Future wars are expected to increase traumatic brain injuries (TBI), overwhelming battlefield medics. To help, we developed a TBI Navigator app, using guidelines from sources like the Brain Trauma Foundation and MACE2/MACE-T. This app creates a comprehensive medical record on a mobile phone, transforming guidelines into assessments and management steps. It triggers management recommendations based on patient conditions and is designed for use in resource-limited environments. Interoperable data structures and common terminology allow easy integration of new modules and devices. This app supports the 2023 DoD Data, Analytics, and AI Adoption Strategy, paving the way for commercialization.
