There are 21 separate categories which encompass all diseases, conditions and areas of health. Each of the Health Categories includes research into both disease and normal function. Of the 21 categories, 19 refer to specific areas of health or disease. The Generic Health Relevance category has been included to capture research that is relevant to all diseases and conditions or to general health and well-being. The Disputed Aetiology and Other category is included to code research that does not fit within the Generic Health Relevance category or the 19 health specific categories.
Haematological diseases, anaemia, clotting including thromboses and venous embolisms and normal development and function of platelets and erythrocytes. Cancer and neoplasms All types of neoplasms, including benign, potentially malignant, or malignant cancer cancer growths. This includes leukaemia and mesothelioma. Coronary heart disease, diseases of the vasculature and circulation including the lymphatic system, and normal development and function of the cardiovascular system.
Infection Diseases caused by pathogens, acquired immune deficiency syndrome, sexually transmitted infections and studies of infection and infectious agents. Rheumatoid arthritis, connective tissue diseases, autoimmune diseases, allergies and normal development and function of the immune system. Injuries and accidents Fractures, poisoning and burns. However, they have not generally been found easily usable at hospital levels, they are not always unique for a particular presenting condition depending on the hierarchical sequence followed to arrive at the final code , and their ethnic categories do not correspond with those used elsewhere.
Though they formed a major plank of an earlier NHS Information Strategy, they have not taken the place they were expected to. Within the UK these are standard codes used in hospital datasets to record surgical interventions. The most recent release is OPCS4, which dates from the s and is recognised as in need of revision.
However, there has as yet been no consensus as to the best form of replacement. DRGs are used for payment of hospitals by health insurance organisations, and HRGs are used by the NHS to set standard reimbursements for care carried out. HRGs are intended to group cases of similar clinical character and similar resource use, and as such can be a valuable tool for healthcare analysts concerned with appropriate targeting and utilisation of NHS resources. They are regularly reviewed and updated, and are currently at version 4.

Introduction Learning objectives: You will learn about the international and national classifications that are used for coding data and the strengths and weaknesses for using these classifications.
Read the resource text below. Classifications used in the NHS There are three types of classification which may be relevant for data collection and analysis. Navigation Population and demographic data Births and deaths Measuring health statistics Registries and condition specific data Primary care activity Secondary care activity Classification of diseases and medical care.
The latest version is DSM Read codes, or Clinical Terms, were developed initially for use in primary care. They have a hierarchical structure describing the care and treatment of patients, including diagnosis, symptoms, tests and other interventions and can mostly be mapped to ICD10 and OPCS4.
However, they have not generally been found easily usable at hospital levels, they are not always unique for a particular presenting condition depending on the hierarchical sequence followed to arrive at the final code and their ethnic categories do not correspond with those used elsewhere. Though they formed a major plank of an earlier NHS Information Strategy, they have not taken the place they were expected to. Read Version 2 and Clinical Terms Version 3 are due for retirement. The last updated release of Read v2 was April , and there will be no further update to CTV3 following the April release.
It describes health and health-related domains as body functions and structures, activities and participation. Because an individual's functioning and disability occur in a context, ICF includes a list of physical, social, attitudinal and environmental factors. Domains are classified from body, individual and societal perspectives.
The classification places emphasis on function rather than condition or disease. It's designed to be applicable across cultures, age groups and gender, making ICF the basis for collecting reliable and comparable data on health outcomes for individuals and populations.
The World Health Assembly approved ICF in May after a decade-long international revision process involving 65 different countries.
ICF is designed for better, more uniform data for research and analysis. It will eventually be implemented worldwide, meaning that health and disability can be described and measured more effectively, and that the impact of these conditions can be monitored. The Office of Populations, Census and Surveys as it formerly was, before becoming part of the Office of National Statistics produced classifications of operative interventions.
Within the UK these are standard codes used in hospital datasets to record surgical interventions.
