STRATEGIC PLAN TO MINIMIZE MEDICATION ERRORByMr.Jawed Ali Quazi
Our goals for todayDefine medication errors and classify their significanceUnderstand the extent of medication errors and their impact on patient careDiscuss the many factors that contribute to errors and the impulse to place blame on healthcare workersExamine approaches to minimize the risk of medication errors
Defining medication errors"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 the health care professional, patient, or consumer. Such events may be related to:
National Coordinating Committee-Medication Error Reporting and Prevention (NCC MERP); accessed at http://www.nccmerp.org/aboutMedErrors.html; Jan. 2012. professional practice health care products procedures and systems product labeling, packaging, and nomenclature
dispensing distribution administration education monitoring
found 616 medication errors (5.7%), 115 potential ADEs (1.1%), and 26 ADEs (0.24%). Of the 26 ADEs, 5 (19%) were preventable. Most potential ADEs occurred at the stage of drug ordering (79%) The rate of potential ADEs was significantly higher in neonates in the neonatal intensive care unit.

Types of Medical Errors
Non-Surgical Errors 52.3%
Some reasons errors occur
poor communications within healthcare team verbal orders poor handwriting improper drug selection missing medication incorrect scheduling look alike / sound alike drugs polypharmacy availability of floor stock (no second check) drug interactions hectic work environment lack of computer decision support
Causes of Medication ErrorsCalculation errorsImproper use of zeros & decimal pointsInappropriate use of abbreviationsCareless prescribing Illegible handwritingMissing informationDrug product characteristicsCompounding /drug preparation errorsPrescription labelingWork environment & personnel issuesDeficiencies in medication use systems

Pregabalin (Lyrica)An anticonvulsant approved in Canada and the US since2005 to treat neuropathic pain approved by the European Commission in 2006 to treat generalized anxiety disorder. The maximum dose of pregabalin depends on its indication but should not exceed 600 mg/day.
Pregabalin (Lyrica)Clinical studies including 5500 patients showed that euphoric effects were reported more frequently in pregabalin groups versus placebo (4% vs. 1%, respectively).A clinical abuse liability study found that pregabalin had a potential for euphorigenic activity in susceptible populations.Therefore scheduled by the US Drug Enforcement Administration under the Controlled Substances Act as a Schedule V drug, indicating that it had abuse potential.

ROOT CAUSE ANALYSISNo Medical Reconciliation
Computer Operated Entry
Hospital File Number
Medical ReconciliationReconciliation: A process of identifying the most accurate list of all medications a patient is takingincluding name, dosage, frequency, and route.Requires comparing the patients list of current medications against the physicians admission, transfer, and/or discharge ordersNeeds even for OPD patients by MOHhttp://www.ihi.org/NR/rdonlyres/598D427A-4BDA-419D-91B5-B836D23A6F1D/0/CampaignOverview101105.ppt#358,9,Prevent Adverse Drug Events by Implementing Medication Reconciliation

Sources of ErrorPrescribing error - selecting the wrong or inappropriate drug/dose/formulation/duration etcCommunicating those instructionsSupply error - timely; wrong drug, dose, route; expired medicines, labelling.Administration error - timing; wrong route; wrong rate/technique.Lack of user education - actions to take.

Illegible HandwritingHandwriting of physicians is subject of jokesno laughing matter Unclear orders should be clarified Use standardized, preprinted order forms Computer generated & typewritten labelsUse of upper- and lowercase lettering (TALLman)
Missing InformationLack of medical information about patient may cause errorage weight allergies diagnosisindication & severity of condition
Human Error(Mistakes, Slips, Lapses)Error is inevitable due to our limitations:limited memory capacitylimited mental processing capacitynegative effects of fatigue other stressorsWe all make errors all the timePatients suffer adverse events much more often than previously realisedErrors often NOT immediately observed
Safe Medication Practice Unit48So these people your predecessors PERCEIVED that they wouldnt have any problems. Doctors dont go out there, thinking that they will make mistakes.
These are some of the reasons why(points on slide - just need to raise awareness!)
ConclusionsHuman beings will always make errorsErrors are common in medicine, killing tens of thousandsNaming, blaming and shaming have no remedial value
