From AZDA Inscriptions:
e-Prescribing can reduce errors. Pharmacists are no longer deciphering handwriting. Phone calls, missed calls and voicemails no longer add steps to the process and the potential for your patient’s prescription getting lost or delayed during the game of “Telephone”
Mandates are in place or on the way to requite eRx for all controlled substances. However the linked article makes a great case that all Rxs should be electronic. I agree.
