TL;DR:
Colorectal cancer screening trajectories and projected health outcomes were sensitive to the use of alternate Markov model specifications, demonstrating the importance of examining the memoryless assumption of the first-order Markovmodel when simulating health care utilization over time.

Background Markov models are used in health research to simulate health care utilization and disease states over time. Health phenomena, however, are complex, and the memoryless assumption of Markov models may not appropriately represent reality. This tutorial provides guidance on the use of Markov models of different orders and stratification levels in health decision-analytic modeling. Colorectal cancer (CRC) screening is used as a case example to examine the impact of using different Markov modeling approaches on CRC outcomes.
