Jenny,
We've had home health services when they were ordered by my wife's doctor, so home healthcare isn't just for hospice patients, but my wife never received blood or platelet transfusions at home. It wouldn't hurt to ask the doctor and the treatment center whether home transfusions are available. You should also check that it would be covered by insurance.
I assume that you are asking about this for your mom. You were talking
here about whether or not she'd get another port. If she has a port again be sure to mention that when you ask about home transfusions.
