Medication errors related to computerized provider order entry systems in hospitals and how they change over time: a narrative review.

Computerized provider order entry (CPOE) systems have been advocated as a strategy to reduce medical errors, but some errors persist. This narrative review identified knowledge gaps in the relationship between CPOE systems and how systems-related errors change over time. Studies suggest that system-related errors persist with long-term use of CPOE systems, but future research should explore the types of errors that occur, when they occur, and the system factors contributing to the errors.
