WHAT IS A MEDICATION ERROR?
• Medication error: • Any preventable event that may cause or lead to
inappropriate medication use or patient harm while the medication is in the control of:
• Health care professional
• Patient
• Consumer
2016 ANNUALMEETING
WHAT IS A MEDICATION ERROR?
• Medication error: • May be related to professional practice, health care
products, procedures, and systems
• May include • Prescribing• Order communication• Product labeling• Packaging and nomenclature• Compounding• Dispensing• Distribution• Administration• Education• Monitoring• Use
2016 ANNUALMEETING
A medication error is “any error occurring in the medication use process.”(Bates DW, Boyle DL, Vander Vliet MB, Schneider J, Leape L. 1995. Relationship between medication errors and adverse drug events. Journal of General Internal Medicine 10(4): 100–205.)
MEDICATION USE PROCESS• SODAM
• Selection• Ordering• Dispensing• Administering• Monitoring
• Errors can occur at any point in the Medication Use Process
• They occur most frequently in the Ordering (56%) and Administration (34%) phase JAMA.1995; 274:29-34

NCC MERP INDEX FOR CATEGORIZING MEDICATION ERRORS
• Category H• An error occurred that required
intervention necessary to sustain life
2016 ANNUALMEETING
DEFINITIONS
• Adverse Drug Event (ADE): An injury resulting from medical intervention related to a drug
• Source: Institute of Medicine (IOM)
• Adverse Drug Reaction (ADR): Any response to a drug which is:• noxious and unintended
• occurs at doses normally used in man for prophylaxis, diagnosis, or therapy of disease, or for the modifications of physiological function• Source: World Health Organization (WHO)
2016 ANNUALMEETING
NCC MERP Fact Sheet 2015-02 v91
DEFINITIONS• “Preventable ADE”: harm caused by the use of a
drug as a result of an error• Patient given a normal dose of drug but the drug was
contraindicated in this patient
• These events warrant examination by the provider to determine why it happened
• “Non-Preventable ADE”: drug-induced harm occurring with appropriate use of medication • Anaphylaxis from penicillin in a patient with no previous
history of an allergic reaction
• While these are currently non-preventable, future studies may reveal ways in which they can be prevented

QUALITY IMPROVEMENT PROCESSES
• The way to prevent errors is to redesign the systems and processes that lead to errors rather than focus on correcting the individuals who make errors
• Effective strategies for reducing errors include making it difficult for staff to make an error and promoting the detection and correction of errors before they reach a patient and cause harm

NATIONAL PATIENT SAFETY GOALS
• Identify patients correctly• NPSG.01.01.01: Use at least two
ways to identify patients • For example, use the patient’s name and
date of birth
• This is done to make sure that each patient gets the correct medicine and treatment
2016 ANNUALMEETING
http://www.jointcommission.org/standards_information/npsgs.aspx Accessed 3/12/15
NATIONAL PATIENT SAFETY GOALS
• Use medicines safely• NPSG.03.05.01: Take extra care with patients who
take medicines to thin their blood
• NPSG.03.06.01: Record and pass along correct information about a patient’s medicines • Find out what medicines the patient is taking
• Compare those medicines to new medicines given to the patient
• Make sure the patient knows which medicines to take when they are at home
• Tell the patient it is important to bring their up-to-date list of medicines every time they visit a doctor
2016 ANNUALMEETING
http://www.jointcommission.org/standards_information/npsgs.aspx Accessed 3/12/15
AHRQ PATIENT SAFETY TIPS
• Re-engineer hospital discharges• Reduce potentially preventable readmissions by:
• Assigning a staff member to reconcile medications• Schedule necessary follow-up medical appointments
• Create a simple, easy-to-understand discharge plan for each patient that contains:• A medication schedule• A record of all upcoming medical appointments• Names and phone numbers of whom to call if a problem
arises
• AHRQ-funded research shows that taking these steps can help reduce potentially preventable readmissions by 30 percent
2016 ANNUALMEETING
http://www.ahrq.gov/patients-consumers/diagnosis-treatment/hospitals-clinics/10-tips/index.html
AHRQ PATIENT SAFETY TIPS
• Educate patients about using blood thinners safely • Patients who have had surgery often leave the hospital
with a new prescription for a blood thinner
• If used incorrectly, blood thinners: • Can cause uncontrollable bleeding • Are among the top causes of adverse drug events
• A free 10-minute patient education video and companion 24-page booklet, both in English and Spanish, help patients understand what to expect when taking these medicines

HIGH ALERT MEDICATIONS
2016 ANNUALMEETING
HIGH ALERT MEDICATIONS
• High-alert medications are drugs that bear a heightened risk of causing significant patient harm when they are used in error
• Although mistakes may or may not be more common with these drugs, the consequences of an error are clearly more devastating to patients

Classes
• Insulins
• Opiates/ Narcotics
• Cancer Chemotherapy
• Oral hypoglycemics
• Anticoagulants
Medications
• Warfarin
• U-500 insulin
HIGH ALERT MEDICATIONS - STRATEGIES• Improving access to information about these drugs
• Limiting access to high-alert medications
• Using auxiliary labels
• Using automated alerts
• Standardizing the ordering, storage, preparation, and administration of these products
• Employing redundancies
• Automated or independent double-checks when necessary
• Note: manual independent double-checks are not always the optimal error-reduction strategy and may not be practical for all of the medications on the list
• Providing mandatory patient education

ERROR IN MEDICINE
• Much of mental functioning is automatic, rapid and effortless
– Leape, L.L.
2016 ANNUALMEETING
INATTENTIONAL BLINDNESS• Brain has limited resources when it comes to
attentiveness
• Our senses receive much more information than can possibly be processed at one time
• The brain allows a lot of information in, peeling off just a few pieces of selected information for a closer look
• The brain fills in the gaps
• Accidents happen when attention mistakenly filters away important information and the brain fills in the gaps with incorrect information
2016 ANNUALMEETING
INATTENTIONAL BLINDNESS
• More likely to occur if attention is diverted to secondary tasks• More complicated tasks require our full
attention
• Low workload, Carrying out highly practiced tasks• Boredom and decreased mental attention
• Expectation – Confirmation Bias

JUST CULTUREAn evolution from Punitive to No Blame to Just Culture
• Punitive: work carefully, counseling, discipline, procedural violations unacceptable
• Blame Free: response to shortcomings of a punitive culture, workers who made honest errors were not truly blameworthy
• Just Culture: emphasis on learning and shared accountability, workers continually look for risk and are thoughtful about behavioral choices, managers look for system design features that are reliable
2016 ANNUALMEETING
JUST CULTURE
• Good system design + good behavioral choices of staff = good results
• Accountability is not dependent on outcome but behavioral choices under worker’s control
• Shared accountability
• Four areas of focus: • learning/reporting culture• open/fair culture• design of safe systems• management of behavioral choices
2016 ANNUALMEETING
BEHAVIORS
• Human error: inadvertent action; inadvertently doing other than what should have been done; slip, lapse, mistake
• At-risk behavior: behavioral choice that increases risk where risk is not recognized, or is mistakenly believed to be justified
• Reckless behavior: behavioral choice to consciously disregard a substantial and unjustifiable risk
