Infectious risk factors related to Operating Rooms.
Infection control and hospital epidemiology, 1994Co-Authors: Didier Pittet, Georges DucelAbstract:Risk factors related to Operating Rooms include patient-associated risks, the Operating room environment, ventilation systems, cleansing and sterilization, and Operating room personnel. Although constantly debated, surgical wound infection surveillance with appropriate feedback to surgeons is one of the few effective measures that helps reduce surgical infection rates, and we strongly recommend its use. We also recommend the further study of other potential components of effective infection control programs for surgical patients.

Operating Rooms SCHEDULING
International Journal of Production Economics, 2005Co-Authors: Aida Jebali, Atidel B. Hadj Alouane, Pierre LadetAbstract:Abstract Many healthcare institutions have been researching tools to reduce costs and to ensure efficient use of hospital facilities. Operating Rooms are considered among the most costly hospital facilities. In the present work, a two-step approach for Operating Rooms scheduling is introduced. The first step consists of assigning surgical operations to Operating Rooms. The second step consists of sequencing the assigned operations with the objective of improving Operating room use while taking into account the various resource-related constraints and the specifications of the operations processes. Two strategies for operations sequencing are presented: (1) operation assignment to Operating Rooms obtained at the first step is not reconsidered, (2) operation assignment to Operating Rooms is redefined in order to be less constrained. Computational experiments performed on a set of randomly generated problems are used to compare the two strategies.

Planning and scheduling Operating Rooms for elective and emergency surgeries with uncertain duration
Operations Research for Health Care, 2018Co-Authors: Line Ravnskjær Kroer, Karoline Foverskov, Charlotte Vilhelmsen, Aske Skouboe Hansen, Jesper LarsenAbstract:Abstract In this paper we investigate the planning of Operating Rooms at Rigshospitalet, a large Danish hospital. Each operation must be assigned to a specific Operating room and also be scheduled for a specific time while taking into account clinical guidelines. Both elective and emergency operations are included, such that the elective operations are planned while still taking potential emergency operations into consideration. Furthermore, the duration of each operation is uncertain. The aim is to construct robust Operating room schedules that minimise overtime work and release unused capacity. Due to the uncertainty associated with arrival of emergency patients and also the duration of each operation, a deterministic model is not suitable for this problem. Therefore, we develop a stochastic model where operation duration can vary and where the arrivals of emergency patients are unknown. The stochastic model is computationally heavy, so two mixed integer programming based heuristics denoted 2-Step Relax-and-Fix and All Open Relax-and-Fix are developed to solve the problem. The computational study is based on an extensive dataset compromising 304 days. The heuristics give good results with half of the Operating Rooms having less than 8 min of overtime work. To test the robustness of the solutions we carry out a simulated implementation of the operation plans. The simulation shows that the heuristic solutions are fairly robust. In general, results show a clear potential for implementing the method for planning and scheduling of Operating Rooms at Rigshospitalet.

UKSim - Modeling the Effects of Information Quality on Process Performance in Operating Rooms
2010 12th International Conference on Computer Modelling and Simulation, 2010Co-Authors: Ningqiao ShenAbstract:Operating Rooms are regarded as the most costly hospital facilities. Due to rising costs and risks, it is necessary to optimize performance of the Operating Rooms. High quality information has a significant effect on improving process performance and patient satisfaction, as well as resolving patient disputes. Based on the analysis of the operation process, information quality (IQ) is considered as an important contributory factor in improving patient throughput. In this paper, a theoretical framework and main content are presented. Through the establishment of quantitative information, quality indicators such as Trace-ability, Believability and Reputation, and the effect on process performance (registered queue length, waiting time, utilization of hospital facilities), together with the cost of the Operating process, are analyzed from the theoretical aspect and then verified by simulation technology. Finally, the results of our studies provide evidence that simulation can provide effective decision support to drive performance in Operating Rooms in several phases of the IQ improvement.

Evaluation of teamwork in Operating Rooms in a Tunisian university hospital
European Journal of Public Health, 2020Co-Authors: H Lamine, O Ammar, W Mrabet, M A Tlili, W Aouicha, E Taghouti, M Ben Rejeb, Chekib ZediniAbstract:Abstract Background Teamwork is fundamental to ensuring the quality of care and patient safety in Operating Rooms. It has been shown that the occurrence of adverse events is closely linked to a poor quality of teamwork in these settings. Thus, this study aimed to assess teamwork in different Operating Rooms of the university hospital of Sahloul Sousse (Tunisia). Methods It is a descriptive cross-sectional study with convenience sampling, conducted in Operating Rooms of the university hospital of Sahloul Sousse (Tunisia) between February and April 2018. The measuring instrument was the validated observation grid 'Communication and Teamwork Skills Assessment Tool (CATS) '. Teamwork is assessed through 4 domains (Situation awareness, Coordination, Communication, Cooperation). Behaviors are marked in rows each time they occur and are rated for quality in columns labeled “Observed and Good,” “Variation in Quality” (meaning incomplete or of variable quality), and “Expected but not Observed.” Results A total of 51 interventions were observed. Good coordination between the team members was noted, as well as good cooperation within the teams. A variation of quality level of communication with the patient was noted in 31.4% of cases, also communication about the context, the situation and recommendation among caregivers is not quite good with a percentage of 39.2%. Moreover, the work environment was rated as good in 84.3% of cases. Conclusions Some failures in teamwork were noted, hence it is important to take corrective measures for better practice and better patient management in such a complex environment, the Operating Rooms, where there is a strong need for team coordination. Key messages There is a direct relationship between the quality of care and the effectiveness of teamwork. It is necessary to eliminate the barriers to communication, in order to prevent adverse events.

Description of healthcare professionals’ attitudes on patient safety in the Tunisian Operating Rooms
European Journal of Public Health, 2020Co-Authors: M A Tlili, H Lamine, W Aouicha, E Taghouti, M Ben Rejeb, H Sayeh, M Souki, S Chelbi, Thouraya Ajmi, Manel MallouliAbstract:Abstract Background Currently, ensuring surgical safety remain a worldwide challenge. The description of Operating room professionals' attitudes toward patient safety in their work units helps to identify strengths and weaknesses in term of patient safety, allowing a clearer vision of the safety aspects that require special attention. This study aimed to describe healthcare professionals' attitudes on patient safety in the Tunisian Operating Rooms. Methods This is a cross-sectional descriptive study spread over a 6-month period (October-April 2018). It was conducted among healthcare professionals working in the Operating Rooms of the two teaching hospitals of Sousse (Tunisia). The measuring instrument used is the Operating Room Management Attitudes Questionnaire (ORMAQ), which consists of 60 items spread over 8 dimensions. The latter has been subjected to a transcultural validation process inspired from the Vallerand method. Data entry and analysis was done by the Statistical Package for Social Sciences (SPSS.20) software. Results A total of 303 professionals participated in the study (participation rate= 76.13%). The most developed dimension was teamwork and the least developed was “Procedural errors/ compliance”. Items' results show that 94.8% of professionals confirmed that seniors should encourage medical and paramedical staff to ask questions, 53.5% of professionals stated that personal problems can adversely affect their performance and 87.5% agreed that Operating Rooms' team members share responsibilities for prioritizing activities in high workload situations. In addition, 50.9% of participants reported that the managers don't listen to staff or care about their concerns. Conclusions Operating Rooms professionals' attitudes toward patient safety in their work units reflect an alarming situation regarding the quality of healthcare provided to patients. These results should be taken into consideration to guide future intervention on quality management improvement. Key messages Considering human factors is essential to improve safety in Operating Rooms and has an important role in reducing the occurrence of adverse events in these settings. It is important to study the underlying attitudes that determine the human factors for a better understanding and resolution of patient safety problems.
