Hello,
Im a newbie python user,
love the way it "just makes sense"
but Im also a working doctor and have been thinking about coumadin
and how to dose it.
I am not sure where to ask this, so I am going to ask on this list for
two reasons
1. I intend to use python to prototype it.
2. There must some serious math dudes on this list or at least know
enough math to let me know what I am talking about or point me in the
right direction.
The question is,
When I adjust coumadin doses I normal have to use whole or half pills
of the medicien the patient already has.
Fer Instance, if a pt takes 5mg of coumadin a day, that's 35mg of coumadin week
and suppose I do a test that says thye are not taking enough coumadin
and to increase the dose by 10%, ie add another 3.5mg but have it
split evenly over the week or at least every other day.
normall, I would say ok
Take 5mg coumadine everty but on mon and thurs day take 7.5mg
(Note the patient only has 5mg tabs, which they can split to make dose
adjust my 2.5)
My question is,
How would I solve this using math instead of geustimating it.
What kind of math am I talking about here?
If this is the wrong list, please point in the right direction.
i've tried googlie for help, but I dont know enough to even formulate it into a
a search expression
Thanks all
