Maternal Mortality in the Gynecology-Obstetric Department at the Yalgado Ouedraogo University Hospital Center (CHUYO), Burkina Faso: About 181 Cases Collected from January 1st to December 31st 2016

Objective: To study maternal mortality in the obstetrics and 
gynecology department at Yalgado Ouedraogo teaching Hospital 
Center. Patients and Methods: We conducted a cross-sectional retrospective and descriptive study of 
181 cases of maternal deaths during study period. The parameters studied were 
sociodemographic characteristics, the causes of death, the clinical data and 
the contributing factors. Results: The maternal mortality ratio was 2624 per 100,000 live births. The mean 
age of death was 26.79 with extremes of 15 years to 40 years. Direct obstetric 
causes accounted for 58% dominated by hypertension and complications, 
hemorrhage during pregnancy and postpartum, and obstetric infections. The 
indirect obstetric causes were 42% dominated by non-obstetric infections and 
chronic anemias. In addition to the delay in consultation and delay in care, 
the lack of antenatal care was the contributing factor to maternal deaths. Conclusion: Maternal mortality remains a public health problem in view of its high 
ratio. The reduction of this scourge will inevitably go through a health 
insurance that will allow the supply of quality care.


Introduction
Pregnancy is a normal condition that most women aspire to during their lifetime. Experience as jovial and exhilarating, give life can be quite dangerous. Maternal mortality is a major public health problem [1]. It remains an obsession not only for women and society but also for practitioners [2].
According to the World Health Organization (WHO), around 830 women die every day in the world because of complications related to pregnancy or childbirth. In 2015, 303,000 women died during or after pregnancy or childbirth [2] [3] [4]. Most of these deaths occurred in poor countries. Indeed the ratio of maternal mortality in 2015 was 239 per 100,000 live births in developing countries compared to 12 per 100,000 live births in developed countries [2] [3]. In Burkina Faso, this ratio was 330 per 100,000 live births [5].
The international community is committed to reducing maternal mortality through the Sustainable Development Goals [5]. In Burkina Faso, several efforts have been made to reduce maternal mortality. Among these efforts, we can mention the awareness of the population, developed systems of delegation of tasks for the management of obstetric and neonatal care emergency (SONU) and free delivery and emergency obstetric care since 2016. Despite the many interventions designed, maternal mortality remains high in Burkina Faso [2] [6].
The present study is a part of the annual review of maternal deaths in the obstetrics and gynecology department at CHUYO. This study aims to analyze the epidemiological, clinical, etiological and therapeutic aspects of maternal mortality in order to better refocus the activities of the department and to draw the attention of the health authorities to the problem.

Patients and Method
The study took place in the obstetrics and gynecology department at CHUYO. This is a descriptive cross-sectional study with retrospective collection of data.
The study included all maternal deaths that occurred between January 1 st 2016 and December 31 st 2016 for a one year period. Deaths prior to the patient's arrival in the obstetrics and gynecology department were excluded from the study.
The variables studied were age, residence, occupation, and obstetrical history such as parity. Data were collected from patient clinical records, death records, birth registers, hospital records and birth records at the CHUYO maternity ward. The data was entered and analyzed by a microcomputer using the statis-

 Frequency of maternal mortality
During the study period, the obstetrics and gynecology department at CHUYO registered 11,050 admissions, performed 7351 deliveries with 6897 live births (NV). There were 181 maternal deaths. The mortality ratio was 2624 deaths per 100,000 NV.  Socio-demographic characteristics of deceased patients

• Age
The average age was 26.6 ± 6.8 years with extremes of 15 and 40 years. There were 28 (15.5%) of all early pregnancies (patients under 19 years of age) and 07 (3.9% of maternal deaths) in late pregnancies (patients over 40 years of age).

• Occupation
The number of deceased women who had no income-generating activity (housewives and students) was 148% or 81.8% of cases.
• Parity Parity at the time of death was known in 180 patients. The average parity was 2.1 ± 2.1 with extremes of 0 and 11.
• Residence of deceased patients The patients who resided in the central region numbered 99% or 54.7%. Those from other regions more or less distant were 82% or 45.3%. The average distance traveled by patients residing outside Ouagadougou was 145.5 kilometers. Table  1 shows the characteristics of the deceased patients. The follow-up of the pregnancy was specified in 175 cases. The number of prenatal consultations ranged from 0 to 5 with an average of 1.8 ± 1.6.
• Gravido-purperal period at the time of death of the patient The distribution of patients who died by the gravid-puerperal period at the time of death is shown in Table 2.
• Place of delivery Health facility accounted for 92 cases or 98.9%. A home birth was found in our study.
• Mode of admission The patients referred or evacuated were 173% or 95.6% of deaths and those who came directly were 8% or 4.4%.
• Medical causes of death The distribution of medical causes of patient deaths is shown in Table 3.

 Treatment
Several types of treatment were administered to the patients before deaths.
The different treatments received figure in Table 4. These factors had as frequency: • Delayed consultation: 83 cases or 45.9%; • The delay in care in the health facilities: 74 cases or 40.8%; • Lack of antenatal care: 20 cases or 11.0%.  The delay in treatment consisted of the lack of labile blood products and the delay in transfusion (15 cases, 8.3%), the lack of financial means with prescription not honored (9 cases, 4.9%), delay in occupied block and/or incomplete kit surgery (11 cases or 6.1%) and evacuation delay for an unavailable ambulance and/or delay in the evacuation procedure (39 cases or 21, 5%).

Discussion
The maternal mortality rate was very high in our series (2624 deaths per 100,000 live births). It was 8 times the national rate of the country according to the WHO which was 330 per 100,000 live births but remains lower than that found by Zamané and al [5] which found a rate of 5369 per 100,000 live births at the Patients who died without any income-generating activity (housewives and students) were 148% or 81.7% of cases. This socio professional layer is the most affected as evidenced by Lankoandé et al. [11] who found 94 (76.4%) deaths among women without a profession. The maternal mortality rate is inversely related to the socio-economic level. Lack of money can affect the health status of women. Women's survival is closely linked to their health [12].
In our study, the number of patients treated or evacuated was 173% or 95.6% of deaths. This could be explained by the fact that CHUYO was at the same time as the organization of the health system. The lack of equipment and/or the lack of medical equipment and the lack of medical care of the ambulances in the reference structures on the one hand and the poor condition of the roads on the other hand make evacuations an important factor risk of maternal death. were the direct causes of maternal deaths in our study. The indirect hand causes of maternal death found in our study were non-obstetric infections (22 cases of malaria, 2 cases of acute meningitis, 11 cases of pneumonia and 4 cases of hepatitis) followed by chronic anemia (11.6%). Zamané et al. [5], Lankoandé et al. [11] in Burkina Faso, Kaur et al. in India [8] found in their studies that anemia Open Journal of Obstetrics and Gynecology was the indirect cause of maternal death. Anemia is most often multifactorial and may be associated with infection [5] [11].
In our study, the majority of patients died within 24 hours of admission. Our results are comparable to those of Lankoandé, Guerrier and Olamijulo who found that most women died within 24 hours of admission [7] [11] [15]. The high rate of maternal mortality in the Department of Obstetrics and Gynecology calls on the health authorities to implement life saving measures such as: -The establishment of a system of immediate care of patients. Indeed, the longest waiting time between the arrival and the first examination of the deceased patients was 45 minutes in our study. The delay in management was reported in 74 deceased patients, i.e. 40.8% of cases. The delays in the quality of medical care were positively associated with serious issues for the mother [16].
-The revision of the system of awareness of the population (interest of the follow-up of the pregnancy and the donations of blood). Indeed, in our study, the lack of prenatal follow-up (20 cases, i.e. 11%) was one of the maternal contributing factors to death, as was the lack of labile blood products (15 cases, or 8.3%).
-Universal health insurance. The lack of financial means with prescription not honored (9 cases or 4.9%) and the delay to surgery for incomplete kit (11 cases or 6.1% of cases) were contributing factors to maternal death.
-Improving the system for transferring patients to referral centers. In fact, the delay in evacuation for an unavailable ambulance (39 cases, or 21.5% of cases) was a contributing factor to the maternal death in our study.

Limitations
The limits of the study are those of a retrospective study on files sometimes summarily filled up urgently and badly archived. However, valuable information can be drawn for the organization of the department's archives.

Conclusion
From our study, it appears that maternal mortality remains a public health problem in view of its high ratio. The profile of the woman who dies in the gravid-puerperal period represents the young age and the unfavorable socio-economic status. The medical causes of maternal deaths are mainly direct obstetric causes.
As for the contributing factors, we found the delay in admission, the delay in first care, the lack of prenatal follow-up and the lack of financial resources. Despite free care, the record of maternal mortality is still heavy. The reduction of this scourge will inevitably go through a universal health insurance that will allow the provision of quality care.
