Abstract
We assessed whether implementation of a combination of interventions in London tuberculosis clinics raised the levels of HIV test offers, acceptance and coverage.A stepped-wedge cluster randomised controlled trial was conducted across 24 clinics. Interventions were training of clinical staff and provision of tailor-made information resources with or without a change in clinic policy from selective to universal HIV testing. Primary outcome: HIV test acceptance amongst those offered a test, before and after the intervention; Secondary outcome - offer of HIV testing. Additionally, the number and proportion of HIV tests among all clinic attendees (coverage) was assessed.1315 patients were seen in 24 clinics. The offer and coverage of testing rose significantly in clinics without (p=0.002 and p=0.004 respectively) and with existing universal testing (p=0.02 and p=0.04 respectively) ofpolicy. However, the level of HIV test acceptance did not increase in 18 clinics without routine universal testing (p=0.76) or the 6 clinics with existing universal testing (p=0.40).The intervention significantly increased the number of HIV tests offered and proportion of participants tested, although acceptance did not change significantly. However, the magnitude of increase is modest due to the high baseline coverage.
