The majority of patients across all sociodemographic groups are happy to be offered HIV tests irrespective of the clinical setting, the HINTS study has found. The study was set in four locations in London where diagnosed HIV prevalence exceeds 2 per 1,000: an emergency department (ED), an acute care unit (ACU), a dermatology outpatient clinic (OPD), and a large primary care centre (PC). In the first three settings, tests were offered by seconded local sexual health and permanent staff and a small number of non-clinical staff; only GPs were involved in the PC arm.
