When a GP prescribes patients with certain medications, most patients will then go on to visit a pharmacy to collect their medication. On rare occasions, patients may be given the wrong medication due to pharmacy errors, also known as medication errors, these can have serious, long lasting consequences for patients. In this article, we will be discussing the statistics surrounding medication errors in the UK. 


Medication errors 

According to the NHS, “Medication errors are any Patient Safety Incidents (PSI) where there has been an error in the process of prescribing, preparing, dispensing, and administering, monitoring or providing advice on medicines.” Medication errors can happen in pharmacies and can potentially cause patients to have negative health implications. Some medication errors can be minor and cause no significant harm to patients, whereas severe medication errors can lead to adverse consequences for patients and potentially even death. Medication errors can include: 

  • Incorrect mixing of prescription medication 
  • Dispensing the wrong prescription 
  • Dispensing the wrong dose of medication 
  • Incorrect labelling of a prescription 
  • Vaccination error – where a vaccination has been given in the incorrect site of the arm 

According to BMJ, there are more than 237 million medication errors made every year in England and this costs the NHS upwards of £98 million and more than 1700 lives every year. The harm that is caused by medication errors has been recognised as a ‘global issue’ and the World Health Organization (WHO) aims to halve the level of avoidable harm that is associated with medication error. 

The NHS Patient Safety Strategy also has a focus on medication errors, this programme aims to reduce severe avoidable medication-related harm by 50% by March 2024.
