Cost Variation Across Centers for the Norwood Operation.

ABSTRACT: BACKGROUND:The Norwood operation is associated with high health care utilization, and prior studies reported substantial variability in Norwood costs across centers. However, specific factors driving this cost variation are unclear. We assessed center variability in Norwood costs and underlying mechanisms in a multicenter cohort. METHODS:Clinical data from the Pediatric Heart Network Single Ventricle Reconstruction trial were linked with cost data from the Children's Hospital Association Inpatient Essentials database. Center variation was assessed by modeling Norwood costs adjusted for baseline patient characteristics, and the relationship with complications, length of stay (LOS), and specific cost categories was examined. Patients undergoing transplantation or stage 2 palliation during the Norwood admission were excluded. RESULTS:Nine centers (332 patients) were included. Adjusted mean cost/case varied 4.6-fold across centers (range: $50,559 to $230,851, p < 0.001). In addition, variation was found across centers in the adjusted mean number of complications/case (2.6-fold variation) and adjusted mean LOS/case (1.9-fold variation). Differences in complications explained 63% of the cost variation across centers. After accounting for complications, differences in LOS explained 66% of the remaining cost variation. Seven specific complications were found to occur more frequently at high-cost centers: pleural effusion, seizures, wound infection, thrombus, liver dysfunction, sepsis, necrotizing enterocolitis (all p < 0.001). With regard to types of cost, room and board/supplies and laboratory costs were the primary drivers of cost variation across centers. CONCLUSIONS:This study identified several factors associated with center variation in Norwood costs, which may be targeted in subsequent initiatives aimed at both improving quality of care and reducing costs.

Project description:Background Intensive monitoring has been associated with a lower death rate between the Norwood operation and superior cavopulmonary connection, possibly due to early identification and effective treatment of residual anatomic lesions like recoarctation before lasting harm occurs. Methods and Results Neonates undergoing a Norwood operation and receiving interstage care at a single center between January 1, 2005, and September 18, 2020, were studied. In those with recoarctation, we evaluated association of era ([1] preinterstage monitoring, [2] a transitional phase, [3] current era) and likelihood of hemodynamic compromise (progression to moderate or greater ventricular dysfunction/atrioventricular valve regurgitation, initiation/escalation of vasoactive/respiratory support, cardiac arrest preceding catheterization, or interstage death with recoarctation on autopsy). We also analyzed whether era was associated with technical success of transcatheter recoarctation interventions, major adverse events, and transplant-free survival. A total of 483 subjects were studied, with 22% (n=106) treated for recoarctation during the interstage period. Number of catheterizations per Norwood increased (P=0.005) over the interstage eras, with no significant change in the proportion of subjects with recoarctation (P=0.36). In parallel, there was a lower likelihood of hemodynamic compromise in subjects with recoarctation that was not statistically significant (P=0.06), with a significant difference in the proportion with ventricular dysfunction at intervention (P=0.002). Rates of technical success, procedural major adverse events, and transplant-free survival did not differ (P>0.05). Conclusions Periods with interstage monitoring were associated with increased referral for catheterization but also reduced likelihood of ventricular dysfunction (and a suggestion of lower likelihood of hemodynamic compromise) in subjects with recoarctation. Further study is needed to guide optimal interstage care of this vulnerable population.
