S&I Framework Overview


Specific health interoperability initiatives

guide the design and development of a

fully integrated and connected health

information system.


An
S&I Initiative
focuses on a single challenge

with a set of value
-
creating goals and outcomes,

and the development of content, technical

specifications and reusable tools and services.


Call for Participation:
The overall success of the S&I Framework is
dependent upon volunteer experts from the healthcare industry and we
welcome any interested party to get involved in S&I Framework
Initiatives, participate in discussions and provide comments and
feedback by joining the Wiki:

Our Missions

»
Promote a sustainable ecosystem that drives increasing interoperability and standards adoption

»
Create a collaborative, coordinated, incremental standards process that is led by the industry in solving
real world problems

»
Leverage “government as a platform”


provide tools, coordination, and harmonization that will support
interested parties as they develop solutions to interoperability and standards adoption.

A Brief History of the Data Access
Framework (DAF)


BlueButton initiatives enabled patients to access to their own
data



DAF is a similar concept, except it is focused on enabling
providers to access their patient’s data both within and across
organizations



Current industry standards are not modular enough to
allow the different types of data access desired by
Providers


NwHIN targeted and distributed queries


Multiple ONC initiatives Query Health, Innovation projects
identified multiple data access challenges within and
across organizations


9

Data Access Framework

Problems to Solve


Data Portability


Patient moving from one provider to a new provider


Quality Improvement


A need for customized “small data analytics” for quality
improvement


NwHIN/Targeted Query


Remote “chart pulls”


Public Health


Common framework needed

10


DAF
will identify/create/modify standards to solve basic data
access issues faced by providers


within
their own organization and across organizations in a
modular and substitutable fashion
.


DAF is focused on enabling providers, their tools and
applications to access their patient’s data


Through new or modified
standards DAF will allow
providers
to use new and innovative applications


improve and fill gaps (such as medication tracking, long
term care needs) in patient care


What is DAF

11

DAF
-

Example Real World Scenarios


A provider wants to access
data about
a particular population within his/her
practice
using quality
measures


For example the provider wants to know all diabetic patients with HbA1c >
8% within their organization


A provider wants to access the complete medical history of a patient to improve
care and use new tools and applications to improve care


Tools include predictive modeling, comparison with existing data sets etc.


Enable applications such as Medication Adherence and Tracking to be
used by patients and care givers.


Enable social workers and other care givers to consume the patient
information and determine the next steps in providing care. These may
include determining what kind of long term care facility best suits the
patient based on their demographics, diagnosis, medications etc.


Build an Extraction capability (such as an API) from EMRs

stories (sample illustrated in table below)

DAF


Challenges
Cont’d


To support the various user
stories and access
mechanisms there is a need
to create a modular and
substitutable framework that
can be evolve with the
industry over time



Modular framework can be
best visualized as a stack
of standards with multiple
layers independent of each
other



Substitutable standards will
provide the ability to
replace standards for a
single layer and reuse
standards from the other
layers

Scope


The work of this initiative will be done in 2 phases:


Phase 1 is focused on Local Access via Intra Organization Query


Phase 2 is focused on Targeted Access via Inter Organization
Query


The
following capabilities are In
-
Scope:


Define the modular layers for Data Access Framework to support
identified business and functional requirements.


Identify the existing standards that can be used for each layer of
the Data Access Framework including guidance for substitutability
of standards for both Local Access and Targeted Access.


Define Implementation Guides leveraging existing standards
where necessary to structure queries and query results for
identified business and functional requirements.


Identify standardized APIs that allow applications to query data in
a consistent manner across EHRs
.


We will work with FACA and OPP to coordinate policy issues
