Which of the following is an electronic method to send prescription refills to a pharmacy?

Computerized provider order entry (CPOE) refers to a system that allows providers to enter orders for medications and tests directly into a computer. While it may facilitate prescription ordering, it does not specifically focus on the electronic transmission of prescription refills to pharmacies like e-prescribing does.

Electronic data interchange (EDI) is a broader concept that involves the electronic exchange of business documents between organizations, which could include various types of data beyond prescription orders. Although EDI can be used for transmitting prescription information, it is not specifically designed for sending prescription refills, making it less relevant as a direct method for this purpose.

Computerized charge entry deals primarily with the documentation and billing aspects of healthcare services rather than the electronic transmission of prescriptions. This method focuses on capturing charges associated with services provided rather than facilitating the refill of prescriptions, so it does not meet the criteria for the question.
