Chapter 15: Risk Management in Ambulatory Care Settings
Ambulatory Settings
There has been a steady flow of clinical services out of hospital settings into more cost-effective outpatient settings
Risk management is as important in the outpatient setting as it is in the inpatient, especially as outpatient settings are not subject to accreditation
Of all paid malpractice claims, a greater number are coming from the ambulatory setting than from inpatient alone
Why the increased risk?
Ambulatory settings differ from inpatient in that they do not have the same mix of specially trained professionals managing patient care 24 hours a day including detailed documentation, observation, decision support teams
Ambulatory setting provides infrequent care spread over time and patients are generally seen by personnel with a lower level of training performing tasks in multiple areas
Assessment of the Practice Setting
Risk Managers need to assess the risks inherent to the specific site
Management of risk in the ambulatory setting sites on 3 core principles:
A culture of safety
Good employment practices
Ethical business practices
Culture of Safety
It is important to recognize that human errors are inevitable and leads to ways to strengthen the system of care rather than punishment
4 Key Features
Psychological safety
Active leadership
Transparency
Fairness
Good Employment Practices
Under the principle of vicarious liability, the facility owner is legally responsible for the actions of their employees
Potential risks:
Non-physician employee exceeding their legally authorized duties
Inappropriate actions of employees
Fair employment practice issues
Ethical Business Practices
The risk manager must guard the practice against fraud and abuse by ensuring
Appropriate billing practices
Compliance with Stark Law
No inappropriate upcoding of claims
High Risk Areas
Missed diagnoses
Medication risks
Infectious risks
Communication
Documentation

Infectious agents
Toxic substances
Drugs
Carcinogenic agents
Health Effects Associated with Work Environment
Health risks for pregnant workers and the unborn fetus
Various lung diseases
Dermatologic problems
Bladder cancer among dye workers
Leukemia among workers exposed to benzene
2
Study Designs Used in Environmental Epidemiology
Descriptive studies provide information for setting priorities,
identifying hazards, and formulating hypotheses for new
occupational risks.
21. Etiologic studies can be used to show exposure-effect
relationships.
3
Retrospective Cohort Studies
Various end points are used to study the effects of occupational
exposures.
Morbidity: self-reports of symptoms and results of clinical
examinations
Mortality: comparison of mortality rates of exposed workers
with nonexposed workers in the same industry
4
Collection of Exposure Data
Employment records often are used and may include:
Personal identifiers to permit record linkage
Demographic characteristics
Work history
Information about potential confounding variables, e.g., medical
history, smoking habits
22. 5
The Healthy Worker Effect
Observation that employed populations tend to have a lower
mortality experience than the general population.
The healthy worker effect may reduce the measure of effect for
an exposure that increases morbidity or mortality.
6
Ecologic Study Designs
One use is the study of the health effects of air pollution.
Researchers measure the association between average exposure
to air pollution within census tracts and the average mortality in
those census tracts.
Unable to controI for individual factors, e.g., smoking habits
7
23. Case-Control Studies
Compared with cross-sectional study designs, case-control
studies can provide more complete exposure data.
However, precise quantitation of exposure and unobserved
confounding may be difficult to achieve.
8
Toxicologic Concepts Related to Environmental Epidemiology
Dose-response
Threshold
Latency
Synergism
9
Dose-Response Curve
24. Graph that is used to assess the effect of exposure to a chemical
or toxic substance upon an organism.
10
Threshold
The lowest dose at which a particular response may occur
11
Latency
The time period between initial exposure and a measurable
response
Latency can range from seconds (acute toxic agents) to years
(mesothelioma).
The long latency of health events in environmental research
makes the detection of hazards difficult.
25. 12
Synergism
A situation in which the combined effect of several exposures is
greater than the sum of the individual effects.
Example: Study conducted among asbestos insulation workers
demonstrated a synergistic relationship between asbestos and
smoking in causing lung cancer.

Between 1988 and 2002, percentage of children with elevated
blood lead levels declined steeply
18
Electric and Magnetic Fields
Sources include power lines, microwave ovens, stoves, clocks,
cellular phones.
Los Angeles and Swedish studies found an association between
residential proximity to power lines and childhood cancer risk.
U.S. and Norwegian studies found an increased risk for male
breast cancer among male electrical workers.
19
Ionizing Radiation
Consists of either particle energy (e.g., highly energetic
protons, neutrons, and α and β particles) or electromagnetic
energy (e.g., γ-rays and X-rays)
30. Sources of ionizing radiation can be natural or synthetic.
20
Ionizing Radiation (cont’d)
Natural sources--examples are radon and cosmic rays.
Radon is one of the largest sources of human exposure to
ionizing radiation and may be the cause of about 21,000 deaths
from lung cancers in the U.S.
Synthetic sources--examples are medical x-rays and nuclear
generators.
Allergens and Molds
Allergens--substances that provoke an allergic reaction in
susceptible individuals
Allergic reactions range from dermatitis, asthma, and itchy eyes
to anaphylactic shock.
21
Physical and Mechanical Energy
31. Include agents associated with unintentional injuries
Unintentional injuries are a leading cause of death within the
age group 1-44 years in the U.S.
Also include such factors as noise, vibration, and extremes of
temperature
22
Global Warming

unnecessary disability, or untimely death whose occurrence is a
warning signal that the quality of preventive or medical care
may need to be improved
23
32. Environmental Hazards Found in the Work Setting
Biologic hazards--Hospital employees, sewage workers, and
agricultural workers may be exposed to hazardous biologic
agents. For example, HIV may infect hospital workers through
accidental needle sticks.
Mineral and organic dusts--Examples include coal dust (mining
and black lung disease) and rubber dust (COPD).
24
Environmental Hazards Found in the Work Setting (cont’d)

Studies conducted in New York City, St. Louis, and Tennessee
have shown a correlation between increases in daily mortality
and increased air pollution.
29
35. Environmental Tobacco Smoke (ETS)
Nonsmokers who work in a smoking environment have reduced
pulmonary function compared to nonsmokers in a smoke-free
work environment.
ETS causes 3,000 lung cancer deaths annually among
nonsmokers.
ETS is associated with children’s bronchitis, pneumonia, and
asthma.
30
Nuclear Facilities

Chapter 14
Molecular and Genetic Epidemiology
Learning Objectives
Differentiate between molecular and genetic epidemiology
Describe principles of inheritance and sources of genetic
variation
Define epidemiologic approaches for the identification of
genetic components to disease
Peeking into the “Black Box”
Many risk factors can be quantified through questionnaires,
records, and easily measured attributes (such as blood pressure
and anthropometrics).
The biological mechanism(s) through which these factors
influence disease is not always apparent (i.e., a “black box”).
Value of Mechanistic Insight
Biologic plausibility is a criterion for causality.
Linking lifestyle risk factors with measures of biologic effect
strengthens interpretations of causality.
This linkage, in turn, provides stronger support for
interventions.
55. Why Distinguish Between Molecular and Genetic
Epidemiology?
The basic tenets and principles of molecular and genetic
epidemiology are the same.
However, there are specific features regarding design, analysis
and interpretation inherent in the latter.
3
Definition of Genetic Epidemiology
A discipline that seeks to unravel the role of genetic factors and
their interactions with environmental factors in the etiology of
diseases, using family and population study approaches.

Inherited susceptibility does not mean inherited disease--
environment matters!
When families are studied, the observations (study subjects) are
no longer independent.
This dependence requires special considerations for the analysis
of data.

Genetic Epidemiology is a Method to Answer:
Does a disease cluster in families?
If so, is that clustering likely a result of shared non-genetic risk
factors?
If the clustering is not accounted for by shared lifestyle or
common environment, is the pattern of disease consistent with
inherited effects?
If so, where is the putative gene?

What Diseases or Risk Factors Cluster in Families?
Heart disease
Various cancers
Alcoholism
Others
Epidemiologic Assessment of Clustering
Case-control study
Comparison of the frequency of a positive family history
Expectation under genetic influence
Clustering of “Non-Genetic” Exposures in Families
57. Employment (e.g., several family members with medical
degrees)
Radon from soil
Religious preferences
Lead in paint
Others?
7
Major Point of This Section
You cannot tell easily whether clustering of a risk factor or
disease within a family is due to genetics, culture, or shared
environment (including social or political factors).
Clustering within a family will also occur simply due to bad
luck!
8
Other Correlates of Family History
Large family size
Age of relatives (for an age-related disease)
Gender distribution (consider testicular cancer, prostate disease,
ovarian cysts)
Analysis Approach
58. Model Y (case/control status) = established risk factors.
Add family history variable to denote “genetic” influence (i.e.,
share genes with an individual who has the outcome of interest).
Analysis Issues
Try to compare (and control if necessary) differences between
cases and controls with regard to size of family.
Not easy to adjust for age of family members or their risk
factors.
What types of data can you ask your cases and controls to
provide about their relatives?
Motivation for Case-Control Family Studies
To rule out influence of shared environment, family size
differences, and age on differences in the frequency of family
history between cases and controls
Need to enumerate the relatives of cases and controls, and
determine the disease status and risk factor profile for each
relative
Conduct of Family Studies
Ascertain “probands” (index cases).
Define family (siblings? children? parents? grandparents?)
Invite family members to participate
Collect data (and, typically, biological samples)
How to Select Control Families
Must decide how to identify controls
From spouse’s side of proband’s family?
Or select a random sample from the population?
Will controls be motivated to participate?
Must take HIPAA rules into account
59. Analysis Issues
Exclude the index cases and controls
Model disease (or behavior) of interest based on age, sex,
known risk factors
Evaluate evidence for genetic effect through statistical
significance of variable(s) that indicate “relationship to index
case”
Analysis Issues (cont’d)
Simplest “genetic” variable (1 if relative of case, 0 if relative of
control)
Can also construct indicator variables to designate type of
relative (parent, sibling, more distant relative)
If not significant after including other risk factors, then no
evidence for genetic influence
Evidence of Genetic Influence, so far….
Cases are more likely to have a family history of disease than
controls.
The excess risk to relatives is not accounted for by age, sex, and
other risk factors.
What does that tell us about the underlying genetic influence?
(nothing)
Other Approaches to Identify Genetic Influences
Twin studies
Segregation analysis
Linkage analysis
Twin Studies
60. A “natural experiment” of sorts
Monozygotic (MZ) twins are genetically identical.
Dizygotic (DZ) twins share, on average, the same proportion of
genes as siblings.
Greater concordance (for dichotomous traits) or correlation (for
continuous traits) for MZ than DZ twins is evidence of a genetic
influence.
9
Linkage Analysis
One way to distinguish cultural inheritance from genetic
inheritance is to track a region of our DNA that is transmitted
from parents to offspring in the same manner as the
disease/outcome of interest.
This procedure works well for diseases that follow simple rules
of inheritance (e.g., autosomal dominant or recessive).
10
Segregation Analysis
Historically, linkage analysis required knowledge of the mode
of transmission of the putative gene [dominant versus recessive,
allele frequency, lifetime or age-specific risk (penetrance)].
Segregation analysis has been used to estimate these
parameters.
61. Genetic Epidemiology of Complex Diseases
“Complex diseases” are ones for which the genetic influence
may be modest and environmental factors contribute to disease
risk.
Segregation analysis is not typically done for “complex
diseases.”
Modern approaches ignore models of inheritance (non-
parametric methods).
Use of Epidemiology to Understand Genetic Variation
The methods of genetic epidemiology have been applied
historically to identify genes.
Typically, epidemiologists are not interested in mapping genes,
but rather in figuring out how genes interact with environment
to influence disease risk and outcome.
Molecular Epidemiology
Related individuals are not necessarily required for studies of
the association of genetic variation with risk of disease.
Both cohort and case-control designs can be used.
Because genetic code (germline DNA) is unchanged since
conception, one readily can employ retrospective designs.
Common Strategies for Genetic Marker Selection
Genome-wide approach with anonymous DNA markers
(1,000,000 SNPs on a chip)
SNPs or simple tandem repeat markers in “candidate” genes
based on a priori knowledge about presumed function
SNPs in candidate genes with known functional effect on level
or activity of protein product
62. Primer on Single Nucleotide Polymorphis ms (SNPs)
Because of our redundant genetic code, some SNPs will not
alter the encoded amino acid (e.g., GGA, GGG, GGT and GGC
all encode proline).
SNPs that change an amino acid may not necessarily lead to
change in function of transcribed protein.
More on SNPs
SNPs that don’t change an amino acid may still lead to alternate
splicing of the transcript (and therefore be functionally
important).
SNPs in promoter region may influence level of protein
product–not activity (and therefore be biologically significant).
SNPs in non-coding regions may still have functional effect.
Caveats About SNP Studies
If you’re interested in gene x environment interactions–best to
focus on SNPs with known functional effect.
Human biology is complex: are alterations in one component of
a pathway compensated for by another?
Most SNPs are likely to be modest risk factors–requiring large
sample sizes to determine statistically significant association.
Realistic Expectations
Almost every gene is modified after translation into protein
(e.g., glycosylation, acetylation, methylation).
Thus, the correlation between DNA sequence and protein is far
from perfect.
Most GWAS “hits” are in “gene deserts.”
May be necessary to examine multiple SNPs within a gene and
several genes within a pathway.
63. Molecular Epidemiology – Beyond Genetics
Biomarkers of exposure and disease extend beyond DNA.
Viral or bacterial load
Morphometric analysis of tissues/cells
Hormone or lipid levels in blood or urine
Other examples?
Conclusion
Molecular and genetic epidemiology represent specialty areas of
expertise.
These specialty areas utilize and apply advances in molecular
biology and molecular genetics of disease to:
Unravel disease etiology.
Enable novel approaches for early detection.
Inform more effective interventions by targeting those at
greatest risk.
Chapter 14
Molecular and Genetic Epidemiology
Learning Objectives
Differentiate between molecular and genetic epidemiology
Describe principles of inheritance and sources of genetic
variation
Define epidemiologic approaches for the identification of
genetic components to disease
Peeking into the “Black Box”
Many risk factors can be quantified through questionnaires,
64. records, and easily measured attributes (such as blood pressure
and anthropometrics).
The biological mechanism(s) through which these factors
influence disease is not always apparent (i.e., a “black box”).
Value of Mechanistic Insight
Biologic plausibility is a criterion for causality.
Linking lifestyle risk factors with measures of biologic effect
strengthens interpretations of causality.
This linkage, in turn, provides stronger support for
interventions.
Why Distinguish Between Molecular and Genetic
Epidemiology?
The basic tenets and principles of molecular and genetic
epidemiology are the same.
However, there are specific features regarding design, analysis
and interpretation inherent in the latter.

Case Study:
Telemedicine technology solves healthcare disparity i ssue in
rural Arizona community
Bisbee's Copper Queen Community Hospital implements
successful telemedicine program, drastically reducing cost and
time spent on patient care
Background Founded in 1880, Bisbee is located in the rolling
hills of the Mule Mountains in southeastern Arizona, some 85
miles from Tucson, and within three miles of the border with
Mexico. The region's rich mineral deposits of copper, gold and
silver first attracted miners who hoped to strike it rich. The
town that developed around the mines was named for DeWitt
Bisbee, a San Francisco Judge and investor in the Copper Queen
Mine who, ironically, never set foot in his namesake. Nearly as
old as Bisbee, the Copper Queen Hospital got its start in a mine
tunnel as part of the mining community. Now known as the
Copper Queen Community Hospital (CQCH), it has served the
town for over 125 years. In more recent times, CQCH has
become an acute care critical access hospital for the more than
6,000-plus Bisbee residents and for many of the county's
140,000 residents. The hospital's mission is to maintain and
support access to basic primary healthcare throughout
southeastern Cochise County and to evolve rural health care and
provide patients with the highest quality services.
Challenge Among the primary challenges of CQCH was how to
provide care for patients who needed specialists. For years,
emergency department patients with possible cardiac or stroke
problems had to be transferred to Tucson and Phoenix hospitals
by ambulance, or " in more life- threatening situations " by
helicopter. CQCH patients often discovered after the fact that,
although healthcare was warranted, the expense of emergency
81. transfer was not. "Cardiology disease is the number one killer
of people in rural areas," said CQCH CEO, James Dickson.
"And in Bisbee, we lacked consistent care to treat it. We lacked
access to a cardiologist and to the ongoing maintenance care
required after initial treatment. We decided we needed a way to
solve the physician misdistribution and disease management
problems that occur in a rural area like Bisbee." In 2009, CQCH
received a grant to begin a telemedicine cardiology program.
Dickson set out to find a system that would essentially bring
specialists into Bisbee and CQCH without requiring that they
physically be on site. This would eliminate the costly transfer
of patients to Tucson and Phoenix. It would also minimize the
trauma involved for family members of those being transported
far distances. Overall, the implementation of a telemedicine
program would shrink the disparity in healthcare experienced by
the people of Bisbee by making specialists vastly more within
reach without the price tag of on site consultations.
Solution
Dickson and CQCH worked with telemedicine solutions
provider, GlobalMed, to build a tele- cardiology system using
GlobalMed's i8500 Series Mobile Video Cart. The wireless,
telemedicine videoconferencing system includes EasyShare
videoconferencing technology that uses the public Internet,
enabling specialists to visit with patients on a virtual basis. It
also includes a large, flat-panel touch screen PC for fast
communications, as well as a high quality camera providing
remote pan, tilt and optical zoom. Currently in the first phase of
82. its tele-cardiology program, CQCH has connected its system
and those of other, small Cochise County hospitals with the
larger Tucson medical centers. From December 2009 to June
2010, 36 patients in the Emergency Department with suspected
heart problems required cardiology consultation. Using the
Mobile Telemedicine Cart equipped with a digital stethoscope,
healthcare providers in Bisbee were able to provide
cardiologists in Tucson with the ability to see and speak to the
patients in real-time, hear their heart sounds clearly and review
their electro-cardiograms via fax at the same time. These
consultations confirmed that only nine of the 36 patients needed
transport by ambulance or helicopter to another facility. The 27
patients who stayed in Bisbee were discharged from CQCH with
prescriptions and/or heart monitors. The cost savings to patients
and insurers was approximately $540,000 based on a $10,000
transfer cost and an additional $10,000 hospital stay per patient
who instead had their care provided by CQCH and were able to
remain in Bisbee. "The cost savings patients see as a result of
the remote consultations is immense", said Dickson. "The cost
for a helicopter transport is between $10,000 and $12,000.
Additionally, the cost for treatment in a Tucson hospital is
roughly $10,000 more per visit than it is here in Bisbee. So
we're looking at a savings of about $20,000 per patient just by
having the ability to consult with a specialist remotely, utilizing
the telemedicine system, instead of having to be on-site where
83. the doctor is.
Results Dickson points to one case in particular as a perfect
example of what tele-cardiology means to the town of Bisbee.
An 81-year old man arrived at CQCH with apparent atrial
fibrillation. A Tucson cardiologist saw the patient via video-
conference, listened to his heart sounds and studied his EKG
before determining that there was no need to move him to
Tucson. The patient was admitted to CQCH, treated overnight
and was discharged the next day with a halter monitor. In his
case, the patient was spared an unnecessary transfer to a facility
two hours away. He also avoided having to experience a lengthy
hospital stay, as well as the hefty hospital bill for services that
weren't needed. CQCH had similar success after partnering with
Mayo Clinic Scottsdale for its tele-stroke program. More than
three years ago, the Mayo Clinic started the Stroke
Telemedicine Program for Arizona Rural Residents with a grant
from the Arizona Department of Health Services. Medical
studies have shown that stroke victims face a three-hour
window in which the initiation of Tissue Plasminogen
Activator, or TPA, can mean the difference between recovery
and permanent paralysis. The phrase used in stroke programs is
"Time is Brain." Jack Porter, the Mayor of Bisbee, can testify to
TP A effectiveness. When Porter appeared to have suffered a
stroke, he went to the CQCH. A telemedicine consultation with
a Mayo neurologist in Scottsdale less than a half hour later
84. confirmed the stroke diagnosis, and he ordered that Porter be
started on a course of TPA. The timely treatment prevented any
lasting debilitating effects, and Porter continues to lead the
town as its mayor. When other rural hospitals in Cochise
County recognized the advantages of telemedicine, they and
CQCH formed the Southeast Arizona Telemedicine Association,
or SATA, which includes the following hospitals: Northern
Cochise Community Hospital in Willcox, Benson Community
Hospital, Mount Graham Regional Medical Center in Safford
and Southeast Arizona Medical Center in Douglas. Dickson says
his hospital has not cut care in the wake of rising healthcare
costs, but rather has increased it by making it more efficient.
"By not having the transportation fees and the excessive cost of
re-evaluation at another hospital, we have really spawned a cost
reduction and quality increase in the delivery system," Dickson
says. "Given our success with telemedicine at CQCH, I envision
a virtual hospital in every rural area in America in the near
future so that people will have the care they need and so that
physician misdistribution becomes a problem of the past."
