IVI-RA Value Model 2017-11-08T01:49:26+00:00

A Flexible Modeling Platform for Rheumatoid Arthritis

Rheumatoid Arthritis (RA) is the most common autoimmune inflammatory arthritis in adults and often negatively impacts patients’ quality of life and ability to perform daily activities.

To help decision-makers identify high-value treatments for patients with RA, the IVI-RA model simulates the lifetime costs and benefits of different strategies for treating patients with moderate to severe rheumatoid arthritis.

Get Started with the IVI-RA Value Tool

The IVI-RA Value Tool is designed to be a streamlined, easy-to-use interface that helps health care decision-makers evaluate treatments for moderate to severe RA.

How Does the IVI-RA Model Work?

The IVI-RA model is an open-source simulation model that decision-makers can use to assess the value of different sequences of disease-modifying anti-rheumatic drugs (DMARDs). Specifically, the IVI-RA model provides information on expected health benefits, risks and costs for patients with moderate to severe RA.
