To assess the cost-effectiveness of the CARE-SHAKTI harm reduction intervention for injecting drug users (IDUs) over a 3-year period, the impact on the cost-effectiveness of stopping after 3 years and how the cost-effectiveness might vary with baseline human immunodeficiency virus (HIV) prevalence. Design Economic cost data were collected from the study site and combined with impact estimates derived from a dynamic mathematical model. Setting Dhaka, Bangladesh, where the HIV prevalence has remained low despite high-risk sexual and injecting behaviours, and growing HIV epidemics in neighbouring countries. Findings The cost per HIV infection prevented over the first 3 years was US$110.4 (33.1-182.3). The incremental cost-effectiveness of continuing the intervention for a further year, relative to stopping at the end of year 3, is US$97 if behaviour returns to pre-intervention patterns. When baseline IDU HIV prevalence is increased to 40%, the number of HIV infections averted is halved for the 3-year period and the cost per HIV infection prevented doubles to US$228. Conclusions The analysis confirms that harm reduction activities are cost-effective. Early intervention is more cost-effective than delaying activities, although this should not preclude later intervention. Starting harm reduction activities when IDU HIV prevalence reaches as high as 40% is still cost-effective. Continuing harm reduction activities once a project has matured is vital to sustaining its impact and cost-effectiveness.

An assessment of community readiness for HIV/AIDS preventive interventions in rural Bangladesh

Efforts to prevent HIV from becoming widespread among the youth population 15-24 years in Bangladesh are in the early stages. However, conservative religious and cultural norms may curtail the dissemination of needed information about sexuality and condoms. The community-readiness stages model was adopted as a framework for assessing the level of preparedness of community leaders to facilitate planned HIV prevention efforts. Six focus group discussions with three professional groups (teachers, businessmen, drugshop vendors) in Hobiganj district were conducted in late 2005, and a single multi-professional group made up of teachers, imams, and drugshop vendors was convened in early 2007 to assess changes. The audio recordings in Bangla were coded as were English translations. Everyone had heard of AIDS and regarded it as a potential catastrophe for the health, economy and social fabric of Bangladesh. Remarks concerning Stage 1-Vulnerability indicated that most did not believe their community to be at risk, though Bangladesh was. Remarks at Stage 2-Knowledge of Transmission were mostly vague but accurately identified sex, blood and needles as the main means of spread; however sex with sex workers was also mentioned in each group. Remarks at Stage 3-Prevention showed strong opposition to condoms for unmarried males and a preference for current means of forbidding sex outside of marriage. A few in each group recognized the importance of condoms for wayward youth. Stage 4-Planning discussions centered on raising awareness and fear, and a desire for government and media to take the lead. By 2007 participants articulated more realistic strategies that they themselves could, and had, implemented, but also raised barriers that authorities should help them overcome. The findings provide formative information on the constraints and opportunities of community groups as partners in HIV preventive interventions and strategies to help them move to a higher stage of readiness.

Young clients of hotel-based sex workers in Bangladesh: vulnerability to HIV, risk perceptions, and expressed needs for interventions

A qualitative study was conducted among key informants and 53 young clients (15 to 24 years of age) of commercial sex workers from nine hotels in Dhaka, Bangladesh. Respondents reported first sexual encounter before 18 years of age, and reasons for purchasing sex were to prove masculinity or to reduce wet dreams and masturbation, thought to be detrimental to health. Limited knowledge of HIV and sexually transmitted infections was linked to high-risk sexual practices. Condom use was related to perceptions of cleanliness, status, and trust in the sex worker. A hotel-based, confidential intervention program promoting safe sex practices among clients of sex workers is warranted.
