ABSTRACT:
We have developed web-based, multimedia rich, immersive acute trauma patient care simulations using live patient videos. Our objectives include:
a) Improving the decision-making and diagnostic skills of users based on dynamic patient care scenarios;
b) Strengthening learner's radiological interpretation skills;
c) Assessing user competence in the acute management of trauma patients.
The case-based program is integrated in a popular fourth year medical student Emergency Medicine elective at the University of California at Los Angeles (UCLA). Its uniqueness lies in seamlessly integrating a variety of web-based advanced multimedia technologies, to provide the user with an easy to use, immersive, interactive, and cognitively advanced learning experience. These simulations utilize live patient videos, Synchronized Multimedia Instructional Language (SMIL), and QuickTime Virtual Reality (QuickTime VR) to facilitate realizing the objectives of the program. Signed consent was obtained from all patients and hospital staff included in video footage.
Events within each trauma case are presented in the actual chronological order they occurred. While non-linear access is permitted, users are encouraged to follow the case from beginning to end. The case begins with a video presentation of the patient’s arrival, including a narration of symptoms. This is followed by a series of multiple choice questions regarding patient care. A variety of multimedia is used to frame the questions, including synchronized audio narratives, digital videoimagery and animated radiographic images using SMIL technology. Immediate, didactic feedback is provided, consisting of the correct answer and why the alternative choices were incorrect. The case proceeds with the chronological presentation of patient video interwoven with more interactive questions. In conclusion, learners complete a multiple-choice quiz that is dynamically scored and available for review. An evaluation questionnaire is appended in order to elicit student feedback.
Several instructional components are available at all times, including a QuickTime Virtual Reality representation of a trauma resuscitation suite, allowing the user to explore individual components of the suite. This provides the user with an accurate, 360-degree representation of the facilities used for acute trauma patient care. Videos of common surgical procedures are also available.
BENEFIT TO PARTICIPANTS ATTENDING SESSION:
Through a live demonstration, participants will learn about the effectiveness of video in presenting web-based cases. Cognitive features of video based cases will be revealed. Participants will learn from the processes employed in developing rich, immersive cases.
