The Caprini Risk Score (CRS) is one of the most widely used risk assessment models for venous thromboembolism (VTE). A well-validated patient-completed CRS form may allow patients to self-report and simplify the evaluation by health care workers. The Chinese version of the CRS was optimized for easy understanding in a pilot study. The amended CRS form was completed by prospectively recruited patients and blinded nurses. The agreement levels of the individual questions and the total scores of patient and nurse-completed forms were compared using the Kappa value. The total scores were used for risk stratification of patients. Correlation and differences between patient and nurse-completed forms were analyzed using the Spearman correlation and Bland-Altman method, respectively. We recruited 504 medical patients and 513 surgical patients, aged 52.7 ± 16.3 years, of which 443 (43.6%) were men, and 91.6% of the patients were educated beyond junior high school. The patients spent less time to complete the form compared with trained nurses. There was good question-to-question agreement between patient and nurse-completed CRS ( >0.6 for most questions, < 0.0001). The total scores also showed good agreement ( = 0.6097, < 0.0001), and enabled the classification of patients into different risk groups. The patient and nurse-derived scores were highly correlated (Spearman's = 0.84), and without extreme values ( < 0.0001). We have created and verified a Chinese version of the patient-completed CRS, which showed good agreement and correlation with nurse-completed CRS. CRS represents a suitable tool for VTE risk assessment of hospitalized patients in China.
卡普里尼风险评分（CRS）是静脉血栓栓塞症（VTE）应用最广泛的风险评估模型之一。经过充分验证的患者填写版CRS表格可让患者进行自我报告，并简化医护人员的评估工作。 在一项试点研究中，对CRS的中文版进行了优化，以使其易于理解。修订后的CRS表格由前瞻性招募的患者和不知情的护士填写。使用Kappa值比较各个问题的一致性水平以及患者和护士填写表格的总分。总分用于对患者进行风险分层。分别使用Spearman相关性分析和Bland-Altman方法分析患者与护士填写表格之间的相关性和差异。 我们招募了504名内科患者和513名外科患者，年龄为52.7±16.3岁，其中443名（43.6%）为男性，91.6%的患者受过初中以上教育。与经过培训的护士相比，患者填写表格所花费的时间更少。患者和护士填写的CRS在各个问题之间具有良好的一致性（大多数问题的Kappa值>0.6，P<0.0001）。总分也显示出良好的一致性（Kappa值=0.6097，P<0.0001），并能够将患者分为不同的风险组。患者和护士得出的分数高度相关（Spearman相关性系数=0.84），且无极端值（P<0.0001）。 我们创建并验证了患者填写版的CRS中文版，其与护士填写版的CRS具有良好的一致性和相关性。CRS是中国住院患者VTE风险评估的合适工具。
