Background Medical devices are a crucial component in the field of radiation oncology. The review and licensing of radiation oncology devices (RODs) is managed on a national basis in Canada by Health Canada and in the United States by the Food and Drug Administration (FDA). The purpose of this study was to examine differences in ROD licensing timelines between Health Canada and the FDA that may impact the ability of Canadians to access the most up-to-date radiation oncology care. Methods A list of ROD was compiled by searching keywords, manufacturers, and proprietary device names in the publicly accessible Canadian Medical Devices Active Licence Listing (MDALL) and the American Establishment Registration & Device Listing and the 510(k) Premarket Notification database. ROD licensing dates were then obtained through both databases. ROD were included if they were licensed in both countries. Results A total of 51 RODs were included in this study and it was found that 71% (36/51) were issued licenses for sale in the United States before Canada, at a mean of 506 days sooner (median [IQR] = 282 [326.5]). No trends in licensing dates were found by stratifying devices by type. Analyses were limited to the date of licensing only, as Health Canada provided no publicly-available information regarding submission milestones such as first submission date for the RODs studied. Conclusions The majority of radiation oncology devices examined were licensed for sale in the USA before Canada. Due to the absence of publicly available information regarding initial ROD application date, we cannot evaluate the impact of the approval process on the overall difference in licensing date. Importantly, this research highlights a lack of publicly-available information from Health Canada regarding the medical device approval process for the radiation oncology devices studied herein.
背景 医疗设备是放射肿瘤学领域的关键组成部分。在加拿大,放射肿瘤学设备(ROD)的审查和许可由加拿大卫生部在国家层面进行管理;在美国,则由食品药品监督管理局(FDA)负责。本研究的目的是考察加拿大卫生部和FDA在ROD许可时间线上的差异,这些差异可能会影响加拿大人获得最新放射肿瘤治疗的能力。方法 通过在公开可获取的加拿大医疗器械有效许可证清单(MDALL)、美国机构注册与设备清单以及510(k)上市前通知数据库中搜索关键词、制造商和专有设备名称,编制了一份ROD清单。然后通过这两个数据库获取ROD的许可日期。若ROD在两国均获得许可,则纳入研究。结果 本研究共纳入51种ROD,发现71%(36/)在美国获得销售许可的时间早于加拿大,平均早506天(中位数[四分位间距]=282[326.5])。按设备类型分层未发现许可日期的趋势。分析仅限于许可日期,因为加拿大卫生部未提供有关提交里程碑(如所研究ROD的首次提交日期)的公开信息。结论 所考察的大多数放射肿瘤学设备在美国获得销售许可的时间早于加拿大。由于缺乏关于ROD初始申请日期的公开信息,我们无法评估审批过程对许可日期总体差异的影响。重要的是,本研究凸显了加拿大卫生部缺乏关于本文所研究放射肿瘤学设备医疗器械审批过程的公开信息。
