Self-Management in this presentation refers to those activities people undertake in an effort to promote health, prevent disease, limit illness, and restore well being. Several investigators contend that self-management be made a major component of many patient health-care strategy (Glasgow, et al., 2001; Wagner, et al., 2001). Currently, nearly 125 million Americans suffer from chronic debilitating illnesses (Anderson, 2000). These national figures clearly underscore the need to develop a multidimensional approach in regards to disease management. Accordingly, measures that incorporate the patient’s perspective in managing his or her health should be explored.
Diabetes mellitus is among those conditions suspected to be highly influenced by self-management activities (Sprangers, et. al., 2000). If benefits do indeed exist, they need to be fully evidenced. The investigation presented here sought to examine the role self management plays in the health outcomes of individuals living with diabetes.

12. Public Health Medicine’s Response to
Diabetes
Diabetes Self-Management
Definition – those activities people undertake in an effort to promote health, prevent
disease, limit illness, and restore well being
Rigorous medication compliance
Regular clinical visits
Routine HbA1C testing
Multi-daily blood-glucose self checks
Proper insulin administration
Improved dieting and exercise
Scrupulous foot care
Systematic disease monitoring
Requires
Hard work and Perseverance
Education and Training
14. Diabetes Self-Management Education
DSME was designed by a Diabetes Task Force to establish
National Standards for DM self-care
Provides the knowledge and training to perform diabetes self-
care tasks.
Primary Objective:
Manage “Glycemic Status”
Improve Diabetes Outcome
Recognized by the ADA as an essential part of diabetes care.
15. Diabetes Self-Management Education
Theoretically Framework
Health Belief Model
->Perceived susceptibility, severity, barriers, and benefits
Social Support Model
->Emotional, Instrumental, Informational, and Appraisal Support
Social Cognitive Theory - acquisition of knowledge through
observation
-> Self-Efficacy – the belief in one’s ability to execute a course of action
16. Diabetes Self-Management Education
There is no one “best” education program or approach;
however, DSME programs are guided by a set of core
principles.
Patient-Centered
Objective-Oriented
Age-Specific
Lifestyle and Behavior Based
Culturally-Sensitive
Group-Assisted
17. Diabetes Self-Management Education
Why is DSME a good strategy?
How can you effectively self-manage a complex disease
without education and training?
Each $1 spent on outpatient diabetes education saves $2 to
$3 dollars in hospitalization costs (APhA Foundation 2003
Statistics - JAPhA)
Patients who never received self-management education
were 4 times more likely to develop a chronic complication
(Nicolucci Study)
19. Diabetes Self-Management
Question:
“Will the relationship (correlation)between
Diabetes Self-Management and Diabetes
Outcomes seen in the literature be
evidenced in other patient populations?”

26. Project Goals & Objectives
Goal: To conduct a correlation study to determine the effect of
diabetes self-management on clinical outcomes for diabetic patients
served by Watts Primary Care.
The administration of DSMA Surveys with WPC patients.
The administration of a Demographic & Physiologic Surveys with WPC patients.
The assessment of diabetes clinical outcomes among WPC patients.
Study Questions:
Is there a significant correlation between diabetes self care (DSMA) and diabetes
outcome (HbA1C levels) in an adult population group currently receiving medical
care?
Are any co-variables (demographic characteristics: age, race, gender, education,
income; or physiologic characteristics: BMI, duration of diabetes, treatment-type, and
diabetic complications) related to diabetes outcome?
Hypotheses:
There will be a statistically significant correlation between self-care and DM outcome.
There will be a particular set of subject characteristics related to DM outcome.
27. Diabetes Outcomes & Self-Management:
Operational Definitions
Diabetes Outcome is defined as a clinical interpretation of
one’s glycemic status, including one’s risk for diabetic
complications (Goldstein et al., 2004).
Measured by the Hemoglobin A1C test (<6.5% is Ideal)
Diabetes Self-Management is defined as the performance of
a variety of DM self-care activities and skill sets (Toobert &
Glasgow, 2000).
Measured by the Diabetes Self-Management Activities (DSMA) survey
28. Diabetes SelfManagement Activities
(DSMA) Survey:
The DSMA is a 12-item
questionnaire frequently
used to assess the degree of
diabetes self-management
in the seven days preceding
the questionnaire.
Five Sections: dietary
habits, exercise routine,
self-monitoring of blood
glucose (SMBG), foot-care
practice, and medication
compliance.
Combined Scores: 0 to 77
Glasgow reported internal
consistency and reliability
through inter-item
reliability testing.
30. Capstone Project Study Design
Descriptive correlation (observational) study
Independent variables

34. Project Data Analysis
Data Analysis: SPSS
Mixed-Effect Model
Correlation
Two methods
The unadjusted univariate method assessed the correlation between the
independent variables (DSMA, demographic characteristics, and
physiological characteristics) and the dependent variable (HbA1C) with
random effect.
The adjusted univariate method assessed the correlation between the
independent variable (DSMA) and the dependent variable (HbA1C) with
covariates that turned statistically significant in the unadjusted univariate
method with random effect.
Random effect was assigned to choice of primary care provider.
39. Project Results:
MEM Statistics:
Question 1:
“Is there a correlation
between self care (DSMA)
and DM control (HbA1C
levels) in an adult
population group currently
receiving medical care?”
Findings:
There was no statistically
significant correlation
between any of the DSMA
subscales and HbA1C
(p<0.05).
40. Project Results:
MEM Statistics:
Question 2:
“Are any co-variables
(demographic characteristics:
age, gender, marital status,
education, employment,
income, and health coverage;
or physiologic characteristics:
DM history, DM family history,
DM medication, DM therapy
type, DM education, DM
complications, smoking
history, and BMI) related to
DM control (HbA1C levels)?”
Findings:
Of the tested co-variables, age,
gender, DM complications, DM
history, DM therapy type, and
BMI demonstrated a
statistically significant
relationship with HbA1C levels
(p<0.05).
41. Project Results
DSMA subscales did not demonstrate any statistically
significant correlation with HbA1C scores.
Does not support the hypothesis that diabetic patients who practice DM
self-care activities present with improved glycemic numbers compared
to patients who do not practice such measures.
The co-variables, age, gender, DM therapy type, DM
history, DM complications, and BMI did demonstrated a
statistically significant relationship with HbA1C levels .
Supports the hypothesis that certain demographic/physiologic
characteristics do indeed influence diabetes outcome.
Significance:
Reduction in HbA1C values by just 1% has proven to reduce diabetic
complications by as much as 25% (UKPDS, 1998).
42. Project Discussion
Although not evidenced here, diabetes self-care activities based
on DSME standards still might play an important role in
glycemic control and reducing DM complications.
One of the many diabetes-related aims of Healthy People 2020
(HP 2020) is to increase the proportion of individuals receiving
formal diabetes health education (USDHHS, 2012).
The current national average is 56.8% of diabetic patients receive
diabetes health education and the HP 2020 target is 62.5 % by
the year 2020 (USDHHS, 2012).
43. Project Limitations
Limitations
Observational (versus Experimental Study)
Pros – Observational Studies seem to be less affected by Threats to Internal Validity
Maturation
Repeated Testing
Instrumentality
Regression Towards Means
Attrition
Diffusion
Cons
Not Randomized - Volunteers
No Control Group
No Baseline
Self-Reported Surveys (Instrumentation)
Self-efficacy – not measured
Social Support – not measured
44. Recommendations
Despite this study’s findings, providing patients access to
DSME services at WPC has the real potential of improving
health outcomes.
Similar clinical models that incorporate DSME could serve
as a national model.
WPC should continue offering DSME as part of their
current health care services.
45. Lessons Learned
The impact of Social Determinants of Health can never
be overlooked: In this study Economic, Social, Service,
and Physical Environment could have played a major
underlining role; factors such as Self-Efficacy, Life
Course, and Food Deserts need to be considered.
To that point, although a movement towards a
National Diabetes Education agenda seems promising,
in order to reach HP2020 goals additional studies that
investigate the role Social Determinants play in DSME
and DM outcomes need to be pursued.

Change to objectives
Patients who were 49 years of age or younger had HbA1C scores 1.13 % higher than those who were 50 years or older (beta= 1.13, SE=0.22, p= 0.026). Male patients presented HbA1C levels 0.94% higher than female patients (beta= 0.94, SE= 0.19, p= 0.041). Patients who indicated no diabetes complications possessed HbA1C scores 2.03% less than those who reported at least one DM complication (beta= -2.3, SE= 0.41, p= 0.037). Patients with a history of DM less than 10 years had HbA1C values 0.01% higher than those with a history greater than 10 years (beta= 0.01, SE= 0.25, P= 0.049). Patients on insulin therapy had HbA1C values 1.53% higher than those who were not (beta= 1.53, SE= 0.63, P= 0.0037). BMI proved to be statistically significant as well. Results demonstrated that with every point increase in BMI, HbA1C values increased by 2.06% (beta=2.06, SE= 0.37, p= 0.009). Table 6 summarizes the “Co-variables x HbA1C” correlation results of the study participants.
