Abstract
Over the past few decades, there has been an exponential increase in the utilization of endoscopic procedures. Accurately predicting the demand is crucial for effective capacity planning and resource allocation in the endoscopic unit. However, predictive models are not integrated into current endoscopy software. To overcome this limitation, our group used data on the demand in our tertiary unit from 2015 to 2021 (83 months) to develop forecast models using exponential smoothing techniques adjusted for trend and seasonality (derivation phase). These models were recently published at the Revista Española de Enfermedades Digestivas.

Abstract
INTRODUCTION The coronavirus disease 19 (COVID-19) pandemic disrupted endoscopy practices, creating unprecedented decreases in cancer screening and surveillance services. We aimed to assess the impact of the pandemic on the proportion of patients diagnosed with Barrett's esophagus (BE) and BE-related dysplasia and adherence to established quality indicators. METHODS Data from all esophagogastroduodenoscopies in the GI Quality Improvement Consortium, a national repository of matched endoscopy and pathology data, were analyzed from January 2018 to December 2022. Four cohorts were created based on procedure date and COVID-19 data: pre-pandemic (January 2018 to February 2020), pandemic-phase I (March 2020 to July 2020), pandemic-phase II (August 2020 to May 2021), and pandemic-phase III (June 2021 to December 2022). Observed and expected number of BE and BE-related dysplasia cases per month and adherence to the Seattle biopsy protocol and recommended surveillance intervals for nondysplastic BE (NDBE) were evaluated. RESULTS Among 2,446,857 esophagogastroduodenoscopies performed during the study period, 104,124 (4.3%) had pathology-confirmed BE. The histologic distribution was 87.4% NDBE, 1.8% low-grade dysplasia, 2.4% indefinite for dysplasia, and 1.4% high-grade dysplasia. The number of monthly BE (-47.9% pandemic-phase I, -21.5% pandemic-phase II, and -19.0% pandemic-phase III) and BE-related dysplasia (high-grade dysplasia: 41.2%, -27.7%, and -19.0%; low-grade dysplasia: 49.1%, -35.3%, and -26.5%; any dysplasia: 46.7%, -32.3%, and -27.9%) diagnoses were significantly reduced during the pandemic phases compared with pre-pandemic data. Adherence rates to the Seattle protocol and recommended surveillance intervals for NDBE did not decline during the pandemic. DISCUSSION There was a significant decline in the number of BE and BE-related dysplasia diagnoses during the COVID-19 pandemic, with an approximately 50% reduction in the number of cases of dysplasia diagnosed in the early pandemic. The absence of a compensatory increase in diagnoses in the pandemic-phase II and III periods may result in deleterious downstream effects on esophageal adenocarcinoma morbidity and mortality.

The impact of COVID-19 on national program of colorectal cancer screening in Tehran, Iran: a multicenter study. BMC Cancer 2023; 23:627. [PMID: 37407931 DOI: 10.1186/s12885-023-11111-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Accepted: 06/26/2023] [Indexed: 07/07/2023] Open
Abstract
BACKGROUND The COVID-19 pandemic has affected all aspects of the healthcare system, including prevention, treatment, rehabilitation of diseases and health education; access to essential therapies; allocation of finance & facilities to health issues, and governance of diseases, including COVID-19 and other diseases. Consequently, the burden of COVID-19 was not only attributable to the multiorgan involvement and detailed presentation of the disease but also to the inadequate management of other diseases resulting from the exclusive allocation of resources and medical personnel to the pandemic crisis. Over the mentioned period, one observed deficiency was the lack of public and official favor for conventional screening protocols. To this end, this study aims to evaluate the impact of the COVID-19 pandemic on colorectal cancer (CRC) screening protocols at Shahid Beheshti University of Medical Sciences in Tehran, Iran, in an effort to identify individuals at risk for CRC and provide them with intensive screening and therapy. METHODS This is an observational study comparing the number of candidates for CRC screening referred to primary, secondary, and tertiary health-care centers under supervision of Shahid Beheshti University of Medical Sciences (SBMU), Tehran, Iran in a 2-year interval before and after COVID-19 pandemics. Patients with intermediate- and high-risk criteria for colorectal cancer were included in the study and were screened by fecal immunochemical test. Patients with positive or indeterminate fecal test results were further evaluated with colonoscopy in research institute for gastroenterology and liver diseases where is a tertiary referral center for CRC screening. Finally, the decrease percentage of screening tests and endoscopic findings during the pandemic period compared to pre-pandemic period was calculated and interpreted. RESULTS A significant decrease in the number of performed fecal immunochemical tests (FITs), referred positive FITs, and referred patients with positive alarm signs to the Research Institute of Gastroenterology and Liver Diseases (RIGLD) center inevitably led to a considerable decrease in the number of endoscopic findings, including high-risk adenomas, sessile serrated polyps, and even early-stage colorectal cancers (CRCs). CONCLUSION The disruption of screening protocols caused by the COVID-19 pandemic appears to increase the number of patients with high-grade and end-stage CRCs referred in the near future.

Abstract
BACKGROUND Coronavirus disease 2019, known as a widespread, aerosol spreading disease, has affected >549 000 000 people since 2019. During the lockdown period, dramatic reduction of elective endoscopic procedures, including endoscopic retrograde cholangiopancreatography, had been reported worldwide, leading to delayed diagnosis and treatment. Nevertheless, whether patients' hospital stays and complication rate of endoscopic retrograde cholangiopancreatography (ERCP) during the lockdown period were influenced by the pandemic still remains controversial. METHODS Patients who diagnosed with obstructive jaundice and acute cholangitis in the lockdown period, May 16 to July 26, 2021, were compared to the same prepandemic period in 2019. RESULTS A total of 204 patients in 2019 and 168 patients in 2021 were diagnosed with acute biliary cholangitis or obstructive jaundice, and 82 of the patients in 2019 and 77 patients in 2021 underwent ERCP ( p = 0.274). Patients whose quick Sequential Organ Failure Assessment (qSOFA) score was ≥ 2 occurred more during the lockdown period than during the normal period (24/77, 31.1% vs 12/82, 14.6%; p = 0.013). The initial laboratory data, including, total bilirubin (4.12 in 2021 vs 3.08 mg/dL in 2019; p = 0.014), gamma-glutamyl transferase (378 in 2021 vs 261 U/L in 2019; p = 0.009), and alkaline phosphatase (254 in 2021 vs 174 U/L in 2019; p = 0.002) were higher during the lockdown period compared to 2019. Hospital stay was statistically significant longer in the lockdown period (11 days [7.00-22.00] in 2021 vs 8 days in 2019 [6.00-12.00]; p value = 0.02). Multivariate analysis showed that qSOFA ≥ 2 (hazard ratio [HR] = 3.837, 95% confidence interval [CI] = 1.471-10.003; p = 0.006), and malignant etiology (HR = 2.932, 95% CI = 1.271-6.765; p = 0.012) were the statistically significant factors for a prolonged hospital stay, which was defined as hospital stay >21 days. ERCP-related complications and mortality rate were not statistically different between the two periods. CONCLUSION Patients from May 16 to July 26, 2021, the lockdown period, had longer hospital stays and higher biliary tract enzyme levels, which indicated more severe disease. Nevertheless, ERCP could be safely and successfully performed even during the medical level 3 alert lockdown period without causing an increase in procedure-related complications and mortality.

Abstract
BACKGROUND The impact of the coronavirus on hospitalizations for gastrointestinal (GI) disease, particularly at a population level is understudied.
AIM To investigate trends in hospitalizations, inpatient endoscopy resource utilization, and outcomes during the first year of the coronavirus pandemic and subsequent lockdowns.
METHODS Using the California State Inpatient Database for 2018-2020, we explored year-to-year and 2020 month-to-month trends in hospitalizations, length of stay, and inpatient mortality (all-cause & viral pneumonia-specific) for common inpatient GI diagnoses including acute pancreatitis, diverticulitis, cholelithiasis, non-infectious gastroenteritis, upper and lower GI bleeding (LGIB), Clostridium difficile, viral gastroenteritis, inflammatory bowel disease, and acute cholangitis.
RESULTS Disease-specific hospitalizations decreased for all included conditions except nonvariceal upper GI bleeding (NVUGIB), LGIB, and ulcerative colitis (UC) (ptrend < 0.0001). All-cause inpatient mortality was higher in 2020 vs 2019, for acute pancreatitis (P = 0.029), diverticulitis (P = 0.04), NVUGIB (P = 0.003), and Crohn’s disease (P = 0.004). In 2020, hospitalization rates were lowest in April, November, and December. There was no significant corresponding increase in inpatient mortality except in UC (ptrend = 0.048). Viral pneumonia and viral pneumonia complicated by respiratory failure increased (P < 0.001) among GI hospitalizations. Endoscopy utilization within 24 h of admission was unchanged for GI emergencies except NVUGIB (P < 0.001).
CONCLUSION Our findings suggest that hospitalization rates for common GI conditions significantly declined in California during the COVID pandemic, particularly in April, November and December 2020. All-cause mortality was significantly higher among acute pancreatitis, diverticulitis, NVUGIB, and Crohn’s disease hospitalizations. Emergency endoscopy rates were mostly comparable between 2020 and 2019.

Abstract
The impact of the coronavirus disease 2019 (COVID-19) pandemic has been immense, and it continues to have lasting repercussions. While the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus primarily infects the respiratory system, other organ systems are affected, including the liver. Scientific knowledge on the role of SARS-CoV-2 infection and liver injury has evolved rapidly, with recent data suggesting specific hepatotropism of SARS-CoV-2. Moreover, additional concerns have been raised in regard to long-term liver damage, related to emerging cases of post-COVID-19 cholangiopathy and chronic cholestasis. Great effort has also been focused on studying how specific subpopulations with chronic medical conditions might be disproportionately impacted by COVID-19. One such population includes individuals with chronic liver disease (CLD) and cirrhosis, with an expanding body of research indicating these patients being particularly susceptible to adverse outcomes. In this review, we provide an updated summary on the current pathogenesis and mechanism of liver injury in the setting of SARS-CoV-2 infection, the association between health outcomes and SARS-CoV-2 infection in patients with CLD, and the unique consequences of the COVID-19 pandemic on the routine care of patients with CLD.

Abstract
BACKGROUND Many colorectal cancer-related procedures were suspended during the COVID-19 pandemic. In this study, we predict the impact of resulting delays in screening (colonoscopy, FIT, and sigmoidoscopy) and diagnosis on colorectal cancer-related outcomes, and compare different recovery scenarios. METHODS Using the MISCAN-Colon model, we simulated the US population and evaluated different impact and recovery scenarios. Scenarios were defined by the duration and severity of the disruption (percentage of eligible adults affected), the length of delays, and the duration of the recovery. During recovery (6, 12 or 24 months), capacity was increased to catch up missed procedures. Primary outcomes were excess colorectal cancer cases and -related deaths, and additional colonoscopies required during recovery. RESULTS With a 24-month recovery, the model predicted that the US population would develop 7,210 (0.18%) excess colorectal cancer cases during 2020-2040, and 6,950 (0.65%) excess colorectal cancer-related deaths, and require 108,500 (8.6%) additional colonoscopies per recovery month, compared with a no-disruption scenario. Shorter recovery periods of 6 and 12 months, respectively, decreased excess colorectal cancer-related deaths to 4,190 (0.39%) and 4,580 (0.43%), at the expense of 260,200-590,100 (20.7%-47.0%) additional colonoscopies per month. CONCLUSIONS The COVID-19 pandemic will likely cause more than 4,000 excess colorectal cancer-related deaths in the US, which could increase to more than 7,000 if recovery periods are longer. IMPACT Our results highlight that catching-up colorectal cancer-related services within 12 months provides a good balance between required resources and mitigation of the impact of the disruption on colorectal cancer-related deaths.

Abstract
The SARS-CoV2 pandemic has had a profound and lasting impact on healthcare delivery. Gastrointestinal endoscopy services were limited during the early phases of the pandemic, which has resulted in ongoing procedural backlog. Procedural delays have had continuing effects including delayed colorectal cancer (CRC) diagnoses and exacerbation of existing disparities in the CRC-screening and treatment pathways. In this review, we outline these effects as well as the variety of strategies that have been proposed to eliminate this backlog, including increased endoscopy hours, re-triaging of referrals, and alternative CRC-screening strategies.

Abstract
Robotic colonoscopes could potentially provide a comfortable, less painful and safer alternative to standard colonoscopy. Recent exciting developments in this field are pushing the boundaries to what is possible in the future. This article provides a comprehensive review of the current work in robotic colonoscopes including self-propelled, steerable and disposable endoscopes that could be alternatives to standard colonoscopy. We discuss the advantages and disadvantages of these systems currently in development and highlight the technical readiness of each system to help the reader understand where and when such systems may be available for routine clinical use and get an idea of where and in which situation they can best be deployed.

Abstract
BACKGROUND & AIMS The COVID-19 pandemic has affected clinical services globally, including colorectal cancer (CRC) screening and diagnostic testing. We investigated the pandemic's impact on fecal immunochemical test (FIT) screening, colonoscopy utilization, and colorectal neoplasia detection across 21 medical centers in a large integrated health care organization. METHODS We performed a retrospective cohort study in Kaiser Permanente Northern California patients ages 18 to 89 years in 2019 and 2020 and measured changes in the numbers of mailed, completed, and positive FITs; colonoscopies; and cases of colorectal neoplasia detected by colonoscopy in 2020 vs 2019. RESULTS FIT kit mailings ceased in mid-March through April 2020 but then rebounded and there was an 8.7% increase in kits mailed compared with 2019. With the later mailing of FIT kits, there were 9.0% fewer FITs completed and 10.1% fewer positive tests in 2020 vs 2019. Colonoscopy volumes declined 79.4% in April 2020 compared with April 2019 but recovered to near pre-pandemic volumes in September through December, resulting in a 26.9% decline in total colonoscopies performed in 2020. The number of patients diagnosed by colonoscopy with CRC and advanced adenoma declined by 8.7% and 26.9%, respectively, in 2020 vs 2019. CONCLUSIONS The pandemic led to fewer FIT screenings and colonoscopies in 2020 vs 2019; however, after the lifting of shelter-in-place orders, FIT screenings exceeded, and colonoscopy volumes nearly reached numbers from those same months in 2019. Overall, there was an 8.7% reduction in CRC cases diagnosed by colonoscopy in 2020. These data may help inform the development of strategies for CRC screening and diagnostic testing during future national emergencies.

Nasir A, Hough B, Baffa C, Khazanchi A, Coppola D. An Analysis of the Impact of COVID-19 Pandemic-related Lockdown Measures on a Large Gastrointestinal Pathology Service in the United States. CANCER DIAGNOSIS & PROGNOSIS 2022; 2:422-428. [PMID: 35813009 PMCID: PMC9254096 DOI: 10.21873/cdp.10125] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Accepted: 06/07/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND/AIM The coronavirus disease 2019 (COVID-19) pandemic prompted global recommendations to delay non-urgent endoscopic procedures to limit the spread of SARS-COV-2, but such delays had unprecedented impact on the delivery of healthcare. Being a large specialty GI Pathology service, we sought to analyze the effect of the pandemic on the frequency of GI malignancies in our department. PATIENTS AND METHODS Based on the electronic search of departmental pathology records, we compared the total numbers of cancer diagnoses (primary and metastatic) from various GI biopsy sites during the 12-month pre- and post-pandemic periods. We summarized patient demographics and analyzed pertinent histopathologic data. RESULTS For all GI biopsy sites, the number of intramucosal/invasive malignancies reported during the one-year pre-COVID-19 pandemic (pre-COVID) and post-COVID-19 pandemic national lockdown (post-COVID) observation periods were 146 and 218, respectively. Among these, 32 and 70 malignancies were reported for the first quarter (representing the earliest post-lockdown period), 29 and 53 for the second, 41 and 54 for the third, and 44 and 41 for the fourth quarter. During the first two quarters of the post-COVID observation period, the increase in malignant diagnoses was most profound, showing 119% post-COVID increase compared to the pre-COVID levels. Of the two main primary histologic types of large intestinal carcinomas [adenocarcinoma (ADC) and squamous cell carcinoma (SCC)], the most profound post-COVID increase was noted in SCCs (136% vs. 58% for ADCs). CONCLUSION Compared to the pre-pandemic baseline, the COVID-19 pandemic caused a major increase in biopsy diagnoses of GI cancers in our department. The most plausible explanations for this trend include inevitable lockdowns to minimize the spread of SAR-COV2, which affected GI endoscopy procedure schedules/re-schedules as well as patient response and adaptation to emerging post-COVID GI healthcare patterns. The COVID-19 pandemic's long-term impact on the health of GI cancer patients will need to be determined through systematic analyses by multi-disciplinary teams.
