Two REALLY important quotes from this article:

The group is asking hospitals to report numbers of patients who go to the facility because they have Covid-19 and separate those from individuals who go in for other reasons and test positive after being admitted, the two officials said.

While some hospital networks have changed how they input Covid-19 admissions since then, many have not been able to consistently separate individuals who arrive at the facility for non-Covid reasons — for example, for a heart problem or a broken leg — and those who test positive for the virus upon arrival.
