and CTP figure, whichever was highest, because the figures from these systems included all care homes
and not nursing facilities as in the CMS system. In a few cases, the CMS number of deaths exceeded the
KFF and CTP figure. We wanted to achieve high sensitivity in our estimate– capturing as many “true”
COVID-19 linked deaths as possible. We assumed that each death recorded by each source was
accurate. That is, each source was identifying “true” COVID-19 linked deaths. We further assumed that
differences in recorded deaths between sources resulted from differences in the completeness of their
data. For example, the CMS system would have lower deaths recorded for a state than KFF or CTP
because the CMS system collected data only on nursing facility deaths. The KFF and CTP systems could
vary in their figures for a state because they were drawing from different state and local sources.
Even though figures varied at the state-level, the aggregate counts of COVID-19 care home deaths at the
national level were close between KFF with 131,178 deaths in 30,802 care homes and CTP with 133,350
deaths in 29,107 care homes. The CMS figures were substantially lower, as expected, with 102,867
deaths in 14,793 nursing facilities. Since we selected number of deaths separately for each state based
on the maximum number from the three sources, the total for the combined sources was higher than
either source alone. COVID-19 deaths for people not in care homes (217,425) were derived by
subtracting care home deaths from total population COVID-19 deaths.
Our best estimate was a cumulative number of 139,699 COVID-19 deaths in care homes through January
5, 2021. When comparing this figure to the 102,867 deaths in nursing facilities (obtained from the CMS
data), we estimate that of the total care home deaths linked to COVID-19, about 74% of deaths were in
nursing facilities and 26% were in assisted living facilities and other care homes. Based on these data,
the share of all deaths linked to care homes through January 5, 2021 would be 39.12%. Assuming
residents constituted 99% of all COVID-19 deaths in care homes, the number of resident deaths is
estimated to be 138,302, and rate of resident deaths is estimated to be 7.14 per 100 care home
residents.
Information on COVID-19 vaccinations comes from the US CDC COVID-19 Vaccine Tracker and CDC LTC
and Pharmacy Partnership web sites. According to CDC guidelines, residents and staff of nursing homes
and other long-term care facilities, along with healthcare workers, are to receive top priority for
vaccinations. Most states, which can set their own priorities, have followed the CDC guidelines.
The rollout of the vaccines is targeted to “long-term care facilities” defined broadly to include nursing
facilities, assisted living facilities, memory centers and other congregate settings for older or disabled
people. Most vaccinations in long-term care facilities are being administered under contract by major
drug store chains (Walgreens, CVS, and others). They are administered en masse through “clinics” held
on-site in long-term care facilities. Vaccinations are reported as number of doses. A total of 1,384,963
doses, either 1st or 2nd doses, had been administered in long-term care facilities as of January 15, 2021.
A total of 12,279,180 doses (10,595,866 1st, and 1,610,524 2nd) had been administered to the overall
population, including long-term care, as of that date. With the rapid rollout of the vaccines, the numbers
are increasing rapidly.
5. Summary tables and graphs
This section summarises the most recent data from official sources gathered in this document so far, but
needs to be interpreted with the limitations and caveats described above. In Table 1, we have tried to
distinguish the numbers of deaths among care home residents from the number of deaths in care
homes and between confirmed and probable deaths. There are more details on the differences in
sources and definitions of the data provided in this table in the descriptions of the data available for
