What are the components of a comprehensive health information system

A critical step toward realizing the National Health Information Infrastructure will be the development and widespread adoption of network standards for health care data and software. A CDA is a critical step in the standardization of clinical reports and is essential to pave the way for widespread deployment of NLP systems.

Five technical factors are important in planning for the implementation of communication networks: However, natural language extraction is currently a difficult and knowledge-intensive task. Of prime importance are standards related to the clinical document architecture CDAmarkup language, and a comprehensive standardized clinical vocabulary.

Further, such broad repositories are essential to patient safety because the clinical context usually cuts across multiple data sources. In addition, data from the Healthy People Midcourse Review demonstrate that there are significant disparities in access to care by sex, age, race, ethnicity, education, and family income.

Such efforts are unlikely to be replicated on a larger scale until the major technical, organizational, and financial impediments to the development of the NHII are addressed. With the NHII, information systems will be able to provide the right information, at the right time, and to the right individuals, enabling safe care and supporting robust safety reporting systems for cases in which adverse events and near misses do occur.

Such databases associated with the priority areas identified by the IOM have the potential to provide a valuable source of evidence to support the attainment of national goals for quality improvement and patient safety. Knowledge representation is the foundation for the standardized data utilized in clinical decision support systems and other digital sources of evidence.

It encompasses an information network based on Internet protocols, common standards, timely knowledge transfer, and transparent government processes with the capability for information flows across three dimensions: As discussed later in this chapter, however, significant advances have been made in the use of natural language processing of narrative text for the detection and prevention of adverse events.

This capability has significant potential to impact safety and quality care and will be a major contributor to the functionality of the EHR. Of prime importance are standards related to the clinical document architecture CDAmarkup language, and a comprehensive standardized clinical vocabulary.

Another example is stents, which are widely used for treating coronary occlusions and now have chemical coatings to prevent re-stenosis. One component of a CPOE system is computerized decision support. Methods of acquiring data may also vary by domain. Current research integrates a number of methodologies from both engineering and cognitive science to evaluate and design systems from the perspective of terminology use e.

INPC not only allows for the secure storage and exchange of clinical information but also provides clinical decision support and public health surveillance and reporting.

Common standards will allow the systems to exchange data that can be integrated into patient records and support tools in a manner that retains data comparability. The Internet can be used as well for communication among all authorized members of the care team e.

For example, developers may assemble modules, each apparently dependable, but, when they are integrated, problems and weaknesses emerge.

For example, determining a drug—laboratory value interaction requires information from the pharmacy and the clinical laboratory. The event monitor uses clinical rules, the triggering event, and information present in the repository to generate alerts, reminders, and other messages of prime importance in preventing errors of both commission and omission.

Additional information on standards for user interfaces is provided in Chapter 4. The ability to utilize, process, analyze, and reuse information, whether for patient safety or clinical care purposes, depends directly on the ability to organize the information into meaningful domains with hierarchies of specificity.

Public- and private-sector support for research on the development of very small, low-power, biocompatible devices will be essential for improving health care delivery. At the same time, the number of bits of memory on a chip has increased by a factor of more than a million, and costs have decreased just as precipitously.

Specific issues that should be monitored over the next decade include: American Heart Association; Because the information collected combines both scientific knowledge from the medical literature and systemic reviews based on experiential knowledge from patient databases or validated clinical guidelines van Bemmel and Musen,modeling of cognitive deductive and inductive processes requires standards for such matters as logic, decision trees, rule-based reasoning, frames concepts and their defining attributesand semantic networks, as well as the capability to represent the data at multiple levels of granularity.

Standardized terminologies exist for the core phenomena of clinical practice: Standardized terminologies exist for the core phenomena of clinical practice: The Automation of the Clinical Practice ACP Project at Mayo Clinic in Jacksonville, Florida, undertaken inincludes computer-based patient records and mechanisms for automated charging and order more Actionable knowledge representation through the use of information systems holds promise for better connecting clinical research and patient care practices Balas and Boren, One of the most frequent causes of errors and failures to carry out planned treatments has been a lack of integration of orders and results.

However, unless the approach is coordinated, the impact of new technologies could improve health care for a few but increase costs for everyone else and move the overall system even farther away from providing patient-centered care.

Research and development in the following areas should be supported: The status of various types of health care data standards and the gaps that need to be addressed are described in detail in Chapter 4.

Another major barrier is the prevailing reimbursement arrangement for health care services, which does not reimburse care providers differentially on the basis of quality of care. At the present time, several factors severely undercut the returns health care providers might expect to capture on their investments.

As results are entered, the next steps in the care process are instituted.Health IT Workforce Curriculum Health Management 10 Information Systems Version /Spring This material was developed by Duke University funded by the Department of Health and Human Services, Office of the National Coordinator for Health Information Technology under Award Number 1U24OC 5.

The Health Catalyst Data Operating System (DOS) is a breakthrough engineering approach that combines the features of data warehousing, clinical data repositories, and health information exchanges in a single, common-sense technology platform.

Eligibility; Department of Defense; DoD Task Force on Mental Health—have concluded that the number of mental health care professionals in the military health care system is too low to meet current needs. 4 Information and Communications Systems: every one of these reports calls for the development of a comprehensive health care information infrastructure (e.g., NHII) to help close the gap (IOM, Information and Communications Systems: The Backbone of the Health Care Delivery System - Building a Better Delivery System.
