Relocalización de vehículos en servicios de emergencias médicas: una revisión

Abstract

ResumenEste artículo presenta una revisión de la literatura de los estudios realizados sobre problemas de relocalización de vehículos de Servicios de Emergencia Médica, (SEM). En particular se presenta una descripción básica de las actividades que se realizan en un SEM, la forma como son clasificados este tipo de problemas, los principales componentes que se tienen en cuenta en el diseño de los modelos, los métodos de solución que se han implementado a la fecha y las medidas de desempeño para evaluar las soluciones. Además se discuten los softwares utilizados para su desarrollo, las estrategias para la recolección de los datos que se tienen en cuenta y las técnicas de verificación y validación. Finalmente, se presentan las políticas de relocalización más evaluadas e implementadas.Palabras clave: servicios de emergencia médicos; relocalización; optimización; simulación de eventos discretos.

Hospital selection in emergency medical service systems: A literature review

“…In (16) and in (56) DES and mathematical programming were also identified as the main quantitative methodologies, for the problems of the relocation of vehicles of EMS and the optimization of the emergency rooms, respectively. In (57) the queuing theory was identified to solve the problem of overcrowding in emergency rooms.…”

“…In (9) GPS in ambulances, to determine geographical position, and GIS, to model travel times, are useful to evaluate more realistic contexts and to measure the impact of periodic updating of the positions of rescue teams throughout the day, in terms of costs and punctuality. The importance of the use of GPS and GIS are highlighted, which have allowed obtaining and processing data in real time, necessary to work on the problem of vehicle relocation (16). In (6) to manage over-occupation, a pilot project on the use of ICT that provide real-time data on the workload is underway in Italy.…”

“…Approaches and methods for each strategic, tactical, and operational planning problems are shown (4). A review of the literature on the EMS vehicle relocation problem was carried out, considering policies, solution methods, software and performance measures among others (16). A critical overview of the existing literature on simulation models applied in EMS operations is provided, pointing out the problems considered, the modeling assumptions and the results obtained (9).…”

Planning and performance measurement in higher education: three case studies of operational research application

“…For instance, [44] addresses the three-echelon uncapacitated facility location problem that considers the flow of products from production plants to warehouses and then to clients, minimizing the cost of warehouses location and the cost of production and distribution of the product. A literature review in vehicle relocation for Emergency Medical Services (EMS) is presented in [45]. The authors in [46] present two multiobjective models to locate surveillance cameras in public transportation systems, optimizing the expected number of crimes detected and the image quality of the surveillance system.…”

“…On the other hand, the outcome of daily activities taking place in an Emergency Room (ER) requires not only innovation in medical research but also speed in procedures and promptness in taking the patients to ER to increase their chances to recover well [4,5]. For example, in the case of acute stroke, the benefits of using the rtPa treatment are evident if given in less than 4.5 h after the stroke event [1].…”
