Abstract

Abstract:

Objective

To screen the evaluation tools suitable for perioperative DVT risk prediction in patients with polytrauma, and guide the medical staff to prevent DVT and ensure the safety of high-risk patients.

Methods

A case-control study was conducted. 54 patients with polytrauma and perioperative DVT admitted to a trauma center from June 2017 to October 2022 were selected as the treatment group, and 108 patients with polytrauma without DVT admitted during the same period were randomly selected as the control group. The clinical predictive efficacy of perioperative DVT was determined by receiver operating characteristic curve (ROC), including trauma severity score (ISS), Caprini risk assessment model, and RAPT risk assessment scale.

Results

The areas under the ROC curves of ISS, Caprini and RAPT scales were 0.623 (95% CI: 0.544, 0.698, P<0.01), 0.810 (95% CI: 0.741, 0.867, P<0.01) and 0.805 (95% CI: 0.544, 0.698, P<0.01), respectively. 0.736, 0.863, P<0.01). The optimal critical value of Caprini score was 11.5 points, and the sensitivity and specificity were 68.5% and 85.2%, respectively.

Conclusion

The Caprini and RAPT scale can effectively predict the high-risk population of preoperative DVT among polytrauma patients, but the Caprini scale needs to be reclassified as a risk stratification.
