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,...

Computed Tomography

Computed Tomography

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...

Methods of Documentation VII: EMR

Methods of Documentation VII: EMR

Electronic Medical Records (EMRs) primarily center around electronically documenting patients' health information within a single healthcare organization or practice. They contain essential clinical data related to a patient's medical history, diagnoses, medications, treatment plans, lab results, and other pertinent information relevant to the specific encounter or episode of care. EMRs are designed to streamline documentation and workflow processes within individual healthcare settings,...

Nursing Clinical Information System

Nursing Clinical Information System

Nursing Clinical Information System (NCIS)
A Nursing Clinical Information System (NCIS) is a specialized type of healthcare information system tailored to meet the unique needs of nursing practice. It incorporates the principles of nursing informatics to streamline information management and improve the quality of care delivery.
Critical attributes of NCIS include:

Imaging Studies I: CT and MRI

Imaging Studies I: CT and MRI

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Methods of Documentation VI: Case Management Model

Methods of Documentation VI: Case Management Model

The case management model is a multidisciplinary approach that involves healthcare professionals from diverse disciplines, such as physicians, nurses, therapists, social workers, and pharmacists, working collaboratively to address the various needs of patients. Each healthcare professional brings unique expertise and perspectives, contributing to a more comprehensive understanding of the patient's condition and tailoring treatment plans accordingly.
For example, a patient with a chronic illness...

Area of Science:

Health Informatics
Clinical Terminology Management
Medical Standards Development

Background:

Growing adoption of SNOMED CT as the standard clinical terminology.
Need for healthcare applications to migrate from legacy terminologies to SNOMED CT.
Challenges in mapping existing clinical data to SNOMED CT.

Purpose of the Study:

To describe a methodology for mapping legacy concepts to SNOMED CT.
To share experiences and lessons learned from a SNOMED CT mapping project.
To contribute to the refinement of SNOMED CT through practical application.

Main Methods:

Establishing clear mapping rules between terminologies.
Employing iterative, collaborative refinement of mapped results.
Achieving consensus on final concept maps through multiple review cycles.

Main Results:

Quantification of mapping success (number of matches, map quality).
Analysis of SNOMED CT characteristics, including post-coordination and multiple maps.
Identification of SNOMED CT inconsistencies, redundancies, and omissions.

Conclusions:

The developed methodology offers a valuable framework for SNOMED CT migration.
Lessons learned can assist other organizations facing similar terminology challenges.
Findings contribute to the ongoing improvement and standardization of SNOMED CT.
