Tools & Standards * CoDe
The CoDe Project
The CoDe project was initiated out of the need to harmonize and standardize the approach taken when collecting data and reviewing the causes of death in HIV-1 infected patients. This has become increasingly necessary as a significant proportion of deaths in HIV-1 infected persons are now caused by non-AIDS events, many AIDS defining illnesses are poorly identified in the ICD system, and some diseases (e.g. CNS diseases) have a different aetiology in HIV patients and are therefore not covered by the ICD system, or at great risk of mis-classification.

The CoDe Project is a uniform coding system that can be applied to studies of individuals with HIV infection, including a detailed data collection o­n the causes of death and contributing factors, as well as a centralized review process of the data collected.

Anyone wishing to implement CoDe is free to do so. Permission is not required. Please see page 6 of the Protocol for more information.
