2Messaging Data Standards
3Messaging Data Standards
- We really have the first level standards in hand
for EHR and ERx. NCVHS has reviewed and
recommended. The standards deal with - Messaging
- Syntax
- Optionality
- Vocabulary
- HIPAA, Electronic Medical Records, Electronic
Prescribing
Optionality has been a necessary and practical
requirement for Standards. Optionality is also a
primary barrier to interoperable electronic
health records.
4Messaging Data Standards
- What Problems Are We Trying to Solve?
- Ad-hoc Access to Medical Summary and Recent
Clinical Data? - The Complete Transfer of a Clinical Record?
- Facilitate the Use of Multiple Computer Systems
that Together Automate Clinical and
Administrative Processes? - It is important to acknowledge that the majority
of our experience is on number 3. - Optionality has traditionally been important
because clinical and administrative processes are
unique - Hospital to hospital
- Nursing station to nursing station
- Physician to physician
Process Optionality Significantly Complicates
Standards
5Data Messaging Standards
- Any given message must support a given process
with a required set of data. - Not knowing the process that is being supported
is a barrier to interoperability just like not
knowing the set of data that the target computer
system needs or the vocabulary that a specific
data element needs to use.
- Messages to
- Move a Copy a Patients Record
- Inform an ancillary departments computer system
of an admission - Submit a claim for reimbursement
- Order a test on a patient
- etc.
- All in the context of the action
Process
Semantec Interoperability
Syntactic Interoperability
Data
6Data and Messaging Standards
- HL7 Version 3 is designed to take a structured
definition of data and process and produce a
standard message based on both the data required
and the process being supported into a standard
methodology giving semantic interoperability. - This is not easy and has taken the HL7 community
(US and 28 international affiliates) the better
part of 12 years to create. - Model based standards development is
state-of-the-art. - The supported message syntax is XML (and has been
now for at least the last four years). - HL7 Clinical Document Architecture R2 is now also
ready as a compliment to HL7 Version3 to move
electronic documents as well as messages. - All are based on the HL7 ANSI Standard Reference
Information Model (RIM).

8Data Messaging Standards
- For the most part, every HL7 version 2.x message
is unique. - Modes for moving data
- Most US hospitals use HL7 Version 2.x to push
data in real-time between internal computer
systems in response to an event created by a
process (sometimes called and unsolicited
update.) (e.g., an order message is sent from a
physician order entry system to the pathology
departments system after the physician has
completed and confirmed an order). - Few, if any, vendor clinical systems are capable
of responding to ad-hoc queries for clinical
data. Nevertheless, we are developing models for
EHR and ERx that rely on movement of data in
response to a query. - Processing queries against complex clinical
on-line data stores severely impacts on-line
systems performance. Any existing system will
require re-architecting and additional hardware.

11Data and Messaging Standards
- Whats Missing? What could Change?
- An understanding by all that the HL7 V2 messages
in use today inside of hospitals with its
data-only capabilities is not going to deliver
a Portable EHR across the continuum of care. - Implementation Guides that describe Process and
Data movement to support Defined EHR Events - Medical Summary Transfer
- Patient Referral and Transfer
- Vendor Buy-In and required support in delivery
not just promises or statements of support.
12Data and Messaging Standards
- Whats Happening?
- HL7 Electronic Health Record Special Interest
Group (EHR SIG) is moving as fast as it can - DHHS and NLM is moving on implementation guides
- but
- ANSI Standards Processes are consensus-driven,
deliberative and collaborative none of these
easily support the Presidents time line. - DHHS / ONCHIT involved leadership could minimize
some of the infighting that is now occurring
between vendors and standards organizations (but
only in the US Realm!) - The alignment of interests in the commercial
world slows down consensus driven processes.
13Vendors
14Vendors
- With few notable exceptions at primarily academic
institutions, all healthcare information
technology in this country is delivered by a
relatively small group of vendors. - Clinical IT development only started in earnest
after IT systems to support administrative
processes (i.e., billing, finance, payroll)
occurred first. - IT Technology to support clinical processes is
relatively new and, as the Office of the National
Coordinator of Health Care IT has pointed out in
July, not very well deployed where most
healthcare is delivered (i.e., primary care
physician offices, small group practices,
ambulatory care clinics). - With only a couple of exceptions, vendors of HCIT
in this country do not delivery clinical IT
solutions to both hospitals and primary care
physician offices. This is true in the US and in
other countries (e.g., UK) as well.
15Vendors
- Given all of the above, it is surprising to see
the amount of sometimes fierce competition that
exists among / between vendors. - Cost of sales is very high, sales cycles are very
long and vendors want to place as much of their
product as possible in any won customer. - A number of factors make it difficult or
impossible for the management of a provider
organization to replace a vendor that does not
deliver on their promises. - Promises are in place now in the industry for
products that have not been delivered that could
easily take longer than the remaining 8 years
left to deliver on the Presidents Vision. - Control of the Patients and the Physicians
Desktop (i.e., the web portal) has become a
recent point of skirmish. We have no agreements
(or even serious initiatives) resolving the
question How does a web portal deliver
information sourced from multiple vendor
solutions to a single unified view?
16Vendors
- What Needs to Happen?
- Leadership that sets out a clear roadmap to the
vendor community. - What products need to support
- When they need to support it
- Independent Organizational Leadership
- Standards groups such as HL7 have served as a
forum for solving detailed technical
problems(i.e., the how once the what and when
have been defined). - The vendors and the market in general will
eventually find their own way. However, the time
and monies required to do it this way are well
outside of our goals.
17Vendors
- Vendor organizations (including standards
organizations) are prone to misuse of process
and are better known for slowly moving to a
desired goal instead of direct and decisive
movement. - Imagine what would have happened if NASA had not
taken control of the moon landing program but
instead just funded efforts for private industry
to get us there would we still be waiting for a
moon landing? - EHRVA is a good idea by the major vendors that
work in this market. It is not, however, likely
to produce decisive leadership that will get us
all implementing portable Electronic Health
Records. - HL7 EHR SIG is already demonstrating the problems
of competitive pressure in a consensus driven
process. (One or more vendors are willing to take
the appeals process to the limit if it could
force inclusion of features that they believe
would give them a competitive advantage in an EHR
function profile definition).
18Vendors
- Suggestion We have a working model for sharing
patient information in Indianapolis. It was
largely funded over a long period of time by
public funds. What would it take to turn this
model into our model?
19Privacy
20Privacy
- No single issue will derail Portable Electronic
Health Records or Electronic Prescribing faster
than Privacy.
- The American Public is very sensitive to this
issue. - The speed and severity of Congress in rescinding
the HIPAA Person Identifier demonstrates how
quickly a statutory requirement can disappear. - By and large, the medical industry in this
country seems to take a different view on the
mechanics of privacy when compared to countries
like the United Kingdom.
21Privacy
- The good news is that HIPAA already defines the
rules around Privacy for us. - The bad news is that it is largely a covered
entity policy based and we do not have the
technology-based implementation of that policy to
rely on for EHR or ERx. - Some vendors have implemented mechanisms for
controlling access and dissemination of protected
health information (PHI). However, by and large,
I have not seen this technology implemented.
There is especially little if any interest in
enabling what appears as cumbersome technology in
individual or small physician group practice
offices. - This is very unfortunate because there needs to
be a reliable and industry-wide way to record and
distribute PHI policy to the whole marketnot
just as it applies to a particular institution. - In short, privacy policy is rooted inside of the
covered entity and we have no particular way
to - Communicate an agreement between patient and
covered entity to a third party (i.e., the
recipient of PHI). - Assume that the recipient can electronically
act on the privacy policy information.
22Privacy
- Privacy Requirements need to be part of the What
and When implementation guides and overall
strategy description of both EHR and ERx. - Technology-based privacy protection needs to
understand what we are doing with PHI and how it
is going to be used. - Are we pushing data or are we responding to an
external query for data? - If the query is a web screen requesting medical
summary information that will be displayed in an
ER, how can we protect a patients privacy while
at the same time responding quickly and not
encumber the ER physician? - In either case, how do we know the requestor? How
do we know that privacy policy of the source
entity can or will be respected by the requestor?
In short, how to we normalize privacy policy
across provider organizations while not
significantly adding to the physicians workload
or otherwise slowing the physician.
23Observations from International Projects
24International Projects
- Most are aware that similar efforts are underway
in countries outside the US to support portable
electronic health records. - Many have been working on these efforts a lot
longer than the US - Most are financially sponsored by their national
governments - All have a healthcare delivery and ownership
model that is different than the US (and in more
subtle ways different than each other too). - The differences in organization make financial
comparisons difficult. For example, projecting
the October, 2004 UKs NHS expected 10 year
expenditures for NPfIT (or NHS Care Record) onto
the US would deliver a US cost of 148 B.
However, since the US DHHS does not own the US
healthcare delivery system (as the UK DOH owns
the NHS) it is not at all clear how you would
apply the same monies in the US. - Nevertheless, there are some lessons that can be
taken away
25International Projects
- For the most part the major country governments
have settled on HL7. Furthermore, HL7 Version 3.0
and CDA seem to be the preferred vehicle for the
movement of clinical information. - All other countries have chosen some form of
hierarchical data organization at either the
country or province level (with the notable
exception of the plans in the Netherlands). - All have expected that vendor off-the-shelf
solutions will play a very large role in their
architectures. - Not withstanding 3, at least Canada (initially)
and the UK have elected to write contracts with
the vendors (many US based) that effectively
require major modifications or whole-sale
re-writes of their applications in order to meet
the technical requirements of the contracts.
26International Projects
- The UK specifically expects to map HL7 v2
messages that are now generated by systems inside
of hospital to HL7 v3 on the Spine to and from
the Spines central repository. - The UK has elected to put private industry
contractors on-the-hook as solution
providersbuffering the NHS from the vendors. - In all cases, the responsible government entity
(national or provincial) has become very
prescriptive of exact function and process that
IT systems must support in order to be part of
the program.
27Transition Adoption
28Transition and Adoption
- Transition
- It is important to recognize that there is a
small percentage but nevertheless sizeable
investment in IT in the healthcare industry
today. - While most primary care physicians have not
automated clinical records, all reference labs,
most or radiology, almost all retail pharmacy and
many departments in individual hospitals have
invested in and routinely depend on information
technology for patient clinical data. - It is not practical to move the entire country to
a new set of government set (or even industry
set) standards at one time. - A transition plan to phase in function and
technology over time needs to be created. - The transition plan needs to deliver incremental
benefits and, at the same time, strongly
encourage the acquisition of new technology that
moves us all forward at the same time to a stated
goal.
29Transition Adoption
- Adoption
- Clinical Healthcare IT systems frequently fail.
Failure is defined as the lack of use of the
system. In short, the intended uses (i.e.,
physicians) refuse to make use of the IT system
when it is finally implemented. - Sometimes failure is technically partial but
nevertheless devastating in overall outcome
(e.g., we did not go-live on computerized
physician order entry, but rather reverted to a
unit-clerk based orders communications
application). - Ultimately, physicians and other clinical
professionals (e.g., nurses, pharmacists, etc.)
must use both the end applications and the
proposed infrastructure if EHR and ERx are to be
successful. - There is a gap today in the technology and
planning vs. the general understanding by
physicians and the clinical professionals that
will use these services. The clinical community
needs to be more aware and more involved.
