研究目的:

目前恶性血液病化疗后骨髓抑制发生出血,主要依据单一的血小板计数来评估出血风险,但大量临床观察表明,即使血小板计数相同,不同血液病患者的出血风险也存在巨大差异。这提示除血小板数量外,还存在其他重要的影响因素,如患者年龄、合并症(如感染、肝功能不全)、凝血功能状态、化疗方案强度、既往出血史等。缺乏一个综合多因素的、量化的风险评估工具,导致预防性血小板输注和促血小板生成药物使用的指征过于宽泛或保守,造成医疗资源浪费或预防不足。本研究通过建立多因素模型,建立出血预防机制和出血紧急治疗流程。  

Objectives of Study:

At present, the bleeding risk of bone marrow suppression after chemotherapy in hematologic malignancies is mainly evaluated based on a single platelet count, but a large number of clinical observations show that even if the platelet count is the same, the bleeding risk of patients with different hematologic diseases also has great differences. This suggests that in addition to the number of platelets, there are other important influencing factors, such as the patient's age, comorbidities (such as infection, liver dysfunction), coagulation function status, chemotherapy regimen intensity, previous bleeding history, etc. The lack of a comprehensive multifactorial and quantitative risk assessment tool has led to too broad or conservative indications for the use of preventive platelet transfusion and thrombopoiesis promoting drugs, resulting in waste of medical resources or insufficient prevention. In this study, a multifactorial model was established to establish the bleeding prevention mechanism and bleeding emergency treatment process.
