Item A Descriptive study of deep vein thrombosis (DVT) in a tertiary care hospital(Sri Lanka Medical Association, 2008) Botheju, W.I.K.; Navaratne, A.C.R.; Somarathne, C.K.; Balasooriya, B.L.P.P.; Wijebandara, R.J.K.S.; Mandawala, M.B.S.N.; Ruwanpathirana, T.; Kasturiratne, K.T.A.A.; Hewawitharana, C.P.; Rathnasena, B.G.N.; Fernando, P.; Wijesinghe, P.S.; Premawardhena, A.OBJECTIVE: The incidence and risk factors for DVT are not well established for the Sri Lankan population. Though believed to be an effective screening tool for DVT, the Well's Clinical score is not widely used in Sri Lankan hospitals. DESIGN, SETTING AND METHODS: Over a period of 8 months, a total of 23274 patients who presented to four units (including one general medical, one general surgical, one Gynaecology & Obstetrics, and the Orthopedic ward) of the North Colombo (Teaching) Hospital were screened for asymmetrical limb swelling more than 2 cm. The latter group were subjected to risk assessment for DVT, Well's scoring and CDU (Colour Duplex Ultrasound). RESULTS: Of the 23274 patients, 93 (0.4%) had unilateral limb swelling of which 12 (12.9%) were CDU confirmed to have DVT (0.5 per 1000). Limb swelling for more man two weeks was significantly commoner among DVT patients when compared to those without DVT (75% Vs 25.9%: p=0.001). None of the patients had been evaluated with the Well's score as a guide to refer for CDU by the relevant clinical teams. In 55 (59.1%) subjects, Well's score was 0 or less (minimum probability of DVT) and there were no subjects with DVT in this group. All 12 patients with DVT had a moderate or high probability Wells score. CONCLUSIONS: Overall incidence of DVT in the study population was lower than in other comparable published studies from Asia. Well's score which was underused by the clinicians is a highly sensitive screening tool for DVT.
