A meta-analysis of condom effectiveness in reducing sexually transmitted HIV.

Weller SC.

Department of Preventive Medicine and Community Health, University of Texas Medical Branch, Galveston 77555-1053.

Before condoms can be considered as a prophylaxis for sexually transmitted human immunodeficiency virus (HIV), their efficacy must be considered. This paper reviews evidence on condom effectiveness in reducing the risk of heterosexually transmitted human HIV. A meta-analysis conducted on data from in vivo studies of HIV discordant sexual partners is used to estimate the protective effect of condoms. Although contraceptive research indicates that condoms are 87% effective in preventing pregnancy, results of HIV transmission studies indicate that condoms may reduce risk of HIV infection by approximately 69%. Thus, efficacy may be much lower than commonly assumed, although results should be viewed tentatively due to design limitations in the original studies.

So apparently in this instance 2 + 2 = 69%.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
