Key result
Surveillance duplex scanning detects DVT in ~3% of trauma admissions but correlates poorly with VTE scores.
Why the study?
Does surveillance duplex scanning prevent pulmonary embolism in trauma patients?
Observational (n=10,141)
Does surveillance duplex scanning prevent pulmonary embolism in trauma patients?
Adherence to an evidence-based VTE prophylaxis protocol is more important than surveillance duplex scanning in preventing VTE in trauma patients.
No takes yet. Share an insight, caveat, or question.
Surveillance duplex detects few VTE events with poor risk-score correlation in trauma; leaves open whether routine scanning adds benefit beyond optimized prophylaxis.
Cipolle et al. (2002) conducted an observational in Trauma (n=10,141). Surveillance duplex scanning was evaluated on Incidence of deep venous thrombosis (DVT) and pulmonary embolism (PE). Surveillance duplex scanning in trauma patients identified DVT in 2.5% and PE in 0.3% of admissions, with poor correlation between VTE risk score and DVT incidence (r2 = 0.27).
