Master Patient Index list
Please forgive the level of explanation; this posting will reach people of
all levels of background in health informatics.
We are inviting inquiries from parties to be included on a list to receive
routine updates on a health care effort to resolve problems with connecting
a patient's records which may reside in different health systems.
Please understand that this invitation and description of our activities are
not official products of the workshop but a preliminary view of the
activities by the sender.
Explanation of the problems around patient indices:
Most hospitals maintain a list of patients and associated patient id
numbers. Hospitals may merge or change associations and patients may shift
their care to different sites -often with completely different different
filing systems and associated numbers. There are many vendors who provide
very excellent and secure patient record systems to facilitate patient
record management for single enterprises but there is no standard method for
interfacing between different systems to locate patient records which works
between all systems.
The HOST consortium (http://HOST.scra.org) and the Computer-based Patient
Record Institute (CPRI) are co-sponsoring an on-going work-group on this
problem, to define the problem, to look at current solutions and to suggest
specifications for a standard, public-domain solution. This product
specification will be freely available for commercial production. This
effort is aimed at improving the healthcare process by:
making the consensual connection of record fragments possible;
easing the integration of disparate parts of possible enterprises; and
making the transition to new organizations easier
This effort will not be to develop commercial products but will only support
the problem definition for the integration of commercial index products.
The workshop and subsequent specification will be concerned with describing
the structure of a product which would, beyond technical issues, validate
the right of any site to make a query, the type and credential of the person
making the query and the approval level of the patient-client as indicated
at both initiating and receiving organizations. The final specification
would be placed in the public domain
No patient data would be exchanged by the query, merely a binary response
about the presence of client-patient data -(if allowed by the rights of the
inquiry and the permissions of the client-patient).
This system is not intended to, nor will it, support:
a national patient index
any unapproved access to records
any unapproved release of any information or even of its presence
blanket 'trolling' of patient databases
We encourage the nomination of other parties who may be interested in
subscribing to this list.
The posted communications to the list are expected to be oriented to the

Submissions will be posted only if they pertain to the technical agenda -
this is not a discussion group for ideologic positions.

You should include your name and affiliation(if any) in the body of the
e-mail. We will not limit access but are interested in knowing that we
reach as many segments of the HC informatics community as possible.
