Associations Between Postoperative Management in the Critical Care Unit and Adolescent Developmental Outcomes Following Cardiac Surgery in Infancy: An Exploratory Study*
Bibliographic record
Abstract
OBJECTIVES: Children with congenital heart disease are at high risk for developmental sequelae. Most studies focus on preoperative and intraoperative predictors of developmental impairment, with less attention to the postoperative period. The relationship between patient-related factors specific to the postoperative course in the PICU following cardiac surgery with long-term neurodevelopmental outcomes in adolescence was examined. DESIGN: Retrospective chart review of patients previously recruited to a study describing their developmental outcomes in adolescence. SETTING: Single tertiary care pediatric hospital in Canada. PATIENTS: Eighty adolescents, born between 1991 and 1999, with congenital heart disease who required open-heart surgery before 2 years old. MEASUREMENTS AND MAIN RESULTS: Several variables related to acuity of illness and complexity of postoperative course in the PICU were collected. Outcome measures included the Movement-Assessment Battery for Children-2 (motor), Leiter Brief Intelligence Quotient (cognition), and Strength and Difficulties Questionnaire (behavior). Analyses examined associations between PICU variables and long-term outcomes. Longer mechanical ventilation (β = -0.49; p = 0.013) and dopamine use (β = -14.41; p = 0.012) were associated with lower motor scores. Dopamine use was associated with lower cognitive scores (β = -14.02; p = 0.027). Longer PICU stay (β = 0.18; p = 0.002), having an open chest postoperatively (β = 3.83; p = 0.017), longer mechanical ventilation (β = 0.20; p = 0.001), longer inotrope support (β = 0.27; p = 0.002), hours on dopamine (β = 0.01; p = 0.007), days to enteral feeding (β = 0.22; p = 0.012), lower hemoglobin (β = -0.11; p = 0.004), and higher creatinine (β = 0.05; p = 0.014) were all associated with behavioral difficulties. CONCLUSIONS: Several important developmental outcomes in adolescents were associated with factors related to their postoperative course in the PICU as infants. Findings may highlight those children at highest risk for neurodevelopmental sequelae and suggest new approaches to critical care management following open-heart surgery, with the aim of mitigating or preventing adverse long-term outcomes.

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.
