Toward Standardized ICU Trauma Resuscitation via Markov Decision Processes

This study presents a clinically grounded MDP framework for trauma resuscitation that enables RL to be applied retrospectively in critical care. The learned policy mirrored trends previously observed in sepsis, aligning with clinician behavior while exposing variation in vasopressor use. These findings validate the relevance of the proposed MDP in trauma care, demonstrate feasibility of applying RL in this context, and establish a foundation for future modeling, evaluation, and decision support.
