Edition 19: Introduction to Markov Modeling
Dear Healthcare Professionals and Leaders,
In this edition and the upcoming ones, I will continue to simplify concepts from the textbook Essentials of Pharmacoeconomics.
Summary of previous edition
In the last edition, we explored some practical applications of decision analysis in Healthcare
Edition 19: Introduction to Markov Modeling
In this edition and the next, we will explore Markov Modeling, a powerful tool used in pharmacoeconomics to account for diseases that evolve over time and have recurring events. This summary is based on Chapter 10 of Essentials of Pharmacoeconomics, which explains the fundamentals and applications of Markov models in healthcare decision-making.
What is Markov Modeling?
Markov modeling is an advanced decision-analytic technique used to simulate the long-term outcomes of healthcare interventions. It is particularly useful when health events can occur repeatedly or when patients transition between different health states over time. For example, in chronic diseases like diabetes or heart disease, a patient may move between different stages of health, treatment, and disease progression.
The Basics of Markov Models
Markov models are built around the concept of health states. Each patient starts in a particular state (e.g., "Well" or "Sick") and transitions to other states (e.g., "Dead") as time progresses. These transitions occur over predefined cycles (e.g., each month or year). At the end of each cycle, probabilities are used to calculate the likelihood that a patient will transition to another state or remain in the same state.

When to Use Markov Models
Markov models are especially useful in chronic diseases where patients’ health conditions fluctuate over time, and simple decision trees cannot capture the complexity of long-term outcomes. They are also helpful in estimating both the costs and health outcomes associated with different treatments over a lifetime.
In the next edition, we will look at a practical application of Markov models in evaluating treatment options for chronic diseases.
