📌Introduction
Medication errors are among the most common preventable causes of patient harm in healthcare systems worldwide. These errors can occur at any stage of the medication-use process, including prescribing, dispensing, administering, and monitoring medications. Medication errors may result in adverse drug events, prolonged hospitalization, increased healthcare costs, and even death.
The World Health Organization (WHO) recognizes medication safety as a major public health concern and encourages healthcare professionals to implement strategies that minimize medication-related harm. Pharmacists play a crucial role in identifying, preventing, and reporting medication errors to improve patient safety.
This topic is highly important for pharmacy students, healthcare professionals, GPAT, DSSSB Pharmacist, and other competitive examinations.
🔍What is a Medication Error?
A medication error is any preventable event that may lead to inappropriate medication use or patient harm while the medication is under the control of healthcare professionals, patients, or consumers.
Medication errors can occur due to mistakes in prescribing, dispensing, administration, labeling, packaging, or monitoring of medicines.
