Injecting drug usersArchived
In Europe, behavioural surveillance has mainly been conducted using service-based or community-based sampling.
Table 1. below provides selected features of available methods for collecting behavioural surveillance data among IDU.
The second table presents the best three methods proposed by the experts according to two different contexts.
Table 1. Selected features of available methods for collecting behavioural data among IDU
Design | Advantages | Disadvantages | Comments |
---|---|---|---|
Service & venue based approaches* |
|
|
Variations on this approach have been adopted for surveillance sys-tems in several countries (inc. France, UK and Australia), relati-vely low cost and sustainable |
Community based - outreach sampling |
|
|
This approach has been used in research studies in many locations worldwide , and used in some surveillance studies |
Community based - snowball sampling |
|
|
This approach has been used in research studies in many locations worldwide , and used in some surveillance studies |
Time location sampling |
|
|
This approach has mostly been used for research and evaluation studies in some developing and transitional countries |
Respondent driven sampling |
|
|
This recent approach has been used in a number of research studies worldwide |
Treatment demand indicator |
|
|
Used in a number of European countries, though often accom-panied by other systems (to provide more in depth information and/or corroboration) |
*including recruitment through: low-threshold services; treatment services; community venues; and/or social services
The second table presents the best three methods proposed by the experts according to two different contexts:
- the population is reachable in known settings and is not severely stigmatised
- the population is not very well known, not easy to reach, and/or stigmatised
Examples of good practice are provided (references)
