Local health systems aim to contain the COVID‐19 pandemic and hospitals and health care providers rush to provide the capacity for a surge of COVID‐19 patients. However, the short, medium‐ and long‐term outcomes of patients with gastrointestinal (GI) diseases without COVID‐19 will be affected by the ability to develop locally adapted strategies to meet their service needs in the COVID‐19 setting. To mitigate risks for patients with GI diseases, it is useful to differentiate three phases: 1) the acute phase, 2) the adaptation phase and 3) the consolidation phase. During the acute phase, service delivery for patients with GI disease will be curtailed to meet competing health care needs of COVID‐19 patients. During the adaptation phase, GI‐services are calibrated towards a ‘new normal’ and the consolidation phase is characterised by rapid introduction and ongoing refinement of services. Proactive planning with engagement of relevant stakeholders including consumer representatives is required to be prepared for a variety of scenarios that are dictated by thus far undefined long‐term economic and societal impacts of the pandemic. Since substantial changes ‐to the delivery of services are likely to occur, it is important that these changes are embedded into quality and research frameworks to ensure that data are generated that support evidence‐based decision‐making during the adaptation and consolidation phases. The Corona Virus Disease-19 pandemic presents an unprecedented challenge to health systems around the world. From a health systems perspective a spectrum of measures that include strict isolation, avoidance of social contacts, testing coupled with contact tracing and (re-) allocation of resources, both manpower and equipment, to manage large numbers of acutely ill patients requiring inpatient or even intensive care are key to controlling this viral pandemic 1, 2 . These measures are required until effective antiviral therapies and/or vaccination are available. Despite the expectations of some that COVID-19 will be rapidly controlled, it is likely that these measures will be in place not just temporarily but for a prolonged period of time. This is driven by variable appearance and disappearance rates of the virus in different locations and the likelihood of ongoing community transmission, albeit at a lower rate as compared to the transmission rates observed during the initial outbreaks in China, Europe and the US. This means that the pandemic will not disappear within weeks or even months and will, therefore, have long-lasting effects on health systems, society and patient expectations. Considering the wider impact of the COVID-19 crisis, our societies, governments, and central banks have rapidly initiated measures to cushion the economic downturn while resources are allocated to manage the health crisis. Considering the magnitude of these challenges it is obvious that there will be long-lasting effects on all areas of society, including health systems, while we inoculate and prepare our societies for similar future events. From the perspective of gastroenterology, the COVID-19 pandemic has wide ranging implications. COVID-19 has direct effects on the gastrointestinal (GI) tract and the management of patients with GI and liver disease 3 . There is a need to manage the acute impact of the pandemic regarding staff and patient safety and to respond to potentially constrained resources related to competing health priorities. National and international guidelines or position statements (https://www.asge.org/home/joint-gi-society-message-covid-19 or https://www.esge.com/esge-and-esgena-position-statement-on-gastrointestinalendoscopy-and-the-covid-19-pandemic/) provide guidance, including recommendations on personal safety for the gastroenterologist and endoscopist through the use of specific personal protective equipment (PPE) including N95/FFP2 masks, on postponing non-urgent clinical, endoscopic and surgical services and on maintaining contact with patients through video and telephone virtual visits. However, it needs to be noted that most of these guidelines are drafted to meet the health system needs during the acute, early phase of the pandemic and it is evident that societies will have to cope with different phases of the COVID-19 crisis. All phases will present different challenges and require tailored responses by health systems and specialities. Thus, it is important to specifically characterise these different phases of the crisis ( Figure 1 ) and develop specific responses for the various phases of the crisis ( Table 1) . In the early phase of the response to the pandemic, the focus is to protect patients and staff while resources are made available to support the health system's response with regard to controlling the pandemic and treating COVID-19 cases. All such as endoscopy in the setting of the COVID-19 pandemic need to take into consideration the local situation. Such considerations should include, not just the local status of the pandemic, but also the local burden of non-COVID019 diseases and availability of resources. Guidelines or position statements that fail to provide a risk-stratified approach need to be interpreted with caution since they may not provide guidance that is appropriate for the local setting. While national and international guidelines should be taken into consideration, a variety of local and patient factors must be considered, including:  risk exposure of patients (probability of adverse outcomes) if a service or procedure is delayed;  risk exposure of staff related to uncontrolled community transmission of COVID-19 in Since the above factors might be highly variable across various demographic areas, decision making should be highly individualised, balancing risks and benefits. Besides these operational emergency responses, measures to manage stress and assist and support staff facing a potentially life-and death situation are important throughout the various phases. After the initial urgent emergency response (initiated by governments, health authorities, hospitals or individual clinicians) with reduction of endoscopic and consulting services, therecomes a realisation that core services are required to prevent avoidable adverse patient contacts, avoid nosocomial dissemination of the virus to patients and healthcare providers and at the same time maintain standard care for patients who require immediate attention…) 9 . It is obvious that the transition from the initial emergency response and the subsequent adaptation phase will be gradual and the boundaries between these phases might be sometimes blurred but the adaptation phase will focus on the rapid implementation of alternative service models. This phase is only now being tentatively initiated in some regions and it is likely that approaches will vary considerably and provide an opportunity for medical professionals and professional bodies to provide input and shape the response. It is already clear that two goals which may not be compatible will be operative at this stagethe desire, on the one hand, to mitigate viral dissemination and prevent its re-emergence and, on the other, to reopen economies and restore employment. While many changes are implemented rapidly to meet urgent patient needs or in order to reallocate resources to meet the demand of COVID-19 patients, it is critical that the impact of these changes are appropriately monitored. Thus, available quality frameworks need to be used (e.g. to monitor access to curtailed services or adverse outcomes) or new quality frameworks developed to ensure that novel modes of service delivery or techniques meet standards 10 . Ultimately the development of quality frameworks as early as possible will facilitate the trialling and implementation of quality frameworks. These frameworks will ensure that novel services deliver high value care 11 and the quality frameworks will enable a review of current practice innovations and allow research to further validate the implemented changes. This will be key to ensure that innovations developed during the crisis will be sustainable. Many expect that the interruptions of service delivery due to the COVID-19 pandemic will be temporary and that the consolidation phase will be short lived with rapid return to the 'pre-COVID-19 normal'. While this is a possible scenario, other developments are now more likely with long-term impact on clinical services. A key defining factor will be how fast the pandemic can be controlled globally. Given that herd immunity needs to develop, or that effective vaccines or antiviral therapies become available, this may well require considerably more time than optimists imagine. Furthermore, it has not yet been confirmed that effective protective immunity develops among recovered patients and re-infections have been observed after recovery from the initial infection 12 and the development of a safe and effective vaccine 13 or antiviral therapies 14 are not without challenges 13 . It is also evident that economies around the world will continue to face financial constraints which will impact on health care resources and may drive priorities. Overall, it must be anticipated that the ramifications for the delivery of services in the field of gastroenterology will be felt for a prolonged period. While resources may continue to be constrained, our clinics and endoscopy units will be confronted, at this stage, by an enormous backlog of patients whose clinical needs were not met during the initial phases of the pandemic. In this context most health systems will be required to rapidly innovate service delivery with the aim to most effectively utilise available resources. At the same time, service benefits can be maximised by prioritising patients who may experience the greatest benefit in outcomes. While in some (e.g. suspected celiac disease, eosinophilic oesophagitis, microscopic colitis or mild IBS) a delay in diagnosis and initiating treatment will not result in increased mortality, others will be exposed to substantial risk through such delay. In approximately 5% of patients with a single positive faecal occult blood tests (FOBT), a colon cancer can be found 15 and this number can be even higher in patients with two or three positive FOBT 15 . The substantial and most likely prolonged effects of the COVID-19 pandemic exposes patients to the risk of delayed diagnosis and treatment with subsequent excess morbidity and mortality. While a "best case" scenario suggests that all will magically return to normal when emergency measures are lifted, this will not happenrecovery and return to normal will be slow, stuttered and variable. Throughout this consolidation phase, whose duration is impossible to reliably forecast for all the aforementioned reasons, it will continue to be necessary to prioritise service delivery. While decisions regarding what constitutes an emergency may have been proven to be relatively easy in relation to the early phase, the prioritisation of care in this, much likely more prolonged consolidation phase, will present much greater challengesand ones that we must now give thought to. It is evident that the success of the system response with regard to the containment of the pandemic is critical for the overall impact of the pandemic in a given geographic area. However, the ability to contain the pandemic may still result in adverse outcomes of patients with non-COVID-19 related GI disease if gastroenterology does not provide the required specialty services in the aftermath of the COVID-19 crisis (Figure 2 ). In order to mitigate the effects of the COVID-19 pandemic, bold and cohesive responses of While curtailing services in the initial phase was, and continues to be, an appropriate measure to protect staff and patient safety, it is also essential that we plan now for the resumption of service delivery as soon as each local situation allows. Since COVID-19 will have long-lasting effects on health care systems, gastroenterologists need to rapidly develop strategies to most effectively meet patient needs or -at least -minimise risks during all phases of the COVID-19 pandemic when resources continue to be constrained ( Figure 2) . A variety of factors will determine the required responses. These factors include the rate of community transmission, the development of immunity, the availability of personal protective equipment and available resources. However, a variety of measures might be considered:  As early as possible, every Gastroenterologist, every Gastroenterology Department and every Hospital or Health Service should start to develop strategies on how to deliver the required services after the initial acute response phase. For this planning it is important to prepare for a variety of scenarios. The scenarios range from return to pre-COVID-19 levels of services within weeks to services that will be curtailed for months or even more than a year due to resource constraints and/or COVID-19-related restrictions.  While services might be curtailed due to constrained resources or other services reduced due to travel restrictions and the risk to staff and patients, the available resources should be utilised as efficiently as possible to meet community needs to avoid adverse patient outcomes and a backlog of urgent cases. where the provider and patient are not physically present with each other. While some of these services may initially be delivered over the phone (even though this is just an emergency measure and not a replacement for a face-to-face consultation), available technology should be used to close potential gaps between the traditional face-to-face consultation and the technology enabled service delivery. Proliferation and rapid refinement of videoconferencing technologies will make real-time face-to-face encounters as routine service modalities possible. Conversion to alternative modes is not limited to consultations delivered via phone or videoconferencing tools 16, 17 but equally for a variety of services relevant for the care of patients with highly prevalent GI diseases. This includes internet delivered cognitive behaviour therapy (iCBT) for patients with functional gastrointestinal disorders 18 as well as similar solutions in dietetic and other areas.  While there is the expectation that providers and their patients will rapidly recognise that these virtual visits do work and can provide substantial benefits, there is a need to accompany these transformations with robust quality assurance measures that capture not just the volume of encounters that have been delivered but ultimately compares relevant outcome parameters for traditional face-to-face vs. technology facilitated services.  System managers and funders, including public and private health insurances, should be required to fund alternative modes of service delivery and to eliminate or refine regulatory barriers to such modes of delivery.  While the COVID-19 crisis requires innovative and agile responses, it is important that all measures are embedded as soon as feasible into robust quality assurance or research frameworks. The delivery of services for patients with gastrointestinal disorders aims to reduce morbidity and mortality. While the impact of a delayed diagnosis of cancer can be readily quantified by outcome metrics, for other conditions these need to be developed and implemented 21, 22 .  Besides the development of remote patient care, standardisation and optimisation for regular outpatient services like infusion of biologics or monitoring of disease activity have to be considered in order to protect patients and staff from risks related to COVID-19. These may include re-organisation of infusion centres, home-based calprotectin or tough level measurement of drugs and the use of web-based apps to monitor disease activity 23 .  Numerous guidelines or recommendations have been produced to provide guidance in relation to PPE and safe delivery of services to patients during the COVID-19 pandemic 24 . Unfortunately, most of the recommendations are expert opinions and rarely based upon strong empiric evidence. As part of the consolidation phase, with most likely ongoing 'low level' epidemic, it is important to revisit these guidelines and update them with emerging new data.  Consumers need to be engaged and guided by appropriately tailored information to create an awareness about gastrointestinal symptoms or conditions that require urgent attention by a gastroenterologist to avoid adverse outcomes.  Judicious use of diagnostic exams and ancillary procedures so we do not stretch further a financially-and manpower-challenged healthcare system.  Gastroenterologists, in cooperation with other healthcare professionals, must initiate in their respective jurisdictions/countries a re-look at how we are going to be protected from present and future lawsuits in this telemedicine-based platforms of "the new normal of gastroenterology practice". The COVID-19 pandemic is major threat to human life and presents a challenge to the world community. All countries of the world are affected and health systems across the world rush to implement measures to contain the pandemic. While curtailing non-COVID-19 related services in virtually all regions of the world has been a part of the initial emergency response to the COVID-19 pandemic, it is highly likely that the post-acute COVID-19 crisis will be even more challenging. There is the risk that the death toll from COVID-19 will be exceeded by that from gastrointestinal diseases whose diagnoses and treatments were delayed or postponed. Temporarily curtailing gastroenterology services with a focus on maintaining only services for emergencies might be an appropriate response to the initial response to the COVID-19 crisis. While some may hope that COVID-19 will soon be eliminated, it is likely that the infection will coexist within our societies for a long period and this will impact on the ability to provide clinical services. Thus, Gastroenterologists now need to prepare for this scenario and unless steps are taken to proactively manage the transition to the 'new normal' it is likely that morbidity and mortality of patients with unattended GI disease could exceed the direct death toll from This article is protected by copyright.

In addition, it needs to be taken into consideration that curtailing services exposes patients to risks of having, in the short-or medium-term, excess morbidity and mortality. Furthermore, the societal costs associated with the containment of the pandemic and the subsequent economic implications need to be taken into consideration (Figure 3) . A focus on high value services will be a requirement to minimise the impact on vulnerable patient cohorts. It is critical that gastroenterologists anticipate various scenarios and act now proactively to develop responses to medium-and long-term challenges. While the COVID-19 situation is currently fluid, it can be anticipated that there will be considerable geographic differences. Thus, part of proactive planning is the need to develop local strategies to respond to the emerging challenges. While many of the responses may require bold and innovative solutions, it is critical that these measures are embedded whenever possible in appropriate quality assurance and research frameworks. While the objective to deliver quality services in a (cost-) efficient way has not changed, COVID-19 adds further challenges that will require us to refine, if not redesign, many areas of service delivery in Gastroenterology and Hepatology. The need to redesign services is a challenge but equally offers opportunities for accelerated development and introduction of new models of care. To rapidly recognise these opportunities and proactively respond to the obvious challenges is critical to mitigate risks to patients with gastrointestinal diseases in the aftermath of the COVID-19 pandemic. guidelines will emerge that guide service delivery for the emergency phase. The Consolidation phase is characterised by review and refinement of the services. Emphasis will be given to prioritisation of services. It is critical that the consolidation phase is accompanied by appropriate quality assurance and research activities to generate the evidence that is required to guide decision making in relation to service development.

The health system response is aimed towards rapid containment of the pandemic (while resources are made available for the treatment of COVID-19 patients). In the changed environment of the COVID-19 crisis, specilities such as Gastroenterology are required to adapt and innovate service models and prioritise service allocation to meet patient needs and mitigate risks. If specilities fail (or are unable) to develop mitigation strategies excess mobidity and mortality will be the consequence. Besides the innitial impact due to reduced capacity for urgent and emergency care, it can be expected that there will be excess morbidity and mortality due to underservicing of chronic conditions and delayed diganosis of malignancies. Subsequently it also can be expected that the economic consequences of the COVID-19 crisis will have long lasting adverse economic effects that have the potential to impact on service delivery for patients with gastrointestinal disorders.
