Introduction
The World Health Organization (WHO) estimates worldwide were 228 million cases of malaria and 405,000 deaths in 2018 as compared to 219 million cases including 435,000 deaths in 2017. Most malaria cases occur in sub-Saharan Africa in children under fiveyears-old and pregnant women [1]. In Mali, malaria remains a major endemic and leading cause of morbidity and mortality in health centers [2]. Despite the decreasing burden of malaria in our country through extensive success of the National Malaria Eradication Program (NMEP), the national health statistics show that malaria is still rang first among all diseases; It represents 39% of all outpatient visits in the health center and affects 19% of children under five-years-old [2]. Chloroquine (CQ) was massively produced in 1945. It provided a low toxicity and it was the least expensive and the most effective treatment of malaria. It was used to treat uncomplicated malaria or in the chemoprophylaxis. Chemoprophylaxis was one of the two pil-early antimalarial drug treatment for confirmed malaria cases. Treatment should be in respect with the current standards and guidelines to reduce morbidity. The success of these recommendations in the new treatment policy will depend on the adherence and compliance of healthcare professionals and their patients [15]. No data were available on this protocol and its perception by prescribers. Consequently, we conducted this study to assess the conformity to the standards and guidelines of the NMCP of prescribed antimalarial drugs in Mali.

Methods
Our study took place in the health centers of Kangaba and Bougouni, two malaria endemic areas. Kangaba is located 80 km southwest of Bamako where the population is predominantly Malinké, while Bougouni is located 120 km south of Bamako where the population is predominantly Bambara and Senoufo. We conducted a cross-sectional study during malaria transmission season from July to December 2019. The sampling consisted of all prescriptions with at least one antimalarial drug and recorded in a pharmacy registry. The nature of the antimalarial drugs, its dosage, the duration of treatment and the type of prescribed antimalarial combination were analyzed based on the NMCP guidelines [14]. A non-compliant prescription was defined as any breach of one or more of the parameters listed above with respect to the NMCP guidelines. In the registries, we also collected information about biological diagnosis and the socio-demographic characteristics (age and sex of the patient). In addition, a report form was administered to all prescribers Data focusing on their professional qualification and their level of knowledge of the malaria treatment protocol. lars of the malaria eradication campaign in the 1950s and in the 1970s [3]. The first cases of chloroquine-resistance were reported in the world between 1957 and 1960 [4][5][6][7].
The resistance to antimalarial drugs is a serious hurdle for malaria control in endemic countries [8]. P. falciparum developed resistance to low-cost and well-tolerated antimalarial drugs such as chloroquine, amodiaquine (AQ), antifolates, and mefloquine (MQ) [3][4][5][6]. This has led the WHO and the National Malaria Control Programs (NMCP) to recommend the artemisinin-based combination therapy (ACT) for malaria treatment [9]. Nowadays, first signs of the emergence of parasites resistant to artemisinin derivatives drug have been reported in Southeast Asia [10,11], but in Africa where ACTs are still very effective [12,13]. However, sub-Saharan Africa remains under threat due to the widespread use of ACTs along the increasing intercontinental human migrations. In addition, the circulation of sub-standard or counterfeit antimalarial drugs coupled to the non-adherence of patients to treatment may contribute to rapid selection of drug resistant malaria parasites. In 2006, the Malian NMCP adopted the artemisinin-based combination therapy (ACT) as the first-line treatment for uncomplicated malaria. In Mali, artemether-lumefantrine (AL) and amodiaquine-artesunate (AQ-AS) are used to treat uncomplicated malaria and the artesunate, artemether or quinine are used to treat severe malaria cases by intra-venous route.
The Malian NMCP has set up a strategic plan and developed guidelines with a protocol for the management of uncompleted and severe malaria cases [14]. The prescriber's responsibility is to institute correctly an   (Table 3). Among the interviewees, 53% in Kangaba and 60% in Bougouni did not have sufficient knowledge of the existence of malaria treatment protocol according to the NMCP guidelines (Table 3).

Discussion
We conducted a cross-sectional study to evaluate the application of the national protocol for the management of uncomplicated malaria in Kangaba and Bougouni. This study took place from July to December 2019. We interviewed 45 healthcare professionals including nine (9) doctors, 26 nurses, 10 midwives and 300 children treated for malaria (210 cases in Kangaba Types, dosages and duration of treatment combination prescribed by the NMCP are shown below (Table 1  and Table 2).

Statistical analysis
Data were collected on a report form, entered into Excel and analyzed using the statistical software Epi info 6.04.

Results
We recorded 300 prescriptions with at least one antimalarial drug (70% in Kangaba and 30% in Bougouni) ( Table 3). Non-compliant prescriptions represented 67.1% in Kangaba and 53.3% in Bougouni. Dosages were non-compliant in Kangaba (10.1%) and in Bougouni (26.2%). All the prescriptions in Kangaba were fully compliant with the duration of treatment and only 2.4% in Bougouni were not. Among all the recommended ACTs, artemether-lumefantrine was the most prescribed with 100% in Kangaba and 97.6% in Bougouni (Table 4). Prescriptions were made when the diagnostic of malaria firmation of malaria before the treatment [19][20][21]. Confirmation by biology is one of Interventions to control malaria have been scaled up in recent years including the deployment RDTs to improve malaria surveillance and to guide malaria treatment in health facilities. The confirmation of parasite infection in a lab is important in the management of malaria and other febrile illnesses. It is necessary for clinicians to accurately know the actual infection status of each patient in order to manage properly febrile illnesses. As RDTs may be the only available tool for very remote areas, the issue of clinicians trusting the results is paramount if confirmation of parasite infection has to remain the basis for prescribing an anti-malarial drug.
Currently, ACT is the best choice to treat uncomplicated malaria cases. The efficacy and safety demonstrated of ASAQ and AL have led the WHO and the Malian NMCP to recommend these compounds for uncomplicated malaria treatment [22][23][24]. In this study, the recommended ACTs were prescribed only in 46.7% of cases in Bougouni and 32.9% in Kangaba. The prescription was not conform in 53.3% in Bougouni and 67.1% in Kangaba. A. Soumana, et al. in 2016 in Niamey reported that the antimalarial drugs prescription was not conform in 29.3% of patients [20]. Among the ACTs prescribed in Bougouni, 45.6% were AL combination versus 1.1% of ASAQ combination. All the ACTs prescribed in Kangaba were the artemether-lumefantrine combination. The non-prescription of amodiaquine-artesunate combination could be explained by the refusal of patients to take this drug due to the adverse effects of amodiaquine. and 90 cases in Bougouni). This study provided the baseline information that can be used by the NMCP to plan its upcoming activities. Female patients were the most represented in Kangaba (52.9%) and Bougouni (56.7%). The most affected age group was patients aged 13 years old and older with in Kangaba (61.9%) and in Bougouni (61.1%) ( Table 3). This result could be explained by the seasonal chemoprevention and the free management of malaria cases in children aged five years or younger, which would probably reduce the number of malaria episodes in this age group.
Prescribers were unaware of the national protocol for management malaria cases based on the NMCP in Bougouni (60%) and in Kangaba (53%). These proportions were higher as compared to about one third reported by Ahmed, et al. in Sudan in 2004 [16] and 15.5% reported by Minzi in Tanzania in 2008 [17]. In Burkina Faso, LT. Ouédraogo, et al. in 2012 reported that prescribers affirmed to know the new treatment protocol for uncomplicated malaria in 84.6% [18]. This lack of knowledge of certain prescribers could be explained by the insufficiency or lack of training of health workers on the new national protocol. Indeed, the WHO and the Malian NMCP have recommended a biological confirmation of malaria cases using either the RDT or microscopy (thick blood smear) before any treatment is initiated. Most treated malaria cases were confirmed biologically in Bougouni (87.8%) and Kangaba (83.3%). In contrast, A. Soumana, et al. in    If ACTs were used as the first-line treatment for uncomplicated malaria in Bougouni in 46.7%, in contrast injectable Artemether was used in 48.1%in Kangaba. Rakotoarivelo R.A, et al. in 2012 in Madagascar reported that quinine was used as the first line treatment for uncomplicated malaria treatment instead of ACT [25]. Many reasons could explain this practice, such as vomiting or nausea or refusal to take the tablets (especially in children). These observations showed that the prescription of antimalarial drugs required a certain knowledge of the patient health and the healthcare setting. The use of injectable artemisinin in monotherapy for uncomplicated malaria treatment could be a factor for promoting the emergence and spread of resistance to artemisinin and its derivatives. In our study, 12.7% of patients were treated with an incorrect dosage of ACT. Patients were treated with ACTs with a non-compliant dosage in Bougouni (22%) and (7.2%) in Kangaba. Two patients had a Treatment duration was conform in all patients except two in Bougouni. Sow, et al. in 2016 in Guinea Conakry reported that 18.1% of patients received treatment for more than three (3) days and 39.8% received incorrect dosages [26].
Incomplete malaria treatment does not maintain an adequate antimalarial drug plasma level over a long enough time to eliminate all parasites in an individual. Thus, the selection of antimalarial drug-resistant parasites is promoted. The dosage was non-compliant for the management of uncomplicated malaria in Mali. This could be explained by the lack of training of agents on the national protocol and the lack of qualification of some prescribers. Hence, we emphasized the continuing training of prescribers at all levels of the health pyramid. This observation must challenge the NMCP and the Ministry of Health and Public Hygiene to implicate more the prescribers upstream for a large dissemination of the national guidelines for the management of malaria.

Conclusion
Our study showed a low utilization of the new protocol resulting in prescriptions that may be detrimental to patients. Proper use of ACTs is imperative to ensure their efficacy and to delay the emergence of drug resistance. We therefore suggest a large dissemination of the new malaria treatment protocol, and a continuing training on the the NMCP guidelines.
