Did Medicaid Expansion Under The Affordable Care Act Reduce The Likelihood That People Report Employment Status Changes Due To Health, U.S., 2009-2017, Songyuan Deng

Theses and Dissertations

Medicaid expansion of Affordable Care Act (ACA) extended coverage to low-income working adults. While Medicaid expansion led to increased healthcare use and national healthcare expenditures, current studies do not examine the effects of Medicaid expansion on health status from the perspective of social roles, for example, changes in employment status. This study use data from the Current Population Survey to examine the association between Medicaid expansion and the probability to attribute part-time work or not-in-labor- force to health issues among people with family annual income no more than 138 of Federal Poverty Level, with a difference-in-differences study design. We found …

Examining Women’S Perceptions Of Maternity Care In Public And Private Sectors Of National Guard Hospitals In Saudi Arabia: A Qualitative Study, Hanin M. Almahmoud

Theses and Dissertations

Every second, a baby is born. The process of birth is a complex one – biologically, medically, and emotionally. In particular, women in labor need both physical and emotional care. They need to be heard, to be comforted, and to be safe.

Women’s satisfaction can be used as a legitimate way to measure the quality of maternity care. Moreover, when health systems practice patient-centered care and listen to women’s concerns and what they want out of their care, it can lead to improvements in their satisfaction. Hospitals in Saudi Arabia are considered to be among the best and most technologically …

The Intergenerational Effects Of Adverse Childhood Experiences On Children’S Emergency Department Utilization And Depression And Anxiety In South Carolina, Eboni E. Haynes

Theses and Dissertations

Adult exposure to adverse childhood experiences (ACEs) is common in the U.S., with over half of adults reporting exposure to at least one ACE. Childhood trauma is associated with risk factors for premature death, disability, poor physical and mental health, and lower quality of life in adults. Traumatic experiences also influence parenting behaviors later in life, placing offspring at an increased risk of ACE exposure. Few studies have explored the intergenerational effects of ACEs on the health and well-being of offspring. This study sought to identify whether associations existed between caregiver ACE exposures and emergency department (ED) utilization for sick …

Clinically Integrated Networks: The ‘Magic Pill’ For Improving The Quality Of Health Care?, Kaitlyn Ann Crosby

Theses and Dissertations

The Patient Protection and Affordable Care Act (ACA) served as a paradigm shift to reimburse physicians based on health outcomes or quality of care patients receive in relation to and conscious of the cost to provide care, rather than the traditional fee-for- service (FFS) system. To implement value-based care under the ACA, value-based care models (VBCM), such as patient-centered medical homes (PCMH) and accountable care organizations (ACO), were formed with the ultimate goal to advance quality of care. Among commercially insured populations, clinically integrated networks (CIN) have emerged as another type of VBCM.

Since CINs are the newest type of …

Dietary Advanced Glycation End-Products (Ages) And Breast Cancer Risk And Survival, Omonefe Opeyemi Omofuma

Theses and Dissertations

Introduction: Advanced glycation end-products (AGEs) are implicated in the pathogenesis of chronic diseases including cancer. AGEs are produced endogenously and are also consumed from foods. High amounts of AGEs are found in animal products and processed foods, and AGE formation is accelerated during cooking at high temperatures. Using data from the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial (PLCO), we assigned and quantified NƐ-carboxymethyl-lysine (CML)-AGE content in food and investigated the association between dietary AGE intake and breast cancer (BrCa) risk. We assessed whether the risk was modified by race/ethnicity, obesity status, fruit and vegetable intake, BrCa invasiveness …

The Association Of Health Insurance And Prescription Drug Coverage On Cost-Related Non-Adherence And Hospitalization Across Age-Related Groups Of Individuals With Copd, Shamika Martin Walls

Theses and Dissertations

Background: COPD patients have poor adherence to prescribed treatment. Individuals with COPD have higher out-of-pocket treatment cost than individuals without COPD. The significant out of pocket COPD related treatment cost can lead to prescription drug non-adherence especially for individuals without health insurance or prescription drug coverage.

Significance: Since the implementation of Medicare Part D on January 1, 2006, there are no studies that have used national data to evaluate the association of health insurance and prescription drug coverage on cost related non-adherence and hospitalization among individuals 50-64 years old with COPD compared to individuals 65 years and older …

The Relationship Between The Electronic Health Record Patient Portal And Shared Decision Making, Gloria Esoimeme

Theses and Dissertations

Shared decision making (SDM) is a collaborative decision-making style where the patient and the physician are involved in the clinical decision-making process. The goal of this dissertation project was to examine the relationship between the patient portal of an electronic health record (EHR) and SDM.

The SDM process has three main components: information sharing, deliberation and decision making. Patients participate in SDM at varying levels: some patients may prefer to share information and deliberate but leave the final decision making to the provider while others prefer to participate in all the three components of SDM. The patient portal of an …

Hiv Care Location: An Evaluation Of Single Versus Multi Facility Utilization Of Hiv/Aids Care Services And Patient Health Outcomes And Clinical Indicators In South Carolina, Melanie Gwynn

Theses and Dissertations

Background: On the HIV/AIDS care continuum, the “retention in care” metric does not distinguish between single-facility (SF) or multi-clinic utilization (MC), also described as HIV care location (or type). SF utilization is vital as it has been linked optimal clinical outcomes among People Living with HIV/AIDS (PLWH). Published research detailing the prevalence of HIV care type and its association with health outcomes/clinical indicators, has been studied only in limited urban settings. Additionally, coinfections such as sexually transmitted infections (STIs), have yet to be evaluated as potential predictive factors for HIV care type.

Methods: A cross-sectional design was used …

Health Insurance Program For The Poor, Out-Of-Pocket Costs, And Catastrophic Health Expenditures In India, Shyamkumar Sriram

Theses and Dissertations

Background

India is currently taking steps to provide Universal Health Coverage (UHC) as envisaged in its National Health Policy 2017. Financial protection is considered the backbone of UHC. In India, OOP expenses accounts for about 62.6% of total health expenditure - one of the highest in the world. Out of 1.324 billion people in India, around 12.4% of the population is below the poverty line. Lack of health insurance coverage and inadequate coverage are important reasons for high OOP health expenditures. High OOP health expenditures push many households into poverty. The objective of this research is to examine the effect …

Longitudinal Trajectories Of Depressive Symptoms Among Youth And Young Adults With Type 1 Diabetes: Predictors And Health Outcomes, Melanie Whitmire Sutherland

Theses and Dissertations

Type 1 diabetes (T1D) is one of the most frequently diagnosed chronic illnesses among youth, and has many long-term complications, including retinopathy, neuropathy, and cardiovascular disease. The risk of these complications may be reduced through maintaining glycemic control and one potential risk factor for failure to achieve optimal glycemic control is elevated depressive symptoms among youth and young adults (YYA) with T1D. YYA with T1D are at increased risk of depression, which has been associated with adverse outcomes such as poor adherence to self-management and poor glycemic control. Although a robust body of research exists on the association between comorbid …

An Evidence Based Rationale For Making Tick - Borne Relapsing Fever A Nationally Notifiable Disease, Kyle M. Hatcher

Theses and Dissertations

Tick – borne relapsing fever (TBRF) is globally dispersed, and within the United States is found primarily in the mid – west, south - west, and north – west portions of the country. TBRF is a disease which causes patients to experience flu – like symptoms and is distinguished by multiple relapses of high fever which can cause individuals to be hospitalized multiple times over months. TBRF is caused by Borrelia spp. spirochetes and spread by Onthidoros spp. soft – shelled ticks. First diagnosed in the early 20th century, the disease has gone underdiagnosed and has attracted little attention for …

The Association Of Cardiorespiratory Fitness With Advancing Age Among Those With And Without Type Ii Diabetes, Amber Kathlyn Watson

OBJECTIVE: This study examined the relationship between cardiorespiratory fitness (CRF) and age to determine if the decrease in CRF associated with advancing age is greater among those with type 2 diabetes mellitus (T2DM) as compared to those without T2DM. This study also assessed if differences in CRF between persons with T2DM and those without are consistent across CRF percentiles.

METHODS: Data from the Aerobics Center Longitudinal Study (ACLS, Dallas, Texas, 1970-2006) were utilized in the current study. CRF was measured by maximal treadmill exercise testing using the Balke protocol and T2DM status was determined by self-report of previous diagnosis by …

The Association Of Rural Hospital Closures With In-Hospital And 30-Day Post Hospital Discharge Mortality From Emergency Care Sensitive Conditions, Melinda A. Merrell

Theses and Dissertations

Purpose

Over 100 rural hospitals have closed in the U.S. since 2010. Continuous pressures on the rural health care delivery system suggest that the trajectory of closures will continue in at least the short-term. While the causes of rural hospital closures have been described in the literature, the effects on the health outcomes of populations that experience these closures are still poorly understood. The purpose of this study was to determine associations between rural hospital closures and in-hospital and 30-day post hospital discharge mortality rates for affected residents experiencing time-sensitive emergencies in two U.S. states.

Methods

Rural hospital closures were …

Experience Of Persistent Pain Among Military Service Members Participating In An Interdisciplinary Intensive Outpatient Program, Barbara Katarzyna Bujak

Theses and Dissertations

Persistent pain is one of today’s most complex issues in healthcare. In the U.S. military, persistent pain affects close to half of the service members who have deployed overseas and up to 73.2% of service members and veterans experiencing persistent pain. Interdisciplinary pain management, considered one of the most effective ways to manage persistent pain, utilizes the biopsychosocial model that illustrates the dynamic interaction between the physiological, psychological and social factors involved in the experience of persistent pain. Effective interdisciplinary programs address all components of the model and result in better coping skills to self-manage persistent pain, decreased fear of …

Behavioral And Neural Correlates Of Aging Effects On Temporal Predictive Mechanisms During Speech Production And Limb Movement, Karim Joharikhatoonabad

Theses and Dissertations

Existing evidence suggests that the brain facilitates motor responses to temporally predictable sensory inputs by generating more robust predictions about the timing of incoming stimuli to better estimate the next state of movement. In this context, previous studies have shown that motor responses are generated with faster reaction time in response to sensory stimuli with predictable compared to those with unpredictable temporal dynamics. However, our understanding of the underlying behavioral and neural mechanisms of temporal predictive mechanisms during movement production has remained limited by several factors. First, studies regarding temporal predictive mechanisms have mainly examined limb movement as a target …

Association Between Snps In The Vitamin D Binding Protein, Vitamin D Status, And Aggressive Prostate Cancer By Race, Diana Diaz

Theses and Dissertations

Prostate cancer incidence and mortality have been decreasing in recent years, but it remains the most commonly diagnosed cancer among men. Racial disparities exist in prostate cancer with African Americans (AAs) having notably higher rates of incidence and mortality, lower survival rates, and are more likely to be diagnosed with a highergrade cancer compared to European Americans (EAs). Genome-wide association studies have revealed several single nucleotide polymorphisms (SNPs) within the vitamin Drelated GC gene that may be associated with prostate cancer aggressiveness. In addition to SNPs, previous research has suggested that low levels of 25-hydroxyvitamin D (25(OH)D) may be related …

Pre-Exposure Prophylaxis (Prep) For Hiv Prevention: A Mixed-Methods Study Of Sexual Risks And Knowledge, Perceptions, And Willingness Of Prep Use Among African American Women In The South, Jamie Troutman

Theses and Dissertations

There are approximately 1.1 million people living with HIV in United States, with nearly 40,000 new diagnoses annually. Significant regional and racial disparities are associated with HIV diagnoses — with the South experiencing the greatest burden of HIV and African American women accounting for 60% of new diagnoses among women. Pre-exposure prophylaxis (PrEP) has been designated as an effective tool to prevent HIV transmission among individuals who may be at risk of HIV infection. Earlier PrEP research has focused mainly on at-risk groups such as men who have sex with men (MSM). Previous PrEP research involving African American women included …

Role Of Heart Rate Variability Biofeedback In Cognitive Performance, Chronic Pain, And Related Symptoms, James P. Winstead

Theses and Dissertations

Over-modulation of the sympathetic nervous system and reduced heart rate variability (HRV) are commonly overlooked components of pain, poor cognition (decreased attention, recall, and cognitive processing), depression, stress, and fatigue. HRV Biofeedback (HRVB) training induces HRV coherence to balance the autonomic system. Paced breathing (~6 breaths/minute) increases HRV coherence. This randomized, controlled intervention trial tested the hypothesis that HRVB would improve HRV coherence, pain (severity, interference, and catastrophizing), cognitive performance, and reduce depressive, stress, and fatigue symptoms and pain medication use in veterans. Participants were randomized to previously established HRVB or control protocols. Each participant completed a Baseline Assessment, 6 …

Disparities In Non-Small Cell Lung Cancer In The United States: An Examination Of Treatment, Survival, And Access To Care, Cassie Lewis Odahowski

Theses and Dissertations

Lung cancer is the leading cause of cancer-related deaths in the United States with a 5-year survival rate of only 18%. Differences in access to care and treatment utilization may play a role in observed survival disparities among rural patient populations. This dissertation aimed to examine rural disparities in all-cause and lung-cancer specific survival, time to treatment initiation, and utilization of surgical treatment among non-small cell lung cancer cases.

We utilized comprehensive cancer registry data from the Surveillance, Epidemiology, and End Results program linked with Medicare billing claims (SEER-Medicare) for non-small cell lung cancer (NSCLC) patients diagnosed between 2003-2011. We …

Disparities In Colorectal Cancer: Measuring Spatial Accessibility, Screening, And Surveillance Outcomes In South Carolina, Michele J. Josey

Theses and Dissertations

The purpose of this dissertation project is to add to the growing literature about the multi-faceted aspects of colorectal cancer (CRC) prevention and related disparities. We focused on the spatial distribution of facilities performing screening services to identify areas that underutilize colonoscopy screening. Next, we examined how the food and physical activity environment affects precursors of CRC by considering plausible pathways. Finally, we explored if access to health insurance reduced the racial disparity of receiving a timely surveillance colonoscopy after a CRC diagnosis.

We utilized the SC Ambulatory Surgery Discharge Database, an all-payer, population-based outpatient dataset with colonoscopy records from …

Effect Of Heart Rate Variability Biofeedback On Sleep, Joshua Mercadel

Theses and Dissertations

Healthy amounts of sleep is vital for normal human functions such as daily learning, memory, emotional state and cardiovascular function. Studies conducted previously have shown sleep deprivation to be associated with increases in sympathetic activity contributing to autonomic nervous system (ANS) dysregulation. HRV biofeedback (HRVB) training induces HRV coherence, a condition that maximizes HRV and facilitates autonomic and cardiorespiratory homeostasis. This randomized, controlled, intervention trial will test the hypothesis that HRVB can improve HRV coherence and increase overall sleep quality. Patients are randomized to previously established HRVB or sham protocols (n=40 each, total planned enrollment N=80). Each participant completes a …

The Plant-Based And Soul-Full Study (Pass): Examining How Owners Of Local Vegan Soul Food Restaurants Promote The Consumption Of Vegan Foods In The African American Community, Anthony Crimarco

Theses and Dissertations

Background: Obesity remains a prevalent public health epidemic and African American (AA) adults are disproportionately affected by obesity more than any other ethnic group. There are also disparities in obesity by location, with the South having the highest rates compared to other geographic regions in the United States. Addressing poor dietary habits is important for improving obesity rates among AAs, but there has been limited research that has focused on specifically developing culturally-tailored interventions. With a recent number of soul food restaurants serving exclusively vegan meals opening up across the country to appeal to AAs and others interested in eating …

Exploring Breast Cancer Care Variation In Coc-Accredited Facilities, Sarah Grace Barron

Theses and Dissertations

INTRODUCTION: While improvements have been made in reducing breast cancer incidence and mortality over the past twenty years, disparities in breast cancer mortality remain. Understanding systematic differences in breast cancer treatment and quality of care remain at the epicenter of understanding breast cancer disparities. Needle biopsy is a less invasive and less expensive diagnostic test for breast cancer (as compared to excisional biopsy) and permits diagnosis while avoiding unnecessary surgery. This study was conducted to 1) examine how the National Quality Forum (NQF)-endorsed needle biopsy utilization measure varies geographically (i.e. state and region) and 2) determine the patient- and/or health …

Social Networks, Social Support, And Contextual Factors That Affect Blood Glucose Control Among Individuals With Type 2 Diabetes Mellitus In Urban Ghana, Marian O. Botchway

Theses and Dissertations

This study used primary data from Kumasi, Ghana, to examine whether social networks, social support, diabetes-related stigma, religion, and traditional medicine affected blood glucose (HbA1c) control among adults with type 2 diabetes mellitus (T2DM). First, the study evaluated whether three social network characteristics (kin composition, household composition, and network density) were directly or indirectly (via social support) associated with HbA1c. Kin composition and household composition were significantly associated with social support. Neither network characteristics nor social support were associated with HbA1c, which suggests that social network characteristics may operate through mechanisms other than social support to affect HbA1c among study …

Prevalence Trends Of Victimization Among High School Students By Race, Ethnicity, And Gender – Yrbss 2009-2017, Carlos Avalos

Theses and Dissertations

Introduction: Students who are victimized at school are more likely to report mental health, behavioral, and academic problems. Bullying and electronic bullying are types of victimization that are prevalent in US schools, with prevalence varying by race and ethnicity, gender, and age. Additionally, due to increases in bias-based harassment (such as being targeted due to race, ethnicity, or religious beliefs) in the country over the last few years, it is of interest to see how victimization behaviors in schools may have changed from 2015 to 2017.

Objective: To analyze trends of overall bullying, school bullying, electronic bullying, and other forms …

Sociocultural Factors Influencing Cervical Cancer Prevention And Control Behaviors In Cusco, Peru, Venice Elizabeth Haynes

Theses and Dissertations

Cervical cancer is one of the most preventable types of cancer; however, it continues to pose significant health challenges for women in low and middle-income countries (LMICs), particularly in Peru. Studies previously conducted in Peru have examined factors associated with cervical cancer screening, screening access, availability, and geographical determinants on cervical cancer incidence and mortality. These studies have suggested the need to explore sociocultural factors and the roles of men and women in screening decisions associated with excessive cervical cancer burden and low rates of screening among Peruvian women. The goal of the dissertation research was to explore influences of …

Evaluating Impacts Of A Multilevel Resilience-Based Psychosocial Intervention On Mental Health Of Children Affected By Parental Hiv In China, Yanping Jiang

Theses and Dissertations

Background: Children affected by parental HIV are commonly exposed to multiple risk factors, including parental illness and death, other traumatic life events, HIV stigma, and poverty, all of which in turn put them at elevated risk of experiencing poor mental health outcomes. Previous research has suggested the promise of psychosocial interventions in improving mental health for children affected by parental HIV through an integrated and multilevel resilience-based approach. However, there are few multilevel resilience-based interventions for this group, and the efficacy of such interventions on mental health outcomes has not been fully examined. Furthermore, very few studies have examined whether …
