one thing that isn't communicated very much is ICU capacity goes up and down with need. "ICU at 98%" means it's 98% at that point in time, ICU capacity can be added as needed up to a point. In the other direction a hospital can be at 50% ICU capacity, decide they can dial back ICU beds and then percent util jumps even though they may have fewer ICU patients. Hospitals likely have a target ICU utilization and add/remove beds to hit that target as much as possible.
