“…Bottleneck resources of the system are the transporters. Emergencies have been considered in the operating theatre by Lamiri et al (2006) in [10] : a stochastic scheduling model has been presented in this article. In [11] the same problem is solved using a column generation procedure.…”

. Operating theatre scheduling with patient recovery in both operating rooms and recovery beds. Computers and Industrial Engineering, Elsevier, 2010, 58 (5) Operating theatre scheduling with patient recovery in both operating rooms and recovery bedsAbstract : This paper investigates the impact of allowing patient recovery in the operating room when no recovery bed is available. Three types of identical resources are considered : transporters, operating rooms and recovery beds. A fixed number of patients must be planned over a term horizon, usually one or two weeks. The surgery process is modelled as follows : each patient is transported from the ward to the operating theatre. Then the patient visits an operating room for surgery operation and is transferred to the recovery room. If no recovery bed is available, the patient wakes up in the operating room until a bed becomes available. The operating room needs to be cleaned after the patient's departure, before starting another operation. Finally, the patient is transported back to the ward after his recovery. We consider several criteria based on patients' completion times. We propose a Lagrangian relaxation-based method to solve this operating theatre scheduling problem. The efficiency of this method is then validated by numerical experiments. A comprehensive numerical experiment is then performed to quantify the benefit of allowing patient recovery in operating rooms. We show that the benefit is high when the workload of the recovery beds is high.

“…For instance, Utley et al (2003) use generating functions to estimate the bed needs depending on overall levels of elective admissions and emergency arrivals. Lamiri et al (2008) develop a stochastic model for operating room planning to deal with both an elective and emergency demand for surgery. The objective is to assign elective patients to periods so as to minimize the sum of elective patient related costs and overtime costs of operating rooms.…”

This paper develops a two-stage planning procedure for master planning of elective and emergency patients while allocating at best the available hospital resources. Four types of resources are considered: operating theatre, beds in the medium and in the intensive care units, and nursing hours in the intensive care unit. A tactical plan is obtained by minimizing the deviations of the resources consumption to the target levels of resources utilization. Some capacity is reserved for emergency care. To deal with the deviation between actually arriving patients and the average number of patients on which the tactical plan is based, we consider the option of planning a higher number of patients (overplanning). To adapt the tactical plan to the actual stream of elective patients, we also consider flexibility rules. Overplanning and flexibility leads to a weekly schedule of elective patients. This schedule is modified to account for emergency patients. Scheduled elective patients may be cancelled and emergency patients may be sent to other hospitals. Cancellations rules for both types of patients rely on the possibility to exceed the available capacities. Several performance indicators are defined to assess patient service/dissatisfaction and hospital efficiency. Simulation results show a trade-off between hospital efficiency and patient service. We also obtain a rank of the different strategies: overplanning, flexibility and cancellation rules.Keywords: operation theatre planning, intensive and medium care, emergency and elective patients, overplanning, cancellation rules, operational schedule of patients, master surgical schedule.

“…of operating room (OR) department planning and scheduling has always been a popular subject (Dexter et al 2004;Gerchak et al 1996;Guinet and Chaabane 2003;Hans et al 2008;Lamiri et al 2008). As approximately 60% of all inpatient admissions consist a visit to an OR department, and various scarce and expensive resources are involved, it is apparent that its efficiency is paramount.…”

Suitability and managerial implications of a Master Surgical Scheduling approach

Operating room (OR) planning and scheduling is a popular and challenging subject within the operational research applied to health services research (ORAHS). However, the impact in practice is very limited. The organization and culture of a hospital and the inherent characteristics of its processes impose specific implementation issues that affect the success of planning approaches. Current tactical OR planning approaches often fail to account for these issues. Master surgical scheduling (MSS) is a promising approach for hospitals to optimize resource utilization and patient flows. We discuss the pros and cons of MSS and compare MSS with centralized and decentralized planning approaches. Finally, we address various implementation issues of MSS and discuss its suitability for hospitals with different organizational foci and culture.Keywords Master surgical scheduling · Organizational issues · Operating room management · Organizational focus and culture · Health care operations planning and scheduling
