Abstract
Recently, the Lean philosophy is gaining importance due to a competitive environment, which increases the need to reduce costs. Lean practices and tools have been applied to manufacturing, services, supply chain, startups and, the next frontier is healthcare. Most lean techniques can be easily adapted to health organizations. Therefore, this paper intends to summarize Lean practices and tools that are already being applied in health organizations. Among the numerous techniques and lean tools used, this research highlights the Simulation. Therefore, in order to understand the use of Simulation as a Lean Healthcare tool, this research aims to analyze, through the simulation technique, the operational dynamics of the service process of a fictitious hospital emergency unit. Initially a systematic review of the literature on the practices and tools of Lean Healthcare was carried out, in order to identify the main techniques practiced. The research highlighted Simulation as the sixth most cited tool in the literature. Subsequently, a simulation of a service model of an emergency unit was performed through the Arena software. As a main result, it can be highlighted that the attendants of the built model presented a degree of idleness, thus, they are able to atend a greater demand. As a last conclusion, it was verified that the emergency room is the process with longer service time and greater overload.
Highlights
Faced with increased competitiveness and inability to meet demands, health organizations are increasingly seeking structural and organizational changes with the goal of achieving improvements in their performance
McClean et al (2007) showed the use of the Markov Model to identify more efficient patient paths in a hospital that could be associated with health process improvement technologies such as Lean Thinking and Six Sigma. Another approach was suggested by DiGioia et al (2015) who proposed the integration of two approaches, adding the methodology “Patient and Family Centered Care Methodology and Practice” (PFCC M / P) to the Lean filosophy
The first phase consisted of a systematic review of the literature about techniques and tools used in the Lean Healthcare approach, with he objetctiv of identify the main techniques used, among them the simulation
