The Relationship Between Postoperative Complications and Children’s Quality of Life: A Mediation Analysis to Explore the Role of Family Factors
Bibliographic record
Abstract
OBJECTIVES: To 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. DESIGN: We undertook a mediation analysis, to explore the causal pathway, based on data from a prospective, case-matched cohort study. PATIENTS: Six hundred sixty-six children undergoing cardiac surgery. SETTING: Five centers in the United Kingdom. INTERVENTIONS: No intervention. MEASUREMENTS AND MAIN RESULTS: Cases 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. CONCLUSIONS: Parental 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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
