Antimalarial drug prescribing by healthcare workers when malaria testing is negative: a qualitative study in Madagascar

BACKGROUND: Despite the World Health Organization and the National Malaria Program of Madagascar recommending that antimalarial drugs only be prescribed for patients with positive results on malaria rapid diagnostic tests, healthcare workers continue to prescribe these drugs for cases with negative test results. We explored why and how primary healthcare workers in Madagascar continue to prescribe antimalarial drugs despite this guidance. METHODS: We purposively selected 14 medical doctors and 2 nurses from 11 primary health facilities (6 public, 5 private) in Toliara, Madagascar, and interviewed them regarding their antimalarial prescribing behaviors. Semi-structured interviews were conducted, focusing on why and how antimalarials were prescribed for clients with negative rapid diagnostic test results. Interviews were audio-recorded and transcribed verbatim, and the responses were manually coded until consistent themes emerged. RESULTS: The narrative of healthcare workers regarding their continued prescribing of antimalarials despite negative test results revealed the following: (1) they prescribe antimalarials without positive test results due to their faith to give top priority to clients including the ethical value of beneficence, hope to maintain clinician’s independence, and belief in drug effectiveness; (2) they use antimalarials despite negative test results due to the availability of alternative ways to procure antimalarials; and (3) they carefully select cases to prescribe and determine specific antimalarials despite negative test results by considering the client’s physical condition, preference, and economic status. Our results indicate that healthcare workers prioritized clinician autonomy to give the best care they believed for each client they received, which led to conflict with policy administrators that urged clinicians to follow the national policy and guidelines. Moreover, healthcare workers had access to multiple sources of antimalarial drugs, and there was a lack of consistency in the program provisions that allowed alternative routes for prescribing outside of official policy. CONCLUSIONS: We have shown how a national malarial treatment policy was translated into practice in Madagascar and have highlighted the barriers that may prevent policy success. We must attend to each of these barriers if we are to promote optimal use of antimalarial drugs.
