HIV Prevention Indicators: Rationale: 

HIV Prevention Indicators: Rationale To evaluate and monitor the effectiveness of prevention activities (through use of appropriate markers). To monitor changes in clinical spectrum of disease which may be relevant to HIV transmission (transmissibility and infectivity) To monitor other factors which influence the spread of infection within the community and are targeted by prevention activities Sexual behaviour Access to and use of health care

HIV and STIs in men who have sex with men: Summary of prevalence and incidence data: 

HIV and STIs in men who have sex with men: Summary of prevalence and incidence data Background HIV prevalence is increasing due to both a decrease in deaths and an increase in new diagnoses. There have been large increases in STIs, particularly gonorrhoea in recent years. There is no evidence of a decrease in undiagnosed HIV prevalence in GUM clinic attenders aged under 25. This is considered a marker of recent HIV incidence. There has been an increase in HIV positive men presenting at GUM clinics with an acute STI.

Recent trends in Risk Behaviour:Summary of surveys of Gay men: 

Recent trends in Risk Behaviour: Summary of surveys of Gay men The proportion of gay men in London reporting sero-discordant UAI in the past year has increased. A higher proportion of HIV positive men reported discordant UAI in the past three months than HIV negative men. Reported condom failure decreased between 1998 and 2000. The consistency of these results in both community studies carried out in bars and at national pride surveys suggests a true trend is been observed.

Health Care Utilisation: GUM Clinic attendance and HIV test in last year in men who have sex with men in London Dodds J, Mercey D. Monitoring high risk sexual behaviour amongst gay men in London. 2000 New episodes seen at GUM clinics

Trends in health care utilisation: 

Trends in health care utilisation Median annual CD4 counts have risen dramatically following HIV diagnosis indicating the success of antiretroviral therapy. The number of AIDS cases has decreased, however the number of men first testing HIV positive at AIDS diagnosis has remained the same. The number of HIV tests in men who have sex with men is increasing overall.

Conclusions: 

Conclusions Existing surveillance systems contain relevant data that can be used to monitor prevention outcomes. The integration and review of this data can facilitate more effective HIV prevention and community planning. A comparison of all the Prevention Indicator estimates can aid the interpretation of programme effectiveness by providing a quantitative, although incomplete, picture of outcomes of activities to prevent HIV transmission. A close assessment including a contextual analysis is required before conclusions about the impact of programme activities on outcomes can be drawn.
