hesim
is a modular and computationally efficient R package for health
economic simulation modeling and decision analysis that provides a
general framework for integrating statistical analyses with economic
evaluation. The package supports cohort discrete time state transition
models (DTSTMs), N-state partitioned survival models (PSMs), and
individual-level continuous time state transition models (CTSTMs),
encompassing both Markov (time-homogeneous and time-inhomogeneous) and
semi-Markov processes. It heavily utilizes Rcpp
and data.table
,
making individual-level simulation, probabilistic sensitivity analysis
(PSA), and incorporation of patient heterogeneity fast.
Features of the current version can be summarized as follows:

There are two good places to start:
The Introduction to
hesim
article provides a quick introduction.
Our preprint describes the package (including mathematical details) more thoroughly.
You might also want to explore our example analyses which can be found in the preprint and web articles. They are summarized in the table below, with some drawn from the Decision Modeling for Health Economic Evaluation textbook. Key areas of focus are the (i) statistical models of disease progression (in terms of the baseline risk and relative treatment effects) and (ii) the available data (either individual patient data (IPD) or aggregate-level data).
