Combat Casualty Handoff Automated Trainer (CCHAT)

Combat casualty handoffs are critical communication moments during which responsibility for the patient and important casualty information is transferred between providers. The nature of these handoffs requires specialized training, for which no standardized framework currently exists. The proposed effort aims to develop a capability, compatible with current DoD systems, that provides caregivers with the opportunity to master combat casualty handoff protocols, from the point of injury through the continuum of care. This solution, the Combat Casualty Handoff Automated Trainer (CCHAT), focuses on the verbal communication and proposes a speech recognition system that will automatically assess a trainees handoff performance in real-time.The proposed system will incorporate the speech protocol created by the DHA17B-002 performer. Using this protocol, trainees will perform a handoff in any simulated training environment. Their speech will be captured by the system and interpreted by the software. As the speech is interpreted, it is evaluated against the standardized speech protocol and populated in trainee and instructor user interfaces. These interfaces will provide in-situ performance feedback and AAR metrics. This effort will develop a TRL3 prototype system and demonstrate feasibility of speech recognition for handoff training.
