英国价值定价理念对我国医保药品报销政策的启示

本文在梳理英国医保药品报销政策的基础上,通过对价值定价理念的深入研究和理解,系统探讨其在报销政策制定过程中对药品目录遴选、价值测算、支付标准确定、医保基金平衡和报销效益评估的作用机制,并深入思考通过价值定价理念建立起的药物警戒体系与药品报销政策间的衔接机制。在此基础上总结价值定价理念的特点、应用阶段和具体操作方法,以期为我国提供借鉴。     

Spontaneous reports of hypersensitivity adverse drug reactions in Portugal: a retrospective analysis

ABSTRACT

Background

Hypersensitivity adverse drug reactions (ADRs) are usually serious, unpredictable, and associated with high morbidity and mortality. This study describes cases of hypersensitivity ADRs spontaneously reported in Central Portugal.     

Reference set for performance testing of pediatric vaccine safety signal detection methods and systems

BackgroundSafety signal detection in spontaneous reporting system databases and electronic healthcare records is key to detection of previously unknown adverse events following immunization. Various statistical methods for signal detection in these different datasources have been developed, however none are geared to the pediatric population and none specifically to vaccines. A reference set comprising pediatric vaccine-adverse event pairs is required for reliable performance testing of statistical methods within and across data sources.MethodsThe study was conducted within the context of the Global Research in Paediatrics (GRiP) project, as part of the seventh framework programme (FP7) of the European Commission. Criteria for the selection of vaccines considered in the reference set were routine and global use in the pediatric population. Adverse events were primarily selected based on importance. Outcome based systematic literature searches were performed for all identified vaccine-adverse event pairs and complemented by expert committee reports, evidence based decision support systems (e.g. Micromedex), and summaries of product characteristics. Classification into positive (PC) and negative control (NC) pairs was performed by two independent reviewers according to a pre-defined algorithm and discussed for consensus in case of disagreement.ResultsWe selected 13 vaccines and 14 adverse events to be included in the reference set. From a total of 182 vaccine-adverse event pairs, we classified 18 as PC, 113 as NC and 51 as unclassifiable. Most classifications (91) were based on literature review, 45 were based on expert committee reports, and for 46 vaccine-adverse event pairs, an underlying pathomechanism was not plausible classifying the association as NC.ConclusionA reference set of vaccine-adverse event pairs was developed. We propose its use for comparing signal detection methods and systems in the pediatric population.     

关注药物不良反应信号检测研究中的常见问题

药物不良反应(ADR)信号检测是药物上市后药物警戒的一种重要研究方法。近年来, 我国ADR信号检测研究文献的数量明显增加。但该类研究中尚存在许多问题, 如对ADR信号的概念认识不清、信号检测研究的目的不明、信号来源局限、对检测数据未进行很好的处理、数据挖掘算法单一、数据选择的时间范围过短、未对信号检测中的偏倚进行处理和分析等。本文对这些常见问题谈一些看法, 希望对我国ADR信号检测研究的质量提升有所帮助。
