Two Essays On Leveraging Analytics To Improve Healthcare, Deepika Gopukumar

Theses and Dissertations

The healthcare cost has continued to increase over the past few years despite various policies, efforts, and initiatives taken by the government. It is still projected to grow over the next few years by the Centers for Medicare and Medicaid Services (CMS). Readmissions have been a major contributor to the increase in costs and have always been a contributing factor. To get a perspective, considering the fact that at least 9% of individuals who had COVID-19 were likely to get readmitted shortly, according to a study by the Centers for Disease Control and Prevention (CDC) COVID-19 response team, along with …

The Assessment Of Technology Adoption Interventions And Outcome Achievement Related To The Use Of A Clinical Research Data Warehouse, Katie A. Mccarthy

Theses and Dissertations

Introduction: While funding for research has declined since 2004, the need for rapid, innovative, and lifesaving clinical and translational research has never been greater due to the rise in chronic health conditions, which have resulted in lower life expectancy and higher rates of mortality and adverse outcomes. Finding effective diagnostic and treatment methods to address the complex challenges in individual and population health will require a team science approach, creating the need for multidisciplinary collaboration among practitioners and researchers.

To address this need, the National Institutes of Health (NIH) created the Clinical and Translational Science Awards (CTSA) program. The CTSA …

Quantitative Phenotype Analysis To Identify, Validate And Compare Rat Disease Models, Yiqing Zhao

Theses and Dissertations

Introduction

The laboratory rat has been widely used as an animal model in biomedical research. There are many strains exhibiting a wide variety of phenotypes. Capturing these phenotypes in a centralized database provides researchers with an easy method for choosing the appropriate strains for their studies. Current resources such as NBRP and PhysGen provided some preliminary work in rat phenotype databases. However, there are drawbacks in both projects: (1) small number of animals (6 rats) used by NBRP; (2) NBRP project is a one-time effort for each strain; (3) PhysGen web interface only enables queries within a single study – …

Utilizing Consumer Health Posts For Pharmacovigilance: Identifying Underlying Factors Associated With Patients’ Attitudes Towards Antidepressants, Maryam Zolnoori

Theses and Dissertations

Non-adherence to antidepressants is a major obstacle to antidepressants therapeutic benefits, resulting in increased risk of relapse, emergency visits, and significant burden on individuals and the healthcare system. Several studies showed that non-adherence is weakly associated with personal and clinical variables, but strongly associated with patients’ beliefs and attitudes towards medications. The traditional methods for identifying the key dimensions of patients’ attitudes towards antidepressants are associated with some methodological limitations, such as concern about confidentiality of personal information. In this study, attempts have been made to address the limitations by utilizing patients’ self report experiences in online healthcare forums to …

The Utility Of Mobile Phones For Health Among Women Living With Hiv In Urban Malawi, Linda Marie Dietrich

Theses and Dissertations

The use of mobile phones are becoming ubiquitous with growing interest by healthcare providers to utilize mobile phone technology for various health-related applications, called mHealth. This is especially true in low-income countries such as those in sub-Saharan Africa. When implementing mHealth applications, it is important to understand the dynamic social, cultural and environmental factors where mHealth will be implemented to ensure that interventions developed are effective. A qualitative study to explore the sociotechnical factors experienced by women participating in an HIV support group in urban Malawi was conducted to enhance our understanding of women’s experience with mobile phone use and …

Health In Your Hand: Assessment Of Clinicians’ Readiness To Adopt Mhealth Into Rural Patient Care, Bryan Weichelt

Theses and Dissertations

Introduction: Technology is as much rural as it is urban, but mobile health (mHealth) could have a unique impact on health and quality of life for rural populations. The adoption of mobile technologies has soared in recent decades leading to new possibilities for mHealth use. This project considers the impact of these technologies on rural populations. Specifically, it is focused on assessing the barriers of physicians and healthcare organizations to adopt mHealth into their care plans. Gaps in knowledge exist in assessing organizational readiness for mHealth adoption, the use of patient-reported data, and the impact on rural healthcare. This project …

Exploring Interactive Survivorship Plans: Patient Perceived Value, Acceptance And Usability Evaluation Of An Online Breast Cancer Survivorship Tool, Akshat Kapoor

Theses and Dissertations

Introduction: Having recently been discharged from the hospital, several breast cancer survivors find themselves unable to adjust to the transition and take charge of their own health, away from the confines of the hospital.

With the rapid advancement in treatment methods and techniques, the rate of breast cancer survivors has grown exponentially. It is crucial to provide adequate means to support cancer survivors in an active manner. This includes regular monitoring for recurrence (or occurrence of new cancers), handling any related and non-related comorbidities, provide recommendations for preventive care as well as dealing with any long term side effects from …

Dental Hygienists' Cognitive Process In Periodontal Soft Tissue Charting, Kelsey M. Schwei

Theses and Dissertations

Introduction: Dental hygienists have not had the opportunity to be involved in the design and development of the periodontal soft tissue charts and the surrounding interface features that are used while examining dental patients in daily practice. In some cases, dentists are able to give their opinions, wants, and needs into the development of the health information systems that they use on a daily basis, but too often, the dental hygienist is forgotten about and no input is ever given to the developers from the dental hygienists. This project considers the impact of well-designed interfaces on effectiveness and workflow particularly …

Three Essays On Enhancing Clinical Trial Subject Recruitment Using Natural Language Processing And Text Mining, Euisung Jung

Theses and Dissertations

Patient recruitment and enrollment are critical factors for a successful clinical trial; however, recruitment tends to be the most common problem in most clinical trials. The success of a clinical trial depends on efficiently recruiting suitable patients to conduct the trial. Every clinical trial research has a protocol, which describes what will be done in the study and how it will be conducted. Also, the protocol ensures the safety of the trial subjects and the integrity of the data collected. The eligibility criteria section of clinical trial protocols is important because it specifies the necessary conditions that participants have to …

Using Omaha System Documentation To Understand Physical Activity Among Rural Women, Jeanette Melissa Olsen

Theses and Dissertations

Rural women are more inactive and have different barriers to physical activity than those who live in more urban settings, yet few studies have specifically examined physical activity and associated factors in this population. Clinical data documented with standardized terminology by nurses caring for rural women may provide an opportunity to generate evidence that informs and improves nursing care. However, the knowledge to be gained and utility of nurses' clinical documentation in regard to physical activity have not been explored. Accordingly, the purpose of this study was to increase understanding of physical activity and associated factors among rural women by …

Health Care Informatics Support Of A Simulated Study, Zeinab Salari Far

Theses and Dissertations

The objective of this project is to assess the value of REDCap (Harris, 2009) by conducting a simulated breast cancer clinical trial and demonstration. REDCap is a free, secure, web-based application designed to support data capture for research studies. To assess REDCap's value, we conducted a simulation of a clinical trial study designed to compare the use of two new technologies for breast cancer diagnosis and treatment with current best practice breast cancer diagnosis and treatment. We call the trial, "Real-Time Operating Room BC Diagnostic Treatment (RORBCDT)". The RORBCDT clinical trial is designed to assess the value of a new …
