Appropriateness of high-priority criteria and safety of endoscopy procedures during the COVID-19 lockdown
During the coronavirus-19 disease (COVID-19) pandemic, gastroenterology guidelines recommended the suspension or reduction of non-urgent endoscopy. We aimed to assess the appropriateness and safety of endoscopic activity during the pandemic first wave lockdown using European Society of Gastrointestinal Endoscopy (ESGE) recommendations.We identified scheduled patients from the onset of the lockdown in Spain since March 16, 2020) to April 14, 2020. Daily hospital COVID-19-related burden was also registered. A similar cohort from a period immediately before the lockdown was studied (pre-lockdown cohort) to compare appropriateness.454 endoscopy procedures were performed during the studied period, comprising a 49.7% reduction compared to the pre-lockdown cohort (n = 913). There was a significant increase in ESGE high-priority indications (62.1% vs. 45.6%, p<0.001) associated with an increase in relevant endoscopic findings (p = 0.006), advanced neoplasia/cancer (p = 0.004) and cancer detection rate (p = 0.010). There were no differences in the rate of admissions or infection among scheduled patients in the lockdown cohort. None of the staff members tested positive for COVID-19 in the 7 days after the adoption of protective measures.A prioritized endoscopic activity is not associated with higher contagion after adopting protective measures. In addition, a triage of procedures that follow the ESGE criteria increases the rate of relevant endoscopic findings. These considerations may reduce the impact of the delays of diagnosis after the pandemic.
