Pitfalls of a Drug-Dispensing Audit Support System.

Dispensing audit support systems that authenticate pharmaceuticals via barcodes have been introduced into clinical practice to prevent dispensing errors, yet they occasionally generate false warnings, complicating clinical usage. This study sought to identify drugs prone to weight-error false warnings in the C-correct II® dispensing audit support system and to clarify its operational problems. We investigated the drugs that caused false weight-error warnings in the system, confirming that such errors did occur. Furthermore, the drugs causing weight errors tended to be significantly heavier than those that did not. Accurately identifying and addressing such operational issues within dispensing audit support systems will minimize the risk of dispensing errors and ultimately enhance medical safety.
