Top electronic medication administration record software vendors

Electronic medication administration records (eMARs) are a part of a patient’s electronic health record (EHR) that keeps track of when medications are given to the patient during a hospital stay.

The application supports the five rights of medication administration, which exist to ensure that the right medicine is given to the right patient, in the right dose, via the right route (for example oral or intravenous), and at the right time. In a hospital, the medication administration process usually involves barcoding, helping the nurse verify the patient, confirm the drug, and accurately document the time it was taken.

eMAR systems are usually modules of EHRs allowing data to be shared or flow between computerized practitioner order entry systems (CPOEs), medical devices such as infusion pumps, automated pharmacy devices, and nursing charting systems.

Using hospital technology implementation data from the Definitive Healthcare HospitalView product, we reviewed the top eMAR vendors installed at U.S. hospitals.
