Physicians' judgments of the risks of cardiac procedures. Differences between cardiologists and other internists

Area of Science:

• Cardiology
• Medical Decision Making
• Health Services Research

Background:

• Physicians' risk perception of invasive cardiac procedures is crucial for patient care and resource allocation.
• Existing literature suggests potential discrepancies in risk assessment between specialists and generalists.

Purpose of the Study:

• To compare the population risk judgments of invasive cardiac procedures between cardiologists and other internal medicine physicians.
• To evaluate the accuracy of these risk judgments.

Main Methods:

• A cross-sectional survey was conducted across US and UK teaching hospitals and a US community hospital.
• Participants included senior staff and trainees in internal medicine and cardiology.
• Risk judgments for severe morbidity and death from four procedures (Swan-Ganz catheterization, cardiac catheterization, percutaneous coronary angioplasty, coronary artery bypass grafting) were assessed.

Main Results:

• Cardiologists judged the risks of severe morbidity and death to be significantly lower than did other internists for most procedures.
• Cardiologists demonstrated higher accuracy in judging morbidity and death rates for cardiac catheterization.
• Other internists were more accurate in judging morbidity rates for Swan-Ganz catheterization.

Conclusions:

• Significant differences exist in the perception of population risks for invasive cardiac procedures between cardiologists and other internists.
• Discrepancies in risk assessment may stem from limited or conflicting published data.
• Further research is needed to clarify data presentation and improve risk communication.
