The expansion of malaria prevention and control to school-aged children is receiving increasing attention, but there are still limited data on the costs of intervention. This paper analyses the costs of a comprehensive school-based intervention strategy, delivered by teachers, that included participatory malaria educational activities, distribution of long lasting insecticide-treated nets (LLIN), and Intermittent Parasite Clearance in schools (IPCs) in southern Mali.
Costs were collected alongside a randomised controlled trial conducted in 80 primary schools in Sikasso Region in Mali in 2010-2012. Cost data were compiled between November 2011 and March 2012 for the 40 intervention schools (6413 children). A provider perspective was adopted. Using an ingredients approach, costs were classified by cost category and by activity. Total costs and cost per child were estimated for the actual intervention, as well as for a simpler version of the programme more suited for scale-up by the government. Univariate sensitivity analysis was performed.
The economic cost of the comprehensive intervention was estimated to $10.38 per child (financial cost $8.41) with malaria education, LLIN distribution and IPCs costing $2.13 (20.5%), $5.53 (53.3%) and $2.72 (26.2%) per child respectively. Human resources were found to be the key cost driver, and training costs were the greatest contributor to overall programme costs. Sensitivity analysis showed that an adapted intervention delivering one LLIN instead of two would lower the economic cost to $8.66 per child; and that excluding LLIN distribution in schools altogether, for example in settings where malaria control already includes universal distribution of LLINs at community-level, would reduce costs to $4.89 per child.
A comprehensive school-based control strategy may be a feasible and affordable way to address the burden of malaria among schoolchildren in the Sahel.
疟疾预防与控制工作向学龄儿童的扩展正受到越来越多的关注,但关于干预成本的数据仍然有限。本文分析了一项由教师实施的综合性校本干预策略的成本,该策略包括参与式疟疾教育活动、长效驱虫蚊帐(LLIN)的发放以及马里南部学校的间歇性寄生虫清除(IPC)措施。
成本数据是在2010 - 2012年于马里锡卡索地区的80所小学开展的一项随机对照试验过程中收集的。2011年11月至2012年3月期间收集了40所干预学校(6413名儿童)的成本数据。采用提供者视角。运用成分法,成本按成本类别和活动进行分类。估算了实际干预措施以及更适合政府扩大规模实施的简化版方案的总成本和每名儿童的成本。进行了单变量敏感性分析。
综合干预的经济成本估计为每名儿童10.38美元(财务成本8.41美元),其中疟疾教育、LLIN发放和IPC措施分别为每名儿童2.13美元(20.5%)、5.53美元(53.3%)和2.72美元(26.2%)。人力资源是关键的成本驱动因素,培训成本是总体项目成本的最大贡献者。敏感性分析表明,改为发放一顶而非两顶LLIN的调整后干预措施会将经济成本降至每名儿童8.66美元;而例如在疟疾控制已包括在社区层面普遍发放LLIN的环境中,完全排除学校内的LLIN发放,会将成本降至每名儿童4.89美元。
综合性校本控制策略可能是应对萨赫勒地区学童疟疾负担的一种可行且经济实惠的方式。
