Characteristics of Clinicians Are Associated With Their Beliefs About ICD Deactivation: Insight From the DECIDE-HF Study

Abstract

Background Discussing goals of care with heart failure patients is recommended but is not done systematically, due to factors such as time and personal beliefs. A recent survey showed that one-fifth of clinicians believe that implantable cardioverter defibrillator deactivation (ICDD) is unethical or constitutes physician-assisted suicide. We investigated whether individuals’ characteristics are associated with these beliefs. Methods The Decision-Making About Goals of Care for Hospitalize d Pati e nts With H eart F ailure (DECIDE-HF) survey was given to healthcare providers at 9 hospitals to assess their perceived barriers to goals-of-care discussions. The association between respondent characteristics and their beliefs was examined using 2 adjusted logistic regression models. Results We included 760 clinicians (459 nurses, 94 fellows, and 207 cardiologists). The responses varied among professions, with the belief that ICDD is unethical considered to be important barrier by nurses (24%), fellows (10%), and staff (7%); P < 0.001). After adjusting for site, spirituality being more important in life (odds ratio [OR]: 2.21; 95% confidence interval [CI]:1.37-3.56; P = 0.001, compared to less important), region of training (Asia [OR: 5.88; 95% CI: 2.12-16.31; P = 0.001] and Middle East [OR: 5.55; 95% CI:1.57-19.63; P = 0.008] compared to Canada), and years in practice (OR: 1.32; 95% CI: 1.07-1.63; P = 0.01 per decade) influenced beliefs about ICDD being unethical, with similar results for the belief that ICDD represents physician-assisted suicide. Conclusions Sociocultural factors, region of training, and profession influence clinicians’ beliefs about ICDD being unethical and representing physician-assisted suicide. These factors and beliefs must be acknowledged when facing the delicate issue of end-of-life discussion.
