List of MeSH codes

|thumb|Database]] MeSH Codes are a comprehensive hierarchical controlled vocabulary used for indexing journal articles and books in the life sciences. Created and updated by the United States National Library of Medicine (NLM), MeSH (Medical Subject Headings) facilitates searching and organizing of biomedical and health-related information.

Overview

MeSH codes serve as a standardized set of terms, allowing for a common understanding and organization of information across various databases and platforms. These codes categorize information into a broad array of subjects such as anatomy, biochemistry, diseases, drugs and chemicals, and psychiatry. Each MeSH term is assigned a unique identifier, often referred to as a MeSH code, which can be used to search for articles and resources related to that term.

Structure

The structure of MeSH codes is hierarchical, with more general terms positioned at the top and more specific terms beneath them. This hierarchy is divided into several categories, including:

• Anatomy - covering terms related to body parts and structures.
• Organisms - for classifications of living things.
• Diseases - encompassing various health conditions and diseases.
• Chemicals and Drugs - detailing chemical compounds and pharmaceuticals.
• Analytical, Diagnostic and Therapeutic Techniques and Equipment - including terms related to medical procedures, equipment, and methodologies.
• Psychiatry and Psychology - covering mental health and behavioral sciences.
• Biological Sciences - for terms related to biology and life sciences.

Application

MeSH codes are primarily used in the indexing of journal articles, book chapters, and other literature in the MEDLINE/PubMed database, as well as in other NLM databases. Researchers and healthcare professionals use these codes to perform precise searches, ensuring that they retrieve relevant information. For example, by using the MeSH code for a specific disease, a researcher can find all articles related to that condition.

Updating and Maintenance

The NLM updates the MeSH database annually to reflect changes in the biomedical field and to add new terms. This ensures that the vocabulary remains current and comprehensive, accommodating new discoveries and trends in health and science.

Access

MeSH codes can be accessed through the NLM's website, where users can search for terms, explore the hierarchy, and learn more about the structure and application of MeSH. This resource is freely available, making it an invaluable tool for students, researchers, and professionals in the health sciences.
