5. • Malaria Control
• State Health Management Information
Systems- In seven States with Hospital
Information Systems.
• Routine Immunization Management Program
• Sporadic use in Medical College Hospitals
The first generation IT systems are characterized
by low expectations, effectiveness and
complexity..
The 1st
Generation
Systems
(1993–2005)

6. • The National Health Management
Information System- common Web- Portal
with entry-
States develop a large number of systems-
1.Human Resource Management Information System.
2.Hospital Information Systems
3.Disease Surveillance Systems
4.Drug Logistics and Inventory Systems
5.E- Tendering and Procurement Systems
6.Clinical Establishments Licensing and Regulation

National Rural
Health Mission
Catalyzed

7. Main Positives of the Second Phase
• IT is now seen as mandatory in all aspects of
health systems management.
• High degrees of complexity and sophistication in
systems.
• Rapidly accelerating expectations.
• For example : From 600 district reports (2008), to
5000 block block reports ( 2011) to 2 lakh facilities(
2012), to 6 crore mothers and children, below 2
!!!!!
• AND NOW to every health encounter ???

o Every program/ state develops own IT solutions. States have 10 to 30
systems
o No help to integrated decision making for Public Health management.
o State to central exchange very poor- and even at the same level.
o Systems a struggling with poor design and falling short of objectives.
o Private Providers not participating in information exchange.

9. Importance of Inter-operability
realized.
• In Public Systems:
– To reduce work load in data recording and
entry.
– To support decentralized , horizontally
integrated decision making.
– To improve quality and use of information.
– To allow rapid growth of new systems and
uses of IT.
• For Providers AND Patients
– to improve quality of care
– To enable continuity of care
• For Insurance Payers

13. MDDS Health Domain Standards
Building Blocks of MDDS Health Domain
o The health domain landscape are broadly
divided into 39 Entities.
o These entities are described and qualified
with the help of 1077 Data Elements.
o Values of Data Elements are categorized
under Data Elements (735), Values List
(201) & Code Directories (141)
o Meta Data are constructed to define each
Data Element and Code Directory to
establish Interoperability Standards
o Interoperability Standards
o Reference Architecture for Interoperability

18. Common Data Elements
• Defining Minimum Data Elements as standards is
difficult in Health Domain.
• Minimum Data needs of the Primary Care Setting would
be different from the Secondary and Tertiary Care
Settings.
• Health Domain has come-up with the Common Data
Elements which will act as superset from which program
specific data sets can be created.
• Data Set design is better left to the users.

systems through Identifiers
– Facility Identifiers (Unique Facility
Identification Number/Global
Unique Identifier)
– Provider Identifiers – Unique
Individual Health Care Provider
Number
– Patient Identifiers– UID/ Alternate
Unique Identification Number
– Disease Identifiers– ICD-10 Codes
– Service Identifiers– CCI Codes
– Document Identifiers– Document ID

23. Facility Identity Management

Suggested Model – Central Model

24. Further gains of this effort…
• Gone far beyond just clinical terminology standardization: Set
standards - administrative and operational parameters
• MDDS provides platform to dramatically accelerate use of
EHR standards/HL7/DICOM communication standards.
• Now in a position to be a global leader in healthcare IT useage
and implementations. Global Governments could also use
MDDS as a base and modify it for their local healthcare
industry .
• Allows greater democracy – in choose their own systems and
software applications, vendors and technical infrastructure :
within a ‘standards’ framework that ensure national
consistency in the reporting and management of healthcare
outcomes.

25. The Second Level of Interoperability:
Appropriate Integration Solutions will ensure Syntactic
Interoperability
Institutional
Interoperability
Syntactic
Interoperability
Semantic
Interoperability

26. Point-to-point Integration
 Pros
• Useful for all historical applications without much disruptive
changes.
• One eligible application can receive message from a source
application message channel.
 Cons
• Extra effort, time and cost to write Transformation logic for each
application.
• Semantic interoperability difficult to implement across different
applications.

27. Broker-Based Integration
 Pros
• Message broker can be
used to receive messages,
transform and route to
recipient application (Hub
and spoke architecture.)
• Data from finite set of
disparate applications can
be integrated using this.
 Cons
• Data discovery at run
time based on a service
request is difficult.
• May lead to a highly
complex architecture-
difficult to maintain.

28. Intelligent Gateway
(Health Information Exchange)
• Better suited to
current context.
• Based on Registry
architecture
pattern.
• Allows to
dynamically
locate the data
records and the
application
locations.
• Integration with
other domain
applications is
quite easy.

29. Choosing Integration Options
If within range of Tower in
Mumbai Circle, it has a registry
lookup to connect the 2
o Condition - II
o Broker
Integration
• Condition - I
• Point to Point
Integration
√ Condition - III
√ Exchange
Integration
• Any No. of Apps.
• Need to know where the book
is located in the Library. Else it
is like trying to find any book
without library catalogue
• Limited No. of Historical
apps.
• If Time & Effort not a
constraint
• Scalable to any number of
systems.
• Historical apps cant be retired.
• MDDS implementation with
deviations- Real world
• Intelligent broker is like -
Searching a book in electronic
catalogue – E.g. Amazon Books.

30. Third Level of Interoperability
Set of rules, guidelines on the way we collect and report
data- and of course the desire to dialogue and share:
Institutional
Interoperability
Syntactic
Interoperability
Semantic
Interoperability

31. Institutional Interoperability
 Guidelines, norms for data collection and
reporting, patterns of flow, aggregation and
context of usage.
 Different levels of digital capacity, different
granularities of reporting,
 Choice of standard, Indicators for data exchange.
 Most importantly a dialogue between
organizations, to understand information needs,
as well as barriers to better quality and use of
information.
 National Authority should be able to facilitate
this role.

32. Key Principles: Follow-up and Roll-out
1. Data standards are seen as dynamic- provision to be made
for constant upgradation and corrections.
2. Even the starting standards as released now, will need
clarifications, corrections, additions, deletions- standing
committee to help to this.
3. In private sector, the adoption would be voluntary- driven by
the advantages and ease of doing so.
4. In public sector it would be driven by financing
conditionality and needs for sharing information.
5. Once standards prove themselves, and ecosystems to test
and certify measure a mix of financial incentives and
disincentives for private sector could be considered.

33. Standards Roll-out and Adoption–The Steps
a. All centrally financed applications and software should
comply with these standards. This will be part of the
sanction of funds.
b. Specific proposals received to reengineer available public
health IT products to confirm to standards can be taken-up
on Case to case basis. Same would not be applicable to new
applications.
c. Adherence to standards- The MDDS committee may
consider accreditation and rate contracting suitable testing
agencies and only these may be allowed.
d. Creating Awareness- All major health IT symposia and
seminars to be covered to explain and popularise standards
so that industry voluntarily adopts the standards even solely
for private purposes.

34. Standards Roll-out contd..
e. Standards Updation- Suggestions, complaints, technical
snags should be conveyed to secretary of the MDDS
committee (mdds-mohfw@nic.in). (Reply to each of these
queries within a one month time standard).
f. Any modification would be notified on the website of
MoHFW, NHSRC and the main portal of the standards.
g. MoHFW would facilitate integration where requested.
h. Exchange between state financed and central financed
systems desirable- not mandatory.

37. Concluding Remark
• Solving the semantic barriers brings inter-
operability much closer, but there would be still
challenges to face.
• EHR standards and MDDS publication is thus
the first step of a long journey
….. not its final destination.
