Key result
Preoperative model using age and BMI yields 0.68 AUC for predicting VTE after thoracolumbar fusion.
Why the study?
The study was conducted to identify preoperative risk factors for VTE and develop a predictive model suitable for integration into electronic health records.
What are the preoperative risk factors for VTE after fusion for degenerative conditions of the thoracolumbar spine, and can a predictive model be developed?
Observational
Yes
What are the preoperative risk factors for VTE after fusion for degenerative conditions of the thoracolumbar spine, and can a predictive model be developed?
A predictive model using preoperative risk factors like age and BMI can identify patients at risk for VTE after thoracolumbar spine fusion with acceptable discrimination (AUC 0.683).

May inform preoperative VTE risk counseling in thoracolumbar fusion; leaves open external validation before clinical use.
BACKGROUND: The purpose of this study was to identify preoperative risk factors for VTE and develop a predictive model that can be integrated into electronic health records (EHRs). METHODS: Retrospective review of patients undergoing thoracolumbar fusion from 2016 to 2018 in the National Surgical Quality Improvement Program database was performed. RESULTS: Increasing age, BMI, and several other factors were significant predictors of increased risk for postoperative VTE. The predictive model had an area under the curve of 0.683, indicating acceptable discrimination. DISCUSSION: Our findings build upon previous studies by presenting a model equation that can be rapidly integrated into EHRs for validation.

Kelly et al. (2020) conducted an observational in Degenerative conditions of the thoracolumbar spine. Preoperative risk factors (including age and BMI) was evaluated on Postoperative venous thromboembolism (VTE) (AUC 0.683). A predictive model using preoperative risk factors such as increasing age and BMI showed acceptable discrimination for postoperative VTE after thoracolumbar fusion (AUC 0.683).
