Classification of Diseases
This domain focuses on organizing and categorizing various diseases and related health conditions into a structured system. It helps in the standardized classification of diseases, making it easier for healthcare providers, researchers, and health information systems to manage and use disease-related data consistently.
At the time of developing this, this domain had 35,766 concepts sourced from the International Classification of Disease 11th Revision - ICD11. This figure is prone to change since new concepts are regularly added and updated upon users' request. Refer to this page on how to request for concept addition
N/B: The process of navigating around a domain and viewing concepts is the same across all domains
Searching For Concepts
- Step 1- Search for a concept while anywhere within the TS
Use the Global search bar to search within the whole KNHTS.
Type your keywords in the Global Search field and click on the search link to search within the whole TS
- Step 2 - Search within a domain
Use the Search Bar within the opened domain to search for a concept attached to that domain
This type of search will only search what is within the visited domain

Organizations in KNHTS and any other Terminology Service are used to
- Manage terminology resources, such as concept dictionaries, classifications, and mappings. This includes overseeing the creation, update, and retirement of concepts within their domain.
- Collaborate with other entities, share terminology resources, and contribute to common terminology standards. This promotes interoperability and consistency across different systems and applications.
- Control access to terminology resources by defining user roles and permissions. This helps manage who can view, modify, or administer terminology data.
- Customize and localize terminologies to meet their specific needs or regional requirements. This includes adapting terminologies to reflect local practices, languages, or regulatory standards.
- Are responsible for ensuring that terminology resources adhere to governance, compliance, and quality standards. They oversee the accuracy and relevance of terminology data within their jurisdiction.
- Organizations engage with users and stakeholders to gather feedback, address issues, and make improvements to terminology resources. This ensures that terminologies meet the needs of their user base.
- Use terminology resources for integrating data from various sources and generating reports. This facilitates data analysis and decision-making based on standardized terminology.
