<p>- The International Collaboration on Hepatitis C Elimination in HIV Cohorts (InCHEHC) is a multinational consortium of longitudinal cohorts of people with HIV who are at risk of hepatitis C virus (HCV) infection or infected with HCV. InCHEHC has been specifically designed to assess progress towards HCV elimination as a public health threat among people with HIV.</p>
<div>- The first data merge includes 104 740 participants from 11 cohorts in Australia (<em>n</em> = 22 033), Canada (<em>n</em> = 2070), France (<em>n</em> = 18 387), The Netherlands (<em>n</em> = 24 785), Spain (<em>n</em> = 16 725) and Switzerland (<em>n</em> = 20 740), with data collected between 1987 and 2021. Participants include 86 132 males (81.4%), 19 514 females (18.4%) and 191 with unknown sex at birth (0.2%); 725 (1.0%) were known to be transgender across eight cohorts collecting data on this variable. At enrolment, the median age was 38 years (interquartile range: 30–46). Of the total 104 740 participants, 12 784 (12%) had an HCV antibody or RNA positive test at or up to 1 year prior to individual cohort enrolment; 32 360 (31%) did not have an HCV RNA or antibody test recorded at that time. </div>
<p>- Clinical data are collected on all participants and behavioural and mortality data on a subset of them. Clinical data include HIV-related markers, HCV testing and treatment, liver health-related markers and sexually transmitted and blood-borne virus co-infections. Behavioural data include sexual and injecting risk behaviours and alcohol and drug use. Mortality data are collected using the International Classification of Diseases 9th or 10th revision (ICD-9/10) or Coding Causes of Death in HIV (CoDE) classification. </p>
