Medication errors, which occur in the prescribing, dispensing, and administration of drugs, result in a high incidence of adverse events and significantly impact patient safety, with estimates of 44,000 to 98,000 deaths annually in the U.S. due to such errors. Factors contributing to medication errors include communication failures, workload issues, and improper training, and many errors go unreported due to perceptions of normalcy or lack of consequences. The Swiss cheese model illustrates how multiple safeguards can fail simultaneously, leading to patient risk, emphasizing the need for improved monitoring, team communication, and reporting systems to enhance safety.
