Patient comprehension of an interactive, computer-based information program for cardiac catheterization: a comparison...

Area of Science:

• Cardiology
• Medical Informatics
• Patient Education

Background:

• Standard patient information for medical treatments is often poorly understood.
• Effective communication of complex medical procedures is crucial for informed consent.

Purpose of the Study:

• To evaluate the effectiveness of an interactive computerized information program (ICI) versus standard information (SI) in improving patient understanding of cardiac catheterization.
• To assess the impact of ICI on patient comprehension of procedure risks and treatment options.

Main Methods:

• 135 adult patients undergoing cardiac catheterization were randomized to receive either SI or ICI.
• Patient understanding was assessed via semistructured interviews at baseline, immediately post-procedure, and two weeks later.
• The primary outcome was the change in understanding from baseline to early post-procedure between the two groups.

Main Results:

• The ICI group showed significantly greater improvement in understanding compared to the SI group.
• More patients in the ICI group achieved complete understanding of risks (53.6% vs 23.1%) and treatment options (63.2% vs 46.2%).
• Baseline knowledge, younger age, and use of ICI were predictors of improved understanding.

Conclusions:

• Interactive computerized information programs can enhance patient understanding of cardiac catheterization more effectively than standard methods.
• This technology shows promise for improving patient comprehension of various medical treatments and procedures.
• Digital tools offer a valuable method for delivering clear and understandable medical information to patients.
