HIV surveillance in key populations
October 24, 2022 @ 8:00 am - October 28, 2022 @ 5:00 pm UTC+0
24-28 October 2022
Description
The aim of the course is to provide participants with practical guidance on how to design bio-behavioural HIV surveys and conduct estimation of the size of key populations (female sex workers [FSW], people who inject drugs [PWID], men who have sex with men [MSM]) and transgender persons), conduct these studies, and analyze, interpret and use the data. The course will outline the approaches that can be used for extrapolating local data to develop national size estimates by applying various adjustments.
The course will provide a detailed outline of design of integrated bio-behavioural HIV surveys (IBBS) that are based on time-location (TLS) and respondent-driven sampling (RDS). Presentations and exercises will address a number of issues relevant for the appropriate implementation of IBBS, data analysis and construction and interpretation of key indicators.
Presentations will also reflect on various methods of population size estimation (PSE) that are most commonly used, including the emerging new approach of virtual mapping.
The course will also describe how to generate HIV prevention and treatment casedes in KPs, using IBBS, PSE and and routine programme data.
Lectures will be followed by discussions about case studies to enable interactive exchange of knowledge and experiences.
Key topics of the course are:
- Design and implementation of TLS and RDS
- Methods used to estimate the size of KPs: mapping (including mapping of virtual platforms); multiplier method; two and three-source capture-recapture;
- Circumstances when it is appropriate to use specific size estimation methods
- Extrapolation from local size estimation to sub-national and national estimates using extrapolation procedures
- Data quality challenges in IBBS and PSE studies
- Framework for HIV prevention and treatment cascade
- Use of HIV cascades as management tools that identify gaps and related barriers and as advocacy tools for indicating points for intervention to enhance programme effectiveness
Participants will be given opportunities to share their own country-specific experiences and challenges in IBBS and estimating the size of KPs.
Key aspect of the course is a group/individual work on development of protocols/ proposals. Participants can choose between these options:
- To develop a protocol for an IBBS or a PSE study
- To construct HIV prevention or treatment cascades using their own data
Participants will present the results of this work on the final day of the course.
Teaching Methods
The course consists of lectures, presentation of case studies, active class discussion, exercises and group work. The course is designed to provide participants with practical skills and knowledge on how to conduct size estimation studies.
Target Audience
Epidemiologists, demographers, public health professionals, social scientists
Venue
The course will be held in Zagreb, Croatia.
