Community action for preventing HIV in Cambodia: evaluation of a 3-year project.

摘要

The 'Community Action for Preventing HIV/AIDS Project' was implemented in four provinces in Cambodia (2001-04) to support a comprehensive set of HIV prevention efforts. Implementation was strictly monitored in terms of inputs, outputs and outcomes. We examine changes in these variables during the project period to assess the extent to which they were related to the project. Inputs and outputs were monitored regularly by supervision and quarterly project reports. Baseline and follow-up surveys were conducted on 10 target groups to measure changes in outcome indicators related to sexual risk behaviours, uses of HIV voluntary counselling and testing (VCT), self-reported sexually transmitted infections (STIs) and other indicators. The analyses use data from surveys and from project monitoring. Spending on HIV-related work at provincial level increased markedly, including investments in VCT, STI facilities and staff training. Yearly expenditure increased about 7-fold compared with years immediately preceding the project. VCT centres increased from 3 to 12, numbers of counsellors from 10 to 27, and numbers of client visits more than doubled. STI laboratory facilities increased from 0 to 6 with coverage of STI check-ups among sex workers increasing from 70% to 93% and a decline in men attending STI clinics. The survey results indicate significant changes in a number of major outcome indicators such as consistent condom use related to sex work (80%), HIV testing and counselling after HIV tests, especially among police (42 to 72%, P 0.001) and brothel-based sex workers (48 to 89%, P 0.001). Self-reported STIs declined in most groups. Finally, the programmatic systems for planning, managing and monitoring implementation of activities at both central and provincial level, as well as technical guidelines, developed under the project have become the standard for the national programme. In conclusion, the project appears to have been comprehensive and a number of favourable changes in output and outcome indicators occurred. It seems likely that the project made a substantial contribution to these positive outcomes, though the extent is not clear. The project is likely to have powerful long-term effects through strengthening of capacity and establishment of systems for the national programme.
