RESUMO
UNLABELLED: Background In July 2010, the Western Australian AIDS Council established the 'M Clinic', a peer-led STI testing service for MSM. This study describes trends in HIV notifications among MSM in WA from 2004 to 2013, particularly the impact of the M Clinic on newly acquired HIV diagnoses. METHODS: The number and proportion of MSM HIV cases with newly acquired infection were compared for the 2004-2006, 2007-2009 and 2011-2013 time periods. Data from 2010 were excluded as the M Clinic opened in July 2010. RESULTS: Between the 2004-2006 and 2007-2009 periods, the number of MSM with newly acquired HIV increased by 50% (23 to 33 cases) and the number of newly acquired cases as a proportion of all new HIV diagnoses among MSM increased from 27% to 35% (30% increase) (P=0.25). In the 2011-2013 period, the number of newly acquired HIV cases among MSM more than doubled to 70 cases and comprised 53% of all new HIV diagnoses among MSM (P<0.05). Of the 70 newly acquired HIV cases in the 2011-2013 period, 30% (n=21) were diagnosed at the M Clinic. CONCLUSIONS: The proportion of MSM HIV notifications that were newly acquired increased between 2004 and 2013 in WA, with the greatest increase seen after the M Clinic commenced operation. A peer-led approach to HIV testing should be considered in order to achieve early diagnosis and treatment of HIV among MSM.
