The Collaboration of Observational HIV Epidemiological Research Europe (COHERE) was formed in 2005 to pool and harmonize existing longitudinal data on HIV-positive persons collected across Europe to answer key research questions that, in the era of potent combination antiretroviral therapy (cART), could not be addressed adequately by individual cohorts.  COHERE uses the HIV Cohorts Data Exchange Protocol (HICDEP), a standardized and validated method of data structure and transfer, to compile data from 40 cohorts of HIV-infected people residing in Europe, representing ~300,000 HIV-positive persons, and over 2 million person-years of follow-up. Mergers of data for approved projects are conducted annually. COHERE compiles data on clinical characteristics, antiretroviral therapy and other medications, HIV seroconversion, opportunistic infections, and laboratory results (CD4-positive T-lymphocyte counts, CD8-positive lymphocytes, viral load, virological and serological tests for other infections, and HIV resistance tests) and socio demographic data.  COHERE projects have thus far focused on long-term prognosis, rare outcomes and variations across patient groups, settings and health systems.  

The Cohere Collaboration has been described in its International Journal of Epidemiology Cohort Profile
