CHIBE researchers apply concepts from the field of behavioral economics to design, implement, and evaluate interventions that improve health and build knowledge about efficacy, cost and effectiveness.
The Basic Science Core aims to support laboratory or low-cost field studies that will shed light on mechanisms that can generate behavior change. In contrast to previous large-scale field studies, which have often combined multiple mechanisms into one intervention in order to maximize impact on behavior, basic science projects supported by the Core focus on disentangling and precisely identifying the impacts of individual mechanisms.

There is growing evidence of strong associations between a patient’s social environment and health behavior. Social forces are worth harnessing as a strategy to promote health behaviors because patients usually engage with their physicians and nurses during occasional health system visits, but they interact with their social networks much more frequently. Furthermore, social forces may be particularly effective at building enduring habits for healthy behavior and might be cost effective to implement. This study proposes to complete a randomized controlled trial of 200 subjects with diabetes and evidence of poor adherence to a statin medication (<70% medication possession ratio determined through pharmacy records). Study subjects will use GlowCaps to store their statin medication. Study subjects will identify potential Medication Adherence Partners (MAPs) who can receive information about their adherence patterns at enrollment. The primary outcome will be the percent of statin doses taken during the study as measured by the GlowCaps. The secondary outcome will be subjects’ statin MPR during the study.

The goal of this project is to improve medication adherence and health outcomes in post-discharge patients who are recovering from acute myocardial infarctions. Such patients typically have high rates of poor medication adherence and hospital readmissions and are costly to monitor through intensive case management. The intervention will increase medication adherence through use of wireless pill bottles, financial incentives, and social incentives. We are conducting this study in 38 states with 5 major insurer partners. The anticipated result will be improved health outcomes and lower cost.

A five-year, $4,350,000 grant from the Centers for Disease Control and Prevention has established a Prevention Research Center (PRC) at the University of Pennsylvania. The PRC, one of 26 in the nation, will conduct innovative public health and disease management research aimed at preventing chronic disease and reducing health disparities in Southeastern Pennsylvania. This will be the first PRC in Philadelphia.
Among other initiatives, the PRC will conduct a workplace weight loss study to evaluate environmental change strategies and incentives for decreasing obesity and preventing cardiovascular disease in employees of the City of Philadelphia, Independence Blue Cross, and the Southeastern Pennsylvania Transportation Authority (SEPTA).

Financial incentives have been shown to be effective at improving patient health behaviors including medication adherence in a wide variety of contexts. The delivery of such incentives has been enhanced by the recent development of new wireless technologies that facilitate the measurement of daily medication adherence and the provision of incentives in an automated fashion. However, the relative effectiveness of incentives based on process (e.g. statin adherence) versus outcome (e.g. improvements in LDL cholesterol) is unknown.This is a randomized controlled trial to evaluate the relative effectiveness and cost-effectiveness of improving cholesterol levels among participants who are at high risk of CVD and who have elevated LDL cholesterol levels by testing process versus outcomes financial incentives.

This Roybal pilot is a randomized, controlled trial to compare the effects of four interventions on the rate of organ donor registration by members of the general public who visit the DMV website for business unrelated to organ donor registration.

This project will develop and pilot a three month randomized control trial (RCT) of a Motivational Interviewing (MI)‐informed SMS intervention tailored to patient level of activation in a population of patients with poorly controlled type II diabetes. The pilot will inform the development of a larger RCT, powered to detect a change in glycemic control.
