BACKGROUND: Long-term outcomes and predictors of mortality after implantable cardioverter-defibrillator (ICD) implantation related complication are unclear.
OBJECTIVE: The purpose of this study was to determine the risk of mortality and hospitalization after complication during ICD implantation and identify predictors of adverse outcomes.
METHODS: We performed a retrospective registry study of Medicare beneficiaries who were first-time ICD recipients enrolled in the National Cardiovascular Data Registry ICD Registry between January 2006 and March 2010. Mortality and hospitalization rates were examined using Kaplan-Meier survival analysis and multivariable Cox proportional hazards regression analysis. Covariates associated with mortality 3 years after ICD implantation complication were investigated.
RESULTS: The study cohort comprised 136,143 Medicare beneficiaries. Complications during the index hospitalization occurred in 7046 patients (5.18%), and complications within 90 days of device implantation occurred in 10,005 patients (7.34%). In adjusted analyses, complications within 90 days of implantation were associated with an increased risk of all-cause mortality at 1 year (hazard ratio [HR] 1.13; 95% confidence interval [CI] 1.05-1.20; P = .006) and 3 years (HR 1.09; 95% CI 1.05-1.13; P <.0001). These results were consistent for a combined endpoint of all-cause mortality or hospitalization. Patient, device, and hospital characteristics associated with 3-year mortality were similar between those with and those without complications.
CONCLUSION: Among Medicare beneficiaries, the occurrence of complications within 90 days of ICD implantation was associated with increased risk of all-cause mortality and all-cause mortality or hospitalization at 1 and 3 years. Patient, procedure, and hospital characteristics associated with mortality at 3 years after implantation were similar regardless of whether acute procedural complication occurred.
