Obamacare has already transformed Esther Redd's health, like that of thousands of other Americans. Redd had been admitted to Mount Sinai Hospital in New York seven times over six months, spending 24 days there for conditions ranging from kidney failure to high blood pressure and diabetes. Each time she was released, Redd would later miss doctor's appointments and skip medications only to wind up back in the emergency room for basic care. "I was living on the edge," said Redd, a 53-year-old from Harlem. "I wasn't used to going to the doctor."
