The Transitional Medical Model: An innovative methodology for a community's disease outbreak and pandemic preparedness and response plan.

Infectious disease outbreaks, epidemics, and subsequent pandemics are not typical disasters in the sense that they often lack clearly delineated phases. As in any event that is biological in nature, its onset may be gradual with signs and symptoms that are so subtle that they go unrecognized, thus missing opportunities to invoke an early response and implement containment strategies. An infectious disease outbreak-whether caused by a novel virus, a particularly virulent influenza strain, or newly emerging or resistant bacteria with the capability of human-to-human transmission-can quickly degrade a community's healthcare infrastructure in advance of coordinated mitigation, preparation, and response activities. The Transitional Medical Model (TMM) was developed to aid communities with these crucial phases of disaster response as well as to assist with the initial steps within the recovery phase. The TMM is a methodology that provides a crosswalk between the routine operations and activities of a community's public health infrastructure with action steps associated with the mitigation, preparedness, response, and recovery phases of an infectious disease outbreak.

What Do Emergency Department Patients and Their Guests Expect From Their Health Care Provider in an Active Shooter Event?

BACKGROUND: "Run-Hide-Fight" is the summative life-saving mantra taught by governmental and private agencies in active shooter training. Initial research focused on patient expectations of health care provider responses in life-threatening situations suggests patients believe health care providers will take significant action to protect patient well-being. The potential disparity between expectations of the public and health care practitioner training must be examined, as conflict, confusion, and delays may have mortal consequences in active shooter situations. OBJECTIVE: Public perceptions of the extent of health care practitioners' duties and responsibilities to themselves and their patients during an active shooter event were investigated. METHODS: A survey that queried perceived expectations of health care provider response efforts in 4 emergency department patient case scenarios interrupted by an active shooter event was developed and implemented to patients and retinue of the University of Toledo Emergency Department. Responses were grouped into provider-centric or patient-centric actions. RESULTS: One hundred twenty-seven participants responded to the survey and were included in the analysis: 82 patients and 45 guests. In all 4 scenarios, a mean of 87.4% responses was patient-centric. Frequency of patient-centric responses differed significantly by scenario, and women were more likely to have patient-centric expectations. DISCUSSION: The public has significant expectations that the health care provider will assist them during active shooter situations. Providing for the security of the health care provider and patient simultaneously is in conflict with common hospital crisis training. Efforts must be taken to bring patient expectations and provider training into greater alignment.

Active Shooter: What Would Health Care Students Do While Caring for Their Patients? Run? Hide? Or Fight?

OBJECTIVE: The aim of this study was to explore the clinical decisions that health care students would make if faced with an active shooter event while providing patient care. METHODS: A cross-sectional study design was used to survey 245 students from 6 different professional programs. Participants read 4 case-based scenarios, selected 1 of 4 actions in a multiple-choice format, and responded to an open-ended question. Demographic questions asked whether participants had been a victim of violence and whether they have taken a certified active shooter course. Statistical analysis included descriptive statistics and chi-square testing. RESULTS: For each case, most students chose "patient-centric" versus "provider-centric" actions (range: 66%-94% and 4%-17%, respectively). The gender of the patient made no difference in actions. Those who attended a certified active shooter course tended to act with more "provider-centric" concerns than those who did not take such a course. CONCLUSION: A significant majority of interprofessional health care students, when presented with specific case-scenarios, declared they would act to protect themselves and their patients during an active shooter event. This "patient-centric" attitude transcends the oversimplified "Run-Hide-Fight" axiom and must be addressed by all health care educational institutions.

Improving the improvisational pelvic circumferential compression technique for open-book pelvic fractures using a simulation model and a sphygmomanometer.

BACKGROUND: Open-book pelvic fractures are associated with significant mortality. Emergency management may require a commercial pelvic circumferential compression device to reduce the fracture and compress haemorrhaging pelvic vasculature. Standard, commercial, twin-sized bedsheets are acceptable should commercial devices be unavailable. However, obese victims or personnel with insufficient body strength may impede successful reduction. OBJECTIVE: To demonstrate the value of an improvisational windlass (intravenous pole) in improving the ability to reduce an open-book pelvic fracture. METHODS: The Institutional Review Board-approved study involved 28 diverse healthcare students and emergency medicine residents. Each participant's demographic information and physical characteristics were recorded. A METIman was prepared with knee and ankle binding and a sphygmomanometer set at 40 mm Hg placed over the symphysis pubis. Two-person teams were randomly selected to place a bedsheet at greater trochanter level and atop the sphygmomanometer. The bedsheet was secured with maximum effort by the pairs and the pressure recorded. Following this, the pairs inserted an intravenous pole in the knot and torqued the pole to maximum effort and a repeat pressure recorded. RESULTS: The mean increase in pressure using only the bedsheet was 106.43 mm Hg per team. With bedsheet and intravenous pole, the mean pressure increase was 351.79 mm Hg per team. The difference was statistically significant (independent samples t-test: t = 17.177, p < 0.001, 95% CI (216.65 to 274.07 mm Hg). There was no correlation between pressure increases and the individual physical characteristics of the subjects (r = - 0.183, p = 0.352). CONCLUSIONS: Regardless of personnel's physical attributes, the addition of an improvisational windlass to a pelvic circumferential compression bedsheet can improve the ability to reduce an open-book fracture, especially in obese victims.

Developing "Herd Immunity" in a Civilian Community Through Incorporation of "Just-In-Time" Tourniquet Application Training.

INTRODUCTION: Herd immunity, a concept normally applied in vaccinated populations, is a preventative measure to determine if a significant portion of a population can protect vulnerable individuals against a certain disease. Like vaccines, tourniquet education can be a form of herd immunity to protect vulnerable individuals in a population and prevent the loss of life from a peripheral hemorrhage. The authors have identified a deficiency in simple, quick, and effective hemorrhage control education. Therefore, to maximize herd immunity, the novel educational platform evaluates the efficacy of "Just-in-Time" (JiT) tourniquet application training. HYPOTHESIS/PROBLEM: The authors hypothesize that the utilization of JiT training will be effective in promoting both competence and confidence for individuals to utilize tourniquets in response to a disaster environment. METHODS: This Institutional Review Board-approved study recruited medical students who were trained in hemorrhage control measures at a Level 1 Trauma Center. Tourniquet training sessions were held, and naïve civilians received tourniquet education. The subjects received a five- to ten-minute lesson on indications, contraindications, and application techniques of commercial and improvisational tourniquets. Participants subsequently applied a tourniquet to an instructor's arm to demonstrate proper tourniquet application for a brachial artery hemorrhage. Pre- and post-educational surveys were completed to test participant competency and confidence. RESULTS: Of the 104 subjects who completed the course, 97 had no prior training in hemorrhage control techniques, including commercial and improvisational tourniquet application. The mean pre-test score was 2.27/5.00 and the mean post-test score was 4.38/5.00, P <.001 (n = 97). When queried "How competent would you feel applying a tourniquet (commercial or improvisational) on an individual with a bleeding wound?" 92/97 felt confident (95%), one felt less confident, and four felt no difference in confidence levels (P <.001). CONCLUSION: Just-in-Time training is an effective method in teaching naïve civilians proper tourniquet application. This platform could serve as an alternative to more extensive training programs and requires less time, costs, and resources. If a significant number of individuals in a local community can effectively apply a tourniquet in a disaster scenario, a "herd immunity" effect could be achieved to control peripheral hemorrhages.

Killer amoebas: Primary amoebic meningoencephalitis in a changing climate.

Primary amoebic meningoencephalitis (PAM) caused by Naegleria fowleri is a rare and deadly disease that requires prompt treatment with multiple therapies. Although N. fowleri previously was only found in warmer areas, climate change appears to be contributing to its geographic spread. Clinicians should consider PAM when faced with a patient with meningitis, especially if the patient participates in outdoor water activities or practices nasal rinsing.

START versus SALT Triage: Which is Preferred by the 21st Century Health Care Student?

IntroductionWhile the art and science of disaster triage continue to evolve, the education of the US health care student in matters pertaining to disaster preparedness and response remains stifled. Unfortunately, these students will be assuming major decision-making responsibilities regarding catastrophes that will be complicated by climate change, nuclear threats, global terrorism, and pandemics. Meanwhile, Sort, Assess, Life-Saving Interventions, Treatment, and/or Transport (SALT) triage is being advocated over the globally popular Simple Triage and Rapid Treatment (START) algorithm for multiple reasons: (1) it's an all-hazard approach; (2) it has four medical interventions; and (3) it has an additional triage color for victims with non-survivable injuries.Hypothesis/ProblemAs present-day threats become more ominous and health care education emphasizes the needs of vulnerable populations and palliative care, the authors hypothesize that, when given a choice, health care students will prefer SALT triage. METHODS: A convenience sample of 218 interprofessional, disaster-naïve health care students received just-in-time, unbiased education on both START and SALT triage systems. Students then completed a survey asking them to decide which triage system they believe would be most effective in their community. RESULTS: A total of 123 health care students (56.4%) preferred SALT while 95 (43.6%) preferred START; however, only the physician assistant students showed a statistically significantly preference (28 versus six, respectively; P=.042). Interestingly, there was also a statistically significant difference in preference by gender (Chi-square=5.02; P=.025) of the observed distribution versus expected distribution in SALT and START. The females preferred SALT (61.0%) while the males preferred START (55.9%).Among those who preferred START, START being easier to learn was the most important reason cited. Among those who preferred SALT, the most important reason cited was that the number of patient triage categories seemed more logical, comprehensible, and consistent with traditional medical care. CONCLUSION: While SALT's preference among females and physician assistant students was based on the addition of medical interventions and the provision of palliative care, START's preference was related to expediency. Based on this research, incorporating disaster concepts into US health care students' curricula encourages thoughtful consideration among the future health care leaders about the most effective approach to triage care. It is critical that further research be completed to determine, without reservation, which triage system will not only save the most lives but provide the most humane care to victims.Fink BN, Rega PP, Sexton ME, Wishner C.

Salivary protein changes in response to acute stress in medical residents performing advanced clinical simulations: a pilot proteomics study.

CONTEXT: Quantitative changes of salivary proteins due to acute stress were detected. OBJECTIVE: To explore protein markers of stress in saliva of eight medical residents who performed emergency medicine simulations. MATERIALS AND METHODS: Saliva was collected before the simulations, after the simulations, and following morning upon waking. Proteins were separated by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE), identified by mass spectrometry (MS), and relatively quantified by densitometry. RESULTS: Salivary alpha-amylase and S-type cystatins significantly increased, while the ∼26 kDa and low-molecular weight (MW) (<10 kDa) SDS-PAGE bands exhibited changes after stress. DISCUSSION AND CONCLUSION: Alpha-amylase and cystatins are potential salivary markers of acute stress, but further validation should be performed using larger sample populations.

Immersive simulation education: a novel approach to pandemic preparedness and response.

Pandemic management involves strategic and tactical concepts rarely experienced with other disasters. To comprehend the enormity of these tasks and experience the critical decision-making required, local public health and other stakeholders participate in tabletop and functional exercises. Students in Master of Public Health (MPH) programs not only rarely experience this educational format, but also are seldom afforded substantive time to appreciate the critical decision making that is unique to pandemics. An immersive semester-long simulation exercise was created to educate graduate public health students about pandemics. Students in a MPH course were divided into groups representing county health departments. During the semester, students collaborated and completed incident command training, received audio lectures, and materials concerning an imminent pandemic. The students then participated in the 2.5-hr facilitated tabletop exercises in the classroom. A survey was developed to assess their perceptions of the experience. Most students felt more knowledgeable afterward and thought that this training style was innovative, entertaining, educational, and recommended it to fellow students and colleagues. The students believed that delivering a tabletop exercise in this fashion was educational and entertaining. It gave the students a better appreciation of the role of public health in managing the complexities associated with pandemics.

A national survey of emergency nurses and avian influenza threat.

INTRODUCTION: The purpose of this study was to determine the perceived likelihood of emergency nurses reporting to work during an avian influenza outbreak, to consider options if nurses decided not to report work, and to explore Protection Motivation Theory constructs as predictors of reporting to work. METHODS: A descriptive, nonexperimental, cross-sectional survey of emergency nurses within the United States. RESULTS: A total of 332 nurses (46%) responded. Most emergency nurses (84%) reported they would report to work (1 in 6 would not). The likelihood of reporting to work differed by education level, nurses' avian influenza information sources, and nurses who had family living with them. Of the nurses who decided not to report to work, the majority were willing to provide health information (90%), administer vaccinations (82%), and triage (74%) neighbors/friends from home. One third of nurses had not attended a disaster-preparedness drill within the past year. Only 20% identified formal training while on the job as a source of avian influenza information. A third of emergency nurses would be worried about getting an avian influenza vaccination because of potential adverse effects. Protection Motivation Theory accounted for almost 40% of the variance of likelihood to report to work, with response costs being the largest predictor. DISCUSSION: Disaster drills, avian influenza job training, and vaccination education are necessary to prepare emergency nurses for an outbreak. The findings support emergency nurses' willingness to work from home if they are unable to report to work. This finding is new and may have implications for disaster planning, staffing, and ED operations.

An assessment of nurses' knowledge of botulism.

OBJECTIVE: To assess nurses' knowledge of botulism, a Centers for Disease Control Category A bioterrorism agent, one case of which constitutes an emergency. DESIGN: The study utilized survey research. SAMPLE: The cluster sample included 1,414 registered nurses. MEASURE: The survey gathered demographic data and nurses' knowledge of the background, manifestation and management of botulism. RESULTS: The mean percentage of correct answers for the sample was 25.95%, with a standard deviation (SD) of ±19.89%. Only 90 (6.3%) achieved 60% or more correct. Educational preparation, experience, specialty/area of practice and whether nurses had a class in disaster medicine were also examined and although differences were noted, none of these factors accounted for a score of 60% or above. CONCLUSIONS: The results of this study indicate the need for an assessment of the current education nurses receive about botulism.

The delivery of a health promotion intervention by a public health promotion specialist improves patient satisfaction in the emergency department.

OBJECTIVES: The objective was to introduce a public health promotion specialist (PHPS) into the hospital emergency department (ED) to provide a brief health promotion intervention to patients and to determine the effect of the initiative on patient satisfaction. METHODS: Patients in the intervention group were offered and received a 5- to 10-minute presentation about exercise, heart health, healthy eating on a budget, or weight control by a trained PHPS. Patients in the control group received usual ED care. Both groups completed the patient satisfaction instrument. Ordinal logistic regression models were used to compare the two groups on patient satisfaction questions and to identify predictors of the likelihood of patients referring others to the ED. RESULTS: Subjects in the intervention group were more likely to rate the services as great in areas of patient satisfaction such as provider listening, staff being friendly and helpful, comfort and safety, and privacy. Those in the intervention group were three times more likely than those in the control group to state that they would refer others to the ED. CONCLUSIONS: Health promotion and disease prevention interventions carried out by PHPS in the ED can improve patient satisfaction.

Considerations for the vertical evacuation of hospitalized patients under emergency conditions.

Hospitals and other healthcare institutions in the twenty-first century face myriad challenges to their survival against a number of threats from many sources. A number of those threats, eg, internal, external, accidental, or intentional, may require the prompt evacuation of both patients and staff Although rare, this possibility is becoming more frequent in the United States. Unfortunately, despite accrediting agencies' mandates, there is a profound paucity of strategic and tactical guidelines in the medical literature. The purpose of this article is to present a strategic methodology for evacuation, particularly emergent evacuation, within the National Incident Command System/Hospital Incident Command System framework and to explore the tactics that should be considered when relocating multiple patients in various degrees of medical compromise.

Single-Breath-Count Test: an important adjunct in the triaging of patients in a mass-casualty incident due to botulism.

Clostridium botulinum toxins, the most poisonous substance known to humankind, are considered to be a [US] Centers for Disease Control and Prevention Category A bioterrorist agent. Despite this concern, little has been published with regard to the tactical aspects of triaging a mass-casualty event involving botulism victims arriving at an emergency department. Because neuromuscular-ventilatory failure is a principal reason for botulism's early morbidity and mortality, using a quick and sensitive test to evaluate this possibility is imperative. The purpose of this article is to propose the adoption of the Single-Breath-Count Test (SBCT). The ease and validity of the use of the SBCT in evaluating complications associated with various neuromuscular disorders make it an attractive adjunct for triage during a mass-casualty incident due to botulism. While education, immune globulin, antitoxin, and invasive airway techniques are well-recognized steps in treating botulism, incorporating a time-honored technique such as the SBCT, will be an important addition to the triage process.
