Iatrogenic Medication Errors Among Older Adults Reported to a Poison Center Network.

Iatrogenic medication errors in older adults occur across care settings and are most often managed in the ED. While many cause minor harm, a subset results in serious outcomes, with ED-based errors posing higher risk. These findings underscore the need for targeted interventions, particularly during administration and for cardiovascular agents, and provide data to guide strategies and future research to protect this vulnerable population.
