Correctional Telemedicine And Its Benefits For Female Inmates, Chelsea Oliver

Applied Research Projects

The purpose of this study is to identify health issues that are specific to the female population of correctional institutions and how telemedicine would be beneficial in providing healthcare to same. A questionnaire was developed using information from literature on the topics obtained from a variety of places. Once the questionnaire was completed, a randomly selected group of telemedicine providers received the questionnaire, along with an introduction and information on the study that was being conducted.

The barriers of this study came from telemedicine providers either not responding to the questionnaire entirely or the providers only being able to answer …

Closing The Meaningful Use Gap Between Small And Large Practices, Crystal L. Jones

Applied Research Projects

The Lack of Meaningful Use Awareness in small practices is very prevalent. One may ask why there is such a gap in MU Awareness amongst small and large practices. The answer is quite the same across the board for small practices, “Cost”. This misfortune has resulted in many small practice physicians and staff being objective to the adoption of an electronic health record system. They are indifferent about the penalties that will be enforced soon, if they do not follow suite with the guidelines mandated by the ARRA. Essentially, this thesis will provide statistical data on the adoption rate of …

Increasing Patient Engagement In The African American Community Through Personal Health Record Use, Andrea Perkins

Applied Research Projects

Personal Health records have many potential benefits to patients, caregivers and institutions. In order to meet meaningful use standards EHR systems must allow patients to be able to access and easily download their healthcare records and images for their own use. Previous studies have shown that African Americans are less likely to enroll in a personal health record than other ethnic populations. This study was done to research and identify possible barriers the have limited the utilization of personal health record use in the African American community. A preliminary survey and focus group were convened to discuss issues affecting PHR …

A Structure-Preserving Hybrid-Chordal Filter For Sampling In Correlation Networksa Structure-Preserving Hybrid-Chordal Filter For Sampling In Correlation Networks, Kathryn Dempsey Cooper, Tzu-Yi Chen, Sriram Srinivasan, Sanjukta Bhowmick, Hesham Ali

Interdisciplinary Informatics Faculty Proceedings & Presentations

Biological networks are fast becoming a popular tool for modeling high-throughput data, especially due to the ability of the network model to readily identify structures with biological function. However, many networks are fraught with noise or coincidental edges, resulting in signal corruption. Previous work has found that the implementation of network filters can reduce network noise and size while revealing significant network structures, even enhancing the ability to identify these structures by exaggerating their inherent qualities. In this study, we implement a hybrid network filter that combines features from a spanning tree and near-chordal subgraph identification to show how a …

The IT Group had three goals: (1) to enhance research by obtaining the best data possible, (2) to operate successfully in the local environment and be welcomed by the local populations, and (3) to increase the efficiency and cost-effectiveness of the survey process. This paper outlines approaches to consider when designing and implementing self-administered information and communications technology (ICT) questionnaires in developing countries, and …

A Single-Parameter Model Of The Immune Response To Bacterial Invasion, Lester Caudill

Department of Math & Statistics Faculty Publications

The human immune response to bacterial pathogens is a remarkably complex process, involving many different cell types, chemical signals, and extensive lines of communication. Mathematical models of this system have become increasingly high-dimensional and complicated, as researchers seek to capture many of the major dynamics. In this paper, we argue that, in some important instances, preference should be given to low-dimensional models of immune response, as opposed to their high-dimensional counterparts. One such model is analyzed and shown to reflect many of the key phenomenological properties of the immune response in humans. Notably, this model includes a single parameter values, …

Analysing A New Mobile Bilateral Audiology Test For Children, Luke J. Brook

Theses : Honours

Hearing loss in Australian children, primarily Aboriginal and Torres Strait Islanders, is a growing concern for the Australian public health sector. In certain rural communities up to 90 per cent of children have been found to experience some form of hearing loss. Although hearing loss can be the result of a number of different causes, including congenital influences, the most common cause of hearing loss in Australian children is attributed to a common middle ear infection, otitis media.

To address the issue, numerous solutions have been proposed, tested and implemented, although the problem persists due to geographic, environmental and cultural …

Data Mining Of Pancreatic Cancer Protein Databases, Peter Revesz, Christopher Assi

School of Computing: Conference and Workshop Papers

Data mining of protein databases poses special challenges because many protein databases are non- relational whereas most data mining and machine learning algorithms assume the input data to be a type of rela- tional database that is also representable as an ARFF file. We developed a method to restructure protein databases so that they become amenable for various data mining and machine learning tools. Our restructuring method en- abled us to apply both decision tree and support vector machine classifiers to a pancreatic protein database. The SVM classifier that used both GO term and PFAM families to characterize proteins gave …

An Automated Pathological Class Level Annotation System For Volumetric Brain Images, Thien Anh Dinh, Tomi Silander, C. C. Tchoyoson Lim, Tze-Yun Leong

Research Collection School Of Computing and Information Systems

We introduce an automated, pathological class level annotation system for medical volumetric brain images. While much of the earlier work has mainly focused on annotating regions of interest in medical images, our system does not require annotated region level training data nor assumes perfect segmentation results for the regions of interest; the time and effort needed for acquiring training data are hence significantly reduced. This capability of handling high-dimensional noisy data, however, poses additional technical challenges, since statistical estimation of models for such data is prone to over-fitting. We propose a framework that combines a regularized logistic regression method and …

The Use Of Mobile Phone Cameras In Guiding Treatment Decisions For Laceration Care, Neal Sikka, Michael Pirri, Katrina Norbury Carlin, Ryan Strauss, Faisal Rahimi, Jesse M. Pines

Emergency Medicine Faculty Publications

Objectives: Mobile phone technology may be useful in helping to guide medical decisions for lacerations. We examined whether emergency department (ED) provider opinions on which lacerations require repair differed using mobile phone–generated images compared with in-person evaluations.

Subjects and Methods: Patients presenting to an urban ED for initial and follow-up laceration care were prospectively enrolled. Patients took four mobile phone pictures of their laceration and provided a medical history. Cases were reviewed by ED providers who assessed image quality and made a recommendation about whether the laceration needed repair. The same provider then assessed the patient in-person. Concordant decision-making between …

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Mobile health (mHealth) technologies hold incredible promise to improve healthcare delivery in resourcelimited settings. Network reliability across large catchment areas can be a major challenge. We performed an analysis of network failure frequency as part of a study of real-time adherence monitoring in rural Uganda. We hypothesized that the addition of short messaging service (SMS+GPRS) to the standard cellular network modality (GPRS) would reduce network disruptions and improve transmission of data.

Methods: Participants were enrolled in a study of real-time adherence monitoring in southwest Uganda. In June 2011, we began using Wisepill devices that transmit data each time the …

Meaningful Use And Meaningful Curricula: A Survey Of Health Informatics Programs In The U.S., Kai Koong, Madison Ngafeeson, Lai Lui

Journal Articles

The introduction of the US government’s Meaningful Use criteria carries with it many implications including the training curriculum of healthcare personnel. This study examines 108 health informatics degree programmes across the USA. First, the courses offered are identified and classified into generic classes. Next, these generic groupings are mapped to two important frameworks: the Learning to Manage Health Information (LMHI) academic framework; and the Meaningful Use criteria policy framework. Results suggest that while current curricula seemed acceptable in addressing Meaningful Use Stage 1 objective, there was insufficient evidence that these curricula could support Meaningful Use Stage 2 and …

Machine Learning Approach To Extract Diagnostic And Prognostic Thresholds: Application In Prognosis Of Cardiovascular Mortality, Luis J. Mena, Eber E. Orozco, Vanessa G. Felix, Rodolfo Ostos, Jesus D. Melgarejo, Gladys E. Maestre

School of Medicine Publications

Machine learning has become a powerful tool for analysing medical domains, assessing the importance of clinical parameters, and extracting medical knowledge for outcomes research. In this paper, we present a machine learning method for extracting diagnostic and prognostic thresholds, based on a symbolic classification algorithm called REMED. We evaluated the performance of our method by determining new prognostic thresholds for well-known and potential cardiovascular risk factors that are used to support medical decisions in the prognosis of fatal cardiovascular diseases. Our approach predicted 36% of cardiovascular deaths with 80% specificity and 75% general accuracy. The new method provides an innovative …

Clustered Subsampling For Clinically Informed Diagnostic Brain Mapping, Malin Björnsdotter, Diego Sona, Sonny Rosenthal, Justin Dauwels

Research Collection College of Integrative Studies

Brain based diagnostic systems have recently received attention as a tool in the characterization and diagnosis of a variety of neurodevelopmental and psychiatric disorders. Nonetheless, a majority of disorders are still diagnosed entirely based on symptom assessments and behavioral correlates. We therefore propose a method for fusing brain responses with clinical measures for improved diagnosis. To this end, we utilized the flexibility of clustered random subspace brain mapping to detect regions where brain responses in conjunction with a clinical measure could reliably differentiate patients from control subjects. We demonstrate the approach on realistically simulated functional magnetic resonance imaging (fMRI) brain …

High Acceptability For Cell Phone Text Messages To Improve Communication Of Laboratory Results With Hiv-Infected Patients In Rural Uganda: A Cross-Sectional Survey Study, Mark J. Siedner, Jessica E. Haberer, Mwebesa B. Bwana, Norma C. Ware, David Bangsberg

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Patient-provider communication is a major challenge in resource-limited settings with large catchment areas. Though mobile phone usership increased 20-fold in Africa over the past decade, little is known about acceptability of, perceptions about disclosure and confidentiality, and preferences for cell phone communication of health information in the region.

Methods: We performed structured interviews of fifty patients at the Immune Suppression Syndrome clinic in Mbarara, Uganda to assess four domains of health-related communication: a) cell phone use practices and literacy, b) preferences for laboratory results communication, c) privacy and confidentiality, and d) acceptability of and preferences for text messaging to …

Technical Desiderata For The Integration Of Genomic Data Into Electronic Health Records., Daniel R Masys, Gail P Jarvik, Neil F Abernethy, Nicholas R Anderson, George J Papanicolaou, Dina N Paltoo, Mark A Hoffman, Isaac S Kohane, Howard P Levy

Manuscripts, Articles, Book Chapters and Other Papers

The era of "Personalized Medicine," guided by individual molecular variation in DNA, RNA, expressed proteins and other forms of high volume molecular data brings new requirements and challenges to the design and implementation of Electronic Health Records (EHRs). In this article we describe the characteristics of biomolecular data that differentiate it from other classes of data commonly found in EHRs, enumerate a set of technical desiderata for its management in healthcare settings, and offer a candidate technical approach to its compact and efficient representation in operational systems.
