An attempt was made to identify all patients diagnosed as having deep vein thrombosis (DVT) in a large teaching hospital during one year. A review of the radiology records showed that 124 (81%) of the 154 venograms performed were for suspected DVT, and that the diagnosis was confirmed in 57 (46%). During the same period, the Hospital Activity Analysis (HAA) records revealed 174 episodes classified as 'phlebitis or thrombophlebitis' in 162 patients. Only 37 of these episodes (21%) had been confirmed by X-ray venography and at least 29 patients were incorrectly classified by HAA. 'Medical' patients accounted for 54% of the episodes of DVT, yet in only 25% of these was the diagnosis confirmed by venography, while 'surgical' DVTs were less frequent but were more often confirmed by venography.
我们尝试确定在一家大型教学医院中，一年内所有被诊断为患有深静脉血栓形成（DVT）的患者。对放射学记录的审查显示，154次静脉造影中有124次（81%）是针对疑似DVT进行的，其中57次（46%）确诊。同一时期，医院活动分析（HAA）记录显示，162名患者中有174例被归类为“静脉炎或血栓性静脉炎”。这些病例中只有37例（21%）通过X线静脉造影得到确诊，并且至少有29名患者被HAA错误分类。“内科”患者占DVT病例的54%，但其中只有25%通过静脉造影确诊，而“外科”DVT病例较少，但通过静脉造影确诊的比例更高。
