TRAC Plus Center for Treatment and Research on AIDS, Malaria, Tuberculosis and Other Epidemics RWANDAN HIV/AIDS DATA SYNTHESIS PROJECT Final Report 1 PREFACE Public health practitioners frequently must make programmatic decisions with data that are less than perfect. The main reason to use such data is because few well-conducted, high-quality studies exist that can answer an everyday public health question directly, and often we rely instead on imperfect surveillance data to guide our actions. This lack of data has been of concern for the human immunodeficiency virus (HIV) epidemic in Rwanda, where the scale-up of international resources has required rapid responses in planning and targeting prevention and treatment programs. In recent years in Rwanda, there has been a proliferation of HIV surveillance data, including sentinel surveillance in pregnant women, demographic and health surveys, and behavioral surveillance in youth, truck drivers, and sex workers. There also has been an increase in the number of quantitative and qualitative research studies, as well as an accumulation of local and national expertise. Despite this increase in available information, no method for synthesizing the data and no consistent way to analyze or interpret diverse data has been available. In the absence of time and resources to conduct the perfect study to guide programmatic and policy decision making, the important question of how can we use existing data to achieve similar purposes remains. The Center for Treatment and Research on HIV/AIDS, Malaria, Tuberculosis and other epidemics (Trac Plus), in conjunction with the Centers for Disease Control and Prevention––Global AIDS Program (CDC-GAP) Rwanda and with technical assistance from the University of California, San Francisco (UCSF), conducted an HIV data triangulation exercise to answer high priority questions using existing data sources in Rwanda. This exercise, funded by the Presidential Emergency Fund for AIDS Relief (PEPFAR), aimed to better define at-risk populations by geography and risk behavior and to determine the reach and intensity of corresponding programmatic responses. This report describes the steps involved in the triangulation exercise, presents the main findings of the triangulation process, and provides a launching point for next steps, including additional data collection and future research questions to be answered through triangulation. The true success of this exercise has been the integral participation of Rwandans, and we hope that the recommendations in this report will be used to strengthen HIV prevention efforts and improve the quality of life for Rwandan people living with HIV/AIDS. 2 ACKNOWLEDGEMENTS The Coordinating Committee for Data Triangulation and Modes of Transmission would like to thank the following: Trac Plus and CDC-GAP Rwanda for support in planning and conducting the HIV data triangulation exercise in Rwanda.

The methodology of triangulation involves overlapping data on prevalence, risk behaviors, cofactors, and programmatic response for a specific subpopulation or geographic area of concern. Triangulation was applied to data from Rwanda to answer two over-arching questions: What are the differences in HIV prevalence among different population groups over time? What are the potential causes for these differences? Are there gaps in HIV/AIDS programmatic coverage according to prevalence and/or need? The Rwanda Triangulation Project was carried out from December 2007 to September 2008. The project was launched with a stakeholder meeting to identify relevant questions. These questions were prioritized, data sources were identified, and a task force was created. Four months were devoted to compiling and analyzing data. Over 100 independent sources of information on the HIV epidemic in Rwanda were found, including demographic and health surveys, HIV behavioral surveillance data, quantitative and qualitative research studies, and programmatic reports. A final workshop was held in Kigali in September 2008 to conduct training on the methods of triangulation, interpret the data, and make recommendations. Participants at the final triangulation workshop in September 2008 examined a multitude of HIV/AIDS-related indicators at the national, new province, and former province levels to understand epidemic patterns by geography. Data from sentinel surveillance at antenatal clinics (ANCs) were used as the basic gauge of HIV prevalence trends, while the 2005 Demographic and Health Survey (DHS) was used to look at magnitude of HIV prevalence. Using the ANC data, the DHS data, and potentially corroborative data from other sources, participants were charged with identifying regional (new province) epidemic patterns. Participants categorized the epidemic by ―concerning‖ and ―reassuring‖ using the national DHS indicators as a basis for comparison. Data gathered from the Great Lakes Initiative in AIDS (GLIA) show that indicators of risk in Rwanda appear to be substantially lower than those in other GLIA countries, such as Kenya, Tanzania, and Uganda. National data indicate low and apparent decline in HIV prevalence between 2003 and 2005, with a plateau after 2005, based on ANC and DHS HIV prevalence data. Although the HIV epidemic in Rwanda appears stable and declining, there are significant urban-rural differences in ANC prevalence. Urban sites
