Keynote: Integrating predictive analytics and telemedicine with the EHR
Time : 09:30-10:10
Biography:
Dan DuBravec is a senior consultant at LMI, a not-for-profit consulting firm headquartered in the Washington, D.C. area. Mr. DuBravec leads IT implementation projects and holds multiple EHR certifications, as well as a BS in product design from Illinois State University and an MS in educational technology leadership from George Washington University. His published articles on EHRs and Genomic data have been featured in the Journal of AHIMA (American Health Information Management Association). He is currently working with George Mason University on a research project focused on the Shareability and Accessibility to Big Genomic Data.
Abstract:
Healthcare providers are turning to predictive analytics technology and then integrating it with telemedicine to collect data from physician/patient video conferences, email and IoT monitoring for irregular vital signs. The aggregation and analysis of this data determines the best approach to improved clinical care. By predictively identifying patients at elevated risk, remote patient encounters will reduce repeated re-admission to hospitals and lower patient costs. The benefits are many, but Health IT administrators must be diligent in implementing and maintaining privacy standards and policies which protect patient health data. Policies, procedures, rules and roles must be part of an overall data governance strategy for telemedicine and patient analytics.
Massive amounts of clinical data are now being ingested into electronic health records (EHRs), ranging from ultrasound, X-ray, CT and MRI images, coupled with patient medical history, and most recently, genomic information. The centralization of patient information into health data lakes is creating vast amounts of unstructured information. This data will be used to create comprehensive predictive models and then pulled into EHRs, accelerating automated clinical support with life-saving interventions.
The most promising application of telemedicine and predictive analytics has been its impact on improving the quality of care in rural areas of the United States. Evidence suggests that the use of telemedicine results in a decreased need for in-person follow-up visits with medical providers. When physician specialists for personalized medical needs are required, and the patient lives in a rural area, telemedicine provides remote medical consultation within the comfort of the patient’s home. By allowing physicians to monitor their patients' health on an on going basis remotely, and then analyzing this data, illness is treated early on before it becomes life-threatening. In addition to the convenience and insights tele-predictive modeling creates, there is a reduction in the overall cost of care.

Abstract:
Assessment is an important factor for improvement on the part of the users and stakeholders of telemedicine programs. It provides feedback from which those involved can learn and make the necessary changes to enhance the operating environment. This presentation will discuss the following aspects of assessment with regard to telemedicine:
1) Computing methodology and software systems, including the valuation of the different technologies used today: pro and con, and the issues and problems that presently exist and how to improve upon them and
(2) Ethics, including the assessment of clinical practices, e.g. the delay in treatment, compromised databases, doctor-patient relationship, equity of access, and threats to privacy and
(3) Training of providers, including the design of courses.
With regard to the last subtopic, we will provide a somewhat innovative approach to assessment that will enhance the preparation of telemedicine providers for future success as creative and analytic providers of the future. The presentation will address the classification and goals of standard approaches to assessment, and a model of how to accomplish the aforementioned inventive approach, and its relation to mathematical concepts.

Howard University, USA
Title: Mobile access to clinical information at the point of care
Time : 11:30-12:00
Biography:
Fatima Barnes has worked as a technology integration specialist for more than ten years. She has also conducted research on the use of iPads and Tablets in clinical care while managing a medical library. In the past three years, the library trained more than 70 clinicians with teaching responsibilities on using or teaching with iPads and Tablets. Dr. Barnes has held preconference workshops on evaluated productivity tools for busy professionals and presented on emerging medical devices in health care. In addition, several abstracts and posters have been published and presented at conferences on the use of medical apps in professional education.
Abstract:
Objectives: Using library subscriptions and accessible on handheld devices, this study sought to promote authoritative health information apps, and evidence-based point-of-care resources.
Methods: Three cohorts of internal medicine residents were issued iPads at the beginning of their second year, and were trained to skilfully access resources from the digital library.
Pre- and post-intervention surveys were respectively administered at the beginning of the second year and end of the third year of training. The residents’ computer experience and computer knowledge was assessed. Additionally, before and after formal introduction to iPads, perceptions on the use of computers to access clinical information were assessed. Survey responses were compared using two sample methods and summarized through descriptive statistics.
Results: Sixty-eight residents completed the pre-survey questionnaires and 45 completed the post-surveys. There were significant improvements in the residents’ level of computer experience, and familiarity with medical apps. Furthermore, there was increased knowledge obtained in accessing clinical information through electronic medical records. Residents positively perceived the potential effects of computers and electronic medical records in medicine.
Conclusion: Study findings suggested that health science libraries can be instrumental in providing search skills to health professionals, especially residents in training. Participants showed appreciation of iPads and library support that facilitated successful completion of their related tasks. Replicating this study with a larger sample derived from multiple sites is recommended for future studies. Participation of mid-level healthcare professionals, such as Physician Assistants and Nurse Practitioners is suggested.

William Schoenl
Michigan State University, USA
Title: Microlending chickens and entrepreneurship: Empowering poor rural families in Kenya
Time : 12:00-12:30
Biography:
William Schoenl is Professor emeritus, Modern European History (including Imperialism) and Michigan State University. He is also interested in helping serve dire human needs overseas. He is cofounder of: the Chicken Project with Nutri-Fresh Farm & Agri-Hub in Thika, Kenya (2016-present); the Michigan State University Honors College Dire Needs Overseas Undergraduate Grants (2008-present, Endowment 2013-present); the Michigan State University College of Engineering Dire Needs Overseas Undergraduate Grants (2013-present); and the Canisius College Honors Scholarships for International Program (2008-present). His wife Linda Schoenl and he were Nyaka AIDS Orphans Foundation Volunteer of the Year, Uganda (2015). He has published five books and numerous articles. He was included in Who’s Who in America (2002-15) and Who’s Who in the World (2003-04).
Abstract:
This is about a project combining entrepreneurship and micro lending—two currently significant concepts in international development. The project’s purpose is to empower poor rural families with a source of income and protein-rich food through micro lending chicken start-up support. Its method is to partner with a non-governmental organization, Nutri-Fresh Farm & Agri-Hub, for creating agricultural entrepreneurs from subsistence farmers in Kenya. Each family is supplied with 50 chicks of the improved Kuroiler indigenous breed and signs a Poultry Project Loan Agreement. It states their obligation to repay—without interest—in the form of mature poultry cocks the costs of the chicks, feeds, vaccines, training and follow-up until the chicks attain maturity at six months. The repaid loan amounts are invested in new families. All families so far involved have eggs for sale and as a regular source of protein for themselves. They increase their asset through the additional hatching of their own chicks. They are repaying the loan. The project is now expanding to additional families in the Donyo region in Kenya. The repaid loan amounts allow it to continue sustainably in the future. Our conclusion is that this project combining entrepreneurship and microlending chickens has been successful and that it can be useful elsewhere and can include other agricultural inputs as well.

Jill Flo
University College of Southeast Norway, Norway
Title: Content validity of the modified OPCq instrument - A pilot study in home health care in Norway
Time : 12:30-13:00
Biography:
Jill Flo has her experience from clinical work as an Anaesthesia Nurse and from Department of Nursing Sciences as a senior lecture/associate professor. The research work is from evaluation studies concerning learning methods in nursing education using computer driven patient simulator in preclinical studies. She has evaluate use of learning management system and student’s evaluation of e-learning combined with traditional lectures, and suggestions for improvements in the post graduated program: Wound- prevention, treatments and palliation. She has also worked with project in interdisciplinary clinical practice (ICP). The research area is now the OPCq instrument a part of the RAFAELA patient classification system in home health care.
Abstract:
Statement of the Problem: A gradual increase in life expectancy has resulted in a larger aging population in developed countries. The number of hospital beds is decreasing and there is a shift towards nursing homes, residential care facilities and home health care (HHC). Due to the growing number of patients in HHC, a Patient Classification System (PCS) whereby the systematic registration of patients’ care needs, nursing intensity and the allocation of nursing staff can occur is needed. The validity and reliability of the modified OPCq instrument has been tested with good outcomes in hospital settings, and only once in primary health care for older people. In this study, the modified OPCq was tested for the first time in HHC in Norway. The purpose of this study was to test the content validity of the modified OPCq instrument in HHC.
Methods: A pilot study with a descriptive design. The data were collected through a questionnaire (n=44). Both qualitative and quantitative analyses were used.
Results: The modified OPCq fulfills the requirements for validity in HHC, but the manual may need some minor adjustments.
Conclusion: The modified OPCq seems to be useful for measuring nursing intensity in HHC. Staff training and guidance, high-quality technological solutions and that all technology works satisfactorily are important when implementing a new PCS. Further research is needed in regard to nursing intensity and the optimal allocation of nursing staff in an HHC setting.

Abstract:
Introduction: Giving presentation is an essential part in the medical practice. Physicians, in general are not expert in giving presentations, as it is not their daily practice. The weakness in conducting presentations comes from lack of the guidelines of making presentations and poor practice. Criticism is often directed to the facts emphasized in the presentations rather than the method of conduction. Therefore physician’s skills in making presentations have to be improved. The objective of this article is to provide the physicians or medical students with guidelines on how to prepare and deliver a structured and effective presentation in the medical practice.
Discussion: The structure of making effective presentation is based on 3 pillars (3Ps) Plan, Preparation and Performance (delivery of presentations). Plan starts with selecting an interesting topic for the audience, then to plot down the ideas and objectives with pen and paper. Sketch a script with logical flow of ideas and suggest related images or illustrations. Preparation of presentation passes through 3 steps:- Extensive reading, selective writing /typing before making interesting slides, the latter needs attractive foreground and comfortable background. Performance means the delivery process of the prepared presentation. The speech looks like telling a story, it should have a clear introduction, provocative engaging context and a logical conclusion. The needed skills and the difficulties of conducting speech, in addition to some important tips of giving presentation are fully explained in this article.
Conclusion: Presentation of teaching or research material has an important role in the work of health care professionals. The structure of medical presentation is based on three pillars: Plan, preparation and performance. Physicians should attain some skills in making effective presentation which are not sufficiently taught in the medical school.

Title: Health information exchange: Opportunities for improving lives of older adults in long term post-acute care
Time : 14:10-14:40
Biography:
Rebecca A Meehan is an Assistant Professor of Health Informatics at Kent State University, where she teaches health information systems, research, human factors and usability in health informatics. Dr. Meehan earned her doctorate in medical sociology and gerontology from Case Western Reserve University in Cleveland, Ohio. She has over 20 years of experience in applied gerontology, health research in technology, and software development. Dr. Meehan’s research focuses on usability of health IT (electronic health record) and the user experience of health information technology in long term care settings.
Abstract:
Statement of the problem: Communication technology, specifically, health information exchange (HIE) is creating opportunities for improving lives of older adults in long term post-acute care (LTPAC) settings. There is an increasing number of older adults worldwide. By 2050, the number of people aged 60 years and over is expected to increase from
605 million to 2 billion people, with the proportion of the world's population over 60 years of age to double from about 11 per cent to 22 per cent (WHO, 2014). Moreover, there are forecasts for substantial increases in the number of people with severe chronic conditions and/or disabilities in most parts of the world because of changes in fertility and life expectancy over the next fifty years. (WHO, 2002). Although many older adults will continue to live in their own homes or communities, some with formal or informal caregiving support, there is still a growing need for LTPAC services. In the United States, the number of people using LTPAC services is projected to increase from 15 million in 2000 to 27 million in 2050 (Harris-Kojetin, Sengupta, Park-Lee, & Valverde, 2013).
Methodology: A literature review was conducted to evaluate the state of HIE and its effects in LTPAC settings. Findings: Findings are summarized and presented to inform the current state and future potential of HIE in LTPAC, in the US and globally. It is critical to provide the right medical information to clinicians as older adults transition from a hospital (e.g. after a broken hip) to a LTPAC facility. Most commonly, a summary of care is sent from the hospital to the LTPAC facility, faxed or pinned to the gown of an incoming patient. HIE is an information technology alternative, and can streamline communication globally, allowing timely receipt and use of medical information, leading to improved care opportunities for older adults.

Jose Eduardo Corrente
University of Sao Paulo State, Brazil
Title: Use of asymmetric models to adjust the vitamin intake distribution data for older people
Time : 14:40-15:10
Biography:
Jose Eduardo Corrente has undergraduate in mathematics and took his MSc and PhD in Biostatistics. He is Associate Professor at Biostatistics Department -University of Sao Paulo State - UNESP, and his field of research is epidemiology of third age. Main projects are in quality of life, lifestyle and nutritional aspects for older people with respect to eating patterns and adequate intake as well as publications in reputed journals. Giovana Fumes has taken his PhD in Statistics and nowadays she is a Post-Doc researcher at “Luiz de Queiroz” Agricultural School working in asymmetric models for fitting nutrient intake distributions.
Abstract:
One of the main interests in the nutrition field is to estimate the distribution of usual nutrient intake. Data from vitamin intake generally present high asymmetry mainly to the presence of outliers. This can occur due to the variability of the diet and, in this case, robust estimation to get the distribution of the data can be required. Then, the aim of paper is to propose an alternative approach for estimating usual intake through asymmetric distributions with random effects applied to data set 10 vitamins obtained from a dietetic survey for 368 older people from Botucatu city, São Paulo, Brazil. In general, these asymmetric distributions include parameters related to mean, median, dispersion measures and such parameters provide good estimates for the intake distribution. In order to make some comparisons, a model fitted by National Cancer Institute (NCI) method with only for amount of nutrient intake was established using Akaike Information Criteria (AIC). NCI method is based on a Box-Cox transformation coupled with normal distribution but in case of asymmetric data, this transformation can be not useful. It was observed that, in the presence of outliers, the asymmetric models provided a better fit than the NCI method in the major of the cases. Then, these models can be an alternative method to estimate the distribution of nutrient intake mainly because a transformation for the data is no necessary and all the information can be obtained directly from the parameters.
