Reinforcement learning for treatment decision-making in sepsis: a scoping review.
Machine learning models consistently find sepsis treatment strategies outperforming clinicians, though rigorous clinical testing remains necessary before bedside application.
This scoping review in NPJ Digital Medicine summarizes 72 reinforcement learning studies applying RL to sepsis treatment (vasopressors, fluids, antibiotics, ventilation), finding that MIMIC-based models consistently identify RL policies that numerically outperform clinicians but with significant heterogeneity in design choices and evaluation validity. The review provides a roadmap for RL to clinical practice integration, emphasizing the need for rigorous prospective evaluation and interpretability standards.
