It is frequently said that funding is essential to ensure optimal results from a malaria intervention control. However, in recent years, the capacity of the government of Mozambique to sustain the operational cost of indoor residual spraying (IRS) is facing numerous challenges due to restrictions of the Official Development Assistance. The purpose of the study was to estimate the cost of IRS operationalization in two districts of Maputo Province (Matutuíne and Namaacha) in Mozambique. The evidence produced in this study intends to provide decision-makers with insight into where they need to pay close attention in future planning in order to operationalize IRS with the existent budget in the actual context of budget restrictions.
Cost information was collected retrospectively from the provider perspective, and both economic and financial costs were calculated. A "one-way" deterministic sensitivity analysis was performed.
The average economic costs totaled US$117,351.34, with an average economic cost per household sprayed of US$16.35, and an average economic cost per person protected of US$4.09. The average financial cost totaled US$69,174.83, with an average financial cost per household sprayed and per person protected of US$9.84 and US$2.46, respectively. Vehicle, salary, and insecticide costs were the greatest contributors to overall cost in the economic and financial analysis, corresponding to 52%, 17%, and 13% in the economic analysis and 21%, 27%, and 22% in the financial analysis, respectively. The sensitivity analysis was adapted to a range of ± (above and under) 25% change. There was an approximate change of 14% in the average economic cost when vehicle costs were decreased by 25%. In the financial analysis, the average financial cost was lowered by 7% when salary costs were decreased by 25%.
Altogether, the current cost analysis provides an impetus for the consideration of targeted IRS operationalization within the available governmental budget, by using locally-available human resources as spray operators to decrease costs and having IRS rounds be correctly timed to coincide with the build-up of vector populations.
人们常说，资金对于确保疟疾干预控制取得最佳效果至关重要。然而，近年来，由于官方发展援助的限制，莫桑比克政府维持室内残留喷洒（IRS）运营成本的能力面临诸多挑战。本研究的目的是估计莫桑比克马普托省（马图蒂内和纳马查）两个地区实施 IRS 的成本。本研究提供的证据旨在使决策者了解在预算限制的实际情况下，未来规划中需要密切关注的地方，以便在现有预算下实施 IRS。
从提供者的角度回顾性收集成本信息，并计算经济成本和财务成本。进行了“单向”确定性敏感性分析。
平均经济成本为 117351.34 美元，平均每户喷洒成本为 16.35 美元，平均每人保护成本为 4.09 美元。平均财务成本为 69174.83 美元，平均每户喷洒和每人保护的财务成本分别为 9.84 美元和 2.46 美元。车辆、工资和杀虫剂成本是经济和财务分析中总成本的最大贡献者，分别占经济分析的 52%、17%和 13%，以及财务分析的 21%、27%和 22%。敏感性分析适应了±（上下）25%变化范围。当车辆成本降低 25%时，平均经济成本大约变化了 14%。在财务分析中，当工资成本降低 25%时，平均财务成本降低了 7%。
总的来说，目前的成本分析为在现有政府预算内考虑有针对性的 IRS 实施提供了动力，方法是利用当地现有的人力资源作为喷洒操作员来降低成本，并使 IRS 轮次的时间安排正确，与病媒种群的增加相吻合。
