This paper proposes a method to visualize Emergency Department patient flow data in a Virtual Reality (VR) Serious Game (SG) environment. Visualizing the patient flow data will allow patterns and trends that hospitals can use to reduce alternative level of care (ALC) days and increase the acute capacity of the hospital. The method proposes to use Unity to develop two VR visualisations of patient flow to a hospital ED such that hospital staff can determine which of the two visualizations will be the most usable, immersive, and playable. This paper also presents future work that will look at the whole system of a hospital using one years’ worth of patient flow data to develop a usable, immersive and playable Virtual Environment (VE).
