New research letter in Obstetrics & Gynecology from Maggie Lowenstein, Nia Bhadra-Heintz & Penn colleagues: a case series of 15 pregnant/postpartum patients with opioid use disorder switched from sublingual to extended-release injectable buprenorphine.

New study in BMJ Quality & Safety from Bob Burke, LauraEllen Ashcraft, and many collaborators from the VA SAGE team: how do surgical teams discuss "What Matters" conversations with frail older adults before elective surgery? Spoiler: explicit goal clarification is rare in practice.

A new Penn LDI commentary uses a storyline from The Pitt where an AI charting tool hallucinates a patient's history as a jumping-off point for a very real risk: generative AI in medicine can invent facts and propagate errors into genuine patient safety problems.

In a new Penn LDI piece, Eric Bressman uses a scene from The Pitt — where an AI charting tool hallucinates a patient's history — to flag a very real risk: generative AI in medicine can invent facts and propagate errors into genuine patient safety problems.

🏛 Last week, Penn LDI brought together researchers, Congressional staff, and policy leaders for a nonpartisan briefing in Washington, D.C. to examine the evidence on the drivers of high U.S. #healthcare costs and policy approaches to improve #affordability. Stay tuned for key takeaways, coming soon.

Can Facebook wall posts predict cardiovascular disease (CVD) risk? In a new exploratory study, LDI Fellows analyzed linguistic features from Facebook posts and linked them to electronic health records—but found no association with CVD risk. Read more: https://bit.ly/487Yqoy

New HealthAffairs study by Atheen Venkataramani (@atheendar.bsky.social), Paula Chatterjee & Norma Coe: unionization in U.S. nursing homes (2013–2021) led to a substitution effect – LPN staffing rose while RN staffing fell, as management replaced costlier RNs.

New JAMA study finds the Rural Health Transformation Program ($10B/year through 2030) isn't reaching communities that need it most. Half the money is a flat $100M per state, heavily favoring smaller states.

Are #RuralHealthTransformationFund dollars reaching states with the greatest need? A new study by LDI's @rachelwerner.bsky.social#RuralHealthTransformationFundand Paula Chatterjee raises concerns that funds may not target rural residents with the highest clinical burden.

Joseph Nwadiuko (@jnwadiuko.bsky.social) has a new paper in Globalization and Health challenging a key assumption in global health: that economic growth in LMICs reduces physician emigration. The reality is more complicated. 🧵

Proud to highlight this work featured in JAMA (@jama.com) by Penn DGIM's Paula Chatterjee, Rachel Werner (@pennldi.bsky.social), and Eliza Macneal!

Michael Wang (@ncsp-penn.bsky.social) and Paula Chatterjee (Penn DGIM) have a new piece in Health Affairs Forefront on anticipated challenges in safety-net health care financing under the One Big Beautiful Bill Act. 🧵

A ?final thread about our new study measuring financial incentives to treat different racial/ethnic groups. Today’s topic: how this paper came about. I hope the details are helpful for early-career researchers. (1/n) jamanetwork.com/journals/jam...

Congratulations to Eric Roberts, Rachel Werner, and Pete Groeneveld! Eric and Rachel's NEJM article received a 2026 Top Ten Clinical Research Achievement recognition, and Pete's article was a Top Ten Finalist. 🧵

Robin Canada and colleagues' New York Times Opinion piece describes the medical harm — not just social, legal, and moral harm — caused by ICE activities for undocumented patients. Tragic real stories from patients underlie their argument. 🧵

Telehealth may be a critical access point for young adults with opioid use disorder — but it needs to be paired with targeted support. New research published in Addiction Medicine examines buprenorphine retention among young adults accessing telehealth OUD care. 🧵 journals.lww.com/journaladdic...

New JAMA Network Open paper from Bingyu Zhang, David Asch, Kevin Mahoney & Penn colleagues: telemedicine visits were associated with dramatically lower 30-day episode charges than in-person care ($97 vs $509) and fewer follow-up visits. Important findings for how we think about care delivery.

Eric Roberts' article in JAMAHealthForum finds hospital mergers harm Medicaid-covered pregnant women. They traveled farther for delivery, used more safety-net hospitals without NICUs, and had increased delivery trauma—effects not seen among privately insured patients. jamanetwork.com/journals/jam...
