Objectives: To identify the perceptions of community hospital physicians on computerized physician order entry. Design: Multi-method approach consisting of a mail survey of 659 community hospital physicians with active admitting privileges at three PeaceHealth, Inc., along with follow-up personal interviews with stratified random selection from completed survey. Measurements: Perceptions were assessed by means of a mail survey that asked physicians to rank themselves on a scale that represented the five adopter categories contained in the Diffusion of Innovation (DOI) change theory, along with several questions regarding computer use and attitudes toward potential effects of computers and CPOE on medicine and healthcare. Physicians representing four of the five adopter categories were interviewed to assess general perceptions and perceived attributes of innovations, an another construct within the DOI theory. Results: The response rate was 41%. Medical specialty, years in practice, and gender were found not to influence attitudes toward use of computers or, more specifically CPOE in medicine and healthcare. However, more medical specialists favor CPOE implementation at PeaceHealth than expected. Self-ranking on the DOI five adopter categories appears to influence attitudes toward use of computers in medicine and healthcare with positive trends in improving quality, rapport, and patient satisfaction mainly in the Innovator, Early Adopter, and Early Majority categories. A positive trend was seen in the relationship between CPOE's potential effects on improving patient care, not interfering with communication, and improving patient satisfaction with negative relationships with impact on physician workflow and enjoyment of medical practice. A relationship is seen between the five adopter categories and favoring CPOE implementation at PeaceHealth. The perceived attributes of innovations of Ease of Use, Result Demonstrability, and Visibility were supported by interview responses. Relative Advantage seemed to be supported by other questions. The concept of Compatibility was also supported. No steps of the processes of change construct within the Transtheoretical Model were identified during the interviews. Conclusions: This study appears to refute the suggestion that there might be a difference between medical specialists and surgical specialists, age, or gender in their support of computers and specifically CPOE. These data appear to support the Diffusion of Innovation theory is appropriate to consider in investigating CPOE and its diffusion among community hospital physicians. Implementing CPOE according to adopter categories would provide the option for interested physicians to use CPOE, to use CPOE on certain hospital units or patients, and to expand its use before making mandatory. Communication should be targeted toward the adopter categories rather than mass media and emphasize the perceived attributes of innovation. / Graduation date: 2004

This project was undertaken to provide the Family Practice residency evaluation committee with a better means of studying resident progress.An attempt is made herewith to describe the project so that future personnel with use of this paper and minimal use of the system manuals can continue operation of this system and accomplish the ultimate goal of the project.A talley of resident experience with pricare problems, drug categories, procedures, and use of laboratory examinations is maintained. The same computer file also stores his patient profile. The programs are written in Fortran l.0 for the DEC system at Ball State University.Ball State UniversityMuncie, IN 47306

Thermography is a useful tool for analyzing spinal nerve root irritation, but interpretation of digital infrared images is often qualitative and subjective. A new quantitative, computer-aided method for analyzing thermograms, utilizing the human dermatome map, is presented. Image processing and pattern recognition principles needed to accomplish this goal are discussed. Algorithms for segmentation, boundary detection and interpretation of thermograms are presented. An interactive, user-friendly program to perform this analysis has been developed. Due to the relatively large number of images in an exam, speed and simplicity were emphasized in algorithm development. The results obtained correlate well with clinical data and show promise for aiding the diagnosis of spinal nerve root irritation.

Though several clinical monitoring ways exist and have been applied to detect cardiac atril fibrillation (A-Fib) and other arrhythmia, these medical interventions and the ensuing clinical treatments are after the fact and costly. Current portable healthcare monitoring systems come in the form of Ambulatory Event Monitors. They are small, battery-operated electrocardiograph devices used to record the heart's rhythm and activity. However, they are not energy-aware ; they are not personalized ; they require long battery life, and ultimately fall short on delivering real-time continuous detection of arrhythmia and specifically progressive development of cardiac A-Fib. The focus of this dissertation is the design of a class of adaptive and efficient energy-aware real-time detection models for monitoring, early real-time detection and reporting of progressive development of cardiac A-Fib.... The design promises to have a greater positive public health impact from predicting A-Fib and providing a viable approach to meeting the energy needs of current and future real-time monitoring, detecting and reporting required in wearable computing healthcare applications that are constrained by scarce energy resources. / by Redjem Bouhenguel. / Thesis (Ph.D.)--Florida Atlantic University, 2012. / Includes bibliography. / Mode of access: World Wide Web. / System requirements: Adobe Reader.

Cardiac auscultation, an important part of the physical examination, is difficult for many primary care providers. As a result, diagnoses are missed or auscultatory signs misinterpreted. A reliable, automated means of interpreting cardiac auscultation should be of benefit to both the primary care provider and to patients. This paper explores a novel approach to this problem and develops an algorithm that can be expanded to include all the necessary electronics and programming to develop such a device. The algorithm is explained and its shortcomings exposed. The potential for further development is also expounded. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection
