PREDICTION MODEL OF MAJOR POSTOPERATIVE INFECTIONS IN PEDIATRIC PATIENTS UNDERGOING CARDIOTHORACIC SURGERY AT A CHILDREN´S HOSPITAL IN LIMA, PERU Background: Major postoperative infections (MPI) are important complications presented after cardiothoracic surgery with a great impact over mortality and length of hospital stay. Several preoperative and intraoperative factors have been associated with postoperative infection risk after cardiothoracic surgery. We developed an internally validated a pediatric major postoperative infection risk prediction model. Methods: A retrospective cohort analyzed 1025 children who underwent cardiothoracic surgery with cardiopulmonary bypass from 2000 to 2010. Bivariate and multivariate logistic regression analyses were used to develop a prediction model for MPI. The model was tested for discrimination and calibration, and validated internally using bootstrapping with 200 replications. Results: From a total of 1025 patients, 59 (5.75%) had at least one episode of MPI (4.78% sepsis, 0.97% mediastinitis, 0% endocarditis). In multivariate analyses, variables associated with MPI were: percentile weight for age <5%, cyanotic disease, RACHS-1, NYHA IV, longer preoperative hospital stays and emergent surgery. The internally validated model had good discrimination with a c-statistic of 0.78 (95% CI 0.72 to 0.83) and calibration. Scores ranged from 12 to 37 corresponding with probabilities of MPI ranging from 5% to 80%, respectively. Conclusion: The prediction model for MPI has good overall performance in children undergoing cardiothoracic surgery. External validation of the model is necessary to evaluate its usefulness in clinical practice.
