Multicenter studies are becoming more common, and variability in local institutional review board (IRB) assessments can be problematic.
To investigate the variability of IRB responses to a multicenter observational study of children presenting to emergency departments.
The authors collected the original IRB applications, subsequent correspondence, and a survey assessing submission timing and response and the nature of IRB queries. The study was conducted as part of the Emergency Medicine Network (http://www.emnet-usa.org).
Of 37 sites initiating the IRB process, 34 (92%) participated in this IRB-approved study. Institutional review boards returned initial applications in a median of 19 days (IQR, 11-34 d), and 91% considered the protocol to be minimal risk. Of 34 submissions, 13 required no changes, 18 received conditional approvals, and 3 were deferred. The median time from initial submission to final approval was 42 days (IQR, 27-61 d). Seven sites did not participate in patient recruitment: two had institutional issues, one obtained IRB approval too late for participation, and four sites (12%) reported that IRB hurdles contributed to their lack of participation. Nonetheless, 68% of sites that recruited patients reported that the overall experience made them more likely to participate in future multicenter research.
There was substantial variation in IRB assessment of a standard protocol in this study. The burden of the application process contributed to some investigators not participating, but the majority of investigators remain enthusiastic about multicenter research. A national IRB may streamline the review process and facilitate multicenter clinical research.
多中心研究越来越普遍,而当地机构审查委员会(IRB)评估的变异性可能会带来问题。
调查IRB对一项针对急诊科儿童的多中心观察性研究的反应变异性。
作者收集了原始的IRB申请、后续通信以及一项评估提交时间、回复情况和IRB询问性质的调查。该研究是作为急诊医学网络(http://www.emnet-usa.org)的一部分进行的。
在启动IRB程序的37个机构中,34个(92%)参与了这项经IRB批准的研究。机构审查委员会在中位数为19天(四分位间距,11 - 34天)内返回了初始申请,91%认为该方案风险极小。在34份提交的申请中,13份无需修改,18份获得有条件批准,3份被推迟。从初始提交到最终批准的中位时间为42天(四分位间距,27 - 61天)。7个机构未参与患者招募:2个存在机构问题,1个获得IRB批准时已太晚无法参与,4个机构(12%)报告称IRB的障碍导致他们未能参与。尽管如此,68%招募了患者的机构表示,总体经历使他们更有可能参与未来的多中心研究。
在本研究中,IRB对标准方案的评估存在很大差异。申请过程的负担导致一些研究者未参与,但大多数研究者仍对多中心研究充满热情。一个全国性的IRB可能会简化审查过程并促进多中心临床研究。
