Launched in July 2006, more than 19000 patients were seen for complaints of sexually transmitted infections  (STIs) in the first 20 months of the Uganda voucher program.  Marie Stopes International and Microcare Limited have worked closely to build a network of healthcare providers in Ibanda, Isingiro, Kiruhura, and Mbarara districts. Moving beyond the WHO-recommended STI syndromic management used in many developing countries, OBA clinics offer two important improvements: use of low cost lab technologies (wet mount and a microscrope) and a healthcare subsidy for partner referral. A contractual relationship ensures that a financial mechanism is constantly in place to induce compliance with quality lab and management standards.
