Medication Errors in Children Ian Chi Kei Wong Head and Professor - PowerPoint PPT Presentation

Medication Errors in Children Ian Chi Kei Wong Head and Professor Centre for Safe Medication Practice and Research Department of Pharmacology and Pharmacy University of Hong Kong Global Research in Paediatrics – Network of Excellence (GRiP) “A cheerful heart is good medicine, but a crushed spirit dries up the bones. (Proverbs 17:22)”.

Learning outcomes • At the end of the session, you will be able to: – Explain why children are at greater risk of medication errors. – Describe epidemiology and nature of medication error in children. – Five risks

Literature review

Literature review • Great variation in the paediatric medication error rates reported due to differences in study design. – prescribing error rate 0.45 to 30.1 errors per 100 orders in the USA – drug administration error rates varied from 0.6% to 27% • Dosing errors are the most common type of errors in paediatrics (particularly 10-fold or greater overdose caused by calculation errors).

How big is the problem in our hospital?

Why children may be at greater risk from medication errors • Drug doses are calculated based on a patient’s age, weight or body surface area. • Weight changes over time & recalculation of drug doses is required, particularly in neonates. • Inadequate information. • Inadequate availability of appropriate dosage forms and concentrations. • Fewer internal reserves to buffer any medication errors which may occur.

Be aware • Mistakes can happen at any stage. • Everyone in the healthcare team can make a mistake. • Including you!

When you make a mistake, admit it, correct it, and learn from it - immediately . Stephen Covey

Summary of High Risk 1) High risk paediatric groups Neonatal, learning difficulty and oncology 2) High risk drug groups Analgesics, anticonvulsants, any high potent drugs 3) High risk pharmaceutical formulations Adult formulations for paediatric use, IV, Unlicensed products 4) High risk healthcare workers Unqualified, Inexperienced, Newly appointed and Tired 5) High risk changing care settings Admission and discharge
