hesim is an R package for health economic simulation modeling and decision analysis that provides a general framework for integrating statistical analyses with economic evaluation. The package currently supports N-state partitioned survival models and state-transition models, as well as individualized cost-effectiveness analysis. It is designed for high performance simulation modeling including microsimulation and probabilistic sensitivity analysis with core code written in C++ (Website).


The IVI-NSCLC model is an open-source simulation model for assessing the value of sequences of treatment to treat patients with epidermal growth factor receptor (EGFR) positive non-small cell lung cancer (NSCLC). You can can interact with the model in a number of ways:

IVI-RA Model

The IVI-RA model is an open-source individual patient simulation for assessing the value of disease-modifying anti-rheumatic drugs (DMARDs) used to treat rheumatoid arthritis. You can interact with the model in a number of ways:
