Hypothesis
Can a web-based tool enhance the informed consent process for patients undergoing coronary angiography?
Conclusion
The implementation of the PREDICT tool improved patient understanding and engagement in the informed consent process.
Supporting Evidence
- 72% of patients using PREDICT read the consent form compared to 44% with the original form.
- 65% of PREDICT patients reported feeling not nervous at all after reading the consent form.
- 67% of PREDICT patients felt involved in the decision-making process.
Takeaway
Doctors used a new tool to help patients understand the risks of heart procedures better, making it easier for them to ask questions and feel involved.
Methodology
A web-based tool was created to generate personalized consent documents with patient-specific risk estimates, followed by qualitative and quantitative evaluations of its implementation.
Potential Biases
Potential bias due to the involvement of developers in the evaluation process.
Limitations
The evaluation was conducted by the developers of the tool, which may introduce bias.
Participant Demographics
Patients undergoing coronary angiography at four hospitals in Kansas City.
