Abstract
BACKGROUND: The study objective was to investigate the effect of the introduction of a sexual health practice nurse on HIV and STI testing in a general practice that specialized in gay men's health. METHODS: This observational study compared the proportion of gay and other men who have sex with men (MSM) tested for HIV, syphilis, chlamydia (urethral and anal) and gonorrhoea (anal), or all of the above (defined as a complete set of tests at a single visit), two years before and one year after the nurse was introduced (Clinic A). Clinic B, a general practice which also specialized in gay men's health, but with no sexual health nurse, was used as a control. RESULTS: In Clinic A, amongst HIV negative MSM the proportion of men who had a complete set of HIV and STI tests increased from 41% to 47% (p < 0.01) after the nurse was introduced. Amongst HIV positive MSM attending clinic A there was an increase in the proportion of men who had a complete set of tests after the nurse was introduced from 27% to 43% (p < 0.001). In Clinic B there was no significant increase in testing in the proportion of either HIV negative or HIV positive men who had a complete set of tests over the same time periods. CONCLUSIONS: The introduction of the sexual health practice nurse resulted in significant increases in episodes of complete STI testing among MSM. The effect was most pronounced among HIV positive MSM.
