True, but a digitally signed document is a good thing.

Because...?

1. You know who wrote it
2. You know that is not corrupted
3. You know when it was written
4. You do not need to store a paper copy
5. It actually does allow real paperless communication

The last two points have nothing to do with digital signing.

If I send a referral electronically either as text in an ordinary encrypted but not digitally signed email message, or by a messaging system such as Medical Objects or Argus but also not digitally signed, that looks as if it came from me, sounds as if it came from me, and asks for a service that that health professional usually provides, do you think that anybody receiving it is likely to question it or to suspect corruption of the message? What I am saying is that I believe that a digital signature adds little in practical terms in day to day use. The only real reason that I see for needing or wanting digital signing is to satisfy the letter of the law for Medicare benefits purposes.
