The public health value of a vector control tool depends on its epidemiological efficacy, but also on its ease of implementation. This study describes an intensive distribution scheme of a topical repellent implemented in and for the purpose of a cluster-randomized trial using the existing public health system.
The trial aimed to assess the effectiveness of repellents in addition to long-lasting insecticidal nets LLIN and occurred in a province of Cambodia. Determinants for accessibility and consumption of this tool were explored. A 2-weekly bottle exchange programme was organized. Distributors recorded information regarding the amount of bottles exchanged, repellent leftover, and reasons for not complying in household data sheets. Distributor-household contact rates and average 2-weekly consumption of repellent were calculated.
Household and distributors characteristics were obtained using questionnaires, surveying 50 households per cluster and all distributors. Regression models were used to explore associations between contact and consumption rates and determinants such as socio-economic status. Operational costs for repellent and net distribution were obtained from the MalaResT project and the provincial health department. Contact rates were found to associate with district, commune and knowing the distributor, while consumption was associated with district and household head occupation.
After the existing public health system was reinforced with programmatic and logistic support, an intense 2-weekly distribution scheme of a vector control tool over a 2-year period was operated successfully in the field.
