Study Finds Barcode Technology Reduces Medication Errors
- Categorized in: June 2010
WASHINGTON, DC—Using barcode technology with an electronic medication administration record (eMAR) substantially reduces transcription and medication administration errors, as well as potential drug-related adverse events, says a new study funded by HHS’ Agency for Healthcare Research and Quality (AHRQ). The study is published in the May 6 issue of the New England Journal of Medicine.
Barcode eMAR is a combination of technologies that ensures that the correct medication is administered in the correct dose at the correct time to the correct patient. When nurses use this combination of technologies, medication orders appear electronically in a patient’s chart after pharmacist approval. Alerts are sent to nurses electronically if a patient’s medication is overdue. Before administering medication, nurses are required to scan the bar codes on the patient’s wristband and then on the medication. If the two don’t match the approved medication order, or it is not time for the patient’s next dose, a warning is issued.
Researchers at Brigham and Women’s Hospital in Boston compared 6,723 medication administrations on hospital units before barcode eMAR was introduced with 7,318 medication administrations after barcode eMAR was introduced. Having barcode eMAR technologies in place was associated with reductions in errors related to the timing of medications, such as giving a medicine at the wrong time, and non-timing medication administration, such as giving a patient the wrong dose.
The researchers documented a 41% reduction in non-timing administration errors and a 51% reduction in potential drug-related adverse events associated with this type of error. Errors in the timing of medication administration, meaning a patient was given medication an hour or more off schedule, fell by 27%. No transcription errors or potential drug-related adverse events related to this type of error occurred.
“Medication errors in hospitals are a very serious issue and can often lead to patient harm,” said AHRQ Director Carolyn M Clancy, MD. “The good news from this study is that using barcode technology and an electronic medication administration record together can be an important intervention to help achieve medication safety.”
The findings have important implications because barcode eMAR technology is being considered as a 2013 criterion for meaningful use of health information technology under the American Recovery and Reinvestment Act of 2009.
