I have never heard of remote scribes before, only transcription. It does indeed seem a bit creepy to have some unknown person listening to your appointment.
From what I have seen, typically onsite dedicated scribes are used for hospital settings (like ER). In physician practices, sometimes there is a dedicated scribe, or sometimes an MA is used as a scribe.
I was curious, so briefly checked their website, which claims:
What You’ll Get
By listening to your clinical appointments and keying data in real-time, ScribeEMR clients get their patient’s medical records 90-95% complete by the end of the interaction.
I am a big fan of scribes in general, as it allows the physician to be a physician. However, I would not be satisfied with 90% accuracy in medical records.
They also seem to sell other services as well. I would definitely prefer in person scribes (whether existing staff, or additional staff).
