CHICAGO (AP) — Striking new research shows dying blacks and Hispanics have much steeper treatment costs than whites, sobering evidence that racial health-care differences continue right up until death. It’s not that minorities are being charged more than whites. It’s that they tend to get more costly, intensive treatments including feeding tubes and other invasive medical procedures near death. That’s in sharp contrast with what often happens throughout their lives, when minorities are less likely than whites to get aggressive medical care.
