I’ll answer one more time (just for kicks really).
Using my COPD example, a typical readmit for such a patient is shortness of breath. The hospital will treat the patient for the shortness of breath using palliative measures designed to comfort the patient but which do not really treat the condition. The patient could have stayed out of the hospital and received that same palliative care at a fraction of the cost and the same overall outcome in a different setting or at home. But THAT would be stupid, right?
And COPD is the only health condition hospitals treat? And shortness is the ONLY thing even COPD patients go back to the hospital for? Ever? Because you can think of a single instance where readmittance might not be necessary then we kill off everybody else? YOu are one sick puppy - but don’t try going to the hospital more than once to treat it.
If they could receive the same care at home don’t you think they’d want to? Who in their right mind wants to be in a hospital instead of their home? And if the care was available at home then insurances wouldn’t cover the hospital stay.
You are not making sense in your imaginary scenario.
