How to utilize a new pre-test probability score for diagnosis of deep vein thrombosis before surgery?

Abstract

Venous thromboembolism, dominantly from deep vein thrombosis (DVT), is a serious perioperative complication that is associated with mortality and morbidity [1]. We congratulate Hamamoto and colleagues, who developed a novel pre-test probability score to predict the incidence of DVT prior to major surgery [2]. Several concerns have been raised.
