Causal loop diagram of the dynamics of emergency and elective admissions competing for vacant ward beds in a hospital. From
Lane, David C. and Monefeldt, C. and Rosenhead, Jonathan (2000) Looking in the wrong place for healthcare improvements: a system dynamics study of an accident and emergency department. Journal of the Operational Research Society, 51 (5). pp. 518-531. ISSN 0160-5682
This is a high level system dynamics model which is built to
determine the dynamic relationships of the FSA and Followups capacity.
Therefore, it can help clinicians to find out the optimistic method in order to
reduce the waiting list. At past clinicians were seeing more FSA patients,
however, after few months, the followups patients overwhelmed the clinics.
Therefore waiting list has been built up again. By running this model,
clinicians can find out the balanced leverage point(s). New Model has been developed, this is a very draft model.
