Informed consent for cardiac procedures: deficiencies in patient comprehension with current methods

Area of Science:

• Cardiology
• Medical Education
• Informed Consent

Background:

• Patients often lack understanding of cardiac catheterization/PCI risks, benefits, and alternatives.
• Effective preprocedural education is crucial for informed consent.

Purpose of the Study:

• To compare the effectiveness of two preprocedural educational methods.
• To enhance patient knowledge of informed consent elements for cardiac procedures.

Main Methods:

• Pilot study comparing scripted verbal/written consent (Group I) vs. web-based audiovisual presentation (Group II).
• Random assignment of patients undergoing first-time elective cardiac catheterization/PCI.
• Pre- and post-questionnaires assessed patient understanding of consent elements.

Main Results:

• Both methods improved comprehension of risks and benefits.
• Web-based education (Group II) showed significantly greater improvement in identifying treatment alternatives.
• Despite improvements, patient misperceptions regarding PCI benefits persisted.

Conclusions:

• Both consent approaches enhance patient understanding, but challenges remain.
• Web-based education may be more effective for explaining treatment alternatives.
• Further research is needed to improve patient comprehension of medical procedures and outcomes.
