Full textAbstract:
This dissertation deals with three problems in health care. In the first, we consider the incentives to change prices and capital levels at hospitals, using optimal control under the assumption that private payers charge higher prices if patients consume more hospital services. The main results are that even with fixed technology, investment and prices exhibit explosive growth, and that prices and capital stock grow in proportion to one another.
In the second chapter, we study the flow of nosocomial infections in an intensive care unit. We use data from Cook County Hospital, along with numerous results from the literature, to construct a discrete event simulation. This model highlights emergent properties from treating the flow of patients and pathogens in one interconnected system, and sheds light on how nosocomial infections relate to hospital costs. We find that the system is not decomposable to individual systems, exhibiting behavior that would be difficult to explain in isolation.
In the third chapter, we analyze a proposed change in diversion policies at hospitals, in order to increase the number of patients served, without an increase in resources. Overcrowding in hospital emergency departments is caused in part by the inability to send patients to main hospital wards, due to limited capacity. When a hospital is completely full, the hospital often goes on ambulance diversion, until some spare capacity has opened up. Diversion is costly, and often leads to waves of diversions in systems of hospitals, a situation that is regarded as highly problematic in public health. We construct and analyze a continuous-time Markov chain model for one hospital. The intuition behind the model is that load-balancing between various hospitals in a metro area may hinder full congestion. We find that a more flexible contract may benefit all parties, through the partial diversion of federally insured patients, when a hospital is very close to full. Discrete event simulation models are run to assess the effect, using data from DeKalb Medical Center, and also to show that in a two-hospital system, more federally insured patients are served using this mechanism.

Full textAbstract:
Electronic patient records, containing data about the health and care of a patient, are a valuable source of information for longitudinal clinical studies. The General Practice Research Database (GPRD) has collected patient records from UK primary care practices since the late 1980s. These records contain both structured data (in the form of codes and numeric values) and free text notes. While the structured data have been used extensively in clinical studies, there are significant practical obstacles in extracting information from the free text notes. The main obstacles are data access restrictions, due to the presence of sensitive information, and the specific language of medical practitioners, which renders standard language processing tools ineffective. The aim of this research is to investigate approaches for computer analysis of free text notes. The research involved designing a primary care text corpus (the Harvey Corpus) annotated with syntactic chunks and clinically-relevant semantic entities, developing a statistical chunking model, and devising a novel method for applying machine learning for entity recognition based on chunk annotation. The tools produced would facilitate reliable information extraction from primary care patient records, needed for the development of clinically-related research. The three medical concept types targeted in this thesis could contribute to epidemiological studies by enhancing the detection of co-morbidities, and better analysing the descriptions of patient experiences and treatments. The main contributions of the research reported in this thesis are: guidelines for chunk and concept annotation of clinical text, an approach to maximising agreement between human annotators, the Harvey Corpus, a method for using a standard part-of-speech tagging model in clinical text chunking, and a novel approach to recognising clinically relevant medical concepts.

Full textAbstract:
Social media are dynamic tools that have allowed virtual socialization and dialogue to emerge on the Internet. Although the term is often used synonymously with social networking and web 2.0, social media have penetrated intra-personal and professional communication extensively and their use has become essentially tacit knowledge among teenagers, and increasingly in the general population. To date, the value of social media to health professionals as a tool for clinical activity and in public health has not been extensively studied.
Blogs, Facebook, Twitter, Wikipedia, YouTube, Flickr, Mashups and Second Life are no longer obscure words in the vocabularies of highly technical people. These spaces are starting to replace face-to-face interaction in a large majority of populations and institutions.
Healthcare has not been isolated from this trend. The evidence base for the use of social media is rising exponentially, with applications in medical education, collaboration, surveillance, clinical trials, public health, and health services research. However, the comprehensive documentation of how, where and why these tools are affecting health(care) is not well documented.
This thesis provides a comprehensive review of the impact of social media in medicine and health(care). Chapter 1 provides an overview of the conceptual and theoretical frameworks, along with the assumptions, that guide the use of social media in the health domain. Chapter 2 synthesizes the what, where, when, how and why social media are being adopted, structured according to the different functionalities of social media. These include blogs, microblogs, social networking, professional and thematic networking, wikis, media sharing tools, mashups, collaborative filtering/bookmarking and other social media (e.g., Second Life). Chapter 2 also discusses a series of clinical implications and recommendations for stakeholders wishing to engage these dynamic spaces. Chapter 3 reviews three recent administrative and judicial cases that have emerged from the inappropriate use of social media and Chapter 4 concludes with the main implications of and significance of the findings. Further research is clearly required to solidify the evidence on the use of social media in health care and to explore and document its economic, clinical, governance and tactical impact and utility.

Couch, Heather C. "Providers' Acceptance of Smartphone Applications as a Supportive Strategy for Adolescent Asthma." Thesis, The University of Arizona, 2017. http://pqdtopen.proquest.com/#viewpdf?dispub=10273717.
Full textAbstract:
US asthma prevalence increased by five million in the last decade and health care spending for the disease increased from $53 billion to $56 billion. Children are more likely than adults to have an asthma attack and its estimated that 1-in-10 youth has asthma. Despite initiatives to promote adherence to practice guidelines, childhood asthma emergency room) visits, and hospitalizations remain steady while the number of asthma deaths have increased over a 17-year period. Preliminary studies find the majority of adolescents prefer smartphones as a means of education and guidance. A modified Technology Acceptance Model (TAM) survey was comprised of 15 statements that explored providers’ acceptance of smartphone applications (apps) as an adjunct strategy for management of asthma among adolescents in the outpatient setting. Current insight in adolescent asthma demonstrates multifaceted disparities in care stemming from biological and developmental transitions unique to adolescents. The quantitative, descriptive design of the project assessed two factors integral to the TAM related to provider acceptance and perception: 1) Perceived use (PU), and 2) Perceived ease of use (PEU). The survey sample consisted of 18 providers. Overwhelmingly, the majority of providers surveyed favored use of a smartphone app for adolescent asthma and believed apps had the potential to improve the quality of adolescent asthma management. Most participants agreed; smartphone apps might help accomplish benchmarks for adolescent asthma management. Numerous studies demonstrate adolescents’ preference for technological interventions for self-management of their asthma symptoms. The survey results reinforce the willingness of providers to accept asthma smartphone apps as a potential adjunct management strategy for adolescent asthma. Additional studies involving providers are required to further explore provider attitudes of acceptance and rejection relating to smartphone apps for chronic health conditions.

Developing native applications for different platforms with different resolutions and screen sizes is both time consuming and costly. If developers were able to develop one web based application which can be used on multiple platforms, yet retain the same level of security as a native application, they would be able to reduce both development time and costs. In this thesis we will investigate the possibilities of achieving a level of security in a web-based application that can equal that of a native application, as well as how to develop an application that uses the Mina Vårdkontakter (My Healthcare Contacts) framework.

Full textAbstract:
With the increasing elderly population and longer life expectancies, smart wearable technologies are playing an important role in facilitating caregivers to monitor elderly people remotely. Aifloo’s wristband is one smart wristband which can collect various data, predict activities and detect abnormalities to enable elderly people to live independently at home. However, too much information and poor visualizations will cause huge difficulties for caregivers to interpret the data. Six caregivers were interviewed in this study to investigate what data is relevant to monitor elderly people and how they interpret the different designed displays. The main results show that alarms, fall incidents and medication compliance are the most important. Besides, caregivers place a greater emphasis on holistic views of data and they want to highlight abnormal behaviors and alerts. In the end, design guidelines for the information system to present data meaningfully and intuitively are generated.Med ett ökande antal äldre och en ökande medellivslängd kommer smart, bärbar teknologi att spela en större roll i äldrevården för att övervaka de äldre. Aifloos armband är en smart teknologi som kan samla in olika former av data, förutsäga aktiviteter och upptäcka avvikande och onormala beteenden, vilket kan användas av äldre som bor självständiga i sena egna hem. Stora mängder data, och dåliga visualiseringar av dem, orsakar svårigheter för vårdgivare att tolka datan. I den här studien har sex vårdgivare intervjuats för att utforska vilken data som är relevant för dem, och hur de kan tolka information ifrån en grupp olika gränssnitt. Studiens resultat visar att alarm, fallolyckor och översikt över hur de äldre efterföljer sina medicinska recept är viktigast. Vårdgivarna lägger en större vikt vid att förstå datan holistiskt, och de vill synliggöra avvikande beteendemönster och varningar. Slutgiltligen presenteras riktlinjer för hur IT-system kan designas för att presentera data på ett meningsfullt och intuitivt vis.

The Remote Consultation and Diagnosis (RCD) in Global Picture Archiving and Communication System (Global PACS) is a unique suite of multimedia telemedicine applications developed at the University of Arizona. The applications support real-time patients' data, image files, audio and video consultation and diagnosis annotation exchanges. The RCD enables joint collaboration between pathologists, radiologists, or physicians while they are at distant geographical locations. This project provides four RCD scenarios, i.e., Case Review, Case Acquire, Store and Forward Analysis, as well as Interactive Diagnosis and Consultation. The RCD Global PACS environment consists of heterogeneous, autonomous, and legacy resources. The Common Object Request Broker Architecture (CORBA), Java Database Connectivity (JDBC), and Java language provide the capability to combine the RCD Global PACS resources into an integrated, interoperable, and scalable system. The underneath technology, including IDL, ORB, Event Service, IIOP, JDBC/ODBC, legacy system wrapping and Java implementation are explored. This distributed collaborative CORBA/JDBC based framework will challenge the advanced, medical information management requirements. It also makes the RCD Global PACS both hardware and software technologically independent. As our research and development extend, we will continue to incorporate the latest advances in computer technology. RCD Global PACS is not another new tool in telemedicine, but rather a new paradigm for the delivery of health services that requires process reengineering, cultural changes, as well as organizational changes. It is a whole new way of practicing in telemedicine. We ensure that the RCD Global PACS project has long-term, comprehensive solutions for today and tomorrow's healthcare needs.

Hernandez, Helen Birkmann. "Usability Challenges with Insulin Pump Devices in Diabetes Care: What Trainers Observe with First-Time Pump Users." Diss., NSUWorks, 2019. https://nsuworks.nova.edu/gscis_etd/1087.
Full textAbstract:
Insulin pumps are designed for the self-management of diabetes mellitus in patients and are known for their complexity of use. Pump manufacturers engage trainers to teach patients how to use the devices correctly to control the symptoms of their disease. Usability research related to insulin pumps and other infusion pumps with first-time users as participants has centered on the relationship between user interface design and the effectiveness of task completion. According to prior research, the characteristics of system behavior in a real life environment remain elusive. A suitable approach to acquire information about potential usability problems encountered by first-time users is to obtain this information from the health care professionals who train them.
The purpose of the study was to discover the lived experiences and shared impressions of insulin pump trainers during training sessions with first-time users. Interpretative Phenomenological Analysis (IPA) was used to uncover the phenomena associated with usability challenges that first-time users of insulin pumps face when learning to use the device. Six participants representing a homogeneous sample were recruited from a wide geographic area in the United States, and semi-structured interviews containing open-ended questions were conducted with the respondents.
The data from the lived experiences and shared impressions of the participants were used to develop the following five super-ordinate themes: Emotion-charged Environment, Personalized Training, Safety Issues and Disaster Planning, Professional Dedication, and The Voice. The essence of participants’ experience was described around the pivotal moment when the training sessions are successfully completed and insulin pump therapy becomes alive.
The findings of this study have implications for information systems professionals who conduct research on the safe design and usability of safety critical medical devices. In addition, the findings from this study create opportunities for practice to improve the initiation of insulin pump therapy in patients with diabetes.

Full textAbstract:
The major socio-economic development challenges facing most African countries include economic diversification, poverty, unemployment, diseases and the unsustainable use of natural resources. The challenge of quality healthcare provisioning is compounded by the HIV/AIDS pandemic in Sub Saharan Africa. However, there is a great potential in using electronic healthcare (e-health) as one of the supportive systems within the healthcare sector to address these pressing challenges facing healthcare systems in developing countries, including solving inequalities in healthcare delivery between rural and urban hospitals/clinics. The purpose of this study was to compile a Provincial E-health Framework (PEHF) based on the feedback from electronic healthcare readiness assessments conducted in selected rural and urban hospitals/clinics in the North West Province in South Africa. The e-healthcare readiness assessment was conducted in the light of effective use of ICT in patient healthcare record system, consultation among healthcare professionals, prescription of medication, referral of patients and training of healthcare professionals in ICT usage. The study was divided into two phases which were phases 1 and 2 and a qualitative design supported by a case study approach was used. Data were collected using different techniques to enhance triangulation of data. The techniques included group interviews, qualitative questionnaires, photographs, document analysis and expert opinions. The outcome of the assessment led to the compilation of the PEHF which was based on Service Oriented Architecture (SOA). SOA was chosen to integrate the hospitals/clinics‟ ICT infrastructure yet allowing each hospital/clinic the autonomy to control its own ICT environment. To assist hospitals/clinics integrate their ICT resources, this research study proposed an Infrastructure Network Architecture which clustered hospitals/clinics to share common ICT infrastructure instead of duplicating these resources. Furthermore, processes of the e-health services (e-patient health IV record system, e-consultation system, e-prescription system, e-referral system and e-training system) were provided to assist in the implementation of the PEHF. Finally, a set of guidelines were provided by the research study to aid the implementation of the PEHF.

Full textAbstract:
In the present study, a 8 x 4 mm biodegradable device was formulated using poly(ortho ester) and metronidazole for treatment of periodontitis. Investigation focussed upon determination of formulation parameters in the form of drug (metronidazole) and adjuvant concentrations (oleic acid and palmitic acid) and device thickness necessary to achieve constant release of 0.6 μg/hr over a period of 7 days and complete degradation of the device over a period of 11 to 13 days. Presence of oleic or palmitic acid influenced the release and erosion profile considerably. Thickness of the device did not have significant influence on the drug release. The DSC and NMR studies indicated absence of interaction between drug and polymer. Computer optimization studies indicate that the optimum formulation for 7 day constant drug delivery and disappearance in 13 days should contain 0.28% w/w of oleic acid and 5.26% w/w of metronidazole at the thickness of 400-450 or 500-550 μm. This is in close agreement with the optimum formulation which was obtained with the experimental data.

Full textAbstract:
The overall aim of the research is to develop a computational platform based on HINT paradigm for manipulating, predicting and analyzing biomacromolecular-ligand structure. A second synergistic goal is to apply the above methodology to design novel and potent anti-cancer agents. The crucial role of the microtubule in cell division has identified tubulin as an interesting target for the development of therapeutics for cancer. Pyrrole-containing molecules derived from nature have proven to be particularly useful as lead compounds for drug development. We have designed and developed a series of substituted pyrroles that inhibit growth and promote death of breast tumor cells at nM and μM concentrations in human breast tumor cell lines. In another project, stilbene analogs were designed and developed as microtubule depolymerizing agents that showed anti-leukemic activity. A molecular modeling study was carried out to accurately represent the complex structure and the binding mode of a new class of tubulin inhibitors that bind at the αβ-tubulin colchicine site. These studies coupled with HINT interaction analyses were able to describe the complex structure and the binding modes of inhibitors. Qualitative analyses of the results showed general agreement with the experimental in vitro biological activity for these derivatives. Consequently, we have been designing new analogs that can be synthesized and tested; we believe that these molecules will be highly selective against cancer cells with minimal toxicity to the host tissue. Another goal of our research is to develop computational tools for drug design. The development and implementation of a novel cavity detection algorithm is also reported and discussed. The algorithm named VICE (Vectorial Identification of Cavity Extents) utilizes HINT toolkit functions to identify and delineate a binding pocket in a protein. The program is based on geometric criteria and applies simple integer grid maps to delineate binding sites. The algorithm was extensively tested on a diverse set of proteins and detects binding pockets of different shapes and sizes. The study also implemented the computational titration algorithm to understand the complexity of ligand binding and protonation state in the active site of HIV-1 protease. The Computational titration algorithm is a powerful tool for understanding ligand binding in a complex biochemical environment and allows generating hypothesis on the best model for binding.

Bazile, Emmanuel Patrick. "Electronic Medical Records (EMR): An Empirical Testing of Factors Contributing to Healthcare Professionals’ Resistance to Use EMR Systems." NSUWorks, 2016. http://nsuworks.nova.edu/gscis_etd/964.
Full textAbstract:
The benefits of using electronic medical records (EMRs) have been well documented; however, despite numerous financial benefits and cost reductions being offered by the federal government, some healthcare professionals have been reluctant to implement EMR systems. In fact, prior research provides evidence of failed EMR implementations due to resistance on the part of physicians, nurses, and clinical administrators. In 2010, only 25% of office-based physicians have basic EMR systems and only 10% have fully functional systems. One of the hindrances believed to be responsible for the slow implementation rates of EMR systems is resistance from healthcare professionals not truly convinced that the system could be of substantive use to them.
This study used quantitative methods to measure the relationships between six constructs, namely computer self-efficacy (CSE), perceived complexity (PC), attitude toward EMR (ATE), peer pressure (PP), anxiety (AXY), and resistance to use of technology (RES), are predominantly found in the literature with mixed results. Moreover, they may play a significant role in exposing the source of resistance that exists amongst American healthcare professionals when using Electronic Medical Records (EMR) Systems. This study also measured four covariates: age, role in healthcare, years in healthcare, gender, and years of computer use. This study used Structural Equation Modeling (SEM) and an analysis of covariance (ANCOVA) to address the research hypotheses proposed. The survey instrument was based on existing construct measures that have been previously validated in literature, however, not in a single model. Thus, construct validity and reliability was done with the help of subject matter experts (SMEs) using the Delphi method. Moreover, a pilot study of 20 participants was conducted before the full data collection was done, where some minor adjustments to the instrument were made. The analysis consisted of SEM using the R software and programming language.
A Web-based survey instrument consisting of 45 items was used to assess the six constructs and demographics data. The data was collected from healthcare professionals across the United States. After data cleaning, 258 responses were found to be viable for further analysis. Resistance to EMR Systems amongst healthcare professionals was examined through the utilization of a quantitative methodology and a cross-sectional research measuring the self-report survey responses of medical professionals. The analysis found that the overall R2 after the SEM was performed, the model had an overall R2 of 0.78, which indicated that 78% variability in RES could be accounted by CSE, PC, ATE, PP, and AXY. The SEM analysis of AXY and RES illustrated a path that was highly significant (β= 0.87, p < .001), while the other constructs impact on RES were not significant. No covariates, besides years of computer use, were found to show any significance differences.
This research study has numerous implications for practice and research. The identification of significant predictors of resistance can assist healthcare administrators and EMR system vendors to develop ways to improve the design of the system. This study results also help identify other aspects of EMR system implementation and use that will reduce resistance by healthcare professionals. From a research perspective, the identification of specific attitudinal, demographic, professional, or knowledge-related predictors of reference through the SEM and ANCOVA could provide future researchers with an indication of where to focus additional research attention in order to obtain more precise knowledge about the roots of physician resistance to using EMR systems.

Schladen, Manon Maitland. "Formative Research on an Instructional Design Theory for Virtual Patients in Clinical Education: A Pressure Ulcer Prevention Clinical Reasoning Case." NSUWorks, 2015. http://nsuworks.nova.edu/gscis_etd/35.
Full textAbstract:
Despite advances in health care over the past decades, medical errors and omissions remain significant threats to patient safety and health. A large number of these mistakes are made by trainees, persons who are just beginning to build the case-based experiences that will transform them from novices to expert practitioners. Clinicians use both intuitive and deductive problem-solving skills in caring for patients and they acquire expertise in applying these skills through interaction with many and varied cases.
The contemporary heath care environment, with decreased lengths of stay for patients and reduced duty hours for trainees, makes getting optimal patient exposure difficult. Virtual patients (VPs), online, interactive patient cases, may help close the case exposure gap. Evidence has shown that VPs improve clinical reasoning skills, but no formal instructional design theory of VPs has been advanced. The goal was to conduct formative research to develop an instructional design theory of VPs to help novice clinicians cultivate clinical reasoning and diagnostic skills. The instructional design theory, goal-based scenarios (GBS), grounded in the learning theory, Case-based Reasoning, provided methods that promised to be appropriate to the goal.
An existing, two-module, multimedia VP, Matt Lane, A Pressure Ulcer Prevention Virtual Patient, was tested with 10 medical trainees to determine which methods of GBS it incorporated and which of its methods were not part of GBS. Leaners' experience of what worked and didn't work to promote learning in the VP was analyzed. The VP was found to incorporate all GBS methods and one significant method, the Life Model, that was not part of GBS. The Life Model Method involved replicating, with a high degree of fidelity, the experiences of a real patient in creating the VP scenario.
Recommendations for customization of GBS for VPs included more explicit advertisement of learning goals and leverage of Internet search engines to provide just-in-time resources to support problem-solving. Incorporation of the Life Model was also recommended along with the Simplifying Conditions Method from Elaboration Theory to manage the complexity inherent in the Life Model. The resultant, enhanced GBS theory may be particularly relevant in teaching patient-centered care.

Full textAbstract:
Recent advances in information and communication technologies have made the development and operation of complex disease surveillance systems technically feasible, and many systems have been proposed to interpret diverse data sources for health-related signals. Implementing these systems for daily use and efficiently interpreting their output, however, remains a technical challenge. This thesis presents a method for understanding disease surveillance systems structurally, examines four existing systems, and discusses the implications of developing such systems. The discussion is followed by two papers. The first paper describes the design of a national outbreak detection system for daily disease surveillance. It is currently in use at the Swedish Institute for Communicable Disease Control. The source code has been licenced under GNU v3 and is freely available. The second paper discusses methodological issues in computational epidemiology, and presents the lessons learned from a software development project in which a spatially explicit micro-meso-macro model for the entire Swedish population was built based on registry data.QC 20110520

Full textAbstract:
As the bulk of medical health records shift from paper-based file systems to electronic formats, the promise of the transformation process called healthcare reform included adding efficiencies to medical practice workflows, lower costs, improved quality of care and most important, and the freeing of patient information from traditional propriety silos. With this incoming largess of protected health information data now viewable through online patient portals, patients can be empowered to become educated and active in their own health care decisions, but only if they have admission to their information. A digital divide currently exists in many medical practices where only a very few patients have access to their personal health information. The primary goal was to facilitate organizational change needed for physician-managed practices to increase patient adoption and meaningful use of patient portals for secure communication, wellness education, review of labs and other tests, and receipt of clinical summaries.
The methodology utilized the appreciative inquiry 4-D model as the underlying basis of three phases: Phase 1-fundamental study, Phase 2-strategic action plan, and Phase 3 supporting organizational change. The physicians or providers in independent medical practices are the key determinate of the organizational workflows.
The results have added significantly to the understanding of organizational change as related to patient engagement and the adoption and meaningful use of patient portals in independent physician-managed clinics. As medical practices and their physician leaders raise patient portal workflow processes to a higher level of importance, it is expected that patients will begin to adopt these procedures as their preferred methods and bring about a change in the patient-provider relationship.

McDaniel, James Grennell. "Health link: a wide area telecommunication network for health care providers." Thesis, 1994. https://dspace.library.uvic.ca//handle/1828/9670.
Full textAbstract:
Early computerized health information systems supported applications in hospital records and laboratory data collection. Since that time, software has been developed for a number of health care providers such as doctors and pharmacists. Although local area networks are installed at larger institutions, only a few small-scale, special-purpose, wide-area networks are installed for external providers. To be adopted, wide-area networks should provide greater functionality than, and be cost-competitive with, conventional communication methods. Several projects are underway in Health Information Science to develop and evaluate generic, wide-area networks.
This dissertation describes the design, analysis, development, implementation and evaluation of a prototype health care network which would be accessible to providers using existing computer equipment and the public switched telephone system. The network software, Health Link, supports reliable, automatic, store-and-forward messaging of medically-sensitive information. Encrypted messages can be authenticated and the software features registered delivery. An application programming interface formats messages in accordance with the HL7 data interchange standard.
Simulation studies have been conducted which demonstrate the steady state characteristic behaviour of a node in a uniform cluster. Further studies have investigated a realistic, dynamic, large scale network. A peer-to-peer model and client-server model were analyzed and both were found to be feasible with respect to certain performance and cost criteria. The client-server model was found to be less costly to operate than the peer-to-peer model. The peer-to-peer model can transfer messages in a shorter time than the client-server model.
The network software was verified in a field test involving four clinics, one medical laboratory, and one hospital. Data collected in the test provide performance benchmarks, an estimate of message sizes and frequencies, network reliability statistics, and a wealth of observations. Performance benchmarks and message traffic measurements were used to calibrate the simulation models.
Results from this and other research indicate that, although most of the technical networking problems can be readily overcome, consensus on standards, health care applications, and initiatives should be promoted before a wide-spread, production network is implemented.Graduate

Indiana University-Purdue University Indianapolis (IUPUI)The reliability of information in health social network sites (HSNS) is an imperative concern since false information can cause tremendous damage to health consumers. In this thesis, we introduce a trust framework which captures both human trust level and its uncertainty, and also present advantages of using the trust framework to intensify the dependability of HSNS, namely filtering information, increasing the efficiency of pharmacy marketing, and modeling how to monitor reliability of health information. Several experiments which were conducted on real health social networks validate the applicability of the trust framework in the real scenarios.

Full textAbstract:
abstract: The technological revolution has caused the entire world to migrate to a digital environment and health care is no exception to this. Electronic Health Records (EHR) or Electronic Medical Records (EMR) are the digital repository for health data of patients. Nation wide efforts have been made by the federal government to promote the usage of EHRs as they have been found to improve quality of health service. Although EHR systems have been implemented almost everywhere, active use of EHR applications have not replaced paper documentation. Rather, they are often used to store transcribed data from paper documentation after each clinical procedure. This process is found to be prone to errors such as data omission, incomplete data documentation and is also time consuming. This research aims to help improve adoption of real-time EHRs usage while documenting data by improving the usability of an iPad based EHR application that is used during resuscitation process in the intensive care unit. Using Cognitive theories and HCI frameworks, this research identified areas of improvement and customizations in the application that were required to exclusively match the work flow of the resuscitation team at the Mayo Clinic. In addition to this, a Handwriting Recognition Engine (HRE) was integrated into the application to support a stylus based information input into EHR, which resembles our target users’ traditional pen and paper based documentation process. The EHR application was updated and then evaluated with end users at the Mayo clinic. The users found the application to be efficient, usable and they showed preference in using this application over the paper-based documentation.Dissertation/Thesis

Full textAbstract:
D.Litt. et Phil.The practice of medicine changes constantly and rapidly. Consequently, it is difficult for clinicians to learn about innovations, given the vast quantity of information available. Evidence-based medicine (EBM) is the process by which practitioners turn clinical problems into questions, and then systematically integrate personal clinical expertise with the best available external evidence as the basis for clinical decisions. To practice EBM, the practitioner is required to search the literature for relevant material, and then to synthesise knowledge and apply findings to each patient. Clinicians require fast and specific access to multiple data sources, but the availability of electronic full text documents has substantially exacerbated the lack of time to read the clinical literature owing to the demands of clinical practice, and is further compounded by the fact that the Web contains much health-related misinformation. Clinicians therefore require a means of searching the literature that will enhance the retrieval of accurate and evaluated clinical data from ranked resources, whereby the most relevant information is retrieved first from the most likely source. Strong correlations exist between four primary steps in EBM, and the formula commonly used in search strategy design in the field of information seeking. The similarities inherent in these steps suggest that an evidence-based approach to information seeking might enable endusers in the health professions to enhance their searching skills and to translate the clinical question into an appropriate information-seeking strategy. A main problem and two sub-problems were investigated, namely whether: · a Web-based EBM information-seeking model could be designed to enhance the information-seeking skills of healthcare practitioners · it was possible to design an information-seeking model more closely aligned with the clinical decision-making model familiar to healthcare practitioners · it was possible to design such a model in a manner that could further enhance the translation of the clinical question into an appropriate information-seeking strategy. Various models in medicine and the domain of information seeking were investigated. It was found that the model of the clinical decision-making process accorded with all six phases of the information-seeking process (ISP), whereas other information-seeking models only addressed the ISP from the formulation of the problem onwards, thus ignoring prior stages of initiation, selection and exploration in the ISP. A Web-based EBM information-seeking model (Model C) was devised and tested for compatibility against a general Web-based information-seeking model, and was found to be valid. Model C was further empirically assessed against a Web site design methodology, and was again found to be compatible. A unique approach to EBM information seeking is thus offered by Model C, which incorporates all aspects of the clinical-decision-making metaphor, as well as the “PICO” EBM filters (Patient/Problem, Intervention, Comparative Intervention and Outcome), into a facet analysis template for the design of a clinical search strategy. Prior to selection of the EBM information resource, Model C further allows for the ranking of each resource and for the design of individual browsing and/or analytical search strategies, as appropriate, so as to enhance EBM information seeking amongst healthcare practitioners.

Full textAbstract:
Indiana University-Purdue University Indianapolis (IUPUI)Reducing medical error remains in the forefront of healthcare reform. The use of health information technology, specifically the electronic health record (EHR) is one attempt to improve patient safety. The implementation of the EHR in the Emergency Department changes physician workflow, which can have negative, unintended consequences for patient safety. Inaccuracies in clinical documentation can contribute, for example, to medical error during transitions of care. In this quasi-experimental comparison study, we sought to determine whether there is a difference in document quality, error rate, error type, cognitive load and time when Emergency Medicine (EM) residents use paper charts versus the EHR to complete physician documentation of clinical encounters. Simulated patient encounters provided a unique and innovative environment to evaluate EM physician documentation. Analysis focused on examining documentation quality and real-time observation of the simulated encounter. Results demonstrate no change in document quality, no change in cognitive load, and no change in error rate between electronic and paper charts. There was a 46% increase in the time required to complete the charting task when using the EHR. Physician workflow changes from partial documentation during the patient encounter with paper charts to complete documentation after the encounter with electronic charts. Documentation quality overall was poor with an average of 36% of required elements missing which did not improve during residency training. The extra time required for the charting task using the EHR potentially increases patient waiting times as well as clinician dissatisfaction and burnout, yet it has little impact on the quality of physician documentation. Better strategies and support for documentation are needed as providers adopt and use EHR systems to change the practice of medicine.
