News media are used for community education and notification in exception from informed consent clinical trials, yet their effectiveness as an added safeguard in such research remains unknown. We assessed the number of callers requesting opt-out bracelets after each local media report and described the errors and content within each media report.
We undertook a descriptive analysis of local media trial coverage (newspaper, television, radio, and Web log) and opt-out requests during a 41-month period at a single site participating in an exception from informed consent out-of-hospital trial. Two nontrial investigators independently assessed 41 content-based media variables (including background, trial information, graphics, errors, publication information, and assessment) with a standardized, semiqualitative data collection tool. Major errors were considered serious misrepresentation of the trial purpose or protocol, whereas minor errors included misinformation unlikely to mislead the lay reader about the trial. We plotted the temporal relationship between opt-out bracelet requests and media reports. Descriptive information about the news sources and the trial coverage are presented.
We collected 39 trial-related media reports (33 newspaper, 1 television, 1 radio, and 4 blogs). There were 13 errors in 9 (23%) publications, 7 of which were major and 6 minor. Of 384 requests for 710 bracelets, 310 requests (80%) occurred within 4 days after trial media coverage. Graphic timeline representation of the data suggested a close association between media reports about the trial and requests for opt-out bracelets.
According to results from a single site, local media coverage for an exception from informed consent clinical trial had a substantial portion of errors and appeared closely associated with opt-out requests.
新闻媒体用于在临床试验中获得知情同意的豁免情况下进行社区教育和通知,但它们在这种研究中作为附加保障的有效性尚不清楚。我们评估了在单个站点参与一项豁免知情同意的院外试验期间,每次当地媒体报道后要求退出手环的呼叫者人数,并描述了每个媒体报道中的错误和内容。
我们对当地媒体试验报道(报纸、电视、广播和网络日志)和在单一站点参与一项豁免知情同意的院外试验的 41 个月期间的退出请求进行了描述性分析。两名非试验调查员使用标准化的半定性数据收集工具,对 41 个基于内容的媒体变量(包括背景、试验信息、图形、错误、出版信息和评估)进行了独立评估。主要错误被认为是对试验目的或方案的严重歪曲,而次要错误包括不太可能误导普通读者了解试验的错误信息。我们绘制了退出手环请求与媒体报道之间的时间关系。提供了有关新闻来源和试验报道的描述性信息。
我们收集了 39 份与试验相关的媒体报道(33 份报纸、1 份电视、1 份广播和 4 份博客)。在 9 份出版物(23%)中发现了 13 个错误,其中 7 个是主要错误,6 个是次要错误。在 384 份对 710 个手环的请求中,310 份请求(80%)发生在试验媒体报道后的 4 天内。数据的图形时间线表示法表明,试验的媒体报道与退出请求之间存在密切关联。
根据单个站点的结果,豁免知情同意的临床试验的当地媒体报道存在相当一部分错误,并且似乎与退出请求密切相关。
