Based on the chart, which shows that administering errors are themost frequent type of medication error, implementing a barcode medication system would likely have the greatest impact on reducing adverse events. Barcode systems help ensure that the right patient receives the right medication at the right dose and time by requiring a scan of both the patient’s ID and the medication barcode before administration. This technology directly addresses the stage where most errors occur, thereby reducing the likelihood of administering errors.

Computerized physician order entry (A): This system would primarily reduce ordering errors, which are less frequent than administering errors in this data.

Automated medication cabinets (C): These help with dispensing errors, but these errors are less frequent than administering errors.

Clinical decision support tools (D): These tools help reduce evaluation and ordering errors but do not directly address the high rate of administering errors.
