I’ve just had a look at the HHS Guidance for Hospital Reporting, and what the HHS has done is replace the National Healthcare Safety Network (NHSN) reporting with “Teletracking” reporting.
The “safety” network was originally the system that monitored the 'safety" of hospitals – they reported to the CDC infections that people acquired while in hospital. I don’t know how that had grown and developed over the years. The new system monitors hospital utilization and particularly COVID-19, which, at least in theory, is something quite different to the original aim of the NHSN.
It may be that the old system wasn’t really fit for the new purpose, or it may be that they noticed that hospital utilization wasn’t really a CDC task, and/or it may be all political – I don’t know.
