Abstract: This research is linked to the research line of Education, Health, and Nursing Policies and Practices and to the umbrella project entitled "Multiprofessional Clinical Simulation: Creation and Validation of Models, Scenarios, and Assessment Instruments". The research was developed through the evaluation of debriefing in the simulated clinical scenario with multiple victims in the hospital environment with undergraduate nursing students, whose objective was to analyze the contribution of debriefing in learning the simulated scenario of care to multiple victims with undergraduate nursing students. The method used was quantitative with a descriptive and transversal design. The results highlight in the characterization of the participants' profile that most of them are female and aged 20-30 years. In the evaluation of the debriefing scales: Debriefing Experience Scale: it is highlighted in the agreement that the debriefing helped to analyze their thoughts; helped to make connections in learning; teacher will allow enough time to verbalize feelings before comments; that they had enough time to clarify the questions and that the teacher made a constructive evaluation of the simulation during the debriefing. In relation to the Rating scale of the debriefing associated to the simulation: it was evident that most undergraduate students agreed that the debriefing identified difficulties in the performance; that it focused on important aspects of the performance; that it reflected my skills; that it identified aspects that should be improved in future performances, and disagreed on not wanting to participate in any further simulation; on feeling disrespected, and on feeling that it was a waste of time. We conclude that the contribution from the results of the evaluation scales is important for the performance of future Nurses through good Nursing practices according to patient safety standards. The relevance of the contribution of the debriefing verified from the results of the evaluation scales is important for the development of technical and communicative skills, and care competencies in an interdisciplinary way. The innovative character of the research: use of active methodologies through clinical simulation. The replicability and social impact of the topic of multiple victim assistance in the hospital setting can be applied in new training courses through clinical simulation with undergraduate students and health professionals, so that they can obtain knowledge about care in mass care with fire and how to proceed in these eventualities.

Emergency preparedness capacity of a university hospital in Ghana: a cross-sectional study

Background The health and safety of people are often endangered during emergencies and disasters. Efficient emergency management systems ensure that mitigation, preparedness, response, and recovery actions exist to preserve the health, safety, and welfare of the public. Failure to carry out appropriate responses can have adverse consequences for both emergency responders and casualties; hence, the need for emergency preparedness. This study sought to assess the state of emergency preparedness capacity of the Kwame Nkrumah University of Science and Technology hospital in Ghana. Methods A facility-based cross-sectional study was conducted between December 2018 and February 2019 using three guidelines developed respectively by the World Health Organization, the Ministry of Health-Ghana, and the Ghana Health Service. The hospital's emergency preparedness was assessed regarding the emergency policies, plan, protocol, equipment, and medications. Results Overall, the hospital's emergency preparedness level was weak (57.36%). Findings revealed that the hospital had inadequate emergency equipment, and supplies for emergency care delivery, especially during upsurge. It also did not have an emergency planning committee. There were noticeable deficiencies in some emergency resources such as chest tubes, basic airway supplies, and many emergency drugs. Other vital emergency tools such as pulse oximeter, thermometer, and emergency medications were inadequate. The hospital had a strong emergency plan and policies on assessment (77.8% and 78%) respectively. Conclusion The Kwame Nkrumah University of Science and Technology hospital is not prepared sufficiently for an emergency surge, and this poses a major health challenge. Emergency items must be made available, and the organization and planning of emergency service provisions must be improved to avoid preventable deaths during an emergency surge.

A simulation research on casualty prediction based on system dynamics and agent-based modeling / 第二军医大学学报

Objective To simulate, predict and analyze the total number, spatial and temporal distribution, and proportion and composition distribution of combat casualties. Methods System dynamics was used to construct an combat process simulation and casualty prediction model. Agent-based modeling was used to import macro casualty data from the prediction model, split the casualty data and assign the combat injury information in a specific proportion. Results The casualty prediction model based on system dynamics could integrate with specific operational mission and analyze the combat influencing factors, weapon destruction performance, and level of protection in both Red and Blue sides. The casual-effect loop and the stock-flow model were constructed on combat process. The degree of damage to the target of the two sides in the battle was transformed to casualty data. We extracted the macro casualty data from the combat casualty prediction model. Through constructing the corresponding relationship between the destruction degree of operational objectives and war wound information of all kinds, we assigned and simulated the traumatic condition of each individual casualty and completed the conversion from casualty to wounded flow. Conclusion Constructed casualty prediction model based on system dynamics and the casualty generating model based on agent can scientifically calculate the spatial, temporal distribution and proportion and composition of casualties.

Research progress in topical hemostatic agents for war injury / 中华创伤杂志

Effective and rapid hemostasis is the key to reduce the mortality of war injuries and has been the focus of tactical war injury treatment (TCCC) in recent years. With the changes of battlefield and trauma, the higher demand for trauma hemostasis promotes the fast development of new hemostasis concept and methods. At present, there are a wide variety of topical hemostasis materials or products with different mechanisms of action, all of which are aimed at first aid, self rescue, and rapid treatment of wounds in wartime. Efficient topical hemostasis materials or products can quickly promote coagulation, prevent serious bleeding, and reduce the death of war injuries, thus being suitable for the field battle. Therefore, it is an inevitable trend to develop highly efficient hemostatic products catering to diverse needs. In this article, we briefly review the mechanism, efficiency, and some deficiencies of several novel hemostatic agents such as chitosan and zeolite, and provide new outlook for the research of current rapid hemostatic products. It provides a theoretical basis for development of hemostasis medical materials and instruments for severe combat trauma, especially penetrating injury or high-energy explosive injury.
