Patients\u27 attitudes and perceptions of implantable cardioverter-defibrillators: potential barriers to appropriate primary prophylaxis

BACKGROUND: Primary prophylaxis with implantable cardioverter-defibrillators (ICDs) improves mortality in patients at risk for sudden cardiac death (SCD). However, ICDs are highly underutilized. We explored patients\u27 attitudes and perceptions of ICDs to better understand potential patient-related barriers to appropriate utilization. METHODS: Records of patients visiting three outpatient cardiology clinics (June 2009-January 2010) were reviewed and 133 with ejection fraction

Perceptions of Benefit and Risk of Patients Undergoing First-time Elective Percutaneous Coronary Revascularization

OBJECTIVE: To assess reasons why patients undergo elective percutaneous coronary revascularization (PCR), patient expectations of the benefits of PCR, and their understanding of the risks associated with PCR. We hypothesized that patients overestimate the benefits and underestimate the risks associated with PCR. DESIGN: A prospective, semistructured questionnaire. PARTICIPANTS: Patients undergoing their first elective PCR. MAIN RESULTS: Fifty-two consecutive patients with a mean age of 64.3 years (range 39-87) completed the interview. Although 30 (57%) patients cited relief of symptoms as at least 1 reason to have PCR, 32 (62%) patients cited either an abnormal diagnostic test result (i.e., exercise stress test or catheterization) or “pathophysiologic” problem (i.e., “I have a blockage”), with 17 patients (33%) citing these reasons alone as indications for PCR. Thirty-nine (75%) patients believed PCR would prevent a future myocardial infarction, and 37 (71%) patients felt PCR would prolong their life. Regarding the potential complications, only 24 patients (46%) could recall at least 1 possible complication. However, on a Deber questionnaire, the majority of patients (67%) stated that they should determine either mostly alone or equally with a physician how acceptable the risks of the procedure are for themselves. CONCLUSIONS: The majority of patients had unrealistic expectatations about the long-term benefits of elective PCR and was not aware of the potential risks, even though they expressed a strong interest in participating in the decision to have PCR. More work is needed to define the optimal strategy to educate patients about the benefits and risks of elective PCR, and whether such education will affect patient decision making
