The authors note that interstudy and intercountry comparisons are complicated by different baseline scenarios and that the provision of realistic cost-effectiveness results is constrained by limited information on effectiveness and a failure to take into account interaction effects between multiple interventions (e.g., prevention and treatment strategies). They also highlight that the exclusion of cost-effectiveness analysis in studies finding no effect can lead to biased cost-effectiveness estimates. Future research should focus on areas in which evidence is insufficient or unavailable, such as the cost-effectiveness of surveillance, abstinence, school-based education, universal precautions, prevention among HIV-positive individuals, structural interventions and research in particular populations and settings (e.g., vulnerable groups and concentrated epidemics).
