Question ID: 429671
Specifically in one study, a group of people were in hospital for 219
days over a three yr period starting at age 65. Another group in the
same three yr period spent 123 days. Can you provide sources of
information which would predict actuarially the life expectancy for
each of these groups. The life expectancy for this group in 1960 in
Spain was 70 yrs.

I want a reference which will explain the relationship between days
spent in the hospital starting at age 65 and life expectancy.
Specifically, I want to know the average life expectancy of each of
two groups of people (Nmen=Nwomen) at least 65 years old and
completely healthy at the beginning of a three year period of
observation. At the end of three years one group was in the hospital
an average of 123 days, the other group 219 days.
It would seem that this sort of study probably has been done, if only
for insurance actuarial purposes to rate insurance costs.

Dr. John,

Please take a look at this study.

Hospital admissions, age, and death: retrospective cohort study
See the full text here:

See table 3. 
Number of days spent in hospital in the year, two years (cumulative),
and three years (cumulative) before death, England, 1999-2000

Would this reference sere your purpose?
