The Impact of Social Factors on COVID-19 Risk among Healthcare Workers

A recent study published in Infection Control & Hospital Epidemiology has found that where healthcare workers live, as well as other social factors, can contribute to their risk of contracting COVID-19. The study, led by Maria Zlotorzynska, PhD, a health scientist with the Centers for Disease Control and Prevention, aimed to examine the relationship between healthcare workers’ residential areas and their vulnerability to COVID-19, as well as understand the reasons behind any disparities. The research team collected data from healthcare workers in Colorado, Minnesota, New Mexico, New York, and Oregon, encompassing various healthcare settings such as nursing homes, acute care hospitals, and outpatient clinics.

Participants in the study included both COVID-19 positive and negative healthcare workers, and data was collected from May to December 2020. The researchers used a measure called the Social Vulnerability Index (SVI) to classify the details of each participant. This index allowed them to assess the social vulnerability present in their residential areas, taking into account factors such as poverty levels, unemployment rates, the presence of older adults, children, and single-parent households.

The findings revealed that healthcare workers with COVID-19 had a higher likelihood of living in highly vulnerable census areas. Factors such as poverty, unemployment, and a higher concentration of older adults, children, and single-parent households in the residential areas were associated with an increased risk of COVID-19 infection among healthcare workers. This suggests that social factors beyond the workplace play a significant role in determining infection risk.

Dr. Zlotorzynska emphasized the importance of healthcare systems considering the social and economic contexts in which their staff members live. By recognizing the varied social factors that can influence infection risk, healthcare systems can better address labor shortages, improve workers’ well-being, and implement effective measures to reduce COVID-19 transmission. It is crucial for healthcare organizations to prioritize the development of strategies that take into account the social vulnerabilities of their workforce to ensure a safe and supportive environment for all healthcare workers.
