While healthcare workers (HCWs) are at risk of occupational exposure to SARS-CoV-2 infection, the virus transmission involving them might be exceeding in the non-occupational settings. This study examined the extent of adherence to infection prevention practices (IPPs) against COVID-19 in their daily life and its associated factors among staff members in a national medical center designated for COVID-19 treatment in Tokyo, Japan.
This cross-sectional study was conducted in July 2020 among 1,228 staff of National Center for Global Health and Medicine (NCGM). We asked participants about their adherence on six IPPs recommended by the WHO in their daily lives, which included wearing masks, maintaining hand and respiratory hygiene, avoiding 3Cs and social distancing. We defined 100% adherence (6 points) to IPPs as good adherence and run logistic regression model to estimate odds ratios (ORs) and 95% confidence intervals (CIs) of IPPs.
Nearly 100% of NCGM staff members adhered to four out of six IPPs assessed in this study: washing or sanitizing hands (99.6%), good cough etiquette (99.6%), wearing mask (98.9%), and avoiding 3Cs (98.3%). Doctors (AOR = 2.18, CI: 1.36-3.49) and female staff members (AOR = 1.95, CI: 1.36-3.49) were more likely to adhere to IPPs compared with non-clinical staffs and male counterparts. Good adherence to IPPs tended to increase with older age, with highest adherence among those who were 50 years or above (AOR = 2.53, CI: 1.49-4.29).
This study revealed that the IPPs among NCGM staff was remarkably good. Older and female staff members, and doctors showed a higher adhere to IPPs compared with their counterparts. Additional effort to improve adherence to IPPs among the younger and male staff members could contribute to reduce infection risk in their daily life, which can eventually prevent nosocomial infection.
医护人员（HCWs）面临职业暴露于 SARS-CoV-2 感染的风险，但在非职业环境中，病毒传播可能会超过他们。本研究检查了在日本东京一家专门治疗 COVID-19 的国立医疗中心，工作人员在日常生活中对 COVID-19 感染预防措施（IPPs）的遵守程度及其相关因素。
本横断面研究于 2020 年 7 月在国立全球卫生与医学中心（NCGM）的 1228 名工作人员中进行。我们询问了参与者在日常生活中遵守世界卫生组织推荐的六项 IPPs 的情况，包括戴口罩、保持手和呼吸道卫生、避免 3C 和保持社交距离。我们将 IPPs 的 100%（6 分）遵守定义为良好的遵守，并运行逻辑回归模型来估计 IPPs 的优势比（OR）和 95%置信区间（CI）。
NCGM 工作人员几乎 100%遵守了本研究评估的六项 IPPs 中的四项：洗手或消毒（99.6%）、良好的咳嗽礼仪（99.6%）、戴口罩（98.9%）和避免 3C（98.3%）。与非临床人员和男性同行相比，医生（AOR=2.18，CI：1.36-3.49）和女性工作人员（AOR=1.95，CI：1.36-3.49）更有可能遵守 IPPs。良好的 IPPs 遵守情况随着年龄的增长而增加，其中 50 岁或以上的人群的遵守程度最高（AOR=2.53，CI：1.49-4.29）。
本研究表明，NCGM 工作人员的 IPPs 非常好。与同龄人相比，年龄较大和女性工作人员以及医生更倾向于遵守 IPPs。加强对年轻和男性工作人员遵守 IPPs 的努力，有助于降低他们日常生活中的感染风险，最终可预防医院感染。
