I cover a 15 bed ICU in one of the states you mentioned and have seen the discrepancy as well.
I noticed, starting in 2020, that our hospital's internal ICU bed-available data did not correlate with local press/internet data. I have access to internal, real-time, system-wide ICU bed-available data. (I'll say that we have some where between 10-25 hospitals, don't want to be specific as I don't know what management would think of posts like this on HN). Our internal system-wide data does not correlate very well with state-wide press/internet metrics either.
When on-shift I spend much time trying to find beds for patients as well as fielding calls from other hospitals that are trying to do the same. The data available on the internet and in the press does not reflect the situation in the trenches at all in our region. I'm not sure how it could as our internal situation changes every 10-15 minutes, sometimes, depending on the progress or deterioration of individual patients, staffing availability, discharges home, numbers of people waiting to be cared for, what day of the week it is (Fri, Sat, Sun, Mon are the worst), how bad the roads are, what time of day it is (most people arrive in the afternoon and evening), if a holiday has just ended, if a large/local event has ended (people tolerate terrible symptoms for holidays and events and come to the ER afterwards).
For the entire pandemic, the real-time in-hospital situation has been more dire than is reflected in the press or on data-accumulation sites like Johns Hopkins. It has been exhausting.
