Health providers trained to perform malaria rapid diagnostic tests (RDT) are still prescribing valuable malaria medicines to patients who do not have malaria, according to new research published in PLOS ONE.

Almost 5,000 participants from 40 communities took part in the study, at a variety of public health facilities, pharmacies and drug stores in the Nigerian state of Enugu. Despite the three different training interventions that they received and their satisfaction with the courses and materials, rates of RDT use remained less than 50%.

The researchers from the Artemisinin-based Combination Therapy (ACT) Consortium at the University of Nigeria and the London School of Hygiene & Tropical Medicine in the UK split the health workers into three groups, to either receive a comprehensive RDT training or the same training plus a health campaign in schools, while the control arm received basic instructions to use RDTs. The first group had the highest rate of testing (48%), especially in public health facilities.

Prof. Obinna Onwujekwe from the University of Nigeria, lead author of the study, said: “This study confirms that treating malaria based on signs and symptoms alone remains an ingrained behaviour that is difficult to change. If governments want RDTs to effectively target the use of ACTs and avoid their misuse, then they must be supported by varieties of intensive and sustained interventions aimed at changing the behaviour of health providers and the expectations of patients and their families.”
