[Management of malaria in Benin: evaluation of the practices of healthcare professionals following the introduction of artemisinin derivatives].

In 2004 the policy for malaria management in Benin changed when the National Malaria Coordination Program (NMCP) introduced artemisinin-based combination therapy (ACT) for treatment of uncomplicated malaria. Up to that time, chloroquine had been used for first-line therapy against uncomplicated malaria and sulfadoxine pyrimethamine had been used in case of failure. Artemisinin derivatives have been used for monotherapy in Benin since 2002. The purpose of this transverse study carried out among public and private centers in Cotonou from March 16 to May 17, 2005 was to determine the impact of the switch to ACT on the practices of healthcare professionals. Medical centers were randomly selected from each stratum after identification and stratification of all facilities in the healthcare pyramid. A survey questionnaire was sent to healthcare workers. A total of 690 health workers responded to the questionnaire. Most responders (95.5%) were familiar with artemisinin but a lower percentage (89.6%) prescribed them. Responders were less knowledgable about ACT drugs and Coartem was the best known combination in the minds of prescribers. Biological diagnosis was available for 50% of patients. Artemisinine (derivates) were mainly prescribed as a second choice treatment and as monotherapy whether for severe or uncomplicated malaria. They were prescribed to pregnant women in 34.6% of the cases. Dosage was incorrect in 26.1% of cases in adults and 20.9% of cases in children. These findings indicate that more effort is needed to inform healthcare workers. This is especially urgent since the country is now considering revising its malaria management policy to make ACT available at all levels of the healthcare system. An effective information campaign must be set up to ensure that health workers and drug retailers throughout the country are duly informed of the new malaria treatment policy.
