Prevalence of medication administration errors in two medical units with automated prescription and dispensing.
Rodriguez-Gonzalez CG, Herranz-Alonso A, Martin-Barbero ML, et al. J Am Med Inform Assoc. 2012;19:72-78.
Technological solutions such as computerized provider order entry (CPOE) hold promise for reducing medication errors at the prescribing and dispensing stage, but patients may still be harmed by incorrect administration of medications, which have been shown to be disturbingly common in prior studies. Conducted at an academic hospital in Spain that had an established CPOE system, this study found an overall administration error rate of 22%, consistent with prior studies. The hospital in question did not have a barcoding medication administration system. Combining barcoding with CPOE in a closed-loop system has been shown to significantly reduce the overall medication error rate.

Addition of electronic prescription transmission to computerized prescriber order entry: effect on dispensing errors in community pharmacies.
Moniz TT, Seger AC, Keohane CA, Seger DL, Bates DW, Rothschild JM. Am J Health Syst Pharm. 2011;68:158-163.
Dispensing errors in the community setting are a frequent source of concern despite greater adoption of computerized prescriber order entry (CPOE) and barcode technologies. This study added e-prescribing technology to an existing CPOE system and evaluated discrepancies between prescribers' orders and the dispensed prescription information. Investigators captured more than 11,000 prescriptions written in the control clinics and nearly 30,000 in the e-prescribing ones to compare rates before and after implementation. E-prescribing was associated with a statistically significant reduction in dispensing errors, by nearly half, compared with printing a prescription out of a CPOE system and then handing it to patients. The authors advocate for this feature as a meaningful intervention to improve medication safety. A past AHRQ WebM&M commentary discussed a dispensing error that originated from a poorly handwritten prescription.

Bar Coding for Medication Safety, September 2008
Eric G. Poon, MD, MPH, is Director of Clinical Informatics at Brigham and Women’s Hospital and Assistant Professor of Medicine at Harvard Medical School. Dr. Poon’s research has focused on using health information technology to improve patient safety. He oversees the development and implementation of clinical applications including computerized physician order entry (CPOE) and barcode-assisted electronic medication administration record, and was lead author on the first rigorous study demonstrating the impact of a bar coding system in a hospital pharmacy. We asked him to speak with us about how such technology can augment medication safety.
