Abstract

Introduction: Healthcare workers have an increased risk of COVID- 19 infection either
due to their contact with infectious known cases, or due to exposure to subclinical or
undiagnosed patients. In cases of mild to moderate pneumonia, the pulmonary function
tests (PFTs) should be carried out following abnormal chest x-rays. Aim of Work: To
evaluate the respiratory impairment in healthcare workers after COVID-19 infection
using chest X-ray and pulmonary function tests in relation to their age and disease
duration. Materials and Methods: The study included 87 healthcare workers at El-
Nasr Hospital for Health Insurance, Helwan, Cairo. They all had recovered from a
proved COVID-19 infection 3 months at least prior to the assessment. The studied
group was subjected to full medical and occupational history taking, plain chest X-ray,
pulmonary function testing and Whole Person Impairment (WPI) rating using American
Medical Association Guides, 5th Edition, 2000. Results: the mean age of the studied
group was 41.26 years, most of them were females (87.3%) and 52.9% were nurses,
88.5% had respiratory impairment. X-Ray findings were detected in 94.2%, mainly
in the form of reticulonodular opacities (58%), most commonly affecting both lungs
(95.1%), mainly the basal parts (51%). The mean FVC of the studied group is 64.12%
of predicted indicating moderate restrictive ventilatory impairment. WPI classification
showed that about half of the patients have class 3 respiratory impairment. Conclusion
and Recommendations: Evaluation WPI using pulmonary functions should be done
for healthcare workers after recovery from COVID-19 infection and before they return
to work in order to determine their ability to practice their jobs.
