Drug-related infectious diseases key (DRID) indicator
Drug-related infectious diseases key epidemiological indicator
Drug-related infectious diseases (DRID)
This key indicator collects data on the extent of infectious diseases — primarily HIV, hepatitis C and hepatitis B infection — among people who inject drugs (injecting drug users or IDUs). The data is collected from IDUs each calendar year using two main methods. These are: (a) surveys of IDUs that include serological testing and (b) the monitoring of routine diagnostic testing for HIV, hepatitis C and hepatitis B infection among IDUs.

Key methodological documents
DRID toolkit (November 2013)
The most recent work in DRID has resulted in a more flexible approach to DRID guidance, through a toolkit with modules and is principally aimed at professionals in the field. The first three modules were finalised in 2013 and cover:
- Behavioural indicators
A contextual complement to biological monitoring, covering risk and protective behaviours, testing, service uptake etc. - Example questionnaire
More detailed questions as applicable in national studies, including those that are needed to construct the behavioural indicators - Methods of bio-behavioural studies
Provides a short overview of methods and issues with regard to setting up monitoring through repeated studies in people who inject drugs
