Background. Deep Vein Thrombosis (DVT) is the venous thrombus in lower limbs. Diagnosis is done by venography or ultrasound compression. However these examinations are not available yet in some health facilities. Therefore many scoring systems developed for the diagnosis of DVT. Scoring method is practical and safe to use in addition to efficacy, and effectiveness in terms of treatment and costs. The existing scoring systems are wells score, caprini score and padua score. There have been many studies comparing the accuracy of these score but not yet in Medan. Therefore, we are interested to hold a comparative research of wells score, caprini score and padua score in Medan.

Methods. An observational, analytical, case-control study to perform diagnostic tests on the wells, caprini and padua score for predicting the risk of DVT. The study was conducted at H. Adam Malik Hospital in Medan.

Resulst. From a total of 72 subjects, 39 people (54.2%) are men and the mean age are 53.14 years. Wells score, caprini score and padua score has a sensitivity of 80.6%; 61.1%, 50% respectively; specificity of 80.65; 66.7%; 75% respectively, and accuracy of 87.5%; 64.3%; 65.7% respectively.

Conclutions. Wells score have better sensitivity, specificity and accuracy than caprini and padua score in diagnosing DVT.
