"The Future of Telehealth: HIT Plays a Critical Role"

We stand at the brink of major changes in our system of health care. Driven by current economic conditions, major problems of access and the lack of any systems for widespread sharing of health information, both telehealth and health information technology (HIT) are being touted as potential solutions. Research studies in telehealth are continuing to gather evidence for its effectiveness and efficiency in care delivery. At the same time HIT as interoperable information systems is being promoted as a solution for improving the safety, quality and efficiency of care. This talk will put forth and defend two propositions: 1) that telehealth technologies themselves are a set of disruptive technologies that carry great potential for changing the manner in which health care is delivered and 2) telehealth cannot realize this potential without a close intergration with health information technologies that promote interoperability and health information exchange.

GIS in Health Research and Predicting Daily Pollen Levels in California Zip Codes
There are numerous examples of the interface between the environment (geography) and health.  In fact, the 'environment,' along with a 'host' and an 'agent of disease' comprise the epidemiologic triad, a fundamental component (spatial distribution) of disease.  When combined with a geographic information system (GIS) spatial studies are an emerging and exciting field in health research.  The first part of this presentation will provide an overview of spatial epidemiology, geographic information systems and their utility in analyzing health problems.  The second part will preview a 20 minute research presentation to be given at the GIS International User Conference in August ( a practice session, if you will.)  In this part of the talk I will discuss spatial methodology for predicting daily pollen levels in California zip codes.

How Do We Organize Data for Bioinformatics?
Research in biology has recently experienced a paradigm shift as it now focuses on collecting and analyzing very large amounts of data, mostly coming from genomics experiments.  Bioinformatics is one of the keys to the success of this approach, as it provides tools for organizing, analyzing and disseminating this data.  This presentation will focus on how genetic information is organized in databases and how will the concept of ontology be introduced into biological data.

Health Information Standards and the Emerging Big Science Paradigm: Cultural transitions in science, from independent investigators working in loosely federated communities, to large-scale team science, have been ongoing for the past 150 years. Physics illustrated this transition most palpably from Rutherford to Hadron colliders. Biomedical science is in the midst of such transition, spurred by the collaborative efforts in genomics and molecular biology. Crucial to the transition within biomedicine are data standards that can support interoperable data interchange about patients, disease, manifestations, genomic findings, and risk factors. This presentation will overview this principle, illustrate some progress in standards, and point to large-scale collaborations in the ontology development as examples.

Social Network Analysis- Evaluation Translational Collaboration: Social Network Analysis (SNA) is a particularly suitable tool for understanding the evolution of translational science at the level of the investigator and institution. SNA is being used to describe the social context and patterns of relationships between actors and is a useful tool for visualizing those relationships. Examples of how social network analysis is being used in CTSA and elsewhere are described. Results are in the form of both numerical data and a visual image called a sociogram or network map. This presentation will provide examples of SNA that include research collaboration networks of investigators receiving pilot project research awards, affiliation and interest networks to identify potential opportunities for multi-disciplinary interactions; informatics tools to mine existing data; expertise networks or "matchmaking" investigators with mutual or complementary knowledge or skill sets; co-authorships (publications, presentations, grants) and how clusters of co-authors emerge and change over time; mentoring relationships.

Can Older Adults "Make Sense" Out of Internet Health Information?
The Internet is emerging as a vital knowledge resource for consumers who need health information. In 2006, 113 million adults searched online for information on topics related to specific diseases, medical treatments and health insurance. One concern relates to the ability of people who are not "medical specialists" to find and comprehend information that is available online. This concern is particularity relevant to older adults as they are likely to be in need of and seek medical care. This paper will present findings from a study examining the ability of older adults to find and interpret Internet-based health information. Data regarding the relationship between health literacy and performance and perceptions of usability will also be presented.

An Open Source Approach to Health Care IT; Disruptive technology in action
In The Innovator’s Dilemma, Clayton Christensen reviews the significant differences between large companies that continue to rely on sustaining technologies that enhance current trends in an industry continue revenue generation and small companies that create disruptive technologies that herald the future. While he has cogent advice for large firms that, through technology watch groups, monitor and occasionally create disruptive technologies, he expresses more confidence in the finding that small companies will continue to provide the kernels for disruptive technologies. In the monograph “Open Source Software: a Primer for Health Care Leaders”, Goulde and Brown say that “The (health care IT) industry must rethink the way it develops patient-information software to reduce costs and increase flexibility, examine the way it distributes software to providers, and look at ways to add value to commonly used software rather than producing competing, functionally equivalent applications.” Goulde and Brown go on to say that health care IT is beginning to adopt the disruptive technology of open source software to address the challenges of: sharing patient information beyond the walls of individual institutions creating regional health information networks that allow duly authorized providers to securely and easily exchange clinical information expanding the use of electronic health records Tolven is an organization dedicated to the creation of disruptive, open source technology for health care information systems. Our company is one of the first open source organizations to focus solely on the delivery of healthcare and life science information technology solutions. Currently, Tolven has created an open source, standards based interoperability platform for health care, as well as patient/consumer and clinician solutions (i.e., an EHR configured for practicing clinicians – the eCHR - and a “companion” EHR configured for patients – the ePHR). The solutions created by Tolven are designed to support collaboration among patients/consumers, physicians and other care providers.

Cognition and Biomedical Informatics: Relationship between Knowing, Thinking, and Doing
Technological development often outstrips its productive use in a community of practitioners. Enhanced functionality and efficiency afforded by new machinery needs to be balanced with concerns for usability, learnability, and adaptability to the needs of the setting. As information becomes more readily accessible in the near future, will the need to engage in effortful learning be diminished? If answers to questions can be obtained much more easily through new information resources, will it be as important to have knowledge in one's head? Research in cognitive science at the interface of Biomedical Informatics addresses some of these lurking questions.

An Ontological Approach to BioSense Message Analysis for National Syndromic Surveillance
The CDC has embarked on a massive effort to centralize a feed of anonymized HL7 messages for the purpose of enhancing surveillance for agents of bioterrorism and for syndromic surveillance of routine public health pathogens. This leads to new challenges for processing the millions of messages received each day to glean clinical, laboratory, pharmacy and radiology findings of interest and pertinence, and route these to the appropriate analyst for further evaluation in a timely way. I will present an ontological, services based method that allows direct message processing, classification, runtime analysis and visualization of extracted knowledge that can aid the human analyst to meet the mission of timely and accurate evaluation of messages to promote situational awareness.

OMICS -Genomic, Proteomic, Metabolomic Data in Tomorrow's Health Care: Information-Driven Decision-Making and Personalized Medicine
In the next 10 years, the availability of patient genotype information will transform health care. The cost of a whole genome scan is expected to drop below a thousand dollars per person. Practically all persons in the industrialized world will be genotyped. This will open the door for a more refined approach to estimate the individual’s risk to a disease or the predicted response to therapeutic choices. Multigenic, complex diseases, e.g., type II diabetes mellitus, hypertension, obesity will be managed using patient-specific information rather than one-fits-all diagnostics and trial-and-error-based therapeutic decision algorithms. Pharmacogenomics will become a reality. In addition to genotype information, the use of gene expression, proteomic, metabolomic, and epigenetic profiles will add to the complexity of healthcare. Current OMICS technologies, the data they generate, and the methods used for data analysis will be discussed.

"Breakthrough" Informatics: Prospects for a Paradigm Shift in Biomedicine 
The presentation will begin by suggesting a "fundamental theorem" that unifies the field of informatics across biological research, clinical research, health care, and education. The fundamental theorem directs us to think about informatics as a field in pursuit of making people better at what they do, by forming synergistic partnerships between persons and information technology. The value of the fundamental theorem, to clarify thinking about this rapidly evolving and easily misunderstood field, will be illustrated with several examples. The notion of the fundamental theorem will then be extended. I will define "incremental" informatics--which includes much of the progress in informatics to date--as work that seeks to enhance practice-as-usual in a field, without altering in significant ways how work is done. In incremental informatics, it usually is not clear whether the person-technology partnership is making matters better or worse. I will then introduce a new concept of "breakthrough" informatics where the person-technology partnership engenders revolutionary change in how work is done, largely by making possible things that were not possible before, and where it is often visible to the naked eye that the effect of the partnership is transforming or paradigm shifting. I will contrast examples of incremental and breakthrough informatics as they apply to basic and clinical research, health care, and the education of health professionals. I will recommend that, in these times of scarce resources, we set our sights exclusively on informatics with breakthrough potential.

Machine Learning methods for the detection of schizophrenic language behavior
Artificial intelligence techniques and in particular machine learning are applied to a text classification task to determine mental health problems. Inputs are transcribed speech samples from a “structured-narrative task” and outputs are psychiatric categories such as schizophrenia. In a preliminary trial, subjects from three groups generated speech samples: those with clinically diagnosed schizophrenia (31 patients), clinically diagnosed mania (16 patients) and controls (9 subjects). Even though the structured narrative task resulted in the use of a limited vocabulary by all subjects (only a total of 1100 different words were used), a classification performance approaching 80% accuracy was achieved for the schizophrenia vs. control task. Classification results at this level indicate that the method is suitable for diagnostic or screening purposes. It is expected that results improve further in experiments utilizing free-speech samples.

CA-EDRS: Building and Deploying a Mission Critical System for California 
California currently processes over 250,000 new death certificates per year (1 in 10 deaths in the U.S.). CA-EDRS is California’s system for electronic death certificate registration and provides the ability for coroners, funeral directors, doctors, and hospitals to submit electronic death certificates for registration 24 hours a day. The CA-EDRS system was built by UC Davis and deployed on January 1st 2005. CA-EDRS system development required the use of software engineering and informatics strategies that allowed rapid iteration without compromising quality. The challenges and ‘lessons learned’ in the development of the CA-EDRS system are described. Concepts and principles relevant to the development of large-scale, mission-critical public health informatics software systems are also presented.

Distributed Immersive Virtual Reality Simulation for Education, Training and Performance Assessment 
Simulations are being used in education and training to enhance understanding, improve performance, and assess competence. Validated virtual reality (VR) simulations provide a means of making experiential learning reproducible and reusable. Advanced communication networks, such as Internet2 Access Grid, allow dissemination of these simulations and collaborative learning independent of distance. Our ongoing experiences led to an inter-institutional, interdisciplinary collaboration to further develop and evaluate an integrated, fully immersive, interactive VR system designed for medical education and training. This environment employs simulations that are visually three dimensional and are driven dynamically by a rules-based artificial intelligence engine within FLATLAND ™ (a virtual environments development software tool) and associated commodity hardware. These efforts have, in turn, led to iterations of the system to improve practical applications to meet specific user requirements; cutting across the integration of computing, networking, human-computer interfaces, learning, and knowledge acquisition. VR simulation creates a safe environment to make mistakes and could allow rapid deployment for just-in-time training, education on demand, or performance assessment. *Co-authors: Thomas P.

Managing Scientific Data: From Data Integration to Scientific Workflow
Many scientific disciplines and computational sciences require effective and efficient ways to manage scientific data. An obvious technical challenge in several of these disciplines is the massive volume of data (sometimes now reaching Terabyte and Petabyte proportions). A maybe less obvious challenge lies in the (semantic) complexity and heterogeneous nature of scientific data. In this talk, I will give an overview of the challenges and approaches towards a solution for managing and integrating complex, heterogeneous scientific data. In a nutshell, ontologies and logic-based knowledge representation techniques can help in capturing scientific vocabulary and "domain knowledge", thereby facilitating data integration. Furthermore, tasks such as data access, integration, analysis, and visualization can be "glued" together by capturing them as individual processes of a larger scientific workflow. In this way, scientific workflows facilitate the (semi-)automation and reproducibility of scientific data management, analysis, and knowledge discovery. Examples from bioinformatics, ecoinformatics, and geoinformatics, motivated by various ongoing projects, are used to illustrate scientific data integration and workflow issues and techniques.

Artificial Intelligence in Public Health Applications
Public health surveillance has typically been done with pen and paper but the CDC Public Health Information Network has started to transform the national public health surveillance infrastructure to an electronic based set of systems. Many of these systems have simply transformed the paper form to a screen representation with little else to distinguish the computer method of data collection from the paper based method. This lecture will entail an overview of how California is departing from this paradigm by using a highly structured and flexible knowledge source with built in rules in combination with a backward and forward chaining rule engine to drive it's statewide morbidity reporting application. We will discuss the advantages of abstraction of vocabulary and rules from the application and discuss issues of maintenance and authoring of an ontological knowledge model.

Biocomputation: New Paradigms & Technologies
As Systems Biology becomes more and more of a unifying force in the arenas of Genomics, Proteomics, Metabolomics, Nutrigenomics, and the other ‘omics’ sciences, most currently existing biocomputational platforms will be overwhelmed by the informatic tasks soon to be demanded by researchers. Within the next several years, we predict that increasing numbers of experiments will produce databases consisting of hundreds to thousands of measurements on tens of thousands to hundreds of thousands of entities such as genes, proteins and small molecules. For example, a nutrigenomics crossover intervention study could easily involve 200 subjects, each sampled 100 to 200 times over six months – with each sample analyzed for genomic and proteomic expression and metabolomic profiling of over 200,000 entities, producing about eight billion individual measurements for the entire experiment. Significant improvements in computational infrastructures will be needed to analyze, visualize, and discover new knowledge about these entities and their complex interactions in living organisms. These computational challenges will rival those found today in nuclear weapons simulations, climate modeling , weather prediction, astrophysics, and hydrodynamics. In this presentation, I will discuss the nature of the hardware and software components of biocomputational infrastructures that will enable researchers to achieve these goals.

Building Ontologies from the Ground Up
Building ontologies that capture the concepts and relationships in different areas of human activity no longer is exclusively the province of philosophers or even that of computer scientists. Professionals of all kinds increasingly recognize the importance of creating explicit, formal models of the activities and objects with which they deal in their work and of the data that drive their decision making. Nowhere has the development of ontologies become more important than in biomedicine, where there are burgeoning grassroots efforts to codify human knowledge fur purposes of document retrieval, data analysis, and decision support. These pragmatic efforts, such as the initiative to develop the Gene Ontology, are enormously important. They do not always adhere to standard conventions for domain modeling or knowledge representation, however. There are obvious growing pains as workers most concerned about content knowledge learn to formalize that knowledge in a way that can facilitate automated information management and decision making. Professional societies, government agencies, and educational institutions can be enormously beneficial in providing resources to bolster these activities and to ensure that resulting ontologies are sound and maximally reusable. The advent of "the information society" requires the codification and dissemination of human knowledge in electronic form. Particularly in biomedicine, the people who work closest to that knowledge are already taking major strides to build the necessary ontologies and knowledge resources.
