The aim of this workshop is to provide participants with theoretical knowledge and practical skills in implementation of HIV surveillance methods in high-risk groups, as well as methods used to carry out studies that aim to evaluate HIV prevention interventions in high-risk groups.

The first part of the course gives an overview of the components of a comprehensive HIV surveillance in high-risk groups, such as pre-surveillance assessment, mapping, and surveys that are implemented as part of the community-based surveillance. Study designs that will be described include cluster-based stratified sampling, time-location sampling and respondent-driven sampling. Advanced methods in HIV surveillance will be also outlined, such as HIV incidence-based surveillance and data triangulation as a programme evaluation tool.

In the second part of the course participants are provided with practical guidance on how to use different study designs to evaluate HIV interventions that are implemented in their countries among key populations at higher risk.

The most important part of the course is the protocol development exercise. Participants can choose to develop two types of protocols: (I) a protocol for an HIV surveillance survey in high-risk groups; or (II) a protocol for a study that evaluate HIV intervention(s) in high-risk groups using simple (cross-sectional surveys, programmatic data) or more complex designs (cohort studies, randomised control trials, data triangulation). Participants are encouraged to work on protocols that might be later on used in their own countries.

The increases in funding for HIV prevention and surveillance provided by the Global Fund for AIDS, Tuberculosis and Malaria and the (US) President’s Emergency Plan for AIDS Relief (PEPFAR), increased also the imperative and the opportunities for evaluation of the scaled-up HIV interventions among key populations at higher risk of HIV.(1) HIV transmission can be decreased if prevention programmes include a mix of behavioural, biomedical and structural interventions appropriate for the epidemic context. (2) (3) Evaluation of HIV programmes enables to document how improvements in availability, access, utilization, and coverage with HIV interventions result in decreased rates of HIV infection.(4)

The aim of this course is to provide participants with practical guidance on how to set up an evaluation plan for HIV interventions implemented among key populations at higher risk (sex workers, injecting drug users, men who have sex with men) and other vulnerable groups.

The course starts with the outline of the current evidence of effectiveness of biological, behavioural and structural HIV prevention strategies, obtained mainly from systematic reviews and meta-analysis. The lectures on the second day will outline the key sources of evidence on effectiveness of interventions, such as Cochrane Collaboration and latest WHO and CDC recommendations and guidelines. (5) (6) (7) Participants will be given an opportunity to share their own country-specific experiences of evaluation of HIV programmes among populations at higher risk of HIV on the first and the second day.

The next part of the course will present the simple approaches to designing HIV evaluation protocols, which rely on programmatic and surveillance data, and more complex approaches which use prospectively collected data, step-wedged and randomized trial designs. The issues to be addressed include the selection of the study population, sampling, statistical inference and measuring outcomes and impact.  The key part of the course is a group work which consists of the development of an evaluation protocol that participants will present at the end of the course. Participants can choose the topic of the evaluation protocol which they can later on use in their countries. An evaluation protocol describes every step of the evaluation, with special focus on the design, methodology, and analytical procedures of the evaluation.
