As a general principle, someone admitted to the hospital unconscious is liable for the cost of the medical services her or she received.
Just imagine the public-policy implications of a rule to the contrary, which would discourage hospitals from admitting unconscious persons brought to the emergency room for treatment!
Also as a general principle, interest accrues on judgments from the date of judgment at a rate set by statute. I am not licensed in Oregon, but cursory research turned up the Oregon statute linked below, which speaks to the question.
Not legal advice, just my two cents. I don't practice law in Oregon or hold Oregon licensure. Consult Oregon counsel to obtain legal advice tailored to your specific circumstance. I practice in Vermont ONLY.
Interest is allowed in Oregon, by statute, at the rate of 9%. This can accrue from the time the bill becomes due, and continues to accrue post-judgment. If you believe that the creditor has incorrectly calculated the interest or is otherwise overcharging you, you should consult with a consumer attorney.

Your situation is an implied contract, and interest is definitely due once the judgment is entered. I would guess it's also due before the judgment, but you should listen to anyone else on AVVO with more specific information. I would also guess the case you cited involved a commercial transaction, with a written contract, where the plaintiff failed to prove interest was contemplated.
The dialogue on this website does not constitute legal advice nor does it form any sort of attorney-client relationship.
