Assisted vaginal delivery in low and middle income countries: an overview.

OBJECTIVE: To assess the use of assisted vaginal delivery (AVD) in low- and middle-income countries (LMICs), highlighting what level of care procedures were performed and identifying systemic barriers to its use. DESIGN: Cross-sectional health facility assessments. SETTING: Up to 40 countries in Latin America, sub-Saharan Africa and Asia. POPULATION: Assessments tended to be national in scope and included all hospitals and samples of midlevel facilities in public and private sectors. METHODS: Descriptive secondary data analysis. MAIN OUTCOME MEASURES: Percentage of facilities where health workers performed AVD in the 3 months prior to the assessment, instrument preference, which health workers performed the procedure, and reasons AVD was not practiced. RESULTS: Fewer than 20% of facilities in Latin America reported performing AVD in the last 3 months. In sub-Saharan Africa, 53% of 1728 hospitals had performed AVD but only 6% of nearly 10 000 health centres had done so. It was not uncommon to find <1% of institutional births delivered by AVD. Vacuum extraction appears preferred over forceps. Lack of equipment and trained health workers were the most frequent reasons for non-performance. CONCLUSIONS: The low use of AVD in LMICs is in contrast with many high-income countries, where high caesarean rates are also associated with significant rates of AVD. In many LMICs, rising caesarean rates have not been associated with maintenance of skills and practice of AVD. AVD is underused precisely in countries where pregnant women continue to face hardships accessing emergency obstetric care and where caesarean delivery can be relatively unsafe. TWEETABLE ABSTRACT: Many LMICs exhibit low use of assisted vaginal delivery where access to EmONC continues to be a hardship.

The attitude and knowledge of cervical cancer by Cameroonian women; a clinical survey conducted in Maroua, the capital of Far North Province of Cameroon.

This study was conducted to assess the knowledge, attitudes, and assumption of cervical cancer by women living in Maroua, the capital of the Far North Province of Cameroon. In a 1-month period, 171 women were surveyed as to their socioeconomic status, sexual habits, prior knowledge of cervical cancer, its prevention, and their attitudes toward cervical cancer. Of 171 women, 48 (28%) had prior knowledge of cervical cancer; they were classified as the "aware group" compared with 123 of 171 (72%) women who were uninformed about cervical cancer and they were classified as the "unaware group" (UG). The UG of women tended to be single mothers, illiterate, housewives, and had their first child before the age of 20 (P < 0.005). Despite the awareness of cervical cancer by 28% of women, only a minority of them, 4 of 48 (8.3%), underwent a preventative screening test. Only 71 of 171 (41.5%) women stated that they would be having a screening test in the future. The awareness of cervical cancer by women in Cameroon is still inadequate. Thus, to avoid deaths from cervical cancer, a curable and preventable disease, the need of an aggressive campaign to make Cameroonian women aware of cervical cancer and its prevention is needed.

[Knowledge, attitude and perception about obstetric fistula by Cameroonian women]. / Connaissance, attitude et perception vis-à-vis des fistules obstétricales par les femmes camerounaises Une enquête clinique conduite à Maroua, capitale de la province de l'extrême Nord du Cameroun.

INTRODUCTION: This study seeks to identify what the women who live in Maroua Cameroon know and think about obstetric fistula. POPULATION AND METHOD: It is a single hospital, cross-sectional, descriptive and comparative study. Ninety-nine women in the maternity service of the Maroua Provincial Hospital were interrogated on obstetric fistula between May and July 2005, by enquirers who were trained health agents using a questionnaire which required both closed and open answers. RESULTS: The women who had no previous knowledge of it were generally the illiterate (41.7% compared to 18.8%). More than a third of the women who had an idea of the fistula do not know that there is a surgical treatment for it. Whether they had the previous information on fistula or received it from us, one-tenth of the women suggested that suicide was the solution to fistula where as one-third of the women suggested that a patient suffering from fistula should be isolated. CONCLUSION AND INTERPRETATION: Illiteracy contributes significantly to the lack of knowledge of this affection. The population has a poor perception and a strong negative attitude towards obstetric fistula as they see isolation or suicide as the solution to it.

Obstetric fistula: guiding principles for clinical management and programme development, a new WHO guideline.

It is estimated that more than 2 million women are living with obstetric fistulas (OFs) worldwide, particularly in Africa and Asia, and yet this severe morbidity remains hidden. As a contribution to the global Campaign to End Fistula, the World Health Organization (WHO) published Obstetric fistula: Guiding principles for clinical management and programme development, a manual intended as a practical working document. Its 3 main objectives are to draw attention to the urgency of the OF issue and serve as an advocacy document for prompt action; provide policy makers and health professionals with brief, factual information and principles that will guide them at the national and regional levels as they develop strategies and programs to prevent and treat OFs; and assist health care professionals as they acquire better skills and develop more effective services to care for women treated for fistula repair.

"Good obstetrics" revisited: too many evidence-based practices and devices are not used.

INTRODUCTION: As countries are designing and implementing strategies to address maternal and newborn mortality and morbidity (Millennium Development Goals 5 and 4), it appears that a large number of evidence-based obstetric practices are not used in many settings, and this is a major obstacle to the improvement of quality obstetric care. OBJECTIVES: To remind readers of the existing, relatively easy-to-implement, evidence-based interventions that are currently not being universally applied in obstetric care and, second, to foster research to expand the evidence base further for obstetric care practices and devices, especially those that could be used in resource-poor settings. METHODS: We review possible reasons why changes into practices are difficult to obtain, and we list the key evidence-based interventions known to effectively deal with the main obstetric complications, with supporting references and sources of documentation. We also list some promising interventions that require more research before being recommended. CONCLUSION: Professionals and health services managers have a crucial role in producing the best quality obstetric and neonatal care through implementing the listed evidence-based interventions and make them accessible to all pregnant women and their newborns without delay, even in poor settings. Reasons for which progress is slow should be addressed. One of these reasons being the lack of access to scientific knowledge from the part of professionals in developing countries, we give the key references and also websites which are freely accessible through the Internet. It is hoped that this paper will stimulate the discussion on the dissemination and use of good obstetric practices, and contribute to better maternal and newborn health.

Evidence for a 'healthy pregnant woman effect' in Niakhar, Senegal?

BACKGROUND: Although it is generally believed that pregnancy exposes women to a wide variety of excess health risks that go beyond the direct obstetric complications of pregnancy, the epidemiological evidence in support of such excess indirect risks is inconclusive. In this article we attempt to document the contribution of indirect causes of death to maternal mortality in rural Senegal by using an epidemiological approach whereby the time spent during pregnancy and postpartum is considered a transient period of exposure to the health hazards of childbearing. METHODS: We use data from an ongoing demographic surveillance system in Niakhar, Senegal and calculate rate ratios comparing death rates in pregnant or recently pregnant women (exposed) with death rates in other women (unexposed), including and excluding direct obstetric deaths. RESULTS: Between ages 20 and 44, pregnancy does not confer additional risks to women. After excluding direct obstetric deaths, exposed women aged 20--39 have surprisingly lower risks of death than unexposed women of the same age. For the very young (15-19) and the very old (45-49), on the other hand, the excess risks associated with pregnancy are considerable and, among women age 45 or older, persist even after excluding direct obstetric deaths. CONCLUSION: The apparent protective effect of pregnancy on women's health that is observed in this study illustrates the paradoxical nature of the concept of indirect causes of maternal mortality, and the difficulties in measuring the risks of death attributable to the pregnancy. Further studies aimed at separating risks attributable to the pregnancy from those that are incidental to the pregnancy are required.

[Vaginal cesarean for fetal deaths in utero]. / Césarienne vaginale dans les morts foetales in utero.

Among a series of 100 cases of retroplacental hematomas we performed vaginal cesareans in 15 and present here the technical difficulties, solutions and indications of this procedure in case of in utero fetal death. Criteria for choosing vaginal cesarean were: term les than 32 weeks, biparietal diameter > 80 mm, fetal weight < 2500 g. The main difficulty was the disproportion between the size of the fetus and the cervical orifice due to insufficient anterior trachelotomy. Possible solutions are posterior trachelotomy or craniotomy. This procedure is rapid and causes little blood loss and important advantage in case of impaired hemostasis.

[Determinants of risk factors associated with severe maternal morbidity: application during antenatal consultations]. / Le poids des facteurs de risque de la morbidité maternelle grave: application à la fiche de consultation prénatale.

In order to assess the incidence of severe maternal mortality (SMM) and search for associated determinants of risk factors, a population-based survey of 20,326 pregnant women was conducted in six counties in West Africa (MOMA study). Complete files were available for 19,545 (96.2%) women. The rate of SMM, assessed with an overall indicator, was 6.7% (5.7-6.4). The relationship between SMM and various socio-economic features, gyneco-obstetrical antecedents and characteristics of the current pregnancy was studied. Multivariate analysis identified 10 factors of risk of SMM. Prevalence, adjusted odds-ratio, positive predictive value and adjusted attributable risk were determined for these ten factors. By decreasing order of positive predictive value, these factors were: hemorrhage during pregnancy (51.5%), antecedent cesarean (27.1%), high blood pressure (diastolic pressure 10 (18.9%), systolic pressure 14 (14.6%)), antecedent multiple pregnancy (15.8%), height 150 cm (12.9%), lack of fetal movements (12.6%), history of 3 stillborns (9.3%), age over 35 years (8%), nulliparity (7.3%), presence of disease during the pregnancy (7.1%). These results show the importance of antenatal consultation during which these factors are easily identifiable.

[Potential role of prenatal care in reducing maternal and perinatal mortality in sub-Saharan Africa]. / Rôle potentiel de la consultation prénatale dans la lutte contre la mortalité maternelle et la mortalité néonatale en Afrique sub-saharienne.

Prenatal care has been implemented in developing countries according to the same mode as applied in industrialized countries without considering its real effectiveness in reducing maternal and neonatal mortality. Several recent studies suggest that the goals should be revisited in order to implement a program of prenatal care based on real scientific evidence. Based on the current literature, we propose a potentially effective content for prenatal care adapted to the context of developing countries. Four antenatal consultations would be enough if appropriately timed at 12, 26, 32 and 36 weeks pregnancy. The purpose of these consultations would be: 1) to screen for three major risk factors, which, when recognized, lead to specific action: uterine, scare, malpresentation, premature rupture of the membranes; 2) to prevent and/or detect (and treat) specific complications of pregnancy: hypertension, infection (malaria, venereal disease, HIV, tetanus, urinary tract infection); anemia and trace element deficiencies, gestational diabetes mellitus; 3) to provide counseling, support and information for pregnant women and their families (including the partner) concerning: severe signs and symptoms of pregnancy and delivery, community organization of emergency transfer, delivery planning. These potentially effective actions can only have a real public health impact if implemented within an organized maternal health system with a functional network of delivery units, if truly quality care is given, and if the relationships between health care providers and the population are based on mutual respect. Sub-Saharan African women use prenatal care extensively when it is accessible; this opportunity must be used to implement evidence-based actions with appropriate and realistic goals.

[Estimate of expected cesarean section rate for maternal indications in a population of pregnant women in West Africa (MOMA survey)]. / Estimation du taux attendu de césariennes pour indications maternelles dans une population de femmes enceintes d'Afrique de l'Ouest (enquête MOMA).

OBJECTIVES: There is still some debate about the optimal rate of cesarean section (CS) needed to achieve better outcome for both mothers and infants in developing countries. We examine here two aspects of the question: i) a simple method to estimate the expected rate of CS according to obstetrical risk; ii) a test of the method to estimate the appropriate rate for maternal indications in a general population of pregnant women in West Africa. METHODS: This population-based study was conducted in a cohort of pregnant women in six West African countries (MOMA survey): Abidjan (Ivory Coast), Bamako (Mali), Niamey (Niger), Nouakchott (Islamic Republic of Mauritania), Ouagadougou (Burkina Faso), and in three areas of Senegal, two small towns (Fatick and Kafrine, Kaolack region), and one major city (Saint-Louis). 19,459 women with singleton pregnancies with expected breech presentation were followed to delivery and puerperium. Maternal indications for CS were defined as dystocia (prolonged labor over 12 hours), malpresentation, previous cesarean section, abruptio placentae, placenta paevia and eclampsia. A standardized method was used to calculate the number of expected CS in the MOMA population, according to the level of the obstetrical risk. RESULTS: The minimal needs for Cs for maternal indications were estimated between 3.6 and 6.5 per 100 deliveries. However, we observed a rate of 1.3 CS per 100 deliveries. DISCUSSION: These findings underline the lack of CS for maternal indications in urban West Africa. The method of standardization we propose could help policy makers, health planners and obstetricians to design programs to reach the appropriate level of CS and to monitor and follow-up these programs.

[Maternal morbidity and qualification of health-care workers: comparison between two different populations in Senegal]. / Morbidité maternelle et qualification du personnel de santé: comparaison de deux populations différentes au Sénégal.

OBJECTIVE: High fertility rates and high maternal mortality ratios have led most cooperation agencies to place high priority on health of women and children. The objective of this study was to compare maternal morbidity and mortality tin two populations with widely contrasting availability of health care in order to test the hypothesis that differences in maternal outcome mainly result from the qualification of health carers. METHODS: This population-based study included a cohort of pregnant women which was part of a multicenter study of maternal morbidity in six countries in West Africa (MOMA). We compared health outcome in two different populations of Senegal (Saint-Louis and Kaolack).3,777 pregnant women were follow through pregnancy, delivery and pureperium. Maternal morbidity was assessed from the women's recall at each visit of the investigator and from obstetric complications diagnosed by the birth attendant within health facilities. RESULTS: Maternal mortality was higher in the Kaolack area where women gave birth mainly in district health care centers, most often assisted by traditional birth attendants, than in Saint-Louis where women giving birth in health facilities were principally referred to the regional hospital and were generally assisted by midwives (874 and 151 maternal deaths per 100,000 live births respectively, p<0.01). Diagnosed maternal morbidity, however, was higher in Saint-Louis than in the Kaolack area, especially for births in health facilities (9.50 and 4.84 episodes of obstetric complications per 100 lie births respectively, p<0.01). Univariate and multivariate analyses showed that diagnosed morbidity was mainly associated with degree of training of the health attendant in facility deliveries and that antenatal care had no effect. DISCUSSION: Midwives in health facilities appear to detect more obstetric complications than traditional birth attendants. Immediate detection leads to immediate care and to a lower case-fatality rate. This could explain the differences in maternal outcome between two urban centers with contrasting health care availability. CONCLUSION: These results suggest that one of the strongest weapons in the fight against maternal mortality is the employment of the most qualified personnel possible for monitoring labor.

[Uterine rupture in Senegal. Results of 2 surveys taken in 1992 and 1996]. / Ruptures utérines au Sénégal. Résultats de deux enquêtes effectuées en 1992 et 1996.

OBJECTIVES: National prospective descriptive study on dystocia were conducted in Senegal in 1992 and 1996. We examined more closely the data on uterine rupture to determine trends between these two surveys. METHODS: Data were collected for all patients undergoing an obstetrical intervention between January 1st and December 31st in 1992 and in 1996 in one of the referral maternity-obstetrical surgery units in each of the 10 regions in Senegal. RESULTS: The rate of uterine rupture was 1 per 51 interventions in 1992 (1.87%) versus 1 per 53 interventions in 1996 (1.94%). This dramatic event was recurrent in 7 of the 10 regions. The patients involved were aged 25-35 years (68% in 1992 versus 70% in 1996), multiparous or grand multiparous (52% in 1992 versus 70% in 1996), illiterate (90%), with poor follow-up (less than 3 prenatal consultations in 56% of the cases), and were generally evacuated to the unit (80% in 1992 versus 97% in 1996) without medical care (55%). Maternal mortality was high (28% in 1992 versus 12% in 1996). Infant mortality was also very high (98% in 1992 versus 86.6% in 1996). Conservative treatment of uterine rupture was used increasingly: the rate of conservative suture rose from 3.3% in 1992 to 22% in 1996. CONCLUSION: Prevention is a challenge for healthcare workers, public authorities and the population in general. Health policy should be directed towards forming general practitioners in obstetrical surgery. Emergency surgery kits should be made available to improve the quality of care in all maternity units throughout the country.

[Obstetric complications of the first trimester in Western Africa]. / Complications obstétricales du premier trimestre en Afrique de l'Ouest.

The obstetrical complications affecting women in Benin, Senegal and Ivory Coast during the first trimester of pregnancy were studied. Information about the 345 women included in the study was collected from registers maintained by the eight participating maternity units. The most frequent complications observed were spontaneous abortions (50% of admissions), complications of induced abortions (34%), and ectopic pregnancy (8%). Overall, the patients appear to have gained rapid access to care: two thirds of the women underwent interventions on the day of admission. Nevertheless, there were three maternal deaths, two of which followed induced abortion complications.

[Maternal mortality in developing countries: what strategies to adopt?]. / Mortalité maternelle dans les pays en développement: quelles stratégies adopter?

Despite an international consensus on the strategies necessary to achieve a massive reduction of maternal mortality and related neonatal mortality, many countries have made no progress in these areas. The main reason for this failure is that this aspect of public health and the basic human right to bear children under acceptably safe and respectable conditions have received neither sufficient attention from governments in developing countries nor long-term technical and financial support from rich countries. Yet a sound health care system that is accessible to the poorest classes is prerequisite for durable socio-economic development. Implementation of the UN Millennium Development Goals (MDG) provides an excellent opportunity to reaffirm the need for massive support of programs undertaken in this domain by developing countries and for implementation of an effective strategy to enhance access to quality care for the poorest classes. The purpose of this article is to review the main points in a strategy to reduce maternal mortality, i.e., use of practices with documented effectiveness; access to qualified personal during pregnancy and delivery; availability of health services and underlying facilities; the role of individuals, families, and communities; and the political and legal framework. This article also stresses the fact that programs designed to enhance maternal and newborn health can significantly strengthen the health care system for the community as a whole: maternal health offers a gateway for strengthening health care services in general.

[Uterine rupture in Senegal. Epidemiology and quality of management]. / Rupture utérine au Sénégal. Epidémiologie et qualité de la prise en charge.

The purpose of this prospective longitudinal study was to analyze data concerning patients treated for uterine rupture at surgical maternity hospitals in Senegal between January 1 to December 31, 1996. A total of 50 cases of uterine ruptures were recorded during the study period, i.e., 1 rupture for every 45 cesarian sections. Typical epidemiological features were rural residence (68%), age over 30 years (66%), multiparity (64%), and presence of obstetrical risks factors (76%). In 96% of cases, rupture usually occurred after failure or natural delivery assisted by personnel with limited skills in non-surgical facilities. Treatment consisted of uterine suture in 22% of cases and obstetrical hysterectomy in 78%. As a result of poor facilities for emergency transportation (68% of cases), mean delay between the indication for operative treatment and intervention was 11 hours. Maternal mortality and morbidity were 16% and 14% respectively. Neonatal mortality was 95%. The incidence of uterine rupture could be lowered by improving emergency obstetrical care and identifying risk factors for dystocia during prenatal examinations.

[Cesarean sections in Senegal: coverage of needs and quality of services]. / Césariennes au Sénégal: couverture des besoins et qualité des services.

A prospective longitudinal study was carried out of all women undergoing Cesarean section in the surgical maternity hospitals of Senegal between January 1 and December 31 1996. The epidemiology and quality of Cesarean sections were investigated. For each case, the following data were recorded: marital status, prenatal monitoring, conditions of hospitalization, indications for and outcome of surgery, maternal and neonatal follow-up one month after the operation. 2,436 Cesarean sections were performed. Of these, 2,269 cases were indexed and filed and 1,612 received a postnatal checkup one month after the operation. The mean age of the women involved was 26 years. The referral system is not effective, with 58% of patients being rushed to a surgical maternity unit in medically unsuitable forms of transport. Cesarean section is not widely available either geographically or economically. The mean national rate of Cesarean section was 0.6% of expected births but there were differences between regions. The main indications for Cesarean section were the fetus being too large to pass through the pelvic girdle (30%) and fetal suffering (18%). The maternal mortality rate was 3% and one third of the women who died did so immediately after the operation. Maternal morbidity occurred in 10% of cases, mainly due to postoperative infection. The rate of perinatal stress was 25%, most deaths being caused by neonatal distress (33%) or infection (18%). Thus, overall, both the availability and quality of Cesarean section in Senegal are poor.

PIP: A prospective study was conducted of all women delivering by cesarean section in Senegal's 22 surgical maternity hospitals during 1996. Adequate data were available to include 2269 of the 2436 cesareans performed. 13 hospitals performing 55% of the cesareans were in the Dakar area. Two of Senegal's 9 regions had no surgical maternity hospital and 4 had no gynecologists. 19.5% of the mothers were adolescents, and the average maternal age was 26 years. 46.5% were primiparous. 64% of the mothers were urban. 65% had at least 3 prenatal consultations and 12% had none. Only 28% were referred for cesareans before the onset of labor, and 57% were emergency evacuations. 6.7% of the women had to be re-evacuated from supposedly ultimate referral hospitals due to lack of supplies or personnel. 41% were transported to the hospital in ambulances, 14% in private cars, and 44% by public transportation. The 2436 cesareans corresponded to a rate of 0.6% of expected births, only 20% of the minimum need for cesareans estimated at 3%. Regional cesarean rates ranged from 1.3% in Dakar to 0.1% in Kaolack-Fatick. Feto-pelvic disproportion (30.4%) and fetal distress (18.2%) were the most common indications. 73 maternal deaths occurred, for a rate of 3%. 10% of the women had complications, with 55% involving infection. There were 9 cases of vesicovaginal fistula. The perinatal mortality rate was 25%, with 13% intrapartum and 13% neonatal. Neonatal distress and infection were the main causes of early neonatal death. Accessibility of cesareans is poor both geographically and economically.

Prevention in Obstetrics.

PIP: This special issue deals with prevention in the field of obstetrics. This prevention is conceptualized as having 3 aspects: education and preparation for childbirth, prevention of the risks known to be associated with pregnancy, and detection of high risk pregnancies. It is noted, however, that advances in this area are dependent upon improvements in basic living conditions in developing countries and in general public health. Thus, the health team must be fully trained in fields such as epidemiology, hygiene, and nutrition as well as obstetrics. The chapters in this volume provide detailed information on the components of prenatal care in the 3 stages of pregnancy, the surveillance of labor, and issues relevant to the postpartum period, including breastfeeding. Signs and symptoms of specific complications of pregnancy and delivery are detailed. An emphasis is placed on parameters that can be used for surveillance and subsequent evaluation and program development. The volume concludes with a discussion of family planning. Planned parenthood is stressed as a vital component of prevention in obstetrics, since pregnancies at short intervals threaten the health status of both mother and infant. Appendices to the volume present information on nutrition during pregnancy, medications used during pregnancy and delivery, and equipment considered necessary for use in obstetrical care.^ieng

Evaluation of iron status in Chadian pregnant women: consequences of maternal iron deficiency on the haematopoietic status of newborns.

An assessment of iron status was performed on 112 pregnant women at delivery (and on their newborns in 70 cases) and on 114 menstruating women in N'Djamena, Chad. Anaemia (according to the haematocrit value) was observed in 25.0% of pregnant women and in 23.7% of menstruating women. Iron deficiency was defined as the combination of a low serum ferritin level (less than or equal to 12 micrograms/l), a low transferrin saturation (less than 16%) and/or a high erythrocyte protoporphyrin (greater than 3 micrograms/g Hb). A moderate increase in the serum ferritin level (between 13 and 50 micrograms/l) associated with a low transferrin saturation and/or a high erythrocyte protoporphyrin concentration indicated iron-deficiency in an inflammatory context. Iron deficiency was present in 66.9% of pregnant women and in 30.7% of menstruating women. Anaemia was associated with iron deficiency in 78.6% of cases in anaemic pregnant women and in 44.4% of cases in anaemic menstruating women. A correlation between maternal and newborn haematopoiesis was found, and some iron parameters in newborns were related to the iron status of mothers.

Caesarean section rate for maternal indication in sub-Saharan Africa: a systematic review.

INTRODUCTION: Rates of caesarean sections in more-developed countries have been rising since 1970, and vary greatly between less-developed countries. Present estimates, based on data from more-developed countries need to be validated with data from less-developed countries. We estimated the need for caesarean section for maternal indication in a population of pregnant women in west Africa (MOMA survey). METHODS: The expected caesarean section rate was calculated from the rate of obstetric risk in the MOMA population, and rates of caesarean section in published work. FINDINGS: Three-quarters of women from hospitals of sub-Saharan Africa were delivered by caesarean section for maternal reasons. Such intervention was needed for six main reasons, protracted labour, abruptio placentae, previous caesarean section, eclampsia, placenta praevia, and malpresentation. Although the observed rate of caesarean section in west African women is 1.3%, our results, combined with those of published work suggest a range of 3.6-6.5% (median, 5.4%). INTERPRETATION: Our method might not be strictly accurate, but it is simple and provides informative findings that can help policy makers and health planners in sub-Saharan Africa to design and follow up programmes to reach the optimum caesarean section rate. Moreover, application of this method to hospital data could improve practitioners' assessments in these countries.

Severe maternal morbidity from direct obstetric causes in West Africa: incidence and case fatality rates.

Data on maternal morbidity make it possible to assess how many women are likely to need essential obstetric care, and permit the organization, monitoring and evaluation of safe motherhood programmes. In the present paper we propose operational definitions of severe maternal morbidity and report the frequency of such morbidity as revealed in a population-based survey of a cohort of 20,326 pregnant women in six West African countries. The methodology and questionnaires were the same in all areas. Each pregnant woman had four contacts with the obstetric survey team: at inclusion, between 32 and 36 weeks of amenorrhoea, during delivery and 60 days postpartum. Direct obstetric causes of severe morbidity were observed in 1215 women (6.17 cases per 100 live births). This ratio varied significantly between areas, from 3.01% in Bamako to 9.05% in Saint-Louis. The main direct causes of severe maternal morbidity were: haemorrhage (3.05 per 100 live births); obstructed labour (2.05 per 100), 23 cases of which involved uterine rupture (0.12 per 100); hypertensive disorders of pregnancy (0.64 per 100), 38 cases of which involved eclampsia (0.19 per 100); and sepsis (0.09 per 100). Other direct obstetric causes accounted for 12.2% of cases. Case fatality rates were very high for sepsis (33.3%), uterine rupture (30.4%) and eclampsia (18.4%); those for haemorrhage varied from 1.9% for antepartum or peripartum haemorrhage to 3.7% for abruptio placentae. Thus at least 3-9% of pregnant women required essential obstetric care. The high case fatality rates of several complications reflected a poor quality of obstetric care.
