The Clinical Diagnosis of Deep Venous Thrombosis
Why the study?
Does combining symptoms and clinical signs with risk factors in clinical prediction indexes improve the diagnostic accuracy for deep venous thrombosis compared to symptoms and signs alone?
Population

Implication
May improve DVT pretest probability assessment; leaves open prospective validation of combined prediction rules.
Structured PICO
Does combining symptoms and clinical signs with risk factors in clinical prediction indexes improve the diagnostic accuracy for deep venous thrombosis compared to symptoms and signs alone?
P
Population
Patients with suspected deep venous thrombosis (DVT)
I
Intervention
Clinical prediction indexes (combining symptoms, clinical signs, and risk factors)
C
Comparator
Symptoms and clinical signs in isolation
O
Outcome
Accuracy of clinical diagnosis of DVT
Clinical prediction indexes that incorporate risk factors alongside symptoms and signs improve the diagnostic accuracy for suspected deep venous thrombosis.
