Percentage of people who inject drugs reporting the use of sterile injecting equipment the last time they injected
It measures progress in preventing injecting drug use-associated HIV transmission
Safer injecting and sexual practices among people who inject drugs are essential, even in countries where other modes of HIV transmission predominate, because: (i) the risk of HIV transmission from contaminated injecting equipment is extremely high; and (ii) people who inject drugs can spread HIV (e.g., through sexual transmission) to the wider population.
Note: Countries with generalized epidemics may also have a concentrated sub-epidemic among people who inject drugs. If so, it would be valuable for them to calculate and report on this indicator for this population.
Number of respondents who report using sterile injecting equipment the last time they injected drugs.
Number of respondents who report injecting drugs in the last month.
Surveying people who inject drugs can be challenging. Consequently, data obtained may not be based on a representative sample of the national injecting drug user population being surveyed. If there are concerns that the data are not based on a representative sample, these concerns should be reflected in the interpretation of the survey data. Where different sources of data exist, the best available estimate should be used. Information on the sample size, the quality and reliability of the data, and any related issues should be included in the report submitted with this indicator.
The extent of injecting drug use-associated HIV transmission within a country depends on four factors: (i) the size, stage and pattern of dissemination of the national AIDS epidemic; (ii) the extent of injecting drug use; (iii) the degree to which people who inject drugs use contaminated injecting equipment; and (iv) the patterns of sexual mixing and condom use among people who inject drugs and between people who inject drugs and the wider population. This indicator provides information on the third factor.
To maximize the utility of these data, it is recommended that the same sample used for the calculation of this indicator be used for the calculation of the other indicators related to these populations.
