A Clinical Risk Model for Surgical Site Infection Following Pediatric Spine Deformity Surgery

i) Study design: Multi-center retrospective study.
ii) A total of 3,092 spinal deformity surgeries were included, in which there were 132 cases of SSI (4.3%).
iii) The final model achieved adequate discrimination (area under the receiver operating characteristic curve: 0.76), as well as calibration and no overfitting.
iv) Predictors included in the model were nonambulatory status, neuromuscular etiology, pelvic instrumentation, procedure time ≥7 hours, American Society of Anesthesiologists grade >2, revision procedure, hospital spine surgical cases <100/year, abnormal hemoglobin level, and overweight or obese body mass index.
