Patient Safety and Quality
Improvement
What, Why and How Can We Teach It?
ACGME Requirements…
Practice-based Learning and Improvement: Residents must demonstrate the ability to
investigate and evaluate their care of patients, to appraise and assimilate scientific
evidence, and to continuously improve patient care based on constant self-evaluation
and life-long learning.
identify strengths, deficiencies, and limits in one’s knowledge and expertise;
set learning and improvement goals;
identify and perform appropriate learning activities;
systematically analyze practice using quality improvement methods, and implement changes with
the goal of practice improvement;
incorporate formative evaluation feedback into daily practice;
locate, appraise, and assimilate evidence from scientific studies related to their patients’ health problems;
use information technology to optimize learning;
participate in the education of patients, families, students, residents and other health professionals.
Systems-based Practice: Residents must demonstrate an awareness of and
responsiveness to the larger context and system of health care, as well as the ability
to call effectively on other resources in the system to provide optimal health care.
work effectively in various health care delivery settings and systems relevant to their clinical specialty;
coordinate patient care within the health care system relevant to their clinical specialty;
incorporate considerations of cost awareness and risk-benefit analysis in patient and/or populationbased care as appropriate;
advocate for quality patient care and optimal patient care systems;
work in interprofessional teams to enhance patient safety and improve patient care quality; ‘
participate in identifying system errors and implementing potential systems solutions.

Patient Safety
1991- Harvard Medical Practice Study, NEJM
Reviewed >30,000 medical charts
Adverse event was defined as: “injury that was caused by medical
management (rather than the underlying disease) and that prolonged
the hospitalization, produced a disability at the time of discharge or
both.”
4% of admissions were injured
13.6% of these adverse events led to death
>50% were preventable (although lots of disagreement on this)
Brennan, T. A., L. L. Leape, et al. (1991). "Incidence of adverse events and negligence in hospitalized
patients. Results of the Harvard Medical Practice Study I." N Engl J Med 324(6): 370-376.
1999/2000- Institute of Medicine report: “To Err is Human: Building a Safer
Health System”
Estimated 44,000-98,000 Americans die each year from medical
mistakes
50% of these deaths were counted as “not preventable”
Deaths due to preventable adverse events were greater than MVA,
breast cancer or AIDS
Equal to a jumbo jet crashing every day

D.C., National Academy Press.

impact on patient safety
and quality of care,
identify vulnerabilities and
safeguards
MRI Tracer
Pharmacy Tracer
Thoracentesis Tracer
GI consult Tracer

2.
Identify “layers of
cheese”
Identify “holes in the
cheese”
How do we analyze these
adverse events?
Root
Cause Analyses
What happened, why did it happen, what can
be done?
Triggered from actual events and close calls
with “severe” potential
Activity: Mock RCA
4 Basic Steps in an RCA
1) Identify the Problem
2) Event Flow Chart
3) Cause and Effect Diagram
4) Develop Solutions or “Actions”
Strong- architectural/physical plant changes, new devise,
engineering control or interlock, remove unnecessary steps
Intermediate- increase staffing/decrease in workload, software
enhancement modifications, checklists
Weak- double checks, warning and labels, new procedure
memorandum, training
What is Human Factors Engineering?
Designing systems devices, software and tools to fit
human capabilities and limitations
Minimize error and optimize safety
Using established methods to gather unique information
about
Hidden needs of the end-user
Unexpected interactions between the system and the
user
Taking advantage of knowledge bases about human
system interaction

“ At one point, the pulmonologist tried to put a mask over [Steve Jobs] face when he
was deeply sedated. Jobs ripped it off and mumbled that he hated the design and
refused to wear it. Though barely able to speak, he ordered them to bring five
different options for the mask and he would pick a design he liked…He also hated the
oxygen monitor they put on his fingers. He told them it was ugly and too complex.”
- New Yorker, Nov 14th
Activity: HFE Workshop
Identify and understand how
human strengths and
weaknesses affect system
design, interact with the
environment and contribute
to errors

Epidemiology of Quality Problems
1987: Wennberg et al compared New Haven and
Boston university hospitals
In 1982 expenditures per head for inpatient care were
$451 in New haven and $889 in Boston
Found widespread deviations from best practices
Wennberg, J. E., J. L. Freeman, et al. (1987). "Are hospital services rationed in New Haven or over-utilised in
Boston?" Lancet 1(8543): 1185-1189.
Many studies since have demonstrated large
variations in quality of care based on race, income and
gender (“ healthcare disparities”)
2003: McGlynn et al evaluated 12 metropolitan areas
in the US, looked at performance on 439 indicators of
quality of care for 30 acute and chronic conditions as
well as preventative care
54.9% of patients received recommended care
McGlynn et al. “The Quality of Health Care Delivered to Adults in the United States.” NEJM 2003; 348: 2635-45
Question: “how can doctors and hospitals be practicing high quality,
evidence-based medicine yet have such stunningly different approaches
to the same problem?”
What is Quality?
In 2001, IOM report: Crossing the Quality
Chasm defined 6 aims for a quality healthcare
system
Patient safety
Patient-centeredness
Effectiveness
Efficiency
Timeliness
Equity
• Quality is not just delivery of EBM, its much broader
Lean: Maximizing value-added processes, eliminating waste,
from the perspective of the end user (the PATIENT)
Six Sigma: Remove defects, reduce variability
QI Tools: Process Flow Diagrams
Graphic representation of the sequence of
steps in a process
Often, one member of the process is not
aware of what the other members are doing
Stay as high as possible, for as long as
possible (the Woodstock rule)

What is an Ishikawa Diagram
Developed by Ishikawa in Kawasaki Shipyards
Made famous when used in the development of the Mazda Miata
AKA Fishbone diagram
Brainstorming Tool
Tool for uncovering and describing factors that influence an
outcome
3 steps:
1.
Identify the problem
- A concise problem statement
- i.e. Long Wait times in Clinic
2. Create headers for the fish skeleton
- Need to be mutually exclusive and comprehensive
- i.e. People, Policy, Methods, Materials, Other
3. Investigate each of the headers for more concrete examples
- i.e. understaffing at the pharmacy would fall under Man Power
Fishbone Example: Long Wait
Times in Primary Care Clinic
People
Policy
HIPAA limits abilities
of front desk personel
Nursing understaffed
Each physician likes things
done differently
Allscripts communication rather
than verbal
Redundancy- pts filling out same forms
and questions multiple times
Not enough exam rooms
Too many steps in the
process- precheckin,
Outdated new patient questionnaires
checkin, nursing intake etc..
Methods
Materials
Long wait times

Another Example of a PDSA:
Inpatient Medicine
PLAN:
Thoracentesis samples sent in wrong tube
- Trace process from inpatient medicine floors, Interventional
Radiology
- Fishbone diagram- pH and CBC were primary problems
(consistent with pareto’s law)
DO:
Modify the Medicine Order Set
STUDY: Following the intervention review what % of thoracentesis tubes were
sent incorrectly
ACT:
Educate IR about our new order set
If intervention doesn’t work, how can we modify it
Another Example of a PDSA:
Outpatient Medicine
PLAN:
Identify a quality measure to target
i.e. documentation of goals of care, flu shots, colonoscopy
screening
Each resident reviews their current processes and
success rate with regard to the measure
What % of patients have appropriate documentation
What are some barriers to meeting this measure
• May need flow diagram, fishbone, FMEA
DO:
Develop an intervention (or action) Resident or staff education
Make forms more available
EMR modifications
STUDY: Following the intervention review what % of patients have
appropriate documentation
ACT:
If intervention works, spread the word!
If intervention doesn’t work, how can we modify it
Logistics
Initiative needs to come from the TOP
Need to appoint a “QI/PS” team leader
Allocate time- should start with “protected time” for both
the attendings and the residents
Suggestions:
•
•
•
•
•
Noon-conference
Morning report
Rounds
Outpatient block
Orientation
Part didactics but mostly active learning
Evaluation and feedback are important so that it seems
like a “real” part of the curriculum
Goals for the Future
Other specialties and disciplines: surgery, OB/GYN,
psychiatry, dermatology, nursing etc..
Teach the teacher- dry run of our SGIM workshop “A
Toolbox for Teaching Patient Safety”
Integration into orientation for both MS III and PGY1s
Integration into basic clinical months (rather than isolated
electives)
Collaboration with other departments here at USF:
psychology, engineering, public health
