The application of Discrete-Event Simulation (DES) modelling in Malaysia is gradually increasing with the aim of decreasing inpatient treatment lines’ at public funded hospitals. Major premise behind this application is that such simulation models may be exploited in monitoring stroke treatment flows. The objective of this research-in-progress paper is to demonstrate the feasibility of applying DES modelling in understanding treatment line performance of stroke patients in a general inpatient rehabilitation ward at a major tertiary hospital in Kota Kinabalu, Sabah.
