T11 – HIV Cascade Analysis Workshop

Description

The main objective of the workshop is to enhance the skills of participants in analysis of the HIV test–treat–retain cascade (“cascade”), which is used to determine the magnitude of the losses and gaps along the continuum of HIV care and to explore reasons for these losses.

The overall aim of the cascade analysis is to improve HIV services throughout the continuum of care, from diagnosis to achievement of viral suppression, and to assist country programmes to prioritize key indicators to assess in order to improve performance throughout the cascade of HIV services and transitions between services in a timely manner.

The workshop will outline data collection methods needed to assess four interlinked steps along the continuum of care (HIV testing, enrolment in HIV care and pre-antiretroviral (ART) care, and ART initiation and retention in lifelong HIV care) for a general population, pregnant women and key populations (KPs). These methods will include the collection of key quantitative and qualitative data, such as the total estimated number of persons living with HIV infection (PLHIV), HIV testing uptake, linkage to HIV care, ART treatment, retention and viral load suppression overall and among key populations. They also include the examination of factors that lead to patients being lost to follow up and the coverage gap such as availability of services, geographical accessibility, affordability, etc. Lectures will also address key limitations to using the cascade analysis and the importance of assessing quality of data and strengths and limitations of each data source when constructing the indicators relevant for the cascade.

Learning Objectives

  • Describe how to implement cascade analysis in countries, from establishment of a technical working group to data collection and analysis.
  • Understand data collection methods and types of qualitative and quantitative data that should be collected
  • Illustrate stratification of the cascade by sex, age groups, risk groups and geographic areas
  • Present examples of the HIV test–treat–retain cascade analysis done in a general population and in population sub-groups (pregnant women, people who inject drugs [PWID], men who have sex with men [MSM], sex workers [SW], young people, etc.)
  • Prepare a draft protocol for cascade analysis
  • Conduct cascade data analysis and propose interventions that address the gaps in the prevention and treatment continuum

Teaching Methods

The course consists of lectures, exercises and case studies. There will be two options for group work:

  • Option A – constructing a cascade for a general population or population sub-groups (pregnant women, MSM, PWID, etc.) by using most recent data from participating countries
  • Option B – a cascade analysis using illustrative data

 

Participants will present results of the cascade analysis during the workshop, followed by an open discussion about the reasons for such gaps in the continuum of care.

Target Audience

NAP managers, HIV surveillance officers, epidemiologists, public health professionals
