The main types of medication incidents reported were:

• 'Wrong drug/medicine' supplied (31%)

The most important factor for reported errors was found to be:

• 'Medicines with a similar looking or sounding name' (61%)
• 'Work and environment' factor was cited as the main contributing factor for the reported errors (61%)
• The majority of reported errors (86%) involved either a near miss (30%) or an error causing no harm to the patient (56%)

• Allopurinol/atenolol

Tips for minimising risk/general action points:

• Add a note on the PMR system highlighting an unusual form or strength of a medicine received regularly by a patient, especially if an error has occurred previously
• Ensure robust date checking procedures are being implemented and check dates of all medicines as they are dispensed, including those just received from the wholesaler
• Keep all surfaces clear of clutter
• Separate products with similar names on dispensary shelves
• Consider using brightly coloured shelf edge labels
• Take a mental break when dispensing/checking prescriptions
• Take extra care when checking prescriptions dispensed by inexperienced/trainee staff
• Ensure that split packs are clearly marked and, when dispensing, check the contents to ensure the correct item is in the pack
• For insulin, show the box to the patient before handing over

The NPA has published €Dispensing process: best practice€ to provide guidance for pharmacists/ pharmacy owners when reviewing dispensing SOPs.
