Methodological search filter performance: assessment to improve efficiency of evidence information retrieval.

NICE需要研究来帮助它决定哪些治疗和诊断方法应该由NHS资助。NICE强调了对审查研究证据的方法进行研究的必要性。识别研究是大多数NICE审查的基础。方法学搜索过滤器广泛用于确定特定的研究设计，如随机对照试验或经济评估。搜索过滤器是精心挑选的单词和短语集合，用于搜索数据库以识别研究。人们对搜索过滤器在搜索研究方面的效果知之甚少。这意味着他们作为NICE研究人员的标准工具可能没有足够的信息来说明搜索过滤器如何在不同的主题、问题和数据库中执行。我们的建议是研究如何测量搜索过滤器的性能，以及哪些测量对研究人员最有用。我们还计划研究系统和方法，以便更好地访问有关方法学搜索过滤器的相关和有用的性能数据。这项研究的好处是增强了可用工具的工具和知识，以找到研究证据，为NICE评估、指导方针和其他指导提供信息。研究结果也将使其他国家技术评估机构、准则小组和有关机构受益。

NICE requires research to help it decide which treatments and diagnostic methods should be funded by the NHS. NICE has highlighted the need for research into the methods for reviewing evidence from research. Identifying research studies underpins most NICE reviewing. Methodological search filters are widely used to identify specific research designs such as randomized controlled trials or economic evaluations. Search filters are carefully selected collections of words and phrases used to search databases to identify research.Little is known about how well search filters work in finding research. This means that their use as a standard tool for NICE researchers may not be informed by adequate information to indicate how search filters perform across different subjects, questions and databases. Our proposal is to investigate how search filter performance can be measured and what measures are most useful to researchers. We also plan to investigate systems and approaches to provide better access to relevant and useful performance data on methodological search filters. The benefits of this research would be to enhance the tools and knowledge of the tools available to find research evidence to inform NICE appraisals, guidelines and other guidance. The research findings would also benefit other national technology assessment agencies, guidelines groups and related bodies.
