Description
Delivering safe care involves understanding the root of the
defects that impact safe. In order for us to understand our
systems of care, we need a diagnostic journey that moves out of
a model for judgment and into a model for learning. A number of
data sources are available for organizations to identify the rate
and type of harm that patients may be experiencing, Using the
data from diagnostics can be helpful to draw conclusions to help
focus improvement efforts. During this session, participants will
learn and share their experiences with using diagnostics to
improving safety.
Objectives
Describe the diagnostic journey that organizations must take in
order to improve patient safety
List the diagnostic tools available to identify defects
Develop a plan to use diagnostics in your organization

Diagnostic Journey
Do people die unnecessarily every day in our
hospitals?
In order for us to understand this, we need a
diagnostic journey that moves out of a model for
judgment and into a model for learning.
The Mortality Diagnostic – 2x2 Matrix
Review most recent 50 consecutive deaths.
Place them into a two by two matrix based on:
- Was the patient admitted for palliative care?
- Was the patient admitted to the ICU?
Focus your work initially on boxes that have at least 20% of
your mortality.
Diagnostic – The 2 x 2 Matrix
Admitted to the ICU?
Yes
Admitted
for
Palliative
Care
Only?
No
Yes
Box #1
Box #2
No
Box #3
Box #4
The Mortality Diagnostic
- Failure to Recognize, Plan, Communicate
Analyze deaths in box 3 and 4 for evidence of failure to:
recognize, communicate, plan.
This will help you understand the local environment.
Recognize, Communicate, Plan
- Failure
to Recognize: Any situation in which a patient has
died and there was evidence that an intervention could have
been made anytime prior to the patient’s death Example: the
staff was worried, change in heart rate, change in respiratory
rate, change in blood pressure, change in O2 saturation or
change in consciousness or neurological status that was not
responded to.
- Failure to Plan, such as: diagnosis, treatment, or calling a
rescue team.
- Failure to Communicate: Patient to staff, clinician to
clinician, inadequate documentation, inadequate supervisor,
leadership (no quarterback for the team), etc.
The Mortality Diagnostic
- The Impact of Care
Evaluate ALL deaths in box 3 and box 4 to
assess the estimated impact of our care on
mortality:
*As you review the deaths in box 3 & 4, ask
yourself the questions honestly (focusing on
learning, not judgment):
–
–
Was perfect care rendered?
If perfect care wasn’t rendered, could the outcome
of death have been prevented if the care had been
better?
–
What number of deaths could have been prevented?
The Mortality Diagnostic
- Evidence of Adverse Events
Analyze deaths in box 3 and 4 for evidence of adverse events
using the Global Trigger Tool.
This will give some further direction to local problems.

Accepting the Harm Burden
Concept of moving from a focus on error
and the preventable to the measurement
of global institutional harm whether
preventable or not
Definition of Harm
In the IHI Global Trigger Tool, the definition used
for harm is as follows:
Unintended physical injury resulting from or
contributed to by medical care that requires
additional monitoring, treatment or hospitalization,
or that results in death.
New (Harm)
vs. Old (Errors)
Concentrates less on
people more on
systems
Looks at all unintended
results
Makes measurement
easier
Concentrates on harm
and those errors that
cause harm
Errors are the focus of
discussion and solutions
Tends to focus only on
those results felt to be
related to error, ignores
other events
Requires judgment
Human found
responsible for most of
the errors
Why Use Trigger Tools?
Traditional reporting of errors, incidents, or
events does not reliably occur in the best of
health care cultures
Voluntary methods markedly underestimate
adverse events
Events can be reliably detected without resorting
to as yet unproven electronic surveillance
methods
Can be integrated into a good sampling
methodology to follow event rates over time

Not all triggers mean there was harm!

How it is Actually Done
1 - Set your timer for 20 minutes
2 - Review the coding summary (look for ecodes and obvious events)
3 - Review the discharge summary
4 - Review the lab
5 - Review the x-ray reports
6 - Review the procedure notes
7 - Any time left over, review nurse notes
Example of a Trigger:
Transfer to higher level of care
Endoscopy
Post procedure somnolent and hypotensive (BP 80) transferred to
ICU
Placed on Bi-Pap
Received standard meperidine and midazolam for procedure
Given flumazenil; stayed in unit 12 hours.
Concurrent Review
• Definition of Concurrent Review:
- Real-time view of patient care related to the specific
quality indicator being measured.
• Goal:
- Improve quality of care during present patient
admission.
• Reviewer Qualifications:
- Adequate (clinical) knowledge/experience of subject
matter and ability to synthesize and provide
feedback.
Concurrent Review Process
Identify patients with a need for daily review
– This can be the most challenging piece
– Use IT/administrative systems when possible
Review specifics of chart
Analyze and synthesize information
Provide feedback
(with the potential for an intervention …)
– One-on-one dialogue
– Weekly Reports/feedback from leadership
– Stats
– Outliers
– Review of guideline in question
– Documentation issues
– Staff Kudos!

Patient Module
The Patient Module is meant to function as a reality check
regarding what patient perceive as helpful and valuable in their
inpatient care.
Qualitative Measure
Patient Module
Identify five adult patients scheduled for discharge to
the home setting and who are capable of
participating in a brief interview.
First explain the purpose of the interview and obtain
permission.
Be sure to inform patients as to what information will
be noted and how it will be used.
Patient Module
Only interview patients who are willing to participate.
Record some brief notes with the patient’s comments and
perspectives in the worksheet.
Analysis
The modules and various waste streams described in this Tool
represent the starting point in a journey to reduce significant
waste in an acute care hospital.
Observation Method
Direct observation of a process in the natural setting
Developed by Ken Barker at Auburn University
Observation Method
The method is easily understood,
Data are easy to use for identifying trends and benchmarking,
Data are available within hours
The method is systems oriented and views errors in doses as
defects in a system,
The method is objective and does not assign blame
Observation Method
The method is defensible, with all doses being examined and
errors witnessed
The method enables problem-based continuing education that
focuses on “our” errors
The method facilitates evidence-based testing that can evaluate
proposed system changes
Quality can be measured quantitatively by third parties
Pharmacy Interventions

Types of Measures
Process
– Measure the effectiveness of a process, which if done well should deliver
a good outcome
Outcome
– Measure the effectiveness of a change or intervention in delivering the
desired outcome
Balancing Measure
Why is it important to link multiple measures?
No one measure provides the complete picture
Activities in one area impact results in an other
Process measures should be linked through evidence to
outcomes
Balancing measures help understand unintended consequences
Focus on the Vital Few!
There are many things in life that are interesting
to know.
It important to work on those things that are
essential to quality and safety.
The challenge, therefore, is to be disciplined
enough to focus on the essential, vital few.
