Abstract

The Eugene McDermott Center for Pain Management at the University of Texas Southwestern Medical Center has an interdisciplinary pain management program for chronic pain. This program treats patients with a holistic view of reducing chronic pain and improving their physical, mental, and social well-being through treatment interventions. The development of an adaptive treatment decision tool is main goal of the research project. This program is modeled as a two-stage adaptive treatment decision problem, with state transition models representing the transition of patient state, treatment, and outcome variables from stage 1 to stage 2. Interactions between the patient state and treatments play a major role in determining a personalized treatment plan for individual patients. In this research, we address the challenge of modeling state-treatment interactions. We propose a LASSO based approach to develop the state transition models. The proposed approach is studied using a simulated case study structured based on the McDermott Center data. The state transition models built using the proposed method are then formulated within the multi-objective two-stage stochastic programming optimization to obtain an optimal treatment plan.
