Abstract
Introduction
Malaria is responsible for 50 percent of all preventable absenteeism and leads to a loss of 4 to 10 million school days per year among African school-going children. In Malawi, malaria is a frequent cause of absenteeism in school, resulting in poor scholastic performance among students. Since 2013, Save the Children International (SCI) has been implementing a malaria intervention in primary schools in Traditional Authority (TA) Chikowi, Zomba district. The intervention protocol includes malaria diagnosis using malaria rapid diagnostic tests (mRDTs) and treatment of uncomplicated cases using artemisinin combination therapy (ACT), with all of this carried out by teachers. We conducted a cost-effectiveness analysis of the school-based malaria intervention programme in TA Chikowi in order to determine if the strategy is economically viable.
Methods
The study modelled treatment-seeking behaviour using decision tree modelling, with costs analysed from a societal perspective using the ingredients method. Effectiveness was measured as expected school attendance days and cost-effectiveness was assessed using an incremental cost-effectiveness ratio, with outpatient malaria care as the comparator.
Results
The TA Chikowi intervention strategy is highly cost-effective, with the opportunity cost of teachers' time, antimalarial drugs, and staff costs being the cost drivers. The annual cost of the intervention is US$12.57 (MWK5,781.58) per child, which (for each additional schooling day gained) is US$0.28 (MWK128.81) more than it costs for a health facility to deliver outpatient malaria services in the same time period.
Conclusions
The intervention should be implemented and scaled-up to other areas in the district and is expected to be highly cost-effective in areas with high malaria prevalence.
