Comments
Comments:
This metadata item has been developed for use in clinical settings. A code that refers to a three-month period to define 'current' injecting drug use is required as a clinically relevant period of time.
The metadata item may also be used in population surveys that require a longer timeframe, for example to generate 12-month prevalence rates, by aggregating Codes 1 and 2. However, caution must be exercised when comparing clinical samples with population samples.
This metadata item is important for identifying patterns of drug use and harms associated with injecting drug use.
