Innovation in Delivering a Live, Virtual Cadaver Dissection Course.

SUMMARY: The availability of advanced telecommunication technology and the social restrictions introduced by a global pandemic have compelled the medical community to explore new avenues of surgical education. Although cadaver courses have long been a fundamental method for learning surgical anatomy and improving operative preparedness, the COVID-19 pandemic has made traditional dissections less practical. The need for quality virtual learning experiences motivated the authors to design and assess the feasibility of organizing a live, virtual upper extremity peripheral nerve cadaver dissection course. Three phases were critical when developing the course: preplanning, planning, and execution. The success of the live, virtual cadaver dissection depended not only on a detailed curriculum, but the technological audio-video-internet needs to effectively communicate and interact with the viewers. Virtual learning mitigates the risks of in-person dissection courses during a global pandemic and can be enhanced with interactive media (e.g., illustrations and schematics) to augment learning experiences.

Learners' Responses to a Virtual Cadaver Dissection Nerve Course in the COVID Era: A Survey Study.

Background Virtual education is an evolving method for teaching medical learners. During the coronavirus disease 2019 pandemic, remote learning has provided a replacement for conferences, lectures, and meetings, but has not been described as a method for conducting a cadaver dissection. We aim to demonstrate how learners perceive a virtual cadaver dissection as an alternative to live dissection. Methods A virtual cadaver dissection was performed to demonstrate several upper extremity nerve procedures. These procedures were livestreamed as part of an educational event with multimedia and interactive audience questions. Participants were queried both during and after the session regarding their perceptions of this teaching modality. Results Attendance of a virtual dissection held for three plastic surgery training institutions began at 100 and finished with 70 participants. Intrasession response rates from the audience varied between 68 and 75%, of which 75% strongly agreed that they were satisfied with the virtual environment. The audience strongly agreed or agreed that the addition of multimedia captions (88%), magnified video loupe views (82%), and split-screen multicast view (64%) was beneficial. Postsession response rate was 27%, and generally reflected a positive perspective about the content of the session. Conclusions Virtual cadaver dissection is an effective modality for teaching surgical procedures and can be enhanced through technologies such as video loupes and multiple camera perspectives. The audience viewed the virtual cadaver dissection as a beneficial adjunct to surgical education. This format may also make in-person cadaver courses more effective by improving visualization and allowing for anatomic references to be displayed synchronously.

What encourages people to carpool? A conceptual framework of carpooling psychological factors and research propositions

Carpooling brings benefits to carpool participants and the environment and society. Literature has called for a better understanding of psychological factors encouraging people to carpool however current research does not provide an in-depth psychological understanding of carpooling behaviour. This paper provides a review of psychological factors motivating drivers and passengers to carpool and identifies psychological theories appropriate for carpooling research. The Theory of Planned Behaviour and Norm-Activation Model were used as a priori theoretical frameworks to undertake a systematic literature review to identify important factors and relevant theories. Eighteen psychological factors were identified and classified as either common for drivers and passengers or specific to each group. In addition to the a priori frameworks, Consumer Perceived Value, Social Capital, and Technology Acceptance Model are considered the most appropriate for carpooling research. A conceptual framework and six research propositions were developed. Further, eight additional directions for future research were suggested including employing a variety of data collection methods to ensure rigour;collecting more data from non-Western countries for contextual veracity;exploring and testing psychological factors more deeply;and investigating the impact of COVID-19 on carpooling decisions. This paper contributes to theory through the development of the conceptual framework, identifying research propositions and providing additional research directions. The identified factors can be considered by researchers, matching agencies, and policy-makers to better promote carpooling.

Manifesto for healthcare simulation practice.

A pandemic has sent the world into chaos. It has not only upended our lives; hundreds of thousands of lives have already been tragically lost. The global crisis has been disruptive, even a threat, to healthcare simulation, affecting all aspects of operations from education to employment. While simulationists around the world have responded to this crisis, it has also provided a stimulus for the continued evolution of simulation. We have crafted a manifesto for action, incorporating a more comprehensive understanding of healthcare simulation, beyond tool, technique or experience, to understanding it now as a professional practice. Healthcare simulation as a practice forms the foundation for the three tenets comprising the manifesto: safety, advocacy and leadership. Using these three tenets, we can powerfully shape the resilience of healthcare simulation practice for now and for the future. Our call to action for all simulationists is to adopt a commitment to comprehensive safety, to advocate collaboratively and to lead ethically.

Increased time from physiological derangement to critical care admission associates with mortality.

BACKGROUND: Rapid response systems aim to achieve a timely response to the deteriorating patient; however, the existing literature varies on whether timing of escalation directly affects patient outcomes. Prior studies have been limited to using 'decision to admit' to critical care, or arrival in the emergency department as 'time zero', rather than the onset of physiological deterioration. The aim of this study is to establish if duration of abnormal physiology prior to critical care admission ['Score to Door' (STD) time] impacts on patient outcomes. METHODS: A retrospective cross-sectional analysis of data from pooled electronic medical records from a multi-site academic hospital was performed. All unplanned adult admissions to critical care from the ward with persistent physiological derangement [defined as sustained high National Early Warning Score (NEWS) > / = 7 that did not decrease below 5] were eligible for inclusion. The primary outcome was critical care mortality. Secondary outcomes were length of critical care admission and hospital mortality. The impact of STD time was adjusted for patient factors (demographics, sickness severity, frailty, and co-morbidity) and logistic factors (timing of high NEWS, and out of hours status) utilising logistic and linear regression models. RESULTS: Six hundred and thirty-two patients were included over the 4-year study period, 16.3% died in critical care. STD time demonstrated a small but significant association with critical care mortality [adjusted odds ratio of 1.02 (95% CI 1.0-1.04, p = 0.01)]. It was also associated with hospital mortality (adjusted OR 1.02, 95% CI 1.0-1.04, p = 0.026), and critical care length of stay. Each hour from onset of physiological derangement increased critical care length of stay by 1.2%. STD time was influenced by the initial NEWS, but not by logistic factors such as out-of-hours status, or pre-existing patient factors such as co-morbidity or frailty. CONCLUSION: In a strictly defined population of high NEWS patients, the time from onset of sustained physiological derangement to critical care admission was associated with increased critical care and hospital mortality. If corroborated in further studies, this cohort definition could be utilised alongside the 'Score to Door' concept as a clinical indicator within rapid response systems.

The ROX index has greater predictive validity than NEWS2 for deterioration in Covid-19.

BACKGROUND: Patients admitted to hospital with Covid-19 are at risk of deterioration. The National Early Warning Score (NEWS2) is widely recommended, however it's validity in Covid-19 is not established and indices more specific for respiratory failure may be more appropriate. We aim to describe the physiological antecedents to deterioration, test the predictive validity of NEWS2 and compare this to the ROX index ([SpO2/FiO2]/respiratory rate). METHOD: A single centre retrospective cohort study of adult patients who were admitted to a medical ward, between 1/3/20 and 30/5/20, with positive results for SARS-CoV-2 RNA. Physiological observations and the NEWS2 were extracted and analysed. The primary outcome was a composite of cardiac arrest, unplanned critical care admission or death within 24 hours. A generalized linear model was used to assess the association of physiological values, NEWS2 and ROX with the outcome. FINDINGS: The primary outcome occurred in 186 patients (26%). In the preceding 24 hours, deterioration was most marked in respiratory parameters, specifically in escalating oxygen requirement; tachypnoea was a late sign, whilst cardiovascular observations remained stable. The area under the receiver operating curve was 0.815 (95% CI 0.804-0.826) for NEWS2 and 0.848 (95% CI 0.837-0.858) for ROX. Applying the optimal level of ROX, the majority of patients triggered four hours earlier than with NEWS2 of 5. INTERPRETATION: NEWS2 may under-perform in Covid-19 due to intrinsic limitations of the design and the unique pathophysiology of the disease. A simple index utilising respiratory parameters can outperform NEWS2 in predicting the occurrence of adverse events.
