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.
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 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 χ test) were used.
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).
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.
相当比例的医护人员（HCWs）感染了 SARS-CoV-2，这使得 COVID-19 大流行期间的患者护理组织变得复杂。然而，尚不清楚医护人员群体中感染的具体比例，因此本研究旨在评估波兰西里西亚省医护人员中 SARS-CoV-2 感染的流行率，并确定其决定因素。
这项横断面研究于 2021 年 10 月至 2022 年 2 月在西里西亚省的 2 家多学科医院进行。242 名医护人员完成了世界卫生组织标准化问卷。为了评估 SARS-CoV-2 感染及其决定因素，例如个人、职业和工作环境相关条件以及预防行为，对收集到的数据进行了统计分析。为此，使用了描述性和分析性统计（卡方检验的差异显著性）。
近一半（42.6%）的研究对象感染了冠状病毒，其中护理助理（57.1%）和急救人员（50%）最为常见。患有慢性病的人感染的风险显著更高（p < 0.001）。大多数感染的医护人员报告曾接触过 COVID-19 患者（56.3%）。不幸的是，10.3%的受访者拒绝接种 COVID-19 疫苗，其中大多数是护理助理（38.1%）和护士（10.6%）。性别、年龄、职业、工作地点（病房）、参加职业安全与健康培训、使用个人防护设备（PPE）或预防行为等决定因素并未显著影响感染风险（p > 0.05）。
尽管医护人员使用了个人防护设备，且完全接种 COVID-19 疫苗的医护人员比例很高（89.7%），但 SARS-CoV-2 感染的医护人员比例仍高达 42.6%（95%CI：40.7-44.5%）。医护人员感染 SARS-CoV-2 的主要决定因素是曾接触过感染个体和患有慢性病。国际职业医学与环境卫生杂志。2023;36(2):201-23。
