Markov decision process (MDP) theory dynamically compares Traditional Chinese Medicine (TCM) and Western medicine treatments for acute ischemic stroke (AIS). This method identified optimal treatment combinations, requiring further clinical validation.

Area of Science:

  • Comparative Effectiveness Research
  • Health Informatics
  • Computational Medicine

Background:

  • Non-randomized studies face challenges in capturing dynamic uncertainties.
  • Traditional Chinese Medicine (TCM) and Western medicine combinations are used for acute ischemic stroke (AIS).
  • Markov decision process (MDP) theory offers a novel approach for comparative effectiveness research.

Purpose of the Study:

  • To dynamically compare the effectiveness of various TCM and integrated TCM-Western medicine treatments for AIS.
  • To apply Markov decision process (MDP) theory to analyze patient treatment data over time.

Main Methods:

  • Electronic health records (EHR) from 1504 AIS patients (May 2005-July 2008) were analyzed.
  • Patient records were divided into "state-action-reward" stages at three time points.

  • MDP theory's optimality technique with a finite horizon criterion was employed for dynamic comparison.

    • Main Results:

    • 960 patient records meeting inclusion criteria were utilized in the MDP model.
    • Optimal treatment combinations were identified for 30 distinct patient condition types.
    • The study demonstrated MDP's capability for dynamic treatment effectiveness comparison.

    Conclusions:

    • Markov decision process (MDP) theory enables dynamic comparison of complex treatment intervention effectiveness.
    • Optimal interventions identified require further clinical validation.
    • Exploratory studies using MDP theory in other complex intervention areas are recommended.
