Approaches To The Spatial Modelling Of Cancer Incidence And Mortality In Metropolitan Perth, Western Australia, 1990 -2005, Changying Shao

Theses: Doctorates and Masters

Cancer is one of potentially preventable and treatable diseases. Cancer analysis from different perspectives is necessary to provide the information for health research and the initiation of prevention and treatment programs. The purpose of this study was to analyse five top cancers in the Perth metropolitan area, including lung, melanoma, breast, prostate and colorectal cancers, using two methodologies: Area-to-Point Poisson (ATP) kriging and fitting an inhomogeneous Poisson process model using the Berman-Turner algorithm. ATP Poisson kriging was used to undertake the analysis on the spatial distribution of cancer rates per 100,000 person-years for Perth Statistical Local Areas during the period …

Lateral Blood Flow Velocity Estimation Based On Ultrasound Speckle Size Change With Scan Velocity, Tiantian Xu, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Conventional (Doppler-based) blood flow velocity measurement methods using ultrasound are capable of resolving the axial component (i.e., that aligned with the ultrasound propagation direction) of the blood flow velocity vector. However, these methods are incapable of detecting blood flow in the direction normal to the ultrasound beam. In addition, these methods require repeated pulse-echo interrogation at the same spatial location. A new method has been introduced which estimates the lateral component of blood flow within a single image frame using the observation that the speckle pattern corresponding to blood reflectors (typically red blood cells) stretches (i.e., is smeared) if the …

Data Segmentation In Electronic Health Information Exchange: Policy Considerations And Analysis, Melissa M. Goldstein, Alison L. Rein, Melissa M. Heesters, Penelope P. Hughes, Benjamin Williams, Scott A. Weinstein

Health Policy and Management Faculty Publications

The issue of whether and, if so, to what extent patients should have control over the sharing or withholding of their health information represents one of the foremost policy challenges related to electronic health information exchange. It is widely acknowledged that patients' health information should flow where and when it is needed to support the provision of appropriate and high-quality care. Equally significant, however, is the notion that patients want their needs and preferences to be considered in the determination of what information is shared with other parties, for what purposes, and under what conditions. Some patients may prefer to …

Electronic Medical Records: Is It Working In Long Term Health Care?, Krista Phillips, Chris Wheeler, Josh Campbell, Alberto Coustasse

Management Faculty Research

Long-term care (LTC) facilities possess unique characteristics in terms of implementation and utilization of electronic medical records (EMRs). The focus of LTC is on a population requiring care encompassing all aspects associated with quality of life rather than simply acute treatment. Because this focus is of a larger scale than traditional medical facilities, the priorities in the implementation and utilization of EMRs are higher in accessing patient history information. The purpose of this study was to determine the EMR utilization in the chronic care settings. In conclusion, the literature review performed does not support the fact that EMRs are currently …

Medially: A Provenance-Aware Remote Health Monitoring Middleware, Atanu Roy Chowdhury, Ben Falchuk, Archan Misra

Research Collection School Of Computing and Information Systems

This paper presents MediAlly, a middleware for supporting energy-efficient, long-term remote health monitoring. Data is collected using physiological sensors and transported back to the middleware using a smart phone. The key to MediAlly's energy efficient operations lies in the adoption of an Activity Triggered Deep Monitoring (ATDM) paradigm, where data collection episodes are triggered only when the subject is determined to possess a specified context. MediAlly supports the on-demand collection of contextual provenance using a novel low-overhead provenance collection sub-system. The behaviour of this sub-system is configured using an application-defined context composition graph. The resulting provenance stream provides valuable insight …

If You Build It They Will Come: Growth Of An Online Community For Intensive Care In Australia, K Rolls, D Kowal, Margaret M. Hansen Edd, Msn, Rn, D Elliott

Nursing and Health Professions Faculty Research and Publications

Rolls, K., Kowal, D., Hansen, M., Group learning and networking are integral to contemporary views of organisational and knowledge management, and learning. Current healthcare structures however create practice silos that promote professional isolation and limit the flow and uptake of knowledge. Computer mediated communication (CMC) technologies transcend time and geography, enabling clinicians to communicate and interact with a broad range of colleagues continuously. This contrasts with traditional approaches to networking that rely on limited personal contacts and/or professional events. In 2003 the NSW Intensive Care Coordination and Monitoring Unit established ‘ICUConnect’, a listserv to network intensive care (IC) clinicians. Initially …

Computerized Provider Order Entry Implementation: Provider And Hospital Leadership Impacts On Success, Elizabeth J. Walker

Theses and Graduate Projects

Healthcare organizations are consistently exhausting efforts to improve their patient safety standards and outcomes, especially those that are regulated by federal and state agencies. Many healthcare organizations have chosen to implement an Electronic Health Record (EHR) to facilitate better decision-making and faster tumaround for providers, thus improving patient safety. The EHR allows providers to manage patient care with the help of decision support functions, and with greater accessibility to the patient's information. One of the components of an EHR is the application of Computerized Provider Order Entry (CPOE). Although the benefits to both providers and patients have shown to be …

Use Of Emoticons For Assessing Emotion And Mood States In Web-Based Interventions, Jennifer Chua So

Loma Linda University Electronic Theses, Dissertations & Projects

In the rapidly growing field of online psychotherapeutic interventions, an increasing number of clinicians are seeking to extend therapeutic interventions into cyberspace. However, because communication with clients in this medium is often devoid of auditory and visual feedback, these clinicians are not able to rely on their clinical observations. It then becomes incumbent to develop a psychometrically and theoretically sound means of assessing emotion and mood states that can be easily utilized in this forum. Utilizing cross-culturally and empirically supported models of emotion structure shown to be influential in the self-report data, the Positive Affect and Negative Affect factors, this …

The Effects Of The Introduction Of An Electronic Medical Record (Emr) On Self-Reported Treatment Effects In A Psychological Service In A Family Medicine Clinic, Michael D. Herman

Loma Linda University Electronic Theses, Dissertations & Projects

The healthcare system in the United States has traditionally focused on pathogenic disease prevention and treatment of acute illness, only addressing physical health (Grzywacz & Keyes, 2004). This approach is limited, as it does not often acknowledge the influence of mental health and health promotion on outcomes. Approximately, 25-75% of all presenting cases with uncertain etiology in medicine are psychosocial or behavioral in origin (Schulte et. al., 2004). Improvements can be made through integrated care; however, divergent viewpoints and often proximity across providers disrupts, psychologist-physician communication, collaboration, and subsequently care access (McDaniel, 1995). The current study examines the self reported …

Resolving The Lateral Component Of Blood Flow Velocity Based On Ultrasound Speckle Size Change With Scan Direction And Speed, Tiantian Xu, Greg R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Conventional blood flow velocity measurement using ultrasound is capable of resolving the axial component (i.e., that aligned with the ultrasound propagation direction) of the blood flow velocity vector. However, these Doppler-based methods are incapable of detecting blood flow in the direction normal to the ultrasound beam. In addition, these methods require repeated pulse-echo interrogation at the same spatial location. In this paper, we introduce a method which estimates the lateral component of blood flow within a single image frame using the observation that the speckle pattern corresponding to the blood reflectors (typically red blood cells) stretches (i.e., is “smeared”) if …

Further Progress On Lateral Flow Estimation Using Speckle Size Variation With Scan Direction, Tiantian Xu, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Conventional blood flow velocity measurement using ultrasound is capable of resolving the axial component (i.e., that aligned with the ultrasound propagation direction) of the blood flow velocity vector. However, these Doppler-based methods are incapable of detecting blood flow in the direction normal to the ultrasound beam. In addition, these methods require repeated pulse-echo interrogation at the same spatial location. In this paper, we report additional data on a new method recently introduced. This method estimates the lateral component of blood flow within a single image frame using the observation that the speckle pattern corresponding to the blood reflectors (typically red …

Single Molecule Diffusion Coefficient Estimation By Image Analysis Of Simulated Ccd Images To Aid High-Throughput Screening, Pengfei Song, Lloyd M. Davis, Greg Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Extension of one-dimensional signal analysis to two-dimensional image analysis could accelerate conventional methods of high-throughput screening in the discovery of new pharmaceutical agents. This work describes a first step taken towards this goal – the evaluation of image-analysis based estimation strategies of the diffusion coefficient of a single molecule transported within a microfabricated flowcell. A computer simulation of single-molecule imaging by a charge-coupled device (CCD) camera is used to determine if it is possible to distinguish three different types of molecules with different diffusion coefficients. The Gaussian fitting algorithm finds the variance of the transverse trajectory, which increases linearly with …

Optimal Thresholds Of Feature Tracking For Blood Velocity And Tissue Motion Estimation, Tiantian Xu, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Feature tracking is an algorithm for estimating blood flow velocity and tissue motion using pulse-echo ultrasound. In contrast to cross-correlation speckle-tracking techniques, feature tracking identifies features at discrete locations and corresponds them from frame to frame. Prior studies have demonstrated that feature-tracking estimates exhibit lower variance than those obtained by the conventional autocorrelation method and require less computational complexity than either speckle tracking or autocorrelation. To date, not much attention has been paid to the process by which trackable features (normally local maxima) are selected from the set of all available features. In the selection process, it is desired to …

The Influence Of Affect, Attitude And Usefulness In The Acceptance Of Telemedicine Systems, Soussan Djamasbi,, Ann L. Fruhling, Eleanor T. Loiacono

Information Systems and Quantitative Analysis Faculty Publications

Grounded in current theories of affect this study examines the role positive and negative moods play on the acceptance of a specialized telemedicine system for microbiology consultation and diagnostics, referred to as telepathology. From a laboratory experiment using microbiology laboratory assistants, the notion that healthcare users’ attitude is an important factor in the acceptance behavior of a healthcare information system is supported. A regression analysis of the data revealed the need to tailor the IS Technology Acceptance Model for the healthcare field. Specifically, our results show that ease of use which is thought to be a main antecedent of end-user …

Predicting Patients’ Use Of Provider-Delivered E-Health: The Role Of Facilitating Conditions, E. Vance Wilson, Nancy K. Lankton

Accounting Faculty Research

This chapter presents a new rational-objective (R-O) model of e-health use that accounts for effects of facilitating conditions as well as patients’ behavioral intention. An online questionnaire measured patients’ behavioral intention to use a new e-health application as well as proxy measures of facilitating conditions that assess prior use of and structural need for health services. A second questionnaire administered three months later collected patients’ self-reported use of e-health during the intervening period. The new model increased predictions of patients’ e-health use (measured in R2) by more than 300% over predictions based upon behavioral intention alone, and all measured factors …
