Resumen
Emergency hospital services (ED) was the main hospital entrance door and so was the almost obligatory passage for patients before admission in most health units. The practice of blocking admitted patients (patients IP) on stretchers in the corridors of the hospital emergency services for hours or days, called "boarding" causes emergency space and can be harmful to patients. Boarding increases patient morbidity, length of hospital stay, and mortality. In this article, we make the modeling of boarding patients in the emergency department to minimize overcrowding in emergency departments, using a network of queues open to the MMC. The results of this paper help the hospital administration to test alternative policies to improve overall performance.
