MethodsĪ Business Process Modeling Notation (BPMN 2.0) was used for the representation of the “OR Process” (being defined as the sequence of all of the elementary steps between “patient ready for surgery” to “patient operated upon”) as a general pathway (“path”). This is highly challenging due to the inherent variable and unpredictable nature of surgery. These goals imply an optimization of planning and a scheduling of the activities involved. Improving cost effectiveness, while maintaining a quality of care, is a universal objective.
The Operating Room (OR) is a key resource of all major hospitals, but it also accounts for up 40 % of resource costs.
