“…Considering all this, a block-scheduling strategy was adopted in this study to avoid negative results, and to ensure patient/surgeon satisfaction in the hospital. When block-scheduling studies [11,15,16,20,[47][48][49] in the literature are examined, it is understood that they want to avoid these negative results.…”

The achievement of health organizations’ goals is critically important for profitability. For this purpose, their resources, materials, and equipment should be efficiently used in the services they provide. A hospital has sensitive and expensive equipment, and the use of its equipment and resources needs to be balanced. The utilization of these resources should be considered in its operating rooms, as it shares both expense expenditure and revenue generation. This study’s primary aim is the effective and balanced use of equipment and resources in hospital operating rooms. In this context, datasets from a state hospital were used via the goal programming and constraint programming methods. According to the wishes of hospital managers, three scenarios were separately modeled in both methods. According to the obtained results, schedules were compared and analyzed according to the current situation. The hospital-planning approach was positively affected, and goals such as minimization cost, staff and patient satisfaction, prevention over time, and less use were achieved.

“…The SPD process described in the previous paragraph was incorporated into an existing simulation model of the OR suite to examine how different block schedules and instrument tray configurations would affect SPD processing times. The simulation model began with the existing simulation model from Nino et al 25 . Figure 3 displays the conceptual model.…”

“…The first dataset contained records for every OR surgery performed over a 3‐year period, totaling 18,071 unique surgeries and 567 different surgical procedures. This dataset was used to fit the probability distributions for the surgical case durations for the OR suite portion of the simulation model 25 . The same information was used for most of the case types in the comprehensive simulation model of the OR and SPD.…”

Discrete event simulation is a well‐established tool for examining the effect of different operating room (OR) block schedules on various performance metrics within the OR suite and adjacent units. However, one unit that has rarely been studied is the sterilization processing department (SPD), which cleans and assembles reusable OR instruments. As part of a larger research study, we developed a series of OR block assignment models that sought to reduce the workload of the SPD and developed a tray optimization model to reduce the number of instruments on increasingly bloated instrument trays. While initial numerical experiments were promising, a comprehensive simulation model of the OR and SPD was needed to more thoroughly examine how potential changes to the block schedule and/or more efficient tray configurations could improve SPD processing times. In this article, we incorporate the SPD into an existing simulation model of an OR suite, which is the first of its kind, and examine the effect that different block schedules and tray configurations have on SPD processing times. Simulation results confirm earlier numerical computations. Furthermore, simulation results suggest that more efficient instrument tray configurations are a much better and more viable method for improving SPD processing time than reconfiguring block schedules.
