“…In many settings where RDTs have been introduced, the tests have been underused and the overuse of antimalarial drugs has remained high. Even when tests are carried out, findings are accumulating from studies in different countries that show between 35 and 85% of RDT negative patients have been prescribed antimalarials Bisoffi et al, 2009;Chinkhumba et al, 2010;Elmardi et al, 2009;Hamer et al, 2007;Kyabayinze et al, 2010;Reyburn et al, 2007;Skarbinski et al, 2009). By contrast, other studies have found a reduction in overdiagnosis, down to between 4% and 16% RDT negative patients receiving antimalarials after the introduction of RDTs with various supporting interventions (Bastiaens et al, 2011;D'Acremont et al, 2009;Hopkins, 2008;Masanja et al, 2010;Mawili-Mboumba et al, 2009;Msellem et al, 2009;Thiam et al, 2011;Williams et al, 2008).…”
