What will you be doing as the MA? I work as an MA at an ophthalmic clinic and I do HPI, history, external portions of the eye exam, refraction, special testing (corneal topography, OCT, visual fields, etc). All of this I do one on one with the patient. I am the one interacting with the patient, and they are interacting with me. That’s the main difference between MA and scribing. Scribing is much more passive. You don’t interact with the patient as much (if at all).
Depending on what you will be doing as the MA, I would choose that. If you will be cleaning rooms, choose the scribe. If your responsibilities are similar to mine (obviously specific to your clinic), choose MA.
