Management of Malaria in Pregnant Women at the Maternity Unit of the University Teaching Hospital Yalgado Ouedraogo (UTH-YO) in Ouagadougou: About Report on the Quality of Care ()
1. Introduction
Malaria is an endemo-epidemic, tropical and intertropical parasitic disease caused by hematozoans of the genus Plasmodium, transmitted by mosquitoes of the genus Anopheles [1] . According to the World Health Organization (WHO), there are approximately 10,000 maternal deaths related to this pandemic each year [2] . In Burkina Faso, it is said to be the main reason for consultations, hospitalization and deaths in health facilities. Indeed, in 2013, malaria accounted for 46.5% of the reasons for consultation, 61.5% of hospitalizations and 30.5% of deaths affecting the entire population [3] .
To provide an effective response to this pandemic in pregnant women, WHO recommends as priority interventions the effective management of confirmed cases and the adoption of preventive measures, including [4] :
・ the use of long-lasting insecticidal nets (LLINs),
・ intermittent preventive treatment (IPT),
・ rapid diagnosis based on the search for plasmodies either by a thick drop or by a rapid diagnostic test (RDT).
Despite the adoption of these measures at the national level, there is no denying the persistence of morbidity and mortality due to malaria infection [5] . Also, through this study we propose to do a report on the quality on the management of the pandemic at the maternity of Yalgado Ouédraogo University Teaching Hospital (UTH-YO) which is the largest gynecological and obstetrical reference structure in Burkina Faso.
2. Patients and Method
This was a descriptive cross-sectional study conducted from July 29 to October 02, 2016, a period of 3 months. The study was conducted in the Department of Gynecology and Obstetrics of Yalgado Ouedraogo University Teaching Hospital (UTH-YO), recognized as a reference structure for regional hospitals and medical centers with surgical antenna of the city of Ouagadougou. This structure serves as a training framework for doctors in specialization, medical and pharmaceutical students, senior health technicians at the University of Ouagadougou and students at the National School of Public Health (NSPH) and some private schools. It is equipped with 95 hospital beds. The sampling was opportunistic for all the patients and care givers. Our study had 2 targets:
・ as main targets, all pregnant women admitted for inpatient management who have consented to participate in the study,
・ as secondary targets, all service care providers who agreed to participate in the study. These providers included doctors, medical students, and midwives.
Data collection used 3 techniques:
・ Rapid Diagnostic Test (RDT): A capillary blood sample from 5 μl using a calibrated loop was used to perform the SD Bioline Malaria Antigen Pf test. This is a test for the detection of Plasmodium falciparum HRP2 antigen based on immunochromatography on a strip [4] .
・ Direct observation of patients and resources available in the department.
・ Semi-structured individual interviews with patients and care providers.
After the RDT was performed, each patient was subjected to an individual questionnaire which was completed using the prenatal consultation logbook as well as the patient’s record and direct observation of the patient. The data was coded and captured on a microcomputer. The cleaning and analysis was carried out using Epi info software version 7.
3. Results
3.1. Malaria Prevalence
Of the 351 patients screened, 310 (88.3%) tested negative and 41 tested positive for RDT. The prevalence of malaria was therefore 11.7 per cent.
3.2. Characteristics of the Sample Studied
The average age of the patients was 26.8 ± 6 years [13 - 45]. They lived in union in 315 cases (89.7%) and alone in 36 cases (10.3%). In our study population, 67.6% were educated. Unemployed patients numbered 218 (62.1%). They were in the third trimester of their pregnancy in 293 cases (84%), in the second trimester in 47 cases (13.39%), in the first trimester in 11 cases (3%).
There were 44 care givers. Their average age was 33.25 ± 6.46 years with extremes ranging from 26 to 55 years. The average years of service was 7.77 ± 5.02 years with extremes ranging from 1 to 30 years. There were 24 men (54.55%) and 20 women (45.45%).
3.3. Providers’ Knowledge of the Signs of Malaria
3.3.1. Simple Malaria
The distribution of the care providers’ knowledge according to their responses on signs of simple malaria was presented in Table 1.
3.3.2. Severe Malaria
The distribution of the care providers’ knowledge according to their responses on clinical signs of severe malaria was presented in Table 2.
Table 1. Distribution of care providers’ knowledge according to their responses on signs of simple malaria.
Table 2. Distribution of care providers’ knowledge according to their responses on clinical signs of severe malaria.
3.3.3. Biological Signs of Severe Malaria
The distribution of providers’ knowledge according to responses on biological signs of severe malaria has been presented in Table 3.
Anemia (hemoglobin < 5 g/dl) was cited by all providers as the primary biological sign of severe malaria.
3.4. Providers’ Knowledge of Malaria Prevention Measures
All providers interviewed stated that the use of LLIN and IPT were the primary means of preventing malaria during pregnancy. In addition, they all said that every pregnant woman should sleep under LLIN from the diagnosis of pregnancy until delivery. Sanitation of the living environment as another means of prevention was cited by 06 providers (13.6%) and for 4 (9.1%), it was the use of mosquito repellent creams. With regard to taking IPT, 43% or 97.72% of providers said that the first dose should be administered in the second trimester and the second in the third trimester, and for 0.1% or 2.27%, taking should begin as soon as the pregnancy is diagnosed.
Table 3. Distribution of care providers’ knowledge according to their responses on biological signs of severe malaria.
3.5. Providers’ Knowledge of Curative Treatment of Malaria
3.5.1. Simple Malaria
A total of 34 providers, or 77.3% of the providers, stated that quinine was the reference molecule for treatment in pregnant women. For 37% or 84.1% of providers, the Artemisinin-based Combination treatment (ACT) could be used in pregnant women after the 16th week of amenorrhea. This figure nevertheless indicates how this disease continues to weigh heavily on the health of the population of Burkina Faso.
3.5.2. Severe Malaria
For the treatment of severe malaria, 37% or 84.1% said that artemether injection was the most recommended form. For 0.4% or 9.1% it was injectable artesunate and for 3% or 6.8% it was injectable quinine. Regarding the dosage of the molecules, 30 providers, 81.1%, gave a correct dosage for artemether injection, 75% for artesunate injection and 100% for quinine injection.
3.6. Availability of Means of Malaria Management for Pregnant Women in the Ward
During our investigation, at the gynecology and obstetrics department’s drug depot, we observed the absence of IPT, LLIN, and RDT. Only one molecule was available. It was quinine in its injectable form (400 mg) and in its compressed form (300 mg).
3.7. Pregnant Women’s Knowledge about Malaria Prevention
They relate to the use of the LLIN, TPI, environmental sanitation and the use of mosquito repellent creams. The distribution of patients according to their knowledge of prevention methods was presented in Table 4.
4. Discussion
4.1. Prevalence of Malaria Infection
The prevalence of malaria infection in the study sample was 11.7%. Yakpa [6] reported a 35.9% higher prevalence of malaria infection in pregnant women in her study at Lomé University Hospital. During our investigation, the analysis of the information contained in the health record allowed us to know that some patients had received antimalarial treatment in the weeks preceding their admission to the service. This could have had an impact on the prevalence of infection.

4.2. Providers’ Knowledge of Clinical Signs of Malaria
In the providers’ assessment of knowledge of the clinical signs of simple malaria, fever was cited by 95.5% of providers, headache by 90.9%, vomiting by 84.1%, chills by 72.7%, soreness by 68.2% and asthenia by 61.4%. Feller-Danssokho and al [7] in Senegal also reported similar results.
The National Malaria Control Program (NMCP) defines simple malaria as a fever (axillary temperature greater than or equal to 37.5˚C) or a history of a warm body in the last 72 hours and the detection of plasmodium in the blood by a positive rapid diagnostic test (RDT) [8] . Unfortunately, we found no RDT in the service depository. In this context, providers used the syndromic approach in the diagnosis of simple malaria. This implies from the outset a risk of overdiagnostic error with the consequence that antimalarial drugs are misused, which would encourage possible resistance of plasmodium to the molecules used. In addition, the syndromic approach could prolong the patient’s hospital stay for other causes of fever. It would therefore be essential to make RDTs available at the maternity ward so that providers can confirm all malaria cases before malaria treatment is started.
For severe malaria, providers were also familiar with clinical signs. Frankish jaundice was cited by 97.7% of providers, prostration by 79.5%, repeated convulsions by 65.9%, respiratory distress by 40.9% and acute pulmonary edema by 47.7%. Our results were close to those of Ndiaye [9] in Senegal and Doudou [10] in Côte d’Ivoire. Knowledge of the signs of malaria severity helps to improve patient care [11] .
4.3. Providers’ Knowledge of Malaria Prevention
In our series, all providers had a good knowledge of how to prevent malaria during pregnancy. Indeed, they all stated that the use of LLIN and the use of IPT were the primary means of prevention recommended by the NMCP. In addition, they all agreed that every pregnant woman should sleep on LLIN from the diagnosis of pregnancy until delivery. Sanitation of the living environment as another means of prevention was cited by 13.64% of providers and for 9.1%, it was the use of mosquito repellent creams. This satisfactory level of providers’ knowledge of prevention could be explained by the multitude of training and guidelines received on the subject.
Regarding IPT use, 97.7% of providers said that the first dose should be given in the second trimester and the second in the third trimester and 2.2% said that it should start as soon as the pregnancy is diagnosed. The NMCP recommends that IPT begin in the second trimester of pregnancy and consists of three tablets taken orally each month until delivery with a minimum interval of one month between doses [8] . Regular training targeting the staff of referral centres on the protocol of preventive treatment of malaria in pregnant women is necessary to harmonize knowledge on this very important aspect of management.
4.4. Providers’ Knowledge of the Treatment of Simple Malaria
More than three quarters (77.27%) of the providers surveyed said that quinine was the reference molecule for treatment in pregnant women. For 84.09%, ACTs could be used after the 16th week of amenorrhea. In the study by Monbrison and al [12] in 2008, 68.2% and 78.2% of the providers interviewed had recommended quinine and ACTs respectively for the treatment of malaria after the appearance of active fetal movements. Our results could be explained on the one hand by a good dissemination of national guidelines for the treatment of simple malaria and on the other hand, by the existence of a therapeutic protocol in the service. However, 15.91% of claimants surveyed.
4.5. Knowledge about the Treatment of Severe Malaria
Our study revealed that artemether injection was cited by 84.1% of providers, then artesunate injection by 9.1% and finally quinine injection by 6.82% as molecules used for the treatment of severe malaria. This reflects a satisfactory level of knowledge among providers about the treatment of severe malaria. In the national protocol, artesunate injection should be used first-line, then artemether injection and finally quinine injection. The first-line use of artesunate has the advantage of being used intramuscularly and intravenously depending on the urgency. This molecule induces fewer side effects compared to artemether. The latter should be administered exclusively intramuscularly [8] [13] .
5. Conclusion
Providers’ and patients’ knowledge of malaria in the obstetrics and gynecology department is quite satisfactory. However, some shortcomings were noted in the provision of screening and curative and preventive treatment. The elimination of malaria in our country will require joint efforts at all levels.
