Report a Medication Error

The ISMP National Medication Errors Reporting Program (ISMP MERP) is an internationally recognized program for healthcare professionals to share potential or actual medication errors that occurred at their workplace. Reporting an error or hazardous condition is simple and confidential.

How to Report a Medication Error

We ask that you provide as much detail in your report as possible so that our experts can identify and characterize the likely causes and contributing factors. Specifically, include the following:

  • The details of what went wrong or could go wrong
  • The causes and contributing factors of the event  
  • How the event or condition was discovered or intercepted
  • The actual or potential outcome of the involved patient(s)
  • Your recommendations for error prevention
  • Product names, dosage forms, and dose/strength. For product-specific concerns (e.g., labeling and packaging risks), please include the manufacturer
  • Specific information regarding the model, build, and manufacturer of involved healthcare information technology and medication-related devices
  • Any associated materials that help support the report being submitted (e.g., images of devices, display screens, products, containers, labels, de-identified prescription orders)

After you submit your confidential report, ISMP staff will follow up with you to ask additional questions to clarify what went wrong and to identify the causes and factors that contributed to the reported event.

Report to ISMP as a Patient Safety Organization

YAHRQ PSO logoou may prefer to report an adverse medication event to ISMP as a federally certified Patient Safety Organization (PSO). As a PSO, federal legal protection can be provided for certain patient safety information prepared within your patient safety evaluation system and submitted to ISMP. The protected information, called patient safety work product, includes information you provide about why the error happened or why the hazard exists, along with any further analysis of the event provided back to you by ISMP. The basic facts, whether written or observed, regarding what happened along with the patient’s medical/health records, are NOT considered patient safety work product and cannot be provided with federal protection in the event of a lawsuit. However, contextually identifiable information will NOT be disclosed outside ISMP unless we are legally compelled to do so.
