Summary
National extensions for SNOMED CT are utilized for content addition, reference set development, and cross-system mapping. Terminology management practices differ across countries due to unique healthcare environments and eHealth strategies.
Area of Science:
- Health Informatics
- Medical Terminology
- International Health Standards
Background:
- SNOMED CT is a comprehensive clinical terminology used globally.
- National member countries often develop extensions to meet specific local needs.
- Understanding terminology management is crucial for consistent healthcare data.
Approach:
- Surveyed 15 SNOMED CT national member countries.
- Investigated the use and characteristics of national extensions.
- Examined approaches to clinical terminology management.
Key Points:
- National extensions facilitate adding new content, creating reference sets, and mapping to other classifications.
- Terminology management composition and content are influenced by national healthcare environments.
- eHealth strategies and national release center infrastructure impact terminology management.
Conclusions:
- National SNOMED CT extensions are vital for localizing clinical terminology.
- Variations in terminology management reflect diverse national healthcare landscapes.
- Standardized yet flexible approaches to SNOMED CT are essential for global interoperability.

3.9K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

01:20Anatomical Terminology
12.6K
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,...

Trends in nursing are multifactorial and associated with changes in society, within the nursing profession, and in other professions. Notably, telehealth and remote nursing contribute to successful healthcare delivery for numerous patients and help reduce stress for nurses due to nursing shortages. Nurses can reach patients, monitor their conditions, and interact with them using computers, audio, visual accessories, and telephones—for example, remote patient monitoring systems. Likewise,...

Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
