ABSTRACTObjectiveTo compare emergency department triage nurses’ time to triage and accuracy of a simulated mass casualty incident (MCI) population using a computerized version of CTAS or START systems.MethodsThis pilot study was a prospective trial using a convenience sample. A total of 20 ED triage nurses, 10 in each arm of the study, were recruited. The paper-based questionnaire contained nine simulated MCI vignettes. An expert panel arrived at consensuses on the wording of the vignettes and created a standard triage score from which to compare the study participants. Linear regression and chi-squared test were used to examine the time to triage and accuracy of triage, respectively.ResultsThe mean triage time for computerized CTAS (cCTAS) and START were 138 seconds/patient and 33 seconds/patient, respectively. The effect size due to triage method was 108 seconds/patient (95% CI 83-134 seconds/patient). The cumulative triage accuracy for the cCTAS and START tools were 70/90 (77.8%) and 65/90 (72.2%), respectively. The percent difference between cumulative triage was 6% (95% CI −19-8%).ConclusionsTriage nurses completed START triage 105 seconds/patient faster when compared to cCTAS triage and a similar level of accuracy between the two methods was achieved. However, when the typing time is taken into consideration cCTAS took 45 seconds/patient longer. The use of either CTAS or START in the ED during a MCI may be reasonable but choosing one method over another is not justified from this investigation.

AbstractIntroductionA high influx of patients during a mass-casualty incident (MCI) may disrupt patient flow in an already overcrowded emergency department (ED) that is functioning beyond its operating capacity. This pilot study examined the impact of a two-step ED triage model using Simple Triage and Rapid Treatment (START) for pre-triage, followed by triage with the Canadian Triage and Acuity Scale (CTAS), on patient flow during a MCI simulation exercise.Hypothesis/ProblemIt was hypothesized that there would be no difference in time intervals nor patient volumes at each patient-flow milestone.MethodsPhysicians and nurses participated in a computer-based tabletop disaster simulation exercise. Physicians were randomized into the intervention group using START, then CTAS, or the control group using START alone. Patient-flow milestones including time intervals and patient volumes from ED arrival to triage, ED arrival to bed assignment, ED arrival to physician assessment, and ED arrival to disposition decision were compared. Triage accuracy was compared for secondary purposes.ResultsThere were no significant differences in the time interval from ED arrival to triage (mean difference 108 seconds; 95% CI, -353 to 596 seconds; P=1.0), ED arrival to bed assignment (mean difference 362 seconds; 95% CI, -1,269 to 545 seconds; P=1.0), ED arrival to physician assessment (mean difference 31 seconds; 95% CI, -1,104 to 348 seconds; P=0.92), and ED arrival to disposition decision (mean difference 175 seconds; 95% CI, -1,650 to 1,300 seconds; P=1.0) between the two groups. There were no significant differences in the volume of patients to be triaged (32% vs 34%; 95% CI for the difference -16% to 21%; P=1.0), assigned a bed (16% vs 21%; 95% CI for the difference -11% to 20%; P=1.0), assessed by a physician (20% vs 22%; 95% CI for the difference -14% to 19%; P=1.0), and with a disposition decision (20% vs 9%; 95% CI for the difference -25% to 4%; P=.34) between the two groups. The accuracy of triage was similar in both groups (57% vs 70%; 95% CI for the difference -15% to 41%; P=.46).ConclusionExperienced triage nurses were able to apply CTAS effectively during a MCI simulation exercise. A two-step ED triage model using START, then CTAS, had similar patient flow and triage accuracy when compared to START alone.LeeJS, FrancJM.

Introduction:We opened a national conference in Australia with a surprise mass casualty simulation scenario of a van versus multiple persons outside the conference venue. The purpose of this exercise was to increase awareness of, and preparation for, mass casualty incident (MCI) events for the conference delegates who were paramedics, emergency department nurses, and doctors.Aim:The aim of the research is to understand whether a surprise MCI simulation is a useful way to increase knowledge and motivate preparedness.Methods:A survey hosted on Qualtrics was circulated to delegates via email. The survey was designed by the research team and had 38 questions about demographics and respondents’ experience with MCIs, as well as their perceptions of the simulation exercise. The questions were a mixture of 5-point Likert scales, multiple choice, and short answers.Results:The majority of respondents were clinicians (n = 66, 76%) and those who worked in emergency departments or the prehospital setting (n = 75, 86%). While the majority had not responded to an MCI in the past 5 years (n = 67, 77%), more than half (n = 50, 57%) had undertaken MCI training during this time. Overall, a vast majority of respondents found the simulation to be a worthwhile exercise that increased knowledge and preparedness. An overwhelming majority also reported that the simulation was relevant to practice, of high quality, and a useful way to teach about major incidents.Discussion:Our surprise major incident simulation was a fun and effective way to raise awareness and increase knowledge in prehospital and emergency department clinicians about MCI response. This approach to simulation can be easily replicated at relatively low cost and is, therefore, a useful solution to training a group of multidisciplinary health professionals outside of the workplace.

AbstractAt approximately 12:30 pm on Saturday September 21, 2013, armed assailants attacked the upscale Westgate shopping mall in the Westlands area of Nairobi, Kenya. Using the seven key Major Incident Medical Management and Support (MIMMS) principles, command, safety, communication, assessment, triage, treatment, and transport, the Aga Khan University Hospital, Nairobi (AKUH,N) emergency department (ED) successfully coordinated the reception and care of all the casualties brought to the hospital.This report describes the AKUH,N ED response to the first civilian mass-casualty shooting incident in Kenya, with the hope of informing the development and implementation of mass-casualty emergency preparedness plans by other EDs and hospitals in Kenya, appropriate for the local health care system.WachiraBW, AbdallaRO, WallisLA.

Mass casualty incident (MCI) can occur at any time and place and health care institutions must be prepared to deal with these incidents. Emergency department staff rarely learn how to triage MCI patients during their medical or nurse degrees, or through on-the-job training. This study aims to evaluate the effect of training and experience on the MCI triage performance of emergency personnel.Methodology: This was a cross-sectional prospective study that analyzed the performance of 94 emergency department staff on the triage classifications of 50 trauma patients, before and after a short training in MCI triage, while taking into account their academic background and work experience.Results: The participants were assigned initially to one of two groups: low experience if they had less than 5 years of practice, and high experience if they had more than 5 years of practice. In the low experience group, the initial accuracy was 45.76 percent, over triage 45.84 percent, and subtriage 8.38 percent. In the high experience group, the initial accuracy was 53.80 percent, over triage 37.66 percent, and sub triage 8.57 percent.Postintervention Results: In the low experience group, the post intervention accuracy was 63.57 percent, over triage 21.15 percent, and subtriage 15.30 percentage. In the high experience group, the post-intervention accuracy was 67.66 percentage, over triage 15.19 percentage, and subtriage 17.14 percentage.  Conclusion: Upon completion of this study, it can be concluded that MCI triage training significantly improved the performance of all those involved in the workshop and that experience plays an important role in MCI triage performance.

AbstractCarbon monoxide acute intoxication is a common cause of accidental poisoning in industrialized countries and sometimes it produces a real mass casualty incident. The incident described here occurred in a church in the province of Verona, when a group of people was exposed to carbon monoxide due to a heating system malfunction. Fifty-seven people went to the Emergency Department. The mean carboxyhemoglobin (COHb) level was 10.1±5.7% (range: 3-25%). The clinicians, after medical examination, decided to move 37 patients to hyperbaric chambers for hyperbaric oxygen (HBO) therapy. This is the first case report that highlights and analyses the logistic difficulties of managing a mass carbon monoxide poisoning in different health care settings, with a high influx of patients in an Emergency Department and a complex liaison between emergency services. This article shows how it is possible to manage a complex situation with good outcome. (Disaster Med Public Health Preparedness. 2017;11:251–255)

Objective: Search and rescue after mass casualty incidents relies on robust data infrastructure. Federal Emergency Management Agency (FEMA’s) Task Force 1 (TF1) trains its volunteers to locate and virtually tag scene incidents using a global positioning satellite (GPS) device programmed with markers for each incident (Iron Sights). The authors performed a pilot study comparing Iron Sights™ to a Wi-Fi-based real-time incident geolocation and virtual tagging dashboard (Panacea™) in creating a dynamic common operating picture.Design: Twenty-nine stations were placed at a predefined scene incident, each featuring a set of varying waypoint markers using standard FEMA/TF1 nomenclature. Two volunteers performed the experiment for both the Iron Sights and Panacea systems, digitally tagging all station waypoints.Setting: TF1 simulation training field. Main outcome measure(s): Metrics compared included GPS location precision, marker accuracy, and delay between scene sweep and common operational picture (COP) generation.Results: Two hundred and sixty-one waypoints were digitally tagged after excluding three stations for missing data. The average GPS location difference for all waypoints between Iron Sights and Panacea was 3.65 m. Marker tagging accuracy between Iron Sights and Panacea was equivalent and not statistically different (78.8 percent vs 66.2 percent, respectively, p = 0.11). Waypoints were tagged in 26.59 minutes and 10.55 minutes on average, respectively. Time from scene sweep to virtual COP generation was 7.97 minutes for Iron Sights after complete scene sweep and 37 seconds for Panacea for each waypoint posting in real-time.Conclusions: Panacea generated the COP in real-time compared to a delay with Iron Sights while maintaining the same location precision and marker accuracy. This pilot trial successfully demonstrated the ability to provide real-time actionable intelligence to incident commanders during mass casualty search and rescue missions. Larger field trials are recommended to refine the system and broaden its capabilities.

Introduction:After a 6.0 magnitude earthquake struck Hualien on February 6, 2018, over one hundred and fifty patients crammed into the emergency department of a nearby tertiary hospital within two hours. The mass casualty incident (MCI) call was activated, and over 300 related personnel responded to the call and engaged with the MCI management.Aim:This research aimed to analyze the practice of an MCI call and to form the strategies to improve its efficiency and effectiveness.Methods:The research was conducted in a tertiary hospital in Hualien, Taiwan. Questionnaires regarding the practice of the MCI call were sent out to the healthcare providers in the emergency department who responded to that MCI operation.Results:Thirty-seven responders in the emergency department were involved in this study. 78% had participated in training courses for hospital incident command system (HICS) or MCI management before this event. On arrival at the emergency department, 69.4% of the responders were aware of the check-in station and received a clear task assignment and briefing. During the operation, 25.7% reported the lack of confidence carrying out the assigned tasks and 54.1% of the participants experienced great stress (stress score over 7 out of 10).Discussion:MCI is an uncommon event for hospital management. It is universally challenging owing to its unpredictable and time-sensitive nature. Furthermore, the administration could be further complicated by the associated disasters. Despite regular exercises and drills, there are still a significant number of participants experiencing stress and confusion during the operation. The chaotic situation may further compromise the performance of the participants. This study showed that optimizing task briefing and on-site directions may improve the performance of the MCI participants.
