Clinical Case Index[edit | edit source]

CrashSavers is a gamified educational mobile application, designed to acquire skills for the placement of a tourniquet on a bleeding limb. It consists of an initial interface in which the student is presented with a series of interactive clinical uses that measure the level of knowledge with real-time feedback, in real-time scenarios, in a simulator construction module, and in a self-assessment module.

The clinical cases and the measurement of the learner's knowledge are structured as follows:

  1. Presentation of the case: The case presentation gives the learner identifying data for a simulated patient, the mechanism of trauma, the patient's vital signs at the site of the incident, and a brief physical exam focused on the evaluation of hemorrhage.
  2. Analysis of provided information: The box emphasizes the main points that the student must recognize if they are to correctly resolve the clinical case. Possible diagnoses and an action plan must be considered, which is facilitated by the application through a series of questions that appear on the screen and must be answered by the learner.
  3. Action algorithm: an algorithm of possible action options is presented. In the said algorithm, options framed in red are incorrect; thus, if the student chooses this option the clinical case will stop and the student will not be able to advance in the case. They will receive immediate feedback explaining why their chosen option is incorrect. On the other hand, the correct options will be framed in blue. If the student chooses this option, the clinical case will continue to advance to the next question until the case is complete.

The application also consists of a module with instructions and materials for the proper construction of a bleeding limb simulator, to which a tourniquet must be applied to control bleeding. The application will review the fundamentals of tourniquet application, components involved, and steps to take for proper tourniquet placement. Next, the learner must place a tourniquet on the simulator that they built, and then finally will fill out a self-evaluation survey through the application. They will have to repeat the placement of the tourniquet until they have met all the evaluation points listed in the survey.

Users will create personal accounts, build the simulator, review didactic material, and test their knowledge through decision-making exercises and knowledge measurement created with gamification techniques. Once learners "pass" all the clinical cases in the application, they learn how to apply a tourniquet on a simulator, and then measure their skills acquisition with a checklist that considers 90% correct answers as reflective of an "acquired skill".  

About the App[edit | edit source]

The physical simulator is the core of the psychomotor component of the training, but successful application of an appropriate hemorrhage control technique requires a more complete understanding of the demands of specific clinical scenarios. As such, we have designed a web and phone-based application that includes a gamified environment for learning and user engagement that complements the physical model. The CrashSavers Virtual Application serves as a home base for the user and includes (1) step-by-step instructions on how to construct our low-cost simulator, (2) didactic material on anatomical knowledge and clinical decision making for appropriate hemorrhage control techniques, (3) a virtual simulator to master the steps of these individual techniques, and (4) a self-assessment component.

The game-style application includes didactic material on anatomical knowledge and decision making. Additionally, there is a video instruction on how to appropriately perform the hemorrhage control techniques of interest (pressure, packing, tourniquet use, and foley catheter deployment) based on the simulator and real-life scenarios.

Finally, the educational component of the application will include a virtual simulator to master the steps of these individual techniques. There will also be after completion of all educational modules, users will graduate to perform the skills on the physical simulator model.
