Abstract 18314: Adult Congenital Heart Failure Admissions in the United States: Trends, Resource Utilization & Mortality

Objectives: The primary objective of this study was to characterize temporal trends, health resource utilization, and outcomes in heart failure (HF) hospitalizations among adults with congenital heart disease. Background: Understanding HF hospitalization patterns and resource needs among adult congenital heart disease (ACHD) patients is necessary to address the future care needs of this rapidly expanding population. Methods: The Nationwide Inpatient Sample (NIS) is a stratified sample designed to approximate a 20% sample of US community hospitals; sampling weights are used to produce a national sample. Using the NIS we compared trends in ACHD related HF hospitalizations versus non-congenital HF admissions between 1998 and 2011. Trends during the study period were evaluated using the Mann-Kendall trend test. ACHD-related HF hospitalization outcomes were assessed including mortality and high resource utilization (HRU) admissions. Multivariable logistic regression was used to examine factors influencing mort...
