Value of Preoperative Risk Adjustment in Congenital Heart Surgery Score versus the Vasoactive-ventilation-renal Score for Predicting Postoperative Outcomes in Neonates and Children

Abstract Objectives: The objectives of this study was to compare the postcardiac surgery vasoactive-ventilation-renal (VVR) score with the preoperative risk adjustment in congenital heart surgery score (RACHS) for predicting postsurgical outcomes in children. Materials and Methods: This retrospective cohort study enrolled 70 patients between January 2018 and December 2019. Correlation and strength of association were assessed for RACHS and VVR scores against intensive care unit (ICU) length of stay (LOS) >5 days and hospital LOS >7 days. The receiver operating characteristic analysis was done to generate coordinates, cutoff values, and accuracies. Results: The median age, RACHS score, and bypass time were 6 months, 2, and 93 min, respectively. There was a positive correlation between the VVR score and hospital LOS, ICU LOS, length of intubation, and RACHS at all time points (0, 12, 24, and 48 h) with assigned cutoff values. Conclusions: There was a positive correlation between the RACHS and VVR scores. The VVR scores were valid for short-term prognostic outcomes.
