Background: 

An external ventricular drain (EVD) training module may improve the knowledge and proficiency of perioperative health care providers (HCPs).

Methods: 

We examined knowledge gaps, self-reported comfort in managing EVDs, and improvement in self-assessment scores among HCPs from 7 academic medical centers based on an online EVD training module.

Results: 

Of the 326 HCPs who completed the module, 207 (70.6%) reported being uncomfortable managing EVDs. The median pretest scores were 6 (interquartile range=2), and posttest scores were 8 (interquartile range=1), out of a maximum possible score of 9. The most frequent incorrectly answered questions were: (a) maximum allowed hourly cerebrospinal fluid volume drainage (51%), (b) the components of a normal intracranial pressure waveform (41%), and (c) identifying the correct position of the stopcock for accurate measurement of intracranial pressure (41%). The overall gain in scores was 2 (interquartile range=2) and highest among HCPs who had managed 1 to 25 EVDs (2.51, 95% confidence interval: 2.23-2.80), and without self-reported comfort in managing EVDs (2.26, 95% confidence interval: 1.96-2.33, P<0.0001). The majority of participants (312, 95.7%) reported that the training module helped them understand how to manage EVDs, and 276 (84.7%) rated the module 8 or more out of 10 in recommending it to their colleagues.

Conclusions: 

This online EVD training module was well-received by participants. Overall, improved scores reflect enhanced knowledge among HCPs following completion of the module. The greatest benefit was observed in those reporting less experience and feeling uncomfortable in managing EVDs. The impact on the reduction in EVD-associated adverse events deserves further examination.

实施在线心室外引流培训模块——一项提高围手术期医疗保健提供者熟练程度的教育举措：回顾性研究结果

背景： 

心室外引流 (EVD)培训模块可以提高围手术期医疗保健提供者 (HCP) 的知识和熟练程度。

方法： 

我们基于在线 EVD 培训模块，检查了来自 7 个学术医疗中心的 HCP 的知识差距、自我报告的管理 EVD 的舒适度以及自我评估分数的提高。

结果： 

在完成该模块的 326 名 HCP 中，207 名 (70.6%) 表示对管理埃博拉病毒病感到不舒服。预测分数中位数为 6（四分位距 = 2），后测分数为 8（四分位距 = 1），最大可能分数为 9。 最常见的错误回答问题是： (a) 每小时允许的最大脑脊液量容量引流（51%），（b）正常颅内压波形的组成部分（41%），以及（c）确定旋塞阀的正确位置以准确测量颅内压（41%）。分数的总体增益为 2（四分位距 = 2），在管理过 1 至 25 例埃博拉病毒病的 HCP 中得分最高（2.51，95% 置信区间：2.23-2.80），并且在管理埃博拉病毒病方面没有自我报告的舒适度（2.26，95） % 置信区间：1.96-2.33，P <0.0001）。大多数参与者 (312 名，95.7%) 表示，该培训模块帮助他们了解如何管理 EVD，276 名参与者 (84.7%) 向同事推荐该模块，评分为 8 分或以上（满分 10 分）。

结论： 

此次在线EVD培训模块受到了参与者的好评。总体而言，分数的提高反映了完成该模块后 HCP 知识的增强。最大的好处是那些报告经验较少并且在管理 EVD 方面感到不舒服的人。对减少埃博拉病毒病相关不良事件的影响值得进一步研究。
