Quality and Safety in Health Care, Part XLIII: Selected Outcome Studies From the Implantable Cardioverter Defibrillator Registry.

Abstract

To compare outcome results from different institutions in a registry, it is necessary to have a way to take into account differences in the risk characteristics of the patients. This model has been constructed for the Implantable Cardioverter Defibrillator (ICD) Registry, and the most important variables have been identified. In another study, it has also been found that many of these patients have comorbidities, and the mortality rate 60 months after a replacement ICD was 41.2%. In a third study, it was determined that for individuals at least 65 years of age, 60 months after ICD placement, 50.9% of the recipients used hospice services or were dead.
