The aim of this study was to identify and rank the sources for the detection of potentially obsolete technologies (POTs).
A specific questionnaire related to the search strategies and sources used for the identification of POTs and also for ineffective, inefficient or harmful health technologies was sent to the Health Technology Assessment International's Information Resources Group (HTAi-IRG) group. With the obtained information and taking into account the sources used for the identification of new and emerging technologies, a second questionnaire was elaborated and sent to EuroScan and International Network of Agencies for Health Technology Assessment (INAHTA) members, who had to select and score them. For the final ranking, the number of votes and the median score were taken into account.
Seven HTAi-IRG members answered to the first questionnaire. Seventeen agencies answered to the second one (thirteen EuroScan members and four more members from INAHTA), but only seven had worked in the identification of POTs and one of them using only experts for it. The remaining six agencies answered the part related to devices, diagnostics, and procedures; five of them did it for settings and programmes and only three for drugs. The Canadian Agency for Drugs and Technologies in Health (5 votes; median = 2), Cochrane Collaboration (5 votes; median = 3), NICE (4 votes; median = 1), Food and Drug Administration (4 votes; median = 1.5), and EuroScan (4 votes, median = 2) were the most relevant sources for devices and diagnostics.
There is little experience on POTs identification. The identified sources provide mostly indirect information and further research should take place to determine the best use of them.
本研究旨在识别潜在过时技术（POTs）的检测来源并进行排名。
向国际卫生技术评估信息资源小组（HTAi-IRG）发送了一份特定问卷，该问卷涉及用于识别POTs以及无效、低效或有害健康技术的搜索策略和来源。利用获得的信息，并考虑到用于识别新兴技术的来源，编制了第二份问卷并发送给欧洲卫生技术信息数据库（EuroScan）和国际卫生技术评估机构网络（INAHTA）的成员，他们必须对这些来源进行选择和评分。对于最终排名，考虑了投票数和中位数得分。
7名HTAi-IRG成员回答了第一份问卷。17个机构回答了第二份问卷（13个EuroScan成员和4个INAHTA成员），但只有7个机构从事过POTs的识别工作，其中1个机构仅使用专家进行识别。其余6个机构回答了与设备、诊断和程序相关的部分；其中5个机构回答了与环境和项目相关的部分，只有3个机构回答了与药物相关的部分。加拿大卫生药品和技术局（5票；中位数=2）、考克兰协作网（5票；中位数=3）、英国国家卫生与临床优化研究所（4票；中位数=1）、美国食品药品监督管理局（4票；中位数=1.5）和EuroScan（4票，中位数=2）是设备和诊断方面最相关的来源。
在识别POTs方面经验很少。所识别的来源大多提供间接信息，应进一步开展研究以确定其最佳用途。
