Cascade data use manual: to identify gaps in HIV and health services for programme improvement

This guide supports the use of data to identify and fill gaps in services in order to improve HIV and health programmes. Following from the Consolidated Strategic Information Guidelines, high-level indicators are organized along a cascade of services which are linked to achieve outcomes. The guide supports the ways in which these cascade data are analysed and used to identify gaps and better link services.

This manual addresses not only the HIV care and treatment cascade but also cascades for HIV prevention interventions, such as prevention of mother-to-child transmission, and for co-infections with hepatitis B virus (HBV), hepatitis C virus (HCV) and tuberculosis (TB).

The use of cascades is integral to achieving the 90-90-90 global HIV targets and represents one of the key monitoring strategies for supporting expansion and linkage of HIV care, treatment and prevention services.
