Virtual Telesimulation for Medical Students During the COVID-19 Pandemic.

PROBLEM: In March 2020, the novel coronavirus 2019 (COVID-19) became a global pandemic. Medical schools around the United States faced difficult decisions, temporarily suspending hospital-based clerkship rotations for medical students due to potential shortages of personal protective equipment and a need to social distance. This decision created a need for innovative, virtual learning opportunities to support undergraduate medical education. APPROACH: Educators at Yale School of Medicine developed a novel medical student curriculum converting high-fidelity, mannequin-based simulation into a fully online virtual telesimulation format. By using a virtual videoconferencing platform to deliver remote telesimulation as an immersive educational experience for widely dispersed students, this novel technology retains the experiential strengths of simulation-based learning while complying with needs for social distancing during the pandemic. The curriculum comprises simulated clinical scenarios that include live patient actors; facilitator interactions; and real-time assessment of vital signs, labs, and imaging. Each 90-minute session includes 2 sets of simulation scenarios and faculty-led teledebriefs. A team of 3 students performs the first scenario, while an additional team of 3 students observes. Teams reverse roles for the second scenario. OUTCOMES: The 6-week virtual telesimulation elective enrolled the maximum 48 medical students and covered core clinical clerkship content areas. Communication patterns within the virtual telesimulation format required more deliberate turn-taking than normal conversation. Using the chat function within the videoconferencing platform allowed teams to complete simultaneous tasks. A nurse confederate provided cues not available in the virtual telesimulation format. NEXT STEPS: Rapid dissemination of this program, including online webinars and live demonstration sessions with student volunteers, supports the development of similar programs at other universities. Evaluation and process improvement efforts include planned qualitative evaluation of this new format to further understand and refine the learning experience. Future work is needed to evaluate clinical skill development in this educational modality.

Covid-19 and the N95 respirator shortage: Closing the gap.

Due to extreme shortages of personal protective equipment caused by the COVID-19 pandemic, many healthcare workers will be forced to recycle protective masks intended for disposal after a single use. We propose investigating the use of ultraviolet germicidal irradiation to sterilize masks of SARS-CoV-2 for safer reuse.

Multiple Fentanyl Overdoses - New Haven, Connecticut, June 23, 2016.

On the evening of June 23, 2016, a white powder advertised as cocaine was purchased off the streets from multiple sources and used by an unknown number of persons in New Haven, Connecticut. During a period of less than 8 hours, 12 patients were brought to the emergency department (ED) at Yale New Haven Hospital, experiencing signs and symptoms consistent with opioid overdose. The route of intoxication was not known, but presumed to be insufflation ("snorting") in most cases. Some patients required doses of the opioid antidote naloxone exceeding 4 mg (usual initial dose = 0.1-0.2 mg intravenously), and several patients who were alert after receiving naloxone subsequently developed respiratory failure. Nine patients were admitted to the hospital, including four to the intensive care unit (ICU); three required endotracheal intubation, and one required continuous naloxone infusion. Three patients died. The white powder was determined to be fentanyl, a drug 50 times more potent than heroin, and it included trace amounts of cocaine. The episode triggered rapid notification of public health and law enforcement agencies, interviews of patients and their family members to trace and limit further use or distribution of the fentanyl, immediate naloxone resupply and augmentation for emergency medical services (EMS) crews, public health alerts, and plans to accelerate naloxone distribution to opioid users and their friends and families. Effective communication and timely, coordinated, collaborative actions of community partners reduced the harm caused by this event and prevented potential subsequent episodes.

Toxic industrial chemicals and chemical weapons: exposure, identification, and management by syndrome.

Toxidromes aid emergency care providers in the context of the patient presenting with suspected poisoning, unexplained altered mental status, unknown hazardous materials or chemical weapons exposure, or the unknown overdose. The ability to capture an adequate chemical exposure history and to recognize toxidromes may reduce dependence on laboratory tests, speed time to delivery of specific antidote therapy, and improve selection of supportive care practices tailored to the etiologic agent. This article highlights elements of the exposure history and presents selected toxidromes that may be caused by toxic industrial chemicals and chemical weapons. Specific antidotes for toxidromes and points regarding their use, and special supportive measures, are presented.

The global burden of road injury: its relevance to the emergency physician.

Background. Road traffic crash fatalities in the United States are at the lowest level since 1950. The reduction in crash injury burden is attributed to several factors: public education and prevention programs, traffic safety policies and enforcement, improvements in vehicle design, and prehospital services coupled with emergency and acute trauma care. Globally, the disease burden of road traffic injuries is rising. In 1990, road traffic injuries ranked ninth in the ten leading causes of the global burden of disease. By 2030, estimates show that road traffic injuries will be the fifth leading causes of death in the world. Historically, emergency medicine has played a pivotal role in contributing to the success of the local, regional, and national traffic safety activities focused on crash and injury prevention. Objective. We report on the projected trend of the global burden of road traffic injuries and fatalities and describe ongoing global initiatives to reduce road traffic morbidity and mortality. Discussion. We present key domains where emergency medicine can contribute through international collaboration to address global road traffic-related morbidity and mortality. Conclusion. International collaborative programs and research offer important opportunities for emergency medicine physicians to make a meaningful impact on the global burden of disease.

Mass arsenic poisoning and the public health response in Maine.

Created in the wake of the September 11, 2001 terrorist attacks, Maine's Office of Public Health Emergency Preparedness within the Maine Center for Disease Control and Prevention undertook a major reorganization of epidemiology and laboratory services and began developing relationships with key partners and stakeholders, and a knowledgeable and skilled public health emergency preparedness workforce. In 2003, these newly implemented initiatives were tested extensively during a mass arsenic poisoning at the Gustav Adolph Lutheran Church in the rural northern community of New Sweden, Maine. This episode serves as a prominent marker of how increased preparedness capabilities, as demonstrated by the rapid identification and administration of antidotes and effective collaborations between key partners, can contribute to the management of broader public health emergencies in rural areas.

Use of haloperidol in PCP-intoxicated individuals.

CONTEXT: Emergency medical workers often experience violence while performing their job functions. Phencyclidine (PCP)-intoxicated patients are often violent and difficult to control physically. A chemical restraint is frequently needed to assist in protecting both patients and staff from agitated persons. OBJECTIVE: This study evaluated haloperidol as a chemical restraint in PCP-intoxicated patients. METHODS: This is a retrospective case series of all PCP-positive patients who received haloperidol for behavioral control from April 2008 to April 2011 at a single large (944 bed), urban, tertiary-care hospital. All patients receiving haloperidol and having a toxicology screen positive for PCP were identified using an electronic medical record. Identified cases were then manually reviewed by investigators for adverse events. RESULTS: Subjects included 59 adult patients who were acutely agitated requiring chemical restraint or sedation with haloperidol, and who tested positive for PCP. There were 20 females and 39 males, ranging in age from 19 to 54 years. Patients received haloperidol via the PO, IM, or IV routes in doses ranging from 1 to 10 mg. There were two adverse events (mild hypoxia and mild hypotension) found during chart review; neither were serious nor required change in patient disposition. CONCLUSIONS: In this study, haloperidol does not seem to cause harm when used in the management of PCP-intoxicated patients. Caution must always be exercised in the use of chemical restraint; further prospective study is warranted.

Expert consensus guidelines for stocking of antidotes in hospitals that provide emergency care.

STUDY OBJECTIVE: We developed recommendations for antidote stocking at hospitals that provide emergency care. METHODS: An expert panel representing diverse perspectives (clinical pharmacology, clinical toxicology, critical care medicine, clinical pharmacy, emergency medicine, internal medicine, pediatrics, poison centers, pulmonary medicine, and hospital accreditation) was formed to create recommendations for antidote stocking. Using a standardized summary of the medical literature, the primary reviewer for each antidote proposed guidelines for antidote stocking to the full panel. The panel used a formal iterative process to reach their recommendation for the quantity of an antidote that should be stocked and the acceptable period for delivery of each antidote. RESULTS: The panel recommended consideration of 24 antidotes for stocking. The panel recommended that 12 of the antidotes be available for immediate administration on patient arrival. In most hospitals, this period requires that the antidote be stocked in the emergency department. Another 9 antidotes were recommended for availability within 1 hour of the decision to administer, allowing the antidote to be stocked in the hospital pharmacy if the hospital has a mechanism for prompt delivery of antidotes. The panel identified additional antidotes that should be stocked by the hospital but are not usually needed within the first hour of treatment. The panel recommended that each hospital perform a formal antidote hazard vulnerability assessment to determine the need for antidote stocking in that hospital. CONCLUSION: The antidote expert recommendations provide a tool to be used in creating practices for appropriate and adequate antidote stocking in hospitals that provide emergency care.
