A nonprofit group called the Institute for Safe Medication Practices (ISMP) collaborates closely with healthcare professionals and institutions, regulatory bodies, trade associations, and the pharmaceutical industry to promote education regarding drug errors and their avoidance. Practitioners and patients who voluntarily report medication errors to the ISMP National Medication Errors Reporting Program (ISMP MERP) are subject to an impartial review by ISMP. Actual or probable errors that have been reported to ISMP are those that are displayed in the tables.
