Publication Open Access Operations research helps public health services managers planning resources in the COVID-19 crisis(Sociedad de Estadística e Investigación Operativa, 2020) García de Vicuña Bilbao, Daniel; Cildoz Esquíroz, Marta; Gastón Romeo, Martín; Azcárate Camio, Cristina; Mallor Giménez, Fermín; Esparza, Laida; Estatistika, Informatika eta Matematika; Institute of Smart Cities - ISC; Estadística, Informática y MatemáticasThis article presents the usefulness of operational research models tosupport the decision-making in management problems on the COVID-19 pandemic. The work describes a discrete event simulation model combined with population growth models, which has been used to provide daily predictions of the needs of ward and intensive care unit beds during the COVID-19 outbreak in the Autonomous Community of Navarre, in Spain. This work also discusses the use of the simulation model in non-acutephases of the pandemic to support decision-making during the return to the normal operation of health services or as a resource management learning tool for health logistic planners.Publication Open Access Simulation models to support intensive care unit decision-making in pandemic and non-pandemic times(2022) García de Vicuña Bilbao, Daniel; Mallor Giménez, Fermín; Estadística, Informática y Matemáticas; Estatistika, Informatika eta MatematikaThe aim of this thesis is the construction of simulation models to analyse and improve patient admission and inpatient discharge decisions in an Intensive Care Unit (ICU). These decisions are especially relevant in situations of high ICU occupancy because they can lead to the early discharge of an admitted patient or the redirection of a newcomer. Exceptional circumstances, such as the global COVID-19 pandemic that broke out in 2019, increase the need for ICU beds, making this type of study even more relevant. The development of two interactive simulators has enabled us to understand and support ICU decision-making, both in and out of pandemics.Publication Open Access Safely learning intensive care unit management by using a management flight simulator(Elsevier, 2020) García de Vicuña Bilbao, Daniel; Esparza, Laida; Mallor Giménez, Fermín; Institute of Smart Cities - ISCThis paper presents the development of the first management flight simulator of an intensive care unit (ICU). It allows analyzing the physician decision-making related to the admission and discharge of patients and it can be used as a learning–training tool. The discrete event simulation model developed mimics real admission and discharge processes in ICUs, and it recreates the health status of the patients by using real clinical data (instead of using a single value for the length of stay). This flexible tool, which allows recreating ICUs with different characteristics (number of beds, type of patients that arrive, congestion level…), has been used and validated by ICU physicians and nurses of four hospitals. We show through preliminary results the variability among physicians in the decision-making concerning the dilemma of the last bed, which is dealt in a broad sense: it is not only about how the last available ICU bed is assigned but also about how the physician makes decisions about the admission and discharge of patients as the ICU is getting full. The simulator is freely available on the internet to be used by any interested user (https://emi-sstcdapp.unavarra.es/ICU-simulator).
