Expanded National ICD Registry to include lead, pediatric ICD procedural data

A planned expansion of the National Implantable Cardioverter Defibrillator Registry, currently accruing data on nearly 10,000 ICD implantation procedures per month, will be in regular use starting in early 2010.
New information to be recorded in Version 2.0 of the National ICD Registry includes data for atrial, ventricular, defibrillation, left heart and epicardial leads, as well as data for pediatric ICD implantation procedures. The expanded registry will also include a new data collection form that updates and corrects elements of the initial data collection form.
According to statistics cited in the annual registry report, total complications from new ICD implants decreased from 3.78% in 2006 to 3.01% in 2008. Of the patients who received cardiac resynchronization therapy with defibrillator backup, 70% met published national guidelines, as did 79% of patients who received an ICD for primary prevention. Researchers examining the registry data reported that of 161,470 patients receiving ICDs, women were more likely than men to experience any adverse event (4.4% vs. 3.3%, P<.001) or a major adverse event (2.0% vs. 1.1%, P<.001). Results from another study of the registry data suggested that in 111,293 ICD implantations, 71% were performed by electrophysiologists, 22% by non-electrophysiologists, 2% by thoracic surgeons and 5% by other specialists. The researchers also reported a higher risk for procedural complications in patients whose ICDs were implanted by a non-electrophysiologist.
“The National ICD Registry has really been a true success story,” Richard L. Page, MD, a professor of medicine at the University of Washington School of Medicine in Seattle and president of the Heart Rhythm Society, told Cardiology Today. “We see this as an improvement and an important part of our ongoing commitment to providing quality care that can indeed be measured and demonstrated to be of high quality.”
Developed through a partnership between the Heart Rhythm Society and the American College of Cardiology Foundation, the registry currently contains ICD implantation information for 339,076 ICD procedures performed at 1,432 hospitals across the United States. As of April 2006, the registry became the sole repository for ICD implantation data for Medicare beneficiaries, who account for 68% of patients in the registry.
