This study is the first to demonstrate that the advantages of value-based care can extend — or “spill over” — beyond MA patients to other Medicare recipients. These benefits include fewer hospitalizations for chronic illnesses, fewer emergency visits, more wellness visits, and better medication adherence.
Researchers, including Optum Health’s Dr. Ken Cohen, studied nine large physician groups that provided care to over 1.4 million traditional Medicare patients between 2016 and 2019.
The study examined two groups of traditional Medicare patients. The first group was treated by doctors who frequently dealt with complex situations. The second group was a smaller, random sample (20%) of patients treated by all other doctors.
Traditional Medicare patients who benefited from Medicare Advantage value-based care practices were:
less likely to have acute hospital admissions
less likely to be readmitted within 30 days
less likely to be prescribed high-risk medications
more likely to adhere to medications for hypertension, diabetes and high cholesterol
less likely to use emergency departments, and 82% more likely to have annual wellness visits
The positive spillover effects benefiting traditional Medicare patients highlight the broader positive impact of accountable, value-based care Medicare Advantage arrangements.
