Percutaneous coronary intervention (PCI) involves a complex informed consent process. Consent is sought simultaneously for a diagnostic angiography and the potential treatments that follow, including PCI, and fosters shared decision making. This process involves several healthcare providers, yet there has been limited data from the United States regarding the patient’s perspective of informed consent for PCI.
To describe U.S. patients’ perception of their PCI informed consent process, and of PCI treatment risks and benefits.
Patients admitted for coronary angiography were approached and if they volunteered for the study, completed a survey on their informed consent experience for PCI following their procedure. The survey asked about purpose of consent, attitudes, risks, benefits, and outcomes of PCI.
There were 82 participants who had undergone PCI, with a mean age of 65 years. Participants included 64 males and 17 females. The majority of participants recognized the key components of choice (88%), risks (94%), and benefits (87%), and 65% of participants were aware of the alternatives for PCI from the informed consent experience. Participants expressed a desire for more information, but also admitted that they had trouble retaining the information. Eighty-nine percent had misconceptions that PCI would prevent a future myocardial infarction. Forty percent of the participants stated that they preferred family to be present during informed consent.
Healthcare providers can improve the informed consent experience by providing clear information, clarifying concerns, and by encouraging family questions and involvement.
