COVID-19 screening before gastrointestinal procedures

Abstract

Abstract Background In March 2020, the World Health Organization declared coronavirus 2019 (COVID-19) a global pandemic. We aimed to assess the ability of COVID-19 screening to detect preprocedural infection at the gastrointestinal units. One hundred and three patients indicated for gastrointestinal tract interventional procedures were included. All patients surveyed for COVID-19-related symptoms and COVID-19 rapid IgM/IgG antibodies. Symptomatic and COVID-19 antibody-positive patients further tested for COVID-19 reverse transcriptase by polymerase chain reaction (RT-PCR). All patients contacted, 14 days after the procedure and asked about the possible development of COVID-19. All health care workers (HCWs) (n=18) were screened weekly for COVID-19-related symptoms. Results The mean age was 46.11 ± 17.16 years of them 58.25% were males. 2.9% patients had COVID-19-related symptoms and 97.1% were asymptomatic. All symptomatic patients tested positive for COVID-19 IgM antibody and RT-PCR. Among asymptomatic patients 23% had positive COVID-19 antibodies, of them 56.5%patients had positive RT-PCR. One HCW developed COVID-19 during the study. None of the included patients developed new onset of COVID-19 infection, two weeks after the procedure. Conclusion COVID-19 antibody test may be a reasonable preprocedural screening method for low-income countries and COVID-19 RT-PCR screening for symptomatic patients and those with positive COVID-19 antibody test.
