A Method for Constructing a New Extensible Nomenclature for Clinical Coding Practices in Sub-Saharan Africa

Area of Science:

• Health Informatics
• Medical Coding Systems
• Public Health Data Management

Background:

• Clinical coding is crucial for healthcare data in sub-Saharan Africa, supporting billing, epidemiology, and resource allocation.
• Current coding systems are often limited to billing and perceived as complex for daily clinical use.
• There's a growing recognition of the need for effective clinical data coding across health insurances, governments, and hospitals in the region.

Purpose of the Study:

• To develop a novel clinical nomenclature for sub-Saharan Africa that balances clinical impact with practical usability.
• To adapt existing coding systems by identifying a minimal, relevant subset for the region.
• To ensure the nomenclature's completeness and applicability for national health registries.

Main Methods:

• Constructing a new nomenclature by selecting a minimal subset from existing coding systems relevant to sub-Saharan Africa.
• Incorporating an extension character to manage codes applicable across multiple national registries.
• Evaluating the nomenclature's completeness against national registry requirements.

Main Results:

• A new, simplified clinical nomenclature tailored for sub-Saharan Africa has been developed.
• The nomenclature is designed for practical daily use, addressing complexity concerns.
• An extension character facilitates multi-registry data management, benefiting hospitals.

Conclusions:

• The proposed nomenclature offers a practical solution for enhancing clinical data utility in sub-Saharan Africa.
• This approach supports both billing and clinical decision-making, improving health information systems.
• The system is adaptable and beneficial for hospitals and national health data management.
