The purpose of this study was to determine whether use of a video camera surveillance system for hand hygiene (HH) monitoring, video-based education, and feedback could improve the HH compliance in a neonatal intensive care unit (NICU).
This was an interventional before-after trial conducted in a level-III NICU between July 2019 and June 2020. HH compliance was measured using randomly selected video-camera footage in the baseline, intervention, and maintenance periods. After the baseline, an intervention consisting of feedback and education with video scenarios was implemented. The primary outcome was change in HH compliance. The compliance rates were analyzed as an interrupted time series (ITS) with a segmented regression model adjusted for autocorrelation for each study period.
We identified a total of 8335 HH indications. There were non significant increases in the total compliance rate (9.0%, 95% CI -2% to 20%) at the time of intervention and in the compliance rate after intervention (0.26%, 95% CI -0.31% to 0.84%) per day. The hand hygiene compliance before patient contact significantly increased (19.8%, 95% CI, 4.8%-34.8%). Incorrect glove use improved non-significantly with the intervention (-3.4%, 95% CI -13.4% to 6.7%).
In this study of HH monitoring using video-camera footage combined with an intervention including feedback and education, there were inconsistent improvements in HH compliance. However, these improvements were not sustained in the long term. Frequent feedback and education may be required to sustain high compliance.
本研究旨在确定使用摄像机的手卫生(HH)监测、基于视频的教育和反馈系统是否能够提高新生儿重症监护病房(NICU)的 HH 依从性。
这是一项在 2019 年 7 月至 2020 年 6 月期间在三级 NICU 进行的干预前后试验。在基线、干预和维持期使用随机选择的摄像机录像来测量 HH 依从性。基线后,实施了一项包括反馈和基于视频场景的教育的干预措施。主要结果是 HH 依从性的变化。使用分段回归模型调整了每个研究期的自相关,对依从率进行了中断时间序列(ITS)分析。
我们共识别出 8335 次 HH 指征。干预时总依从率(9.0%,95%CI-2%至 20%)和干预后依从率(每天 0.26%,95%CI-0.31%至 0.84%)均有非显著增加。接触患者前的 HH 依从率显著增加(19.8%,95%CI,4.8%-34.8%)。干预后不正确戴手套的情况虽有非显著改善(-3.4%,95%CI-13.4%至 6.7%)。
在这项使用摄像机录像进行 HH 监测并结合包括反馈和教育的干预措施的研究中,HH 依从性的改善不一致。然而,这些改善并没有在长期内持续。可能需要频繁的反馈和教育来维持高依从率。
