Commodity Internet vs. NGN • Current Internet • Passive, unintelligent • Best effort • Next Generation Network • Active, intelligent • Guaranteed effort • The difference: • “Quality of Service” - QoS
The notion of End-to-End “Quality of Service” - QoS Highly subjective application-dependent user-dependent Difficult to determine often obscured by smart applications programming often obscured by network architecture like caching
QoS Features for Healthcare Bandwidth reservation ( DCN ) Low latency Low jitter Variable priority • Data Integrity • Selectable loss rate • Security

The Problem: The US has enough health care resources and expertise but they are poorly distributed Some people have access to too much health care, some have access to too little Sparsely populated and economically depressed areas lack full spectrum of health care Generalists may be unwilling to practice in areas without specialty backup Aging population has increasing health care needs with increased access difficulty Increasingly ethnically diverse population
Some telemedicine facts… Almost 50 different medical subspecialties have successfully used telemedicine. There are approximately 200 active telemedicine networks in the United States, excluding radiology networks. About half of these active networks are providing patient care services on a daily basis.
Global Benefits of Telemedicine Potential reduction in health care costs Keeping patients local retains direct and indirect health care costs When patients leave the community for health care, their purchasing dollars go with them to the urban community
Healthcare and Next Generation Networking The U.S. National Library of Medicine is funding test-bed projects to demonstrate the use of Next Generation Networking (NGN) capabilities by the health community. These capabilities include: • Quality of Service • Security and medical data privacy • Nomadic computing • Network management • Infrastructure technology as a means for collaboration The demonstrations are designed to improve our understanding of the impact of NGN capabilities on the nation’s healthcare, health education, and health research systems in such areas as cost, quality, usability, efficacy and security.

Tele-Pathology Has great potential benefits Fewer providers need to view images Reimbursable Less common than radiology and more complicated Color is important Resolution required is much greater Images take much more storage space Most PACS systems are controlled by Radiology Departments

Lessons Learned - Overview Unanticipated social and economic barriers Cost “savings” is based on how cost accounting is applied Lack of equipment and communications standards Patient demand, as a market force, will drive adoption of telemedicine No business plan to support telemedicine after grant is completed Healthcare system must adapt to benefit from the immediacy and quick turn-around afforded by telemedicine
Lessons Learned - Patient’s view Acceptable to patient Satisfied with encounters, perception of better quality of healthcare encounter More personal responsibility for healthcare Ploy by health care system to prevent referral to specialist
Lessons Learned - Provider’s view Patient encounter were perceived as longer and more tedious but were actually shorter but more intense Early provider involvement yields better provider utilization Information sources made available to provider were under-used
Positive Trends Better off-the-shelf lower cost equipment Higher Internet bandwidth to the home High patient / family acceptance Applications that improve quality of care Integration of information systems within institutions and across health care institutions Wireless technology

FCC Rural Health Care Pilot Program - 2007 To facilitate the creation of a nationwide broadband network dedicated to health care, connecting public and private non-profit health care providers in rural and urban locations. $139M per year (Universal Service Fund) for 3 years to 69 projects in 42 states and 3 U.S. territories reaching over 6,000 health care centers. Provides direct payment to telcos for up to 85% of an applicant’s costs to: deploy (construct) and operate a dedicated broadband network connecting health care providers in rural and urban areas within a state or region; connect the state or regional health network to a dedicated nationwide backbone (I2, NLR). www.fcc.gov www.usac.org
FCC National Broadband Plan - 2010 • Create appropriate incentives for e-care utilization • Modernize regulation to enable health IT adoption • Unlock the value of data • Ensure sufficient connectivity for health care delivery locations www.broadband.gov
10.1: Create appropriate incentives for e-care utilization • HHS should identify e-care applications whose use could be immediately incented through outcomes-based reimbursement • When testing new payment models, HHS should explicitly include e-care applications and evaluate their impact on models • For nascent e-care applications, HHS should support further pilots and testing that review their suitability for reimbursement • As outcomes-based payment reform is developed, CMS should seek to proactively reimburse for e-care technologies under current payment models
Modernize regulation to enable health IT adoption • 10.2: Congress, states and the CMS should consider reducing regulatory barriers that inhibit adoption of health it solutions • Credentialing and privileging • State licensing requirements • E-prescribing • 10.3: The FCC and the FDA should clarify regulatory requirements and the approval process for converged communications and health care devices
