Purpose:
Records from USP's MEDMARX database of medication errors for 2002 were studied.
Methods:
Records of medication errors submitted to MEDMARX by participating health care institutions during 2002 were analyzed for error category index (whether a medication error actually occurred, whether it reached the patient, and, if so, the effect), node (the point in the medication-use process where the error occurred), type of error, cause, contributing factors, and drug products involved.
Results:
The number of participating institutions was 482, and the number of medication error records released to MEDMARX was 192,477, an 82.2% increase from 2001. Errors that did not reach the patient were seen in 35% of the records, errors that reached the patient were seen in 49%, and errors that may have contributed to or resulted in harm were seen in 2%. The nodes, types of errors, causes of errors, contributing factors, and leading products by generic name are discussed.
Conclusion:
An analysis of over 192,000 records of medication errors submitted by nearly 500 health care facilities to USP's MEDMARX database in 2002 produced detailed information on the scope and nature of medication errors.
Insights
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.
- Examination of error nodes, types, causes, contributing factors, and drug products.
Main Results:
- A total of 192,477 medication error records were analyzed from 482 institutions, an 82.2% increase from 2001.
- 35% of errors did not reach the patient, 49% reached the patient, and 2% caused or may have caused harm.
- Detailed findings on error nodes, types, causes, contributing factors, and drug products are presented.
Conclusions:
- Analysis of over 192,000 medication error records provided comprehensive data on medication errors in 2002.
- The findings offer valuable insights into the medication use process and potential areas for intervention.
- This study underscores the importance of robust medication error reporting systems for enhancing patient safety.

Pharmacovigilance
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
