 Subject: Predicting lifespan based on the number of days spent in the hospital Category: Health > Seniors Asked by: dr_john-ga List Price: \$100.00 Posted: 05 Jan 2006 16:21 PST Expires: 04 Feb 2006 16:21 PST 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.``` Clarification of Question by dr_john-ga on 06 Jan 2006 15:59 PST ```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.``` Request for Question Clarification by bobbie7-ga on 06 Jan 2006 16:28 PST ```Dr. John, Please take a look at this study.
