The effect of decreasing lab turnaround times on emergency department (ED) efficiency can be estimated through system-level simulation models and help identify important outcome measures to study prospectively. Furthermore, such models may suggest the advantage of bedside or point-of-care testing and how they might affect efficiency measures. ⋯ This simulation model suggests compelling improvement in ED efficiency with decreasing lab turnaround time. Outcomes such as time on EMS diversion, ED LOS, and ED throughput represent important but understudied areas that should be evaluated prospectively. EDs should consider processes that will improve turnaround time, such as point-of-care testing, to obtain these goals.

Comparative Study
Simulation in a disaster drill: comparison of high-fidelity simulators versus trained actors.
High-fidelity patient simulation provides lifelike medical scenarios with real-time stressors. Mass casualty drills must construct a realistic incident in which providers care for multiple injured patients while simultaneously coping with numerous stressors designed to tax an institution's resources. This study compared the value of high-fidelity simulated patients with live actor-patients. ⋯ This study demonstrated that simulators compared to live actor-patients have equivalent results in prompting critical actions in mass casualty drills and increase the perceived reality of such exercises.

Advanced medical simulation has become widespread. One development, the adaptation of simulation techniques and manikin technologies for portable operation, is starting to impact the training of personnel in acute care fields such as emergency medicine (EM) and trauma surgery. Unencumbered by cables and wires, portable simulation programs mitigate several limitations of traditional (nonportable) simulation and introduce new approaches to acute care education and research. ⋯ Research agendas in acute care medicine are expanded via portable simulation's introduction of novel topics, new perspectives, and innovative methodologies. Presenting opportunities and challenges, portable simulation represents an evolutionary progression in medical simulation. The use of portable manikins and associated techniques may increasingly complement established instructional measures and research programs at acute care institutions and simulation centers.

Participants in the 2008 Academic Emergency Medicine Consensus Conference "The Science of Simulation in Healthcare: Defining and Developing Clinical Expertise" morning workshop session on developing systems expertise were tasked with evaluating best applications of simulation techniques and technologies to small-scale systems in emergency medicine (EM). We collaborated to achieve several objectives: 1) describe relevant theories and terminology for discussion of health care systems and medical simulation, 2) review prior and ongoing efforts employing systems thinking and simulation programs in general medical sectors and acute care medicine, 3) develop a framework for discussion of systems thinking for EM, and 4) explore the rational application of advanced medical simulation methods to a defined framework of EM microsystems (EMMs) to promote a "quality-by-design" approach. This article details the materials compiled and questions raised during the consensus process, and the resulting simulation application framework, with proposed solutions as well as their limitations for EM systems education and improvement.

Traditionally, professional expertise has been judged by length of experience, reputation, and perceived mastery of knowledge and skill. Unfortunately, recent research demonstrates only a weak relationship between these indicators of expertise and actual, observed performance. ⋯ DP also involves the provision of immediate feedback, time for problem-solving and evaluation, and opportunities for repeated performance to refine behavior. In this article, we draw upon the principles of DP established in other domains, such as chess, music, typing, and sports to provide insight into developing expert performance in medicine.
