Enhanced free-text search for aggregated medication error report analysis and risk detection.

Voluntary incident reporting data can provide unique insights into errors and opportunities to improve patient safety. This study used an enhanced free-text search method to identify the medication error (ME) reports involving substances commonly involved in medication errors (e.g., oxycodone, Warfarin). This approach increased the number of identified ME reports involving the specified medications and identified additional findings, such as inadequate pain management and duplicate prescriptions.
