Deep vein thrombosis (DVT) is a blood clot that occurs in a deep vein of the body; pulmonary embolism (PE) occurs when a clot breaks free and enters the arteries of the lungs. DVT and PE comprise venous thromboembolism (VTE), an important and growing public health concern. Hospitalization is a major risk factor for VTE, and many VTE events that occur among hospitalized patients can be prevented. A new program of the U.S. Department of Health and Human Services (Partnership for Patients: Better Care, Lower Costs) aims to reduce the number of preventable VTE cases in hospitals. To estimate the number of hospitalizations with VTE each year in the United States, CDC analyzed 2007-2009 data from the National Hospital Discharge Survey (NHDS). The results of that analysis determined that an estimated average of 547,596 hospitalizations with VTE occurred each year among those aged ≥18 years in the United States. DVT was diagnosed in an estimated annual average of 348,558 hospitalizations, and PE was diagnosed in 277,549; both DVT and PE were diagnosed in 78,511 hospitalizations. Estimates of the rates of hospitalizations with VTE were substantially higher among adults aged ≥60 years compared with those aged 18-59 years. These findings underscore the need to promote implementation of evidence-based prevention strategies to reduce the number of preventable cases of VTE among hospitalized patients.
深静脉血栓形成（DVT）是一种发生在身体深部静脉中的血栓；肺栓塞（PE）是当血栓脱落并进入肺部动脉时发生的。DVT 和 PE 构成静脉血栓栓塞症（VTE），这是一个重要且日益严重的公共卫生问题。住院是 VTE 的一个主要危险因素，许多住院患者中发生的 VTE 事件是可以预防的。美国卫生与公众服务部（患者合作伙伴关系：更好的护理，更低的成本）的一个新项目旨在减少医院中可预防的 VTE 病例数。为了估计美国每年因 VTE 住院的人数，CDC 分析了 2007-2009 年来自全国医院出院调查（NHDS）的数据。该分析的结果确定，在美国，每年估计有 547596 例≥18 岁的成年人因 VTE 住院。每年估计有 348558 例 DVT 住院，277549 例 PE 住院；有 78511 例同时诊断出 DVT 和 PE。与 18-59 岁的成年人相比，≥60 岁的成年人因 VTE 住院的比例要高得多。这些发现强调了需要促进实施基于证据的预防策略，以减少住院患者中可预防的 VTE 病例数。
