Background: Studies thus far lacking diversity show many patients with implantable cardioverter defibrillators (ICDs) have poor understanding of ICD functioning, preventing informed decision-making near end of life (EOL).
Objective: To describe knowledge, perceptions, and preferences regarding ICDs among patients nearing EOL in a diverse, safety-net hospital population.
Methods: A cross sectional phone survey of patients with ICDs nearing EOL from a safety-net hospital was performed. The survey assessed knowledge, perceptions, and preferences regarding their ICD.
Results: Nearly half (46%) of patients falsely believed turning off shocking function would stop the heart, 69% were unaware that disabling ICDs does not require surgery, and 88% said no doctor had ever discussed the option of deactivation of shocking therapy with them.
Conclusion: Challenges in health care delivery in a safety-net hospital patient population may result in patients being poorly equipped to align ICD settings with goals of care when nearing EOL.
