Background: Operating room (OR) is one of the main hospital parts and management of time and cost are very important in this essential unit. Also, due to the close relationship with other departments, improving its service quality and performance, significantly increases the efficiency of hospital. OR is a complex system in which each lack of coordination effects on all hospita...

The cumulative sum (CUSUM) procedure is a graphical method that is widely used for quality monitoring in industrial settings. More recently it has been used to monitor surgical outcomes whereby it 'signals' if sufficient evidence has accumulated that there has been a change in the surgical failure rate. A limitation of the standard CUSUM procedure in this context is that since it is simply base...

Advances in technology have motivated the increasing use of virtual reality simulation-based training systems in surgical education, as well as the use of motion capture systems to record surgical performance. These systems have the ability to collect large volumes of trajectory data. The capability to analyse motion data in a meaningful manner is valuable in characterising and evaluating the q...

A system for intraoperative cone-beam CT (CBCT) surgical guidance is under development and translation to trials in head and neck surgery. The system provides 3D image updates on demand with sub-millimeter spatial resolution and soft-tissue visibility at low radiation dose, thus overcoming conventional limitations associated with preoperative imaging alone. A prototype mobile C-arm provides the...

PERFORMANCE ANALYSIS AND SCHEDULING STRATEGIES FOR AMBULATORY SURGICAL FACILITIES by Xuanqi Zhang Ambulatory surgery is a procedure that does not require an overnight hospital stay and is cost effective and efficient. The goal of this research is to develop an ASF operational model which allows management to make key decisions. This research develops and utilizes the simulation software ARENA b...

While performing a simple task of following: a suture while closing a surgical wound in a simulated environment, we hypothesized that negative reinforcement results in increased procedural errors, longer operating time and poorer trainee satisfaction. We aimed to measure the effect on participant performance and the perception of the instructor, following positive or negative supervisor feedbac...

PURPOSE Our aim was to determine the effect of a surgical technique on biomaterial implant performance, specifically graft retention. METHODS Twelve mini pigs were implanted with cell-free, 1-ethyl-3-(3-dimethyl aminopropyl) carbodiimide (EDC)/N-hydroxysuccinimide (NHS) cross-linked recombinant human collagen type III (RHCIII) hydrogels as substitutes for donor corneal allografts using overly...

Stand-alone and networked surgical simulators based on virtual reality have been proposed as a means to train surgeons in specific surgical skills with or without expert guidance and supervision. However, a surgical operation usually involves a group of medical practitioners who cooperate as team members. To this end, CNVSS have been proposed for the collaborative training of surgical procedure...
