诊断试验:

Diagnostic Tests:

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

术后3月内症状性VTE,包括症状性下肢深静脉血栓(DVT)及症状性肺栓塞(PE),其诊断需结合症状及相关检查(下肢深静脉彩超或下肢深静脉造影或肺动脉CTA)。当患者于出现下肢疼痛、肿胀、周径发生改变、Homans征阳性等疑似DVT症状,则行双下肢深静脉彩超 (ultrasonography,USG) 检查,如果提示阳性,则诊断为症状性DVT。如患者出现胸闷、胸痛、咯血、血氧饱和度下降等情况时,完善凝血及血气分析等化验检查,完善 USG ,肺动脉CTA或肺动脉造影等检查,如果提示阳性,则诊断为症状性PE。

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

Symptomatic VTE within 3 months after surgery, including symptomatic deep vein thrombosis (DVT) and symptomatic pulmonary embolism (PE), should be diagnosed according to symptoms and related examinations (lower extremity deep vein ultrasound or lower extremity deep vein angiography or pulmonary artery CTA).

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

Caprini血栓风险评分,该评分通过对不同潜在风险因素赋值,以总分高低预测VTE风险大小。

Index test:

Caprini risk assessment model. This model assigns different values to different potential risk factors and predicts the risk of VTE according to the total score.

目标人群(可以是某种疾病患者或正常人群,详细描述其疾病特征,注意应纳入符合分布特点的全序列病例,具有良好的代表性)

髋膝关节置换术患者

Sample size:

8000

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):
