ABSTRACT
BACKGROUND: Implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-D) are lifesaving treatments for patients at risk for sudden cardiac death. Effective physician-patient communication during the shared decision-making process is essential. Electrophysiologist-patient conversations were targeted to obtain objective data on the interaction, understand the conversation framework, and uncover opportunities for improved communication. METHODS: Individuals previously identified as requiring an ICD/CRT-D but declined implantation were recruited for this four-stage interview and survey-based study. Quantitative analysis of surveys and AI analysis of conversation videos was conducted to evaluate patient participant expectations, analyze feedback about the conversations with study physicians, and gauge willingness for device implantation. RESULTS: The study included 27 patients (mean age 51 years, 51.9% female) and 9 study physicians. Patients were significantly more willing to undergo ICD/CRT-D implantation after conversing with study physicians compared to their own physicians and pre-conversation surveys (mean scores: 5.0, 3.1, and 4.4 out of 7, respectively; p < 0.001). Patient participants had higher satisfaction with the study conversation, rating study physicians higher in effectiveness of explanations, responsiveness to questions, and overall quality of the conversation compared to their own physicians (all p < 0.001). CONCLUSIONS: In a cohort of patients who previously declined ICD/CRT-D implantation, patient satisfaction and willingness to undergo implantation of a guideline-directed device therapy increased significantly following a structured conversation with study physicians. Identified key elements could be integrated into user-friendly tools and educational materials to facilitate these conversations, improving patient engagement with the decision-making process and enhancing informed acceptance of indicated device therapies.
ABSTRACT
BACKGROUND: Despite data showing the benefits of implantable cardioverter-defibrillator (ICD) insertion for primary prevention in populations at risk for sudden death, professional society guidelines recommending primary prevention, and recognition by payers of the clinical value of ICDs in these populations, ICDs for primary prevention remain underused. We sought to determine whether implementing a screening tool would increase appropriate identification of patients showing clinical evidence of ICD benefit and prompt referral to an electrophysiologist for ICD implantation. METHODS AND RESULTS: Screening tools were affixed to medical records for patients seen in 2 outpatient cardiology offices that queried ejection fraction and whether referral to an electrophysiologist was made (N=6632). The number of appropriate referrals in the screening period were compared with analogous data collected before implementation of the screening tool (control period) through retrospective record review (n=3606). Significantly more eligible patients were offered referral during the screening period than during the control period at both sites, 80% (8/10 eligible) versus 33% (5/15) at site 1 (P<0.02) and 100% (44/44) versus 60% (21/35) at site 2 (P<0.001). Of all patients offered referral, 41% (32/78) accepted. CONCLUSIONS: The use of a screening tool increases referral to electrophysiology for patients in whom placement of an ICD confers the benefit of sudden cardiac death primary prevention. Barriers to referral include both physician and patient factors. Verification of these findings on a larger scale as well as studies defining the foundation of these barriers may further improve use of ICDs in patients for whom their mortality benefit is well described.
