Joan Rivers' Clinic Made Errors

The Manhattan clinic that treated comedian Joan Rivers before her death made a number of serious mistakes, including failing to identify deteriorating vital signs, and providing timely intervention, according to a report released Monday.

The report, issued by the Centers for Medicare & Medicaid Services (CMS), a federal agency, did not mention Rivers by name, but referred an 81-year-old female, or Patient #1.

The description of that patient and the procedures she underwent match what's known about Rivers, including her age and the date of her appointment. CMS declined to say whether the patient referenced in the report is Rivers.
