Malaria Case Management and Treatment Adherence
Summary
Effective management of malaria hinges on timely diagnosis, appropriate antimalarial therapy and sustained treatment adherence to prevent progression to severe disease and limit transmission. Case management encompasses the identification of suspected malaria through clinical assessment and confirmation by parasitological tests, notably rapid diagnostic tests (RDTs) or microscopy. Once confirmed, artemisinin-based combination therapies (ACTs) form the cornerstone of treatment for uncomplicated Plasmodium falciparum malaria, while injectable artesunate is recommended for severe cases, often preceded by pre-referral doses in remote settings. Adherence to the full course of therapy is essential to achieve parasitological clearance, reduce the risk of recrudescence and forestall the emergence of drug resistance. Health system factors—such as availability of diagnostics and drugs, provider training, supervision and patient counselling—directly influence adherence to national guidelines. Patient-level determinants, including understanding of dosing schedules, perceived side-effects and socio-economic barriers, further shape treatment completion. Strengthening the interface between health services and communities remains critical for improving outcomes and sustaining the global malaria control agenda.
Research from Nature Portfolio
Recent work has applied a within-host modelling framework to quantify the impact of imperfect adherence to artemether-lumefantrine therapy on clinical outcomes. By integrating pharmacokinetic and pharmacodynamic parameters with immune response dynamics, the model predicts that suboptimal adherence nearly doubles the rate of treatment failure, with the greatest adverse effects in young children. These insights underscore the importance of rigorous adherence support and monitoring in routine care settings, and highlight the value of mechanistic models in informing strategies to optimise drug dosing and deployment.
Malaria Case Management and Treatment Adherence publication trend
The graph below shows the total number of articles in malaria case management and treatment adherence across all publications each year (not limited to Nature Index journals).
Technical terms
Artemisinin-based combination therapy (ACT): A treatment regimen combining an artemisinin derivative with a partner drug to improve efficacy and prevent resistance.
Rapid diagnostic test (RDT): A lateral-flow immunochromatographic assay that detects malaria antigens in a finger-prick blood sample.
Treatment adherence: The extent to which patients complete drug regimens exactly as prescribed, including dose, timing and duration.
Within-host modelling: A mathematical approach that simulates the interaction of drug kinetics, parasite biology and host immunity to predict treatment outcomes.
Pre-referral treatment: An initial dose of antimalarial medication administered to suspected severe malaria cases before transfer to a higher-level facility.
