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.

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
