U.S. should look at how other high-income countries regulate health care costs

A Rutgers University study examines how high-income countries regulate health care costs using a fee-for-service model, finding that structuring negotiations and setting standardized prices can lower US healthcare spending. The study highlights the need for policymakers to address healthcare prices, not just volume of services.

Adverse childhood experiences and at-risk drinking, cannabis, and illicit drug use

Women who experienced at least one adverse childhood experience, such as domestic violence or physical abuse, were more likely to engage in at-risk drinking and illicit drug use. The study highlights the importance of trauma-informed care for urban ER patients, particularly women from low-socioeconomic backgrounds.
