Extended reality (XR) modalities in health care are quickly evolving. There is a lack of systematically described developmental process and the "how to" execute a business-case guidance. This article formulates a systematic approach on the technical developmental steps and generation of business-case to guide the iterative development of an XR tool. An international expert group was established and several available frameworks related to entrepreneurship and business-case development were used to generate recommendations. Our ongoing experience with the development life cycle of an XR tool for cardiopulmonary resuscitation training is provided as a real-life case illustration. Market demand, value proposition, stakeholder analyses, and profitability scenarios are captured with a business model canvas. Developmental process is divided into 4 aspects: Desirability, Feasibility, Viability, and Scalability. Technical- and Investment Readiness Level models are used in defining the technical feasibility and the business viability and scalability, respectively. Best practice recommendations including examples are provided. Health care professionals, health care financers, and health care policymakers are urged to consider the provided systematic approach and recommendations prior to starting a venture with XR.

Despite a rapidly evolving role for advanced therapeutic interventions, the majority of patients with high-risk pulmonary embolism (PE) are still undertreated. Due to complex diagnosis and management, along with a high associated mortality rate, high-risk PE offers an excellent opportunity for simulation training. We present a simulated case of high-risk PE in a post-operative patient that is designed to teach key principles of diagnosis and management. The script is widely adaptable to many institutions and customisable to diverse learner populations.

Imaging plays a major role in the care of the intensive care unit (ICU) patients. An understanding of the monitoring devices is essential for the interpretation of imaging studies. An awareness of their expected locations aids in identifying complications in a timely manner. This review describes the imaging of ICU monitoring and support catheters, tubes, and pulmonary and cardiac devices, some more commonly encountered and others that have been introduced into clinical patient care more recently. Special focus will be placed on chest radiography and potential pitfalls encountered.

Cerebrospinal fluid (CSF) diversion for hydrocephalus via ventriculoperitoneal (VP) shunting is one of the most commonly performed neurosurgical procedures. Unfortunately, VP shunting also carries a high complication rate. While long-term complications of VP shunting are generally well-described, the literature on more acute, iatrogenic injury during shunt placement is essentially limited to easily identifiable intracranial bleeds. Herein is presented the first reported case of iatrogenic abdominal wall vessel injury as a consequence of blind distal VP shunt catheter placement causing a critical haemoperitoneum that necessitated multiple transfusions. Presentation and recognition of this bleed was delayed as it occurred over a number of days. Injury to the inferior epigastric artery, or potentially a distal branch of the superficial epigastric artery, is suspected to have occurred during either blind subcutaneous tunnelling of the shunt catheter passage or during penetration of the peritoneum. Haemoperitoneum as a potential complication of procedures involving manipulation or penetration of the abdominal wall (i.e. paracentesis) is well-described in the medical and general surgical literature, and ultrasound-guidance has been widely adopted to mitigate bleeding in these cases. Familiarity with intra-abdominal haemorrhage as a potential complication of VP shunting and an understanding of its presentation is critical for timely identification of this phenomenon. Furthermore, the use of real-time ultrasound-guidance for tunnelling and distal shunt catheter placement may decrease the incidence of intrabdominal complications after shunt placement more generally and should be considered an area of future study.

STATEMENT/UNASSIGNED:The dramatic outbreak of COVID-19 placed unprecedented strain on the critical care workforce of New York City. The enhanced precautions required to safely care for COVID-19 patients impacted the performance of even routine critical care procedures. Meanwhile, staff were stretched to care for exponentially rising case volume as COVID intensive care units (ICUs) expanded. Simulation was used to bridge these gaps-first to familiarize personnel within the Division of Pulmonary and Critical Care with revised COVID-19 care procedures, then to orient noncritical care clinicians volunteering from other specialties for COVID ICU deployment to general critical care and COVID-19 care principles. Using mannequin-based simulation scenarios followed by comprehensive debriefing sessions, simulation participants received high-intensity, high-fidelity training in respiratory failure, circulatory failure, bedside ultrasound, bedside ICU procedures, and elements of COVID-19-specific care. More than 200 physicians and advanced practice practitioners completed simulation training in preparation for deployment, supplementing and enhancing the ICU workforce at a decisive time during the outbreak.

PURPOSE/OBJECTIVE:The COVID-19 surge required the deployment of large numbers of non-intensive care providers to assist in the management of the critically ill. Institutions took a variety of approaches to "uptraining" such providers though studies describing methods and effectiveness are lacking. MATERIALS AND METHODS/METHODS:One hundred and seventy-five providers underwent a 3 h simulation-based session focused on management of shock, mechanical ventilation, acute respiratory distress syndrome, and critical care ultrasound. All participants were sent surveys to assess their comfort with various aspects of critical care following return to their usual work environments. RESULTS:One hundred and eight providers of 175 (62%) completed the survey. Overall, 104/108 responders (96%) felt training either significantly or somewhat improved their knowledge in the management of ICU patients. Responders felt most comfortable in the management of hypoxemia in intubated patients and the management of ventilated patients with acute respiratory distress syndrome (93% strongly agree or agree, and 86% strongly agree or agree, respectively). Fewer responders felt more comfortable using focused echocardiography (70% strongly agree or agree) and lung ultrasonography in following progression of COVID-19 (76% strongly agree or agree). CONCLUSIONS:Simulation-based training improved provider comfort in the management of critically ill patients with COVID-19.

INTRODUCTION/BACKGROUND:Rapid response teams (RRTs) have become ubiquitous among hospitals in North America, despite lack of robust evidence supporting their effectiveness. Many RRTs do not yet use cognitive aids during these high-stakes, low-frequency scenarios, and there are no standardized cognitive aids that are widely available for RRTs on medicine patients. We sought to design an emergency manual to improve resident performance in common RRT calls. METHODS:Residents from the New York University School of Medicine Internal Medicine Residency Program were asked to volunteer for the study. The intervention group was provided with a 2-minute scripted informational session on cognitive aids as well as access to a cognitive aid booklet, which they were allowed to use during the simulation. RESULTS:Resident performance was recorded and scored by a physician who was blinded to the purpose of the study using a predefined scoring card. Residents in the intervention group performed significantly better in the simulated RRT, by overall score (mean score = 7.33/10 and 6.26/10, respectively, P = 0.02), and by performance on the two critical interventions, giving the correct dose of naloxone (89% and 39%, respectively, P < 0.001) and checking the patient's blood glucose level (93% and 52%, respectively, P = 0.001). CONCLUSIONS:In a simulated scenario of opiate overdose, internal medicine residents who used a cognitive aid performed better on critical tasks than those residents who did not have a cognitive aid. The use of an appropriately designed cognitive aid with sufficient education could improve performance in critical scenarios.
