Bert,
I am not so concerned with the encryption of AC but the electronic transmittal of information from my nurse to patient or vice versa. Updox satisfies my protection in that realm, but I realize there are other ways to do it.
I like having the secure portal, e-fax, and AC all interlinked for efficiency.
But I have included one more link regarding emailing patient info and HIPAA.
