A novel risk calculator predicting surgical site infection after spinal surgery in patients with cerebral palsy

i) Study design: Multicenter retrospective cohort study of pediatric patients with CP who underwent spinal fusion.
ii) Among the 255 patients in the development stage, risk of SSI was 11%.
iii) A final prediction model included non-ambulatory status (odds ratio [OR] 4.0), diaper dependence (OR 2.5), age younger than 12 years (OR 2.5), major coronal curve magnitude greater than 90° (OR 1.3), behavioral disorder/delay (OR 1.3), and revision surgery (OR 1.3) as risk factors.
iv) This model had a predictive ability of 73.4% for SSI, along with excellent calibration ability (p = 0.878).
