Physicians Prescribe Less Brand Name Drugs When Electronic Health Record Default Settings Show Generics First, Penn Medicine Study Finds

Findings Point to Simple Strategy to Cut Drug Costs, Reduce Unnecessary Health Care Spending

PHILADELPHIA – Programming electronic health records to make generic drugs the default choice when physicians write prescriptions may offer one way to reduce unnecessary spending and improve health care value in the face of spiraling U.S. health expenditures, according to a new study from researchers in the Perelman School of Medicine, The Wharton School and the Center for Health Incentives and Behavioral Economics (CHIBE) at the University of Pennsylvania, and the Philadelphia VA Medical Center. The study is published in a special issue of Annals of Internal Medicine featuring research from Robert Wood Johnson Foundation (RWJF) clinical scholars on innovative high-quality and high-value health care initiatives.

“Prescribing brand-name medications that have a generic equivalent is a prime example of unnecessary health care spending because in most cases, generic medications are less expensive, similar in quality and may actually lead to better outcomes than brand names because of higher rates of patient adherence to generics,” said lead study author Mitesh S. Patel, MD, MBA, MS, assistant professor of Medicine and Health Care Management at Penn who is a graduate of the  RWJF Clinical Scholars Program. “The results of this study demonstrate that leveraging default options can be very effective way to change behavior.”

The study included four ambulatory clinics (two internal medicine and two family medicine) in the University of Pennsylvania Health System between June 2011 and September 2012 and evaluated the difference in prescribing behavior for three commonly prescribed classes of medications—beta-blockers, statins and proton-pump inhibitors—between family medicine and internal medicine physicians. The study looked at a total of 8,934 prescriptions in the pre-intervention period (6,698 from internal medicine and 2,336 from family medicine), and a total of 12,443 prescriptions during the intervention period (9,012 from internal medicine and 3,431 from family medicine). During the intervention phase of the study, the family medicine physicians (17 attendings and 34 residents) continued to be shown  both brand name and generic medication options within the EHR medication prescriber portal, but internal medicine physicians (38 attendings and 166 residents) were shown a different display of only the generic medication options, with the ability to opt out.  When compared to family medicine physicians that did not receive the intervention, internal medicine physicians had a significant increase in generic prescribing rates of 5.4 percentage points for all medications, 10.5 percentage points for beta-blockers, and 4.0 percentage points for statins.

“Not only was changing the default options within the EHR medication prescriber effective at increasing generic medication prescribing, this simple intervention was cost-free and required no additional effort on the part of the physician,” added Patel. “The lessons from this study can be applied to other clinical decision efforts to reduce unnecessary health care spending and improve value for patients.”

The other study authors, all of whom are from Penn, include Susan Day, MD, MPH, Dylan S. Small, PhD, John Howell, III, MD, Gillian L. Lautenbach, MD, Eliot H. Nierman, MD, and Kevin G. Volpp, MD, PhD. Patel’s work on this study was supported by the Department of Veteran Affairs and the Robert Wood Johnson Foundation.

Penn Medicine is one of the world's leading academic medical centers, dedicated to the related missions of medical education, biomedical research, and excellence in patient care. Penn Medicine consists of the Raymond and Ruth Perelman School of Medicine at the University of Pennsylvania (founded in 1765 as the nation's first medical school) and the University of Pennsylvania Health System, which together form a $5.3 billion enterprise.

The Perelman School of Medicine has been ranked among the top five medical schools in the United States for the past 18 years, according to U.S. News & World Report's survey of research-oriented medical schools. The School is consistently among the nation's top recipients of funding from the National Institutes of Health, with $373 million awarded in the 2015 fiscal year.

The University of Pennsylvania Health System's patient care facilities include: The Hospital of the University of Pennsylvania and Penn Presbyterian Medical Center -- which are recognized as one of the nation's top "Honor Roll" hospitals by U.S. News & World Report -- Chester County Hospital; Lancaster General Health; Penn Wissahickon Hospice; and Pennsylvania Hospital -- the nation's first hospital, founded in 1751. Additional affiliated inpatient care facilities and services throughout the Philadelphia region include Chestnut Hill Hospital and Good Shepherd Penn Partners, a partnership between Good Shepherd Rehabilitation Network and Penn Medicine.

Penn Medicine is committed to improving lives and health through a variety of community-based programs and activities. In fiscal year 2015, Penn Medicine provided $253.3 million to benefit our community.
