ObjectivesThe use of ventricular assist devices for pediatric patients with heart failure is increasing, but is associated with significant morbidity and mortality. Our objectives were to describe the admission outcomes and resource utilization of pediatric patients supported with ventricular assist devices, utilizing a multicenter database.Data SourcesPediatric Health Information System database (comprising 49 nonprofit children's hospitals).Study SelectionRetrospective cohort analysis of the database from January 2006 to September 2015 for all admissions less than or equal to 21 years old with ventricular assist device implantation.Data ExtractionThe primary outcome was hospital mortality. The secondary outcomes were hospital length of stay and adjusted cost.Data SynthesisWe analyzed 744 ventricular assist device implantations (740 patients), 422 (57%) males, and 363 (49%) non-Hispanic white. Median age at admission was 5.9 years (interquartile range, 0.9-13.5 yr), and median length of stay was 69 days (interquartile range, 36-122 d). The overall hospital mortality was 188 (25%), whereas 395 (53%) were transplanted and 141 (19%) were discharged on ventricular assist device. Extracorporeal membrane oxygenation was used, in addition to ventricular assist device, in 340 (46%). The majority of ventricular assist device implantations (453, 61%) were from 2011 to 2015 (compared to 2006-2010). More patients discharged on ventricular assist device from 2011 to 2015 (23% vs 13% in 2006-2010; p = 0.001). There was no difference in median age, mortality, length of stay, or adjusted costs between these time periods. On multivariable analysis, underlying congenital heart disease, renal failure, liver congestion, sepsis, cerebrovascular accident, and extracorporeal membrane oxygenation were associated with hospital mortality. Sepsis and ventricular assist device replacement/repair were associated with higher adjusted cost and longer length of stay.ConclusionsThe pediatric ventricular assist device experience continues to grow, with a significant increase in the number of patients undergoing ventricular assist device implantation and a higher proportion being discharged from hospital on ventricular assist device support in recent years. Underlying congenital heart disease, renal failure, sepsis, cerebrovascular accident, and extracorporeal membrane oxygenation are significantly associated with hospital mortality.
