Abstract

Introduction

The International Network of Agencies for Health Technology Assessment (INAHTA) database offers a single point of access for identifying technology appraisals, in contrast to searching multiple websites directly. The aim of this research is to compare the coverage of the INAHTA and Centre for Reviews and Dissemination (CRD) Health Technology Assessment (HTA) databases with direct searching on the National Institute for Health and Care Excellence (NICE) website to identify Technology Appraisals published by NICE.

Methods

NICE Technology Appraisals were downloaded from the NICE website (April 2022). Technology Appraisals were randomized and the first 20 Technology Appraisals constituted data for analysis. The INAHTA and CRD HTA databases were searched to determine if the 20 Technology Appraisals available on the NICE website were also available for retrieval.

Results

Coverage was incomplete. INAHTA: 15 of 20 Technology Appraisals (75%) were not identified via full title or intervention-specific searches. CRD HTA: 7 of 12 Technology Appraisals (58%) that were published before the last update of the database were not identified.

Conclusion

Findings indicate that researchers seeking to identify NICE Technology Appraisals should search the NICE website directly. How this finding impacts identification of guidance from other agencies should be evaluated.

国际HTA数据库返回了NICE技术评估的不完整搜索结果:一项探索性研究和影响的讨论

国际卫生技术评估机构网络(INAHTA)数据库提供了识别技术评估的单一访问点，而不是直接搜索多个网站。本研究的目的是比较INAHTA和审查与传播中心(CRD)卫生技术评估(HTA)数据库的覆盖范围，以及直接搜索国家卫生与护理卓越研究所(NICE)网站以识别NICE发布的技术评估。方法从NICE网站(2022年4月)下载NICE技术评价。随机选取前20份技术评价作为分析数据。检索INAHTA和CRD HTA数据库，以确定NICE网站上提供的20项技术评估是否也可用于检索。结果覆盖不完整。INAHTA: 20个技术评价中有15个(75%)没有通过完整的标题或特定干预措施的搜索来确定。CRD HTA:在数据库最后一次更新之前发布的12项技术评估中有7项(58%)未被确定。研究结果表明，寻求NICE技术评价的研究人员应直接搜索NICE网站。应该评估这一发现对确定其他机构的指导有何影响。
