Overview

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 (PSMs) and individual-level continuous time state transition models (CTSTMs), as well as summarizing the output of probabilistic sensitivity analysis (PSA). It is designed for high performance simulation modeling and heavily utilizes Rcpp and data.table. hesim is being actively developed and subsequent versions will provide support for cohort-level state transition models.

Features of the current version include:

  • N-state PSMs and individual-level CTSTMs
  • Modeling patient heterogeneity
  • Parameter estimates from either an R based model or from an external source
  • Sampling parameters of a statistical model fit with R using Monte Carlo methods or bootstrapping
  • Parameter uncertainty propagated with PSA
  • Performing cost-effectiveness analyses and representing decision uncertainty from PSAs
  • Simulation code written in C++ to boost performance
