Health Information Technology and Healthcare Information System

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:

Anatomical Terminology

Anatomical Terminology

Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Issues And Trends In Healthcare Delivery System

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...

Integrated Healthcare System

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,...

Methods of Documentation I: Source-Oriented Records

Methods of Documentation I: Source-Oriented Records

Source-oriented records, or SOR, are medical record-keeping organized by the data source. The SOR system was first developed in the mid-1900s to organize the growing patient data in hospitals and other healthcare facilities.
In an SOR, each discipline involved in patient care maintains a separate medical record section. This record-keeping method enables easy tracking of patient progress and ensures healthcare staff have access to up-to-date information.
Key Attributes include the following:

Area of Science:

Health Informatics
Data Science
Ontology Engineering

Background:

The health data ecosystem is complex, with diverse, heterogeneous data sources (clinical, social, etc.).
Data exist as structured or free-text, often proprietary or using isolated coding systems.
Semantic interoperability issues hinder effective data integration across different health systems.

Purpose of the Study:

To address semantic interoperability challenges in the health data ecosystem.
To present a classification of semantic interoperability issues.
To propose a four-step process and toolkit for developing health data ontologies.

Main Methods:

Identification and specification of data sources.
Conceptualization of semantic meaning.
Defining the utility of routine data for care process/outcome measurement.
Formalization and validation of the final ontology.

Main Results:

A classification of semantic interoperability challenges is presented.
A four-step process for ontology development is proposed.
A toolkit, extending a previous schema, facilitates ontology building for time-critical research.

Conclusions:

The proposed process and toolkit aim to improve ontological work in health data integration.
This approach supports the rapid development of ontologies for research, especially in time-sensitive studies.
Addressing semantic interoperability is crucial for leveraging the full potential of health data.
