Below is the organizational scheme or architecture which categorizes data for clinical health services within the UHC Compendium. The architecture draws on several international classification systems, including the Global Burden of Disease (GBD), the International Classification of Diseases (ICD-11) and International Classification of Primary Care (ICPC-3) , which provide organizational structure and nomenclature for diseases in relevant Groups and Subgroups. GBD groups are utilized to identify intervention categories where relevant, and Level 2, 3 and 4 Causes are linked to interventions throughout the Compendium. The International Classification of Primary Care (ICPC-3) provides the structure and nomenclature for common presentations found in the foundations of care section including symptoms and syndromes.
Six broad classification groups are utilized and include: foundations of care; reproductive and sexual health; growth, development, and ageing; communicable diseases; violence and injury; and non-communicable diseases. Within these groups, subgroups and intervention categories have been identified to characterize and address the major disease burden. The structure is designed to assist countries in identifying, in a context-appropriate manner, the interventions needed for a UHC package.
Interventions include processes of health promotion, prevention, diagnosis, treatment, and/or management of disorders. Interventions have been aligned with the International Classification of Health Interventions (ICHI) definition and are:
-- undertaken with the objective of improving human health by promoting healthy behaviours, preventing disease, screening for disease or injury, by curing or reducing the severity or duration of an existing disease, or by restoring function lost through disease or injury; and
-- further defined by a group of minimally divisible set of actions, which often can be implemented together to a clearly defined population in need.
Actions are health services that have implications for resources and costing. They can be further subdivided into discrete “tasks" that link to resource inputs that include products and health workforce requirements. (Resource inputs will be available in 2021)
