User Interfaces –
Overview of Options
•
Email Client
– S/MIME Encryption is popularly supported
– Downloadable Plug-in for Direct
@
•
Web Portal (or Webmail)
– Web Portal can be set up by HISP or HIE
– Webmail with plugin for Direct
•
EHR
– Module that enables Direct messaging
– Message generated and sent by EHR without
intermediate steps
Individual communities are likely to include instances of all user interfaces,
depending on provider preferences and choices in the local market

•
Encryption at Client
– Client does encryption/decryption locally
– Capabilities built into the EHR
– Relies on HISP for routing
•
Encryption at HISPs
– HISP provides encryption/decryption
– HISP provides routing
– Client interacts through EHR, Email, or Portal
•
Direct and XDR (optional)
– Some HIEs use the IHE XDR profile for push
workflows
– This deployment model enables compatibility with
the Direct Project

Individual communities likely to employ all deployment models, depending on provider
preferences and local EHR choices. States need to enable HISPs regardless.

Deployment Models –
Pros and Cons
Encryption at Client
Pros
Cons
•
Can utilize 100% off-the-shelf e-mail clients
available today (20+ email clients support
S/MIME today)
•
Offers TLS as a point-to-point additional
protection - also commonly available today
•
No PHI is exposed to any HISP
•
’Sent' mail folder can be examined for
inappropriate exposure of PHI
•
Configuration requires that the client can
handle S/MIME and address book to store
certificates; e.g., EHR or Email client with
S/MIME/certificates enabled
•
Harder to automate inside an EHR/PHR
workflow, though can be mitigated
Encryption at HISPs
•
Client does not need to perform S/MIME
functions, so any e-mail client can be used
•
The HISP has access to all the content so
could provide value added services, such as
informing of Account Disclosures
•
The management of certificates and private
keys is offloaded to the HISP, minimizing the
burden on the client's implementation
•
TLS is mandated between Client and HISP to
assure confidentiality of information
transmitted
•
HISP has full access to PHI – requires policy
consideration; e.g., BAA with provider or HIE
•
HISP has full access to Private key, thus can
6
impersonate the user
Threat Models for these deployments (including “Direct to/from XDR”) available at: http://wiki.directproject.org/Threat+Models

RIQI Direct Demo
What problems do the RIQI
deployment models solve?
The RIQI pilot enables an innovative solution to two difficult problems that will face
healthcare providers and health information exchanges in the coming years:
How do providers
demonstrate
Meaningful Use of
health information
exchange (hie)?
How do you feasibly feed
data from hundreds of
heterogeneous practices
into state Health Information
Exchanges (HIE)?
Direct Project
The RIQI pilot is proving out solutions to
both of these use cases
9
Using Direct to feed a Health
Information Exchange
The “Aha!” Moment:
If it is inexpensive and easy to share data between two individual
doctors using Direct, then why not use it to solve the bigger challenge by
swapping out one of the doctors for the state’s HIE?
How it works
•
•
•
Why it’s such an
elegant solution
•
•
•
•
•
Use Direct Project messages to securely transport health information from EHRs to
the HIE
Package information in standard Continuity of Care Documents (CCDs) that
capture all aspects of a patient’s health record
Work with EHR platform vendors to implement very simple updates that work in the
background so that doctors can focus on patient care
Agnostic of what EHR a provider has, or what customizations exist
Standard data format – no matter what the workflow, the CCD will be the same
Providers will already have Direct accounts for doctor to doctor communication
No special or custom connections required – just the internet
Utilizes the emerging national standards – nothing “special” for Rhode Island

Two Deployment Models
Two distinct deployment models are being implemented: (A) direct provider-to-provider
communication that meets Stage 1 Meaningful Use for health information exchange, and (B)
transparent clinical updates from the EHR to the state HIE currentcare, both via Direct
Model A:
Manual, direct
provider-to-provider
message
Sending Provider
Model B:
Transparent updates
of currentcare by
provider EHRs

MedAllies Direct Pilot
Technical Track
MedAllies use of the Reference
Implementation
• Currently MedAllies uses an unmodified implementation of the Java
Reference Implementation. There is a C# version as well.
http://wiki.directproject.org/Reference+Implementation+Workgroup
• SMTP and XD* are both implemented and work in synergy (all three
deployment models)
• MedAllies has performed testing with several EHR and Hospital
system vendors across three primary Meaningful Use use cases.
• Modifications may be needed for Configuration Services only
• Java Reference Implementation available in binary and in source
code open source distributions.
– Web services implemented in Tomcat, Mail service adapters
implemented in Apache James.

Building the Story Board
Creating the Message
• Actor (Determined by the provider organization)
• Functionality (Determined by the EHR System)
– What is in the message
• (Determined by: vendor e.g. free text in the Message; provider
organization e.g. version and functionality implemented (CPOE),
and ancillary systems integrated)
• Screen shot(s)
• Dependencies
– Practice
• e.g. CPOE implementation , ancillary integration
– EHR Vendor
• E.g. Upgrade with the desired functionality
21
Finalizing and Launching the
Message
• Actor (Determined by the provider organization)
• Functionality (Determined by the EHR System)
– e.g. EHR prompts with system events (such as d/c
order)
• Screen shot(s)
• Dependencies
– Practice
– EHR Vendor
22
Finalizing/Signing the Message
• Actor (Determined by the provider organization)
• Functionality (Determined by the EHR System)
– e.g. Automated inclusion of a standard data set (patient
demographics, reconciled active medications, allergies,
active problem list, etc.); Clinician selection of a pertinent
variable data set (pertinent test and study results,
procedures, etc.)
• Screen shot(s)
• Timeline for dependencies
– Practice
– EHR Vendor
23
Selecting the Intended Recipient
• Actor (Determined by the provider organization)
• Functionality (Determined by the EHR System)
– e.g. Automated entry of PCP of record by
EHR system
• Screen shot(s)
• Timeline for dependencies
– Practice
– EHR Vendor
