Hospital Onset CV-19 Updated

These should not be counted as CV-19 hospitalizations or should be put in a separate bucket.  These people clearly weren’t admitted for CV-19, didn’t test positive on admission, but got CV-19 from being in the hospital.  A not insignificant number.  But the number of incidentals is far higher, well over 50% of all hospitalizations now.

Dave’s notes:

1. These charts illustrate the number of Minnesota Covid hospital patients who are defined as having “Hospital Onset Covid”, defined as acquiring Covid only after being hospitalized for 14 days for a non-Covid illness. This post is an update of the hospital onset Covid charts last published here: https://healthy-skeptic.com/2022/05/03/hospital-onset-cv-19-update/.
2. The chart in Fig. 1 illustrates the total number of Covid hospital beds in use each day in Minnesota (blue curve), and the number of Hospital Onset Covid beds in use each day (orange curve). Hospital Onset Covid is defined as the number of people who are admitted for non-Covid reasons and only after being hospitalized for 14 days test positive for Covid.
3. The chart in Fig. 2 illustrates the number of people with Hospital Onset Covid (orange curve) and the percentage of all Covid beds in use which were classified as Hospital Onset Covid (black curve). On 7/14/2022, the most recent day we have data for, 4.9% of all Minnesota Covid patients were classified as Hospital Onset Covid, down from the highest rate of 9.7% on 4/26/2022.
4. The US Department of Health and Human Services publishes a database titled “COVID-19 Reported Patient Impact and Hospital Capacity by State Timeseries” here: https://healthdata.gov/Hospital/COVID-19-Reported-Patient-Impact-and-Hospital-Capa/g62h-syehThis database, in Column 9, contains a number series named “hospital_onset_covid”, defined as “Total current inpatients with onset of suspected or laboratory-confirmed COVID-19 fourteen or more days after admission for a condition other than COVID-19 in this state.”This data set for hospital onset covid, when filtered for Minnesota, and plotted.
5. Note that the number of Hospital Onset Covid patients is the total number of patients who have been hospitalized for 14 days, then test positive for Covid, and are still hospitalized on any given day. This is not the number of patients per day who test positive for Covid after having been hospitalized for 14 days.
6. Note also that Hospital Onset Covid patients are completely different from incidental Covid cases, where a  patient is admitted for a non-Covid condition and then immediately tests positive for Covid. It is believed that incidental Covid cases are a substantial fraction of daily Covid admissions, based on data published in other states.
