Application of loop analysis for evaluation of malaria control interventions

摘要: Despite continuous efforts and recent rapid expansion in the financing implementation of malaria control interventions, still remains one most devastating global health issues. Even countries that have been successful reducing incidence malaria, is becoming more challenging because changing epidemiology waning community participation interventions. In order to improve effectiveness interventions promote understanding necessity continued efforts, there an urgent need develop new methodologies examine mechanisms by which community-based could reduce local incidence. This study demonstrated how impact on can be examined complex systems qualitative analysis combined with extensive review literature. First, sign digraphs were developed through loop analyse seven interventions: source reduction, insecticide/larvicide use, biological control, treatment anti-malarials, insecticide-treated mosquito net/long-lasting insecticidal net, non-chemical personal protection measures, educational intervention. Then, for each intervention, literature a variety pathways intervention influence as well interactions between variables involved system. Through it possible see whether increases variable qualitatively or decreases other leaves them unchanged net effect multiple, interacting variables. Qualitative analysis, specifically useful tool Without relying numerical data, was able describe basis patterns systems. methodology generalizable various disease at different levels, utilized stakeholders such researchers, leaders policy makers better plan evaluate their
