Scenario-Based e-Simulation Design for Global Health Education: Theoretical Foundation and Practical Recommendations.

Electronic simulation (e-simulation)-particularly scenario-based e-simulation (SBES)-is an increasingly used, promising educational strategy for global health education that can address gaps in training access, effectiveness, and cost. However, there is little guidance for educators on how to develop an SBES, and guidance is lacking outside the clinical context. Moreover, literature on medical education rarely uses the theoretical basis for e-simulation design and development, including for SBES. Hence, we aim to differentiate and describe the concept, design elements, and theoretical basis of SBES with examples from different topics in global health. In addition to enhancing the understanding of the potential of SBES for global health education, this manuscript also provides practical recommendations for global health educators in designing and developing SBESs based on the existing literature and authors' experiences. Overall, this manuscript will be useful for global health educators as well as other medical educators seeking to develop an SBES for similar skill sets.

Development of an Anticipatory Triage-Ranking Algorithm Using Dynamic Simulation of the Expected Time Course of Patients With Trauma: Modeling and Simulation Study.

BACKGROUND: In cases of terrorism, disasters, or mass casualty incidents, far-reaching life-and-death decisions about prioritizing patients are currently made using triage algorithms that focus solely on the patient's current health status rather than their prognosis, thus leaving a fatal gap of patients who are under- or overtriaged. OBJECTIVE: The aim of this proof-of-concept study is to demonstrate a novel approach for triage that no longer classifies patients into triage categories but ranks their urgency according to the anticipated survival time without intervention. Using this approach, we aim to improve the prioritization of casualties by respecting individual injury patterns and vital signs, survival likelihoods, and the availability of rescue resources. METHODS: We designed a mathematical model that allows dynamic simulation of the time course of a patient's vital parameters, depending on individual baseline vital signs and injury severity. The 2 variables were integrated using the well-established Revised Trauma Score (RTS) and the New Injury Severity Score (NISS). An artificial patient database of unique patients with trauma (N=82,277) was then generated and used for analysis of the time course modeling and triage classification. Comparative performance analysis of different triage algorithms was performed. In addition, we applied a sophisticated, state-of-the-art clustering method using the Gower distance to visualize patient cohorts at risk for mistriage. RESULTS: The proposed triage algorithm realistically modeled the time course of a patient's life, depending on injury severity and current vital parameters. Different casualties were ranked by their anticipated time course, reflecting their priority for treatment. Regarding the identification of patients at risk for mistriage, the model outperformed the Simple Triage And Rapid Treatment's triage algorithm but also exclusive stratification by the RTS or the NISS. Multidimensional analysis separated patients with similar patterns of injuries and vital parameters into clusters with different triage classifications. In this large-scale analysis, our algorithm confirmed the previously mentioned conclusions during simulation and descriptive analysis and underlined the significance of this novel approach to triage. CONCLUSIONS: The findings of this study suggest the feasibility and relevance of our model, which is unique in terms of its ranking system, prognosis outline, and time course anticipation. The proposed triage-ranking algorithm could offer an innovative triage method with a wide range of applications in prehospital, disaster, and emergency medicine, as well as simulation and research.

The Incremental Hospitalization Cost of Significant Transport-Related Traumatic Brain Injury.

AIM: This study aims to determine the incremental cost of acute hospitalization for traumatic brain injury (TBI) compared with matched controls. A second purpose is to identify the factors contributing to this hospital costs. METHODOLOGY: Analyses were performed on administrative data for injured patients, hospitalized in Belgium between 2009 and 2011 following a road traffic accident. Cases were matched to a control with similar injuries but without TBI. The incremental hospitalization cost of TBI and the factors contributing to the hospital costs were determined using multivariable regression modeling with gamma distribution and log link. RESULTS: A descriptive comparison of cases and controls shows clear differences in healthcare utilization and costs. The presence of a TBI increases the cost by a factor between 1.66 (95% confidence interval: 1.52-1.82) and 2.08 (95% confidence interval: 1.72-2.51). Regarding healthcare utilization, the most important determinants of hospital costs are surgical complexity, use of magnetic resonance imaging, intensive care unit admission, and mechanical ventilation. DISCUSSION: To our knowledge, this is the first matched-control study calculating the incremental hospitalization cost of TBI. The insights provided by this study are relevant in the context of prospective payments and can be an incentive for investments in prevention policies and extramural care.

The incremental cost of traumatic brain injury during the first year after a road traffic accident.

This study aims to determine the incremental cost of TBI during the first year after a traffic accident, compared to other patients with similar non-TBI injuries. Secondly, identification of factors associated with medical costs of TBI is pursued. Analyses were performed on administrative data for traffic victims hospitalised in Belgium between 2009 and 2011. Medical costs attributable to the accident are estimated over one year post-injury. Cases with TBI were matched to controls with similar non-TBI injuries to determine the incremental cost of TBI. Both aims of this research were assessed using regression analysis. The incremental cost of TBI is estimated to range between € 10 042 (95%CI [€8198; €11 887]) and €21 715 (95%CI [€13 5889; €29 540]). Age, problems with self-reliance, survival status, the occurrence of acute events and severity of TBI are significant predictors of medical costs. As to healthcare utilisation, MRI usage, inpatient rehabilitation facilities, nursing homes and readmissions to acute hospital stand out as having most influence on costs. This study reveals a considerable incremental cost of TBI. Policy-making bodies should be made aware of this phenomenon and a diversified policy should be considered when financing programs are discussed.

Development and Pilot Testing of 24/7 In-Ambulance Telemedicine for Acute Stroke: Prehospital Stroke Study at the Universitair Ziekenhuis Brussel-Project.

BACKGROUND: In-ambulance telemedicine is a recently developed and a promising approach to improve emergency care. We implemented the first ever 24/7 in-ambulance telemedicine service for acute stroke. We report on our experiences with the development and pilot testing of the Prehospital Stroke Study at the Universitair Ziekenhuis Brussel (PreSSUB) to facilitate a wider spread of the knowledge regarding this technique. METHODS: Successful execution of the project involved the development and validation of a novel stroke scale, design and creation of specific hardware and software solutions, execution of field tests for mobile internet connectivity, design of new care processes and information flows, recurrent training of all professional caregivers involved in acute stroke management, extensive testing on healthy volunteers, organisation of a 24/7 teleconsultation service by trained stroke experts and 24/7 technical support, and resolution of several legal issues. RESULTS: In all, it took 41 months of research and development to confirm the safety, technical feasibility, reliability, and user acceptance of the PreSSUB approach. Stroke-specific key information can be collected safely and reliably before and during ambulance transportation and can adequately be communicated with the inhospital team awaiting the patient. CONCLUSION: This paper portrays the key steps required and the lessons learned for successful implementation of a 24/7 expert telemedicine service supporting patients with acute stroke during ambulance transportation to the hospital.

SIMEDIS: a Discrete-Event Simulation Model for Testing Responses to Mass Casualty Incidents.

It is recognized that the study of the disaster medical response (DMR) is a relatively new field. To date, there is no evidence-based literature that clearly defines the best medical response principles, concepts, structures and processes in a disaster setting. Much of what is known about the DMR results from descriptive studies and expert opinion. No experimental studies regarding the effects of DMR interventions on the health outcomes of disaster survivors have been carried out. Traditional analytic methods cannot fully capture the flow of disaster victims through a complex disaster medical response system (DMRS). Computer modelling and simulation enable to study and test operational assumptions in a virtual but controlled experimental environment. The SIMEDIS (Simulation for the assessment and optimization of medical disaster management) simulation model consists of 3 interacting components: the victim creation model, the victim monitoring model where the health state of each victim is monitored and adapted to the evolving clinical conditions of the victims, and the medical response model, where the victims interact with the environment and the resources at the disposal of the healthcare responders. Since the main aim of the DMR is to minimize as much as possible the mortality and morbidity of the survivors, we designed a victim-centred model in which the casualties pass through the different components and processes of a DMRS. The specificity of the SIMEDIS simulation model is the fact that the victim entities evolve in parallel through both the victim monitoring model and the medical response model. The interaction between both models is ensured through a time or medical intervention trigger. At each service point, a triage is performed together with a decision on the disposition of the victims regarding treatment and/or evacuation based on a priority code assigned to the victim and on the availability of resources at the service point. The aim of the case study is to implement the SIMEDIS model to the DMRS of an international airport and to test the medical response plan to an airplane crash simulation at the airport. In order to identify good response options, the model then was used to study the effect of a number of interventional factors on the performance of the DMRS. Our study reflects the potential of SIMEDIS to model complex systems, to test different aspects of DMR, and to be used as a tool in experimental research that might make a substantial contribution to provide the evidence base for the effectiveness and efficiency of disaster medical management.

Prehospital stroke care: limitations of current interventions and focus on new developments.

BACKGROUND: The global burden of stroke is immense, both in medical and economic terms. With the aging population and the ongoing industrialization of the third world, stroke prevalence is expected to increase and will have a major effect on national health expenditures. Currently, the medical treatment for acute ischemic stroke is limited to intravenous recombinant tissue plasminogen activator (IV r-tPA), but its time dependency leads to low utilization rates in routine clinical practice. Prehospital delay contributes significantly to delayed or missed treatment opportunities in acute stroke. State-of-the-art acute stroke care, starting in the prehospital phase, could thereby reduce the disease burden and its enormous financial costs. SUMMARY: The first part of this review focuses on current education measures for the general public, the emergency medical services (EMS) dispatchers and paramedics. Although much has been expected of these measures to improve stroke care, no major effects on prehospital delay or missed treatment opportunities have been demonstrated over the years. Most interventional studies showed little or no effect on the onset-to-door time, IV r-tPA utilization rates or outcome, except for prenotification of the receiving hospital by the EMS. No data are currently available on the cost-effectiveness of these commonly used measures. In the second part, we discuss new developments for the improvement of prehospital stroke diagnosis and treatment which could open new perspectives in the nearby future. These include the implementation of prehospital telestroke and the deployment of mobile stroke units. These approaches may improve patient care and could serve as a platform for prehospital clinical trials. Other opportunities include the implementation of noninvasive diagnostics (like transcranial ultrasound and blood-borne biomarkers) and the reevaluation of neuroprotective strategies in the prehospital phase. Key Messages: Timely initiation of treatment can effectively reduce the medical and economic burden of stroke and should begin with optimal prehospital stroke care. For this, prehospital telemedicine is a particularly attractive approach because it is a scalable solution that has the potential to rapidly optimize acute stroke care at limited cost.

Acute gastric dilatation causing acute limb ischemia in an anorexia nervosa patient.

BACKGROUND: Acute gastric dilatation is a rare but severe complication of anorexia nervosa. Gastric dilatation causing abdominal compartment syndrome with lower-limb ischemia is even less common. This case report illustrates the importance of a holistic clinical approach of every patient presenting to the emergency department (ED), even when the reason for admittance is organ specific. CASE REPORT: We report the case of a young female patient presenting to the ED with a painful white left leg. Clinical examination revealed acute lower-limb ischemia, abdominal distention, and shock. Diagnostic work-up, including an abdominal computed tomography scan, showed compression of the aorta, inferior vena cava, and both iliac arteries, as well as hypoperfusion of the right kidney and left liver lobe, all due to compression by a massive gastric dilatation. Gastroscopy revealed a massively dilated stomach containing > 6 L of fluid and gastric wall ischemia. After decompression, the circulation to the lower limbs recovered immediately. The day after admission the patient developed an acute abdomen leading to a semi-urgent laparoscopy during which a sleeve gastrectomy was performed for the treatment of partial gastric necrosis. Clinical evolution afterward was favorable and the patient recovered completely. CONCLUSIONS: This case report underscores the importance of a thorough clinical examination in every patient admitted to the ED. Early diagnosis and treatment are mandatory in preventing fatal complications.

The Use of the Health Belief Model in the Context of Heatwaves Research: A Rapid Review.

As heatwaves increase and intensify worldwide, so has the research aimed at outlining strategies to protect individuals from their impact. Interventions that promote adaptive measures to heatwaves are encouraged, but evidence on how to develop such interventions is still scarce. Although the Health Belief Model is one of the leading frameworks guiding behavioral change interventions, the evidence of its use in heatwave research is limited. This rapid review aims to identify and describe the main themes and key findings in the literature regarding the use of the Health Belief Model in heatwaves research. It also highlights important research gaps and future research priorities. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, 10 articles were included, with a geographic distribution as follows: United States (n = 1), Australia (n = 1), Pakistan (n = 1), and China (n = 1), as well as Malaysia (n = 2), Germany (n = 1), and Austria (n = 1). Results showed a lack of research using the Health Belief Model to study heatwaves induced by climate change. Half of the studies assessed heatwave risk perception, with the 2 most frequently used constructs being Perceived Susceptibility and Perceived Severity. The Self-efficacy construct was instead used less often. Most of the research was conducted in urban communities. This review underscores the need for further research using the Health Belief Model.

Assessing primary healthcare disaster preparedness: a study in Northern Italy.

AIM: The aim of this paper is to outline the steps taken to develop an operational checklist to assess primary healthcare (PHC) all-hazards disaster preparedness. It then describes a study testing the applicability of the checklist. BACKGROUND: A PHC approach is an essential foundation for health emergency and disaster risk management (H-EDRM) because it can prevent and mitigate risks prior to disasters and support an effective response and recovery, thereby contributing to communities' and countries' resilience across the continuum of the disaster cycle. This approach is in line with the H-EDRM framework, published by the World Health Organization (WHO) in 2019, which emphasizes a whole-of-health system approach in disaster management and highlights the importance of integrating PHC into countries' H-EDRM. Nevertheless, literature focusing on how to practically integrate PHC into disaster management, both at the facility and at the policy level, is in its infancy. As of yet, there is no standardized, validated way to assess the specific characteristics that render PHC prepared for disasters nor a method to evaluate its role in H-EDRM. METHODS: The checklist was developed through an iterative process that leveraged academic literature and expert consultations at different stages of the elaboration process. It was then used to assess primary care facilities in a province in Italy. FINDINGS: The checklist offers a practical instrument for assessing and enhancing PHC disaster preparedness and for improving planning, coordination, and funding allocation. The study identified three critical areas for improvement in the province's PHC disaster preparedness. First, primary care teams should be more interdisciplinary. Second, primary care services should be more thoroughly integrated into the broader health system. Third, there is a notable lack of awareness of H-EDRM principles among PHC professionals. In the future, the checklist can be elaborated into a weighted tool to be more broadly applicable.

FFRct use for acute chest pain triage in the emergency department: a cost-effectiveness analysis.

AIMS: To model and assess the cost-effectiveness of CT-based fractional flow reserve (FFRct) for a population of low to intermediate risk patients for coronary artery disease (CAD) presenting to the emergency department (ED) with acute chest pain. METHODS AND RESULTS: Using a decision tree model with a 1 year time horizon and from a health care perspective, two diagnostic pathways using FFRct are compared to current clinical routine combining coronary computed tomography angiography (CCTA) with an exercise test. Model data are drawn from the literature and nationally reported data. Outcomes are assessed as the number of avoided invasive coronary angiographies (ICAs) showing no obstructive CAD and quality of life (QoL) in a theoretical cohort of 1000 patients. Sensitivity analyses are performed to test the robustness of the results. Determining FFRct when CCTA is inconclusive is a cost-effective and dominant strategy with a potential saving of 198€/patient, 154 avoided unnecessary ICA showing no obstructive CAD (uICA)/1000 patients and an average improvement in QoL of 0.008 QALY/patient. With an additional 574€/patient, 8 avoided uICA/1000 patients and an improvement in QoL of 0.001 QALY/patient, a strategy where FFRct is always performed is cost-effective only when considering high cost-effectiveness thresholds. CONCLUSIONS: For patients presenting to the ED with acute chest pain and a low to intermediate pre-test probability of CAD, a diagnostic strategy where FFRct is determined after an inconclusive CCTA is cost-effective. Clinical trials investigating both sensitivity and specificity of FFRct, as well as QoL associated with the use of this technology in this setting are warranted.

A retrospective comparison of mechanical cardio-pulmonary ventilation and manual bag valve ventilation in non-traumatic out-of-hospital cardiac arrests: A study from the Belgian cardiac arrest registry.

BACKGROUND: The optimal ventilation modalities to manage out-of-hospital cardiac arrest (OHCA) remain debated. A specific pressure mode called cardio-pulmonary ventilation (CPV) may be used instead of manual bag ventilation (MBV). We sought to analyse the association between mechanical CPV and return of spontaneous circulation (ROSC) in non-traumatic OHCA. METHODS: MBV and CPV were retrospectively identified in patients with non-traumatic OHCA from the Belgian Cardiac Arrest Registry. We used a two-level mixed-effects multivariable logistic regression analysis to determine the association between the ventilation modalities and outcomes. The primary and secondary study criteria were ROSC and survival with a Cerebral Performance Category (CPC) score of 1 or 2 at 30 days. Age, sex, initial rhythm, no-flow duration, low-flow duration, OHCA location, use of a mechanical chest compression device and Rankin status before arrest were used as covariables. RESULTS: Between January 2017 and December 2021, 2566 patients with OHCA who fulfilled the inclusion criteria were included. 298 (11.6%) patients were mechanically ventilated with CPV whereas 2268 were manually ventilated. The use of CPV was associated with greater probability of ROSC both in the unadjusted (odds ratio: 1.28, 95% confidence interval [CI]: 1.01-1.63; p = 0.043) and adjusted analyses (adjusted odds ratio [aOR]: 2.16, 95%CI 1.37-3.41; p = 0.001) but not with a lower CPC score (aOR: 1.44, 95%CI 0.72-2.89; p = 0.31). CONCLUSIONS: Compared with MBV, CPV was associated with an increased risk of ROSC but not with improved an CPC score in patients with OHCA. Prospective randomised trials are needed to challenge these results.

Prehospital unassisted assessment of stroke severity using telemedicine: a feasibility study.

BACKGROUND AND PURPOSE: We evaluated the feasibility and the reliability of remote stroke severity quantification in the prehospital setting using the Unassisted TeleStroke Scale (UTSS) via a telestroke ambulance system and a fourth-generation mobile network. METHODS: The technical feasibility and the reliability of the UTSS were studied in healthy volunteers mimicking 41 stroke syndromes during ambulance transportation. RESULTS: Except for 1 issue, high-quality telestroke assessment was feasible in all scenarios. The mean examination time for the UTSS was 3.1 minutes (SD, 0.4). The UTSS showed excellent intrarater and interrater variability (ρ=0.98 and 0.97; P<0.001), as well as excellent internal consistency and rater agreement. Adequate concurrent validity can be derived from the strong correlation between the UTSS and the National Institutes of Health Stroke Scale (ρ=0.90; P<0.001). CONCLUSIONS: Remote assessment of stroke severity in fast-moving ambulances using a system dedicated to prehospital telemedicine, 4G technology, and the UTSS is feasible and reliable.

The Impact of In-Event Health Services at Europe's Largest Electronic Dance Music Festival on Ems and Ed in the Host Community.

BACKGROUND: Electronic dance music festivals (EDMF) can cause a significant disruption in the standard operational capacity of emergency medical services (EMS) and hospitals. We determined whether or not the presence of in-event health services (IEHS) can reduce the impact of Europe's largest EDMF on the host community EMS and local emergency departments (EDs). METHODS: We conducted a pre-post analysis of the impact of Europe's largest EDMF in July 2019, in Boom, Belgium, on the host community EMS and local EDs. Statistical analysis included descriptive statistics, independent t-tests, and χ2 analysis. RESULTS: Of 400,000 attendees, 12,451 presented to IEHS. Most patients only required in-event first aid, but 120 patients had a potentially life-threatening condition. One hundred fifty-two patients needed to be transported by IEHS to nearby hospitals, resulting in a transport-to-hospital rate of 0.38/1000 attendees. Eighteen patients remained admitted to the hospital for >24 h; one died after arrival in the ED. IEHS limited the overall impact of the MGE on regular EMS and nearby hospitals. No predictive model proved optimal when proposing the optimal number and level of IEHS members. CONCLUSIONS: This study shows that IEHS at this event limited ambulance usage and mitigated the event's impact on regular emergency medical and health services.

Team Dynamics and Nontechnical Skills Perception During the Disaster Response in Mozambique in 2019: A Survey Study Among the Italian Emergency Medical Team.

OBJECTIVE: Team dynamics and nontechnical skills in general are crucial for emergency medical teams (EMT). No study has ever examined these important issues during a real mission in the field. This study aimed to better investigate team dynamics and nontechnical skills for EMTs; it tried to understand if a real mission, when the people are obliged to work together for the first time, without a prior specific training focused on teamwork, is enough or not to work as an effective team in the field. METHODS: The study is designed as a pre-test/post-test survey study, and it collected data from 51 people deployed to Mozambique in 2019. Three indexes (the self-efficacy (SE), the teamwork (TW), and the overall team's performance (TW12)) were calculated as the average value of the rating given by all the participants. Open text feedback was also collected. RESULTS: A positive trend was observed comparing the "post" data to the "pre" data, but results did not show a statistical significance, with the only exception of stratified analyses showing a P-value less than 0.05 for SE and TW12 for some categories. CONCLUSIONS: According to the study findings, humanitarian workers feel good but not at their best; training programs focused on team dynamics can be really useful to improve self-confidence of people leaving for a mission.

Prehospital Emergency Care in Low- and Middle-Income Countries: A Systematic Review.

BACKGROUND: An under-developed and fragmented prehospital Emergency Medical Services (EMS) system is a major obstacle to the timely care of emergency patients. Insufficient emphasis on prehospital emergency systems in low- and middle-income countries (LMICs) currently causes a substantial number of avoidable deaths from time-sensitive illnesses, highlighting a critical need for improved prehospital emergency care systems. Therefore, this systematic review aimed to assess the prehospital emergency care services across LMICs. METHODS: This systematic review used four electronic databases, namely: PubMed/MEDLINE, CINAHL, EMBASE, and SCOPUS, to search for published reports on prehospital emergency medical care in LMICs. Only peer-reviewed studies published in English language from January 1, 2010 through November 1, 2022 were included in the review. The Newcastle-Ottawa Scale (NOS) and Critical Appraisal Skills Programme (CASP) checklist were used to assess the methodological quality of the included studies. Further, the protocol of this systematic review has been registered on the International Prospective Register of Systematic Reviews (PROSPERO) database (Ref: CRD42022371936) and has been conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: Of the 4,909 identified studies, a total of 87 studies met the inclusion criteria and were therefore included in the review. Prehospital emergency care structure, transport care, prehospital times, health outcomes, quality of information exchange, and patient satisfaction were the most reported outcomes in the considered studies. CONCLUSIONS: The prehospital care system in LMICs is fragmented and uncoordinated, lacking trained medical personnel and first responders, inadequate basic materials, and substandard infrastructure.

Mental health and psychosocial support during physical rehabilitation in Eastern Democratic Republic of Congo: a retrospective cohort study.

PURPOSE: This study explores the relevance of integrating mental health and psychosocial support (MHPSS) into physical rehabilitation services in conflict settings. MATERIAL AND METHODS: Symptoms of psychological distress and daily functioning of 132 physical rehabilitation service users in Eastern Democratic Republic of Congo were assessed before and after MHPSS. Logistical regression models were used to identify factors associated with these symptoms. RESULTS: Prior to receiving MHPSS, "extreme" symptoms of depression were reported by 64% of the service users. Amputation predicted high levels of depression (aOR 5.12, p = 0.021), anxiety (aOR 7.09, p = 0.004) and stress (aOR 3.37, p = 0.035), while having witnessed violence predicted high symptoms of stress (aOR 3.65, p = 0.014). Lack of social support was associated with high symptoms of stress prior to MHPSS (aOR 3.17, p = 0.046) as well as a large reduction in symptoms of depression following MHPSS (aOR 3.91, p = 0.019). Most physical rehabilitation service users reported a reduction in symptoms of depression (100.00%), anxiety (98.03%) and stress (100.00%) along with improved functioning (81.13%) after MHPSS. CONCLUSION: MHPSS needs of physical rehabilitation service users in conflict settings stem from the combined impact of disability and exposure to violence. MHPSS care, particularly the mobilization of peer support, appears necessary and relevant.Implications for rehabilitationIn conflict settings, mental health and psychosocial support (MHPSS) needs of physical rehabilitation service users must address the combined impact of physical disability and exposure to violence.Physical rehabilitation service users who lacked social support prior to receiving MHPSS were more likely to report a large reduction in symptoms of depression following MHPSS.The study underlines the importance of social support, particularly peer support, in addressing MHPSS needs.

Mobile Medical Teams are Often Over-Qualified.

BACKGROUND AND IMPORTANCE: Emergency department (ED) staff in Belgium is simultaneously involved in patient care in the ED and in prehospital interventions as part of a Mobile Medical Team (MMT) or a Paramedic Intervention Team (PIT). There is a growing concern that the MMT is often over-qualified for the prehospital interventions they are dispatched to, while their absence from the ED results in insufficient human resources there. OBJECTIVE: The current study aims to investigate whether this perception is correct in the EDs of two different regions, while also examining the differences between a two-tiered (2T) and a three-tiered (3T) Emergency Medical Services (EMS) region. METHODS: A specially developed and pre-tested registration form was completed by physicians and nurses before and after each MMT intervention. The form included information on the composition of the MMT, the perceived need for MMT intervention pre-departure from the ED, the subjective appreciation of the need for the MMT after an intervention, and the therapeutic intervention(s) performed, in order to obtain a more objective appreciation of the actual need for an MMT. Data from a 2T and a 3T region were analyzed to rate the appropriateness of the interventions. RESULTS: Although the 2T and 3T regions showed differences regarding MMT composition, dispatching, and logistics, the outcome of the study was identical in both regions. Before the intervention, physicians and nurses estimated that the MMT intervention would not be necessary in 37.7% of cases. However, following the intervention, it was subjectively deemed unnecessary in 65.7% of cases. Based on therapeutic interventions performed, the MMT was viewed as being over-qualified for carrying these out in 85.6% of cases. Post-intervention, the initial prediction that the MMT was over-qualified for the call was confirmed by the same physicians and nurses in 87.6% of cases, whilst their prediction was correct in 92.8% of cases in terms of the intervention that was carried out. CONCLUSION: In two different Belgian regions, the MMT is over-qualified in a vast majority of interventions. Physicians and nurses within the MMT can generally already predict that the MMT is over-qualified when leaving the ED. These findings suggest that there may be significant opportunities to improve the efficacy of human resources in the ED once there are less interventions carried out by an over-qualified MMT.

Creating realistic nerve agent victim profiles for computer simulation of medical CBRN disaster response.

In the last decades, Chemical, Biological, Radiological and Nuclear (CBRN) threats have become serious risks prompting countries to prioritize preparedness for such incidents. As CBRN scenarios are very difficult and expensive to recreate in real life, computer simulation is particularly suited for assessing the effectiveness of contingency plans and identifying areas of improvement. These computer simulation exercises require realistic and dynamic victim profiles, which are unavailable in a civilian context. In this paper we present a set of civilian nerve agent injury profiles consisting of clinical parameters and their evolution, as well as the methodology used to create them. These injury profiles are based on military injury profiles and adapted to the civilian population, using sarin for the purpose of illustration. They include commonly measured parameters in the prehospital setting. We demonstrate that information found in military sources can easily be adjusted for a civilian population using a few simple assumptions and validated methods. This methodology can easily be expanded to other chemical warfare agents as well as different ways of exposure. The resulting injury profiles are generic so they can also be used in tabletop and live simulation exercises. Modeling and simulation, if used correctly and in conjunction with empirical data gathered from lessons learned, can assist in providing the evidence practices for effective and efficient response decisions and interventions, considering the contextual factors of the affected area and the specific disaster scenario.

Development and validation of an audit tool for fluid management in non-critically ill adults in the emergency department.

Especially in the emergency department (ED), it is critical to identify weaknesses in prescribing behavior of IV maintenance fluids to ensure a qualitative 24-h fluid management plan. The primary aim of this study was to develop an audit instrument to assess the pitfalls in documentation and prescribing habits of IV fluid therapy for non-critically ill patients admitted to the ED. In this study, an expert panel initially designed the tool. During different phases, adaptations were made to optimize inter-rater agreement (Fleiss' kappa, κ) and validity was determined based on the application of the tool on randomly selected electronic ED patient records. Second, the IV fluid prescription's appropriateness was addressed. The final tool consists of three parts: fluid status assessment, evaluation of maintenance fluid needs and, if present, a limited appropriateness check of the fluid prescription. A manual enhanced inter-rater agreement. κ-values achieved the target value (0.40) after three adaptation rounds, except for the category of 'clinical observations' in the assessment part (κ = 0.531, 95% CI 0.528-0.534), which was acceptable. A check of the IV fluid's indication and volume was only possible with an additional expert evaluation to conclude on prescription appropriateness. Criterion related validity of the final version was high (93.4%). To conclude, the instrument is considered reliable and can be used in clinical practice to evaluate ED fluid management. Thorough documentation is essential to evaluate the appropriateness of the IV fluid prescription, to improve information transfer on IV fluid therapy to the ward and to facilitate retrospective chart review of ED prescribing behavior.
