Background/introduction General practice (GP) offers a wide range of sexual health services, although provision varies across England. Educational support visits to GPs are effective in improving sexual health services. 3Cs and HIV is a national pilot that provided GP training for opportunistic offers of chlamydia testing, free condoms and information about contraceptive services to 15–24 year olds (i.e. 3Cs), plus HIV testing according to national guidelines.

Aim(s)/objectives To describe local authority (LA) and GP engagement with the 3Cs and HIV pilot using process evaluation measures.

Methods The training programme comprises two practice educational support visits, the first on 3Cs and the second on HIV testing. Data on LA and GP recruitment, retention and implementation of the training was collected throughout the programme.

Results In total, 56 LAs invited 2,532 practices to the programme, 461 agreed to participate. Data was returned by 46 LAs accounting for 405 practices (88%). Half of participating practices received at least one visit (255/461, 55%). Nearly a third of practices received only the 3Cs visit (143/461, 31%) and 24% (111/461) received both the 3Cs and HIV visits. More general practitioners than nurses attended the training (826 vs. 752), especially for the HIV sessions (263 vs. 211).

Discussion/conclusion Many practices reported an interest in receiving sexual health educational support visits, however a large proportion did not start or complete the full programme. This highlights the difficulties sustaining GP engagement over time, which may be due to competing priorities for protected learning time. Future programmes may need to be shorter.
