NEW YORK - Staffers at a Brooklyn hospital falsified medical records and lied to authorities in an attempt to cover up the neglect of a patient who died on the waiting room floor, according to city investigators.

Green, 49, had been languishing in a psychiatric emergency room at the Kings County Hospital for nearly 24 hours when she collapsed from a blood clot.

She lay on the floor for an hour, in full view of nurses, doctors and security guards, before a nurse nudged her body with her foot, then checked her pulse. By then she was dead.

Six hospital employees lost their jobs in the incident, but the probe by the city's main investigative agency raises the possibility that some could also face criminal charges.

The report said that after Green died, a senior nurse at the hospital made three false entries in her medical records to make it appear as though she had been checking up regularly on her patient.

In actuality, the report said, Green had been ignored -- a fact confirmed by security camera footage of her collapse and slow death.

The Department of Investigation said the nurse subsequently admitted in an interview that she fabricated entries in Green's progress notes because she was afraid of losing her job, but lied about the nature of the inaccuracies.
