Testing rates for sexually transmitted infections among HIV-infected men who have sex with men attending two different HIV services

Abstract

Summary This study compares the testing rates of bacterial sexually transmitted infections (STIs) among HIV-positive men who have sex with men (MSM) attending two HIV clinics in Melbourne. Data on STI testing over a 12-month period were obtained for all HIV-positive MSM who attended the clinics between January and March 2006. Screening rates for bacterial STIs were significantly higher at a sexual health clinic (n = 254) compared with an infectious diseases clinic (n = 351), whether this was measured according to: at least one STI test being performed for chlamydia, gonorrhoea or syphilis (69% vs. 38%, P < 0.01); serological testing for syphilis alone (67% vs. 34%, P < 0.01); or ‘complete’ STI screening for pharyngeal gonorrhoea, urethral chlamydia, anal gonorrhoea, anal chlamydia and syphilis (41% vs. 6%, P < 0.01). Substantial differences in STI testing rates among HIV-positive MSM may exist between HIV clinical services depending on the measures in place that promote STI screening.
