  • Disruptive Technology Assessment Game 'DTAG' Handbook V0.1
    Disruptive Technology Assessment Game ‘DTAG’ Handbook V0.1 Executive Summary What is the DTAG? The Disruptive Technology Assessment Game (DTAG) is a table-top seminar wargame, used to assess potential future technologies and their impact on military operations and operating environment. How is it played? There are four distinct steps in executing a DTAG experiment. The first two are part of the planning process, prior to playing the game. Step 1: Identify Possible Future Technologies that are under development and are of interest to the military. Step 2 – Create Ideas of Systems (IoS) cards from the technologies identified. Specific technologies, or combinations of technologies are combined with equipment to create new systems that could be employed by the military or by an adversary. These are described on cards. Step 3 – Play the DTAG. Figure 1 summarizes the process. Red teams and Blue teams both plan courses of action in the context of a scenario & vignette. After the initial confrontation of plans, which establishes the baseline, the teams plan again with the addition of future technology from the IoS cards. The second confrontation highlights the effect that the technology has on the plans and the wargame outcome. Figure 1: The DTAG Process Step 4 – Assess the results of the wargame through questions and analysis of data captured. Who plays it? The DTAG unites Technology experts, Military and Analysts providing a broad perspective on the potential impacts of future technology on military operations. The approach allows for an element of unconstrained thinking and the wargame-like rounds encourage open communication opportunities. Why should a DTAG be played, and when? It is most useful when assessing technology that is a prototype or at early stage of development, or technology that is not in widespread use by the military.

  • Strengthening Care Management with Health Information Technology a Learning Guide
    Strengthening Care Management with Health Information Technology A Learning Guide Presenting lessons learned by the 17 Beacon Community Awardees of the Office of the National Coordinator for Health Information Technology in the U.S. Department of Health and Human Services July 2013 i The Beacon Community Cooperative Agreement Program demonstrates how health IT investments and Meaningful Use of electronic health records (EHR) advance the vision of patient-centered care, while achieving the three-part aim of better health, better care at lower cost. The Department of Health and Human Services, Office of the National Coordinator for Health IT (ONC) is providing $250 million over three years to 17 selected communities throughout the United States that have already made inroads in the development of secure, private, and accurate systems of EHR adoption and health information exchange. Each of the 17 communities—with its unique population and regional context—is actively pursuing the following areas of focus: • Building and strengthening the health IT infrastructure and exchange capabilities within communities, positioning each community to pursue a new level of sustainable health care quality and efficiency over the coming years; • Translating investments in health IT to measureable improvements in cost, quality and population health; and • Developing innovative approaches to performance measurement, technology and care delivery to accelerate evidence generation for new approaches. For more information about the Beacon Community Program visit www.healthit.gov. This Learning Guide is part of the Beacon Nation project and is funded by the Hawai’i Island Beacon Community, an awardee of ONC Beacon Community Program. The Learning Guide was produced by Booz Allen Hamilton, under a contract with the Hawai’i Island Beacon Community.

  • How to Leverage Health Technology to Improve Patient Flow
    How to Leverage Health Technology to Improve Patient Flow 3/31/2017 A growing population has led to an increased demand for healthcare services. Concurrently, healthcare reforms and reimbursement requirements necessitate improvements in quality care and patient satisfaction. Healthcare facilities have begun searching for ways in which to handle the influx of patients without sacrificing either quality or the patient experience. How can your facility achieve increased volume and profits while maintaining quality and improving patient satisfaction? This whitepaper addresses how RTLS (Real Time Locating System) technology can be implemented to solve critical issues such as: · Increased capacity · Decreased waiting times · Patient and staff satisfaction · Increased healthcare staff productivity Increased Capacity The aging population in the United States is requiring more healthcare services. As the Baby Boomer population ages, almost twenty percent of the current population living in the United States will reach age 65 or older. This increase in the aging population leads to a significant growth in the number of individuals with chronic conditions. According to the American Hospital Association, the number of Boomers with multiple chronic conditions is continuing to grow and will reach about 37 million adults by 2030.i The prevalence of chronic conditions is also increasing in the United States population as a whole and calls for increased medical services and innovative approaches on how to properly deliver care to this population. Many healthcare delivery systems are utilizing RTLS technology to meet the increased population challenge. The Nor-Lea Medical Clinic in Lovington, New Mexico implemented an RTLS system to handle their growing influx of patients.

  • Horizon Scanning for New and Emerging Technologies in Healthtech What Do the Present and Future Hold? Foreword
    www.pwc.com/sg Horizon Scanning for New and Emerging Technologies in HealthTech What do the present and future hold? Foreword A collaborative, data-driven and evidence based study The last few years have seen an explosion of technology along with an increasing convergence of the Healthcare, Medical Devices, HealthTech, Pharma and Digital realms. It is imperative that in the midst of this, we keep the patients and their problems at the heart of it all. To effectively do so, understanding continuously evolving patient needs will be critical. And by doing so, we can better solve the real challenges they face and provide solutions to complement current clinical practices and technologies to improve what we at PwC call the 3 As in healthcare: Affordable, Accessible and A+ quality care. However, with the rapid and exponential pace of technological advancement, how do we keep track of the game-changing and clinically impactful developments? What are the present trends driving these developments, and what are likely future trends? Is there a fit-for- purpose framework that can be applied to assist in the assessment of these technologies? What will be the implications to regulators, health technology assessments (HTA), policy makers, payers, healthcare professionals and any and all other stakeholders? Horizon Scanning for New and Emerging Technologies in HealthTech aims to answer these questions. For the purposes of this paper, MedTech refers to the traditional innovation-led, fully integrated medical device industry. HealthTech on the other hand, refers to information technology (IT)-led solutions which are more patient-focused and comprise start-ups and non-traditional players who are causing an industry paradigm shift.
