Predictors of Mortality Correlated with the SOFA Score in Pediatric VA-ECMO Patients

Abstract

Background: The objective of this study was to analyze mortality predictors in pediatric VA-ECMO patients, correlating these predictors with the pediatric sequential organ failure assessment score (pSOFA). Aim: To enhance prognostic accuracy and support individualized clinical decision-making by evaluating the correlations between mortality predictors and pediatric sequential organ failure assessment (pSOFA) scores in pediatric VA-ECMO patients. Methods: We conducted a retrospective analysis of 80 consecutive pediatric VA-ECMO cases treated at our center between April 2018 and October 2021. Data collection included patient demographics, clinical features, pSOFA scores, and estimated mortality risks. Survival impacts and morbidity factors were also assessed. The overall decannulation and hospital discharge rates were recorded, with a particular focus on patients with congenital cardiac diseases and those experiencing postcardiotomy low cardiac output, who showed the highest survival rates. Results: Our analysis revealed that certain variables significantly influenced survival outcomes in pediatric VA-ECMO patients. These variables included age, weight, genetic disorders, inotropic support, inhaled nitric oxide (NO) usage, hemodiafiltration, duration of hospital stay, active cardiopulmonary resuscitation during cannulation, and various biochemical markers. Notably, the mean pSOFA scores were significantly lower in survivors compared to non-survivors (9.22 ± 1.43 vs. 13.06 ± 2.69, respectively). Overall decannulation and hospital discharge rates were 60% and 48.75%, respectively, with the highest rates observed in patients with congenital cardiac diseases and postcardiotomy low cardiac output (84.6% and 76.9%, respectively). Furthermore, several mortality predictors were identified, which correlated strongly with pSOFA scores. These predictors included the need for inotropic support, elevated levels of lactate and creatinine, a low protein/albumin ratio, and a low pH prior to cannulation. These findings underscore the critical importance of assessing the severity of organ failure and the overall clinical status when determining mortality risk in pediatric VA-ECMO patients. Conclusion: This study offers valuable insights into the association between pSOFA scores and mortality predictors in pediatric ECMO cases. The significant correlation between higher pSOFA scores and increased mortality highlights the necessity for comprehensive risk assessment and vigilant monitoring of clinical status to optimize patient outcomes. Our findings support the integration of pSOFA scores into routine clinical practice for more effective prognostication and individualized patient management in pediatric VA-ECMO.
