The IVI-RA Individual Patient Simulation Model
iviRA is an R package that runs the Innovation and Value Initiative's (IVI's) individual patient simulation model for rheumatoid arthritis (RA) (the IVI-RA model). The model simulates the costs, health outcomes, and risks associated with disease-modifying anti-rheumatic drugs (DMARDs) including conventional DMARDs (cDMARDs), biologic DMARDs (bDMARDs), and Janus kinase/signal transducers and activators of transcription (JAK/STAT) inhibitors for patients with moderate to severe rheumatoid arthritis (RA). The model is intended to help decision-makers assess the value of treatments for a population of patients with RA.
iviRA can be installed from GitHub using
# install.packages("devtools") library(devtools) devtools::install_github("InnovationValueInitiative/IVI-RA")
It can then be loaded into
You can also run the model online using our web interfaces.
- IVI-RA Model Interface: full control over treatment sequences, the patient population, model parameters, model structures, and the time horizon.
- IVI-RA Value Tool: a more streamlined experience for users with less experience in decision-analytic modeling and rheumatoid arthritis.
