A patient was found unresponsive on a medical-surgical floor.

Barcode Medication Administration (BCMA) is a technology designed to reduce medication administration errors by ensuring the "five rights" of medication safety: right patient, right medication, right dose, right route, and right time.

In the scenario described, the administration of an unauthorized second dose of a sedating agent could have been prevented by BCMA. This system requires scanning both the patient's identification band and the medication barcode before administration. If the medication is not prescribed or if the timing is incorrect, the system alerts the healthcare provider, thereby preventing potential errors.

While other technologies like Automated Dispensing Machines (ADM), Radio Frequency Identification (RFID), and Computerized Provider Order Entry (CPOE) contribute to medication safety, BCMA specifically addresses errors at the point of administration, making it the most effective tool in this context.
