Hospitals and health systems depend on H-1B visa-sponsored physicians. So, what happens now? When President Trump announced a $100,000 fee for all new H-1B visa applications, it sent shock waves through the health care system. Here’s the latest.

Rural areas already facing persistent health care workforce shortages may be “disproportionately impacted by even modest disruptions in international recruitment,” says @rkwadhera.bsky.social. More on how immigration policy shapes the health care workforce.

State of the union’s cardiovascular health: Gains, but not for everyone The American College of Cardiology found uneven gains and sobering declines in heart health. "You can't treat your way out of a prevention problem," an author said.

Here's a cardiologist's nuanced look at why we're (still) not doing better in the U.S. on cardiovascular disease. Q&A with @rkwadhera.bsky.social at @statnews.com

An article titled "The Ambulatory Specialty Model-Imitation or Innovation?" by Andrew S. Oseran, MD, MBA, MSC; Rishi K. Wadhera, MD, MPP, MPhil, published online November 19, 2025, discusses value-based care and the Ambulatory Specialty Model.

💬 Viewpoint: The CMS Ambulatory Specialty Model mandates value-based payment for specialists treating costly chronic conditions. However, issues such as risk adjustment limitations, administrative burdens, and potential inequities remain.

A "JAMA" research letter published online October 29, 2025, shows geographic distribution of healthcare professionals in the U.S. sponsored for H-1B visas, categorized as physicians, advanced practice providers, dentists, and other healthcare workers.

H-1B visa–sponsored physicians are twice as prevalent in rural counties and nearly 4 times as common in high-poverty areas, highlighting the potential harm of rising visa costs to health care access.

Study on Medicaid Work Requirements Finds No Gains in Insurance, Employment State-level findings from Georgia may predict nationwide rollout

Question Has hospital length of stay increased more for Medicare Advantage beneficiaries than for traditional Medicare beneficiaries since the COVID-19 pandemic?Findings In this cohort study involving more than 89 million hospitalizations from 2017 to the third quarter of 2023, Medicare Advantage beneficiaries experienced disproportionately greater increases in extended hospital stays, especially among those discharged to skilled nursing facilities.Meaning These findings suggest that the Medicare Advantage plan design and practices may contribute to hospital discharge delays, with implications for patient outcomes and hospital capacity as enrollment continues to rise.

In health insurers’ race to offload unprofitable members, winners begin to emerge If you’ve followed health insurance earnings lately, you might be experiencing some whiplash. But some lessons about the industry have also emerged.

Sure seems time to examine the purpose of health insurance if this is correct: "Both Humana and CVS’ Aetna, for example, made changes last year designed to drive away 10% of their least profitable Medicare Advantage members."

Private Equity-Backed Hospitals Appear to 'Cherry-Pick' HF Patients Acquired hospitals may be inappropriately selecting patients and doing more profitable cardiac caths.

Private equity-acquired hospitals may be cherry picking low-risk HF patients and performing more profitable cardiac catheterizations. “There’s been growing concern that…they may select for certain types of patients to maximize reimbursement," said @rkwadhera.bsky.social www.tctmd.com/news/private...
