Here, I’ll break down hospitalization data, and explain why we must avoid drawing conclusions or drafting policy based on these data *alone* https://www.axios.com/coronavirus-hospitalizations-increasing-abc7e1f7-51b1-4b5c-a2e8-ab55685ac522.html?utm_campaign=organic&utm_medium=socialshare&utm_source=twitter
The first thing to note about hospitalization data is that both the numerator and denominator change on a day-to-day basis. Let’s start by looking at the numerator:
Most #COVID19 hospitalizations occur 8 - 12 days after the onset of symptoms

The treatment of COVID-19 has changed over time.

There are now two treatments that are proven to be helpful in managing #COVID19 in hospitalized patients:
Remdesivir has been shown to reduce the typical (median) amount of time patients spend in the hospital from 15
10 days

Taken together, we expect #COVID19 hospitalizations to be shorter today, than they were in March through June. And that’s exactly what we’re seeing. In Colorado, for example:
ventilator use
length of stay

So, when looking at the number of #COVID19 hospitalizations over time, we must bear in mind that the number of hospitalizations on any given day (numerator) should be lower today, than it was over the summer — *assuming nothing about the disease or the patients has changed.*
I need to step away for a bit, but the upshot so far is:
Shorter #COVID19 hospitalizations translate into fewer people in the hospital for #COVID19 on any given day *so long as community transmission remains the same*
Scientists have found ways to shorten hospitalizations


Shifting gears to the number of hospital beds (the denominator): This value*IS NOT* about bed capacity per se. This value says:
A physical bed exists
A medical team is available to care for the patient


The number of beds available tells us the number of patients that can be *safely* admitted to the hospital (for any reason)
Similarly the number of ICU beds available tells us the number of patients that can be *safely* admitted to the ICU (for any reason)
Key data is missing..

The # does *not* capture whether:
the bed is in a unit or ward that can accommodate #COVID19 patients
the *available* staff has the training to safely care for COVID patients
adequate PPE is available
These factors
*actual* bed available

These factors

CC @meganranney @Cleavon_MD
These factors are most relevant for non-ICU patients, but that’s where “swing” beds come into play— swing beds are one reason why the denominator can change.
There are two definitions of “swing” beds — here we use it to mean regular beds that can be made into “ICU-level” beds.

There are also physical beds scattered throughout a hospital that aren’t technically meant to be assigned to a patient that will be staying overnight — like an emergency room.
Taken together, these “extra” beds comprise a hospital’s “surge capacity” — they
*actual* beds

To recap — there are multiple factors that
and
*actual* hospital bed capacity. These factors affect every level of care, from the emergency room all the way to the ICU.
@TXMedCenter does an exceptional job of breaking down *actual* ICU numbers

Best I can tell, neither state agencies nor HHS is consistently reporting *actual* #COVID19 bed availability.
When I was still working closely w/ FEMA, they were using @DefinitiveHC’s dataset, but key details are opaque since HHS changed things in July: https://www.aha.org/news/headline/2020-08-03-hhs-updates-covid-19-guidance-and-faqs-hospitals-daily-data-reporting

What we *do know* is that hospitals are reporting these key details to HHS via their new system.
We know that based on the guidance document issued by HHS to hospitals: https://www.hhs.gov/sites/default/files/covid-19-faqs-hospitals-hospital-laboratory-acute-care-facility-data-reporting.pdf
We know that based on the guidance document issued by HHS to hospitals: https://www.hhs.gov/sites/default/files/covid-19-faqs-hospitals-hospital-laboratory-acute-care-facility-data-reporting.pdf
We also know that HHS is collecting information about the availability of PPE on a weekly basis, and the information they collect is remarkably specific — including whether the hospital anticipates a shortage, whether staff reuse PPE, and more.
What we don’t know is what @HHSGov does with that information— and why key details are not made available to the public.
To date, HHS has limited public datasets to an *estimated* hospitalization count at the state level.

In summary, drawing conclusions or changing policy based on #COVID19 hospitalization data is fraught with caveats, data gaps, and pitfalls.
We further established that HHS collects the data we need but fails to make that data publicly available…

Final thoughts:
I fail to see why @HHSGov desires to keep the American people in the dark vis Ă vis real-time hospitalization data (there are easy ways to make the data available without compromising patient privacy)
PPE inventories should also be public

Examples of why this matters:
Hospital data transparency sheds light on interdependencies, helps
scarce resources
Right now we’re not getting the full picture, the data can’t tell a complete story
By the time we’re aware of a problem, it’s already too late
