A Semi-Quantitative Risk Assessment and Management Strategies on COVID-19 Infection to Outpatient Health Care Workers in the Post-Pandemic Period

Abstract

Background In the pandemic of COVID-19, due to asymptomatic patients and high personnel fluidity in outpatient clinics, health care workers (HCWs) in outpatients were facing severe threat from infection. There is an urgent need for a risk assessment to recognize and prevent infection risks. Purpose To establish a semi-quantitative risk assessment model on COVID-19 infections for HCWs in outpatient departments, and apply it to practices. Further to provide infection risk management strategies to reduce infection threats in the post-pandemic of COVID-19. Methods We used the method of Brainstorm, Literature study and Analytic Hierarchy Process (AHP) for risk factors selection and model construction, we also created corresponding indicators for each risk factors, in order to collect data in assessment practice. Results Eighteen risk factors were recognized and selected for model construction, by scatter plot, these risk factors had been classified into four parts, spanned the scopes of diagnosis and treatment, environment, personal protection and emergency handling, with specific management suggestions provided. In the practice, outpatient clinics were divided into three risk levels, 5 clinics in high risk level, 9 in medium risk level and 11 in low risk level. Conclusion A proper comprehensive risk assessment model for COVID-19 infections has been successfully established. With the model, the ability to COVID-19 prevention in outpatients can be easily evaluated. The strategies on disinfection, surveillance and personal protection were also valuable references in the post-pandemic of COVID-19.

“…Inspired by Aydin et al ( 2020a ), Hoeher et al ( 2021 ) reproducibly took into account gravity and air drag. Similarly, our previous article (Aydin et al, 2020a ) was included in a meta-analysis of 35 publications selected by an expert panel in order to decide risk factors to establish a semi-quantitative assessment of COVID-19 infections (Wang et al, 2021 ).…”

“…The floor and wall should be cleaned with chlorine-containing disinfectant first. Use 1,000 mg/L to disinfect 3 times a day, each action is 30 min, and it will be disinfected at any time if it is contaminated; the contaminated area should be disinfected 3 times a day, and the action is 30 min ( 14 – 16 ).…”

The mobile phones of medical staff should be wiped frequently with 75% ethanol disinfectant, at least once a day ( 14 – 16 ).…”
