Medication errors are common in the hospital setting and can lead to adverse drug events.

The clinical impact of administration Error can be evaluated using the general classification of the American Society of Health-System Pharmacists and the National Coordinating Council for Medication Error Reporting and Prevention. Some administrative Error such as

1- Discrepancy occurs between the drug received by patients and the drug therapy intended by prescription. 

2- Error of omission

3- Deliberate violation of guidelines

  • Poor role model
  • Lack of available technology
  • Lack of knowledge of the prescription or administration procedures, and the complex design of equipment. 
  • Failure to check the patient's identity prior to administration. 
  • The wrong calculation to determine the correct dose.
