Persistent/Late Complications of COVID-19 in Affected Emergency Medical Technicians: A Case Series and Brief Literature Review

ABSTRACT

Background: The present study aimed to assess the prevalence of persistent/late complications after recovery from the acute phase of COVID-19 in emergency medical technicians (EMTs). Methods: This is a cross-sectional case-series study performed during the last quarter of 2020 in Tehran, Iran. All EMTs who had been diagnosed with COVID-19 were eligible. The researcher contacted the EMTs via telephone to determine any complications following their recovery. Those who suffered from any complication were referred to an internal specialist physician for a detailed history and physical examination. Based on the physician’s opinion, some paraclinical or clinical evaluations were requested to be performed. Results: Four hundred thirty-one confirmed cases and two deaths due to this disease were registered among the Tehran EMS center’s EMTs during the study period. Two hundred thirty-eight EMTs were contacted, and 22.7% of them had at least one persistent/late complication following recovery of the acute phase of COVID-19;of whom, 28 EMTs were visited by an internist and completed the tests. The final participants mentioned seventy-five persistent/late complications. Only one EMT had a residual lesion among those who underwent lung CT scans. There were also some pathological findings in the echocardiographic examination and spirometry. Conclusion: Our study showed that persistent/late-onset complications could likely accompany by COVID-19. © 2022 Bentham Science Publishers.
