Values of Variables
• All computers that use a
relational database to process
data collect values of variables
from tables to form files
• Some of these variable values
will be known to you and
relatively stable, such as the
names and credentials of
providers, nurses, etc.
• Vendors ask that you capture
these values so they can be preloaded into the system master
files and tables – either by the
vendor or through you using a
wizard

Sources of Data Values
• Data values for system build may come from a variety of sources:
– A database or directory you maintain (data dictionary/metadata)
– Various forms you use (Form and Reports Inventories)
• Data values relative to payer rules, formularies, drug knowledge
are acquired by the vendor from their source (e.g., PBM) or a third
party (e.g., ICD, CPT), with any subscription fees passed to users
• Standard vocabularies recommended for use by the federal
government include:
–

Standard Vocabularies
• SNOMED (SNOMED International)
– Originally developed by College of American Pathologists and now distributed by
International Health Terminology Standards Development Organization, Denmark,
SNOMED is licensed for use in U.S. by National Library of Medicine. It is a
systematically organized computer processable collection of over 0.5 M medical
concepts and 1.5 M semantic relationships covering most areas of clinical
information such as diseases, findings, procedures, microorganisms, and
pharmaceuticals for consistent indexing, storage, retrieval, and aggregation of
clinical data across specialties and sites of care.
• LOINC (Logical Observations Identifiers Names and Codes)
– Developed and maintained by Regenstrief Institute, includes over 41,000 names
of laboratory terms, as well as nursing diagnosis, nursing interventions, outcomes
classification, and patient care data set. Each database record includes six fields
for the unique specification of each identified single test, observation, or
measurement:

Standard Vocabularies
•
RxNorm
– Provides standard names for clinical drugs (active ingredient + strength +
dose form) and for dose forms as administered to a patient. It provides links
from clinical drugs, both branded and generic, to their active ingredients,
drug components (active ingredient + strength), and related brand names.
NDCs (National Drug Codes) for specific drug products (where there are
often many NDC codes for a single product) are linked to that product in
RxNorm. RxNorm links its names to many of the drug vocabularies
commonly used in pharmacy management and drug interaction software,
including those of First Databank, Micromedex, MediSpan, Gold Standard
Alchemy, and Multum. By providing links between these vocabularies,
RxNorm can mediate messages between systems not using the same
software and vocabulary.
•
Universal Medical Device Naming System (UMDNS)
– A standard international nomenclature and computer coding system for
medical devices used in applications ranging from hospital inventory and
work-order controls to national agency medical device regulatory systems
and from e-commerce and procurement to medical device databases.
UMDNS is maintained by ECRI and contains nearly 7,500 unique medical
device concepts and definitions (preferred terms), along with an
additional 8,000 entry terms to facilitate classifying of biomedical
information

Metadata
• Data about data
– Describes structured, or
discrete, data element
properties
– Must be kept up-to-date
– Changes must be
documented (“change
control” or configuration
management)

Importance of Metadata
• External reporting:
– Common meaning?
– Common representation?
• All data required to “fire” a rule must be present for a
clinical decision support rule to work correctly
– Changing the definitions of the data or requirements for their entry
puts use of the rule at risk
– Changes to metadata may be admissible in a court of law if there is
a question as to spoliation of evidence
•
A data administrator is often responsible for
maintaining the integrity of a data dictionary;
a database administrator makes the physical
changes in the metadata registry
•
Clinicians should approve all changes to the
data dictionary, especially as they impact
clinical decision support
•
Degree of flexibility an organization has in
managing changes to metadata varies with product

Example of Need for Change
Control
• A data element may now be required to be entered
(e.g., dose for a drug prescribed), but someone asks
for it to be changed to optional (e.g., so dose would
not always have to be entered).
• The decision to make such a change should be a
thoughtful one, with an appreciation for its impact
– If dose is not recorded by the user, will the system
automatically record a default, or can the user expect a call
from the pharmacy?
– If something goes wrong in the future (e.g., a default dose
was not changed when necessary), will you be able to track
why and when the system change was made if necessary?
– If a future version of the software depends on this data
element to be required and will not work properly as a result,
will you be able to track that it was this change that is the
cause of the problem now?

Screen Layout
• Some vendors enable screen design changes. Consider making
such changes:
– Only when absolutely necessary
– For an entire group or organization
– Such changes are costly to make and maintain
• Consider size and resolution of display screen
– Not only will some screens not display well on smaller devices used for
mobile professionals,
– But mobile professionals may use a variety of devices
• Consider user familiarity with computers
– Data entry and retrieval must be intuitive
• Instructions must be clear, but not to obstruct power user
• Icons must be able to be quickly understood (without mouse-over delays)
within context
– Navigating multiple screens may result in even a power user getting
lost
• Balance reduction of complexity with need for information density
– Regenstrief Institute has found that once a person begins to use an
EHR, one denser screen is preferred to multiple screens

16
Screen Layout Strategies
• Size and resolution of monitor (tablets
vs. notebooks vs. desktops)
• User familiarity with computers
– Balance reduction of complexity
with need for information density
• Sequencing, nesting, spacing,
color, icons, navigation
• Alerting
– Active
– Passive
• Variable Selection
– Balance flexibility with standardization
• Data entry shortcuts
• Templates

Data Entry Shortcuts
STRUCTURED DATA ENTRY
• “Click” boxes
• Drop down
• Type ahead
------------------• “Smart text” or macros
• Default values
• Cut (copy) and paste
• Drag and drop
• Drawing tools
• Speech commands
• “Click” boxes:
– Check box = multiple options
may be selected
– Radio button = only one choice
can be selected

Alerting Strategies
• Sounds or messages to
pagers, phone
• “In-basket” functionality
• Color, sound, &/or symbols
and indicators
• Pop-up boxes (active alert)
• Appearance of message or
icon (passive alert)
• Context-sensitive templates

• Data conversion = permanently replacing data from
one application to another application, such as moving
the clinic’s patient schedule from a PMS to an EHR
• Interface = in comparison, an interface sends data
from one system to another system, where both
systems continue to operate on the data as applicable
• Master file and table build = also in comparison,
allows stable data to be pre-loaded into new system
• Chart conversion = Making (selected) content of
paper charts accessible/usable in EHR

21
Interface Build
• Start early
– Prior to contracting, identify all interfaces
– Determine if EHR vendor can write all interfaces
• Is a third party interface developer (system integrator)
needed?
• Interface issues:
– Uni-directional or bi-directional
– What data? (all or some)
– Will a portal do as well?
• Need is to view information, not data (e.g., results review)
• Need is to access and use (hospital) applications (e.g.,
enter orders into CPOE)

22
Interface vs. Portal
• Interface – data entered into one system is also
sent to another system
• Portal – entranceway to access applications
and perform work at another site to which you
are authorized

24
Legal Health Record
• Subset of all patient-specific data created or
accumulated by a healthcare provider that may be
released to third parties in response to legally
permissible requests
• Basis is Federal Rules of Evidence, where in the
business record is “that information kept in the course
of a regularly conducted business activity.”
• Rules of e-Discovery, however, do not preclude
metadata (including data dictionary definitions and
changes, as well as date/time stamps of user entries
and audit trails identifying what user accessed what
data) from being further requested via court order

25
Converting Data to Output for Legal Health
Record
• Will structured data
entry result in:
– Structured data output
for subsequent
processing?
– Print files intended to
represent legal health
record but are not
customary or
interoperable?
– Need to produce a
screen shot for
achieving the legal
health record?
– Reports representing
various needs, including
for auditors, legal health
record, subsequent use?
