A systematic review of surgical skills transfer after simulation-based training: laparoscopic cholecystectomy and endoscopy.

OBJECTIVE: A systematic review to determine whether skills acquired through simulation-based training transfer to the operating room for the procedures of laparoscopic cholecystectomy and endoscopy. BACKGROUND: Simulation-based training assumes that skills are directly transferable to the operation room, but only a few studies have investigated the effect of simulation-based training on surgical performance. METHODS: A systematic search strategy that was used in 2006 was updated to retrieve relevant studies. Inclusion of articles was determined using a predetermined protocol, independent assessment by 2 reviewers, and a final consensus decision. RESULTS: Seventeen randomized controlled trials and 3 nonrandomized comparative studies were included in this review. In most cases, simulation-based training was in addition to patient-based training programs. Only 2 studies directly compared simulation-based training in isolation with patient-based training. For laparoscopic cholecystectomy (n = 10 studies) and endoscopy (n = 10 studies), participants who reached simulation-based skills proficiency before undergoing patient-based assessment performed with higher global assessment scores and fewer errors in the operating room than their counterparts who did not receive simulation training. Not all parameters measured were improved. Two of the endoscopic studies compared simulation-based training in isolation with patient-based training with different results: for sigmoidoscopy, patient-based training was more effective, whereas for colonoscopy, simulation-based training was equally effective. CONCLUSIONS: Skills acquired by simulation-based training seem to be transferable to the operative setting for laparoscopic cholecystectomy and endoscopy. Future research will strengthen these conclusions by evaluating predetermined competency levels on the same simulators and using objective validated global rating scales to measure operative performance.

Surgical services: shaping future directions.

BACKGROUND: Advances in surgical techniques and anaesthetic practise have facilitated a significant change in the way surgery is currently delivered. In particular, short stay surgery including ambulatory surgery has become the norm for the majority of surgical conditions. However, the planning of surgical services has not always kept pace with nor capitalised on these clinical advances. Like many major urban centres in Australia, the Greater Sydney region is changing, in terms of population growth and configuration of clinical and operational networks. In conjunction with NSW Department of Health, the ministerially appointed Surgical Services Taskforce was tasked with determining the shape and direction of surgery in Greater Sydney over the next 5 to 10 years. METHODS: Over 400 clinicians either attended hospitals forums or were contacted by the Surgery Futures project team. RESULTS: From the consultations, three models of service delivery were strongly advocated. These were the development of high volume short stay surgery centres, the establishment of specialty centres and the expansion of the streaming of planned and emergency surgery. CONCLUSION: These three major recommendations will require a significant reorganisation of surgical services in NSW. However, they are also relevant to surgical services planning elsewhere in Australia. It is imperative that these recommendations are incorporated into long term surgical planning in order to improve the efficiency and sustainability of surgical service delivery.

Making sense of emergency surgery in New South Wales: a position statement.

BACKGROUND: Emergency surgery is a major component of the provision of surgical services and makes up a substantial volume of the workload of surgeons in many hospitals. It is often more complex and surgically challenging than elective surgery. However, little attention has been concentrated on the management or resource requirements of emergency surgery. METHOD: This article identifies principles for models of emergency surgery care and describes how they can be incorporated into a redesign of emergency surgery. They have been developed and are endorsed by experienced surgical staff routinely coping with the challenges of emergency surgery. RESULTS: The benefits of redesigning emergency surgery will be realized by an active partnership between managers, surgeons and surgical teams. The anticipated clinical benefits include improved patient outcomes, enhanced patient and surgical team satisfaction, and increased trainee supervision in emergency surgery. Significant management benefits will ensue from high rates of emergency operating theatre utilization, reduced patient cancellations and reduction in after-hours costs. This unplanned but predictable workload will be managed in a planned and predictable fashion. CONCLUSION: Reform of emergency surgery services is a necessity and not a choice. The development of the emergency surgery guidelines for New South Wales is a step in the right direction. The principles identified in the guidelines should be adapted and implemented across Australia if sustainable, safe and efficient emergency surgery services are to be provided. Patients will expect nothing less.

Applying clinical process redesign methods to planned arrivals in New South Wales hospitals.

*Competing demands of planned and unplanned arrivals present major challenges for hospitals. *Applying clinical process redesign methods to the planned patient journey allows management to recognise the blocks and inefficiencies in the journey and facilitates the development of solutions for improvement. *Redesign of the planned patient journey in New South Wales has promoted the expansion of the extended day-only model of care, reformed the waiting times policy, standardised patient preadmission assessment and preparation, and targeted operating theatre use. *Improved performance management at Area Health Service and local facility levels has accompanied the redesign of planned arrival processes. *The results in redesign of surgery undertaken by the Area Health Services in 96 NSW hospitals have been impressive, with results within 2 years of commencing the clinical services redesign program showing: a 97% reduction in the numbers of patients in Category 1 (admission desirable within 30 days) whose surgery was overdue, from 5308 in January 2005 to 135 in June 2007; and a 99% reduction in the number of patients who have waited > 365 days for surgery, from 10 551 in January 2005 to 84 in June 2007. *Improved surgical service efficiency, safety and quality justify the continuation of the redesign program.

The easiest cut: managing elective surgery in the public sector.

The problem of surgical waiting lists requires multifactorial solutions.

Virtual reality simulators: current status in acquisition and assessment of surgical skills.

Medical technology is currently evolving so rapidly that its impact cannot be analysed. Robotics and telesurgery loom on the horizon, and the technology used to drive these advances has serendipitous side-effects for the education and training arena. The graphical and haptic interfaces used to provide remote feedback to the operator--by passing control to a computer--may be used to generate simulations of the operative environment that are useful for training candidates in surgical procedures. One additional advantage is that the metrics calculated inherently in the controlling software in order to run the simulation may be used to provide performance feedback to individual trainees and mentors. New interfaces will be required to undergo evaluation of the simulation fidelity before being deemed acceptable. The potential benefits fall into one of two general categories: those benefits related to skill acquisition, and those related to skill assessment. The educational value of the simulation will require assessment, and comparison to currently available methods of training in any given procedure. It is also necessary to determine--by repeated trials--whether a given simulation actually measures the performance parameters it purports to measure. This trains the spotlight on what constitutes good surgical skill, and how it is to be objectively measured. Early results suggest that virtual reality simulators have an important role to play in this aspect of surgical training.
