OBJECTIVE
Visual estimation of blood loss has been shown to be inaccurate. The objective of this study was to evaluate the impact of a didactic training program on the accuracy of the estimation of blood loss and to compare the effectiveness of training provided by a web-based vs live session.
STUDY DESIGN
Multidisciplinary labor and delivery unit personnel participated in live or web-based training. Both sessions comprised a 5-station pretest and posttest. The primary outcome was the accuracy of estimated blood loss in the pretest compared with the posttest with the use of the Mann-Whitney U test.
RESULTS
Among 372 providers, the median improvement between pre- and posttest results was 34% (95% confidence interval, 10-57%; P < .001). This improvement did not differ significantly between the live sessions and web-based sessions (4%; 95% confidence interval, -10% to 12%).
CONCLUSION
Our study supports the use of live or web-based training to improve blood loss estimation accuracy.
目的
已证实，肉眼估计失血量并不准确。本研究旨在评估教学培训计划对失血量估计准确性的影响，并比较基于网络与现场培训的效果。
研究设计
多学科分娩单位人员参加现场或基于网络的培训。两个培训课程均包含 5 个站点的预测试和后测试。主要结局是使用曼-惠特尼 U 检验比较预测试和后测试中估计失血量的准确性。
结果
在 372 名提供者中，预测试和后测试结果的中位数改善为 34%（95%置信区间，10%-57%；P<.001）。现场培训与基于网络培训之间的这种改善没有显著差异（4%；95%置信区间，-10%至 12%）。
结论
我们的研究支持使用现场或基于网络的培训来提高失血量估计的准确性。
