A cohort model is frequently used in economic evaluation to represent the experience of a simulated cohort of patients who receive (or do not receive) a new therapy. The experience of each individual cohort member is not considered in detail. Decision trees and Markov processes are used to estimate the proportion of the cohort who experience health events or health states over time. Events and their associated costs as well as the costs and utilities associated with health states can be multiplied by the relevant proportion of the cohort and aggregated to summarise the experience of the cohort.
