Medication errors are recognised as a major patient safety problem. 

They occur in all stages of the medication management process and have the potential to lead to patient harm, prolonged hospital stays, readmission or even death. Different measures to improve medication safety in hospitals have been taken to reach the World Health Organization’s (WHOs) target of globally reducing avoidable harm related to medications by 50%, by 2022. 

However, despite the introduction of computerised prescriber order entry solutions, electronic medication administration records, bar code medication administration, automated dispensing devices and other clinical decision support systems in some hospitals, medication errors continue to occur. In particular, in intensive cancer units and ambulatory care/one day hospitals where patients received anticancer medication every month they can significantly impact patient care and outcomes.
