摘要
本章主要介绍了药品有效性评价的定义、流程和具体评价方法.药品有效性评价通过对比待评价药品与参比药品在治疗特定疾病时的临床治疗效果,评估待评价药品是否能够显著改善患者状况并获得重要的健康收益.开展药品有效性评价首先要明确评价问题,即按照PICO原则对目标人群、待评价药品、参比药品、结局指标等进行具化,然后根据药品特征、疾病特征、文献资料的充分程度和数据的可及性选择适宜的评价方法,包括二次研究、真实世界研究和RCT.二次研究系统收集和分析现有文献;真实世界研究基于实际医疗环境中的数据,反映药品在真实条件下的治疗效果;RCT则通过随机化分组,阐明干预措施与结局之间的因果关系.此外,本章还讨论了质量控制的重要性,确保评价结果的真实性、正确性及可靠性.
Abstract
This chapter primarily introduces the definition,process,and specific evaluation methods of drug effectiveness evaluation.Drug effectiveness evaluation compares the clinical therapeutic effects of a subject drug with a reference drug in treating specific diseases,to assess whether the subject drug can significantly improve patient outcomes and achieve important health benefits.The evaluation process begins by clarifying the evaluation question,which involves defining the target population,the drug under evaluation,the reference drug,and outcome measures according to the PICO principle.Based on the characteristics of the drug,the disease,the sufficiency of existing literature,and the availability of data,appropriate evaluation methods are selected,including secondary research,real-world studies,and RCTs.Secondary research systematically collects and analyzes existing literature;real-world studies use data from actual medical environments to reflect the drug's therapeutic effects;RCTs use randomization to clarify the causal relationship between the intervention and outcomes.Additionally,this chapter discusses the importance of quality control to ensure the authenticity,accuracy,and reliability of the evaluation results.
