BRADFORD HILL SEMINAR

Since Gardner and colleagues first described the steps that make up the continuum of HIV care in 2011, the so-called ‘Cascade of Care’ (CoC) has been reported from many different settings and patient groups. Although the CoC is a relatively simple concept, estimation of the numbers of people living with HIV at each step of the cascade is not always straightforward and methodological approaches frequently differ, with little consensus on an optimal approach. Thus, comparisons of the CoC from different settings/population groups are likely to be biased. This talk will describe some of the methodological difficulties that are encountered when applying the CoC to routinely collected data, with a particular focus on the measures used to assess retention-in-care (RIC). The talk will be illustrated using data from the UK Collaborative HIV Cohort (UK CHIC ).

Chaired by Dr Daniela De Angelis.

This talk is part of the Bradford Hill seminars at the Cambridge Institute of Public Health series.
