A narrative review on current duodenoscope reprocessing techniques and novel developments.

Duodenoscopy-associated infections occur worldwide despite strict adherence to reprocessing standards. The exact scope of the problem remains unknown because a standardized sampling protocol and uniform sampling techniques are lacking. The currently available multi-society protocol for microbial culturing by the Centers for Disease Control and Prevention, the United States Food and Drug Administration (FDA) and the American Society for Microbiology, published in 2018 is too laborious for broad clinical implementation. A more practical sampling protocol would result in increased accessibility and widespread implementation. This will aid to reduce the prevalence of duodenoscope contamination. To reduce the risk of duodenoscopy-associated pathogen transmission the FDA advised four supplemental reprocessing measures. These measures include double high-level disinfection, microbiological culturing and quarantine, ethylene oxide gas sterilization and liquid chemical sterilization. When the supplemental measures were advised in 2015 data evaluating their efficacy were sparse. Over the past five years data regarding the supplemental measures have become available that place the efficacy of the supplemental measures into context. As expected the advised supplemental measures have resulted in increased costs and reprocessing time. Unfortunately, it has also become clear that the efficacy of the supplemental measures falls short and that duodenoscope contamination remains a problem. There is a lot of research into new reprocessing methods and technical applications trying to solve the problem of duodenoscope contamination. Several promising developments such as single-use duodenoscopes, electrolyzed acidic water, and vaporized hydrogen peroxide plasma are already applied in a clinical setting.

Assessment of knowledge and implementation practices of the ventilator acquired pneumonia (VAP) bundle in the intensive care unit of a private hospital.

Studies have shown that a ventilator associated pneumonia (VAP) bundle significantly decreases VAP rates. In this study, we evaluated existing knowledge, practices, and adherence of nurses and infection control preventionists (ICP) to the VAP bundles of care in the intensive care unit (ICU) by using qualitative and quantitative tools. Of 60 participants (56 nurses and 4 ICPs), mean knowledge score regarding specific evidence-based VAP guidelines was 5 (range 3-8) out of 10 points. Self-reported adherence to the VAP bundle ranged from 38.5 to 100%, with perfect compliance to head of bed elevation, and poorest compliance with readiness to extubate. Overall VAP median bundle compliance was 84.6%. Knowledge regarding specific components of VAP prevention is lacking. Formal training and interactive educational sessions should be performed regularly to assess the competency of key personnel regarding the VAP bundle, especially in the context of rapid nurse turnover. Incentives for retention of nurses should also be considered, so that knowledge of hospital specific initiatives such as the VAP bundles of care can be cultivated over time.

BJS commission on surgery and perioperative care post-COVID-19.

BACKGROUND: Coronavirus disease 2019 (COVID-19) was declared a pandemic by the WHO on 11 March 2020 and global surgical practice was compromised. This Commission aimed to document and reflect on the changes seen in the surgical environment during the pandemic, by reviewing colleagues' experiences and published evidence. METHODS: In late 2020, BJS contacted colleagues across the global surgical community and asked them to describe how severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had affected their practice. In addition to this, the Commission undertook a literature review on the impact of COVID-19 on surgery and perioperative care. A thematic analysis was performed to identify the issues most frequently encountered by the correspondents, as well as the solutions and ideas suggested to address them. RESULTS: BJS received communications for this Commission from leading clinicians and academics across a variety of surgical specialties in every inhabited continent. The responses from all over the world provided insights into multiple facets of surgical practice from a governmental level to individual clinical practice and training. CONCLUSION: The COVID-19 pandemic has uncovered a variety of problems in healthcare systems, including negative impacts on surgical practice. Global surgical multidisciplinary teams are working collaboratively to address research questions about the future of surgery in the post-COVID-19 era. The COVID-19 pandemic is severely damaging surgical training. The establishment of a multidisciplinary ethics committee should be encouraged at all surgical oncology centres. Innovative leadership and collaboration is vital in the post-COVID-19 era.

A mixed-methods study describing behavioral factors that influenced general practitioners' experiences using triage during the COVID-19 pandemic.

BACKGROUND: Early in the COVID-19 pandemic, general practices were asked to expand triage and to reduce unnecessary face-to-face contact by prioritizing other consultation modes, e.g., online messaging, video, or telephone. The current study explores the potential barriers and facilitators general practitioners experienced to expanding triage systems and their attitudes towards triage during the COVID-19 pandemic. METHOD: A mixed-method study design was used in which a quantitative online survey was conducted along with qualitative interviews to gain a more nuanced appreciation for practitioners' experiences in the United Kingdom. The survey items were informed by the Theoretical Domains Framework so they would capture 14 behavioral factors that may influence whether practitioners use triage systems. Items were responded to using seven-point Likert scales. A median score was calculated for each item. The responses of participants identifying as part-owners and non-owners (i.e., "partner" vs. "non-partner" practitioners) were compared. The semi-structured interviews were conducted remotely and examined using Braun and Clark's thematic analysis. RESULTS: The survey was completed by 204 participants (66% Female). Most participants (83%) reported triaging patients. The items with the highest median scores captured the 'Knowledge,' 'Skills,' 'Social/Professional role and identity,' and 'Beliefs about capabilities' domains. The items with the lowest median scores captured the 'Beliefs about consequences,' 'Goals,' and 'Emotions' domains. For 14 of the 17 items, partner scores were higher than non-partner scores. All the qualitative interview participants relied on a phone triage system. Six broad themes were discovered: patient accessibility, confusions around what triage is, uncertainty and risk, relationships between service providers, job satisfaction, and the potential for total digital triage. Suggestions arose to optimize triage, such as ensuring there is sufficient time to conduct triage accurately and providing practical training to use triage efficiently. CONCLUSIONS: Many general practitioners are engaging with expanded triage systems, though more support is needed to achieve total triage across practices. Non-partner practitioners likely require more support to use the triage systems that practices take up. Additionally, practical support should be made available to help all practitioners manage the new risks and uncertainties they are likely to experience during non-face-to-face consultations.

SARS-CoV-2 screening among people living in homeless shelters in Brussels, Belgium.

BACKGROUND: Subgroups of precarious populations such as homeless people are more exposed to infection and at higher risk of developing severe forms of COVID-19 compared to the general population. Many of the recommended prevention measures, such as social distancing and self-isolation, are not feasible for a population living in shelters characterised by physical proximity and a high population density. The objective of the study was to describe SARS-CoV-2 infection prevalence in homeless shelters in Brussels (Belgium), and to identify risk factors and infection control practices associated with SARS-CoV-2 positivity rates. METHODS: A total of 1994 adults were tested by quantitative PCR tests in 52 shelters in Brussels (Belgium) between April and June, 2020, in collaboration with Doctors of the World. SARS-CoV-2 prevalence is here described site by site, and we identify risk factors associated with SARS-CoV-2 positivity rates. We also investigate associations between seropositivity and reported symptoms. RESULTS: We found an overall prevalence of 4.6% for the period, and a cluster of high rates of SARS-CoV-2 positivity (20-30% in two shelters). Among homeless people, being under 40 years of age (OR (CI95%) 2.3 (1.2-4.4), p = 0.02), having access to urgent medical care (AMU) (OR(CI95%): 2.4 (1.4-4.4)], p = 0.02), and sharing a room with someone who tested positive (OR(CI95%): 5.3 (2.9-9.9), p<0.0001) were factors associated with SARS-CoV-2 positivity rates. 93% of those who tested positive were asymptomatic. CONCLUSION: This study shows high rates of SARS-COV-2 infection positive tests in some shelters, with a high proportion of asymptomatic cases. The survey reveals how important testing and isolation measures are, together with actions taken by medical and social workers during the outbreak.

Assessment of a COVID-19 Control Plan on an Urban University Campus During a Second Wave of the Pandemic.

Importance: The COVID-19 pandemic has severely disrupted US educational institutions. Given potential adverse financial and psychosocial effects of campus closures, many institutions developed strategies to reopen campuses in the fall 2020 semester despite the ongoing threat of COVID-19. However, many institutions opted to have limited campus reopening to minimize potential risk of spread of SARS-CoV-2. Objective: To analyze how Boston University (BU) fully reopened its campus in the fall of 2020 and controlled COVID-19 transmission despite worsening transmission in Boston, Massachusetts. Design, Setting, and Participants: This multifaceted intervention case series was conducted at a large urban university campus in Boston, Massachusetts, during the fall 2020 semester. The BU response included a high-throughput SARS-CoV-2 polymerase chain reaction testing facility with capacity to deliver results in less than 24 hours; routine asymptomatic screening for COVID-19; daily health attestations; adherence monitoring and feedback; robust contact tracing, quarantine, and isolation in on-campus facilities; face mask use; enhanced hand hygiene; social distancing recommendations; dedensification of classrooms and public places; and enhancement of all building air systems. Data were analyzed from December 20, 2020, to January 31, 2021. Main Outcomes and Measures: SARS-CoV-2 diagnosis confirmed by reverse transcription-polymerase chain reaction of anterior nares specimens and sources of transmission, as determined through contact tracing. Results: Between August and December 2020, BU conducted more than 500 000 COVID-19 tests and identified 719 individuals with COVID-19, including 496 students (69.0%), 11 faculty (1.5%), and 212 staff (29.5%). Overall, 718 individuals, or 1.8% of the BU community, had test results positive for SARS-CoV-2. Of 837 close contacts traced, 86 individuals (10.3%) had test results positive for COVID-19. BU contact tracers identified a source of transmission for 370 individuals (51.5%), with 206 individuals (55.7%) identifying a non-BU source. Among 5 faculty and 84 staff with SARS-CoV-2 with a known source of infection, most reported a transmission source outside of BU (all 5 faculty members [100%] and 67 staff members [79.8%]). A BU source was identified by 108 of 183 undergraduate students with SARS-CoV-2 (59.0%) and 39 of 98 graduate students with SARS-CoV-2 (39.8%); notably, no transmission was traced to a classroom setting. Conclusions and Relevance: In this case series of COVID-19 transmission, BU used a coordinated strategy of testing, contact tracing, isolation, and quarantine, with robust management and oversight, to control COVID-19 transmission in an urban university setting.

A versatile web app for identifying the drivers of COVID-19 epidemics.

BACKGROUND: No versatile web app exists that allows epidemiologists and managers around the world to comprehensively analyze the impacts of COVID-19 mitigation. The http://covid-webapp.numerusinc.com/ web app presented here fills this gap. METHODS: Our web app uses a model that explicitly identifies susceptible, contact, latent, asymptomatic, symptomatic and recovered classes of individuals, and a parallel set of response classes, subject to lower pathogen-contact rates. The user inputs a CSV file of incidence and, if of interest, mortality rate data. A default set of parameters is available that can be overwritten through input or online entry, and a user-selected subset of these can be fitted to the model using maximum-likelihood estimation (MLE). Model fitting and forecasting intervals are specifiable and changes to parameters allow counterfactual and forecasting scenarios. Confidence or credible intervals can be generated using stochastic simulations, based on MLE values, or on an inputted CSV file containing Markov chain Monte Carlo (MCMC) estimates of one or more parameters. RESULTS: We illustrate the use of our web app in extracting social distancing, social relaxation, surveillance or virulence switching functions (i.e., time varying drivers) from the incidence and mortality rates of COVID-19 epidemics in Israel, South Africa, and England. The Israeli outbreak exhibits four distinct phases: initial outbreak, social distancing, social relaxation, and a second wave mitigation phase. An MCMC projection of this latter phase suggests the Israeli epidemic will continue to produce into late November an average of around 1500 new case per day, unless the population practices social-relaxation measures at least 5-fold below the level in August, which itself is 4-fold below the level at the start of July. Our analysis of the relatively late South African outbreak that became the world's fifth largest COVID-19 epidemic in July revealed that the decline through late July and early August was characterised by a social distancing driver operating at more than twice the per-capita applicable-disease-class (pc-adc) rate of the social relaxation driver. Our analysis of the relatively early English outbreak, identified a more than 2-fold improvement in surveillance over the course of the epidemic. It also identified a pc-adc social distancing rate in early August that, though nearly four times the pc-adc social relaxation rate, appeared to barely contain a second wave that would break out if social distancing was further relaxed. CONCLUSION: Our web app provides policy makers and health officers who have no epidemiological modelling or computer coding expertise with an invaluable tool for assessing the impacts of different outbreak mitigation policies and measures. This includes an ability to generate an epidemic-suppression or curve-flattening index that measures the intensity with which behavioural responses suppress or flatten the epidemic curve in the region under consideration.

ESSD Commentary on Dysphagia Management During COVID Pandemia.

Since the World Health Organization declared the COVID-19 pandemic a Global Public Health Emergency, experts in swallowing are seeking guidance on service delivery and clinical procedures. The European Society for Swallowing Disorders provides considerations to support experts in swallowing disorders in clinical practice. During the COVID-19 pandemic, assessment and treatment of patients with oropharyngeal dysphagia should be provided, while at the same time balancing risk of oropharyngeal complications with that of infection of patients and healthcare professionals involved in their management. Elective, non-urgent assessment may be temporarily postponed and patients are triaged to decide whether dysphagia assessment is necessary; instrumental assessment of swallowing is performed only if processing of the instruments can be guaranteed and clinical assessment has not provided enough diagnostic information for treatment prescription. Assessment and management of oropharyngeal dysphagia is a high-risk situation as it must be considered an aerosol-generating procedure. Personal protective equipment (PPE) should be used. Telepractice is encouraged and compensatory treatments are recommended.

EAES Recommendations for Recovery Plan in Minimally Invasive Surgery Amid COVID-19 Pandemic.

BACKGROUND: COVID-19 pandemic presented an unexpected challenge for the surgical community in general and Minimally Invasive Surgery (MIS) specialists in particular. This document aims to summarize recent evidence and experts' opinion and formulate recommendations to guide the surgical community on how to best organize the recovery plan for surgical activity across different sub-specialities after the COVID-19 pandemic. METHODS: Recommendations were developed through a Delphi process for establishment of expert consensus. Domain topics were formulated and subsequently subdivided into questions pertinent to different surgical specialities following the COVID-19 crisis. Sixty-five experts from 24 countries, representing the entire EAES board, were invited. Fifty clinicians and six engineers accepted the invitation and drafted statements based on specific key questions. Anonymous voting on the statements was performed until consensus was achieved, defined by at least 70% agreement. RESULTS: A total of 92 consensus statements were formulated with regard to safe resumption of surgery across eight domains, addressing general surgery, upper GI, lower GI, bariatrics, endocrine, HPB, abdominal wall and technology/research. The statements addressed elective and emergency services across all subspecialties with specific attention to the role of MIS during the recovery plan. Eighty-four of the statements were approved during the first round of Delphi voting (91.3%) and another 8 during the following round after substantial modification, resulting in a 100% consensus. CONCLUSION: The recommendations formulated by the EAES board establish a framework for resumption of surgery following COVID-19 pandemic with particular focus on the role of MIS across surgical specialities. The statements have the potential for wide application in the clinical setting, education activities and research work across different healthcare systems.

Examining Common Characteristics Among Healthcare Personnel Positive for COVID-19 and the Effectiveness of Healthcare Personnel Mask Use in Preventing COVID-19 in a Large Health System in Central Michigan.

The aim of this quality improvement project was to survey commonalities among healthcare personnel (HCP) who tested positive for COVID-19 and to evaluate the effectiveness the organizational intervention to require HCP wear masks throughout their shift. Information regarding the 40 HCP who tested positive for COVID-19 between the dates of March 18, 2020 and May 13, 2020 were included in the analysis. Nurses (n = 9) made up the majority of HCP positive for COVID-19. The most common types of symptoms reported were cough (n = 26), headache (n = 20), and fever (n = 13). Fourteen days after the requirement for HCP across the organization to wear masks throughout their shift was implemented, a 67% reduction in positive tests among HCP involved in a workplace exposure was observed.

Usefulness of COVID-19 screen-and-test approach in pregnant women: an experience from a country with low COVID-19 burden.

OBJECTIVES: Information on the usefulness of screen-and-test strategies of pregnant women for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is lacking. METHODS: We retrospectively reviewed the Ljubljana Maternity Hospital database and searched for pregnant women, who were admitted to the hospital between March 15 and May 16, 2020, for a planned procedure or hospitalization. Their medical records were examined and SARS-CoV-2 test results were retrieved. RESULTS: During the two-month period analyzed, there were a total of 265 scheduled admissions of pregnant women to our hospital. Two hundred two (76.2%) were tested for SARS-CoV-2 1 day prior to admission. All tested negative for SARS-CoV-2 RNA, regardless of having coronavirus disease 2019 (COVID-19)-compatible signs or symptoms (n=28) or not (n=174). CONCLUSIONS: In a population with a low SARS-CoV-2 burden, usefulness of universal testing of pregnant women before admission to the hospital is limited. We recommend that obstetric units in regions with low SARS-CoV-2 burden enforce rational use of personal protective equipment and diligent screening protocols using targeted questionnaires, whereas SARS-CoV-2 laboratory testing should be performed only in screen-positives: those with high clinical suspicion of COVID-19 and/or suspected epidemiological history.

Conocimiento y prácticas relacionadas con control y prevención de COVID-19 en trabajadores de la salud / Knowledge and practice regarding COVID-19 infection, control and prevention among healthcare workers

La enfermedad por coronavirus 2019 (COVID-19) ha afectado a los trabajadores de la salud (TS) quienes suman riesgo de exposición en la comunidad y el trabajo. El conocimiento y preparación son fundamentales, sin embargo, durante la pandemia se han suspendido las actividades presenciales de formación-capacitación. El objetivo de este estudio fue determinar si la educación en línea genera una diferencia en el conocimiento y práctica de prevención y control de infecciones (PCI) para la COVID-19 en TS. Previo consentimiento, se administró un cuestionario antes-después a los participantes de un curso de PCI en línea. Para la evaluación de conocimientos y prácticas se diseñaron preguntas tipo Likert con valores de 1 a 5, realizando el análisis con la prueba no paramétrica de rangos con signo de Wilcoxon para muestras relacionadas. En 345 participantes, la mediana fue 30 (RIC 15) años, femenino (224, 65%), residentes en el departamento de Guatemala (221, 57%), labora en sector público (155, 44.9%), sector privado (154, 44.6%), y seguro social (29, 8.4%). La evaluación antes-después mostró diferencia significativa de la brecha existente en el conocimiento y las prácticas de PCI (p < .05). La mayor brecha se observó en el autocuidado de la salud física, mental y nutricional. En las percepciones, uno de cada tres encuestados manifestó temor a sufrir estigma en caso de resultar infectados. La educación y entrenamiento en PCI es esencial ante una enfermedad altamente contagiosa que amenaza la salud y seguridad de los TS, principalmente en entornos sanitarios con recursos limitados.

The coronavirus disease 2019 (COVID-19) has affected health workers (HCWs) who adds risk of exposure in the community and at work. Knowledge and preparation are essential. However, during the pandemic, face-to-face training activities have been suspended. The objective of this study was to determine if online education generate a difference in the knowledge and practice of infection prevention and control (IPC) of COVID-19 in HCWs. With prior consent, a before-after questionnaire was administered to participants of an online PCI course. For the evaluation of knowledge and practices, Likert-type questions were designed with values from 1 to 5, performing the analysis with the non-parametric test of Wilcoxon signed ranges for related samples. In 345 participants, the median was 30 (IQR 15) years, female (224, 65%), living in the department of Guatemala (221, 57%), working in the public sector (155, 44.9%), private sector (154, 44.6%), and social security (29, 8.4%). The before-after assessment showed a significant difference in the gap between knowledge and practices. The largest gap was observed in self-care of physical, mental, and nutritional health. About perceptions, one out of every three respondents expressed fear of suffering stigma if they get infected. Education and training in IPC are essential in the face of a highly contagious disease that threatens the health and safety of HCWs, mainly in healthcare settings with limited resources.

Understanding the Psychological Impact of COVID-19 Pandemic on Patients With Cancer, Their Caregivers, and Health Care Workers in Singapore.

PURPOSE: The coronavirus disease 2019 (COVID-19) pandemic has had a global impact, and Singapore has seen 33,000 confirmed cases. Patients with cancer, their caregivers, and health care workers (HCWs) need to balance the challenges associated with COVID-19 while ensuring that cancer care is not compromised. This study aimed to evaluate the psychological effect of COVID-19 on these groups and the prevalence of burnout among HCWs. METHODS: A cross-sectional survey of patients, caregivers, and HCWs at the National Cancer Centre Singapore was performed over 17 days during the lockdown. The Generalized Anxiety Disorder-7 and Maslach Burnout Inventory were used to assess for anxiety and burnout, respectively. Self-reported fears related to COVID-19 were collected. RESULTS: A total of 624 patients, 408 caregivers, and 421 HCWs participated in the study, with a response rate of 84%, 88%, and 92% respectively. Sixty-six percent of patients, 72.8% of caregivers, and 41.6% of HCWs reported a high level of fear from COVID-19. The top concern of patients was the wide community spread of COVID-19. Caregivers were primarily worried about patients dying alone. HCWs were most worried about the relatively mild symptoms of COVID-19. The prevalence of anxiety was 19.1%, 22.5%, and 14.0% for patients, caregivers, and HCWs, respectively. Patients who were nongraduates and married, and caregivers who were married were more anxious. The prevalence of burnout in HCWs was 43.5%, with more anxious and fearful HCWs reporting higher burnout rates. CONCLUSION: Fears and anxiety related to COVID-19 are high. Burnout among HCWs is similar to rates reported prepandemic. An individualized approach to target the specific fears of each group will be crucial to maintain the well-being of these vulnerable groups and prevent burnout of HCWs.
