【摘要】 目的 构建血液病患者PICC导管相关性静脉血栓(PICC-RVT)风险评估体系。方法 检索PICC-RVT相关文献，建立初始指标池；通过小组讨论，初步拟定血液病患者PICC-RVT风险评估指标；采用德尔菲法进行两轮专家函询，利用层次分析法确定指标权重。结果 两轮函询专家积极程度分别为100%、88.0%,专家权威系数分别为0.831、0.925,Kendall’s W系数分别为0.227、0.364。最终形成的血液病患者PICC-RVT风险评估体系包含一级指标4个、二级指标13个、三级指标43个。结论 构建的血液病患者PICC-RVT风险评估体系具有一定科学性，为评估血液病患者PICC-RVT风险提供了工具。患者、治疗、导管以及操作是血液病患者PICC-RVT风险评估需重点关注的内容。更多还原

【Abstract】 Objective To develop a risk assessment system for Peripherally Inserted Central Catheter Related Venous Thrombus(PICC-RVT) in patients with hematological diseases. Methods PICC-RVT related literature was retrieved and initial index pool was established. Through group discussion, the PICC-RVT risk assessment indexes of patients with hematological diseases were preliminarily developed. Two rounds of expert correspondence were conducted by Delphi method, and the index weights were determined by analytic hierarchy process. Results The positive degree of the two rounds of correspondence consultation with experts was 100% and 88.0%, the expert authority coefficient was 0.831 and 0.925, and the Kendall’s W coefficient was 0.227 and 0.364, respectively. The final PICC-RVT risk assessment system for patients with hematological diseases contains 4 first-level indicators, 13 second-level indicators and 43 third-level indicators. Conclusion The established PICC-RVT risk assessment system for patients with hematologic diseases is scientific and provides a tool for assessing the risk of PICC-RVT in patients with hematologic diseases. Patients, treatments, catheters, and procedures are key aspects of PICC-RVT risk assessment in patients with hematologic diseases.更多还原
