Abstract
Objective To evaluate the values of the scores of Wells,Kahn,St. André,Constans in diagnosis of deep venous thromboembolism( DVT). Methods A total of 278 suspected DVT patients hospitalized in General Hospital of Ningxia Medical University from July 2006 to March 2009 underwent scores of Wells,Kahn,St. André,Constans,respectively. We take low possibility of DVT of each score as negative result,middle and high possibility of DVT as positive result,and CT venog-raphy( CTV)and( or)ultrasonography as gold standard. The sensitivity,specificity,positive predictive value,negative pre-dictive value and ROC area under curve( AUC) of the scores in DVT diagnosis were calculated. ResUlts The sensitivity,spe-cificity,positive predictive value and negative predictive value,ROC AUC of Wells Score in DVT diagnosis were 92. 3%, 48. 9%,65. 7%,85. 7%,0. 845,respectively;those of Kahn Score were 64. 3%,29. 6%,49. 2%,44. 0%,0. 526,re-spectively;those of St. André Score were 90. 2%,51. 8%,66. 5%,83. 3%,0. 761,respectively;those of Constans Score were 95. 8%,23. 0%,56. 8%,83. 8%,0. 755,respectively. By Z test,there was no significant differences in DVT diagno-sis in scores of St. André and Constans,and there was difference between any other 2 scores(P<0. 05). ConclUsion Com-parison of DVT diagnosis in scores of Wells,Kahn,St. André,Constans has found that the diagnostic efficiency of Wells score is the highest,which is more suitable for Chinese people.关键词
