Complications in pediatric scoliosis surgery.

BACKGROUND Scoliosis surgery in childhood is associated with a range of postoperative complications that may require admission to the pediatric intensive care unit (PICU) or high-dependency unit (HDU). AIM The aim of this study was to identify preoperative factors associated with PICU and HDU admissions after corrective surgery and devise a scoring system that could be used by clinicians to predict the level of dependency required postoperatively. METHODS A retrospective case note review was carried out in 90 patients who underwent corrective scoliosis surgery at Sheffield Children's Hospital (SCH) between January 2008 and October 2010. Predictors of PICU and HDU requirement postoperatively were identified and a simple scoring system created using multiple logistic regression and receiver operator characteristic (ROC). RESULTS There was a statistically significant difference in the preoperative parameters (pulmonary function, Cobb angle, and number of vertebrae fused) of those patients who required PICU or HDU care compared with those who did not. The area under the receiver operator characteristic curve for the final scoring system was 0.95 for PICU admission and 0.87 for HDU admission at the optimal cut-off point, demonstrating good diagnostic accuracy. CONCLUSIONS The authors have identified a significant relationship between preoperative variables and the levels of dependency required postoperatively and have proposed a scoring system which can be used to aid decision-making involving bed planning for patients after corrective scoliosis surgery. However, this work is based on the clinical course of a single set of patients who had surgery in a single tertiary center and has not been tested on patients from other centers.
