Abstract

BACKGROUND

Acrylic nails harbor more bacteria than natural nails, and wear is not recommended for health care workers (HCWs). Little is known about the new and popular gel nail products. This study sought to evaluate the bacterial burden of gel nails, standard nail polish, and natural nails on the hands of HCWs.

METHODS

The study was conducted at 3 health centers. Nails on the dominant hand of 88 HCWs were painted with gel polish and standard polish. Cultures were obtained on days 1, 7, and 14 of wear and before and after hand hygiene with alcohol hand gel.

RESULTS

A total of 741 cultures were obtained. Bacterial burden increased over time for all nail types (P ≤ .0001). Reductions in the bacterial burden of natural nails and standard polish, but not gel polish, (P = .001, P = .0028, and P = .98, respectively) were seen after hand hygiene. All 3 nail types become more contaminated with bacteria over time. Standard polish and natural nails may be more amenable to hand hygiene than gel polish.

CONCLUSIONS

This study did not show an increased number of microorganisms on nails with gel polish; however, gel nails may be more difficult to clean using alcohol hand gel.

摘要

背景

相较于天然指甲，美甲所使用的丙烯酸树脂会藏匿更多的细菌，因此并不建议医护人员（HCWs）美甲。而对于新兴的、流行的美甲胶产品，我们知之甚少。本研究旨在评估美甲胶、标准指甲油和 HCWs 手上天然指甲的细菌负担。

方法

该研究在 3 家健康中心进行。用凝胶指甲油和标准指甲油涂 HCWs 优势手的指甲。在佩戴的第 1、7 和 14 天以及在使用酒精手部凝胶进行手部卫生前后，分别获得培养物。

结果

共获得 741 个培养物。所有指甲类型的细菌负担随时间推移而增加（P ≤ .0001）。在进行手部卫生后，天然指甲和标准指甲油的细菌负担减少（P = .001、P =.0028 和 P =.98），但凝胶指甲油的细菌负担没有减少。所有 3 种指甲类型的细菌污染都会随时间推移而增加。与凝胶指甲油相比，标准指甲油和天然指甲可能更容易通过酒精手部凝胶清洁。
