Abstract：
The use of jewelry among healthcare professionals poses a risk of cross contamination due to potential bacterial accumulation and spread. Through a mixed-method design, this study first analyzed the implications of healthcare professionals wearing jewelry on patient care biosafety as well as on the residual bacterial load of hands and rings after hand hygiene. Firstly, an observational prevalence study to verify whether nursing professionals wear personal accessories during healthcare assistance was carried out. Second, an experimental design involving intentional contamination and hygiene of the hands, with and without a ring, was conducted. The bacterial load of both hands and rings was measured by counting colony forming units. The observational study showed that nursing workers frequently wear jewelry during healthcare assistance. Nonetheless, the experimental study did not indicate differences in bacterial contamination between hands with and without a ring, despite the hand hygiene procedure applied. In conclusion, many nursing workers wear jewelry in the workplace. Although hands with and without a ring exhibited similar microbial load, rings appeared as a potential source of bacterial contamination, reinforcing the need to remove jewelry during working hours. Hand hygiene using alcohol, or soap and water significantly decreased the bacterial load on the participants\' hands, with handwashing proving to be the most efficient method for removing intentional contamination.
摘要：
由于潜在的细菌积累和传播，在医疗保健专业人员中使用珠宝会带来交叉污染的风险。通过混合方法设计，这项研究首先分析了医疗保健专业人员佩戴珠宝对患者护理生物安全以及手部卫生后手部和戒指残留细菌负荷的影响。首先,我们进行了一项观察性患病率研究,以验证护理专业人员在医疗救助期间是否佩戴个人配饰.第二,涉及手的有意污染和卫生的实验设计，有和没有戒指，进行了。通过计数菌落形成单位来测量双手和戒指的细菌负荷。观察性研究表明，护理人员在医疗援助期间经常佩戴珠宝。尽管如此，实验研究没有表明有和没有戒指的手之间细菌污染的差异，尽管采用了手部卫生程序。总之,许多护理人员在工作场所佩戴珠宝。尽管有和没有戒指的手表现出相似的微生物负荷，环是细菌污染的潜在来源，加强在工作时间内移除珠宝的需要。使用酒精的手部卫生，或者肥皂和水显著减少了参与者手上的细菌负荷，洗手被证明是去除故意污染的最有效方法。
