Abstract

Objectives: A significant proportion of healthcare workers (HCWs) had been infected with SARS-CoV-2, which complicated the organization of patient care during the COVID-19 pandemic. However, the exact scale of infection prevalence among the group of HCWs is not known, therefore this study aimed to assess the prevalence of SARS-CoV-2 infection among HCWs in the Silesian voivodeship, Poland, and to define its determinants.

Material and methods: The cross-sectional study was conducted in 2 multidisciplinary hospitals in the Silesian voivodeship during the period October 2021-February 2022. The standardized WHO questionnaire Surveillance protocol for SARS-CoV-2 infection among health workers was completed by 242 HCWs. To assess the prevalence of SARS-CoV-2 infection and its determinants, such as personal, occupational, and work environment-related conditions and preventive behaviors, the collected data were subjected to statistical analysis. For this purpose, descriptive and analytical statistics (significance of differences in χ² test) were used.

Results: Almost half (42.6%) of subjects were infected with coronavirus, most frequently care assistants (57.1%) and paramedics (50%). People suffering from chronic diseases were infected significantly more often (p < 0.001). The majority of the infected HCWs declared previous contact with COVID-19 patients (56.3%). Unfortunately, 10.3% of respondents refused to be vaccinated against COVID-19, most often care assistants (38.1%) and nurses (10.6%). The determinants such as sex, age, occupation, place of work (ward), participation in occupational safety and health training, use of personal protective equipment (PPE), or preventive behaviors did not significantly affect the risk of infection (p > 0.05).

Conclusions: Even though the PPE was used and the percentage of fully vaccinated HCWs against COVID-19 was high (89.7%), the frequency of SARS-CoV-2 infected HCWs remains high at 42.6% (95% CI: 40.7-44.5%). The main determinants of SARS-CoV-2 infection risk among HCWs were previous contact with infected individuals and the presence of chronic disease. Int J Occup Med Environ Health. 2023;36(2):201-13.

西里西亚省横断面研究的结果:卫生保健工作者中SARS-CoV-2感染的流行率和决定因素

目的:在COVID-19大流行期间，相当比例的医护人员感染了SARS-CoV-2，这使患者护理的组织复杂化。然而，卫生保健工作者群体中感染流行率的确切规模尚不清楚，因此本研究旨在评估波兰西里西亚省卫生保健工作者中SARS-CoV-2感染的流行率，并确定其决定因素。材料和方法:横断面研究于2021年10月至2022年2月期间在西里西亚省的2家多学科医院进行。242名卫生保健工作者完成了卫生工作者SARS-CoV-2感染标准世卫组织问卷监测方案。为了评估SARS-CoV-2感染的流行情况及其影响因素，如个人、职业和工作环境相关条件和预防行为，对收集的数据进行统计分析。为此，采用描述性统计和分析性统计(χ2检验差异显著性)。结果:近一半(42.6%)的受试者感染冠状病毒，最常见的是护理助理(57.1%)和护理人员(50%)。患有慢性疾病的人感染的频率明显更高(p < 0.001)。大多数受感染的医护人员报告曾与COVID-19患者有过接触(56.3%)。不幸的是，10.3%的受访者拒绝接种COVID-19疫苗，最常见的是护理助理(38.1%)和护士(10.6%)。性别、年龄、职业、工作场所(病房)、是否参加职业安全卫生培训、是否使用个人防护装备(PPE)、是否有预防行为等因素对感染风险无显著影响(p > 0.05)。结论:尽管使用了个人防护装备，并且充分接种COVID-19疫苗的卫生工作者比例很高(89.7%)，但卫生工作者感染SARS-CoV-2的频率仍然很高，为42.6% (95% CI: 40.7-44.5%)。卫生保健工作者中SARS-CoV-2感染风险的主要决定因素是与感染者的既往接触和是否存在慢性疾病。中华医学杂志，2009;36(2):201-13。
