Ensuring patient safety is a fundamental tenet of quality healthcare. Medication errors represent a significant challenge within the healthcare system, with the potential to cause considerable harm. Understanding the principles of patient safety, the nature and causes of medication errors, and employing systematic approaches like Root Cause Analysis (RCA) to learn from errors are crucial skills for all healthcare professionals.
