The Challenge
Worldwide today:
– 1 billion adults
overweight
– 860 million individuals
with chronic conditions
– 600 million individuals
age 60 or older
– 75-85% of healthcare
spending is on chronic
condition management

The Solution: Personal Connected Healthcare
There is increasing evidence to support the value of remote
monitoring for individuals with chronic conditions, including:
•
•
•
•
•
•
35-56% reduction in mortality;
47% reduction in risk of hospitalization;
6 days reduction in length of hospital admission and
65% reduction in office visits;
40-64% reduction in physician time for checks and
63% reduction in transport costs

WAN Code
The Continua WAN interface is the component of the
Continua end to end architecture that enables measurement
data to flow from an Application Hosting Device (AHD) to a
WAN device with the resources necessary to share this
information with a Personal Health Monitoring Report
(PHMR) enabled system such as an Electronic Medical
Record (EMR).
The CESL WAN interface is a JAVA based code library that
provides the WAN Observation Sender component of the
Continua WAN interface for a AHD. This code library
implements the following interoperability standards:

The Problem
• Integration of Patient Care Devices
– Value Proposition:
• Supports on going care at lower cost points by
allowing patient to be at home
– Issues blocking effectiveness
• Many different devices
• Getting useful data to the people who need it
Providing Continua Solutions for a Connected Health World
The Continua Solution
• Continua is an industry trade association that
– Profiles standards that enable devices to
represent and deliver medical observations in a
common way
– Addresses regulatory issues associated with the
use of the information
– Promotes the market adoption of the overall
ecosystem
• Focus – The technical Framework

Overview
Providing Continua Solutions for a Connected Health World
PAN/LAN Interface
(Personal Area Network/Local Area Network)
Providing Continua Solutions for a Connected Health World
Representing Device Information
• Core Technology is from ISO/IEEE 11073
– 11073 Nomenclature: Maps a medical
understanding of an observation to a number
(systolic blood pressure)
– 20601 Standard: Building blocks for representing
and communicating information
– 104XX Specializations: How to represent a
particular class of device
Providing Continua Solutions for a Connected Health World
Device Classes
• ISO/IEEE 11073-104XX work on going, already
covers many common devices including:
– Pulse oximeter
– Blood Pressure
– Weight Scale
– Glucose meter
– Medication Monitor
– Peak Flow
Providing Continua Solutions for a Connected Health World
One collection point
• 20601 (Optimized Exchange Protocol) specifies
how a common local aggregator collects this
information from different devices
– One hub (PC, cell phone, TV, or home Internet
gateway) can collect data from any device from
any manufacturer
– Bluetooth, USB, ZigBee

PAN/LAN Interface (1 of 2)
Continua PAN Server (IEEE 20601 Agent)
• Pan Server sits on the medical sensor component or
Personal Health Device (PHD)
– Implements common data representation
– (Can) store data while device is “off line”
– Sends data to PAN Client when communication is possible
Providing Continua Solutions for a Connected Health World
PAN/LAN Interface (2 of 2)
Continua PAN Client (IEEE 20601 Manager)
• Resides on a hub or aggregation point (called an
Application Hosting Device) such as a cell phone or
PC
– Must be in close proximity to the server
component
– Can store data locally or forward data
automatically using other parts of Continua
Ecosystem

LNI PAN Building Blocks
LNI Provides core PAN/LAN technology
• HealthLink PHD – The PAN Server component for
medical sensors
• HealthLink OXP – The PAN Client for aggregators
– mOXP - Java implementation of PAN Client targeted at
Android platforms
– HealthLink SDK for Android
– OXPLib – Continua Certified PC class solution for Windows
32 and 64 bit systems

WAN Interface
(Wide Area Network)
Providing Continua Solutions for a Connected Health World
WAN Interface
Purpose – Move the data from the local
environment elsewhere
•WAN Sender
– Collocated on the AHD in the home environment
– Converts IEEE 11073 representation to HL7 2.6 form
– Sends data using IHE PCD-01 transaction
•WAN Receiver
– Sits in the web services of a professional organization
– Collects data from the WAN Sender
– IHE PCD-01 transaction

HRN Interface
(Health Record Network)
Providing Continua Solutions for a Connected Health World
HRN Interface
Purpose – To move medical documents
between organizations
• HRN Sender - The end point of the Continua
ecosystem
– Can be located on local AHD, or in professional
office
– Data is now represented in a formal HL7 3.0 CDA
•Measurement is in a component call a Personal Health
Monitoring Record
Providing Continua Solutions for a Connected Health World
Key Points
• Continua technology provides a standard
based approach to collecting device data
– Common tools for representing data
– Many devices specializations defined
– Path out of high cost locked proprietary end to
end systems
– Can integrate technology into system in a
evolutionary manner
