[Quality of caesarean delivery: A cross-sectional study in 12 hospitals in Benin]. / La césarienne de qualité : étude transversale dans 12 hôpitaux au Bénin.

BACKGROUND: Caesarean section (CS) is a major obstetric intervention, widely recognized as an effective means to reduce maternal and perinatal mortality, when appropriately performed. CS numbers and rates are regularly published but quality is rarely taken into account. This study aims to describe the quality of caesarean delivery in selected hospitals in Benin. METHODS: A cross-sectional study was performed among women who had undergone a CS between 18 December 2013 and 8 February 2014 in one randomly selected hospital in each of the 12 administrative districts of Benin. The quality of CS was defined according to the analytical framework of Dujardin and Delvaux (1998) with its four pillars (access, diagnosis, procedure, postoperative care). Data were collected from hospital files and questionnaires from women and hospital directors. Data analysis was performed using Epi Info 3.5.1. RESULTS: Six hundred and thirty-two women delivered by CS during the period and 579 were eligible for the study. They were aged 26.5±6.3 years, 73.2% living more than 5km from the hospital, 63.0% referred to a health facility of whom 46.0% and 21.8% were transported by motorcycle and by ambulance respectively. The median expenditure by family was FCFA 30 000, ranging from 0 to FCFA 200 000. The admission examination was complete in 12.6% of women and the partograph used in 32.6%. The average CS rate was 37.6%, the average response time, 124minutes. Emergency CS was performed in 80.7%, for absolute maternal indications in 48.0% and under spinal anesthesia in 84.2% (98.3% of which were conducted by a nurse or midwife anesthetist). Maternal mortality was 2000 maternal deaths per 100 000 deliveries, while perinatal mortality was 7.4% (88.4% due to stillbirths). CONCLUSION: CS in Benin hospitals partially fulfilled quality criteria. However access to CS remains difficult and errors of diagnosis or excessive delay are too frequent. Quality CS is not yet a reality in Benin hospitals.

[Social anthropological approach to tuberculosis in Mopti (Mali): popular representations and use of treatment]. / Approche socioanthropologique de la tuberculose à Mopti (Mali): représentations populaires et recours thérapeutiques en cas de tuberculose.

In Mali, there were 4508 new cases of tuberculosis in 2003, and 5222 in 2006. Tuberculosis (TB) is thus an important public health problem, decreasing the physical, financial and social capital of individuals, their families and society. Because responses to TB have not yet applied a sufficiently integrated approach that can improve patients' access to quality care, this FORESA project advocates a patient-centered approach. Before any intervention, FORESA thus sought to analyse the situation of TB in Mali and responses to it. The study aims to analyse the discourse about and popular representations of TB (its forms, its signs), the situations in which people are exposed to it or transmit it, and popular practices related to its prevention and the experience of having it. This qualitative, descriptive and analytical study includes a literature review, in-depth interviews with opinion leaders, community health workers and TB patients, focus groups, and the observations of practices. The interviews were recorded, transcribed, and analysed. Subjects provided informed consent to participation. This study showed that: * the terms for TB in local languages (Bambara, Dogon and Fulfuldé) include white cough, big cough, and long cough; * These communities differentiate between 2 main forms of cough (simple and wet); * TB is perceived as a transmissible disease, a disease of contact with a contaminated body or objects; * TB is seen as a serious, contagious, hereditary, shameful disease that may result from the transgression of social norms; * The prevention of TB consists of avoiding people who have the disease or transmitting factors; * Therapeutic remedies, in order, are self-medication, the use of traditional healers, and finally visits to health centres; * The population wants more information about TB and be involved in the fight against it. This study shows the many points of convergence about TB nosology, etiology and therapy between the Mopti population and other groups in Mali (including the Mande, Senoufo and Soso), between the population of Mali and some ethnic groups in Burkina Faso (such as the Dioula, Bobo, Tiéfo Vigué), and between the population of Mali and, Burkina Faso and others in Africa (Gambia, Nigeria, South Africa, etc.). There is also a difference between popular knowledge about TB and biomedical knowledge. The population does not know that TB is transmitted mainly, even exclusively, by nasal droplets or that patients are no longer contagious after two weeks of treatment. The widespread dissemination of this information may have a positive effect, reducing stigmatization and improving access to treatment. Mali must strengthen the skills of all participants in the fight against tuberculosis, to strengthen their framework and to monitor and evaluate their activities.

[A patient-centered approach to tuberculosis control in Burkina Faso]. / L'approche centrée sur le patient pour la lutte contre la tuberculose au Burkina Faso.

BACKGROUND: The Burkina Faso health system is divided into 55 health districts (DS), each with more than 10 primary care health centers (CSPS) that comprise the first level of the health care system. For this study, we chose two intervention districts (one rural, one urban) and two control districts. OBJECTIVE: To evaluate the impact of the patient-centered approach to tuberculosis control on the detection and treatment of tuberculosis. METHOD: This intervention, defined in a consensus process by various participants in tuberculosis management, was implemented in two districts (one rural and one urban). Study outcomes were measured before and after the intervention in two intervention districts and two control districts. RESULTS: The proportion of patients suspected of tuberculosis who chose sputum sampling in the CSPS was higher in the rural district (Gorom-Gorom) than in the urban one (Pissy): 46% versus 18.7% (p < 0.001). Detection improved more in the intervention than control districts (59% versus 20%). The increase in diagnosis was better in the intervention districts than in their matched control districts (46% versus 5% in the rural district; 75% versus 32% in the urban district). The treatment success rate was better in the rural district's decentralized CSPSs than in its CDTs (Gorom-Gorom) (61.8% vs 52.8%), while the reverse was true in the urban district (Pissy) (75% vs 83.1%). CONCLUSION: Detection of new tuberculosis cases increased throughout this study. Improvement in treatment regularity was limited. A longer intervention is needed to evaluate the effects of this approach on treatment results.

Conversion rate at two-month follow-up of smear-positive tuberculosis patients in Burkina Faso.

SETTING: Burkina Faso, West Africa. OBJECTIVE: 1) To determine the trend of sputum smear conversion rates at the 2-month follow-up of new smear-positive tuberculosis (TB) patients; and 2) to compare conversion rates in cured TB patients and treatment failures. DESIGN: Retrospective cohort study based on TB registers from all 80 diagnostic and treatment centres from 1995 to 2003. The conversion rate was defined as the number of negative results divided by the number of smear-positive patients for whom the 2-month follow-up examination was completed. RESULTS: The 2-month follow-up completion rate was 92.1%; it increased from 86.3% in 1996 to 94.3% in 2003. The conversion rate was 82.9%, increasing from 76.3% in 1995 to 87.9% in 1997 and falling to 80.3% in 2003. The cure rate was higher among patients who were smear-negative at the 2-month follow-up (77.3%) CONCLUSION: The conversion rate was satisfying, but had declined since 1997, which may be a matter of concern. This could be due to patient characteristics such as associated conditions (human immunodeficiency virus, malnutrition) or to drug management (ineffective administration of drugs even under directly observed treatment, insufficient dosages, resistance). Thorough research is needed to elucidate this negative trend.

Severe Yersinia enterocolitica sepsis after blood transfusion.

A 23-year-old male received multiple blood transfusions following complicated thoracic surgery. He developed progressive haemorrhagic shock and multiple organ dysfunction syndrome. Blood cultures grew Yersinia enterocolitica. The patient was proven negative for Yersinia enterocolitica; however, one of the donors was found to be positive. Although strict selection of blood transfusion donors is warranted in the Netherlands, contamination of blood components may still occur and therefore should be considered whenever adverse events occur during or after blood transfusion.

[Underweight prevention and treatment of the young child in Mono (Benin)]. / Prévention et traitement de l'insuffisance pondérale chez le jeune enfant du Mono (Bénin).

BACKGROUND: This study aimed to assess the prevention and treatment effectiveness of underweight in less than two years old children admitted in 2001 to community nutrition programme of Mono area in Benin. METHODS: A longitudinal retrospective survey took place in 30 villages chosen at random. It concerned a sample of 1799 children. Inside of those children, during the 2001 year, when they were admitted to the programme, 1545 were without underweight, have had more than one month following visit and about them the underweight effectiveness prevention had been analyzed; the others 111 were underweighted, have had more than one month following visit and about them the underweight treatment had been assessed. The 143 other children have been followed for only one month. The prevention effectiveness had been explored by the evolution of the cumulative incidence of underweight according to the number of following visit and the underweight incidence density. The treatment effectiveness has been analysed by calculating the recovery rate and incidence density. RESULTS: During 2001, there have been observed 10% for the underweight cumulative incidence and 51.4% for the cumulative incidence of underweight recovery. The underweight and recovery incidence density were respectively 14 cases for 1000 persons-months of following and 118 cases for 1000 persons-months of following. The children with serious underweight at their last following visit have had the number of following visits lower than those who were with moderate underweight. The recovery was arrived after two to twelve months. There was a significant increase of underweight prevalence with the increase of following visit number inside the children with a normal weight at their admission into the programme. CONCLUSION: During the 2001 following, the underweight prevention and treatment activities of community nutrition workers have been little effectiveness. The low level of instruction of community nutrition workers, their low level of knowledge of essential community nutrition activities, their multiple tasks and the not used appropriate foods for the treatment of underweight are the possible causes of the poor performance observed.

Are patients who present spontaneously with PTB symptoms to the health services in Burkina Faso well managed?

SETTING: Six health districts selected from a total of 53 in Burkina Faso. OBJECTIVE: To evaluate the performance of the health services in identifying infectious pulmonary tuberculosis (PTB) cases in Burkina Faso. DESIGN: Retrospective review of initial consultation registers in the first level health centres and the laboratory and treatment registers kept at the Centres for TB Diagnosis and Treatment (CDTs) in 2001. RESULTS: The rate of detection of sputum-positive cases of PTB was 11.7 cases per 100000 population. Cough was the reason for consulting for 10.6% of 248,730 adults; 1.1% had chronic cough. Among patients with chronic cough, 66% had been referred for smear microscopy, 69.7% of whom were registered at the CDT to which they were referred. A positive diagnosis was made in 22.5% of the suspects referred and traced to the CDT. Among those with a positive diagnosis, 87.1% were put on treatment in the same CDT. CONCLUSIONS: The PTB case detection rate in Burkina Faso is low, due to the loss of cases at each of the stages leading to the diagnosis of TB. Case detection depends on the operational effectiveness of the staff working in the health services, as well as the referral of suspect patients to the CDT.

[Emergency obstetrical care in Benin referral hospitals: 'near miss' patients' views]. / La qualité de prise en charge des urgences obstétricales dans les maternités de référence au Bénin: le point de vue des "Echappées Belles" et leurs attentes.

OBJECTIVE: To evaluate emergency obstetric care and the perceptions and expectations of women who experienced 'near miss' events to improve maternal health in Benin. METHODS: Qualitative survey in seven hospitals at the three referral levels of the health pyramid from July to October 2003. We used two methods: 557 women with near miss events were interviewed in hospital and a standard questionnaire completed; then semi-structured individual interviews were conducted at home with 42 of these 557 women. RESULTS: Provided care, accommodation, facilities, costs and modalities of recovery, hygiene of the premises, dynamism, expertise, social support, behaviours and attitude of staff were the criteria used to express patients' satisfaction. Most women interviewed in hospital were happy with physical access, organization, functioning and environment. However, excessive costs and coercive recovery of the expenses, failure of the referral system, lack of empathy and discrimination of the nursing staff, lack of resources for emergencies, lack of hygiene and comfort of the premises were criticized by the women interviewed at home. CONCLUSION: The current maternal care system fails to effectively deal with obstetric complications. It needs to be better resourced, more easily available, cheaper and take into account the women's needs.

[Validity, cost and feasibility of the mAECT and CTC confirmation tests after diagnosis of African of sleeping sickness]. / Validité, coût et faisabilité de la mAECT et CTC comme tests de confirmation dans la détection de la Trypanosomiase Humaine Africaine.

OBJECTIVES: To evaluate the validity, cost and feasibility of two parasitological tests for the confirmation of Human African Trypanosomiasis (HAT): the mini Anion-exchange Centrifugation Technique (mAECT) and Capillary Tube Centrifugation (CTC). METHODS: During a sleeping sickness screening campaign in 2004 we screened 6502 people in Kwamouth, DRC. Those with a positive result in the Card Agglutination Test for Trypanosomiasis (CATT) had a gland puncture, fresh blood examination, stained thick blood film, mAECT, CTC and CATT titration. Sensitivity and specificity of the confirmation tests were calculated using the combination of all parasitological tests as a reference standard. Each method was costed and its feasibility was assessed with structured interviews of the technicians. RESULTS: Sensitivity of classical parasitological methods was 44.8% (36.8-53.0), of CTC 56.5% (48.3-64.5) and of mAECT 75.3% (95% CI: 67.7-81.9). Cost per test was 2.82 Euro for mAECT and 0.76 Euro for CTC. Time per test was 29.78 min for mAECT and 18.25 min for CTC. These two tests were judged feasible in field conditions. CONCLUSION: CTC and mAECT used alone or in combination would bring a considerable improvement to HAT active case finding when used as confirmation tests in CATT-whole blood-positive persons. They proved feasible in operational conditions if a 220 V power supply can be guaranteed. As mAECT is more sensitive but also considerably more expensive, efficiency as well as feasibility considerations will have to guide the choice of the best algorithm.

Decentralising tuberculosis case management in two districts of Burkina Faso.

SETTING: In West Africa, national tuberculosis programmes (NTPs) face many problems due to the low performance of health care delivery systems and patients' social and cultural environment. OBJECTIVE: To improve the case management of TB in Burkina Faso. DESIGN: Using the operational research process as a tool, TB case management was decentralised from the district hospital to eight primary health care centres in 2003. RESULTS: Twelve months after decentralisation, the quality of case detection remained satisfactory. The delay between the identification of TB suspects with chronic cough and the confirmation of TB was reduced from 13 to 6 days. The detection rate of TB suspects during the study (30%) was twice as high as for 2001 and 2002 (15%). However, the detection rate for smear-positive TB cases decreased from 32.3% in 2001 and 2002 to 6.5% during the year of the study. CONCLUSION: Sufficient time and commitment are essential to obtain a case management system that is decentralised and effective. Efforts therefore need to continue to obtain more information and better results.

The cost of medical care and people's health-seeking behaviour before being suspected of tuberculosis in three local health systems, Nicaragua.

OBJECTIVE: To assess the medical costs incurred by users and delay between first contact with a care provider and sputum test for acid-fast bacilli (AFB) in three areas of Nicaragua. METHODS: Directed interviews of consecutive series of tuberculosis (TB) suspects whose sputum had been examined for AFB. RESULTS: Of 252 TB suspects interviewed, 52% used more than one type of care giver and 35% used private practitioners. As a consequence, 18%, 21% and 29% of the interviewees in Carazo, El Viejo and Matagalpa, respectively, spent more than 1 month of the country's median income per inhabitant on medical care between the first visit to a care provider and the first sputum examination. Furthermore, more than 3 months elapsed on that part of the care pathway for 30%, 17% and 3% of interviewees in Matagalpa, El Viejo and Carazo, respectively. CONCLUSION: This study sheds light on the costs and delays incurred by TB suspects before reaching a laboratory for sputum smear examination. Both costs are lower for those suspects who exclusively use first-line governmental health services (FLGHS). This has been relatively little documented in Latin America to date and could be used as an argument to develop strategies to strengthen the credibility of FLGHS.

[Effect of a participation in a community-based nutrition program on children's outcomes]. / Effet de la participation à un programme de nutrition communautaire sur l'état nutritionnel des enfants.

BACKGROUND: This study aimed to assess the effectiveness of a protein-energetic malnutrition prevention and treatment community program on the nutritional status of 18 to 36-month-old children in the poor communities of the Mono Region in Benin. METHODS: Two cross sectional anthropometric surveys were conducted. The first survey took place in 1998, before the implementation of the program; the second survey was conducted three years later. At each survey, cluster samples proportional to the population size was done; the sizes of the samples were 617 in 1998 and 648 in 2001. The nutritional status of 18 to 36 month-old-children was assessed by z-score of the indexes height-for-age, weight-for-age and weight-for-height and the cut-off point of -2 standard deviation was used to identify children who had stunting, wasting or underweight; children with serious stunting, wasting or underweight were identified with the cut-off point of -3 standard deviation. RESULTS: From 1998 to 2001, there was a significant reduction in the prevalence of growth retardation (-13.1%) and underweight (-13.0%). The reductions observed for the three types of protein-energetic malnutrition were more pronounced in the 30 to 36 months age group than in the others age groups. CONCLUSION: Substantial improvement was observed during the three years activities. This improvement cannot be attributed to the program unconditionally, because there was no difference between the nutritional status of participant and non participant children.

[Structural adjustment, cultural adjustment?]. / Ajustement structurel, ajustement culturel?

Over the last two decades, multiple studies have been conducted and many articles published about Structural Adjustment Programmes (SAPs). These studies mainly describe the characteristics of SAPs and analyse their economic consequences as well as their effects upon a variety of sectors: health, education, agriculture and environment. However, very few focus on the sociological and cultural effects of SAPs. Following a summary of SAP's content and characteristics, the paper briefly discusses the historical course of SAPs and the different critiques which have been made. The cultural consequences of SAPs are introduced and are described on four different levels: political, community, familial, and individual. These levels are analysed through examples from the literature and individual testimonies from people in the Southern Hemisphere. The paper concludes that SAPs, alongside economic globalisation processes, are responsible for an acute breakdown of social and cultural structures in societies in the South. It should be a priority, not only to better understand the situation and its determining factors, but also to intervene and act with strategies that support and reinvest in the social and cultural sectors, which is vital in order to allow for individuals and communities in the South to strengthen their autonomy and identify.

[Utilization of hospital emergency service for primary care (study at the Children's Hospital of Rabat, Morocco)]. / L'utilisation d'un service hospitalier d'urgences pour les soins de première ligne (étude à l'Hôpital d'Enfants de Rabat, Maroc).

BACKGROUND: Utilisation of emergency department (ED) for non-urgent problems, usually dealt with in first line health services (FLHS), has an impact both in terms of efficiency (ED care is more expensive than primary health care) and in terms of quality of care (due to ED overcrowding). This study describes the utilisation pattern of the ED at the Children's Hospital of Rabat (CHR) and assesses the appropriateness of ED utilisation. METHODS: During a whole week in September 1991, 24 h/24, information about every child admitted in the ED was collected by outside investigators, using a questionnaire. This questionnaire was divided into two sections. One section, filled out at admission of the child, consisted of the following items: time of arrival, health problem, health seeking pattern and identification of child (name, age, gender and address). The second section was filled out at the medical consultation and consisted primarily of a judgement about the relevance of ED utilisation (urgent/non-urgent condition, need for hospital-based equipment, subjective assessment of delay). RESULTS: During the week under study, 1,544 children were admitted at the ED: 904 at the medical ED and 640 at the surgical ED. At the medical ED, the proportion of urgent cases was 38%; among them, 65% needed hospital-based equipment and among the latter 72% arrived on time. It means that only 18% of the children utilised the ED in an appropriate way. At the surgical ED, the proportion of urgent cases was 56%; among them, 41% needed hospital-based equipment and among the latter 86% arrived on time. It means that only 20% of the children appropriately utilised the surgical ED. Appropriate utilisation is not associated with gender. The proportion of cases judged as urgent was associated neither to hour of admission--at least for the medical ED--nor to distance (less than 15 km). However, the proportion of urgent cases varied according to the day of the week. CONCLUSION: Results confirmed the opinion of the CHR staff: most children admitted to the ED had health problems that should have been cared for at FLHS. Rationalisation of ED utilisation will depend on the health system's ability to supply acceptable and accessible care at FLHS.

[Why patients do not comply with reference decision made by general practitioners?]. / Pourquoi les patients n'adhèrent-ils pas à la décision de référence faite par le médecin généraliste?

SUBJECT: A health system's efficacy depends on the efficacy of its different components (first-level health services and hospitals). It also depends on the system's ability to ensure the continuity of care among the various levels of the system. Health care officials in Settat Province, Morocco, found continuity in this province to be unsatisfactory. Depending on the health centre involved, only 31 to 52% of patients referred from the first to the second level of care reached the hospital. METHODS: The study was conducted in two rural and two urban health centres (HCs) covering a total population of around 94,000. The methodology consisted of two steps. First we analysed retrospectively various determinants (age, gender, distance, time until appointment) that might influence the compliance of patients referred by the four health centres in 1994. Then we observed curative medical consultations conducted in each of these health centres over a three-day period; the 38 patients referred to the hospital over this period were interviewed and the organisation of the hospital used on was analysed. RESULTS: The results revealed low compliance: only 43% (782/1807) of the patients referred actually consulted the hospital's departments. The compliance rates varied from one HC to the other and were lower in rural than urban areas taken as a whole (34% (207/607) versus 48% (575/1200), respectively). The interviews revealed that patients did not trust the last-year medical students who staffed the emergency rooms. Another organisational problem in the hospital was identified: patients referred to the hospital to consult a specialist were not seen immediately but given appointments at later dates, and these waiting times influenced the final success of the referral process. Thus, if the patients were seen immediately, compliance increased from 48 to 77% in the case of the urban HCs and from 34 to 67% in the case of the rural HCs. CONCLUSION: The most important determinants of compliance were above all associated with the way health services were organized and the quality of communication between health professionals and patients.

[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.

[Centralized purchasing of essential drugs, a priority for the health care systems of developing countries]. / Les centrales d'achat de médicaments essentiels: une priorité pour les systèmes de santé des pays en développement.

Health sector reform is a key priority of many governments throughout the world. Drug supply systems are a major element of public health policy design in Africa, where 90% of drugs are imported. The WHO Essential Drugs Program and the UNICEF sponsored Bamako Initiative have, since the late 1980s, promoted the rational use of essential drugs and attempted to ensure a sustainable drug supply through the implementation of cost recovery schemes and quality assurance mechanisms in public health services. A new market for drugs is emerging within this framework and there is growing competition for its control. Government medical stores are all too often bankrupt and the private sector is expensive, catering mainly for the middle to upper classes of urban areas. An intermediate alternative. Essential Drugs Purchasing Offices (EDPOs), has been proposed to balance social objectives and economic constraints. Some of the experimental strategies have given promising results. However, their implementation raises a number of questions: What is the role of the EDPO? Should it promote public health issues in general or focus purely on drug availability? What is the most appropriate legal status? Public or private? For profit or not? How should the investment capital be structured? In drugs or in funds? With ample provision or a tight budget? How should drug purchases be managed? Where should drugs be purchased? How much? How often? According to which procedures? How should the distribution of drugs be organized? Supplying everyone? Pushing supplies or pulling purchasers in? The answers to these questions, analysis of the reasons for success and failure and the dissemination of the information gathered should identify priorities for action and future research and define a framework for expansion. These are the objectives of the "Concerted Action for the Development of EDPO in Sub-Saharan African Countries" which is supported by the European Union (DG XII).

The value of maternal height as a risk factor of dystocia: a meta-analysis.

Ten publications and studies on the relation between maternal height and the risk of dystocia due to cephalopelvic disproportion (CPD) are analysed. The rate of Caesarean sections was chosen as the CPD indicator. When maternal height is presented in percentiles, curves can be superimposed, and sensitivities and specificities of the various studies may be analysed together. One biased study was excluded; the remaining 9 were pooled and regression lines calculated for sensitivity (Se) and specificity (Sp) of the entire set of points. The resulting model, i.e. Se = 10.9 + 1.99 Y and Sp = 99.9 - 0.99 Y, permits easy calculation of the expected sensitivity and specificity for each percentile Y. When the frequency of Caesarean section due to CPD is known, positive and negative predictive values can also be calculated. The proposed formulas can also be used to determine confidence intervals. The findings in terms of the sensitivity and specificity of low maternal height as a risk factor for dystocia indicate that 1 out of 5 pregnant women would have to be referred for further investigation to identify half of the cases of mechanical dystocia necessitating Caesarean section. The predictive value for a Caesarean rate of 2% (a value often seen in developing countries) for this 20th percentile would be only 5%. Practical ways of choosing a reference criterion are suggested. A two-track strategy (antenatal check-ups and community monitoring) is proposed.
