Whenever I get a checkup with my eye doctor, they have me sign a consent-to-treat form. I never gave it a second thought. This last visit, though, the front desk attendant was distracted when I arrived. They knew I was there waiting, but forgot to have me sign. They called me for my appointment, I finished, paid, checked out with the same attendant at the desk, and left.
Now I'm wondering. Does it matter that they forgot to have me sign? Obviously I consented to being treated because I'm an adult and I willingly went with the doctor, so what's the need to have me sign? Is there some reason that an optometrist in the US would have me sign for my consent to treat at every visit when my implied consent is so obviously given? Is there some liability that they reduce by getting my physical signature?
