A SSRN pre-print led by CHIBE Associate Director Harsha Thirumurthy, PhD, with additional CHIBE authors: Katy Milkman, PhD; Kevin Volpp, MD, PhD; and Alison Buttenheim, PhD, MBA

This study compiled information on statewide incentive programs along with data on daily vaccine doses administered per 100,000 individuals in each state. The team found that lotteries and other incentives offered by 24 states were not associated with a significant change in COVID-19 vaccination rates.

Wharton Doctoral Candidate Linnea Gandhi also spoke with CHIBE about the results of a recent analysis of the Philly Vax Sweepstakes a large-scale, high-payoff vaccine regret lottery program and why other policy tools such as vaccine mandates may be necessary at this point to boost vaccination rates.

A JAMA Health Forum original investigation led by CHIBE Associate Director Amol Navathe, MD, PhD, and involving several other CHIBE authors: Erkuan Wang, MS; Jingsan Zhu, MS, MBA; Deborah S. Cousins, MSPH; and Rachel M. Werner, MD, PhD

In this investigation, the study authors found that "simultaneous inclusion in both ACOs and bundled payments was associated with lower spending on institutional postacute care, fewer readmissions for medical episodes, and fewer readmissions only for surgical episodes compared with inclusion in bundled payments alone."
A JAMA research letter led by Aditi Vasan, MD, MSHP; with CHIBE authors: Chén Kenyon, MD, MSHP; Christina Roberto, PhD; Alexander Fiks, MD, MSCE; and Atheendar Venkataramani, MD, PhD

"Offline EBT reloading systems were associated with significant relative decreases in WIC participation during the COVID-19 pandemic," the study authors wrote. "These findings...underscore the need for user-centered approaches to benefits design and delivery that minimize barriers to participation for low-income populations."

CHIBE blog post with Devin Brown, a Summer Undergraduate Minority Research (SUMR) Program scholar working with CHIBE faculty

"This project with Dr. Fanaroff examines the ability of behavioral economic approaches — gamification, social support, social accountability, and more — to improve medication adherence for patients with hypertension and hyperlipidemia. We are testing a combination of these approaches to reduce risk factors for cardiovascular disease as a part of a greater project called the Atherosclerotic Cardiovascular Disease Initiative led by Dr. Kevin Volpp, the director of CHIBE," Brown told CHIBE.
