You should absolutely read Weston Phippen's Tampa Bay Times report on how hospitals quietly allow racism to enter into the doctor/patient relationship:

Syrenthia Dysart entered the hospital room to perform what she thought would be a routine assessment.

Her elderly patient did not fidget, fuss or speak as Dysart checked her breathing, fluids and pulse. While Dysart held her fingers on the woman's wrist, the charge nurse came in and told Dysart to leave.

Dysart didn't understand.

"Because you're black," she recalled the nurse saying.

Apparently, this has been going on in hospitals around the country—Phippen calls it an "open secret"—and previous cases have settled out of court. This is a practice that needs to end. Go read the whole article.
