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.
