Sexually Transmitted Disease Prevention Policies in the United States: Evidence and Opportunities.

Policies are an important part of public health interventions, including in the area of STD prevention. Similar to other tools used in public health, policies are often evaluated to determine their usefulness. Therefore, we conducted a non-systematic review of policy evidence for sexually transmitted disease prevention. Our review considers assessments or evaluations of STD prevention-specific policies, health care system policies, and other, broader policies that have the potential to impact STD prevention through social determinants of health. We also describe potential policy opportunity in these areas. It should be noted that we found gaps in policy evidence for some areas; thus, additional research would be useful for public health policy interventions for STD prevention

Individualized diagnosis interventions can add significant effectiveness in reducing human immunodeficiency virus incidence among men who have sex with men: insights from Southern California

PurposeIn this article, we examine the effectiveness of a variety of HIV diagnosis interventions in recently HIV-diagnosed men who have sex with men (MSM). These interventions use the preventive potential of postdiagnosis behavior change (PDBC), as measured by the reduction in the number of new infections. Empirical evidence for PDBC was presented in the behavioral substudy of the Southern California Acute Infection and Early Disease Research Program. In previous modeling work, we demonstrated the existing preventive effects of PDBC. However, a large proportion of new infections among MSM are either undiagnosed or diagnosed late, and the preventive potential of PDBC is not fully utilized.MethodsWe derive empirical, stochastic, network-based models to examine the effectiveness of several diagnosis interventions that account for PDBC among MSM over a 10-year period. These interventions involve tests with shorter detection windows, more frequent testing, and individualized testing regimens.ResultsWe find that individualized testing interventions (i.e., testing individuals every three partners or 3 months, whichever is first, or every six partners or 6 months, whichever is first) result in significantly fewer new HIV infections than the generalized interventions we consider.ConclusionsThis work highlights the potential of individualized interventions for new public health policies in HIV prevention
