(1) Background: Numerous educational interventions have been conducted to improve hand hygiene (HH) compliance and effectiveness among nursing students, with mixed results. The aim is to evaluate the effectiveness of posters as a teaching tool and factors associated with HH quality. (2) Methods: A pre-post experimental intervention study was conducted with a total of 293 nursing students randomly assigned to two groups (experimental and control) who, before and after HH, took cell culture samples from their non-dominant hands. Only the experimental group was exposed to the poster. (3) Results: In the experimental group, significant differences were observed among students older than 22 years ( = 0.017; V = 0.188), with a higher percentage of failures (15.7% vs. 3.6%). Poster displaying was associated with passing, other variables being equal, although without statistical significance (ORa = 2.07; 95% CI = 0.81-5.26). Pre-practice hand contamination was weakly associated with lower HH quality (ORa = 0.99, 95% CI = 0.99-0.99). (4) Conclusions: The use of posters as a teaching method shows indications of efficacy. Prior hand contamination slightly affects the quality of HH. Further evaluation of teaching methods is needed to ensure good technical performance of HH to prevent the spread of infectious diseases during the COVID-19 pandemic.
(1) 背景：为了提高护理学生的手卫生（HH）依从性和效果，已经进行了许多教育干预措施，但结果喜忧参半。本研究旨在评估海报作为教学工具的效果，以及与 HH 质量相关的因素。
(2) 方法：采用前后实验干预研究，共 293 名护理学生被随机分为两组（实验组和对照组），在 HH 前后，从非优势手采集细胞培养样本。仅实验组接触海报。
(3) 结果：在实验组中，22 岁以上的学生差异显著（ = 0.017；V = 0.188），失败率更高（15.7%比 3.6%）。海报展示与通过考试有关，其他变量相等，尽管没有统计学意义（ORa = 2.07；95%CI = 0.81-5.26）。练习前手部污染与 HH 质量较低呈弱相关（ORa = 0.99，95%CI = 0.99-0.99）。
(4) 结论：海报作为一种教学方法显示出一定的效果。手部污染会略微影响 HH 的质量。需要进一步评估教学方法，以确保良好的 HH 技术性能，防止 COVID-19 大流行期间传染病的传播。
