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

Computerized provider order entry (CPOE) is a system used for placing orders for medications, laboratory tests, and other services, but it does not specifically focus on prescription refills. While it may include medication orders, it is broader in scope and not exclusively an electronic method for sending prescription refills.

Electronic data interchange (EDI) refers to the electronic exchange of business documents in a standardized format between organizations. Although EDI can facilitate communication between pharmacies and healthcare providers, it is not specifically used for sending prescription refills, making it more generalized than the targeted function of e-prescribing.

Computerized charge entry is primarily related to the billing process and involves entering charges for services rendered to patients. It does not pertain to the electronic transmission of prescriptions or refills, thus lacking relevance to the question about sending prescription refills to pharmacies.
