Extract

To the Editor: The study by Dr Al-Khatib and colleagues1 reported that 22.5% of primary prevention ICD implants in the United States do not meet evidence-based guidelines. It has been interpreted to mean that these implants were unnecessary.2

Translation of medical research into care of individual patients is an imperfect science.3 Practice guidelines are an important starting point for clinical decision making, but they are not a substitute for clinical judgment, which can provide independent value.4 The National Cardiovascular Data Registry (NCDR) ICD Registry analyzed by the authors is not designed to determine the medical necessity of ICD implants that do not meet evidence-based guidelines.
