Disaster Triage Skills Training: An Introductory Virtual Simulation for Medical Students.

Background Disaster triage training equips learners with the critical skills to rapidly evaluate patients, yet few medical schools include formal triage training in their curriculum. Simulation exercises can successfully teach triage skills, but few studies have specifically evaluated online simulation to teach these skills to medical students. Aims We sought to develop and evaluate a largely asynchronous activity for senior medical students to practice their triage skills in an online format. Methods We developed an online, interactive triage exercise for fourth-year medical students. For the exercise, the student participants acted as triage officers for an emergency department (ED) at a large tertiary care center during an outbreak of a severe respiratory illness. Following the exercise, a faculty member led a debriefing session using a structured debriefing guide. Pre- and post-test educational assessments used a five-point Likert scale to capture the helpfulness of the exercise and their self-reported pre- and post-competency in triage. Change in self-reported competency was analyzed for statistical significance and effect size. Results Since May 2021, 33 senior medical students have completed this simulation and pre- and post-test educational assessments. Most students found the exercise "very" or "extremely" helpful for learning, with a mean of 4.61 (SD: ±0.67). Most students rated their pre-exercise competency as "beginner" or "developing" and their post-exercise competency as "developing" or "proficient" on a four-point rubric. The average increase in self-reported competency was 1.17 points (SD: ±0.62), yielding a statistically significant difference (p < 0.001) and large effect size (Hedges' g: 1.94). Conclusions We conclude that a virtual simulation can increase students' sense of competence in triage skills, using fewer resources than in-person simulation of disaster triage. As a next step, the simulation and the source code are publicly available for anyone to engage with the simulation or adapt it for their respective learners.

COVID-19 Pandemic Surge: After-Action Report of a Coalition of Emergency Departments in New York City.

The coronavirus disease (COVID-19) pandemic has stressed the US health care system in unprecedented ways. In March and April 2020, emergency departments (EDs) throughout New York City experienced high volumes and acuity related to the pandemic. Here, we present a structured after-action report of a coalition of 9 EDs within a hospital system in the New York City metropolitan area, with an emphasis on best practices developed during the prolonged surge as well as specific opportunities for growth. We report our experience in 6 key areas using a framework built around lessons learned. This report represents the most salient concepts related to our institutional after-action report, and those seemingly most relevant to our peer institutions dealing with similar circumstances.

Ethical, Legal, and Social Challenges in the Development and Implementation of Disaster Telemedicine.

In recent years, advances in communications technology and market factors have led to a substantial expansion of telemedicine practice. One potential use of telemedicine is in disaster response, both as a resource for responders as well as a direct link to patients. The advantages of using telehealth to assist in disaster response are accompanied by important questions related to social impact, ethical implications, and regulatory oversight. A narrative review of several of these issues is presented here. The next steps in the development of a robust disaster telemedicine system will include the development of best practices and ethical guidelines agreed upon by all stakeholders, as well as the development of public-private partnerships geared at providing the highest quality disaster telemedicine to the greatest possible number of patients.

Preparedness and response at long-term care facilities following Hurricane Sandy: A qualitative analysis of experiences and attitudes among staff and administrators.

BACKGROUND: In late 2012, Hurricane Sandy struck the eastern United States. Healthcare infrastructure in New York City-including long-term care facilities (LTCFs)-was affected significantly. The authors examined the impact of the storm on LTCFs 2 years after the event, using a qualitative approach consisting of a semistructured interview focused on preparedness and response. Important insights regarding preparedness and response may be lost by quantitative analysis or outcome measurement alone. During Sandy, individuals at LTCFs experienced the event in important subjective ways that, in aggregate, could lead to valuable insights about how facilities might mitigate future risks. The authors used data from a semistructured interview to generate hypotheses regarding the preparation and response of LTCFs. The interview tool was designed to help develop theories to explain why LTCF staff and administrators experienced the event in the way they did, and to use that data to inform future policy and research. METHODS: Representatives from LTCFs located in a heavily affected area of New York City were approached for participation in a semistructured interview. Interviews were digitally recorded and transcribed. Recurrent themes were coded based on time period (before, during, or after the storm) and content. A grounded theory approach was used to identify important themes related to the participants' experiences. RESULTS: A total of 21 interviews were conducted. Several overarching themes were identified, including a perception that facilities had not prepared for an event of such magnitude, of inefficient communication and logistics during evacuation, and of lack of easily identifiable or appropriate resources after the event. Access to electrical power emerged as a key identifier of recovery for most facilities. The experience had a substantial psychological impact on LTCF staff regardless of whether they evacuated or sheltered in place during the storm. CONCLUSION: Representatives from LTCFs affected by Sandy experienced the preparation, response, and recovery phases of the event with a unique perspective. Their insights offer evidence which can be used to generate testable hypothesis regarding similar events in the future, and can inform policy makers and facility administrators alike as they prepare for extreme weather events in similar settings. Results specifically suggest that LTCFs develop plans which carefully address the unique qualities of extreme weather events, including communication with local officials, evacuation and transfer needs in geographic areas with multiple facilities, and plans for the safe transfer of residents. Emergency managers at LTCFs should consider electrical power needs with the understanding that in extreme weather events, power failures can be more protracted than in other types of emergencies.

A Qualitative Study of Psychological Outcomes in Avalanche First Responders.

OBJECTIVES: We sought to characterize the mental health morbidity associated with avalanche rescue, and to generate hypotheses as to how such morbidity may be mitigated. MATERIALS AND METHODS: Avalanche first responders were recruited through online advertisements, social media, direct outreach, and e-mail solicitation. Thirteen subjects were selected for inclusion. Each subject participated in a semistructured interview. Transcripts were coded and thematically analyzed. RESULTS: Themes identified from interviews fell into three broad categories: long-term effects of rescue participation, assessments of psychological support, and recommendations for change. Symptoms of substance use disorder, depression, anxiety, panic, acute stress disorder, and posttraumatic stress disorder were evident in the interviews, as was evidence of adverse effects on subjects' personal relationships. Many respondents described a deficiency of formal psychological support for avalanche first responders, often limited to after-action debriefs of varying effectiveness. Nevertheless, subjects who received high-quality professional psychological support considered it helpful. Participants' suggestions for improvement focused on formalizing preincident psychological preparation and postincident support. CONCLUSIONS: Avalanche responders may experience long-lasting, work-related psychological effects. There is a paucity of effective psychological preparation and support for this population of first responders. Formal psychological support is positively received when available. Further study is required to evaluate particular interventions in this specific population.

Cross-sectional Survey of Long-Term Care Facilities in the Rockaway Peninsula: Preparedness and Response During Hurricane Sandy.

BACKGROUND: Few studies have described the challenges experienced by long-term care facilities (LTCFs) following Hurricane Sandy. This study examined LTCF preparedness and experiences during and after the storm. METHODS: A cross-sectional survey was conducted 2 years after Hurricane Sandy to assess LTCF demographics, preparation, and post-storm resources. Surveys were conducted at LTCFs located on the Rockaway Peninsula of New York City. All LTCFs located in a heavily affected area were approached. RESULTS: Of 29 facilities, 1 had closed, 5 did not respond, 9 declined to participate, and 14 participated, yielding a response rate of 50% for open facilities. Twenty-one percent of the facilities had preparations specifically for hurricanes. More than 70% of the facilities had lost electricity, heat, and telephone service, and one-half had evacuated. Twenty-one percent of the facilities reported not receiving any assistance and over one-half reported that relief resources did not meet their needs. CONCLUSIONS: Many LTCFs lacked plans specific to such a large-scale event. Since nearly all of the LTCFs in the region were affected, preexisting transportation and housing plans may have been inadequate. Future preparation could include hazard-specific planning and reliance on resources from a wider geographic area. Access to electricity emerged as a top priority.

Assessing Coagulation by Rotational Thromboelastometry (ROTEM) in Rivaroxaban-Anticoagulated Blood Using Hemostatic Agents.

Introduction The use of direct oral anticoagulants (DOACs) such as rivaroxaban (Xarelto) is increasingly common. However, therapies for reversing anticoagulation in the event of hemorrhage are limited. This study investigates the ability of hemostatic agents to improve the coagulation of rivaroxaban-anticoagulated blood, as measured by rotational thromboelastometry (ROTEM). Hypothesis/Problem If a chitosan-based hemostatic agent (Celox), which works independently of the clotting cascade, is applied to rivaroxaban-anticoagulated blood, it should improve coagulation by decreasing clotting time (CT), decreasing clot formation time (CFT), and increasing maximum clot firmness (MCF). If a kaolin-based hemostatic agent (QuikClot Combat Gauze), which works primarily by augmenting the clotting cascade upstream of factor Xa (FXa), is applied to rivaroxaban-anticoagulated blood, it will not be effective at improving coagulation. METHODS: Patients (age >18 years; non-pregnant) on rivaroxaban, presenting to the emergency department (ED) at two large, university-based medical centers, were recruited. Subjects (n=8) had blood drawn and analyzed using ROTEM with and without the presence of a kaolin-based and a chitosan-based hemostatic agent. The percentage of patients whose ROTEM parameters responded to the hemostatic agent and percent changes in coagulation parameters were calculated. RESULTS: Data points analyzed included: CT, CFT, and MCF. Of the samples treated with a kaolin-based hemostatic agent, seven (87.5%) showed reductions in CT, eight (100.0%) showed reductions in CFT, and six (75.0%) showed increases in MCF. The average percent change in CT, CFT, and MCF for all patients was 32.5% (Standard Deviation [SD]: 286; Range:-75.3 to 740.7%); -66.0% (SD:14.4; Range: -91.4 to -44.1%); and 4.70% (SD: 6.10; Range: -4.8 to 15.1%), respectively. The corresponding median percent changes were -68.1%, -64.0%, and 5.2%. Of samples treated with a chitosan-based agent, six (75.0%) showed reductions in CT, three (37.5%) showed reductions in CFT, and five (62.5%) showed increases in MCF. The average percent changes for CT, CFT, and MCF for all patients were 165.0% (SD: 629; Range:-96.9 to 1718.5%); 139.0% (SD: 174; Range: -83.3 to 348.0%); and -8.38% (SD: 32.7; Range:-88.7 to 10.4%), respectively. The corresponding median percent changes were -53.7%, 141.8%, and 3.0%. CONCLUSIONS: Rotational thromboelastometry detects changes in coagulation parameters caused by hemostatics applied to rivaroxaban-anticoagulated blood. These changes trended in the direction towards improved coagulability, suggesting that kaolin-based and chitosan-based hemostatics may be effective at improving coagulation in these patients.

A pilot study of solar water disinfection in the wilderness setting.

OBJECTIVE: Solar disinfection of water has been shown to be an effective treatment method in the developing world, but not specifically in a wilderness or survival setting. The current study sought to evaluate the technique using materials typically available in a wilderness or backcountry environment. METHODS: Untreated surface water from a stream in rural Costa Rica was disinfected using the solar disinfection (SODIS) method, using both standard containers as well as containers and materials more readily available to a wilderness traveler. RESULTS: Posttreatment samples using polyethylene terephthalate (PET) bottles, as well as Nalgene and Platypus water containers, showed similarly decreased levels of Escherichia coli and total coliforms. CONCLUSIONS: The SODIS technique may be applicable in the wilderness setting using tools commonly available in the backcountry. In this limited trial, specific types of containers common in wilderness settings demonstrated similar performance to the standard containers. With further study, solar disinfection in appropriate conditions may be included as a viable treatment option for wilderness water disinfection.

Core content for wilderness medicine fellowship training of emergency medicine graduates.

Wilderness medicine is the practice of resource-limited medicine under austere conditions. In 2003, the first wilderness medicine fellowship was established, and as of March 2013, a total of 12 wilderness medicine fellowships exist. In 2009 the American College of Emergency Physicians Wilderness Medicine Section created a Fellowship Subcommittee and Taskforce to bring together fellowship directors, associate directors, and other interested stakeholders to research and develop a standardized curriculum and core content for emergency medicine (EM)-based wilderness medicine fellowships. This paper describes the process and results of what became a 4-year project to articulate a standardized curriculum for wilderness medicine fellowships. The final product specifies the minimum core content that should be covered during a 1-year wilderness medicine fellowship. It also describes the structure, length, site, and program requirements for a wilderness medicine fellowship.
