BackgroundWe examined equity of access to implanted cardioverter defibrillators (ICDs) in New Zealand in 2010 by district health board (DHB), ethnicity and socioeconomic status.MethodsAll new ICD recipients in 2010 were examined according to home district health board, ethnicity according to the national health database, and socioeconomic status using the NZDep index.ResultsDuring 2010, 352 new ICDs were implanted nationwide, giving an overall implantation rate of 80.6/million. However, implant rates varied significantly across the 20 DHBs with the highest implant rate observed in Tairawhiti at 192.3/million, and the lowest at 22/million in the Nelson region. There was also significant variation in implant rate by ethnicity, with Maori ethnicity at an implant rate of 114/million, European patients at 83/million, Pacific Island patients at 47/million and Asian patients an implant rate of 32/million. There was no significant difference in number of implants by socioeconomic decile.ConclusionsThe variance in implantation rate by district health board and by ethnicity suggests that access to ICD therapy is not equitable in New Zealand. Investigation into causes of inequity of access is required.Copyright © 2012 Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) and the Cardiac Society of Australia and New Zealand (CSANZ).
