Abstract

Background/Aims
Performance of diagnostic or therapeutic endoscopic procedures in inflammatory bowel disease (IBD) patients can be challenging during a viral pandemic; the main concerns being the safety and protection of patients and health care providers (HCP). The aim of this study is to identify endoscopic practice patterns and outcomes of IBD and coronavirus disease 19 (COVID-19) with a worldwide survey of HCP.
Methods
The 20-item survey questionnaire was sent to physician members of the American Society for Gastrointestinal Endoscopy Special Interest Group in Interventional IBD, Chinese IBD Society Endoscopy Interest Group, and the China Crohn’s and Colitis Foundation.
Results
A total of 141 respondents submitted valid responses. Nighty-five respondents (67.9%) reported that at least 25% of their scheduled emergent endoscopic procedures were canceled or postponed during the pandemic. Fifty-six respondents (40.0%) have performed emergent endoscopy during the pandemic. A few respondents (9/140, 6.4%) estimated that more than 25% of their patients had worsened disease due to delayed or canceled emergent endoscopy procedures. More than 80% of respondents believed that personal protective equipment (PPE) for the endoscopy team, room sterilization, and pre-procedure screening of patients for COVID-19 were necessary. Out of 140 respondents, 16 (11.4%) reported that several of their patients had COVID-19. Eight clinicians (5.7%) reported that they or their endoscopy colleagues developed work-related COVID-19.
Conclusions
Cancellation of elective and emergent endoscopy in IBD care during the pandemic was common. Few respondents reported that their patients’ disease conditions worsened due to the cancellation of the endoscopy procedure. Most respondents voiced the need for proper PPE during the procedure regardless of patients’ COVID-19 status and screening the patients for COVID-19.

INTRODUCTION

The current coronavirus disease 19 (COVID-19) pandemic has resulted in illness in more than 3.7 million persons worldwide as of May 8, 2020. The infection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can lead to extra-pulmonary manifestations, including gastrointestinal (GI) symptoms. On the other hand, patients with underlying inflammatory bowel disease (IBD) may be susceptible to bacterial or viral infection either as a consequence of their underlying disease or immunosuppressive medications (ISM) as a treatment. In addition, patients with IBD often require endoscopic evaluation for the diagnosis, differential diagnosis, disease monitoring, assessment of treatment response, and therapeutic intervention. While most elective endoscopy has to be canceled or postponed for various reasons, emergent diagnostic or therapeutic endoscopy may be required during the pandemic. Interventional IBD, i.e. endoscopic management of complications of IBD or IBD surgery plays an important role in the provision of more effective treatment modalities than medical therapy and less invasive ways than surgical intervention. The main applications of interventional IBD include the following areas: (1) stricture therapy; (2) fistula and abscess therapy; (3) endoscopic management of colitis-associated neoplasia [1,2].

COVID-19 from the highly contagious pathogen has imposed tremendous stress and burden on patients, health care providers (HCP), health care facilities, and society. It has been particularly challenging for IBD patients with the underlying disease, the use of ISM, malnutrition, complications (such as strictures, bleeding, and abscess), or their requirement of periodic diagnostic or therapeutic endoscopy. Additionally, there have been concerns about the protection and safety of patients and the endoscopy team during the procedure. Between February 12 and April 9, 2020, 315,531 COVID-19 cases were reported to the Centers for Disease Control and Prevention (CDC) using a standardized form, 49,370 (16%) included data on whether the patient was an HCP in the United States. A total of 9,282 (19%) persons with COVID-19 were identified as HCP. As of May 7, 2020, a total of 1,219,066 cases were reported to CDC [3]. Endoscopists and endoscopy staff may be particularly vulnerable [4]. There is a lack of evidence-based guidelines regarding optimal endoscopy practice during a viral pandemic. Current guidelines from professional societies are largely based on expert opinions [4]. We urgently need real-world data. The current study was aimed to evaluate the practice pattern of IBD endoscopists in the management of their patients during the pandemic and to assess their concerns about personal protective equipment (PPE) and screening for COVID.

METHODS

1. Participants

Members of the American Society for Gastrointestinal Endoscopy (ASGE) Special Interest Group in Interventional IBD were surveyed with a structured 20-item anonymous questionnaire in both English and Chinese. In China, the questionnaires were distributed to physician members of the Chinese IBD Society Special Interest Group in IBD and the China Crohn’s and Colitis Foundation. Of note, clinicians in Wuhan, the epicenter of COVID-19 in China were also enrolled. The survey was administered between April 12 and April 19, 2020.

The inclusion criteria for qualified HCP were: (1) general gastroenterologists with a practice including IBD; (2) IBD specialists doing diagnostic or therapeutic endoscopy for IBD patients; (3) colorectal surgeons specialized in IBD surgery doing diagnostic and/or therapeutic endoscopy for IBD patients; and (4) advanced therapeutic endoscopist also treating IBD complications such as endoscopic balloon dilation of strictures.

The central institutional review board for the study was approved by the ethics committee of the 2nd Hospital of Zhejiang University (approval No. 2020001357).

2. Survey Questionnaire

The questionnaire was drafted and revised by core members of the research team (Y.C., C.N.B., F.A.F., R.P.K., and B.S.) based on a comprehensive review of the literature and personal expertise. The questionnaires mainly consisted of non-open-ended questions from the following categories: (1) HCP’s practice setting and criteria of emergent versus elective endoscopy in IBD; (2) endoscopy practice patterns; and (3) risk and protective measures in the endoscopy suite and endoscopy team. The estimated time to complete the survey was from 5 to 7 minutes. The validity of answered questionnaires was performed by blinded investigators (Y.C., Q.Y., and B.S.). Data were sorted based on the category.

3. Statistical Analysis

Categorical variables were expressed as frequencies and percentages. Descriptive statistics were performed.

RESULTS

A total of 142 answered questionnaires were received with 141 deemed valid responses, 16 respondents from the United States and 125 from China.

1. Practice Setting and Volume and Criteria for Emergent and Elective Endoscopy in IBD

More than 50% were IBD clinicians or IBD endoscopists. Seventeen respondents (12.1%) are the members of the ASGE Special Interest Group or the Global Interventional IBD Group. Of note, 7 respondents were from the City of Wuhan, the epicenter of the COVID-19 pandemic in China, of whom 6 were gastroenterologists with > 30% of IBD practice and 1 gastroenterologist with < 30% of IBD practice.

The weekly patient volume of IBD was significantly higher for the Chinese clinicians than the U.S. clinicians during the pandemic.

Fifty percent or more respondents felt that emergent endoscopy was applied to newly-onset acute severe colitis suspected of ulcerative colitis (UC) and Crohn’s disease (CD) with clinically significant anastomosis bleeding, UC with endoscopically resectable polypoid lesion with high-grade dysplasia, and acute cholangitis in the setting or primary sclerosing cholangitis (Table 1).

2. Practice Patterns during COVID-19

Nighty-five respondents (67.9%) reported that at least 25% of their scheduled emergent endoscopic procedures were canceled or postponed. All 7 respondents from the City of Wuhan reported that at least 25% of their patients’ endoscopy was canceled or postponed for the concern about the risk of COVID-19. The main reasons for the cancellation or postponing of the scheduled IBD endoscopy are (1) patient decision; (2) endoscopist’s concerns about the safety of patients and treatment team; and (3) local governmental or institutional restriction (Table 1).

Fifty-six respondents (40.0%) performed emergent endoscopy during the pandemic. There were some agreements and disagreement on the criteria of emergent endoscopy in IBD patients, with posted scenarios. More than 50% of respondents believed that emergent endoscopy was applied to new-onset acute severe colitis, CD with anastomotic ulcer bleeding, concurrent UC and primary sclerosing cholangitis with acute cholangitis. In contrast, less than 50% of respondents believed that symptomatic CD-associated strictures in outpatients or inpatients required emergent endoscopy. In reality, more than 50% of responders have performed emergent endoscopy for precolectomy diagnosis for acute severe colitis. Precolectomy diagnosis of severe acute colitis for the diagnosis IBD in some settings may be not be considered as a true indication for emergent endoscopy.

A few respondents (9/140, 6.4%) estimated that more than 25% of their patients had a worsened disease due to delayed or canceled emergent endoscopy procedure (Table 1).

Out of 140 respondents, 16 (11.4%) reported that some of their patients had COVID-19, including 8 (5.7%) on CD patients, 4 (2.9%) on UC patients, and 4 (2.9%) on ileal pouch patients (Table 2). None of 7 respondents from the City of Wuhan reported that any of their IBD patients had COVID-19. Interestingly, only 1 Chinese respondent reported seeing IBD patients with COVID-19, and 15 U.S. clinicians reported some of their CD, UC, or ileal pouch patients had COVID-19 (P<0.01).

3. Risk and Protective Measures in the Endoscopy Suite and Endoscopy Team for COVID-19

More than 80% of respondents, including all 7 respondents from the City of Wuhan believed that proper PPE for the endoscopy team, room sterilization, pre-procedure screening of patients for COVID-19 were necessary. Eighty-two respondents (58.6%) recommended allowing the patient to wear PPE as well. For patients with or suspected of COVID-19, almost all respondents (138/140, 98.6%) believed that HCP should wear proper PPE, consisting of filtering facepiece 2 (FFP2), FFP3, or N95 face masks, goggles or face shield, long-sleeved water-resistant gowns, and gloves. For patients without COVID-19, a vast majority of respondents (> 80%) recommended that HCP wore all PPE. Eight clinicians (5.7%) reported that they or their endoscopy colleagues developed work-related COVID-19 (Table 3). Of the 8 clinicians, 2 (1.6%) from China and 6 (37.6%) from the United States reported that they or their colleagues contracted COVID-19 (P<0.01).

DISCUSSION

The arrival of COVID-19 pandemic has changed the world in every aspect. Persons with IBD are susceptible to these changes regarding office visits, the use of ISM, endoscopy, hospitalization, and surgery. Endoscopy plays a key role in diagnosis, disease monitoring, and treatment. Alterations in IBD care during the pandemic include the scheduling, utilization, and execution of endoscopy. Two-thirds of respondents reported that at least 25% of their scheduled emergent endoscopic procedures were canceled or postponed. The main reasons for the cancellation or delay in endoscopy were patients’ personal decisions and the endoscopists’ concerns about the safety of patients and the treatment team. Among listed scenarios, such as new-onset acute severe colitis suspicious for IBD, CD patients with anastomotic ulcer bleeding, or acute cholangitis from primary sclerosing cholangitis. In addition, the majority of respondents voiced the mandate of suspending non-emergent endoscopy. The survey listed several common scenarios of emergent endoscopy with a good agreement among responders. The data showed that there was an overwhelming concern about PPE during endoscopy procedures.

Complications, such as stricture, fistula, abscess, and bleeding, are common in IBD patients, particularly in those with prior surgery. Most of these complications require periodic endoscopic therapy, such as balloon dilation and endoscopic stricturotomy. The endoscopic management of symptomatic patients during the pandemic has been challenging. Professional societies’ guidelines have recommended assuring the highest level of endoscopy care as well as protection against COVID-19 for both patients and endoscopy suite personnel [3,5]. The question is how can these measures be implemented. Elective endoscopy has been postponed based on governmental or institutional mandates, patients’ preferences, or endoscopist discretion, as shown in the current study. There are no setup criteria for emergent endoscopy. Results of our survey revealed some agreement and disagreement on the criteria of emergent endoscopy in IBD care. Practically the decision to perform the urgently needed endoscopy was at the discretion of treating endoscopists.

With regards to the performance of emergent endoscopy, the risk of delayed therapy with the subsequent possibility of worsening disease course versus the risk of COVID for both patients and HCPs in the endoscopy setting should be carefully balanced. Even some emergent endoscopic procedures have to be canceled. Fortunately, the majority of respondents (93.6%) reported that less than 25% of patients with canceled emergent endoscopy experienced worsened disease. On the other hand, HCPs carry a higher risk for COVID-19 [3]. GI endoscopists and endoscopy personnel is at a particularly higher risk for acquisition of COVID-19 [4,6]. Sixteen respondents (11.4%) reported that some of their patients had COVID-19, including 8 (5.7%) on CD patients, 4 (2.9%) on UC patients, and 4 (2.9%) on ileal pouch patients. Eight respondents (5.71%) reported that they or their endoscopy colleagues developed work-related COVID-19. If elective or some emergent IBD endoscopy can be cautiously postponed, it will reduce the risk of exposure of patients as well as HCPs to COVID-19.

Patients with COVID-19 can present with GI symptoms, such as bloating, nausea, abdominal pain, and diarrhea. Some of the patients may not have concurrent respiratory symptoms [7]. These symptoms are not specific, which may mimic a flare of underlying IBD. The role of endoscopic evaluation for the distinction between COVID-19 with GI presentations and IBD disease flare is not clear. There are no published data on colonoscopic and histologic features in patients COVID-19 or SARS-CoV-2. Therefore, it is recommended that IBD patients with GI symptoms suspected of having SARS-CoV-2 or COVID-19 should initially have non-endoscopic evaluation [8]. In this survey, 50% of the respondents performed emergent endoscopy for the precolectomy diagnosis of acute severe colitis suspected of IBD.

COVID-19 is primarily spread through droplet transmission. However, endoscopic procedures, for example, upper endoscopy, may cause aerosolization, and subsequent airborne transmission. Adequate personal protection and room setting are critical for the prevention of work-related COVID-19 [9,10].

There has been debate as to what the proper PPE should be for endoscopy personnel [5]. The American Gastroenterological Association guidelines recommended the use of N95-type face masks for all HCPs performing upper GI or lower GI endoscopic procedures, regardless of patients’ COVID-19 status [6]. Recommended PPEs for GI endoscopy from various professional societies have been published [11]. The results of this survey study showed that the overwhelming number of respondents recommended high-quality face masks (such as N95), goggles or face shield, long-sleeved water-resistant gowns, and gloves when performing endoscopy procedure in patients regardless COVID-19 status. Eighty-two responders (58.6%) recommended letting the patient wear PPE as well, which could be applicable in IBD patients undergoing lower GI endoscopy. In addition, most respondents recommended room sterilization and pre-procedure screening of patients for COVID-19.

The findings of this study have several clinical implications. The cancellation of diagnostic or therapeutic endoscopy procedures for IBD is common for multiple reasons, including patients and endoscopists’ concerns about the safety, personal protection, logistics (such as transportation and lodging during shelter-in-place), and the government’s or institutional mandates. Most States’ governments required cancellation or postponing of elective surgery or procedures. However, the definition of emergent endoscopy in IBD varies. The criteria of emergent IBD endoscopy has not been listed in professional societies’ recommendations [11]. Several scenarios of emergent endoscopy for IBD are listed in our recent consensus statement [12]. Not all emergent endoscopies in IBD are therapeutic. For example, in this study, precolectomy endoscopy for the evaluation of acute severe colitis may be considered as an emergent procedure by some responders. Although the cancellation is common, it appears that disease progression due to the cancellation is uncommon. The group of respondents voiced concerns about PPE. In addition, the highly accurate point-of-care screening of patients for COVID-19 should become feasible in the United States, Canada, and Europe.

There are limitations to our study. This is not a controlled study. There might have been selection or recall bias. The respondents from the United States and China, with the majority being from the latter. The sample size may not be large enough to detect subtle changes and differences. The survey method using social media in WeChat in China would preclude the knowledge of the total number of clinicians who viewed the survey and who did not respond. The respondents represent a spectrum of IBD practice, from medical, endoscopic, to surgical, and from adult to pediatric service. The respondents from the epicenters of COVID-19 or from high-volume IBD centers may have a different experience than the others. Since the survey was obtained from clinicians, detailed clinical data of each patient were not available. With evolving pandemic of COVID-19 our knowledge of the virus and the management of COVID and underlying diseases are improving. The practice pattern of IBD care can be dynamic.

In conclusion, the cancellation of elective or emergent endoscopy in IBD care during the pandemic was common. There are agreement and disagreement in the criteria of emergent IBD endoscopy. Few respondents reported that their patients’ disease conditions worsened due to the cancellation of the scheduled endoscopy procedure. Most respondents voiced the need for proper PPE during the procedure regardless of patients’ COVID-19 status and recommended screening of the patient for the viral infection. The risks and benefits of performing diagnostic or therapeutic IBD endoscopy during the pandemic should be carefully balanced.
