the words in the term EHR – S reflects the
boarder focus on the health of the consumer
or patient and indicates that the EHR – S may
be used by all participants in the process of

Different departments exert different
influence towards the common goal of an
EHR for most Americans. Other agencies
provide leadership by offering monetary
incentives; finding research, development and
demonstration projects; and shaping
regulations and policy.

The IHS has long been pioneer in using
computer technology to capture clinical and

The government is also pursuing the
development of a public – private national

The HL7 EHR –s functional model contains a list

Direct care functions are familiar to clinicians.
Supportive functions involves secondary use of the

Functional Model is the Creation of a Profile.
In this section we discuss five fundamental
guidelines that can help increase the
dependability of healthcare systems.
The infrastructure level, features that are
transparent to software applications should
be implemented to detect faults are detected

become catastrophic. To handle exceptions in

Fundamental Principle of System architecture
is that an enterprise system architecture
should be developed from the bottom up so
that no critical component is dependent on a
component less trustworthy than itself. At the
bottom of the architecture are the physical
and logical networks that support the
enterprise and provide the “pipes“ that carry
data from system to system.
The system planning process should
anticipate business success and the
consequential need for larger networks more

integration. Such models can provide valuable
input into planning for scalability and future
Managing and keeping complex network and
integrated system available and responsive
requires meticulous overseers – individuals
who know that failures will occur and accept
that failures are most likely to occur when
they are least expected.

The NMDS influenced the work of the professional
nurses association. In 1991, the Americans Nurses
Association (ANA) recognized the NMDS as the
minimum data elements to be included in any data
set or patient record.
The NMDS servers as a key component of the
standards developed by the Nursing Information and
Data Set Evaluation Center (NIDSEC).
NIDSEC develops and disseminates standards
related to nomenclature, clinical associations, clinical
data repositories, and system characteristics/
decision support/contextual variable pertaining to
data sets in information system that supports the
documentation of nursing practice (NMDS).
The Early NMDS work in the United States
spurred the development of NMDS in
numerous other countries. A perusal of these
data set reveals a definite consensus on the
importance of the nursing care elements
across all countries which identified NMDS’s.
Several countries across most continents
beyond North America are exploring
development of NMDS systems.
It is clear that there is major work being
accomplished across the globe to ensure that
nursing essential data will be more
comprehensively available in the future.

Nursing informatics is the nursing specialty
that endeavors to make the collection, and
knowledge easier for the practitioner,
regardless of the domain and setting.
Informatics is a science that combines a
domain science, computer science,
information science, and cognitive science.
Healthcare informatics may be defined as
the integration of healthcare information.
Healthcare informatics address the study
of management of healthcare information.
Nursing informatics reflects this duality as
well, moving in and out of integration and
separation as situations and needs demand.
In 1985, Kathryn Hannah proposed a
definition that nursing informatics in the use
of informatics technologies in relation to any
nursing function and action of nurses.
Nursing sciences, computer science and
information, and knowledge to manage and
communicate data, information, and
knowledge in nursing practice.
In early 1992, the ANA established nursing
informatics as a destine specialty in nursing
with a distinct body of knowledge.
The scope of nursing informatics practice
includes activities such as developing and
evaluating applications, tools, processes, and
strategies that assist registered nurses in
managing data to support decision – making.

This desired change in skills involves the
