Nursing Home Staff Vaccination and Covid-19 Outcomes
The emergence of the delta variant of the covid-19 virus has raised new concerns about nursing home staff as a vector of infection among residents. This is especially true in facilities with low staff vaccination rates, but the actual relationship between staff vaccination rates and resident infection is not well studied. That is why a group of researchers used CMS data on more than 12,000 nursing homes to get some answers. That group of researchers included David Grabowski, Nexus Fellow and professor of public health at Harvard Medical School.
What they found is that in locations with high community transmission of the virus, low staff vaccination rates were associated with a 132% increase in resident cases, a 58% increase in staff cases, and a 195% increase in resident deaths. The relationships were not as strong in areas with low community transmission.
These findings were published in a letter to the editor in the December 2021 issue of the New England Journal of Medicine.
