Abstract：
BACKGROUND: Infection prevention and control (IPC) measures are crucial to combat the COVID-19 pandemic. This study aimed to explore the levels and determinants of HCWs\' IPC behaviors based on the theoretical domains framework (TDF), which has been shown to be effective in guiding behavior change.
METHODS: A cross-sectional survey was conducted in Wuhan, China in January 2020. Self-reported hand hygiene and droplet isolation behaviors (including the use of masks, gloves, goggles and gowns) were set as dependent variables. TDF domains and HCWs\' characteristics were independent variables. Negative binomial regression analyses were performed to explore their relationships.
RESULTS: HCWs reported good IPC behaviors, while the compliance with goggle and gown use was relatively low (below 85%). Environmental context and resources domain was significantly related to hand hygiene (β = 0.018, p = 0.026), overall droplet isolation behaviors (β = 0.056, p = 0.001), goggle (β = 0.098, p = 0.001) and gown use (β = 0.101. p < 0.001). Knowledge domain was significantly related to goggle (β = 0.081, p = 0.005) and gown use (β = 0.053, p = 0.013). Emotion domain was a predictor of overall droplet isolation behaviors (β = 0.043, p = 0.016), goggle (β = 0.074, p = 0.026) and gown use (β = 0.106, p < 0.001). Social influences domain was a predictor of overall droplet isolation behaviors (β = 0.031, p = 0.029) and gown use (β = 0.039, p = 0.035). HCWs in high-risk departments had better behaviors of gown use (β = 0.158, p = 0.032). HCWs who had encountered confirmed or suspected patients reported worse behaviors of goggle (β = - 0.127, p = 0.050) and gown use (β = - 0.153, p = 0.003).
CONCLUSIONS: Adequate personal protective materials and human resources, education and training, as well as supervision and role model setting are necessary to improve IPC behaviors regarding the COVID-19 pandemic.

摘要：
背景：感染预防和控制（IPC）措施对于抗击COVID-19大流行至关重要。本研究旨在基于理论领域框架(TDF)探索HCWsIPC行为的水平和决定因素，这已被证明在指导行为改变方面是有效的。
方法：在武汉市进行了横断面调查，2020年1月中国。自我报告的手卫生和液滴隔离行为（包括使用口罩，手套,护目镜和礼服)被设置为因变量。TDF域和HCWs的特征是自变量。进行负二项回归分析以探索它们的关系。
结果：HCWs报告了良好的IPC行为，而护目镜和礼服使用的依从性相对较低(低于85%)。环境背景和资源领域与手卫生显著相关(β=0.018，p=0.026)，整体液滴分离行为(β=0.056，p=0.001)，护目镜（β=0.098，p=0.001）和礼服使用（β=0.101。p<0.001)。知识领域与护目镜（β=0.081，p=0.005）和长袍使用（β=0.053，p=0.013）显着相关。情绪域是整体液滴分离行为的预测因子(β=0.043，p=0.016)，护目镜（β=0.074，p=0.026）和长袍使用（β=0.106，p<0.001）。社会影响域是整体液滴隔离行为（β=0.031，p=0.029）和长袍使用（β=0.039，p=0.035）的预测指标。高危科室的医护人员使用礼服的行为较好（β=0.158，p=0.032）。遇到确诊或疑似患者的HCWs报告了更差的护目镜行为（β=-0.127，p=0.050）和长袍使用行为（β=-0.153，p=0.003）。
结论：有足够的个人防护材料和人力资源，教育和培训,以及监督和榜样设置对于改善关于COVID-19大流行的IPC行为是必要的。
