In January 2013, the Optum business at Minnetonka-based UnitedHealth Group teamed with the Mayo Clinic to launch a lab in Boston for research to improve the quality and lower the cost of health care. Called OptumLabs, the center was designed to work on "big data" research projects by collaborating with outside groups. In November, OptumLabs announced the U.S. Department of Health and Human Services was joining the initiative — an important step forward, since the federal agency is the nation's largest single health care payer by virtue of the Medicare and Medicaid health insurance programs. Dr. Paul Bleicher is chief executive for the group, which directly employs about 40 people and now partners with more than 20 outside groups. He says some of the research published in the past year shows the promise for OptumLabs going forward.
Q: Can OptumLabs point to any successes where research projects improved the understanding of cost or quality in health care?
A: We've had a number of interesting studies to date. Two of them, actually, came from the Mayo Clinic to address those two topics.
One in the spring of this year was a study that looked at the new anticoagulants … in comparison to the old standard of care warfarin in patients with atrial fibrillation. That study was examining the safety of the medications, especially around bleeding risk.
They were able to do something with the data because there was so much of it and there was so much depth to the data. They were able to identify that bleeding risks changed with these newer anticoagulants in older patients — I believe it was about age 75 where it switched. That's a very important and subtle finding that will hopefully with other evidence make its way into medical practice to help improve the quality of care and the outcomes of care.
The other study, which was very recently published, addressed … the overutilization of hemoglobin A1C testing in individuals who had stable Type 2 diabetes, and found that there was significant over-testing. There's an opportunity for something that is a very common test to be managed into a more appropriate testing interval for reduced costs.
Q: How would you compare the health care industry with other industries in the use of big data?
A: The health care industry is unique in that the ways that data can be used, or the observations that come from data research, require validation in their application in the health of people. If you think of how a Google or a Facebook might approach data research, for example, they could very rapidly cycle through data. They could find some observations and they could test them out in 100 different ways, and see which ones work best, and then modify their programs all behind the scenes.
