Yeah, I think the red alert status for a hospital on CHATTS website is the closest to usage that can be found right now. Some hospitals in MOCO and PG have been on red alert for days. Johns Hopkins and Bayview were a few weeks ago, but the BMORE hospitals have not been on red alert much over the past week. Again this is for ECG and telemetry beds so it indicates all patients being monitored at the hospital irregardless of disease.
You can query data to see how often each hospital has been on red alert, but the website is a bit slow.
