“Long access times1 are a major problem in hospitals around the world. Not only patients requiring urgent attention want to be seen as soon as possible, also patients with an appointment expect to be seen at a short notice. If we can develop cost-effective solutions to reduce access times, budgets do not have to be increased. Such solutions would increase efficiency in the use of available resources rather than requiring investment in additional equipment and staff.
To reduce the access times of an endoscopy department, we developed an iterative combination of Discrete Event simulation and Integer Linear Programming. We developed the method in the Endoscopy Department of the Academic Medical Center in Amsterdam and compared different scenarios to reduce the access times for the department. The results show that by a more effective allocation of the current capacity, all procedure types will meet their corresponding performance targets in contrast to the current situation. This improvement can be accomplished without requiring additional equipment and staff. Currently, our recommendations are implemented.”
