Patient flow often described as a systemic issue requiring a systemic approach
because hospital is a collection of highly dynamic, interconnected, complex, ad
hoc and multi-disciplinary sub-processes. However, studies on holistic patient
flow simulation following system approach are limited and/or poorly understood.
Several researchers have been investigating single departments such as ambulatory
care unit, Intensive Care Unit (ICU), emergency department, surgery department or
patients? interaction with limited resources such as doctor, endoscopy or bed,
independently. Hence, this article demonstrates how to achieve system approach in
constructing holistic patient flow simulation, while maintaining the balance
between the complexity and the simplicity of the model. To this end, system
approach, network analysis and discrete event simulation (DES) were employed. The
most important departments in the diagnosis and treatment process are identified
by analyzing network of hospital departments. Holistic patient flow simulation is
constructed using DES following system approach. Case studies are conducted and
the results illustrate that healthcare systems must be modeled and investigated
as a complex and interconnected system so that the real impact of changes on the
entire system or parts of the system could be observed at strategic as well as
operational levels.
