IVI-RA Value Model2018-09-20T06:15:10+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.

Public Feedback Drives Model Development

The Open-Source Value Project allows for iterative and collaborative development of all modeling platforms — including the IVI-RA model — in order to incorporate diverse perspectives.

From sharing your perspective on what factors should be included in our measurement of value to recommending changes to the underlying source code, we encourage continued participation as part of the public feedback process. IVI held an open feedback period on the initial IVI-RA model release. These comments, which represent a range of perspectives, are the basis for upcoming model revisions and will inform future iterations of both the IVI-RA model and future OSVP models.

Setting Priorities for Version 2.0

Following the open comment period on the initial IVI-RA model release, an objective panel of subject-matter experts (the Technical Expert Panel, or TEP) reviewed all feedback and developed recommendations for improving the model in version 2.0. The TEP identified several priorities, including the expanding use of real-world data sources, updating the clinical evidence used, and increasing the flexibility and capacity of the model.

Guided by these recommendations, model improvements are now underway, and IVI-RA Version 2.0 is expected to be released in the second quarter of 2019.

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.
