Several employees at Kings County Hospital have been fired after a disturbing videotape surfaced showing a woman dying in a waiting room, while workers did nothing.

The New York Civil Liberties Union released the video, which was taken two weeks ago. It shows 49-year-old Esmin Green slumping out of her chair and going into convulsions as workers and fellow patients walk by her. She had been in the hospital's psychiatric ward waiting area for more than 24 hours. She was later pronounced dead.

The NYCLU also says hospital workers fudged the time scale of the incident on Green's medical records.

Now the group says the hospital, which is run by the city, will give patients in the waiting room a checkup every 15 minutes, and limit the number of patients to 25 at a time.

"The reason why this woman died the way she did is because there is a culture of indifference to patients that permeates every aspect of KCHC's psychiatric care. Nothing short of that," said civil rights lawyer Rob Cohen.

"I can't explain what happened there," said Mayor Michael Bloomberg of the incident. "I think what they said was, 'Oh well people sleep on the floor all the time and I didn't pay any attention.' They shouldn't be sleeping on the floor, number one, and you should pay attention."

The Health and Hospitals Corporation says it has been adding staffing and addressing overcrowding at hospitals over the past year.
