Do patients want to be informed? A study of consent for cardiac catheterisation

Area of Science:

• Cardiology
• Medical Ethics
• Patient Communication

Background:

• Informed consent is a cornerstone of medical ethics.
• Cardiac catheterization carries inherent risks that necessitate thorough patient understanding.
• Assessing patient recall of pre-procedure information is crucial for evaluating consent processes.

Purpose of the Study:

• To evaluate patient recall of information provided before cardiac catheterization.
• To determine the extent to which patients understood the risks associated with the procedure.
• To explore patient preferences regarding the disclosure of risks and complications.

Main Methods:

• A survey was conducted with 104 patients who had undergone cardiac catheterization.
• Patients were asked to recall information received prior to giving consent.
• Data collected included details about explanations of the procedure, warnings of symptoms, and awareness of potential complications, including death.

Main Results:

• 14% of patients received no explanation prior to the procedure.
• 24% were not warned about specific symptoms or side effects.
• 40% were informed about possible complications, and 26% were warned of the risk of death.
• A significant majority of patients did not fully comprehend the risks.
• Two-thirds of patients indicated they would not have wanted to be informed about these risks.

Conclusions:

• Current practices for obtaining informed consent for cardiac catheterization may be inadequate in fully informing patients.
• Patient preferences for information disclosure vary, with many preferring less detail about risks.
• Physicians should tailor the depth of information provided based on individual patient anxiety levels and inquiry.
• Balancing the need for informed consent with patient psychological well-being is essential.
