Computerized provider order entry (CPOE) systems are widely used and can help prevent medication administration errors. This mixed-methods study examined the impact of CPOE on medication safety in the pediatric department at one Canadian hospital. Researchers found that most errors occurred during the medication administration step rather than the prescribing step. The researchers also observed a non-statistically significant decrease in medication errors overall, which was primarily attributed to significant improvements in errors during order acknowledgement, transmission, and transcription.
