Abstract

Surgery rooms are one of the major activity centers in the hospital. Improving operations management by scheduling can considerably save on expenses.  The purpose of this research was to develop an algorithm for surgery scheduling.


Interviews have been conducted with surgery room's managers, department managers and surgery teams in the hospitals - in which five medical and operational parameters have been set. These parameters represent the values for defining the medical condition of the patient (the severity of his medical condition, medical history, type of anesthesia, patient's age, waiting time). Using these parameters, the patients have been graded and priorities for setting the surgeries' dates were set.

An algorithm for scheduling surgeries has been developed using the patients' grading. This algorithm was tested in two hospitals in the north of Israel. To create a better solution, it is recommended to use an additional criterion while scheduling the surgeries, that is, the duration of the surgeries. The suggested algorithm was conducted in Arena software and scheduled over 200 surgeries.


Results were compared with the actual situation of the surgery room's usage. It has been found that this algorithm gives a better solution by far than the existing situation. The algorithm reached a usage rate of 93% compared to the present usage of 73%. The algorithm worded to MIP- Mixed Intejer Programming in Matlab software and scheduled the surgeries. The usage values reached by this algorithm was 96%-98% but the processing time of this algorithm is very long and not practical in the dynamic surrounding of the surgery rooms layout in the hospitals.
