For operating rooms (ORs) and hospitals, inventory management of surgical instruments and material handling decisions of perioperative services are critical to hospitals service levels and costs. However, efficiently integrating these decisions is challenging due to hospitals interdependence and the uncertainties they face. These challenges motivated the development of this study to answer the following research questions:(R1) How does the inventory level of surgical instruments, including owned, borrowed and consigned, impact the efficiency of ORs? (R2): How do material handling activities impact the efficiency of ORs? (R3): How do integrating decisions about inventory and material handling impact the efficiency of ORs? Three discrete event simulation models are developed here to address these questions. Model 1, Current, assumes no coordination of material handling and inventory decisions. Model 2, Two Batch, assumes partial coordination, and Model 3, Just-In-Time (JIT), assumes full coordination. These models are verified and validated using real life-data from a partnering hospital. A thorough numerical analysis indicates that, in general, coordination of inventory management of surgical instruments and material handling decisions has the potential to improve the efficiency and reduce OR costs. More specifically, a JIT delivery of instruments used in short-duration surgeries leads to lower inventory levels without jeopardizing the service level provided.

Mobile assistance systems (MAS) promise to overcome personnel shortages in operating theatres worldwide. A literature review inspired by the PRISMA 2020 method determines the state of the art of MAS, and identifies a lack of application areas for MAS in the operating theatre. Interviews with subject-matter experts aim to investigate application areas for MAS. The results show that most operational tasks refer to material management and patient management. MAS, with their potential to reduce the time needed for material and patient management, and the physical and mental strain of patient management, have great potential in the operating theatre. Keywords: Mobile assistance system, robotics, supportive tasks, operating theatre

“…AGVs have mainly been used in healthcare as service robots that transport medicines or medical supplies [32,33]. Most of the work focused on this area has defined the effectiveness of the disinfection in terms of range of distance and general use, for example in [18,[34][35][36].…”

Design of the System for the Analysis of Disinfection in Automated Guided Vehicle Utilisation

The article’s main goal is to describe the system design for the analysis of disinfection automated guided vehicle (AGV) utilisation so that the AGV’s optimal number can be determined. The simulation was used as the system’s main tool, allowing a relatively objective approach to imitate real system behaviour. With the proposed system, it is possible to determine the utilisation of AGVs and the number of necessary AGVs that carry out disinfection of the premises through the superstructure platforms. In the simulation model, two main modes of disinfection of ground AGV were tested. A regular circuit is carried out at specific intervals as well as a dynamic evaluation of the area and its possible contamination. When the area reaches a certain threshold, the instruction to disinfect the area is triggered. Experiments were carried out for a different number of AGVs, with the possible restriction of entry in the presence of the patient, and for a combination of specialised AGVs. Based on the results, we can conclude that the use of only surface-disinfecting AGVs is limited by the movement of patients and does not bring the same results as the use of a combination of surface- and air-disinfecting specialised AGVs.
