Frequency, Type, and Degree of Potential Harm of Adverse Safety Events among Pediatric Emergency Medical Services Encounters.

BACKGROUND: Only 5-10% of emergency medical services (EMS) patients are children, and most pediatric encounters are low-acuity. EMS chart review has been used to identify adverse safety events (ASEs) in high-acuity and high-risk pediatric encounters. The objective of this work was to evaluate the frequency, type, and potential harm of ASEs in varied acuity pediatric EMS encounters. METHODS: This cross-sectional study evaluated pediatric (ages 0-18 years) prehospital records from 15 EMS agencies among three states (Colorado, Connecticut, and Rhode Island) between November 2019 and October 2021. Research associates used a previously validated tool to analyze electronic EMS and hospital records. Adverse safety events were recorded in six care categories, grouped into four levels for analysis: assessment/diagnosis/clinical decision-making, procedures, medication administration (including O2), and fluid administration, and defined across five types of ASEs: Unintended injuries or consequences, Near misses, Suboptimal actions, Errors, and Management complications (UNSEMs). Type and frequency of ASEs in each category were rated in three harm severities: Harm Unlikely, Mild/Temporary, or Permanent/Severe. Three physicians verified ASEs determined by research associates. Frequency of ASEs and harm likelihood are reported. RESULTS: Records for 508 EMS patients were reviewed, with 63 (12.4%) transported using lights and sirens. At least one clinical intervention beyond assessment/diagnosis/clinical decision-making was documented for 183 (36.1%, 95% CI: 31.8, 40.4) patients. A total of 162 ASEs were identified for 112 patients (22.1%, 95% CI: 18.5, 25.7). Suboptimal actions were the most frequent UNSEM (n = 66, 40.7%; 95% CI: 33.1, 48.3). For ASEs, (n = 162), the most frequent associations were with procedures 39.5% (95% CI: 32.0, 47.0) or assessment/diagnosis/clinical decision making, 32.1%, (95% CI: 24.9, 39.3). Among care categories, fluid administration was associated with significantly more UNSEMs (58.1%, 95% CI:53.8, 62.4). Most ASEs were determined to be 'Harm Unlikely' 62.4% (95% CI: 54.4, 70.4), with assessment/diagnosis/clinical decision making having significantly fewer ASEs with documented harm (22.4%, 95% CI: 10.7, 34.1) compared to other care categories. CONCLUSION: Over 20% of pediatric EMS encounters had an identified ASE, and most were unlikely to cause harm. Most frequent ASEs were likely to be associated with procedures and assessment/diagnosis/clinical decision-making.

An Evaluation of Prehospital Adenosine Use.

BACKGROUND: Adenosine has been safely used by paramedics for the treatment of stable supraventricular tachycardia since the mid-1990s. However, there continues to be variability in paramedics' ability to identify appropriate indications for adenosine administration. As the first of a planned series of studies aimed at improving the accuracy of SVT diagnosis and successful administration of adenosine by paramedics, this study details the current usage patterns of adenosine by paramedics. METHODS: This cross-sectional retrospective study investigated adenosine use within a large northeast EMS region from January 1, 2019, through September 30, 2021. Excluding pediatric and duplicate case reports, we created a dataset containing patient age, sex, and vital signs before, during, and after adenosine administration; intravenous line location; and coded medical history from paramedic narrative documentation, including a history of atrial fibrillation, suspected arrhythmia diagnosis, and effect of adenosine. In cases with available prehospital electrocardiograms (EKGs) for review, two physicians independently coded the arrhythmia diagnosis and outcome of adenosine administration. Statistical analysis included interrater reliability with Cohen's kappa statistic. RESULTS: One hundred eighty-three cases were included for final analysis, 84 did not have a documented EKG for review. Categorization of presenting rhythms in these cases occurred by a physician reviewing EMS narrative and documentation. Forty of these 84 cases (48%) were adjudicated as SVT likely, 32 (38%) as SVT unlikely and 12 (14%) as uncategorized due to lack of supporting documentation. Of the 99 cases with EKGs available to review, there was substantial agreement of arrhythmia diagnosis interpretation between physician reviewers (Cohen's kappa 0.77-1.0); 54 cases were adjudicated as SVT by two physician reviewers. Other identified cardiac rhythms included atrial fibrillation (16), sinus tachycardia (11), and ventricular tachycardia (2). Adenosine cardioversion occurred in 47 of the 99 cases with EKGs available for physician review (47.5%). Adenosine cardioversion was also deemed to occur in 87% (47/54) of cases when the EKG rhythm was physician adjudicated SVT. CONCLUSIONS: This study supports the use of adenosine as a prehospital treatment for SVT while highlighting the need for continued efforts to improve paramedics' identification and management of tachyarrhythmias.

Medication Dosing Safety for Pediatric Patients: Recognizing Gaps, Safety Threats, and Best Practices in the Emergency Medical Services Setting. A Position Statement and Resource Document from NAEMSP.

BACKGROUND: Millions of patients receive medications in the Emergency Medical Services (EMS) setting annually, and dosing safety is critically important. The need for weight-based dosing in pediatric patients and variability in medication concentrations available in the EMS setting may require EMS providers to perform complex calculations to derive the appropriate dose to deliver. These factors can significantly increase the risk for harm when dose calculations are inaccurate or incorrect. METHODS: We conducted a scoping review of the EMS, interfacility transport and emergency medicine literature regarding pediatric medication dosing safety. A priori, the authors identified four research topics: (1) what are the greatest safety threats that result in significant dosing errors that potentially result in harm to patients, (2) what practices or technologies are known to enhance dosing safety, (3) can data from other settings be extrapolated to the EMS environment to inform dosing safety, and (4) what impact could standardization of medication formularies have on enhancing dosing safety. To address these topics, 17 PICO (Patient, Intervention, Comparison, Outcome) questions were developed and a literature search was performed. RESULTS: After applying exclusion criteria, 70 articles were reviewed. The methods for the investigation, findings from these articles and how they inform EMS medication dosing safety are summarized here. This review yielded 11 recommendations to improve safety of medication delivery in the EMS setting. CONCLUSION: These recommendations are summarized in the National Association of EMS Physicians® position statement: Medication Dosing Safety for Pediatric Patients in Emergency Medical Services.

Sound and Air: Ultrasonographic Measurements of Pediatric Chest Wall Thickness and Implications for Needle Decompression of Tension Pneumothorax.

OBJECTIVES: Needle decompression is potentially life-saving in cases of tension pneumothorax. Although Advanced Trauma Life Support recommends an 8-cm needle for decompression for adults, no detailed pediatric guidelines exist, specifically regarding needle length or site of decompression. METHODS: Point-of-care ultrasound was used to measure chest wall thickness (CWT), the distance between skin and pleural line, bilaterally at the second intercostal midclavicular line and the fourth intercostal anterior axillary line in children of various ages and sizes. Patients were grouped based on Broselow tape weight categories. Measurements were compared between left versus right sides at the 2 anatomic sites. Interclass correlation coefficients were calculated to assess for interrater reliability. RESULTS: A convenience sample of 163 patients from our emergency department was enrolled. For patients who fit into Broselow tape categories, CWT at the second intercostal midclavicular line ranged from 1.11 to 1.91 cm and at the fourth intercostal anterior axillary line ranged from 1.13 to 1.92 cm. In patients larger than the largest Broselow category, 77% had a CWT less than the length of a standard 1.25-in (3.175 cm) catheter. There were no significant differences in the measurements of CWT based on laterality nor anatomic site. CONCLUSIONS: The standard 1.25-in (3.175 cm) catheters are sufficient to treat most tension pneumothoraces in pediatric patients.

Comparative Effectiveness of Analgesics to Reduce Acute Pain in the Prehospital Setting.

Objectives: The objectives of this study were to assess comparative effectiveness and harms of opioid and nonopioid analgesics for the treatment of moderate to severe acute pain in the prehospital setting. Methods: We searched MEDLINE®, Embase®, and Cochrane Central from the earliest date through May 9, 2019. Two investigators screened abstracts, reviewed full-text files, abstracted data, and assessed study level risk of bias. We performed meta-analyses when appropriate. Conclusions were made with consideration of established clinically important differences and we graded each conclusion's strength of evidence (SOE). Results: We included 52 randomized controlled trials and 13 observational studies. Due to the absence or insufficiency of prehospital evidence we based conclusions for initial analgesia on indirect evidence from the emergency department setting. As initial analgesics, there is no evidence of a clinically important difference in the change of pain scores with opioids vs. ketamine administered primarily intravenously (IV) (low SOE), IV acetaminophen (APAP) (low SOE), or nonsteroidal anti-inflammatory drugs (NSAIDs) administered primarily IV (moderate SOE). The combined use of an opioid and ketamine, administered primarily IV, may reduce pain more than an opioid alone at 15 and 30 minutes (low SOE). Opioids may cause fewer adverse events than ketamine (low SOE) when primarily administered intranasally. Opioids cause less dizziness than ketamine (low SOE) but may increase the risk of respiratory depression compared with ketamine (low SOE), primarily administered IV. Opioids cause more dizziness (moderate SOE) and may cause more adverse events than APAP (low SOE), both administered IV, but there is no evidence of a clinically important difference in hypotension (low SOE). Opioids may cause more adverse events and more drowsiness than NSAIDs (low SOE), both administered primarily IV. Conclusions: As initial analgesia, opioids are no different than ketamine, APAP, and NSAIDs in reducing acute pain in the prehospital setting. Opioids may cause fewer total side effects than ketamine, but more than APAP or NSAIDs. Combining an opioid and ketamine may reduce acute pain more than an opioid alone but comparative harms are uncertain. When initial morphine is inadequate, giving ketamine may provide greater and quicker acute pain relief than giving additional morphine, although comparative harms are uncertain. Due to indirectness, strength of evidence is generally low, and future research in the prehospital setting is needed.

Automated External Defibrillators in High Schools: Disparities Persist Despite Legislation.

OBJECTIVES: Automated external defibrillators (AEDs) have demonstrated increased survival in out-of-hospital cardiac arrest, and their prevalence continues to rise. In 2009, Connecticut passed a legislation requiring all schools to have an AED, barring financial barriers. The objectives of this study were (1) to determine if this legislation was associated with an increase in Connecticut high school AEDs and (2) to detect disparities in the availability of AEDs based on school type, student demographics, and school size. STUDY DESIGN: A single researcher conducted a scripted telephone survey of all 54 public and 13 private high schools in New Haven County, Connecticut. RESULTS: A response rate of 100% was achieved. Forty-nine percent of high schools had an AED before the legislation, compared with 88% after (P < 0.001). Before legislation, private schools had a higher percentage of AEDs than public schools (69% vs 44%; P = 0.1). Postlegislation, the difference is less (92% vs 87%; P = 0.4). Small schools (<400 students) are significantly less likely to have an AED than larger schools (40% vs 100%; P < 0.001). Schools with a higher percentage of students with disabilities are also less likely to have an AED (P = 0.005), even when controlling for school size (P = 0.03). CONCLUSIONS: State legislation requiring schools to have an AED, if financially feasible, was associated with a significant increase in AED presence among New Haven County high schools. Small high schools and those with a higher percentage of students with disabilities remain less likely to have an AED despite legislation.

COVID-19: Transatlantic Declines in Pediatric Emergency Admissions.

INTRODUCTION: This cross-sectional study looked at the impact of the SARS-CoV-2/COVID-19 pandemic on pediatric emergency department (PED) attendances and admissions (as a proxy for severity of illness) in the United States and United Kingdom. METHODS: Data were extracted for children and adolescents, younger than 16 years, attending Royal Manchester Children's Hospital (RMCH, United Kingdom), and Yale New Haven Children's Hospital (YNHCH, United States). Attendances for weeks 1 to 20 of 2020 and 2019 were compared, and likelihood of admission was assessed via calculation of odds ratios, using week 13 (lockdown) as a cutoff. RESULTS: Attendance numbers for each PED decreased in 2020 compared with 2019 (RMCH, 29.2%; YNHCH, 24.8%). Odds of admission were significantly higher after lockdown than in 2019-RMCH (odds ratio, 1.26; 95% confidence interval, 1.08-1.46) and YNHCH (odds ratio, 1.60; 95% confidence interval, 1.31-1.98). CONCLUSIONS: Although the absolute numbers of children and adolescents attending the PED and being admitted decreased after lockdown, the acuity of illness of those attending appears to be higher.

GPS Devices in a Simulated Mass Casualty Event.

OBJECTIVE: The aim of this study was to assess the staff perception of a global positioning system (GPS) as a patient tracking tool at an emergency department (ED) receiving patients from a simulated mass casualty event. METHODS: During a regional airport disaster drill a plane crash with 46 pediatric patients was simulated. Personnel from airport fire, municipal fire, law enforcement, emergency medical services, and emergency medicine departments were present. Twenty of the 46 patient actors required transport for medical evaluation, and we affixed GPS devices to 12 of these actors. At the hospital, ED staff including attending physicians, fellows and nurses working in the ED during the time of the drill accessed a map through an application that provided real-time geolocation of these devices. The primary outcome was staff reception of the GPS device as assessed via Likert scale survey after the event. The secondary outcomes were free text feedback from staff and event debriefing observations. RESULTS: Queried registered nurses, attending physicians, and pediatric emergency medicine fellows perceived the GPS device as an advantage for patient care during a disaster. The GPS device allowed multiple-screen real-time tracking and improved situational awareness in cases with and without EMS radio communication prior to arrival at the hospital. CONCLUSION: ED staff reported that the use of GPS trackers in a disaster improved real-time tracking and could potentially improve patient management during a mass casualty event.

Correlation Between Paramedic Disaster Triage Accuracy in Screen-Based Simulations and Immersive Simulations.

Background: Disaster triage is an infrequent, high-stakes skill set used by emergency medical services (EMS) personnel. Screen-based simulation (SBS) provides easy access to asynchronous disaster triage education. However, it is unclear if the performance during a SBS correlates with immersive simulation performance. Methods: This was a nested cohort study within a randomized controlled trial (RCT). The RCT compared triage accuracy of paramedics and emergency medical technicians (EMTs) who completed an immersive simulation of a school shooting, interacted with an SBS for 13 weeks, and then completed the immersive simulation again. The participants were divided into two groups: those exposed vs. those not exposed to 60 Seconds to Survival© (60S), a disaster triage SBS. The aim of the study was to measure the correlation between SBS triage accuracy and immersive simulation triage accuracy. Improvements in triage accuracy were compared among participants in the nested study before and after interacting with 60S, and with improvements in triage accuracy in a previous study in which immersive simulations were used as an educational intervention. Results: Thirty-nine participants completed the SBS; 26 (67%) completed at least three game plays and were included in the evaluation of outcomes of interest. The mean number of plays was 8.5 (SD =7.4). Subjects correctly triaged 12.4% more patients in the immersive simulation at study completion (73.1% before, 85.8% after, P = 0.004). There was no correlation between the amount of improvement in overall SBS triage accuracy, instances of overtriage (P = 0.101), instances of undertriage (P = 0.523), and improvement in the second immersive simulation. A comparison of the pooled data from a previous immersive simulation study with the nested cohort data showed similar improvement in triage accuracy (P = 0.079). Conclusions: SBS education was associated with a significant increase in triage accuracy in an immersive simulation, although triage accuracy demonstrated in the SBS did not correlate with the performance in the immersive simulation. This improvement in accuracy was similar to the improvement seen when immersive simulation was used as the educational intervention in a previous study.

Emergency Medical Responders and Adolescents With Autism Spectrum Disorder.

OBJECTIVES: Because of the high prevalence of Autism Spectrum Disorder (ASD) and wandering behavior, emergency medical responders (EMRs) will likely encounter children and adolescents with ASD. The objectives were to describe interactions between EMRs and children and adolescents with ASD, to evaluate EMRs' ability to recognize ASD in a simulated trauma setting, and to determine if EMRs' demographic characteristics affected their interactions with ASD youth. METHODS: A study of 75 videos of a simulated school bus crash was performed. The simulation included an adolescent with ASD portrayed by an actor. Videos were coded based on 5 domains: (1) reassurance attempts by the EMR, (2) quality of the EMR's interactions, (3) EMR's elicitation of information, (4) EMR's interactions with others, and (5) EMR's recognition of a disability. Two clinicians coded the videos independently, and consensus was reached for any areas of disagreement. RESULTS: Of 75 interactions, 27% provided reassurance to the adolescent with ASD, 1% elicited information, 11% asked bystanders for information or assistance, and 35% suggested a disability with 13% considering ASD. No differences across domains were found based on the EMR's sex. Emergency medical responders with greater than or equal to 5 years of experience were significantly more likely to elicit information than those with less than 5 years of experience, and paramedics had significantly higher total performance scores than paramedic students or those with EMT-Basic. CONCLUSIONS: Few EMRs in this study optimally interacted with adolescents with ASD or recognized a disability. These findings suggest a strong need for targeted educational interventions.

Pediatric Disaster Triage System Utilization Across the United States.

OBJECTIVES: The study goal was to determine which pediatric disaster triage (PDT) systems are used in US states/territories and whether there is standardization to their use. Secondary goals were to understand user satisfaction with each system, user preferences, and the nature and magnitude of incidents for which the systems are activated. METHODS: A survey was developed regarding PDT systems used in each state/territory, satisfaction with those used, preference for specific systems, and type and magnitude of incidents prompting system activation. The survey was distributed to emergency medical services for children leads in each state/territory. RESULTS: Eighty-six percent of states/territories responded. Eighty-eight percent of respondents used some formal PDT system, 50% of whom reported utilization of multiple systems. JumpSTART was most commonly used, most often in conjunction with other systems. Of formal systems, JumpSTART has been in use the longest. JumpSTART was also preferred by 71% of those stating a preference; it tied with Smart for median satisfaction level. Although types of incidents prompting system activation was similar across responding states/territories, number of patients prompting activation varied from 1 to 3 to greater than 20, median range of 4 to 7. CONCLUSIONS: Most states/territories use some formal PDT system; few have 1 standardized approach. JumpSTART is predominantly used and is preferred by most respondents. With all systems, there is marked variation in number of patients prompting activation although the reported nature of incidents prompting activation is similar.

Development of a Pediatric Mass Casualty Triage Algorithm Validation Tool.

BACKGROUND: Rapid, accurate evaluation and sorting of victims in a mass casualty incident (MCI) is crucial, as over-triage of victims may overwhelm a trauma system and under-triage may lead to an increase in morbidity and mortality. At this time, there is no validation tool specifically developed for the pediatric population to test an MCI algorithm's inherent capabilities to correctly triage children. OBJECTIVE: To develop a set of criteria for outcomes and interventions to be used as a validation tool for testing an MCI algorithm's ability to correctly triage patients from a cohort of pediatric trauma patients. METHODS: Expert opinion and literature review was used to formulate an initial Criteria Outcomes Tool (COT) that retrospectively categorizes pediatric (≤14 years of age) MCI victims based on resource utilization and clinical outcomes using the classic Red to Black MCI triage designations: Red - cardiopulmonary or mental status compromise needing intervention, Yellow - stable cardiopulmonary status but may require life or limb therapy, Green - minimally injured, and Black - deceased or likely to die given the circumstances. Using an anatomic approach, a list of criteria were defined and a modified-Delphi approach was used to create a summative COT that was reviewed by the American Academy of Pediatrics Disaster Preparedness Advisory Council. The resulting COT was independently applied to a weighted retrospective cohort of 25 pediatric victims from a single Level I trauma center by two reviewers to determine reproducibility. RESULTS: We created a Criteria Outcomes Tool (COT) with 47 outcomes and interventions to validate an MCI algorithm's triage designation. When the COT was applied to a cohort of 25 weighted pediatric charts, we identified the following resource utilization and outcome based triage designations: six Red, six Yellow, six Green, and seven Black triage outcomes. The 100% agreement was obtained between the two reviewers in each of the four categories. CONCLUSIONS: We designed an outcomes and resource utilization tool, the COT, to evaluate the ability of an MCI algorithm to correctly triage pediatric patients. Our tool has good reproducibility on initial study. KEY WORDS: pediatric; disaster; validation tools; triage algorithms; emergency.

On Shaky Ground: Learner Response and Confidence After Tabletop Earthquake Simulation.

OBJECTIVE: The aim of this study was to evaluate residents' confidence and attitudes related to management of earthquake victims during a tabletop simulation and 6 months after the intervention. METHODS: Pediatric residents from 4 training programs were recruited via e-mail. The tabletop simulation involved 3 pediatric patients (crush injury, head injury, and a nonverbal patient with minor injuries). A facilitated debriefing took place after the simulation. The same simulation was repeated 6 months later. A survey was administered before the simulation, immediately after, and after the 6-month repeat simulation to determine participants' self-rated confidence and willingness to respond in the event of a disaster. A 5-point Likert scale that ranged through novice, advanced beginner, competent, proficient, and expert was used. RESULTS: Ninety-nine participants completed the survey before the initial simulation session. Fifty-one residents completed the immediate postsurvey, and 75 completed the 6-month postsurvey. There was a statistically significant improvement in self-rated confidence identifying and managing victims of earthquake disasters after participating in the simulation, with 3% rating themselves as competent on the presurvey and 33% rating themselves as competent on the postsurvey (P < 0.05). There was a nonstatistically significant improvement in confidence treating suspected traumatic head injury as well as willingness to deploy to both domestic and international disasters. CONCLUSIONS: Tabletop simulation can improve resident comfort level with rare events, such as caring for children in the aftermath of an earthquake. Tabletop can also be easily integrated into resident curriculum and may be an effective way to provide disaster medical response training for trainees.

A better START for low-acuity victims: data-driven refinement of mass casualty triage.

OBJECTIVE: Methods currently used to triage patients from mass casualty events have a sparse evidence basis. The objective of this project was to assess gaps of the widely used Simple Triage and Rapid Transport (START) algorithm using a large database when it is used to triage low-acuity patients. Subsequently, we developed and tested evidenced-based improvements to START. METHODS: Using the National Trauma Database (NTDB), a large set of trauma victims were assigned START triage levels, which were then compared to recorded patient mortality outcomes using area under the receiver-operator curve (AUC). Subjects assigned to the "Minor/Green" level who nevertheless died prior to hospital discharge were considered mistriaged. Recursive partitioning identified factors associated with of these mistriaged patients. These factors were then used to develop candidate START models of improved triage, whose overall performance was then re-evaluated using data from the NTDB. This process of evaluating performance, identifying errors, and further adjusting candidate models was repeated iteratively. RESULTS: The study included 322,162 subjects assigned to "Minor/Green" of which 2,046 died before hospital discharge. Age was the primary predictor of under-triage by START. Candidate models which re-assigned patients from the "Minor/Green" triage level to the "Delayed/Yellow" triage level based on age (either for patients >60 or >75), reduced mortality in the "Minor/Green" group from 0.6% to 0.1% and 0.3%, respectively. These candidate START models also showed net improvement in the AUC for predicting mortality overall and in select subgroups. CONCLUSION: In this research model using trauma registry data, most START under-triage errors occurred in elderly patients. Overall START accuracy was improved by placing elderly but otherwise minimally injured-mass casualty victims into a higher risk triage level. Alternatively, such patients would be candidates for closer monitoring at the scene or expedited transport ahead of other, younger "Minor/Green" victims.

Barriers to pediatric disaster triage: a qualitative investigation.

BACKGROUND: In disasters, paramedics often triage victims, including children. Little is known about obstacles paramedics face when performing pediatric disaster triage. OBJECTIVE: To determine obstacles to pediatric disaster triage performance for paramedics enrolled in a simulation-based disaster curriculum. DESIGN: We conducted a qualitative evaluation of paramedics' self-reported obstacles to pediatric disaster triage performance. The paramedics were enrolled in a pediatric disaster triage curriculum at one of three study sites. An individually administered, semi-structured debriefing was created iteratively, and used after a 10-victim, multiple-family house fire simulation. The debriefings were audio-recorded, and transcribed. Two investigators independently analyzed the transcripts. Using grounded theory strategy, the data were analyzed via 1) immersion and coding of data, 2) clustering of codes to generate themes, and 3) theme-based generation of hypotheses. While analyzing the data, we employed peer debriefing to determine emerging codes, groups, and thematic saturation. Systematically applied data trustworthiness strategies included triangulation and member checking. RESULTS: A total of 34 participants were debriefed, with prehospital care experience ranging from 1 to 25 years of experience. We identified several barriers to pediatric disaster triage: 1) lack of familiarity with children and their physiology, 2) challenges with triaging children with special health-care needs, 3) emotional reactions to triage situations, including a mother holding an injured/dead child, and 4) training limitations, including poor simulation fidelity. CONCLUSION: Paramedics report particular difficulty triaging multiple child disaster victims due to emotional obstacles, unfamiliarity with pediatric physiology, and struggles with triage rationale and efficiency.

Do you see what I see? Insights from using google glass for disaster telemedicine triage.

INTRODUCTION: Disasters are high-stakes, low-frequency events. Telemedicine may offer a useful adjunct for paramedics performing disaster triage. The objective of this study was to determine the feasibility of telemedicine in disaster triage, and to determine whether telemedicine has an effect on the accuracy of triage or the time needed to perform triage. METHODS: This is a feasibility study in which an intervention team of two paramedics used the mobile device Google Glass (Google Inc; Mountain View, California USA) to communicate with an off-site physician disaster expert. The paramedic team triaged simulated disaster victims at the triennial drill of a commercial airport. The simulated victims had preassigned expected triage levels. The physician had an audio-video interface with the paramedic team and was able to observe the victims remotely. A control team of two paramedics performed disaster triage in the usual fashion. Both teams used the SMART Triage System (TSG Associates LLP; Halifax, England), which assigns patients into Red, Yellow, Green, and Black triage categories. The paramedics were video recorded, and their time required to triage was logged. It was determined whether the intervention team and the control team varied regarding accuracy of triage. Finally, the amount of time the intervention team needed to triage patients when telemedicine was used was compared to when that team did not use telemedicine. RESULTS: The two teams triaged the same 20 patients. There was no significant difference between the two groups in overall triage accuracy (85.7% for the intervention group vs 75.9% for the control group; P = .39). Two patients were triaged with telemedicine. For the intervention group, there was a significant difference in time to triage patients with telemedicine versus those without telemedicine (35.5 seconds; 95% CI, 72.5-143.5 vs 18.5 seconds; 95% CI, 13.4-23.6; P = .041). CONCLUSION: There was no increase in triage accuracy when paramedics evaluating disaster victims used telemedicine, and telemedicine required more time than conventional triage. There are a number of obstacles to available technology that, if overcome, might improve the utility of telemedicine in disaster response.

Creation and Delphi-method refinement of pediatric disaster triage simulations.

OBJECTIVE: There is a need for rigorously designed pediatric disaster triage (PDT) training simulations for paramedics. First, we sought to design three multiple patient incidents for EMS provider training simulations. Our second objective was to determine the appropriate interventions and triage level for each victim in each of the simulations and develop evaluation instruments for each simulation. The final objective was to ensure that each simulation and evaluation tool was free of bias toward any specific PDT strategy. METHODS: We created mixed-methods disaster simulation scenarios with pediatric victims: a school shooting, a school bus crash, and a multiple-victim house fire. Standardized patients, high-fidelity manikins, and low-fidelity manikins were used to portray the victims. Each simulation had similar acuity of injuries and 10 victims. Examples include children with special health-care needs, gunshot wounds, and smoke inhalation. Checklist-based evaluation tools and behaviorally anchored global assessments of function were created for each simulation. Eight physicians and paramedics from areas with differing PDT strategies were recruited as Subject Matter Experts (SMEs) for a modified Delphi iterative critique of the simulations and evaluation tools. The modified Delphi was managed with an online survey tool. The SMEs provided an expected triage category for each patient. The target for modified Delphi consensus was ≥85%. Using Likert scales and free text, the SMEs assessed the validity of the simulations, including instances of bias toward a specific PDT strategy, clarity of learning objectives, and the correlation of the evaluation tools to the learning objectives and scenarios. RESULTS: After two rounds of the modified Delphi, consensus for expected triage level was >85% for 28 of 30 victims, with the remaining two achieving >85% consensus after three Delphi iterations. To achieve consensus, we amended 11 instances of bias toward a specific PDT strategy and corrected 10 instances of noncorrelation between evaluations and simulation. CONCLUSIONS: The modified Delphi process, used to derive novel PDT simulation and evaluation tools, yielded a high degree of consensus among the SMEs, and eliminated biases toward specific PDT strategies in the evaluations. The simulations and evaluation tools may now be tested for reliability and validity as part of a prehospital PDT curriculum.

Head-to-head comparison of disaster triage methods in pediatric, adult, and geriatric patients.

STUDY OBJECTIVE: A variety of methods have been proposed and used in disaster triage situations, but there is little more than expert opinion to support most of them. Anecdotal disaster experiences often report mediocre real-world triage accuracy. The study objective was to determine the accuracy of several disaster triage methods when predicting clinically important outcomes in a large cohort of trauma victims. METHODS: Pediatric, adult, and geriatric trauma victims from the National Trauma Data Bank were assigned triage levels, using each of 6 disaster triage methods: simple triage and rapid treatment (START), Fire Department of New York (FDNY), CareFlight, Glasgow Coma Scale (GCS), Sacco Score, and Unadjusted Sacco Score. Methods for approximating triage systems were vetted by subject matter experts. Triage assignments were compared against patient mortality at hospital discharge with area under the receiver operator curve. Secondary outcomes included death in the emergency department, use of a ventilator, and lengths of stay. Subgroup analysis assessed triage accuracy in patients by age, trauma type, and sex. RESULTS: In this study, 530,695 records were included. The Sacco Score predicted mortality most accurately, with area under the receiver operator curve of 0.883 (95% confidence interval 0.880 to 0.885), and performed well in most subgroups. FDNY was more accurate than START for adults but less accurate for children. CareFlight was best for burn victims, with area under the receiver operator curve of 0.87 (95% confidence interval 0.85 to 0.89) but mistriaged more salvageable trauma patients to "dead/black" (41% survived) than did other disaster triage methods (≈10% survived). CONCLUSION: Among 6 disaster triage methods compared against actual outcomes in trauma registry patients, the Sacco Score predicted mortality most accurately. This analysis highlighted comparative strengths and weakness of START, FDNY, CareFlight, and Sacco, suggesting areas in which each might be improved. The GCS predicted outcomes similarly to dedicated disaster triage strategies.

Predictive value of initial Glasgow coma scale score in pediatric trauma patients.

OBJECTIVE: The objective of this study was to determine the predictive value of the Glasgow coma scale (GCS) and the Glasgow motor component (GMC) for overall mortality, death on arrival, and major injury and the relationship between GCS and length of stay (LOS) in the emergency department (ED) and hospital. METHODS: Records from the American College of Surgeons National Trauma Data Base from 2007 to 2009 were extracted. Patients 0 to 18 years old transported from a trauma scene with complete initial scene data were included. Statistical analysis, including construction of receiver-operator curves, determined the correlation between GCS, GMC, and the clinical outcomes of interest. RESULTS: There were 104,035 records with complete data for analysis, including 3946 deaths. Mean patient age was 12.6 (SD, 5.5) years. Glasgow coma scale was predictive of overall mortality, with area under the receiver-operator curve (AUC) of 0.946 (95% confidence interval [CI], 0.941-0.951); death on arrival, with AUC of 0.958 (95% CI, 0.953-0.963); and risk of major injury, with AUC of 0.720 (0.715-0.724). Lower GCS scores were associated with shorter ED LOS and longer hospital stays (P <0.001, analysis of variance) except GCS 3, associated with shorter hospitalizations. For predicting overall mortality, the AUC for GMC was 0.940 (95% CI, 0.935-0.945), and for predicting major injury, the AUC was 0.681 (95% CI, 0.677-0.686). CONCLUSIONS: For pediatric trauma victims, the GCS is predictive of mortality and injury outcomes, as well as both ED and hospital LOS, and has excellent prognostic accuracy. The GMC has predictive value for injury and mortality that is nearly equivalent to the full GCS.

Going viral: adapting to pediatric surge during the H1N1 pandemic.

OBJECTIVES: The objective of this study was to assess hospital and emergency department (ED) pediatric surge strategies utilized during the 2009 H1N1 influenza pandemic as well as compliance with national guidelines. METHODS: Electronic survey was sent to a convenience sample of emergency physicians and nurses from US EDs with a pediatric volume of more than 10,000 annually. Survey questions assessed the participant's hospital baseline pandemic and surge preparedness, as well as strategies for ED surge and compliance with Centers for Disease Control and Prevention (CDC) guidelines for health care personal protection, patient testing, and treatment. RESULTS: The response rate was 54% (53/99). Preexisting pandemic influenza plans were absent in 44% of hospitals; however, 91% developed an influenza plan as a result of the pandemic. Twenty-four percent reported having a preexisting ED pandemic staffing model, and 36% had a preexisting alternate care site plan. Creation and/or modifications of existing plans for ED pandemic staffing (82%) and alternate care site plan (68%) were reported. Seventy-nine percent of institutions initially followed CDC guidelines for personal protection (use of N95 masks), of which 82% later revised their practices. Complete compliance with CDC guidelines was 60% for patient testing and 68% for patient treatment. CONCLUSIONS: Before the H1N1 pandemic, greater than 40% of the hospitals in our study did not have an influenza pandemic preparedness plan. Many had to modify their existing plans during the surge. Not all institutions fully complied with CDC guidelines. Data from this multicenter survey should assist clinical leaders to create more robust surge plans for children.
