Triage of General Gastrointestinal Endoscopic Procedures During the COVID-19 Pandemic: Results From a National Delphi Consensus Panel

GIE Editorial Board top 10 topics: advances in GI endoscopy in 2020

The American Society for Gastrointestinal Endoscopy's Gastrointestinal Endoscopy Editorial Board reviewed a systematic literature search of original endoscopy-related articles published during 2020 in Gastrointestinal Endoscopy and 10 other high-impact medical and gastroenterology journals. Votes from each individual board member were tallied to identify a consensus list of the 10 most significant topic areas in GI endoscopy over the calendar year of study using 4 criteria: significance, novelty, impact on national health, and impact on global health. The 10 areas identified were as follows: artificial intelligence in endoscopy, coronavirus disease 2019 and GI practice, third-space endoscopy, lumen-apposing metal stents, single-use duodenoscopes and other disposable equipment, endosonographic needle technology and techniques, endoscopic closure devices, advances in GI bleeding management, improvements in polypectomy techniques, and bariatric endoscopy. Each board member contributed a summary of important articles relevant to 1 to 2 topic areas, leading to a collective summary that is presented in this document of the "top 10" endoscopic advances of 2020.

Impact of the COVID-19 pandemic on utilization of EGD and colonoscopy in the US: An Analysis of the GIQuIC Registry

Background and aims

The coronavirus disease 2019 (COVID-19) pandemic has limited the ability to perform endoscopy. The aim of this study was to quantify the impact of the pandemic on endoscopy volumes and indications in the US.

Methods

We performed a retrospective analysis of data from the GI Quality Improvement Consortium (GIQuIC) registry. We compared volumes of colonoscopy and esophagogastroduodenoscopy (EGD) during the pandemic (March to September 2020) to before the pandemic (January 2019 through February 2020). The primary outcome was change in monthly volumes. Secondary outcomes included changes in the distribution of procedure indications and in procedure volume by region of US, patient characteristics, trainee involvement, and practice setting, as well as colorectal cancer diagnoses.

Results

Among 451 sites with 3,514 endoscopists, the average monthly volume of colonoscopies and EGDs dropped by 38.5% and 33.4%, respectively. There was regional variation, with the greatest and least decline in procedures in the Northeast and South, respectively. There was a modest shift in procedure indications from prevention to diagnostic, an initial increase in performance in the hospital setting, and a decrease in procedures with trainees. The decline in volume of colonoscopy and EGD during the first seven months of the pandemic was equivalent to approximately 2.7 and 2.4 months of pre-pandemic productivity, respectively. Thirty percent fewer colorectal cancers were diagnosed compared to expected.

Conclusions

These data on actual endoscopy utilization nationally during the pandemic can help in anticipating impact of delays in care on outcomes and planning for the recovery phase.

Patient Perspective on Safety of Elective Gastrointestinal Endoscopy During the COVID-19 Pandemic

Background

Patients' perception regarding the risks of COVID-19 infection with gastrointestinal (GI) and the preventive measures taken in GI endoscopy units to mitigate infection risk remains unclear. We aimed to assess patients' perception regarding risks of COVID-19 with GI endoscopy and the changes in the endoscopy unit as a result of the ongoing pandemic.

Methods

Outpatients undergoing GI endoscopy at our institution were categorized into those scheduled to undergo GI endoscopy (preprocedure) and those who had recently undergone GI endoscopy during the pandemic (postprocedure). Two separate but similar survey instruments were designed. Patients were asked to respond on a 5-point Likert scale. Responses were stratified as "low," "neutral," and "high" for analysis.

Results

A total of 150 and 355 respondents completed the preprocedure and postprocedure surveys, with a combined response rate of 82.5%. Non-white ethnicity was associated with reporting a "high" level of concern for endoscopy related COVID-19 exposure in both the preprocedure (OR 4.09, 95% CI 1.54-10.82) and postprocedure cohorts (OR 2.11, 95% CI 1.04-4.29). 42% of patients in the preprocedure cohort and 11.8% in the postprocedure cohort reported their level of concern for COVID exposure as "high." Among the postprocedure cohort, 88% of the patients were likely to undergo repeat endoscopy during the pandemic if recommended.

Conclusion

Patients are willing to undergo GI endoscopy during the COVID-19 pandemic. Non-white and older patients, and those undergoing screening examinations were more concerned with the GI endoscopy related COVID-19 transmission risk.
