2ISMP Canada
- ISMP Canada is an independent not-for-profit
organization dedicated to reducing preventable
harm from medications. - Our goal is the creation of safe and reliable
systems for managing medications in all
healthcare environments. - www.ismp-canada.org
3ISMP Canada Services
- Voluntary Error Reporting Program report via
website - Error Reporting Software (Analyze-ERR)
provides electronic database of medication events
for storage, retrieval, follow up and analysis - Medication Safety Self Assessment (MSSA)
Hospital, Community Pharmacy, Complex Continuing
Care, LTC, Operating Room - Projects/ Service Contracts - e.g, Ontario
Medication Safety Support Service - Consulting Root Cause Analysis, Failure Mode
and Effects Analysis, Medication System Safety
Reviews - Education bulletins, presentations, interactive
workshops, student lectures
4Where are you from?
- Eastern provinces (NS, NF, NB, PE)
- Central (ON,QC)
- Western provinces (MB, SK, AB, BC)
- Territories (YK, NT, NU)
5Educational Objectives
- At the end of this workshop, participants will
have gained knowledge and understanding of - the importance of incident reporting
- the value of individual and aggregate incident
reviews - how system factors and human factors engineering
principles contribute to error potential and
system improvement in healthcare environments - system safeguards to reduce the risk of
preventable harm from medications.
6- Reporting incidents is important
7Ignorance is not bliss!
Reported errors (3-6)
8British Airways Incident Reports
9Goal is harm reduction
- High alert medications
- Vulnerable populations
- Gaps in medication use processes
10High Alert Medications
- High-alert medications are drugs that bear a
heightened risk of causing significant patient
harm when they are used in error. - ISMPs List of High-Alert Medications. Available
at www.ismp.org/Tools/highalertmedications.pdf.
11High-Alert Medications
- For example
- Opioids
- Insulin
- Anticoagulants
- Chemotherapy agents
12Incident Analysis (Root Cause Analysis)
- Three questions
- What happened?
- Why did it happen?
- What can be done to reduce the likelihood of a
recurrence?
13Why is there a need for RCA?
- Accidents result from a sequence of events and
tend to fall in recurrent patterns regardless of
the personnel involved. - All staff, even the most experienced and
dedicated professionals can be involved in
preventable adverse events.

- Structured individual incident analysis offers
more information to generate better solutions
16Case 1 - Morphine
- An elderly resident living in a LTC home was
receiving - palliative care, which included morphine 1 to 2
mg - subcutaneously q3-4h prn for analgesia.
- 10 mg morphine was administered instead of 1
mg by a nurse at the LTC home. - The attending physician and the residents
family were notified of the incident. The
resident subsequently died.
17Accountability???
- Nurse
- LTC Home
- Provincial Government
- 1, 2, 3
- 2 and 3
- None of the above
18Morphine CalculationAvailable concentration 15
mg/mL
- 1 mg 0.15 mL
- 1 mg 0.1 mL
- 1 mg 0.07 mL
- 1 mg 0.7 mL
19Morphine 15 mg/mL
- Correct calculation
- 1 mg 0.07 mL
- 2 mg 0.13 mL
- Incorrect calculation
- 10 mg 0.7 mL
20Which syringe was used?
0.07 mL (1 mg) or 0.13 mL (2 mg)
21- Have you changed your mind about accountability?
22Case 2 Warfarin
- 78-year old with bilateral leg ischemia, severe
CHF, dementia and a left lung mass - 2 week hospitalization - unsuccessful right
bifemoral artery bypass followed by above-knee
amputation of right leg - Discharged Aug 19 Rx warfarin 3 mg daily
- Sept 25 - RN discovered INR results not
available because not ordered on readmission to
Home - Stat INR ordered results so high they were
unreadable - Resident transferred to hospital by ambulance.
- Resident died later that evening due to internal
bleeding
23(No Transcript)
24Case 2 - Warfarin - Timeline
25Incident Analysis (RCA)
- What happened (went wrong)?
- Described in incident report and investigation
results reflected in timeline documentation - Why did it happen?
- Root cause analysis examines what led to or
contributed to the incident occurring
26Contributing Factors Root Causes
- Cause refers to a relationship or potential
relationship between certain factors that enabled
an event to occur - Cause does not imply blame
- True root causes are the earliest points where
action could have been taken to enhance the
support system to prevent the event or mitigate
the harm from the event
27Task Select Causes / Contributory Factors
- Discuss in pairs
- (2 minutes)
28Case 1 Warfarin
- 78-year old with bilateral leg ischemia, severe
CHF, dementia and a left lung mass - 2 week hospitalization - unsuccessful right
bifemoral artery bypass followed by above-knee
amputation of right leg - Discharged Aug 19 Rx warfarin 3 mg daily
- Sept 25 - RN discovered INR results not
available because not ordered on readmission to
Home - Stat INR ordered results so high they were
unreadable - Resident transferred to hospital by ambulance.
- Resident died later that evening due to internal
bleeding
29Causal or Contributory FactorsSelect your choice
- Prescriber forgetfulness
- General lack of monitoring effects of drugs
- Lack of knowledge of nurses
- Expectation that resident would deteriorate
rapidly based on medical condition - No clinical assessment during month
- All of the above
- None of the above
30What underlying causes exist?
- Ask a series of why questions until you have
worked well away from the sharp end (the
outcome of the incident) of the event to the
blunt end - Usually not just one cause many factors
- Sometimes called the five levels of why
-
31Sharp End vs. Blunt End
Adapted from the NHS Report Doing Less Harm,
2001
32Types of Cause and Effect Diagrams Tree Diagram
33Use of Diagrams
- Avoids hindsight bias
- things that were not seen or understood at the
time of the accident seem obvious in retrospect. - Institute of Medicine. Linda T. Kohn.(2000).
To Err is Human. Washington, D.C. National
Academy Press. p. 53. - Assists in identifying what are the best leverage
points for action
34(No Transcript)
35Is this a root cause?
- Bottom line question
- If this factor were eliminated or corrected,
would it have prevented the outcome or mitigated
the harm? - ? Would there be a real chance to prevent a
similar event from happening?
36Causal Statements
- The lack of a standardized protocol for warfarin
management with an embedded cuing mechanism,
increased the likelihood that an order for INR
testing would be omitted, leading to continued
administration of warfarin without dose
adjustment, with resulting internal hemorrhage
and death. - The lack of an established standardized protocol
to complete a full assessment and update the
resident treatment plan post-hospitalization
decreased the likelihood that omission of an
order for INR monitoring would be detected,
leading to failure to adjust warfarin therapy,
resulting in internal hemorrhage and death.

49- Responding to individual incident reports
50Need to change the way we think about errors
51The Person Approach
- The person approach focuses on the errors of
individuals, blaming them for forgetfulness,
inattention, or moral weakness. - J. Reason, March 18, 2000, BMJ
- Historically focused on individual performance
and not system issues - Fear of reprisals drives important information
underground - ? Blame and Shame
52- As healthcare professionals we are taught to
maintain competence, practice due diligence and
take care to avoid mistakes. - Systems theory states that although this is
necessary, it is not enough. - ?The way to prevent mistakes or mitigate harm
from mistakes is to redesign systems with
integrated safeguards, in addition to practicing
due care.
53Systems Approach
- Focus is on improving the processes, systems, and
environment in which people work, rather than
attempting only to improve individual skills and
performance
54The Systems Approach
- Recognizes that
- Humans are incapable of perfect performance
- Accidents are caused by flaws in the working
environment (system) and human errors that are an
expected part of any working environment - Accidents can be prevented by building a system
that is resilient to expected human errors
55The Systems Approach
- though we cannot change the human condition, we
can change the conditions under which humans
work. - Reason J. (2000). Human error models and
management. - BMJ, 320(7237) 768-770. Retrieved from
http//www.bmj.com/cgi/content/full/320/7237/768
56What about professional accountability?
- Does non-punitive mean blame-free?
- Does a system approach mean that individual
practitioners are not accountable for their
actions?
57Shared AccountabilityJust Culture
- it is about creating a reporting environment
where staff can raise their hand when they have
seen a risk or made a mistake..where risks are
openly discussed between managers and staff. - while we as humans are fallible, we do
generally have control of our behavioural
choices. - good system design and good behavioural choices
of staff together produce good results. It has to
be both. - Marx D, Comden SC, Sexhus Z (2005). Our inaugural
issue In recognition of a growing community.
The Just Culture Community News and Views, 1(1).
58 59Reality of Health Care Environments
- Cognitive overload
- Workloads
- Multitasking
- Interruptions
- Difficult technology
- Look-alike packaging and labelling
- Sound-alike medication names
60Potter et al. 2004. Advances in Patient
Safety139-51.
61Workarounds At-Risk Behaviours
- Natural tendency to take shortcuts to make
completion of tasks easier or increase efficiency
- Workarounds occur when a procedure or action does
not fit with the workflow
62Examples of At-Risk Behavioursin the Medication
Use Process
- Not verifying patient allergies before
prescribing / dispensing / administering
medications - Writing incomplete orders or orders with
hazardous abbreviations - Not questioning unusual or incomplete orders
- Not welcoming/supporting clarification of unclear
orders - ISMP Medication Safety Alert! October 7, 2004
63Workaround Research
- 84 percent of physicians and 62 percent of
nurses/other clinical-care providers have seen
co-workers taking shortcuts that could be
dangerous to patients. - Fewer than 10 percent of physicians, nurses and
other clinical staff directly confront their
colleagues about their concerns, and 1 in 5
physicians said they have seen harm come to
patients as a result. - The 10 of healthcare workers who raise these
crucial concerns observe better patient outcomes,
are more satisfied and are more committed to
staying in their jobs. - American Association of Critical Care Nurses
- www.silencekills.com (2005)
64- Humans have limitations that impact on
performance
65What is Human Factors?
- A discipline concerned with design of systems,
tools, processes, machines that takes into
account human capabilities, limitations, and
characteristics - Human factors engineers work to make the
environment function in a way that seems natural
to people

68Why does design matter?
- Some designs cause problems that are inconvenient
- Some designs cause problems that are unsafe

71Confirmation Bias / Cognitive Tunnel Vision
- Leads one to see information that confirms our
expectations, rather than information that
contradicts our expectations.
72Look-alike Labelling Leads to Tragedy
- 80 year old nursing home resident received 7
doses (27 grams) of chloral hydrate instead of
potassium chloride liquid as intended - ISMP Canada Bulletin 2005
- Vol 5 Issue 7
73Key Findings
- Similar packaging and labelling
- No barcode verification at the vendor level
- Lack of systematic check of drug identification
number in the pharmacy - ? Fragmented medication review process
- Resident had received a very high dose of KCl
(200 mEq daily) to manage furosemide-induced
hypokalemia for more than one year - Alternative management strategies for CHF not
considered
74Recommendations
- Manufacturer
- Labelling and packaging changes
- Pharmacy
- Systematic process for checking DIN numbers
barcoding - Adequate space for filling and checking
- Wholesaler
- Barcode verification
- Special attention to high alert medications
(i.e., segregation, additional safeguards) - Home
- ? Interdisciplinary medication review at least
every 6 months - Staff education re pharmacology, signs of adverse
drug events, principles of medication system
safety
75- Healthcare system design relies heavily on memory
76(No Transcript)
77Memoryhas inherent human limitations (how long
and how much)
- Limited memory span 7 /- 2 pieces of
information can be held in short term memory
when attention is full - Factors affecting memory
- Stress
- Fatigue and other physiological factors
- Repetition of behaviour

79Actions to support memory
- Limit interruptions
- Minimize reliance on memory
- Minimize travel
80Attention hasinherent human limitations
81How many passes?
82Anything else?
83Inattentional Blindness
- Failing to see what should have been plainly
visible - Because attention is not focused on it
- Most of our perceptual processing occurs outside
of conscious awareness - Attentional resources are finite
- Amount of attention required is affected by
practice and task difficulty
84Aids to Maintaining Attention
- Be conscious of how many tasks you are trying to
accomplish at once - Work to avoid interruptions
85- Given that there are problems in our systems
leading to increased risk of errors, how can
understanding human factors help us to make
changes?
86Safety Strategies
- Eliminate
- Remove the hazard
- Control
- Provide safeguards
- Accept
- Not an option if a serious hazard is
identified, the minimum safety strategy is a
control measure
87Hierarchy of Effectiveness(Summary)
- Forcing functions and constraints
- Automation / computerization
- Simplification / standardization
- Reminders, checklists, double checks
- Rules and policies
- Education and information
88Forcing Function
- Cohen defines a forcing function as a design
- feature that makes it impossible to perform a
- specific erroneous act.
- Cohen, M.R. (1999). Medication Errors.
Washington, D.C. American Pharmaceutical
Association. - Examples
- Gas line fittings in operating rooms
- Automobile design reverse gear
- On-line forms
89Insulin Safety Needle
- Forcing function
- needle automatically covered by sleeve after
injection - Needle can only be used once
- Visible reminder red indicator when used
- NovoFine Autocover

91Simplification / Standardization
- For example, standardized protocols for high
alert drugs that are integrated into work flow
via pre-printed order forms or electronic CPOE) - e.g., for anticoagulants
- Define the roles of each team member, scope of
INRs results requiring MD attention, required
monitoring, etc.
92Human Factors Guiding Principle
- Fit the task or tool to the human, not the other
way around
- Vicente, Kim. (2004). The Human Factor
Revolutionizing the way people live with
technology. Vintage Canada
93- Earlier case examples were used to illustrate
individual incident analysis. - Aggregate analysis allows for analysis of
multiple reports
94Aggregate Analysis
- A process by which analysis is conducted on a
cluster of reports involving common factors that
are pre-defined for achieving a specific
objective - e.g. drug or drug class, age category, care
setting
95ISMP Canada LTC Incident Review
- 1066 incidents reviewed
- 25 caused harm
- Warfarin, fentanyl patch and hypoglycemics most
commonly associated with errors resulting in harm
96ISMP Canada Analysis of LTC Incident Reports
- Opioids
- 1. Order misinterpretation
- Contributing factors Dosing unit mix-ups
dangerous abbreviations - 2. Dose omissions
- Contributing factors Interruptions order not
transcribed to MAR medications not available
from pharmacy - Fentanyl patch errors
- Contributing factors resident ordered fentanyl
patches possibly not a suitable candidate old
patch not removed every 72 hour schedule leading
to dose omissions
97LTC Incident Analysis (Contd)
- Insulins
- 1. Mix-ups between different types of insulin
- Contributing factors Look-alike / sound-alike
close proximity in storage - 2. Incorrect dose
- Contributing factor Dose requirement changes
depending on various resident factors (e.g. blood
glucose level, dietary intake...etc.) - 3. Incorrect time of administration
- Contributing factors Time dependent nature of
insulin administration resident not available at
time of administration order entry /
transcription error
98LTC Incident Analysis (Contd)
- Anticoagulants
- 1. Drug monitoring errors related to warfarin
- Contributing factor The linkage of the various
steps of the warfarin administration and
monitoring process
99Conclusion
- Reports ? Analysis ? Solutions development ?
Dissemination - Quality of analysis greatly depends on the
quantity / quality of incidents received - Reports rich in detail ? High quality solutions

109- Role of the Medical Director and the Professional
Advisory Committee
110Role of Medical Director and Professional
Advisory Committee (PAC)
- Set the tone for the Home
- Help sell the culture
- Communicate expectations e.g.,
- Incident management
- Improvement approach
- Clinical and organizational best practices
111Role of Medical Director and PAC
- Participate in ensuring that a formal incident
response framework is established and understood
by all staff - Immediate action to be taken by staff re care of
resident and prevention of imminent recurrence,
quarantine of articles/securing health record,
notifications - Support for staff
- Disclosure to resident/family who is the key
organizational contact for family follow up - Reporting form readily available
112Role of Medical Director and PAC
- Review internal and external reports of
medication incidents - Review drug utilization reports
- Participate in MSSA, review results, and guide
improvement action - Work to develop standardized protocols, e.g.,
pre-printed orders - Develop expectations for medication reconciliation
113Medication Reconciliation
- Essence is making sense of patients medications
and resolving conflicts between different sources
of information to minimize harm and maximize
therapeutic effects
114Medication Incident Management
- How to use incident reports
- As part of notification process for incidents
that have occurred - Trend analysis within a home or organization
- Monitoring tool for effectiveness of
interventions - Educational tool widely share de-identified
details for learning purposes
115How is the PAC involved in in your own settings?
- Review of incident reports by PAC (not just
summaries) - Participation in MSSA
- Development of standardized protocols
- All of the above
- None of the above
116Medication Incident Management
- How not to use incident reports
- As an indicator of individual employee competence
or for disciplinary purposes - As part of statistical calculation of incident
rates
117Communication of Results
- Consider communicating the information learned
from incident analysis in a generic way to those
who could also benefit from the information - Within the home
- Within the corporation, if applicable
- Outside the organization
118ISMP Canada Safety Bulletins
119Goal a culture of safety
