QuarterlyActionAgenda
One of the most important ways to prevent medication errors is to learn about problems that have
occurred in other organizations and use that information to prevent similar problems at your practice
site. To promote such a process, the following selected agenda items have been prepared for your senior
leaders and an interdisciplinary committee to stimulate discussion and action to reduce the risk of medication
errors. These agenda items appeared in the ISMP Medication Safety Alert! between April and June 2008. Each
item includes a brief description of the medication safety problem, recommendations to reduce the risk of
errors, and the issue number in parentheses to locate additional information as desired. Look for our highalert medication icon under the issue number if the agenda item involves one or more medications on the ISMP
List of High-Alert Medications. Many product-related problems can be viewed in the ISMP Medication Safety
Alert! section of our website. The Action Agenda is also available for download in a Word format
(www.ismp.org/Newsletters/acutecare/articles/ActionAgenda0803.doc) that allows expansion of the columns in the
table designated for organizational documentation of an assessment, actions required, and assignments for each
agenda item. Continuing education credit is available for nurses at:
