool enhances patient understanding during informed consent for cataract surgery.
• To compare the effectiveness of a digital tool plus physician discussion versus conventional physician-led consent.

Main Methods:

• A randomized controlled trial involving patients scheduled for bilateral cataract surgery.
• Patients were allocated to either an intervention group (computer tool + discussion) or a control group (sham presentation + discussion).
• The interactive tool (CatInfo) provided audiovisual information on cataract and treatment; questionnaires assessed comprehension.

Main Results:

• The intervention group demonstrated statistically significant higher correct answers on post-consent questionnaires (15/19 vs. 12/19).
• The computer-based tool was particularly beneficial for older patients.
• A total of 90 patients participated (60 in the study group, 30 in the control group).

Conclusions:

• Interactive computer-based tools significantly improve patient understanding in the informed consent process for cataract surgery.
• This digital tutorial enhances the effectiveness of conventional informed consent procedures.
• The findings support the use of technology to improve patient education and decision-making.
