    ObjectivesTo explore whether postoperative morbidities after pediatric cardiac surgery affected children's health-related quality of life (HRQOL) at 6 months, through potentially modifiable parental psychological factors.DesignWe undertook a mediation analysis, to explore the causal pathway, based on data from a prospective, case-matched cohort study.PatientsSix hundred sixty-six children undergoing cardiac surgery.SettingFive centers in the United Kingdom.InterventionsNo intervention.Measurements And Main ResultsCases of morbidity were identified early after pediatric cardiac surgery, and matched controls with no morbidities were identified at discharge. Four mediators were assessed at 6 weeks after surgery, using the PedsQL Family Impact Module (Parent HRQOL and Family Function) and the PHQ-4 (Anxiety and Depression). The study outcome of child HRQOL was assessed at 6 months with the PedsQL. Of 666 children, 408 (65% of those surviving) contributed to the primary outcome. Children who had extracorporeal life support (ECLS) ( n = 11) ( p < 0.05) and multiple morbidities ( n = 62) ( p < 0.01) had worse 6-month HRQOL than those with a single morbidity ( n = 125) or no morbidity ( n = 209). After adjustment for case mix complexity and sociodemographic variables, there were significant indirect effects of parent HRQOL at 6 weeks, on the PedsQL Total Score (ECLS, -5.1 [-8.4 to -1.8]; p = 0.003; multiple morbidities, -2.1 [-3.7 to -0.5]; p = 0.01), PedsQL Physical Score (ECLS, -5.1 [-8.7 to -1.4]; p = 0.007; multiple morbidities, -2.1 [-3.8 to -0.4]; p = 0.016), and PedsQL Psychosocial Score (ECLS: -5.3 [-8.7 to -1.8); p = 0.003; multiple morbidities, -2.2 [-3.9 to -0.5]; p = 0.01). The proportion of the total effect of ECLS and multiple morbidity on the study outcomes mediated through parent HRQOL ranges between 18% and 61%. There was no evidence that the other three mediators had indirect effects on the study outcome.ConclusionsParental HRQOL at 6 weeks after surgery contributes to child HRQOL at 6 months, among those with the severest types of morbidity, and as such should be a target for future interventions.Copyright © 2023 by the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies.
