patient.
MEDICATION
ERRORS
Medication Errors: Introduction
 As many as 98,000 people die in any given year from medical errors that occur
in hospitals.
 That's more than die from motor vehicle accidents, breast cancer, or AIDS.
 Indeed, more people die annually from medication errors than from workplace
injuries.
 The seriousness of medication error came to be known when
Institute of Medicine (US) stated in, “To Err is Human; Building a
Safer Health System,” that around 44,000 to 98,000 deaths in
America occurred as a result of medical errors.
 The impact of medication error on patient's well-being is
unfathomable.
Most of the medication errors do not cause any harm to the patient, but
there are some that cause unwarranted results, including
 temporary or permanent harm to the patient's health and well-being
 increased length of hospitalization
 increase in cost of treatment
 people losing faith in healthcare delivery system
 and even deaths
 A great need to break the silence that has surrounds medical errors and
their consequence.
Why these
mistakes
happen?
"How can we
learn from our
mistakes?"
How we define an error?
 The word ERROR has drawn attention to "prevention"
 According to Webster's New Collegiate Dictionary :
E.g. One can make An error of omission (failure to act correctly) Or An error of
commission (acted incorrectly)
Error is "an act that through ignorance, deficiency, or accident departs from or fails
to achieve what should be done is generally known as "the five rights": the right
Drug, right Dose, right Route, right Time, and right Patient.

What is medication error?
Medication error
An error in the prescribing, dispensing,
administration of a drug irrespective of whether
such errors lead to adverse consequences or not.
What is medication error?
 The National Coordinating Council for Medication Error Reporting and Prevention
(NCCMERP) has defined medication error as
Thus, any medication error can be prevented before it may or may not cause harm to the
patient.
“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. These events may be related to professional practice, healthcare products,
procedures, and systems, including prescribing, order communication, product labeling,
packaging and nomenclature, compounding, dispensing, distribution, administration,
education, monitoring, and use”.1
Medication error in
developed countries
is of PRIMARY
CONCERN
Medication Error is
just a TERM and its
significance is
undervalued.
Developed Countries Vs Developing
Countries
Medication error: Underreported
 Medication errors are routinely encountered but remain
underreported.
 Reporting is important to thoroughly examine their contributing
factors and to implement preventive actions so as to avoid them
in future from happening.
Medication error: why Underreported ?
 Perception 1: it may be considered to be no one's fault (Haw, Stubbs, &
Dickens, 2014) or part of normal practice (Soydemir et al., 2016).
For instance, the standard time for administration of a once-a-day medication
may be 8:00 a.m. at a particular institution. A nurse administers a patient's
morning medications at 2:00 p.m. because the patient was away from the unit
for a procedure. No medical order indicated medications should be withheld
until after the procedure. Having a seemingly valid excuse for late
administration of the medication does not make this any less a medication
error. This error may go unreported because it is seen as a normal part of care.
Medication error: why Underreported
 Perception 2: An error does not need to be reported if it does not
seem to cause harm. Nurses typically do not report near misses or
errors if there are no serious consequences (Hashemi, Nasrabadi,
& Asghari, 2012; Kim et al., 2014; Wagner, Damianakis, Pho, &
Tourangeay, 2013).
In the above example, the nurse may believe no harm was done because the
patient did not develop any obvious complications and so may not report
this late administration as an error.
Medication error: why Underreported
 Perception 3: Lack of a reporting system at an institution or lack
of staff awareness that a system for reporting exists (Lederman,
Dreyfus, Matchan, Knott, & Milton, 2013; Soydemir et al., 2016).
 Perception 4: Fear of consequences if a medical error is reported
(Almutary, & Lewis, 2012; Haw et al., 2014; Kagan & Barnoy, 2013; Yung, Yu,
Chu, Hou, & Tand, 2016).
Need to be reported
 The Institute of Medicine supported the concept of a culture of
safety to encourage error reporting without fear of repercussion or
blame
Reason:
So that root cause of errors could be identified and prevention
measures instituted (Kohn et al., 2000).

Incidence
Incidence of medication Errors
 Interesting but horrifying facts:
 More people in USA die in a given year as a result of medical
errors than from motor vehicle accidents , cancers or AIDS
 Majority are medication errors
 Indian study of paediatric intensive care unit reported 68.5% of
all errors were medication errors
Incidence
 Reported incidence of this iatrogenic disease related to medication error-
tip of the iceberg
 Difficult to determine
 Few studies provide complete evaluation of errors
 Different methods to detect errors
 Various definitions of errors
 Large volumes of medication dispensed
 Annual prescriptions approx. 3.54 billion
 Small % of 3.54 billion is still large number
Indian Scenario
 Prof Jha reported 5.2 million medical errors take place in India annually.
 The British Medical Journal quoted that India, like any other developing country,
is witnessing a lot of medical errors.
 The main reason being that we do not have trained doctors and nurses to
measure the clinical outcomes.
Incidence
 Harvard medical practice study found 19% of adverse event in
hospitalized patients R/T drug complications
 Error rates in outpatient pharmacies reported ~12% and in-hospital
~1 error per patient per day
 19% of all doses were not administered correctly
 43% of errors were due to wrong time of administration
 ~1.5 million people are harmed by medications each year
 Up to 400,000 of adverse events considered preventable
 Medication error studies reported different rates (underreported,
different tools used)
 Errors before medications reaching patient are not reported.
Causes of Medication Errors
Swiss Cheese Model
 Need to identify and address the root causes of medication errors
 Can be done through continuous quality improvement (CQI).
 Medication error has multiple causes—a series of mistakes, oversights
or system failures that combine to create risk for a patient.
 This type of medication error can be visualized with the SWISS CHEESE
MODEL OF SYSTEM accidents
Swiss cheese Model
What is Swiss Cheese Model?
 Pictorial model for medication errors
 Several slices of Swiss cheese, each represent a different layer of prescriber,
pharmacist, nurse & patient related defenses or safeguards
 Each layer has holes that reflect the inherent weaknesses in that particular
safeguard.
 Normally, if one hole is penetrated, another slice (or safeguard) stops an error in its
tracks.
But what if the holes suddenly lined up? Now it’s as though there are no safeguards at all.
Swiss Cheese Model
Medication error : As per Occurrence
 Near Miss:
 A Near-miss is an unplanned event that did not result in injury, illness,
or damage but had that the potential to do so.
 Did not result in patient harm, but could be categorized as near-miss
 Medication incident/ Sentinal event:
 An unexpected incident, related to system or process deficiencies, which
leads to death or major and enduring loss of function for a recipient of
healthcare services
Types of Medication Errors
 Prescribing Errors (39%)
 Transcription errors (12%)
 Dispensing Errors (11%)
 Administration errors (38%)
Causes of Medication Errors
 Calculation errors
 Overload
 Shortage of staff
 Illegible Handwriting
 Misinterpretation of Prescription
 Human Errors
 Inappropriate use of Abbreviations
 Oral/Verbal orders
 Look alike Sound alike drugs
 Wrong dosage calculation
 Improper use of zeroes and decimals
 Careless prescription
 Missing information
 Drug Product characteristics
 Drug preparation errors
 Prescription labeling
 Work environment & personnel issues
 Lack of concentration
 Double check not possible
1. Calculation errors
 Made by
 Prescribers
 Pharmacists
 Technicians
 Nurses
 Pediatric population at risk- adult formulations be diluted/manipulated for peds
 Personnel with multiple years of experience are just as likely to make
mathematical errors as inexperienced
2. Decimal Points & Zeroes
3. Dangerous abbreviations
4. High Alert medication errors
Only written
orders
accepted
To be
checked for
adverse
reactions
5. Prescribing errors
 A clinically meaningful prescribing error occurs when, as a result of prescribing decision or
prescription writing process, there is an unintentional significant reduction in the treatment
being timely and effective and Increase in the risk of harm when compared with generally
accepted practice
It includes
 Incorrect prescription #Missing information
 Illegible handwriting # Use of apothecary system
 Drug allergy not identified #Confusion regarding concentration of products
 Irrational combinations
 Out of list abbreviations
 Verbal orders
Risk factors of prescribing errors
 Work environment
 Workload
 Communication gap within team
 Physical and mental well being
 Lack of knowledge
 Organizational factors(inadequate training)
 Low perceived importance of prescribing
 An absence of self awareness
6. Wrong drug & wrong route
 Drug-drug interaction
Warfarin prescribed to patient already on salicylate
 Duplicative therapy
Atenolol ordered for patient already taking metoprolol
 No indication
Cetrizine ordered for patient with fever
 Wrong route
Order of betamethazone acetate suspension ordered to be given intravenously
7.Dispensing error
 Any unintended deviation among the dispensed drugs on comparison with the
written medical prescription or medication order is defined as dispensing error.
 The range of dispensing errors even widens in the global scenario from 0.015 to
33.5%;
 4 errors per day per 250 prescriptions filled
 Over 51 million dispensing errors per year
Most prevalent dispensing errors
 Similar names and packaging of drugs (look alike Sound alike)
 Wrong dose, wrong drug, or wrong patient
 Dispensing incorrect medication, dosage, strength or dosage form
 Failure to identify drug interations or contraindications
 Dosage miscalculations
 Illegible handwriting,
 Negligence by the pharmacists
 Other: Judgmental errors, increased workload, lack of supporting staff, frequent
interruptions, and inadequate time to label the drugs and counsel the patients.
8.Look alike Sound alike drugs
 LASA drugs are medications that look or
sound similar to each other, either by their
generic name, or brand name.
 They might have similar packaging, similar-
sounding names, or similar spellings.
Example of dispensing error
8.Illegible handwriting
 The jokes about physicians and their sloppy handwriting are age-old.
 But for some people it is not funny at all.
 A misread prescription can lead to mistreatment and cause death.
 Causes both prescription error and dispensing error
 7,000 deaths annually are attributable to sloppy handwriting.
 Recently in a programme on BBC : concluded that in Tamil Nadu, only
one in five doctors in rural areas writes legible prescriptions
9.Verbal and telephone orders
Errors of omission & Commission
10.Drug concentration
 Failure to include concentration in prescription can result in wrong
dose being dispensed
 E.g.
•Amoxicillin suspension half tsp (2.5ml) TID
•Concentration??
1 amp or 1 vial or 1 cap UNCLEAR
Order for one vial of magnesium sulphate
•2ml vial (8mEq)
•20 ml vial (16mEq)
•10 ml vial of 50% concentration (40mEq)
11.Missing information
13. Communication failure
 Failures during the process of patient management
 Includes illegible handwriting, incomplete prescribing
order, vague instructions, prescription not recognized
& unknown prescriber
 Common communication errors
 Common errors include ‘g’ mistaken for ‘mg’
 4 mistaken for ‘U’
 Decimal point (.1 read as 1)
14.Apothecary system
15. Administration errors
 Medication administration error (MAE) is defined as “any difference between what the
patient received or was supposed to receive and what the prescriber intended in the
original order”
 It is risk areas of nursing practice while administering drugs
 Majority of these errors involved either dose omissions (42%) or wrong time
administration (50 %)
 MAE has a significant impact on morbidity, mortality, adverse drug event, and increased
length of hospital stay.
Thus, it increases costs to clinicians and healthcare systems
Administration error
 Incorrect administration techniques
 SC administered too deep
 Instilling eye drops in wrong eye
 IM injection at wrong site
 It involves wrong patient, wrong route of adm.,
wrong drug, wrong dose, wrong method, wrong time.
Causes of administration errors
 Lack of knowledge on drug
preparation, administration
 Fail to check 5 R’s
 Poor lighting
 Wrong calculations to determine
correct dose
 Noise and interruptions
Example of administration error
17. Transcription error
 Transcription error is a process of making an identical copy of prescription in the
medical records. Error occurs during this process is known as transcription error.
 An error that occurs during transcription of physicians order to the medication
administrative record (MAR)
 E.g. orders transcribed to wrong patient, wrong drug, wrong dose, wrong schedule
 Contributing factors:
 Incomplete or illegible nurse handwriting
 Use of abbreviations
 Lack of familiarity with drug names
18. Wrong time error
 Wrong-time medication administration error (WTMAE) is a high risk to patient
safety.
 It can result in severe harm, death or fatal consequences
 Standardized administration time to be followed
 Acceptable interval surrounding scheduled timing
WT errors are “dose administered 60 minutes before
or after scheduled time”
Example for wrong time administration
 A 60-year-old man was admitted to the hospital for a total knee arthroplasty. During the
admission process in the early evening, the surgical resident restarted his maintenance
home medications, including oral dofetilide (an antiarrhythmic agent) taken every 12
hours. In the electronic health record, drugs ordered for "q12 hour" dosing are scheduled
for 6 AM and 6 PM by default. The overnight nurse saw that the morning dose was
scheduled to be given at 6 AM, but the patient was scheduled to leave for the operating
room before 6 AM, so she gave the dose early, at 4 AM. During his preoperative
assessment at around 6 AM, the patient was noted to have severe QTc prolongation on
his electrocardiogram, putting him at high risk for torsades de pointes, a sometimes fatal
arrhythmia. Considering the acute ECG changes (prior QTc intervals were normal), surgery
was canceled and the electrophysiology service was consulted.
19.Deteriorated drug error
 The drug to be given to patient has been unchecked or improperly
stored and deteriorated prematurely at appropriate place leading to
deteriorated drug error
 Monitoring of expiry dates become essential
 Refrigerated drugs being stored at room temperature or freezer
 For example, administering insulin that has been frozen.
20.Work environment
21. Monitoring error
 Failing to monitor the health status of the patient prior or post drug
administration
 Inadequate drug therapy review
 Ordering serum drug level tests and not reviewing test results
 Prescribing antihypertensive drugs and failing to monitor blood pressure
 Giving antipyretics and not assessing temperature
 Administering Digoxin and not monitoring pulse/ heart rate

    15. Administration errors Medication administration error (MAE) is defined as “any difference between what the patient received or was supposed to receive and what the prescriber intended in the original order”  It is risk areas of nursing practice while administering drugs  Majority of these errors involved either dose omissions (42%) or wrong time administration (50 %)  MAE has a significant impact on morbidity, mortality, adverse drug event, and increased length of hospital stay. Thus, it increases costs to clinicians and healthcare systems
  • 66.
    Administration error  Incorrectadministration techniques  SC administered too deep  Instilling eye drops in wrong eye  IM injection at wrong site  It involves wrong patient, wrong route of adm., wrong drug, wrong dose, wrong method, wrong time.
  • 67.
    Causes of administrationerrors  Lack of knowledge on drug preparation, administration  Fail to check 5 R’s  Poor lighting  Wrong calculations to determine correct dose  Noise and interruptions

    17. Transcription error Transcription error is a process of making an identical copy of prescription in the medical records. Error occurs during this process is known as transcription error.  An error that occurs during transcription of physicians order to the medication administrative record (MAR)  E.g. orders transcribed to wrong patient, wrong drug, wrong dose, wrong schedule  Contributing factors:  Incomplete or illegible nurse handwriting  Use of abbreviations  Lack of familiarity with drug names

    18. Wrong timeerror  Wrong-time medication administration error (WTMAE) is a high risk to patient safety.  It can result in severe harm, death or fatal consequences  Standardized administration time to be followed  Acceptable interval surrounding scheduled timing WT errors are “dose administered 60 minutes before or after scheduled time”
  • 71.
    Example for wrongtime administration  A 60-year-old man was admitted to the hospital for a total knee arthroplasty. During the admission process in the early evening, the surgical resident restarted his maintenance home medications, including oral dofetilide (an antiarrhythmic agent) taken every 12 hours. In the electronic health record, drugs ordered for "q12 hour" dosing are scheduled for 6 AM and 6 PM by default. The overnight nurse saw that the morning dose was scheduled to be given at 6 AM, but the patient was scheduled to leave for the operating room before 6 AM, so she gave the dose early, at 4 AM. During his preoperative assessment at around 6 AM, the patient was noted to have severe QTc prolongation on his electrocardiogram, putting him at high risk for torsades de pointes, a sometimes fatal arrhythmia. Considering the acute ECG changes (prior QTc intervals were normal), surgery was canceled and the electrophysiology service was consulted.

    19.Deteriorated drug error The drug to be given to patient has been unchecked or improperly stored and deteriorated prematurely at appropriate place leading to deteriorated drug error  Monitoring of expiry dates become essential  Refrigerated drugs being stored at room temperature or freezer  For example, administering insulin that has been frozen.

    21. Monitoring error Failing to monitor the health status of the patient prior or post drug administration  Inadequate drug therapy review  Ordering serum drug level tests and not reviewing test results  Prescribing antihypertensive drugs and failing to monitor blood pressure  Giving antipyretics and not assessing temperature  Administering Digoxin and not monitoring pulse/ heart rate

    Summary  More peopledie annually from medication errors than from workplace injuries.  An error in the prescribing, dispensing, administration of a drug irrespective of whether such errors lead to adverse consequences or not.  In India, Medication Error is just a TERM and its significance is undervalued and remains unreported  Reported incidence of this iatrogenic disease related to medication error- tip of the iceberg  medication error can be visualized with the SWISS CHEESE MODEL OF SYSTEM accidents  Medication errors are descibed under prescription errors, transcription errors, administration errors  Based on the causes of errors the NCC MERP Index is formulated to categorize medication errors from Category A- I  Appropriate monitoring, good team communication, knowledgeable staff, RCA and policy on check of medication errors can reduce its incidence and make patient more safe
