Interaction-Limited Safe Continuous-Time RL for Dynamical Medical Treatment

arXiv:2606. 01051v1 Announce Type: new Abstract: Dynamic medical treatment requires deciding treatment intensity and intervention timing, while patient states evolve continuously and adverse events may occur between clinical interactions.

Offline Reinforcement Learning for Hemodynamic Management of Sepsis in the ICU: a MIMIC-IV Study with Dual Off-Policy Evaluation

arXiv:2608. 16482v1 Announce Type: new Abstract: The dosing of intravenous fluids and vasopressors in sepsis is a sequential decision made under uncertainty and guided largely by clinical judgment, which makes it a natural target for reinforcement learning from historical care.

Robust Reinforcement Learning for Dynamic Treatment Regimes under Model and Measurement Uncertainty

The paper introduces a robust reinforcement learning framework that learns adaptive treatment policies for patients, accounting for uncertainties in biomarker measurements and disease dynamics. By treating the patient as a hidden context, the authors unify generalization and robustness through robust contextual Markov decision processes. Applied to a simulator of metastatic prostate cancer calibrated to clinical data, the resulting policies outperform existing adaptive therapy methods, achieving robustness with minimal performance loss under accurate biomarkers and expected disease evolution, and Pareto-dominating the prior approach across varied scenarios.

Patient-Centered Treatment Planning for Chronic Multimorbidity: A Hierarchical Reinforcement Learning Framework for Preference Modeling

The paper introduces FAHOC, a hierarchical reinforcement learning framework that models patient preferences by learning high‑level therapeutic options and factored intra‑option policies, while enforcing a cooperation‑aware action masking mechanism. It demonstrates that cooperative patients achieve better health outcomes and that the Q‑function approximation error is bounded. Evaluated on data from ~50,000 comorbid hypertension and type 2 diabetes patients, FAHOC improves quality‑adjusted life years by 0.669, correctly identifies cooperative patients 95.9% of the time, and never violates patient preferences in held‑out tests.
