Admission to dedicated pediatric cardiac intensive care units is associated with decreased resource use in neonatal cardiac surgery.

OBJECTIVE: Neonates undergoing congenital heart surgery require highly specialized, resource-intensive care. Location of care and degree of specialization can vary between and within institutions. Using a multi-institutional cohort, we sought to determine whether location of admission is associated with an increase in health care costs, resource use and mortality. METHODS: We retrospectively analyzed admission for neonates (<30 days) undergoing congenital heart surgery between 2004 and 2013 by using the Pediatric Health Information Systems database (44 children's hospitals). Multivariate generalized estimating equations adjusted for center- and patient-specific risk factors and stratified by age at admission were performed to examine the association of admission intensive care unit (ICU) with total hospital costs, mortality, and length of stay. RESULTS: Of 19,984 neonates (60% male) identified, 39% were initially admitted to a cardiac ICU (CICU), 48% to a neonatal ICU (NICU), and 13% to a pediatric ICU. In adjusted models, admission to a CICU versus NICU was associated with a $20,440 reduction in total hospital cost for infants aged 2 to 7 days at admission (P = .007) and a $23,700 reduction in total cost for infants aged 8 to 14 days at admission (P = .01). Initial admission to a CICU or pediatric ICU versus NICU at <15 days of age was associated with shorter hospital and ICU length of stay and fewer days of mechanical ventilation. There was no difference in adjusted mortality by admission location. CONCLUSIONS: Admission to an ICU specializing in cardiac care is associated with significantly decreased hospital costs and more efficient resource use for neonates requiring cardiac surgery.

Resource Utilization for Initial Hospitalization in Pediatric Heart Transplantation in the United States.

Pediatric heart transplantation (HT) is resource intensive. Event-driven pediatric databases do not capture data on resource use. The objective of this study was to evaluate resource utilization and identify associated factors during initial hospitalization for pediatric HT. This multicenter retrospective cohort study utilized the Pediatric Health Information Systems database (43 children's hospitals in the United States) of children ≤19 years of age who underwent transplant between January 2007 and July 2013. Demographic variables including site, payer, distance and time to center, clinical pre- and post-transplant variables, mortality, cost, and charge were the data collected. Total length of stay (LOS) and charge for the initial hospitalization were used as surrogates for resource use. Charges were inflation adjusted to 2013 dollars. Of 1,629 subjects, 54% were male, and the median age at HT was 5 years (IQR [interquartile range] 0 to 13). The median total and intensive care unit LOS were 51 (IQR 23 to 98) and 23 (IQR 9 to 58) days, respectively. Total charge and cost for hospitalization were $852,713 ($464,900 to $1,609,300) and $383,600 ($214,900 to $681,000) respectively. Younger age, lower volume center, southern region, and co-morbidities before transplant were associated with higher resource use. In later years, charges increased despite shorter LOS. In conclusion, this large multicenter study provides novel insight into factors associated with resource use in pediatric patients having HT. Peritransplant morbidities are associated with increased cost and LOS. Reducing costs in line with LOS will improve health-care value. Regional and center volume differences need further investigation for optimizing value-based care and efficient use of scarce resources.
