The National Economic Burden of Rare Disease Study, a collective effort of the rare disease community sponsored by the RARE Foundation, was published in the Orphanet Journal of Rare Diseases as an open-source document available to the community.
Annie Kennedy, Chief of Policy and Advocacy at RARE Foundation, provides an overview of the National Economic Burden of Rare Disease Study during the Rare Disease Congressional Caucus Briefing on Feb. 25, 2021. Annie provides background on the study, the key data from the study, and what these data mean to the community.

About the Study
The study is the first of its kind, providing the most comprehensive assessment of the total economic burden of rare diseases (RDs) in a single year. The results help to ensure that the experience of the rare disease community is reflected accurately in policy discussions. This powerful tool can also increase public awareness of the public health crisis of rare diseases.
What is the Cost of Rare Disease?
Through this research, we estimated the economic cost of 379 rare diseases reached nearly $1 trillion in the U.S. in 2019. To generate the data for this study, we identified both direct medical costs, via an analysis of claims data, and indirect and non-medical costs, via a survey (The Rare Disease Impact Survey) of 1,399 members of the rare disease community.
The National Economic Burden of Rare Disease Study is a defining moment in a decades-long effort to overcome the challenges of rare diseases. This new economic evidence can guide policy decisions with real and lasting benefits for families and society. We must act on it.

What Drives Costs of Rare Disease?
The Study Assessed Three Cost Components to Determine Total Economic Burden of Rare Disease

Direct Medical Costs
Examples
- Inpatient or outpatient care
- Physician visits
- Rx medications and their administration
- Durable medical equipment
Private and public insurance programs typically pay providers directly, and patients are responsible for co-pays

Indirect Costs: Productivity Loss
Examples
- Forced retirement
- Absenteeism
- Presenteeism (when employees cannot fully function in the workplace)
- Reduction in community participation and volunteer service
Reduces income for patients and caregivers, while reducing productivity for employers, communities, society

Non-medical & Uncovered Healthcare Costs
Examples
- Necessary home or auto modifications
- Transportation and education costs
- Paid daily care
- Healthcare services not covered by insurance: experimental treatments, medical foods, and more
Out-of-pocket costs are absorbed directly by families living with RD
What We Found
The Economic Burden of Rare Disease Reached Nearly $1 Trillion in the U.S. in 2019

Indirect and Non-Medical Costs Drive Economic Burden of RD, Exceeding Direct Medical Costs

Indirect Costs of Rare Disease: Productivity Loss
$437 Billion
Productivity Loss Revealed a Massive Economic Toll on Patients, Caregivers, Employers
Balancing a career with medical care is tough. You might not be able to complete everything your manager asks. You might not advance in your position quickly, if at all.”

Non-medical & Uncovered Healthcare Costs
$111 Billion
The Study Also Measured Non-Medical and Uncovered Healthcare –Cost That Includes Things Like Medical Food, Home Modifications, and Transportation.
In Addition to Costs, the Research Captured the Long Diagnostic Journey Facing Patients and Families.

Direct Medical Costs of Rare Disease
$418 Billion
Looking at Direct Costs, Inpatient and Outpatient Care Are Largest Cost Drivers by Category

The financial challenges are overwhelming and unrelenting. The search for a diagnosis or treatment requires navigating a complex medical system and battling with insurance companies all while trying to hold down a job.

What Can You Do?
These findings demand attention from researchers, policy makers, healthcare providers, employers. There is an urgent need to fund research, enhance awareness, and improve access to diagnosis, care, and treatment of rare disease. Contact your elected representatives, share the Study findings, and urge Congress to support important rare disease appropriations priorities that would advance critical rare disease research and therapy development at the National Institutes of Health, the Centers for Disease Control and Prevention, and the Food and Drug Administration.
Make your voice heard: Engage, share your story, and get involved in advocacy.
