Abstract

Background

During the Covid-19 pandemic, the protection of healthcare workers has been in focus throughout the world, but the availability and quality of personal protective equipment has at times and in some settings been suboptimal.

Materials and methods

A total of 8679 healthcare workers and healthcare support staff in the county of Uppsala, north of Stockholm, were included in this cross-sectional study. All subjects were analysed for IgG anti-SARS-CoV-2, and predictors for positive serostatus were analysed in a logistic regression model including demographic parameters and self-reported employment characteristics.

Results

Overall, 577 (6.6%) were classified as seropositive, with no statistically significant differences between healthcare workers and support staff. Among healthcare workers, age (OR 0.987 per year, 95% CI 0.980–0.995), time to sampling (OR 1.019 per day, 95% CI 1.004–1.035), and employment at an outpatient care unit (OR 0.620, 95% CI 0.487–0.788) were statistically significantly associated with risk of infection. Covid-19 specific units were not at particular risk, compared to other units with comparable characteristics and staff demography.

Conclusion

Our findings indicate that SARS-CoV-2 transmission is related to inpatient healthcare work, and illustrate the need for a high standard of basic hygiene routines in all inpatient care settings.

住院部门的工作与SARS-CoV-2感染的风险增加有关；对瑞典8679名医护人员的横断面研究。

摘要

背景

在Covid-19大流行期间，保护医护人员一直是全世界关注的重点，但是个人防护设备的可用性和质量有时甚至在某些情况下都不理想。

材料和方法

这项横断面研究包括斯德哥尔摩北部乌普萨拉县的8679名医护人员和医护人员。分析所有受试者的IgG抗SARS-CoV-2抗体，并在包括人口统计学参数和自我报告的就业特征的逻辑回归模型中分析阳性血清状况的预测因子。

结果

总体上，有577名（6.6％）被归类为血清反应阳性，医护人员和支持人员之间无统计学差异。在医护人员中，年龄（OR 0.987 /年，95％CI 0.980-0.995），采样时间（OR 1.019 /日，95％CI 1.004-1.035）和门诊工作（OR 0.620，95％CI） 0.487-0.788）与感染风险有统计学意义。与具有类似特征和人员人口统计的其他部门相比，Covid-19特定部门没有特别的风险。

结论

我们的发现表明，SARS-CoV-2的传播与住院医疗工作有关，并且说明了在所有住院医疗机构中都需要高标准的基本卫生程序。
