Wedge-Shaped Clusterded Randomizad Trial to Evaluate Two Tools to identify People at Risk or already Infected with HIV and HCV

Objectives: To reduce hidden and incident HIV and HCV infection, through the implementation of a risk and indicator conditions self-questionnaire SQ-R&IC for HIV and HCV infection, in addition to rapid HIV and HCV serological tests (RT), in the Health Centers (HC). Methodology: stepped-wedge cluster randomized trial in 8 CS of the community of Madrid, to to know if the implementation of the 2 tools described above, improve risk identification and subsequent screening for HIV and HCV infection. In the standard of care branch (SOC), the health personnel will ask people a series of questions to identify the HIV risk exposition, and also they will be provided pop-up computer alerts of HIV indicator conditions in the electronic medical record, moreover HIV and HCV serological tests will be carried out in the reference laboratory, while in the intervention branch in addition to the SOC, a SQ-R&IC of HIV and HCV will be made available to the HC population, through a quick response (QR) code, as well as HIV and HCV RT. The variables that will be compared are the percentage of HIV and HCV tests performed, of people referred to receive PrEP, and of new HIV and HCV diagnoses or not linked to care that are made during the periods assigned to the EDC branch vs. those in the intervention branch.
