Health Information Technology and Healthcare Information System01:30

Health Information Technology and Healthcare Information System

Health Information Technology (HIT)
Health Information Technology, commonly called HIT, integrates advanced information systems and technology in healthcare settings. Its primary functions include:
Integrated Healthcare System01:20

Integrated Healthcare System

An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...
Healthcare Agencies II01:17

Healthcare Agencies II

There are various healthcare agencies in the United States—some of which are managed by religious institutions and others by different government branches.
Parish nursing is a growing specialty nursing profession that focuses on holistic healthcare, health promotion, and illness prevention. It blends professional nursing practice with a health ministry, focusing on health and healing within the context of a Christian community. Parish nurses serve as health educators, referral sources, and lay...

Purpose of Health Records II

Health records serve various essential purposes in the healthcare system. Here are some key purposes:
Healthcare Agencies I01:18

Healthcare Agencies I

Healthcare agencies provide healthcare services to people. In the United States, voluntary agencies are often non-profit centers sponsored by donations, grants, or fundraisers. One such organization is Meals on Wheels, which provides meals to the elderly and homebound. The American Heart Association and the American Lung Association are other non-profit community organizations. Doctors and nurses are frequently active members of these organizations, which offer health checks and educational...
Issues And Trends In Healthcare Delivery System01:29

Issues And Trends In Healthcare Delivery System

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Area of Science:

  • Health Informatics
  • Semantic Web Technologies
  • Data Interoperability

Background:

  • Heterogeneous health information systems pose significant data exchange challenges.
  • Lack of standardized methods hinders efficient health data interoperability.
  • Electronic Health Records (EHRs) often operate in isolated, incompatible environments.

Purpose of the Study:

  • To propose and describe a Resource Description Framework (RDF)-based mediator.
  • To address the health data interoperability problem among diverse health information systems.
  • To enhance the efficiency of health information exchange.

Main Methods:

  • Developed an RDF-based mediator framework with three core components.
  • Implemented a Synonym Dictionary (SD) for metadata semantic mapping.
  • Integrated CXTR module for XML to RDF-XML translation and CRTX module for RDF-XML to XML translation.

Main Results:

  • The proposed mediator framework facilitates semantic mapping of metadata.
  • Enables seamless translation of health documents between XML and RDF-XML formats.
  • Demonstrates a viable solution for overcoming health data silos.

Conclusions:

  • The RDF-based mediator effectively tackles health data interoperability issues.
  • The framework enhances the efficiency and accuracy of health information exchange.
  • This approach offers a scalable solution for integrating disparate health information systems.
