Neglected tropical diseases (NTDs) cause significant morbidity and mortality worldwide and impose a large economic burden on endemic countries [1]. In 2006, the United States Agency for International Development (USAID) founded the NTD Control Program to target five NTDs in African, Asian, and Latin American countries, namely, lymphatic filariasis (LF), onchocerciasis, schistosomiasis, soil-transmitted helminthiases (STH), and trachoma; the three targeted STH infections are ascariasis, hookworm, and trichuriasis. The NTD Control Program supported national NTD control and elimination programs' efforts to integrate and scale up delivery of preventive chemotherapy (PC) [2]. PC is the administration of safe, single-dose drugs, either alone or in combination, as a public health intervention against targeted NTDs. Administration is characterized by population-based diagnosis,population-based treatment,and implementation at regular intervals. PC can be delivered as universal chemotherapy (i.e., mass drug administration [MDA]), where the entire population of an area is targeted; targeted chemotherapy, where only high-risk groups (e.g., school age children) are targeted; or selective chemotherapy, where only screened individuals found or suspected to be infected are targeted [3]. Between October 2006 and March 2012, the program provided 589 million NTD treatments through the collaborative efforts of ministries of health, implementing partners, funders, and pharmaceutical donation programs. The implementation of integrated NTD programs at the full national scale remains an important objective in many endemic countries [4]–[8]. Several theoretical frameworks for integration have been proposed; most protocols stress the importance of long-term commitments and concerted efforts of partnerships to realize NTD control and elimination objectives [9]–[14]. However, there is currently a paucity of economic evidence on the costs of integrated PC delivery for NTDs, primarily due to the significant variation in program structures and operations [14]. Given the scarce resources and substantial costs associated with NTD control and elimination, there is therefore a need to accurately determine the cost of program implementation. It is also important to delineate funding commitments to ensure that additional assistance is used to complement available resources, rather than duplicate or replace previous efforts. To allow governments to more easily enumerate costs and funding commitments for NTD control and elimination, the NTD Control Program developed the Tool for Integrated Planning and Costing (TIPAC). The TIPAC, a versatile planning and costing instrument, is designed to be used by members of a NTD program at the national level. For countries with decentralized political structures, the TIPAC can also be implemented at a subnational administrative level. NTD program and financial managers are the primary users of the tool; the involvement of other personnel, including representatives from partner organizations and ministries of education, improves the accuracy and completeness of the TIPAC data. The TIPAC implementation process includes four main phases: Background data collection: country coordinators compile, review, and verify demographic, epidemiologic, and cost classification data. In countries where individual disease control programs are not integrated, this phase may generate fruitful discussions among stakeholders and stimulate collaboration on program planning, outreach, implementation, and monitoring. Data entry: a focal person appointed by the national program enters the planned activity costs. The national strategic plans for NTD control and elimination, also referred to as master plans, serve as the guiding documents for data entry. As the tool is populated, integration opportunities and areas of overlap and duplication are identified. After the costs are entered, stakeholder meetings are convened to identify drug and funding commitments. Finalization and approval: the entered data is reviewed by all stakeholders and approved for use by ministry of health representatives from the national NTD control and elimination program. Results application: the results can be used to inform and guide annual work plans, drug applications, donor coordination efforts, and advocacy and fundraising strategies. The TIPAC is able to convert the information in the tool for use during another funding year, thereby facilitating data entry in subsequent years. The aim of this feasibility study is to assess whether the TIPAC effectively informs and facilitates country program decision-making and the integration of program activities. This study presents excerpts from data collected in two African countries (Sierra Leone, fiscal year [FY] Oct. 2010–Sept. 2011, and Tanzania, FY Oct. 2010–Sept. 2011), one Asian country (Nepal, FY Jul. 2010–Jul. 2011), and one Latin American country (Haiti, FY Oct. 2011–Sept. 2012). The lessons learned from implementing the TIPAC in these four countries can guide the planning and costing of annual NTD control and elimination activities in other NTD-endemic countries.
