2.2 Factors relating to physical environment

Main inclusion criteria

Environmental or external factors associated with the cause, risk or development of disease, conditions or ill health including:

  • physical agents, occupational hazards, environmental surroundings, radiation and pollution
  • chemicals and nutrients
  • infection by pathogens and studies of infectious agents

 

Advice on research activities

Involves characterising or identifying environmental or external factors that are determinants in the cause of conditions or disease e.g. studies of infectious agents.

Many studies will involve investigating the impact of environmental factors on biological systems. It may be appropriate to code to both 2.1 Endogenous risks as well as 2.2 Physical risks if the study involves investigating both the external agent and the biological response to that agent.

Excludes studies of infection with prion protein which should be coded as 2.1 Endogenous risks.

Excludes characterisation of antibiotic resistance genes and mechanisms in bacteria which should be coded as 5.1 Pharmaceuticals.

Common Scientific Outline (CSO) – 2.1 Exogenous Factors in the origin and cause of cancer
Common Scientific Outline (CSO) – 2.3 Interactions of Genes and/or Genetic Polymorphisms with Exogenous and/or Endogenous Factors

Main inclusion criteria

Identification and characterisation of endogenous factors known or suspected to be involved in the cause, risk or development of disease, conditions or ill health including

  • genes and gene products, molecular, cellular and physiological structures and functions
  • biological factors linked to ethnicity, age, gender, pregnancy and body weight
  • endogenous biological factors or pathways involved in responses to infection or damage by external factors
  • metastases, degenerative processes, regeneration and repair
  • complications, reoccurrence and secondary conditions
  • bioinformatics and structural studies
  • development and characterisation of models

 

Advice on research activities

To be used to code all biological causes of disease including the following

  • Host cell biological responses to infection
  • prion/TSE aetiological studies
  • ischemic preconditioning

Characterisation of pathways to identify candidates that may potentially be used as diagnostic markers should be coded as 2.1 Endogenous risks and not 4.1 Marker discovery.

Characterisation of the biological cause of psychological conditions should be coded as 2.1. However 2.3 Psychological risks can also be used if the study includes investigation of symptoms and characteristics of the psychological condition.

Awards that are focused on therapeutic development or diagnostics will often yield information about the mechanism of a disease. However, this is generally a secondary outcome and shouldn’t be coded 2.1 unless this is clearly stated as one of the primary objective of the research.

Excludes basic immune and pain responses and wound healing studies that are not linked to a specific disease/condition stimulus and normal ageing or pregnancy not linked to a condition which should be coded as 1.1 Biological normal function.

Excludes normal cell cycle and normal DNA repair and replication which should be coded as 1.1 Biological.

Main inclusion criteria

Development of novel underpinning research measures and analytical methodologies including

  • development of statistical methods and algorithms for genomic analysis
  • development of mapping methodologies and novel data comparison methods
  • development of biological, psychological and socioeconomic research measures

 

Advice on research activities

Methodologies and measurements linked to normal functions. This code may include algorithms for informatics research.

Includes the development and publication on the web of these tools as an outcome of a research project – this is not considered a resource for the community and shouldn’t be coded as 1.5 Underpinning resources.

Main inclusion criteria

Research in chemical and physical sciences that may lead to the future development of diagnostic tools or medical treatments including

  • bioengineering and biophysics
  • chemical structures, interactions and properties
  • molecular modelling
  • material science

 

Advice on research activities

For coding all basic chemical, physical and bioengineering research including development of therapeutics or diagnostics underpinning 4 Detection and Diagnosis or 5 Treatment Development code groups.

Main inclusion criteria

Studies that do not address health directly but cover issues that may have a bearing on health and well-being including

  • perception, cognition and learning processes
  • social and cultural beliefs
  • individual or group characteristics and behaviours
  • politics, economies and urban development
  • development and characterisation of model systems

 

Advice on research activities

This includes all normal psychological studies of behaviour, memory and cognitive processes. If the study also involves mapping brain structure it should be double coded 1.1 Biological and 1.2 Psychological and, correspondingly, 50% Neurological and 50% Mental Health.

Excludes studies investigating psychological disorders, however it may be appropriate for studies using patients as controls to understand normal function.

Main inclusion criteria

Testing and evaluation of therapeutic interventions in clinical, community or applied settings.
 

Advice on research activities

Research coded within this code group should involve patients in the testing and evaluation of therapies or be in a clinical or applied setting.

Note not all trial evaluation is in 6 Treatment Evaluation, only if the trial relates to treatment evaluation.

Clinical trials in this category will often involve an economic evaluation and quality of life component. Unless one of the primary aims of these trials is assessing quality of life or health economics, just code for the therapy under investigation.
