An innovative HIV-testing strategy is developed based on mathematical modeling results on undiagnosed HIV and being implemented in primary care settings in Belgian's Flemish region. The systematically developed intervention aims at increasing the number of targeted HIV tests in primary care in order to identify people with undiagnosed HIV. The intervention tool is an HIV-screening advice targeting general practitioners (GPs), combining indicator-condition based screening and target-group based screening. A group-level training to apply this advice in routine practice is being delivered as part of the continuing medical education through GP-associations. The intervention is implemented across Flanders adopting a modified stepped wedged design: two different intervention levels (delivering written/online information on the HIV testing advice versus information plus group-level training) are being compared with a control condition (no intervention, i.e. standard practice) based on surveillance data. A mixed-method study evaluates the intervention's effectiveness, feasibility, and acceptability.
