T-TRANE is a scenario-based teamwork skills training program for emergency medical teams that uses web-enabled collaborative technologies. The program assumes students are skilled in clinical techniques but have minimal formal knowledge of teamwork. By providing training that focuses on teamwork skills in emergency medical settings, the program is designed to rapidly increase team proficiency. The program is comprised of information about and examples of teamwork skills, and scenario-based training exercises that provide practice in strategies to promote teamwork such as conducting pre-planning and debriefing sessions. T-TRANE is comprised of four modules, with both live (synchronous) interactive sessions and self-paced (asynchronous) sessions that students can complete at their convenience within scheduled intervals. The program includes an Instructor's Guide that provides the designated instructor the necessary support to conduct the training. The approach used in this program can be adapted to any domain in which distributed teams will benefit from pre-deployment training.
