In 2002, over 192,000 medication errors were reported to the MEDMARX database. Most errors did not reach patients, but 2% caused harm, highlighting the need for improved medication safety.

Area of Science:

Pharmacovigilance
Patient Safety
Health Informatics

Background:

Medication errors pose a significant threat to patient safety.
The MEDMARX database collects medication error data from healthcare institutions.
Understanding medication error trends is crucial for developing effective prevention strategies.

Purpose of the Study:

To analyze medication error data from USP's MEDMARX database for the year 2002.
To identify the scope, nature, and contributing factors of medication errors.
To provide insights into medication error categories, nodes, causes, and involved drug products.

Main Methods:

Analysis of 192,477 medication error records submitted to MEDMARX in 2002.
Categorization of errors based on occurrence, patient reach, and effect.
