Objective: To determine the risk profile of venous thromboembolism (VTE) and evaluate VTE prophylaxis implementation of the hospitalized cancer patients in the DissolVE 2 study. Methods: The data of hospitalized cancer patients in the DissolVE 2 study were analyzed. The risk distribution of VTE, preventive measures and in-hospital VTE events of hospitalized patients with tumors were described by percentage and 95% confident interval (CI). Results: A total of 1 535 cancer patients were included. According to the Padua score, 826 (53.8%) patients were at low risk of VTE, while 709 (46.2%) patients were at high VTE risk. VTE events occurred in 4 low-risk patients (0.5%; 95%CI: 0.1%, 1.2%) and 5 high-risk patients (0.7%; 95%CI: 0.2%, 1.6%). The overall incidence was 0.6% (9/1 535, 95%CI: 0.3%, 1.1%). Among patients with high VTE risk, 666 (93.9%) did not receive any VTE prophylaxis, and only 11 (1.6%) patients received appropriate VTE prophylaxis. Among patients who received VTE prevention, no VTE event was observed. Conclusions: Nearly half of the hospitalized cancer patients are at high risk of VTE, but most of them don't receive VTE prophylaxis. The results reflect the insufficient management of VTE risk for hospitalized cancer patients in China, and improvement of awareness and practice of VTE prophylaxis is urgently needed.
目的： 探讨中国住院患者静脉血栓栓塞症危险因素特征的确定研究(DissolVE 2研究)中内科肿瘤患者的静脉血栓栓塞症(VTE)风险及VTE预防实施情况。 方法： 对DissolVE 2研究中内科肿瘤患者的数据进行再分析，以百分比和95% CI描述内科肿瘤住院患者的VTE风险分布、所接受的预防措施以及院内VTE事件分布。 结果： 1 535例内科肿瘤患者，根据Padua评分，826例(53.8%)为VTE低危患者，709例(46.2%)为VTE高危患者；4例(0.5%，95% CI为0.1%~1.2%)VTE低危患者及5例(0.7%，95% CI为0.2%~1.6%)高危患者发生了VTE事件，总体发生率为0.6%(9/1 535，95% CI为0.3%~1.1%)。VTE高危患者中，666例(93.9%，666/709)未采取任何VTE预防措施，仅11例(1.6%，11/709)接受了恰当的VTE预防措施。全组1 535例患者中，接受VTE预防的患者中，无一例患者发生VTE事件。 结论： 内科肿瘤住院患者中VTE高危患者较多，但大部分患者未进行VTE预防。中国内科肿瘤住院患者的VTE风险管理严重不足，临床中VTE的预防意识及实施能力亟待提高。.
