I am working on the following problem. Around 480 patients joined over a
two years period a health information club where they receive health
related advice. We dispose of a data base containing the detailed
medical consumption of the whole population (around 90000 peoples) of
the region they live in. My task is to determine if becoming a member
of the health club will affect one's medical expenses patterns. For
instance: decrease of medicine consumption, increase of preventive
medicine costs.
Did somebody on allstat work on a similar topic and give me any advice
on this issue? I would also be interested on litterature dealing with
similar studies..
My problem is the 480 members did not join at the same time but over a
two years period.
Thank you in advance for answering, best regards.
Dr. C. Farinetto
