In this study, a feedback intervention increased opioid guideline adherence from 57% to 72% without compromising patients’ ability to manage pain. @jama.com @kitdelgado.bsky.social jamanetwork.com/journals/jam...

With a simple click, doctors can potentially save lives and reduce heart attack and stroke risks for thousands of patients by helping them have their statins on hand. Read more about this impressive Penn project. @acfanaroff.bsky.social @kitdelgado.bsky.social www.pennmedicine.org/news/news-re...

The easy intervention of 90 day vs 30 day prescriptions foundationally changed patterns and addressed some disparities. We can do this in neurology too! #AAN2025

4/ PS - in this study alone, for this one class of medications, changing the default to 90-day supplies meant 57,000 less trips to the pharmacy for our patients! Being a patient on a statin myself, I can tell you it makes it much easier to stay on track

3/ And we appreciate the Editor's Note aligned with the mission of the Penn Medicine Nudge Unit - Making the Right Choice Easy.

Special thanks to Penn Medicine's Kevin Mahoney and the generosity of Adam Berns for enabling this work/

2/ Providing patients with 90-day supplies of their medications (rather than shorter durations) has been shown to increase medication adherence and reduce cardiovascular mortality. The simple default change not only led to 20 percentage point overall improvement, but also reduced disparities...

If you have to take a daily pill to reduce your risk of heart disease, wouldn't it be easier get your meds at the pharmacy 4 days/yr instead of 12?

We made a simple tweak in the default order that made things easier for patients and reduced disparities... 🧵👇#nudge

Tariffs get all the attention, but ask economists what they're really worried about and many will point to the Trump administration's cuts to federal support for the sciences, including canceling grants and revoking student visas.

Throwback to our Penn Medicine Nudge Unit days! We evaluated the effect of a non-EHR nudge to administer CA++ during trauma resuscitations. Great team led by Daniela Schmulevich, Jeremy Cannon, and with @kitdelgado.bsky.social onlinelibrary.wiley.com/doi/full/10....

A study from @agarwalEM @kitdelgado.bsky.social (@UPennEM) Daniel Lee (@pennsurgery.bsky.social) & Zarina Ali (@PennNSG) found that patients who receive an opioid disposal kit after surgery were more likely to dispose of leftover pills than those who did not @pennldi.bsky.social tinyurl.com/3tnne39z

Terminating grants — the Thanos approach.

7/ I'm bullish on the opportunity to optimize behavioral engagement in usage based insurance programs (>$30 billion in premiums in North America in 2024), a true win-win opportunity for business and public health. Thank you to Kelsey Bartalozzi and Katie DeGraff for their partnership at GM. /

6/ ✅ In a subgroup of the participants, we tested the same interventions for reducing handheld phone use while driving. The top performing intervention also reduced phone use by 1 minute per hour, but this subgroup was likely underpowered and result was not statistically significant

5/ ✅ The shared prize approach outperformed an approach that promised a chance in a weekly lottery for the full $125 prize for maintaining a streak, or those merely texted personalized feedback on their buckling habits.

4/ ✅ The total cost of incentives for drivers assigned to this 10-week intervention was only $4.40 per driver—a cost that could be sustained within auto-insurance programs that currently offer billions of dollars in safe-driving discounts each year.

3/ ✅ In a follow-up period after the intervention ended, there was a 33% reduction in unbuckled trips, indicating that the *habit persisted*. This is key!

2/ ✅ Drivers were 26% less likely drive unbuckled when they were promised a share of $125 weekly prize money for maintaining a streak of always buckling up. The weekly $125 prizes were divided among drivers who maintained their perfect streak.

Proud to share our latest work led by Jeff Ebert in partnership with General Motors now out in @amjpublichealth.bsky.social!

RCT w/ 1,100 divers from 49 states

A modest incentive tied to maintaining streaks of seatbelt use led to sustained increase use!

Exciting new paper out today shows that a behavioral
intervention with modest financial incentives led to a sustained increase in seat belt use! 🚗 @kitdelgado.bsky.social ajph.aphapublications.org/doi/epdf/10....

Opioid disposal kits may offer an inexpensive and effective way to impact public safety by reducing excess opioids in the community, a new study by LDI Fellows Zarina Ali, Daniel Lee, @kitdelgado.bsky.social, and Anish Agarwal finds.
