On-Call

A specific medication order or action that is dependent upon another medication order or action taking place before it is carried out. For example, “Cefazolin 1 gm IVPB On‑Call to Operating Room.” Since it may be unknown when the Patient will be taken to the operating room, the administration of the On-Call Cefazolin is dependent on that event. This is also a schedule type. See glossary term Schedule Type.

One-Time

A medication order given only one time to a Patient. This medication order type is usually given to the patient within a fixed length of time (e.g., 24 hours). One-time is also considered as a schedule type. See glossary term Schedule Type.

Orange Book Code

The abbreviated name for Therapeutic Equivalence Evaluations Codes. This coding system for therapeutic equivalence evaluations is constructed to allow users to determine quickly whether the FDA has evaluated a particular approved product as therapeutically equivalent to other pharmaceutically equivalent products (first letter) and to provide additional information on the basis of FDA’s evaluations (second letter).

Order

A request for a product that will be used in the support of a single Patient care. Usually initiated by a Physician or an authorized person.

Order Check

A review of the Patient’s current and proposed drug therapy for the purpose of promoting therapeutic appropriateness. This includes evaluation of the medication order and information from the Patient record for known allergies, contraindications, reasonable dose, and route of administration, reasonable directions for use, duplication of therapy, drug-drug, drug-food, and drug-disease interactions, and adverse drug reactions.

Order Check Request

A request from VistA to PEPS to retrieve data from the COTS data source. This data will then be forwarded from PEPS back to VistA for use.

Order Set

A logical group of items ordered together for one Patient that can be acted on as one (i.e., signed, discontinued). It serves as a mechanism to allow order entry operations on related orders to occur as a single operation. An “order set” can be created manually and can be saved, stored, and retrieved as needed for common therapy treatments. It also includes functionality currently associated with complex orders, templates, and quick orders.

Order Unit Domain
