Rochester Epidemiology Project

The Rochester Epidemiology Project (REP) is a unique population health resource and long-established collaborative initiative originating in Olmsted County, Minnesota.

Administratively led by researchers from the Mayo Clinic Department of Health Sciences Research and the Mayo Clinic Robert D. and Patricia E. Kern Center for the Science of Health Care Delivery's Population Health Science Program, the REP medical records-linkage system has incorporated the medical records of more than 500,000 Olmsted County residents over the past 50 years.

The REP collaboration includes Olmsted Medical Center, Mayo Clinic, Mayo Clinic Health System, Olmsted County Public Health Services, Zumbro Valley Health Center and several dental practices in Olmsted County. In recent years, the REP has expanded to include a total of 27 counties in Minnesota and Wisconsin, increasing the linkage to include approximately 1 million individual patient records.

Funded by the National Institutes of Health since 1966, the Rochester Epidemiology Project plays an important role in understanding population health. Using medical records information, researchers can identify what causes diseases and how patients with certain conditions respond to surgery, medication or other interventions. Information from the REP can even help predict what the future might include for patients with specific diseases or medical conditions.

The REP medical records-linkage system has become a treasured resource for many researchers and has played a key role in many long-term research initiatives. The REP supports 23 federally funded research projects.
