By way of a short introduction, this was the outline I submitted for my capstone project at OHSU. As you might guess, starting my capstone means I'm in the home stretch. I'll be writing more about this over the next six months.

Capstone Project Charter for Keith W. Boone
Abstract
Newcomers to the use of health IT standards often ask the question “Where do I
start?”. It is often difficult to find
applicable standards from the various organizations who are often the sole
publishers of these documents. This
project will develop an online index supporting search and retrieval of the
standards. During the project, the index
will be populated with content from several standards organizations. The search capabilities will be piloted by
interested individuals. Data will be
collected about usage of the system, and the utility of it to end users.
Introduction and Background
One of the most common questions asked by people who are
trying to understand health IT standards is “Where do I start?” Each standards development organization (SDO)
has its own web site and is often the principle (and possibly the only)
publisher of its standards. Health IT
implementers may need to identify or access content from multiple standards
developers, either to compare the capabilities of each, or to implement a
system that users each possibly in different ways. Other health IT leaders have suggested that
there be a common way to access this information[1],
but none is yet available.
While the American National Standards Institute (ANSI) in
the US provides an index[2]
of all its approved standards and is an authorized source for standards from the
International Organization for Standards (ISO), many organizations developing
health IT standards are not members of ANSI, nor are all health IT standards
necessarily available through ISO.
Furthermore, both organizations publish standards for more than just
health IT systems, making it difficult to locate healthcare specifications by
themselves.
Health Level 7 (HL7) has developed several specifications
that can be applied to this effort. The
HL7 Templates Registry Business Requirements[3]
specification describes metadata, policies, navigational, security, search and
other capabilities for a registry of specifications using one or more of the
HL7 standards. They also published a
metadata specification based upon a review 20 different standards or specifications
from four different SDOs in support of unifying metadata across clinical
quality standards[4]. Both specifications are applicable, but have
not yet been implemented in a system that searches across specifications from
multiple SDOs.
The United States Health Information Knowledgebase (USHIK)[5]
provided by the Agency for Healthcare Research and Quality provides a standards
portal[6]
describing the data elements found in the ANSI Health Information Technology
Standards Panel (HITSP), American Standards Committee (ASC) X12, and National
Council on Prescription Drugs (NCPDP) standards. This portal enables search for data elements
available in a limited number of standards, but does not support searching for
the standards themselves.
Project Design and Scope
The purpose of this project is to pilot a source of entry
into the variety of different standards available to health IT implementers,
informaticists and educators who want to learn more about health IT standards. The concept is based loosely upon PubMed, a
singular source of information for information from medical journals, but is
applied to standards published by SDOs.
Rather than populating the information in the index manually, this
project proposes to use existing information resources via RSS and/or Atom
feeds provided by an authoritative source (e.g., the SDO itself). Metadata information will be captured from
this feed and indexed in a repository, allowing those interested in Health IT
standards to search for, and compare applicable standards for different use
cases.
Methods
The project will develop a metadata model for health IT
standards based upon existing work, create a database to support search of this
metadata, enable population of the database via commonly available Internet
subscription formats (RSS and Atom feeds), and develop and test a search
interface for accessing health IT standards.
The database will be populated with content from at least three
SDOs. Once populated, the pilot will be
publicized to members of these SDOs and other organizations with an interest in
learning more about health IT standards.
Data Collection
The site will be instrumented to capture usage statistics in
two ways. Google analytics will be used
to capture specific details about web site interactions (links clicked, search
paths used, et cetera). Some
individually identifiable data may be present in data captured via Google
Analytics results (network and location).
The site will also be instrumented to collect other data from users including
specific search requests, time on site, and feedback about the usefulness of
the site. Individually identifiable user
information will not be captured or stored from this instrumentation (e.g.,
user identity, computer or network characteristics, et cetera).
Success Criteria
Upon completion of this project, I expect to have shown the
capability to readily create an index of standards from multiple SDOs, the
utility of such a site to the health IT community, and to have gathered feedback
about how to improve searching of health IT standards. Hopefully such a standards index will find a
permanent home within the health IT standards community.
