Assurance Project (QAP) began to work with federal and regional health authorities in the Russian Federation to apply the improvement collaborative approach to design a model system on HIV/AIDS treatment, care and support in pilot sites in four cities: St. Petersburg (one of 18 districts), Orenburg, Engels, and Togliatti. The aim of the demonstration collaborative was to develop a municipal model for delivery of integrated treatment, care and support services, including tuberculosis (TB) testing and treatment, to persons living with HIV/AIDS (PLWHA). QAP worked with selected organizations in the four regions to develop a system for all HIV-positive patients to be tested for TB, receive Isoniazid preventive therapy (IPT) and, if necessary, be treated for TB. Key partners included local health authorities, infectious disease specialists from AIDS Centers and polyclinics, TB specialists, substance abuse specialists, social service providers, NGOs, and PLWHA.
