When a doctor tells us that we need surgery, we usually don’t question his or her judgment, especially if the procedure involves a medical device that can help supplement the function of our heart. But a recent article on CNN Health recently reported that 20% of patients who received an implantable cardioverter-defibrillator, or ICD (a device that produces electrical impulses to regulate heartbeats and prevent life-threatening arrhythmias), were not good candidates to receive the device.
A study of more than 111,000 patients who received ICD implants between 2006 and 2009 was conducted by researchers at Duke University. It was discovered that more than 25,000 of those patients did not meet evidence-based criteria for receiving the ICD.
Physicians and surgeons often recommend ICDs for patients who are at high risk for a cardiac arrest or life-threatening arrhythmia, but have not yet suffered from these symptoms. But according to Dr. Robert Michler, chairman of Cardiovascular and Thoracic Surgery at Montefiore-Einstein Heart Center, “Doctors are well-intentioned, but not all doctors should be determining the use of what is a very sophisticated therapy.”
