Our research team has conducted a number of impactful studies that have been translated into practice by a range of entities positively influencing health for millions of people. We have designed programs based on our findings that improve both the value and quality of care provided by health plans, employers and health systems.

Impact Story: Penn Medicine

Electronic Health Record Defaults • Generics

Project: Penn Medicine’s EHR Choice

Within Penn Medicine, we changed the default electronic health record (EHR) choice from brand-name prescriptions to generics in a number of practices and found the percentage of generics prescribed increased overnight from about 75% to 98%, saving millions of dollars annually. This study and others like it formed the foundation of the Penn Medicine Nudge Unit, the world’s first health system-based nudge unit, a joint initiative of CHIBE and the Penn Medicine Center for Health Care Innovation.

Other Penn Medicine Nudge Unit highlights include an active choice intervention in the EHR that led to a 37% relative increase in vaccinations; secure text messaging among provider teams leading to a 14% decrease in patient length of stay in the hospital; a change in defaults in radiation oncology leading to a 40% decline in daily CT scan imaging among palliative care patients; and a default change for cardiac rehabilitation that increased referral rates from 15% to 80%.

Impact Story: Baptist Health System

Joint Replacement Surgery • Episode Management

Project: Bundled Payment Models

Working with data from Baptist Health System in Houston, we conducted an observational study following patients who had joint replacement surgery under a bundled payment program offered by CMS, determining that average Medicare expenditures for joint replacement episodes declined 20.8%. Baptist Health was able to drive savings though reductions in internal costs such as artificial joint implants as well as episode management such as reduced institutional post-acute care.
