Design, development, and evaluation of an online virtual emergency department for training trauma teams.

Background: Training interdisciplinary trauma teams to work effectively together using simulation technology has led to a reduction in medical errors in emergency department, operating room, and delivery room contexts. High-fidelity patient simulators (PSs)-the predominant method for training healthcare teams-are expensive to develop and implement and require that trainees be present in the same place at the same time. In contrast, online computer-based simulators are more cost effective and allow simultaneous participation by students in different locations and time zones.

Design and implementation of rule-based medical models: an In Silico patho-physiological trauma model for hypovolemic shock.

Trauma from 'Dirty' Bomb blasts presents complex clinical problems to healthcare providers who must make critical emergency care decisions with incomplete information, usually limited initially only to cursory observations and vital signs. A set of simple, HFSM patho-physiological models of hypovolemic shock based upon blood volume deficits and remedial therapeutic actions has been created for 10 Virtual World scenarios used for training healthcare personnel in the diagnosis and management of 'dirty' bomb victims. Several general rules define the models: * Virtual patients have individual characteristics of gender, age, health status.

Simulation for team training and assessment: case studies of online training with virtual worlds.

Individuals in clinical training programs concerned with critical medical care must learn to manage clinical cases effectively as a member of a team. However, practice on live patients is often unpredictable and frequently repetitive. The widely substituted alternative for real patients-high-fidelity, manikin-based simulators (human patient simulator)-are expensive and require trainees to be in the same place at the same time, whereas online computer-based simulations, or virtual worlds, allow simultaneous participation from different locations.

Virtual worlds for teaching the new CPR to high school students.

In this study we created a virtual 3D world for learning to manage medical emergencies and evaluated it with 24 high school students in the USA and Sweden. We found that students in both groups felt immersed and found the online simulation easy to use. Scores for flow and self-assessed flow were significantly higher for the RHS group as compared to the HG group (p=.

A framework for evaluating new learning technologies in medicine.

The SUMMIT Evaluation Framework provides a comprehensive model to guide researchers, developers and curriculum decision-makers in conducting the most relevant type of evaluation for a range of learning technologies. In this poster we present the framework and give examples of how we have used it to guide our evaluation efforts.

Collaborative learning using Internet2 and remote collections of stereo dissection images.

We have investigated collaborative learning of anatomy over Internet2, using an application called remote stereo viewer (RSV). This application offers a unique method of teaching anatomy, using high-resolution stereoscopic images, in a client-server architecture. Rotated sequences of stereo image pairs were produced by volumetric rendering of the Visible female and by dissecting and photographing a cadaveric hand.

Comparison of training on two laparoscopic simulators and assessment of skills transfer to surgical performance.

Background: Several studies have investigated the transfer of surgical trainees' skills acquired on surgical simulators to the operating room setting. The purpose of this study was to compare the effectiveness of two laparoscopic surgery simulators by assessing the transfer of skills learned on simulators to closely matched surgical tasks in the animal laboratory.

Study Design: In this post-test-only Control group study design, 46 surgically naive medical student volunteers were randomly assigned to one of three groups: Tower Trainer group (n = 16), LapSim group (n = 17), and Control group (n = 13).

The fundamental manipulations of surgery: a structured vocabulary for designing surgical curricula and simulators.

A structured vocabulary is proposed for supporting the design and development of advanced surgical simulators. Nine fundamental surgical instrument-tissue actions or manipulations are defined and common synonyms provided. The vocabulary focuses on "target skills" that are familiar to surgeons, in comparison with "enabling skills" from the lexicon of instructional designers and psychometricians.

LUCY: a 3-D pelvic model for surgical simulation.

Development of 3-D models of human anatomy for use in virtual reality simulators is anticipated to enhance surgical training. These models may be a valuable resource for gaining mastery of minimal-access procedures. The pelvis portion (hip to upper-thigh) of a 32-year-old female cadaver was frozen and sectioned axially in approximately 2-mm increments as the first step in producing an accurately representative 3-D model of the human female pelvis.

The Stanford MediaServer Project: strategies for building a flexible digital media platform to support biomedical education and research.

Medical media collections are growing at a pace that exceeds the value they currently provide as research and educational resources. To address this issue, the Stanford MediaServer was designed to promote innovative multimedia-based application development. The nucleus of the MediaServer platform is a digital media database strategically designed to meet the information needs of many biomedical disciplines.

Formative design of a virtual learning environment.

Current technology for 3D visualization, modeling and interaction allows the construction of attractive virtual environments for study of anatomy, surgery and other biomedical fields. The formative methodology for designing such environments is uncharted, but necessary before committing to large scale development. We present one such methodology undertaken during the design of a learning environment for biology for high school and middle school students.
