Ensuring safety and availability of healthcare workers in the era of COVID-19: An experience from the Eastern State of India

摘要

Objectives: The objective of this study was to design a contact tracing algorithm and contact investigation form for healthcare workers deployed in rendering essential health-care services in limitedly resourced healthcare settings during the COVID era. Material and Methods: It was an observational study, longitudinal in design. Based on the existing evidence as of April 15, 2020, we have designed a contact tracing algorithm and contact investigation form to determine the risk of infection among healthcare workers. Later, we have tested the developed contact tracing algorithm and contact investigation from among 28 suspected contacts of a confirmed COVID-19 case admitted in all India Institute of Medical Sciences Patna, Bihar, India. Results: Using the designed contact investigation form, all the 28 suspected contacts of the confirmed COVID-19 case were interviewed, among which only 7(25%) were found to be having high-risk exposure. All persons with high-risk exposure were home quarantined for 5 days, along with their direct contacts. Eventually, all high-risk contacts were tested negative on the 5 th day after exposure and immediately joined their duties after that. Those who were at low risk of infection continued to work and self-monitor for COVID compatible symptoms for 14 days. Eventually, none of the low-risk exposure persons developed COVID compatible symptoms, therefore deferred testing. Conclusion: The contact tracing approach designed in the current study is a balanced one where we tried to balance health workers safety without compromising their availability for duty. This approach can also be implemented in other healthcare settings in the era of COVID-19.
