Слайд 2Objectives
Outline major principles for systems thinking and reliable design
Describe human
error categories and explain ways in which human factors engineering impacts safe process design
Differentiate improvement models that have been utilized outside and inside of the healthcare industry
Слайд 3CASE #1
35 year old male
Seeking opthamology referral
Lab results for a different
patient were reviewed
Слайд 4CASE #2
• 52 year old patient
• History of GI bleeds and
ulcers
• Prescribed an NSAID
Слайд 6Hazards
• Hazard activities (i.e., behaviors) or conditions that pose threat of
harm
• Sometimes hazards lie hidden in the system, and sometimes they are quite obvious
Слайд 8Healthcare World before 1999-2000
• Quality/safety assumed to be excellent.
• No business
case to improve safety/quality.
• No local expertise, research or best practices.
• Little concerted effort by board, C-suite or physicians to improve quality/safety
• Combination of wrong mental model and no incentive leads to predictable results
Слайд 9Healthcare World Now
• Growing business case for safety/quality
• Steady progression from
relatively weak pressures (social pressure, accreditation w/ low chance to fail,
transparency), eventually settling on “all of the above”
plus payment changes
• Capacity building: people, tools, measures and IT
• Transition from quality/safety to value
• Recognition of need to remake delivery system to
survive/succeed in new healthcare world
Слайд 10Why Is This So Hard?
• Medicine is complex
• High degree of
uncertainty
• Care across the continuum is challenging
• Diversity of workforce and
complexity of patients
Слайд 11Definition of Insanity
Insanity: doing the same thing over and over
again and expecting different results.
Albert Einstein
Слайд 12Error Causation and Prevention
Most preventable harm to patients receiving healthcare today
is caused by the unsafe acts of the various Practitioners who are trying to help them.
Слайд 15Systems Thinking
Refers to thinking in terms of:
Interdependencies
Interactions
Sequences
Слайд 16Systems Thinking
Provides a conceptual framework to help see and understand relationships
Helps
to avoid simplistic solutions to complex problems
Focus on interdependencies
Слайд 17Reliability Science
Definition of Reliability:
“the extent to which an experiment, test,
or measuring procedure yields the same results on repeated trials”
By Institute for Healthcare Improvement
“Failure free operation over time”
Relation to IOM’s aims: effectiveness, timeliness, and patient-centeredness.
Слайд 18High Reliability Organization (HRO)
Organizations despite functioning in complex, hazardous environments, have
very low error rates
Examples: airline industry, nuclear power, chemical plants, aircraft carriers.
One small error can lead to catastrophic consequences for not only the employees but also for the general public.
Слайд 19PRINCIPLES OF RELIABILITY SCIENCE
Anticipation: used to detect an error before it
occur.
Containment: control the consequences of errors
Слайд 20Checklists and other Systems

you.
Слайд 21The Culture of Low Expectations
“We suspect that these physicians and nurses
had become accustomed to poor communication and teamwork. A ‘culture of low expectations’ developed in which participants came to expect a norm of faulty and incomplete exchange of information [which led them to conclude] that these red flags signified not unusual, worrisome harbingers but rather mundane repetitions of the poor communication to which they had become inured.”
Drs. Mark Chassin and Elise Becher
Annals of Internal Medicine, 2002
Слайд 22Human Factors
• Human factors engineering focuses on human beings and
their interaction with each other, products, equipment, procedures, and the environment.
• Human factors leverages what we know about human behavior, abilities, limitations, and other characteristics to ensure safer, more reliable outcomes.
Слайд 26Forcing Functions
Be more careful, or….
Redesign the breaks
Слайд 27Error Proofing
1. Simplification
2. Standardization
3. Reduce reliance on memory
4. Improve access to
information
5. Use forcing functions and constraints
Слайд 28Error Proofing
6. Use visual controls
7. Leverage high-performance teams
8. Deploy redundancies
9.
Eliminate environmental factors
10. Make errors more visible

Слайд 34Model for Improvement
Three Questions
1) What is the aim?
2) How will
we know a change is an
improvement?
3) What changes can we make that will result in
an improvement?

F = FIND A PROBLEM
O = ORGANIZE TEAM

= CLARIFY YOUR KNOWLEDGE ABOUT THE PROCESS
U = UNDERSTAND SOURCES OF VARIATION
S = SELECT THE PROCESS IMPROVEMENT

Слайд 39F.O.C.U.S.
Find an improvement project (initiative):
Review related standards & documents
Analysis
of collected data
Identify problems & desired outcomes
Слайд 40F. O .C.U.S.
Organize ad hoc (task force) team:
Identify & involve stakeholders
(e.g. physicians, nurses, administrative …etc)
Cover all related departments to the improvement initiative
Select team members who best do or know the process to be improved
O
Слайд 41F.O.C.U.S.

all team member
Draw flow chart to clarify the process variation/problem
Collect data from all affected areas relevant to process & desired outcomes

LEAN: An effective approach for improving patient safety by process
design that improves reliability through standard work, mitigation, and continuous improvement
Слайд 49Focus Area of Lean
Lean:
Lean pioneered by Toyota, focuses on the efficient
operation of the entire value chain.
Focus areas:
Remove non-value added steps to:
Reduce cycle time
Improve quality
Align production with demand
Reduce inventory
Improve process safety and efficiency
Слайд 51Core Attributes for Safe, Reliable Systems
• Well-defined workflows
• Mistake-proofing principles
• Measurement
strategy
• Team members who share responsibility to provide safe, reliable care
Слайд 52The Science of Patient Safety
• New concepts: science of error causation
(“systems thinking”), complex systems, human factors, cognitive psychology, applied informatics…
• New attitudes: teamwork, discipline, professionalism, balancing “no blame” with accountability, disclosure…
• New skills: error analysis, leadership, change management...
Слайд 53
“We think that the anxiety, demoralization, and sense of loss of
control that afflict too many healthcare professionals today directly come not from finding themselves to be participants in systems of care, but rather from finding themselves lacking the skills and knowledge to thrive as effective, proud, and well-oriented agents of change in those systems…. A physician equipped to help improve healthcare will be not demoralized, but optimistic; not helpless in the face of complexity, but empowered; not frightened by measurement, but made curious and more interested; not forced by culture to wear the mask of the lonely hero, but armed with confidence to make a better contribution to the whole.”
