> NHs are prohibited from requiring a hospitalized resident who is determined medically stable to be tested for COVID-19 prior to admission or readmission.
They were not forbidden from testing them. They were forbidden from requiring one be done as a precondition to come back to the home.
These patients should've been assumed to be potentially infectious by their nursing homes, and placed in dedicated COVID wings with dedicated staff. Nursing homes should be able to practice basic infection control; after all, they have flu season to manage every year.
(The likely reason for this order: limited testing availability, and overwhelmed hospitals in NYC needing beds for the unstable patients, not convalescing nursing home folks.)
