Abstract

In this paper we focus our analysis on patient flows inside a hospital surgery department, with the aim of supporting the bed re-configuration following an “intensity of care” paradigm. The main contribution of this paper is to develop a Discrete Event Simulation (DES) model which describes the elective and emergent patient flows in a Surgery Department, and is able to evaluate the impact of re-organizing hospital resources within the Department. The model has been applied to reproduce a case study of a General Surgery Department sited in Genova (Italy). Firstly, the model has been used to quantify the impact on a set of performance indicators of the re-organization of a "traditional" stay area into an "intensity of care" one. Following this re-organization the available beds capacity is no longer divided into operating units based on the pathology and medical discipline, but into three different stay areas homogeneous with respect of the complexity of care to be delivered. Secondly, by using the “Optimizer” module, embedded in the Witness simulation software, the best number of beds to be assigned to each Intensity of Care Level (ICL) is determined in order to maximize the number of patients operated. The model development is presented and preliminary results are analyzed and discussed.
