5 What is a medication error ? a medication error is any preventable event that may cause or lead to inappropriate medication use or patient harm while the medication is in the control of health professional, patient or consumer a medication error is any preventable event that may cause or lead to inappropriate medication use or patient harm while the medication is in the control of health professional, patient or consumer

6 Incidence of errors The precise incidence of medication errors in the NHS is unknown The precise incidence of medication errors in the NHS is unknown ~10-20% of all ADRs are due to errors ~10-20% of all ADRs are due to errors In USA 1.8% of hospital admissions have a harmful error leading to 7000 deaths per year In USA 1.8% of hospital admissions have a harmful error leading to 7000 deaths per year In Australia – 1% of all admissions suffer an ADR due to medication error In Australia – 1% of all admissions suffer an ADR due to medication error

7 Common error types? Wrong patient Wrong patient Contra-indicted medicine Contra-indicted medicine Wrong drug / ingredient Wrong drug / ingredient Wrong dose / freqency Wrong dose / freqency Wrong formulation Wrong formulation Wrong route of administration Wrong route of administration Poor handwriting on Rx Incorrect IV administration calculations or pump rates Poor record keeping Paediatric doses Poor administration techniques

30 Medicines Reconciliation: Definition Definition Definition Collecting an accurate list of the patient's home medicines, using that list to write prescriptions; and documenting changes or discontinuation of medicines and doses Collecting an accurate list of the patient's home medicines, using that list to write prescriptions; and documenting changes or discontinuation of medicines and doses NationalGuidanceNational Guidance National Institute for Health and Clinical Excellence: Patient Safety Guidance 1. Technical patient safety solutions for medicines reconciliation on admission of adults to hospital.

31 Medicines Reconciliation: Process 1. Verification: Collection of the medication history Obtaining a complete and accurate list of each patient's current medications (medication history) including name, dosage, frequency and route Obtaining a complete and accurate list of each patient's current medications (medication history) including name, dosage, frequency and route 2. Clarification : Ensuring that the medications and doses are appropriate Comparing the in-patient prescription or TTA to the medication history Comparing the in-patient prescription or TTA to the medication history 3. Reconciliation : Documentation of changes in the prescriptions Resolving any discrepancies that may exist between the medication history list and prescribed medicines before an adverse drug event (ADE) can occur Resolving any discrepancies that may exist between the medication history list and prescribed medicines before an adverse drug event (ADE) can occur Note: ADEs can result from omitted drugs or doses Note: ADEs can result from omitted drugs or doses This is done at admission, on transfer between levels of care, on discharge This is done at admission, on transfer between levels of care, on discharge

32 If we dont reconcile medication?
