Concerns about low physician participation in Medicaid have long motivated policy reforms, but the extent to which enrolled physicians actually care for Medicaid patients remains unclear. To assess patterns of Medicaid participation among physicians, we linked physician enrollment files to Medicaid administrative claims from the period 2019–21, focusing on five physician specialties: cardiology, dermatology, ophthalmology, primary care, and psychiatry.

We propose straightforward principles to foster an evaluation-forward operating system that can transform the adoption of clinical artificial intelligence from a leap of faith into a stepwise, trust-building process.

Certain behaviors in markets are unambiguously unethical. In other cases, however, voluntary exchanges that can create gains from trade remain contested on moral grounds, because of what is traded or of the price at which the exchange occurs.

Deliver-EE participants have a five-fold higher risk of food insecurity than typical U.S. older adults (47% vs. 9% based on 2023 national data), defined as the inability to afford a consistently balanced diet.

The impact of tariffs on prescription drug prices has been poorly understood.

Ambient AI “digital scribes” are rapidly moving into routine practice, easing documentation burden and physician burnout.
