BACKGROUND AND OBJECTIVE: The growth of the urban population exerts considerable pressure on municipalities’ public managers to focus their attention on providing emergency medical care that meets the growing demand for emergency pre-hospital medical care. Currently, there are a significant number of traffic accidents and other serious occurrences, such as heart attacks, drownings, epidemics, fires and disasters (floods, landslides, earthquakes) that demand a prompt and seamless response from pre-hospital medical care. As a result of such scenario, the present article endeavours to apply a dual-coverage mathematical model (DSM-Double Standard Model) to define the optimal location of the Emergency Medical Service (SAMU) decentralized dispatch bases in Natal/RN and conduct a simulation study to evaluate the displacement of ambulances between such bases. METHODS: The methodological course that was followed by this research constitutes of 12 steps. The location of decentralized bases for sending emergency ambulances was established using the DSM model and the simulation model was performed using the FlexSim© software version 2018 evaluating base coverage in relation to the total number of calls by demand points for different scenarios. RESULTS: The results obtained throughout the research demonstrated the feasibility of redefining the decentralized bases of SAMU/Natal ambulances as a strategy to reduce response time and guarantee compliance with performance parameters established by international organizations (the World Health Organization, for instance, establishes the time of 8 minutes for emergency medical service calls response). The simulation study showed a significant reduction in response time, by up to 60% in some cases. CONCLUSION: The proposition of new locations for the decentralized dispatch bases of the SAMU/Natal can provide an overall significant reduction on the ambulance response time, so as to contribute to expedite the initiation of treatment of patients, if necessary, sent to hospitals.

The Moment

The mission of the emergency medical services is to promote and support a system that provides timely, professional and state-of-the art emergency medical care, including ambulance services, to anyone who is victim of a sudden injury or illness, at any time and any location. A medical emergency has five different phases, namely: population awareness and behaviour, occurrence of the problem and its detection, alarming of trained responders and help rendered by bystanders and trained pre-hospital providers, transport to the nearest or most appropriate hospital, and, if necessary, admission or transfer to a tertiary care centre which provides a high degree of subspecialty expertise. In order to meet these goals, emergency medical services must work aligned with local, state officials; with fire and rescue departments; with other ambulance providers, hospitals, and other agencies to foster a high performance network. The term emergency medical service evolved to reflect a change from a straightforward system of ambulances providing nothing but transportation, to a complex network in which high-quality medical care is given from the moment the call is received, on-scene with the patient and during transportation. Medical supervision and/or participation of emergency medicine physicians (EP) in the emergency medical service systems contributes to the quality of medical care. This emergency medical services network must be capable to respond instantly and to maintain efficacy around the clock, with well-trained, well-equipped personnel linked through a strong communication system. Research plays a pivotal role in defining necessary resources and in continuously improving the delivery of high-quality care. This chapter gives an overview of the different aspects of emergency medical services and calls for high quality research in pre-hospital emergency care in a true partnership between cardiologists and emergency physicians.

Aims: Most out-of-hospital cardiac arrests occur at home with dismal bystander defibrillation rates. We investigated automated external defibrillator coverage of home arrests, and the proportion potentially reachable with an automated external defibrillator before emergency medical service arrival according to different bystander activation strategies. Methods and results: Cardiac arrests in homes (private/nursing/senior homes) in Copenhagen, Denmark (2008–2016) and registered automated external defibrillators (2007–2016), were identified. Automated external defibrillator coverage (distance from arrest to automated external defibrillator) and accessibility at the time of arrest were examined according to route distance to nearest automated external defibrillator and emergency medical service response time. The proportion of arrests reachable with an automated external defibrillator by bystander was calculated using two-way (from patient to automated external defibrillator and back) and one-way (from automated external defibrillator to patient) potential activation strategies. Of 1879 home arrests, automated external defibrillator coverage ≤100 m was low (6.3%) and a two-way bystander could potentially only retrieve an accessible automated external defibrillator before emergency medical service in 31.1% ( n=37) of cases. If a bystander only needed to travel one-way to bring an automated external defibrillator (≤100 m, ≤250 m and ≤500 m), 45.4% ( n=54/119), 37.1% ( n=196/529) and 29.8% ( n=350/1174) could potentially be reached before the emergency medical service based on current automated external defibrillator accessibility. Conclusions: Few home arrests were reachable with an automated external defibrillator before emergency medical service if bystanders needed to travel from patient to automated external defibrillator and back. However, nearly one-third of arrests ≤500 m of an automated external defibrillator could be reached before emergency medical service arrival if the bystander only needed to travel one-way from the automated external defibrillator to the patient.

Background This study explored the emergency medical service (EMS) in rural mountain areas in Taiwan to establish the public health policies in rural mountain areas. Methods This was a retrospective study. Based on mission records available at 3 EMS branches in Ren-Ai and Sinyi townships of Nantou County, we evaluated dispatched status, patient characteristics, and pre-hospital emergency managements. Results From January to June 2011, a total of 765 EMS were dispatched from these 3 mountain branches. Each dispatched EMS team was consisted of one official emergency medical technician (EMT) with EMT II certificate (100%), and one (88.0%) or two (11.2%) volunteers as EMT I personnel. Most of missions were conducted in the daytime and peaked during 10am to 12pm. Patients were characterised with more men and elderly and predominant with non-traumatic medical complains (55.0%). Approximately 38.7% EMS patients required the advanced life support. Of these 3 mountain EMS branches, the mean response time was 15.3±16.9 minutes, the mean management time on site was 6.1±6.9 minutes and the mean transport time was 38.0±15.9 minutes. The response time and transportation time of EMS in rural mountain areas were relatively longer than that in urban towns in Taiwan. Conclusions The rural EMS is under the challenges of providing appropriate and adequate medical care. Each EMS team should be equipped with adequate emergency care facilities and well trained personnel. (Hong Kong j.emerg.med. 2014;21:373-381)
