Beware of this claim:
«A US resident in a Long-Term Care Facility (LTCF) has a median length of stay (LOS) of 5 months until death, so if they die of COVID-19 it& #39;s no big deal»
It& #39;s false.

First the definition of LTCF varies by state, but usually is "nursing facilities, assisted living facilities, adult care centers, intermediate care facilities, and/or other long-term care facilities", see #long-term-care-cases-deaths">https://www.kff.org/health-costs/issue-brief/state-data-and-policy-actions-to-address-coronavirus/ #long-term-care-cases-deaths">https://www.kff.org/health-co...

The claim of a 5-month median LOS comes from this 2010 study: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2945440/
There">https://www.ncbi.nlm.nih.gov/pmc/artic... are 3 flaws with this claim:
Flaw #1: this study only covers nursing facilities, and excludes all other LTCF such as assisted living facilities, adult care centers, etc

Flaw #2: this study only examines the last admission (until death) in a nursing home. That& #39;s why the "at the end of life" terminology is repeated in many places.

In other words a resident may be admitted into a nursing home, stay for a while, return home, and years later is re-admitted, until his death.
Only the second stay ("at the end of life") would be included in the statistics of this study.

Flaw #3: the median is 5 months, but the mean is 13.7 months (see table 2). If the goal is to quantify the amount of life (persons × years) potentially lost to COVID-19, the mean is what we should be looking at, not the median.

More accurate studies on the mean LOS in nursing homes (not necessarily the LOS "at the end of life") show it is around 27 months (eg. https://www.longtermcarelink.net/eldercare/nursing_home.htm">https://www.longtermcarelink.net/eldercare... claims 835 days)

Another study found that on all LTCF (not only nursing homes), the mean LOS was 28.3 months ( https://web.archive.org/web/20190406214411/https://www.ahcancal.org/ncal/facts/Documents/09%202009%20Overview%20of%20Assisted%20Living%20FINAL.pdf)

And the end of the stay does not necessarily conclude with death: only 33.1% of discharges are due to death, see table 6.15.

So only 1 in 3 LTCF residents die after a mean stay of around 27-28 months.
This implies the average life expectancy of an LTCF resident, at the time of admission in the facility, is greater than 27-28 months.
