Dr Oxley and Dr Hartman take their Individual Health Exposure Risk Profile (IEHRP) and scale to meet the needs for Veterans and Military member by creating a mathematical process to combine clinical and social determinants into "one" risk profile for clinical and policy uses to identify and reduce the stressors of military transition into public life. What's more impressive is their novel mathematical process/approach can be used for several complex issues, such as, financial service creating an individual investment profile or portfolio for retail and institutional investors.

This paper introduces the Service member Veteran Risk Profile (SVRP), a mathematical process/solution to quantitatively represent transitioning Service member (TSM) and/or Veteran quality of life risks by integrating clinical and social determinant data into an individual risk profile. The SVRP creates, for the first time, a mechanism for the Department of Defense (DoD) and Department of Veterans Affairs (VA) to holistically represent the challenges of military members transitioning into civilian life that can lead to negative outcomes and proactively identify transitioning Service members and Veterans at risk. More importantly, the SVRP supports clinical and non-clinical modalities to reduce the negative impacts of transition and beyond for TSM and Veterans. Lastly, the SVRP can be displayed through user-friendly visualizations so DoD/VA policymakers and decision-makers can make more informed policy and resource decisions to improve TSM/Veteran overall quality of life.

Introduction
The scenario I will be working with is that I am working at NCLEX Memorial Hospital in the infectious disease unit. As a healthcare professional, I need to work to improve the health of individuals, families and communities in various settings. The current situation that has posed as a problem at the hospital and raised eyebrows is that in the past few days, there has been an increase in patients admitted with a particular infectious disease. The basic statistical analysis shows that the disease does not affect minors hence the ages of the infected patients does play a critical role in the method that shall be required to treat the patients in order to impact positively on the health and well-being of the clients being served whether infected with the disease or associated with those infected. After speaking to the manager, we decided that we shall work together in utilising the available statistical analysis to look closer into the ages of the infected patients. To do that, I had to put together a spreadsheet with the data containing the information we shall need to carry out the analysis.
Data Analysis
From the data collected and input on an Excel sheet, there are sixty patients with the infectious disease. Of the patient’s whose data has already been collected an input on the excel sheet, the ages range from thirty-five years of age to seventy-six. There is only one patient in their thirties with the age of thirty-five. There are five patients in their forties, One forty-five, one forty-six, two at forty-eight and two at forty-nine. There are fifteen patients in their fifties, two at fifty, one fifty-two, one fifty-three, one fifty-four, four at fifty-five, one fifty-six, one at fifty-eight and four at fifty-nine. There are twenty-three patients in their sixties, five at sixty, one at sixty-two, one at sixty-three, two at sixty-four, one at sixty-five, three at sixty-eight and seven at sixty-nine. Finally, we have fifteen infected patients in their seventies, six at seventy, three at seventy-one, three at seventy-two, one at seventy-three, one at seventy-four and one at seventy-six. From the graph in Figure 1 below, the horizontal axis depicts the age group of patients infected with the disease and the vertical axis depicts the number of patients in the age group infected with the disease.

Analytic Studies
There are basically two types of studies: experimental and observational. In an experimental study, the exposure has not occurred yet. The investigator controls the exposure in the study groups and studies the impact. For example, he may immunize one group with an experimental vaccine that has been developed for a disease and compare the frequency with which the disease develops to the control group (which had no modification). In an observational study, the exposure has already occurred. The exposures and outcomes are observed and analyzed, not created experimentally. Observational studies are often more practical and continue to provide the major contribution to our understanding of diseases. There are two main types of observational studies: cohort (prospective) and case-control (retrospective) studies.
In a cohort study, a group of people who share a common experience within a defined time period (cohort) are categorized based upon their exposure status. For example, individuals at a work place where an asbestos exposure occurred would be considered a cohort. Another example would be individuals attending a wedding where a foodborne illness occurred. Cohort studies have well-defined populations. Often, cohort studies involve following a cohort over time in order to determine the rate at which a disease develops in relation to the exposure.
In a cohort study, relative risk is used to determine whether an association exists between an exposure and a disease. Relative risk is defined as ratio of the incidence rate among exposed individuals to the incidence rate among unexposed individuals.
To calculate the relative risk, you would use the following formula: (a/a+b) / (c/c+d) where:
a = the number of individuals with a disease who were exposed.
b = the number of individuals without a disease who were exposed.
c = the number of individuals with a disease who were NOT exposed.
d = the number of individuals without a disease who were NOT exposed.
In a case-control study, the sample is based upon illness status, rather than exposure status. The researcher identifies a group of people who meet the case definition and a group of people who do not have the illness (controls). The objective is to determine if the two groups differ in the rate of exposure to a specific factor or factors.
In contrast to a cohort study, the total number of people exposed in a case-control study is unknown. Therefore, relative risk cannot be used. Instead, an odds ratio or risk ratio is used. An odds ratio measures the odds that an exposed individual will develop a disease in comparison to an unexposed individual. Please click the button below to learn how to calculate an odds ratio.

a = the number of individuals with a disease who were exposed.

Frequency Measures Used in Epidemiology
Introduction
In epidemiological studies, many qualitative variables have only two possible categories, such as
Alive or dead
Case or control
Exposed and unexposed
The frequency measures for dichotomous variable include:
Ratio
Proportion
Rate
( All the above 3 measure are based on the same formula: )
Ratios, Proportion, and Rates Compared
In a ratio, the values of x and y may be completely independent from each other or x is a part of y
For example , the gender of the children attending a specific program could be compared in one of the following ways:
Proportion is a ratio in which X is included in Y
For example , the gender of the children attending a specific program
Rate is a proportion that measures the occurrence of an event in a population over time
Rate = X
Ratios, Proportion, and Rates Compared

Analytic epidemiology is defined as the study of the determinants of disease or reasons for relatively high or low frequency in specific groups. Analytic epidemiology answers questions regarding why the rate is high or low in a particular group. Observations of differences lead to formation of hypotheses.

ABSTRACT
In day-to-day life, we are continuously exposed to different kinds of risk.
Unfortunately, avoiding risk can often come at societal or individual
costs. Hence, an important task within risk management is deciding
how much it can be justified to expose members of society to risk x in
order to avoid societal and individual costs y – and vice versa. We can
refer to this as the task of setting an acceptable risk threshold. Judging
whether a risk threshold is justified requires normative reasoning about
what levels of risk exposure that are permissible. One such prominent
normative theory is utilitarianism. According to utilitarians, the preferred
risk threshold is the one that yields more utility for the most people
compared to alternative risk thresholds. In this paper, I investigate
whether and the extent to which utilitarian theory can be used to nor-
matively ground a particular risk threshold in this way. In particular, I
argue that there are (at least) seven different utilitarian approaches to
setting an acceptable risk threshold. I discuss each of these approaches
in turn and argue that neither can satisfactorily ground an acceptable
risk threshold.

In day-to-day life, we are continuously exposed to different kinds of risk. These risks may range
from the longer-term and potentially life threatening, such as climate change, to the mundane,
such as catching the flu or being involved in a car accident. Unfortunately, avoiding risk can
often come at societal or individual costs. We may, for example, restrict access to public areas
during a disease outbreak or impose mass surveillance measures to prevent terrorist attacks.
Hence, an important task within risk management is deciding how much it can be justified to
expose members of society to risk x in order to avoid societal and individual costs y – and vice
versa. We can refer to this as the task of setting an acceptable risk threshold. Judging whether a
risk threshold is justified requires normative reasoning about what levels of risk exposure that
are permissible. One such prominent normative theory is utilitarianism. Utilitarians hold that pref-
erable action in a certain situation is the one that maximizes the most utility for the most peo-
ple. Hence, according to utilitarians, the preferred risk threshold is the one that yields more
utility for the most people compared to alternative risk thresholds.
Although the cost-benefit calculus of utilitarianism has often been invoked within risk man-
agement and assessment (Guehlstorf 2012, 45–47), little philosophical literature has investigated
whether utilitarianism can be applied to the task of setting an acceptable risk threshold.

Author Notes
This paper is being submitted on February 26, 2017 for Juton Hemphill’s Inferential Statistics and Analytics course.
In the statistical inference, the main aim is to estimate the populations’ parameters by the use of samples that have been drawn from that population.
There is thus the need to create a confidence interval. It gives the range values that have a chance of including unknown parameters from the population from the sample drawn (2017). Simply this means that when drawing an inference from a sample taken we have the estimate of the population parameter and the margin of error which means there is a chance of inclusion of unknown population parameter, the estimated range being calculated from a given set of sample data (DG, 2017).
The point estimate of a population parameter is a single value used to estimate the population parameter. For example, the sample mean x is a point estimate of the population mean μ. Point estimation is defined as the process by which the estimation of parameters from a normal probability distribution that is based on the data that is observed from a particular population.
The mean is the best point estimator. It is because the mean in a normal distribution is the average of the data set and normally the center of the data. It is where most of the items in the population lie and usually represent the data set. For all populations, the sample mean x is an unbiased estimator of the population mean µ, meaning that the distribution of sample means tends to center about the value of the population mean µ. For most populations, the distribution of sample means x is always more consistent (with less variation) than the distributions of other sample statistics.
The confidence interval that is created from a range based on a confidence level and useful in the estimating the actual population values based on the normal distribution for a statistic of that population. It is useful to accommodate a range of estimates and reduce chances of avoiding of misinterpretation of non-significant results of small studies ("Point Estimates and Confidence Intervals", 2017).
Since the best point estimator of the population means is the sample mean x is a point estimate of the population mean μ then for our data, then the Mean = 3705 / 60 = 61.81667 is the best.

From our study of the patients infected with the infectious disease in NCLEX Memorial Hospital is that at 95% confidence interval the mean lies between 59.26 < x < 64.38.

The Personalized Health Risk Profile: A New Tool for Safety and Occupational ...Richard Hartman, Ph.D.
This presentation introduces the Personalized Risk Health Profile (PRHP), a mathematical process to quantitatively evaluate personalized health risks by integrating workplace, lifestyle, and environmental exposure (the root cause of disease) data from traditional and new personal monitoring technologies combined with individual health histories and genomic data to provide a new and novel capability for the safety and health professionals and policymakers. The PRHP creates for the first time a mechanism to better understand the relationships between a worker's health, genetic predispositions, and exposures through mathematical expression and process, ultimately providing a modern tool to better understand the effects of exposures from the workplace, environment, as well as day-to-day activities. More importantly, the PRRP displays individual and population risks through user-friendly visualizations bridging the gap between "Population Health" and "Personalized Medicine" so safety and health professionals can recommend data-driven interventions to mitigate individual risks to improve health/performance, and policymakers and decision-makers can make more informed policy and resource decisions.

Part 1, which appeared in the February 2012
issue, introduced the concept of confidence
intervals (CIs) for mean values. This article
explains how to compare the CIs of two mean
scores to draw a conclusion about whether or
not they are statistically different. Two mean
scores are said to be statistically different if their
respective CIs do not overlap. Overlap of the CIs
suggests that the scores may represent the same
"true" population value; in other words, the true
difference in the mean scores may be equivalent

Frequency Measures Used in Epidemiology
Introduction
In epidemiological studies, many qualitative variables have only two possible categories, such as
Alive or dead
Case or control
Exposed and unexposed
The frequency measures for dichotomous variable include:
Ratio
Proportion
Rate
( All the above 3 measure are based on the same formula: )
Ratios, Proportion, and Rates Compared
In a ratio, the values of x and y may be completely independent from each other or x is a part of y
For example , the gender of the children attending a specific program could be compared in one of the following ways:
Proportion is a ratio in which X is included in Y
For example , the gender of the children attending a specific program
Rate is a proportion that measures the occurrence of an event in a population over time
Rate = X

Analytic epidemiology is defined as the study of the determinants of disease or reasons for relatively high or low frequency in specific groups. Analytic epidemiology answers questions regarding why the rate is high or low in a particular group. Observations of differences lead to formation of hypotheses.
Analytic Studies
There are basically two types of studies: experimental and observational. In an experimental study, the exposure has not occurred yet. The investigator controls the exposure in the study groups and studies the impact. For example, he may immunize one group with an experimental vaccine that has been developed for a disease and compare the frequency with which the disease develops to the control group (which had no modification). In an observational study, the exposure has already occurred. The exposures and outcomes are observed and analyzed, not created experimentally. Observational studies are often more practical and continue to provide the major contribution to our understanding of diseases. There are two main types of observational studies: cohort (prospective) and case-control (retrospective) studies.
In a cohort study, a group of people who share a common experience within a defined time period (cohort) are categorized based upon their exposure status. For example, individuals at a work place where an asbestos exposure occurred would be considered a cohort. Another example would be individuals attending a wedding where a foodborne illness occurred. Cohort studies have well-defined populations. Often, cohort studies involve following a cohort over time in order to determine the rate at which a disease develops in relation to the exposure.
In a cohort study, relative risk is used to determine whether an association exists between an exposure and a disease. Relative risk is defined as ratio of the incidence rate among exposed individuals to the incidence rate among unexposed individuals.
To calculate the relative risk, you would use the following formula:
(a/a+b) / (c/c+d)
where:
a = the number of individuals with a disease who were exposed.
b = the number of individ.

ABSTRACT
In day-to-day life, we are continuously exposed to different kinds of risk.
Unfortunately, avoiding risk can often come at societal or individual
costs. Hence, an important task within risk management is deciding
how much it can be justified to expose members of society to risk x in
order to avoid societal and individual costs y – and vice versa. We can
refer to this as the task of setting an acceptable risk threshold. Judging
whether a risk threshold is justified requires normative reasoning about
what levels of risk exposure that are permissible. One such prominent
normative theory is utilitarianism. According to utilitarians, the preferred
risk threshold is the one that yields more utility for the most people
compared to alternative risk thresholds. In this paper, I investigate
whether and the extent to which utilitarian theory can be used to nor-
matively ground a particular risk threshold in this way. In particular, I
argue that there are (at least) seven different utilitarian approaches to
setting an acceptable risk threshold. I discuss each of these approaches
in turn and argue that neither can satisfactorily ground an acceptable
risk threshold.

In day-to-day life, we are continuously exposed to different kinds of risk. These risks may range
from the longer-term and potentially life threatening, such as climate change, to the mundane,
such as catching the flu or being involved in a car accident. Unfortunately, avoiding risk can
often come at societal or individual costs. We may, for example, restrict access to public areas
during a disease outbreak or impose mass surveillance measures to prevent terrorist attacks.
Hence, an important task within risk management is deciding how much it can be justified to
expose members of society to risk x in order to avoid societal and individual costs y – and vice
versa. We can refer to this as the task of setting an acceptable risk threshold. Judging whether a
risk threshold is justified requires normative reasoning about what levels of risk exposure that
are permissible. One such prominent normative theory is utilitarianism. Utilitarians hold that pref-
erable action in a certain situation is the one that maximizes the most utility for the most peo-
ple. Hence, according to utilitarians, the preferred risk threshold is the one that yields more
utility for the most people compared to alternative risk thresholds.
Although the cost-benefit calculus of utilitarianism has often been invoked within risk man-
agement and assessment (Guehlstorf 2012, 45–47), little philosophical literature has investigated
whether utilitarianism can be applied to the task of setting an acceptable risk threshold.

Author Notes
This paper is being submitted on February 26, 2017 for Juton Hemphill’s Inferential Statistics and Analytics course.
In the statistical inference, the main aim is to estimate the populations’ parameters by the use of samples that have been drawn from that population.
There is thus the need to create a confidence interval. It gives the range values that have a chance of including unknown parameters from the population from the sample drawn (2017). Simply this means that when drawing an inference from a sample taken we have the estimate of the population parameter and the margin of error which means there is a chance of inclusion of unknown population parameter, the estimated range being calculated from a given set of sample data (DG, 2017).
The point estimate of a population parameter is a single value used to estimate the population parameter. For example, the sample mean x is a point estimate of the population mean μ. Point estimation is defined as the process by which the estimation of parameters from a normal probability distribution that is based on the data that is observed from a particular population.
The mean is the best point estimator. It is because the mean in a normal distribution is the average of the data set and normally the center of the data. It is where most of the items in the population lie and usually represent the data set. For all populations, the sample mean x is an unbiased estimator of the population mean µ, meaning that the distribution of sample means tends to center about the value of the population mean µ. For most populations, the distribution of sample means x is always more consistent (with less variation) than the distributions of other sample statistics.
The confidence interval that is created from a range based on a confidence level and useful in the estimating the actual population values based on the normal distribution for a statistic of that population. It is useful to accommodate a range of estimates and reduce chances of avoiding of misinterpretation of non-significant results of small studies ("Point Estimates and Confidence Intervals", 2017).
Since the best point estimator of the population means is the sample mean x is a point estimate of the population mean μ then for our data, then the Mean = 3705 / 60 = 61.81667 is the best.

The Personalized Health Risk Profile: A New Tool for Safety and Occupational ...Richard Hartman, Ph.D.
This presentation introduces the Personalized Risk Health Profile (PRHP), a mathematical process to quantitatively evaluate personalized health risks by integrating workplace, lifestyle, and environmental exposure (the root cause of disease) data from traditional and new personal monitoring technologies combined with individual health histories and genomic data to provide a new and novel capability for the safety and health professionals and policymakers. The PRHP creates for the first time a mechanism to better understand the relationships between a worker's health, genetic predispositions, and exposures through mathematical expression and process, ultimately providing a modern tool to better understand the effects of exposures from the workplace, environment, as well as day-to-day activities. More importantly, the PRRP displays individual and population risks through user-friendly visualizations bridging the gap between "Population Health" and "Personalized Medicine" so safety and health professionals can recommend data-driven interventions to mitigate individual risks to improve health/performance, and policymakers and decision-makers can make more informed policy and resource decisions.

The presentation will introduce the Individual Exposure Health Risk Profile (IEHRP), a novel approach that integrates occupational, lifestyle, and environmental exposure data from traditional and new personal monitoring exposure assessment technologies with clinical and genomic data to provide a new and novel capability for personalized health. We will demonstrate how IEHRP will create unique opportunities to shift from a healthcare delivery system dependent heavily on infrastructure and staffing to one that allows individuals to take ownership of their health and drive their behaviors and health-related choices by leveraging a Big Data infrastructure and advanced analytics.
ABSTRACT
This paper will introduce the origins and demonstrate how the concept and implementation of Total Exposure Health (TEH) is ushering in a bold solution to capture workplace, environmental, and lifestyle exposures to the individual using advances in science, technology, and informatics.
It will also introduce and describe the power behind Total Exposure Health, which is a mathematical process to quantitatively evaluate individual health risks based on genetics, occupational, lifestyle, and environmental exposures, medical disposition, protective factors, etc., forming the Individual Exposure Health Risk Profile (IEHRP).

The mandate to establish an office of Rural Health was ORH was mandated in 2006 by Public Law 109-461, section 212, to improve care and access for veterans who reside in rural areas of the united states.
Applying the 360° Approach, Dr. Hartman was able to look at the ORH from all aspects to develop policy and strategicdirection for enhancing services to Veterans who reside in rural and highly rural areas. His vision outlined in the graphic has set six strategic goals and articulated a number of objectives to meet thesegoals to ensure improved quality and access of health care service delivery to less populous areasof the United States and was implemented in 2009 and retains to date.
As global IH/OH professionals, we are positioned to effectively contribute as exposure scientists not only to the occupational health of individuals but to their overall well-being. This education session will demonstrate how the United States Air Force is ushering in a bold solution to capture workplace, environmental, and lifestyle exposures to the individual using advances in science, technology, and informatics called Total Exposure Health (TEH). TEH provides a framework and tools to strengthen prevention and reduce illness and injury through effective early intervention, improved health-related risk assessment decision-making, and risk mitigation. Individual Exposure Health Risk Profiles (IEHRP) attempt to quantitatively evaluate individual health risks based on genetics, occupational, lifestyle, and environmental exposures, medical disposition, protective factors,etc. Participants will have a new view of population-based standards and will explore the potential future of individual occupational exposure standards.

Total Exposure Health - A Bold Approach to Transform the Delivery of Healthca...Richard Hartman, Ph.D.
As the medical consumer becomes more informed, as science and technology improve, and as it becomes clear that one size medicine does not fit all, the healthcare delivery system needs a significant paradigm shift from its primary focus on disease and injury treatment to a holistic approach to health and prevention. To meet this emerging demand, the Air Force Medical Service (AFMS) created Total Exposure Health (TEH), which associates human exposures to the lowest common denominator – the individual’s DNA (N=1) – to enrich clinical decisions with a forward vision using the advancements in science, technology, medicine, and informatics.
Exposure means different things to different people, so we conveniently packaged TEH into a simple brand. We revealed TEH as a catalyst to move exposure health away from animal data and population models to individual personalized effects of exposure. We also found TEH fosters innovations in research and technology development through programmatic support and can promote economic development, particularly in science, technology, engineering and mathematics (STEM).

Combining Clinical and Social Determinants to Improve Military/Veteran Quality of Life
1. Combining Clinical and Social Determinants to
Improve Military/Veteran Quality of Life
Abstract—This paper introduces the Service mem-
ber Veteran Risk Profile (SVRP), a mathematical pro-
cess/solution to quantitatively represent transitioning Ser-
vice member (TSM) and/or Veteran quality of life risks
by integrating clinical and social determinant data into
an individual risk profile. The SVRP creates, for the first
time, a mechanism for the Department of Defense (DoD)
and Department of Veterans Affairs (VA) to holistically
represent the challenges of military members transitioning
into civilian life that can lead to negative outcomes and
proactively identify transitioning Service members and
Veterans at risk. More importantly, the SVRP supports
clinical and non-clinical modalities to reduce the neg-
ative impacts of transition and beyond for TSM and
Veterans. Lastly, the SVRP can be displayed through
user-friendly visualizations so DoD/VA policymakers and
decision-makers can make more informed policy and
resource decisions to improve TSM/Veteran overall quality
of life.

I. MOTIVATION
Recent research suggests transition from active duty
to civilian life is one period of stress that has critical
impact on the future functioning and quality of life of the
Veteran [1]. These transition challenges are associated
with negative outcomes, such as, homelessness, suicide
ideation, and first episode psychosis [2].
To address the potential negative outcomes of transi-
tion, Department of Defense (DoD) and Department of
Veterans Affairs (VA) clinicians currently rely heavily
on clinical determinants to assess transitioning Service
member (TSM)/Veteran health and clinical treatments to
mitigate negative outcomes, even though there are many
risk factors beyond the clinical determinants of health
that contribute to the aforementioned negative outcomes
[3].
To help stem the increased prevalence of negative
outcomes associated with transition to civilian life, such
as suicide [5], in the age of informatics and Big Data,
DoD and VA needed a way to identify, collate, and
address the complexities associated with military to civil-
ian transition and mitigate the negative outcomes from
transition to civilian life: a novel approach combining
clinical and social determinant data into insight and
ultimately action.
To respond to this need, a mathematical pro-
cess/solution was developed that not only integrated clin-
ical and social determinants but provided the DoD/VA
with a process for clinicians, social benefits advisors,
and decision makers that could: 1) identify the factors
associated with negative outcomes, such as suicide,
homelessness, unemployment, and financial strain into a
single quantitative risk, 2) provide clinical and/or social
service mitigation strategies to address TSM/Veteran
risks and 3) aggregate individual TSM/Veteran data into
population formats to inform decision makers on key
policy and resource decisions. Furthermore, they needed
a dynamic approach that could evolve with advances in
sciences and informatics. This new approach is called
the Service member Veteran Risk Profile (SVRP).
II. DERIVATIONS
The SVRP leverages advances in the clinical and
social sciences and informatics allowing data scientist
to integrate disparate and unstructured data from both
clinical and nonclinical data sources and account for
the many factors that contribute to negative outcomes
TSM/Veterans face associated with transition to civil-
ian life [6]. The SVRP provides clinicians and social
service providers the ability to visualize and quantify a
transitioning Service member or Veteran risks beyond
any one variable. This new methodology, when applied,
turns multiple sources of clinical and social determinant
data into actionable insight for healthcare/social benefits
professionals through a holistic risk profile.
Richard T. Hartman Mark E. Oxley
2. This holistic risk profile first required the development
of a mathematical expression (i.e., equation), and pro-
cesses so the disparate and unstructured data collected
from clinical and non-clinical records could be merged
into a numerical representation of an individual’s overall
risk from negative outcomes.
To build the SVRP, our initial mathematical expression
was created based on a single notional negative outcome
with a set of three notional factors that could contribute
to the overall negative outcome. This is expressed as the
Service member Veteran Risk Index (SVRI).
SVRI1 = v1,1 + v1,2 + v1,3. (1)
Here v1,1 is the value of the individual’s poverty
status. The value v1,2 is the same individual 1, and the 2
represents the unemployment status. The v1,3 is also the
same individual 1, and 3 represents the clinical effect per
the evidence in the individual’s medical record (clinical
history).
To account for more than one negative outcome, we
simply combined several negative outcomes or Service
member Veteran Risk Indices (SVRIs) to create the
SVRP, which is expressed as a column vector [7].
SVRP =
SVRI1
.

SVRIM
. (2)
The M is a generic, fixed integer denoting that there are
M indices or negative outcomes in this profile.
A. Classifier Function for the SVRP
Generating an overall numerical and/or visual repre-
sentation of risk necessitated the creation of a risk value,
that is, a numerical value for each variable vm,n within
the SVRP. The lower case m is a variable representing
an individual negative outcome, such as homelessness,
suicide ideation, etc., and the lower case n represents
confounding factors associated with that risk, such as,
poverty status, medical condition, etc. That is, if the
confounding factor for the negative outcome of the
individual was determined to be “at risk” or “not at risk”
then the corresponding numerical values for vm,n would
be either 1 or 0, respectively.
For example, let us begin with a generic risk value
and conclude with a single risk when compared to a risk
threshold. Suppose there is a test T related to a risk,
and this test is performed on the individual, h. Suppose
the output of the test is a single numerical value, r,
called the test measurement value. Since test T, acting
on individual, h, yields the value, r, then we will write
it in function notation as T(h) = r.
We seek a classifier C whose input is the test mea-
surement value r and output is a risk value v, that is,
a real number. The possible values for r could be any
real number that is compared to a threshold value where
an ri to the threshold yields a v = 1 and an threshold
yields a v = 0, that is, v ∈ [0, 1].
The classifier C should be a function such that C(r) =
v. Notice that composing the test function T with the
classifier function C, applied to v ∈ {0, 1} for individual
h, yields the risk value v. That is, C(T(h)) = v.
Many classifiers are often simplified such that the
risk values are either 1 or 0, where the value v = 1
corresponds to the label “at risk” and the value v = 0
corresponds to the label “not at risk”.
There are many tests where the classifier C already
exists as an established classifier based upon studies with
data from a population of individuals, such that some
threshold value θ, exists (that is, a real number called
the standard threshold value) and is defined to be
v = C(r) =
0 if r θ
1 if r ≥ θ
. (3)
For some tests the measurement values presented to
the classifier could be defined such that
v = C(r) =
1 if r θ
0 if r ≥ θ
. (4)
A practical example of interest is Suicide Ideation (SI).
For example, when evaluating SI, (1) becomes
SVRI(SI) = v(SI,poverty status) + v(SI,employment status)+
v(SI,medical history) (5)
The threshold for poverty status, according to the US
Department of Health and Human Service (DHHS), is
$12,060 for a single person in family/household [8].
Therefore, the classifier function for the poverty status
measurement r1,1 with a threshold value of $12,060 is
v1,1 = C(r1,1) =
1 if r1,1 $12, 060
0 if r1,1 ≥ $12, 060
. (6)
Hence, if the measured value r1,1 of the poverty status
was less than $12,060 then the variable v1,1 would be
recorded as 1, and if the measured value r1,1 of the
poverty status was greater than or equal $12,060, then
the variable v1,1 would be recorded as 0.
Recognizing not all SVRI variables, v, can be defined
by (3) and (4), it became evident that an additional
3. generic classifier function was needed for v when no
validated/credible threshold value, θ, existed. This new
classifier function based on presence/absence can be
expressed as:
v = C(r) =
1 if r = presence
0 if r = absence
. (7)
Where r may or may not be a numerical value, that is,
if r = “present,” then v = 1 and if r 6= “present,” then a
v = 0, that is v ∈ {0, 1}. For example, when evaluating
SI and the risk factor v1,2 associated with unemployment
status, we know that unemployment can be detrimental
to mental health and is associated with increased risk of
suicide [8].
That is, if a transitioning Service member or Veteran is
unemployed, they are at increased risk of SI. Therefore,
the classifier function for the presence/absence of the
unemployment associated to SI r1,2 is
v1,2 = C(r1,2)
=
1 if r1,2 = presence unemployment
0 if r1,2 = absence unemployment
(8)
Hence, if the unemployment r1,2 is present then the
variable v1,2 would be recorded as 1, and if the unem-
ployment r1,2 is absent then then the variable v1,2 would
be recorded as 0.
With the classifier functions developed to populate
the variables v1,1, v1,2, v1,3 for (1) then the SVRI can
produce a meaningful value of risk, and recognizing
the SVRP as a combination of SVRIs for an individual
transitioning Service-member or Veteran, then (2) can
now be expressed as
SVRP =
SVRI1

to account for multiple exposures, where vm,1 is now
vM,1 after the conversion of the raw data m to the
classifier result M.

III. EXTENSION OF MULTIPLE DETERMINANTS OF
THE SVRP
With the SVRP equipped to address multiple nega-
tive outcomes like homelessness and/or suicide, the
limitations to the SVRI become evident. This required
the SVRI to be modified so it could account for multiple
confounding factors, (Figure 1), such as family history,
health access, and education, and is represented by (10)
with (N) confounding factors or determinants [6].

A. Visualization and Normalization of the SVRP
To visualize the SVRP, let us assume we have an
SVRP for an individual with four separate negative
outcomes. Applying classifier functions to notional raw
data for every rm,n we get the following values for each
vm,n in the matrix array, where the SVRP is expressed
4. as a column vector.
SVRP = (11)
=
SVRI1
.

and represented visually in Figure 2.
Fig. 2. Visualizing SVRP using notional raw data for an individual
transitioning Service member/Veteran.
To ensure each SVRP could be represented in a
common scale for future comparison it became necessary
to normalize the output of (11) such that each SVRI was
displayed between 0 and 1. This resulted in the following
equation:
SVRP = (12)
=
SVRI1
.
.
.
SVRIM

Simplifying the notation by observing the different
factors form their own matrices. We rewrite (12) as:
SVRP = (13)
=
SVRI1
.
.
.
SVRIM
=
(
v1,1 · · · v1,N
.
.
.
...
.
.
.
vM,1 · · · vM,N
6. denotes the Hadamard product of
two matrices with the same size [10]. Therefore, the
SVRP in its simplest form is
SVRP = [V
7. NF] 1 (14)
where
V =
v1,1 · · · v1,N
.
.

, and

Using data from the previous example in conjunction
with (13), results in the following computation where

9. B. Censored Data
Recognizing there may be instances where raw data
may be not available (e.g., no financial data, missing or
lost medical records, etc.), the issue of censored data
became evident, since one could not assume a missing
value is 1 or 0 with confidence. This issue can be easily
demonstrated by replacing the 0’s in (16) with dashes,
where (-) is censored data resulting in:
SVRP = (17)

ual.
This modification was necessary to properly visualize
the data in order to identify and prioritize risks for future
clinical decision-making when data is not available as
can been seen in the difference between Figures 3 and 4
where the censored data example produces significantly
higher risks for all SVRI’s than the original example.
With the development of (10) and a process to vi-
sualize risks based on multiple exposures with multiple
variables, two key questions still needed to be addressed:
1) Which variable vm,n was the most important?
That is, should some variable(s) weigh more than
others?
2) How do we account for the variability of each
variable?
C. Correction and Weighting Factors
To answer the first question (e.g., is employment
more important than medical history?), the equation
was enhanced with a multiplicative “Weighting Fac-
tor”, WFm,n, a numerical value that would account for
importance of each variable, vm,n. To account for the
variability (confidence), the equation included a multi-
plicative “Correction Factor”, CFm,n, a numerical value
that would address the variability of each variable based
on the confidence in the process, procedures, methods,
device, etc. for each vm,n. Combining the CF with the
WF resulted in the following iteration of the SVRP:
SVRP =
SVRI1

and simplifying the notation by observing the different
factors from their own matrices. That is,

where V is the matrix of the risk values, NF is the matrix
for the normalization factor values, CF is the matrix for
the corrections factors values, WF is the matrix for the
weighting factors values, and 1 is the column vector of
18. all ones. Note that the SVRP in its simplest form, can
be visualized as in prior examples/figures, however, to
represent (20) numerically required a process to convert
the resulting column vector to a number.
IV. NUMERICAL REPRESENTATION OF THE SVRP
To represent the SVRP numerically, one way is to av-
erage the SVRIs. Assume there are M negative outcomes
then:
avg(SVRP) =
1
M
M
X
m=1
SVRIm. (21)
Applying this to the previous example (see (17) and
Figure 3) then:
avg(SVRP) =
1
4
4
X
m=1
SVRIm (22)
=
1
4
(1 + 0.66 + 0.66 + 0.33)
= 0.6625
is the overall risk for the individual with the ability to
represent the SVRP numerically so healthcare and/or so-
cial benefits providers can now use a numerical value for
an individual transitioning Service member or Veteran’s
overall risk between 0 and 1, which could be represented
as:
0 avg(SVRP) 0.25 ⇒ Low Risk (23)
0.25 ≤ avg(SVRP) 0.75 ⇒ Med Risk
0.75 ≤ avg(SVRP) ≤ 1.00 ⇒ High Risk
For example, the individual in (22) would be rated
at medium risk. Therefore, with a gauge of overall
individual risk, the DoD/VA clinicians and/or social
benefits advisors can easily triage multiple individuals al-
lowing the organization or the healthcare/social benefits
provider to prioritize care as warranted from high-low
risk. Additionally, the healthcare and/or social benefits
provider can use the SVRP visualization to identify an
individual’s highest negative outcome risk to prioritize
and mitigate.
Of equal value to the DoD and VA, the capability
to represent the SVRP with a single number creates
the ability to aggregate multiple SVRPs for population
analysis for health policy and resource decisions at a
universal level.
Fig. 5. SVRP Benefits: Tailorability for healthcare/social benefits
providers and policy makers.
V. APPLICATIONS
With the SVRP fully constructed and simplified for an
individual transitioning Service member/Veteran, health-
care and/or social benefits providers now have a tool that
can be used to identify and prioritize individuals either
numerically or visually. We can also expand the use of
the SVRP for n individuals with similar or different
negative outcomes where we would expect to see n
distinct SVRPs. Therefore, observing the collection of
SVRPs:
{SVRP1, SVRP2, . . . , SVRPn} (24)
would also be of interest. For example, if we visualize
the SVRPs for two individuals n = 2 (see Figure
5), individual A has a high risk for suicide whereas
individual B has a high risk for homelessness. This
visualization allows the “healthcare and/or social benefits
provider” to target and prioritize interventions based
on the individual’s highest potential risk of negative
outcome(s).
But if we modify the visualization with the same data
to accommodate a policy maker, we notice suicide is
prevalent in both A and B, allowing the policy maker
to identity the high priority negative outcome for either
policy development/modification or proper resourcing
versus focusing on a lower priority exposure.
Note for consistency and broader use, it is crucial
that every vm,n for an SVRI be the same when creating
an SVRP. For example, if SVRI1 has been defined
for a suicide exposure or SVRI1 = SVRIsuicide, then
the v1,1 position in the matrix array will always be
the poverty status measure for SVRIsuicide, the v1,2
position will always be the unemployment status for
SVRIsuicide, and the v1,3 position will always be the
clinical evidence in the individual’s medical record for
19. SVRIsuicide. The same would apply if SVRI2 is for
a homelessness, SVRIhomelessness, SVRI3 is for 1st
episode psychosis, SVRI1st episode psychosis, and so on for
an SVRI1 to SVRIM . Appreciating the example in
Figure 5 provides value for healthcare/social benefits
providers at the individual level and policy makers at
the aggregate level, now consider collating the overall
risks (numerical solutions) for multiple SVRPs derived
from (21) for very large populations.
This can be visualized using a notional data for a
subpopulation for Veterans, for example, the VA’s health-
care regions (North East, South East, North West, South
West). Populating the avg(SVRP) for every individual in
the hypothetical VA’s regional population with notional
data, we can visualize the negative outcomes of the entire
VA population in Figure 6.
Fig. 6. Notional representation of aggregated avg(SVRP)s for a large
population (e.g. US Veteran population).
Visually, this can be overwhelming, so if we rearrange
the risk values in descending order we get a more practi-
cal visualization for SVRP population curve (Figure 7).
However, to understand the overall risk of the popu-
lation and/or to make comparisons between populations
it makes sense to create a qualitative measure for each
population curve. This can be represented by the area
under the curve of the graph in Figure 7. It turns out
that the AUC equals the average across the population.
Suppose we wish to compare two different populations
A and B. If AUC(A) AUC(B) then population B has
a higher overall risk. The AUC is computed using (21)
for each individual SVPRa in population A and SVPRb
in population B. That is,
AUC(A) =
1
|A|
X
a∈A
SVRPa = avg(SVRP(A)) (25)
and
AUC(B) =
1
|B|
X
b∈B
SVRPb = avg(SVRP(B)) (26)
Fig. 7. Rearranging aggregated avg(SVRP)s for a large population
(e.g. US Veteran population).
or generalizing
AUC(X) =
1
|X|
X
x∈X
SVRPx = avg(SVRP(X)),
(27)
where |X| is the size, or number, of individuals in the
population X.
Using (27) the AUC(X) in Figure 7 is 0.526. This
numerical representation for the overall negative out-
come risks of the US veteran population can easily
be compared to other regions or partitioned for deeper
analysis into various VA regions for comparison between
the regions.
More importantly, decision makers can further exam-
ine the raw data to:
1) identify which negative outcomes are most preva-
lent,
2) identify the individuals or groups at elevated risk,
or
3) identify groups of individuals that require more
evaluation and proper funding for high risk areas
to mention a few uses.
VI. DISCUSSION
Key for the success of the SVRP will be the mon-
itoring, collection, identification, and understanding of
different types of negative outcome and the integration
of multiple data streams into a unified framework that
can provide useful information to improve transitioning
Service member/Veteran outcomes. Additionally, several
ethical and privacy-related issues must be navigated as
SVRP is implemented. The most complex of these issues
involve identifiably, the increasingly sensitive nature of
mental health information, and the limits of confidential-
ity.
20. where the aggregate information can be used to inform
and guide decision makers to make more informed policy
and resource decisions.

But before the SVRP can be implemented, further
studies will be needed to validate and refine t he math-
ematical expression/process to develop statistically val-
idated algorithms to determine health risk profiles and
drive preventative strategies for individuals. Once vali-
dated, an implementation plan to apply individual data
to SVRP models that result in risk profiles t o inform
individuals for preventative behaviors and improved out-
comes will be established. This includes ensuring all
data is collected using validated, approved methods
and analyzed with appropriate quality and regulatory
requirement for use in the individual’s health record. In
the long-term, the SVRP will translate these findings into
clinically and non-clinically actionable recommendations
improving TSM/Veteran well-being.
VII. CONCLUSION
Bold ideas and constructs require sound foundations.
In the case of the SVRP it became imperative to develop
the mathematical expression and process to describe the
construct: the first to combine clinical and social deter-
minants into one individual risk profile. With t he math
the SVRP can now be turned into machine language and
developed into a modern tool to better understand the
effects of transiting service member from the military
into civilian life decreasing the negative outcomes as-
sociated with transition and improving TSM/Veteran’s
overall quality of life.
Though early in its development, the SVRP
displays individual and population risks through
user-friendly visualizations and quantitative values.
Ultimately this framework will be implemented
as part of a future Decision Support System
(CDSS) within the DoD/VA healthcare system’s
Electronic Health Record, where the SVRP seamlessly
ingest clinical and social determinant data at the
individual level and calculates personal risk profiles
