A quality professional noted that the medication error rate in a specialty clinic has been steadily increasing over the past 4 months and was now above the acceptable threshold. The clinic used a bar coding system that required the medication to be scanned prior to administration. When this occurred, pop-up screens on the computer asked the clinician a series of questions intended to ensure the correct medication and dose was being given to the correct patient. The equipment and medications used were the same, and the bar coding system had been in place for 14 months.
Which of the following is most likely to be the root cause of the increased medication errors?
