Determinants of patient trust in gastroenterology televisits: Results of machine learning analysis

Background The introduction of telemedicine into gastroenterology practice has been a major change over the past decade. Particularly during the COVID-19 pandemic, it has been very helpful for patients with chronic gastrointestinal disease as it has allowed continued healthcare delivery. Patient acceptance of televisits is key for its implementation in usual clinical practice, but lack of patient trust may limit its adoption. During the COVID-19 pandemic, we have embraced televisits instead of the traditional in-person medical examinations. The aim of the study was to evaluate the feasibility of televisits and factors influencing patient trust. Methods Patient trust in televisits was assessed through a validated questionnaire (PATAT). We employed machine learning (decision trees and random forests) in order to clearly understand the relationships between covariates influencing patient trust. Results Most televisits were successfully performed (186/218, 86.2%) and highly trusted (155/163, 95.2%). According to the decision tree, ‘The video service is easy to use’ in the parent node had the most influence on patient trust. Trust in the care organization, in the treatment, and in guaranteed data protection policies were the other factors influencing patient trust. In the random forest analysis, the use of known and user-friendly video services (12.8%IncMSE) and confidence in the data protection policies (12.4%IncMSE) were the two variables contributing most to trust in televisits. Conclusion Most patients with chronic gastrointestinal disease agreed to receive a televisit and trusted it. Knowledge of factors determining patient trust is essential to improve patient–doctor communication in order to increase the use of telemedicine in gastroenterology.

Infection Control Practices and Outcomes of Endoscopy Units in the Lombardy Region of Italy: A Survey From the Italian Society of Digestive Endoscopy During COVID-19 Spread.

GOALS: The present survey from the Italian Society of Digestive Endoscopy (SIED-Società Italiana di Endoscopia Digestiva) was aimed at reporting infection control practice and outcomes at Digestive Endoscopy Units in a high-incidence area. BACKGROUND: Lombardy was the Italian region with the highest coronavirus disease-2019 (COVID-19) prevalence, at the end of March 2020 accounting for 20% of all worldwide deaths. Joint Gastro-Intestinal societies released recommendations for Endoscopy Units to reduce the risk of the contagion. However, there are few data from high-prevalence areas on adherence to these recommendations and on their efficacy. METHODS: A survey was designed by the Lombardy section of SIED to analyze (a) changes in activity and organization, (b) adherence to recommendations, (c) rate of health care professionals' (HCP) infection during the COVID-19 outbreak. RESULTS: In total, 35/61 invited centers (57.4%) participated; most modified activities were according to recommendations and had filtering face piece 2/filtering face piece 3 and water-repellent gowns available, but few had negative-pressure rooms or provided telephonic follow-up; 15% of HCPs called in sick and 6% had confirmed COVID-19. There was a trend (P=0.07) toward different confirmed COVID-19 rates among endoscopists (7.9%), nurses (6.6%), intermediate-care technicians (3.4%), and administrative personnel (2.2%). There was no correlation between the rate of sick HCPs and COVID-19 incidence in the provinces and personal protective equipment availability and use, whereas an inverse correlation with hospital volume was found. CONCLUSIONS: Adherence to recommendations was rather good, though a minority were able to follow all recommendations. Confirmed COVID-19 seemed higher among endoscopists and nurses, suggesting that activities in the endoscopy rooms are at considerable viral spread risk.

Reopening Endoscopy after the COVID-19 Outbreak: Indications from a High Incidence Scenario.

Upper gastrointestinal bleeding in COVID-19 inpatients: Incidence and management in a multicenter experience from Northern Italy.

BACKGROUND: COVID-19 patients have an increased susceptibility to develop thrombotic complications, thus thromboprophylaxis is warranted which may increase risk of upper gastrointestinal bleeding (UGIB). Our aim was to evaluate incidence of UGIB and use of upper GI endoscopy in COVID-19 inpatients. METHODS: The medical and endoscopic management of UGIB in non-ICU COVID-19 patients has been retrospectively evaluated. Glasgow Blatchford score was calculated at onset of signs of GI bleeding. Timing between onset of signs of GI bleeding and execution, if performed, of upper GI endoscopy was evaluated. Endoscopic characteristics and outcome of patients were evaluated overall or according to the execution or not of an upper GI endoscopy before and after 24h. RESULTS: Out of 4871 COVID-19 positive patients, 23 presented signs of UGIB and were included in the study (incidence 0.47%). The majority (78%) were on anticoagulant therapy or thromboprophylaxis. In 11 patients (48%) upper GI endoscopy was performed within 24h, whereas it was not performed in 5. Peptic ulcer was the most common finding (8/18). Mortality rate was 21.7% for worsening of COVID-19 infection. Mortality and rebleeding were not different between patients having upper GI endoscopy before or after 24h/not performed. Glasgow Blatchford score was similar between the two groups (13;12-16 vs 12;9-15). CONCLUSION: Upper GI bleeding complicated hospital stay in almost 0.5% of COVID-19 patients and peptic ulcer disease is the most common finding. Conservative management could be an option in patients that are at high risk of respiratory complications.

Efficacy of endoscopic triage during the Covid-19 outbreak and infective risk.

OBJECTIVE: SARS-CoV-2 outbreak is spreading worldwide. As a consequence of the new circumstances, almost all endoscopic units underwent in-depth reorganization involving patients' selection. We analyzed the efficacy of the newly adopted endoscopic triage. METHODS: In March 2020, we monitored endoscopies to evaluate the effects of the novel selective triage aimed to reduce the number of investigations and viral spread/contagions. Clinical-demographic data of the patients, indications, type of endoscopy, endoscopic findings (subtyped in major and minor), finding rates (major and minor) and diagnostic yields (major findings) have been analyzed and compared to the endoscopic procedures performed in March 2019. Furthermore, patients were called at least 21 days after the endoscopy to evaluate the possibility of a Covid-19 onset. RESULTS: Accordingly to the novel triage, the number of procedures dropped from 530 to 91 (-84%). The finding rates and diagnostic yields were 83% (74-89) vs 71% (66-73) (P 0.015) and 56% (46-65) vs 43% (38-47) (P 0.03) on March 2020 and March 2019, respectively. A significant increase of operative procedures has been reported in 2020, 34% vs 22% in March 2019. All the patients were recalled and neither cases of onset of Covid-19 like symptoms nor positive nasopharyngeal swabs PCR have been evidenced. CONCLUSION: The novel endoscopic triage significantly reduced the number of procedures and increased finding rates and diagnostic yields. However, a careful schedule of canceled procedures should be applied to avoid to miss relevant pathologies. No Covid-19 onset or infection has been noted after endoscopies.

Endoscopic Findings in Patients Infected With 2019 Novel Coronavirus in Lombardy, Italy.

Coronavirus disease 2019 (COVID-19) is a major worldwide threat caused by a novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), rapidly spreading to a global pandemic. As of May 11, 2020, 4,176,346 cases have been reported worldwide, 219,814 in Italy, and of them, 81,871 occurred in the Lombardy region.1 Although the respiratory manifestations of COVID-19 have been widely described, the impact on the gastrointestinal (GI) system remains less clear. The reported prevalence of digestive symptoms ranges from 3% to 79%, depending on the setting,2-5 but data on GI endoscopic and histologic findings in COVID-19 patients are lacking. Therefore, the aim of this study is to describe the GI endoscopic and histologic findings in COVID-19 patients.

Endoscopy during the Covid-19 outbreak: experience and recommendations from a single center in a high-incidence scenario.

A dramatic SARS-Cov-2 outbreak is hitting Italy hard. To face the new scenario all the hospitals have been re-organised in order to reduce all the outpatient services and to devote almost all their personnel and resources to the management of Covid-19 patients. As a matter of fact, all the services have undergone a deep re-organization guided by: the necessity to reduce exams, to create an environment that helps reduce the virus spread, and to preserve the medical personnel from infection. In these days a re-organization of the endoscopic unit, sited in a high-incidence area, has been adopted, with changes to logistics, work organization and patients selection. With the present manuscript, we want to support gastroenterologists and endoscopists in the organization of a "new" endoscopy unit that responds to the "new" scenario, while remaining fully aware that resources, availability and local circumstances may extremely vary from unit to unit.
