What is E-Prescribing?
Electronic prescribing or e-prescribing is the electronic transmission of prescription information from the prescriber's computer to a pharmacy computer. It replaces a paper prescription that the patient would otherwise carry or fax to the pharmacy. It is believed to improve patient safety by reducing the possibility of a prescribing error due to various causes including poor handwriting or ambiguous nomenclature. Examples of universal ePrescribing clearinghouses in the US include RxHub and Surescripts. Many EHRs send their eprescriptions through these interfaces to the end pharmacy.
How it works
Electronic prescribing is a form of computerized physician order entry. In the US, e-prescribing health information technology is based on standards set forth by NCPDP. The prescriber must have access to computer software developed for this purpose. For example, most electronic medical record systems include e-prescribing features. Orders are usually placed in the exam room while seeing the patient.
