]; it has already infected >5 m individuals claiming around 350k lives. Individuals in highly laden healthcare environments have higher infection risk [
]. Concrete data on SARS-CoV-2 transmission via aerosols are lacking; with the potential of faecal viral load of infected individuals surpassing that of aerosols [
], both upper & lower gastrointestinal (GI) endoscopies are considered high-risk procedures for disease transmission. Therefore, we read with interest the clinical commentary by Cennamo et al. on Redesign of a GI endoscopy unit during the COVID-19 emergency: A practical model [
Suspension of non-emergency endoscopies (elective, screening or even urgent/suspected cancer cases) has been widely employed to allow crucial utilisation of human and material resources to areas of immediate COVID-19 care, thus sparing both personal protective equipment (PPE) and medications e.g. midazolam and pethidine/fentanyl the midst of the pandemic. Additionally, meticulous donning & doffing of PPE and extensive cleaning of procedure rooms & equipment after each endoscopy are done at the expense of time, limiting the amount of procedures that can be performed in any allocated list. One can observe an increase in turn-around time of up to 60 min for deep cleaning, reducing total capacity by 50–70%! However, the scale of the macroeconomic impact and ability to deliver human-centred healthcare, considering the detriment of the psychological effect of delayed diagnosis of sinister GI conditions and management guidance in case of chronic conditions cannot be overstated. Furthermore, the growing digestive endoscopy waiting lists, and the potential of medicolegal litigations associated with it, should be taken into account.
Hence, focus should also be given to the use of well-established, minimal-contact, GI diagnostic modalities as a transition to a modern model of care is required. Telemonitoring or telemedicine (TM) facilitates the delivery of healthcare services by providing the transmission of diagnostic information and consultation opportunities at a distance without direct physical contact with an individual or patient. To this end, capsule endoscopy (CE) is a prime example; able to guide (even at the pre-pandemic era) a refined management pathway by rationalising [
the use of conventional/flexible endoscopy, it allows extra confidence in decision-making whilst safeguarding patient interests. The validity of pan-enteric CE for diagnosis, mucosal healing follow-up and/or treatment assessment in inflammatory bowel disease (IBD) has already been demonstrated [
]. To minimize risks while safeguarding ‘distancing’ until the situation changes, one should employ all the necessary precautions, including live or app-based, remotely guided testing.
Therefore, with the introduction of newest technologies such as wireless body sensors & mobile-cloud-assisted, tele-endoscopic systems patients can follow their daily routines during a spectrum of diagnostic procedures. Evidence has shown that e-consultations is an effective and safe tool that offers the opportunity of delivering care at a distance without direct physical contact with the patient, hence with little risk(s) of spreading infections. For example, in patients with liver cirrhosis a smartphone-based Stroop test has been validated for the diagnosis of covert hepatic encephalopathy [
]. Similarly, a “Patient Buddy App” that monitors symptoms such as weight gain along with medication adherence and daily sodium intake has shown potential to prevent hospital readmissions secondary to hepatic encephalopathy [
]. This intervention showed the ability for TM to reduce 30-d and 90-d readmissions. Additionally, studies have shown that TM enables integrated care for all patients with IBD, regardless of disease severity or medication use [
]. TM helps to educate patients on the importance of measuring physiological parameters and taking their medication. Furthermore, patients learn to recognise a change in themselves, evaluate the symptoms, implement a treatment strategy in collaboration with the medical team and evaluate the response to therapy.
Latest service innovations in CE delivery offer models, economically viable already in ‘pre-crisis’ situations, through extensive use of telehealth for patient interaction, data transfer & video analysis, central pooling of resources and overall minimal capital expenditure [
]. Establishing this modality provides a platform to rapidly adopt further innovation such as artificial intelligence (AI) video reading, allowing therefore stepwise automation from capsule ingestion up to immediate report creation [
]; This pandemic calls for a drastic change of our ‘conventional’ ways, Table 1. Non-contact or minimal-contact methods are already available, evidently COVID-19 pandemic will speed up further development of such methods.
