Define: a.

Regional Health Information Organizations (RHIOs) b.

c.

d.

Health Information Exchange & Interoperability (HIEI) National Health Information Network (NHIN) The “Federated” model for technology deployment Identify several, strategic, Internet-derived technologies that are being successfully deployed to exchange community-wide health information Understand the benefits of these technologies for RHIOs 3

RHIOs

Public and Private collaboratives that:

enable health information exchange in a “region”

are bigger and fewer than Local Health Information Infrastructures (LHIIs)

serve approximately 500,000 – 1,000,000 lives

service area concept, such as Emergency Medical Services (EMS)

are no larger than a state (OR, WY, IL, DE)

4

HIEI

Health Information Exchange –

Interconnecting care

Interoperability (per HL7; per the IEEE Standard Computer Dictionary) –

The ability of two or more systems or components to exchange information and to use the information that been exchanged

5

NHIN

Tying together all the RHIOs

  

an interconnected, interoperable, electronic health information infrastructure/network with the capacity to electronically exchange the information between and among all the electronic health records (EHRs) so that a complete, electronic health record can be assembled whenever and wherever a patient presents for care

The “ Medical Internet ”

6

The “Federated” Model

The 5 Ds – Distinct, Distributed, Disparate, Decentralized Databases

The only Centralization occurs with an Enterprise-type Master Patient Index (EMPI) and, perhaps, Application Programming Interfaces (APIs)

Mirrors the “federal/federated” concept of the 50 state govs (Decentralization) reporting to the US gov (Centralization)

7

Internet-derived Technologies

Peer-to-Peer Networking

Secure Messaging

Virtual Private Network

Web Portal

Web Services

8

Peer-to-Peer Networking

A communications environment that allows all addressable devices (e.g., desktop and laptop computers) in the network to act as servers and securely share their files (any type of digital file – audio, coded, image, text, video) with all other authenticated and authorized users on the network.

This works by providing indexes to the files.

Peer-to-Peer Networking

DESTINATION Only whole files are sent SOURCE Text Central Index Video Sound Lab Values Images

10

Secure Messaging

A communications environment that allows all addressable devices (e.g., desktop and laptop computers) in the network to act as clients to a centralized server that securely stores and forwards files digital file – audio, coded, image, text, video).

(any type of

This allows authenticated and authorized users on the network to retrieve those files (online pull / offline push) when required.

11

Path Info System

Secure Messaging

@ the End User’s Computer (e.g., the Physician’s Office)

HL7 Messages Lab Info System Transcription System

Interface Engine (if none, then Point-to-Point Interfaces)

Path Results Lab Results Med Rec Reports Rad Results ADT

Connection Engine

Rad Info System Data Transferred via TCP/IP Sockets

Connection Server For Storing

Healthcare Info System

@ the Hospital / Reference Lab / Payor Data Center

Internet Encrypted Internet Encrypted

Server For Storing & Forwarding

Replication

@ the Hosting Data Center

12

Virtual Private Network

A private network that is configured within a public network, such as the Internet, providing encrypted point-to-point links (using SSL or IPsec).

This ensures that only authorized users can access the network and that the data cannot be intercepted.

13

Virtual Private Network

Reference Lab Community Network Hub

Cisco 3015 VPN Access Concentrator Cisco 3040 Router

Internet

Cisco 2600 Router with VPN SW Broadband required

POP Site-to-Site VPN – Hub & Spoke

Lower cost, tunneled connections with VPN services, like SSL or IPSec encryption and QoS to ensure reliable throughput Cisco 2600 Router With VPN SW Broadband required

Home Health Agency Physician Provider Remote Access VPN

Secure, scalable, encrypted tunnels across a public Network; client software required 14

Web Portal

A single point of personalized access (i.e., an entryway) through which to find, organize, and deliver content*.

*Content is defined as information, applications, and services.

Content can be:

structured, such as relational data.

unstructured, such as emails, web pages, images, and text documents. 15

PAYOR INFORMATION

Claims, Eligibility, Referrals

PHYSICIAN OFFICE INFORMATION

Insurance Plans& Demographics Prescriptions, Medications, H&Ps, & Progress Notes Procedure & Diagnostic Codes

DIAGNOSTIC TEST INFORMATION

Reference Lab Orders and Results Imaging Center Orders and Results

Web Portal

PHYSICIAN PROVIDER

Secured Single Sign On Custom Views & Workflow (Inbox, Alerts)

PORTAL PATIENT-CENTRIC INFORMATION REPOSITORY

Custom Views & Workflow (Inbox, Alerts) Secured Single Sign On

ACUTE & POST ACUTE CARE FACILITY PROVIDER EQUIPMENT & SUPPLY INFORMATION

Purchase Orders and Order Status Online Catalogs

ACUTE & POST ACUTE CARE FACILITY INFORMATION

H&Ps, Discharge Summaries, ADT Data Laboratory, Radiology, Pathology Results

OTHER INFORMATION: Continuing Education Clinical Databases

MEDLINE, PDR, National Disease Registries CNBC, ESPN, Amazon, Travelocity 16

Web Services

An open, standardized way of integrating disparate, web-based applications – using

• • • •

eXtensible Markup Language (XML) to format / tag the data Simple Object Access Protocol (SOAP) to transfer the data Universal Description, Discovery, and Integration (UDDI) to list what services are available Web Services Description Language (WSDL) to describe the services available

Internet-derived Technologies

BENEFITS FOR RHIOs

     

Are more “open” than proprietary Have a better chance of being widely implemented Reduce custom development time / costs Simplify user training / Promote physician usage Do not require centralized databases Take advantage of economies of scale and management of large networks
