WHO antenatal care randomised trial for the evaluation of a new model of routine antenatal care

BACKGROUND We undertook a multicentre randomised controlled trial that compared the standard model of antenatal care with a new model that emphasises actions known to be effective in improving maternal or neonatal outcomes and has fewer clinic visits. METHODS Clinics in Argentina, Cuba, Saudi Arabia, and Thailand were randomly allocated to provide either the new model (27 clinics) or the standard model currently in use (26 clinics). All women presenting for antenatal care at these clinics over an average of 18 months were enrolled. Women enrolled in clinics offering the new model were classified on the basis of history of obstetric and clinical conditions. Those who did not require further specific assessment or treatment were offered the basic component of the new model, and those deemed at higher risk received the usual care for their conditions; however, all were included in the new-model group for the analyses, which were by intention to treat. The primary outcomes were low birthweight (<2500 g), pre-eclampsia/eclampsia, severe postpartum anaemia (<90 g/L haemoglobin), and treated urinary-tract infection. There was an assessment of quality of care and an economic evaluation. FINDINGS Women attending clinics assigned the new model (n=12568) had a median of five visits compared with eight within the standard model (n=11958). More women in the new model than in the standard model were referred to higher levels of care (13.4% vs 7.3%), but rates of hospital admission, diagnosis, and length of stay were similar. The groups had similar rates of low birthweight (new model 7.68% vs standard model 7.14%; stratified rate difference 0.96 [95% CI -0.01 to 1.92]), postpartum anaemia (7.59% vs 8.67%; 0.32), and urinary-tract infection (5.95% vs 7.41%; -0.42 [-1.65 to 0.80]). For pre-eclampsia/eclampsia the rate was slightly higher in the new model (1.69% vs 1.38%; 0.21 [-0.25 to 0.67]). Adjustment by several confounding variables did not modify this pattern. There were negligible differences between groups for several secondary outcomes. Women and providers in both groups were, in general, satisfied with the care received, although some women assigned the new model expressed concern about the timing of visits. There was no cost increase, and in some settings the new model decreased cost. INTERPRETATIONS Provision of routine antenatal care by the new model seems not to affect maternal and perinatal outcomes. It could be implemented without major resistance from women and providers and may reduce cost.

Effects of psychosocial support during labour and childbirth on breastfeeding, medical interventions, and mothers' wellbeing in a Mexican public hospital: a randomised clinical trial

Object To evaluate the effects of psychosocial support during labour, delivery and the immediate postpartum period provided by a female companion (doula).

“Alone, I wouldn't have known what to do”:A qualitative study on social supportduring labor and delivery in Mexico

This article presents some of the most relevant qualitative results of a trial to evaluate the effects of the provision of psychosocial support to first-time mothers during labor, childbirth and in the immediate postpartum period in a social security hospital in Mexico City. The article focuses on the experiences of mothers who have received psychosocial support from a doula (the term doula is used to identify a woman who provides continuous support to a woman during labor. delivery and the immediate postpartum period) and compares them with the experiences of those women who gave birth following normal hospital routine. Sixteen in-depth interviews were held with women in the immediate post partum period (eight of whom had been accompanied by a doula and eight who had not) before they were discharged from hospital, and the results were analyzed using qualitative techniques. The interviews showed that the women accompanied by a doula had a more positive childbirth experience. The differences between both groups related to their perceptions of the childbirth experience; the treatment they received from hospital staff; the information they were given and how well they understood it; their perception of hospital routines; their feelings about cesarean sections and, spatial and temporal perceptions. The most important difference between the two groups was the way they expressed their feelings about their own labor, their sense of control and their self-perception.

El embarazo no deseado: impacto sobre la salud y la sociedad en América Latina y el Caribe

Engaging in sexuality and reproduction should always be something that is wanted and planned. Unfortunately, when that is not the case, one result can be unwanted pregnancy. Unwanted pregnancies have consequences for women, their families, and their countries. This document reviews the causes and results of unwanted pregnancy, emphasizing the impact that this problem has on Latin America and the Caribbean (LAC). Four reasons why unwanted pregnancy is a continuing problem in LAC are: 1) peoples growing desire to have smaller families, 2) the unmet need for family planning, 3) the fact that contraceptive methods are not 100% effective, and 4) unwanted sexual relations. Unwanted pregnancies especially affect adolescent women, single women, and women over 40 years of age. Given their desperate situation with an unwanted pregnancy, some women opt for an unsafe abortion, which can lead to their death. Other women can go so far as to commit suicide, or be murdered by a family member or other person who is unhappy that the pregnancy has occurred. It has been found that women who decide to continue with the pregnancy have higher risks of suffering an illness, and the same is true for the child. Reducing unwanted pregnancies and treating post-abortion complications are key to lowering maternal mortality and morbidity. This necessitates developing mass communication programs that address gender issues, education programs for girls, and sex education programs. It is also vital to make available to all persons reproductive health services that include family planning methods. In the countries of LAC with laws that specify grounds for legally ending a pregnancy, it is necessary that health care be organized to actually provide this service, and that health care programs obtain the safest, most effective technologies now available for ending a pregnancy.

Emergency contraception in Mexico City: what do health care providers and potential users know and think about it?

Emergency contraception promises to reduce Mexicos high unwanted pregnancy and unsafe abortion rates. Because oral contraceptives are sold over-the-counter, several emergency contraceptive regimens are already potentially available to those women who know about the method. Soon, specially packaged emergency contraceptives may also arrive in Mexico. To initiate campaigns promoting emergency contraception, we interviewed health care providers and clients at health clinics in Mexico City, ascertaining knowledge, attitudes, and practices concerning the method. We found limited knowledge, but nevertheless cautious support for emergency contraception in Mexico. Health care providers and clients greatly overestimated the negative health effects of emergency contraception, although clients overwhelmingly reported that they would use or recommend it if needed. Although providers typically advocated medically controlled distribution, clients believed emergency contraception should be more widely available, including in schools and vending machines with information prevalent in the mass media and elsewhere.

Womens' opinions on antenatal care in developing countries: results of a study in Cuba, Thailand, Saudi Arabia and Argentina.

BackgroundThe results of a qualitative study carried out in four developing countries (Cuba, Thailand, Saudi Arabia and Argentina) are presented. The study was conducted in the context of a randomised controlled trial to test the benefits of a new antenatal care protocol that reduced the number of visits to the doctor, rationalised the application of technology, and improved the provision of information to women in relation to the traditional protocol applied in each country.MethodsThrough focus groups discussions we were able to assess the concepts and expectations underlying womens evaluation of concepts and experiences of the care received in antenatal care clinics. 164 women participated in 24 focus groups discussion in all countries.ResultsThree areas are particularly addressed in this paper: a) concepts about pregnancy and health care, b) experience with health services and health providers, and c) opinions about the modified Antenatal Care (ANC) programme. In all three topics similarities were identified as well as particular opinions related to country specific social and cultural values. In general women have a positive view of the new ANC protocol, particularly regarding the information they receive. However, controversial issues emerged such as the reduction in the number of visits, particularly in Cuba where women are used to have 18 ANC visits in one pregnancy period.ConclusionRecommendations to improve ANC services performance are being proposed. Any country interested in the application of a new ANC protocol should regard the opinion and acceptability of women towards changes.

The etiology of maternal mortality in developing countries: what do verbal autopsies tell us?

OBJECTIVE To reassess the practical value of verbal autopsy data, which, in the absence of more definitive information, have been used to describe the causes of maternal mortality and to identify priorities in programmes intended to save womens lives in developing countries. METHODS We reanalysed verbal autopsy data from a study of 145 maternal deaths that occurred in Guerrero, Querétaro and San Luis Potosí, Mexico, in 1995, taking into account other causes of death and the WHO classification system. The results were also compared with information given on imperfect death certificates. FINDINGS The reclassification showed wide variations in the attribution of maternal deaths to single specific medical causes. CONCLUSION The verbal autopsy methodology has inherent limitations as a means of obtaining histories of medical events. At best it may reconfirm the knowledge that mortality among poor women with little access to medical care is higher than that among wealthier women who have better access to such care.

A Study on Maternal Mortality in Mexico Through a Qualitative Approach

This report presents the main qualitative results of a verbal autopsy study carried out in three states of Mexico, which aimed at identifying the factors associated with maternal mortality that could be subject to modifications through concrete interventions. By reviewing death certificates issued in 1995, it was possible to identify 164 households where a maternal death had occurred. One hundred forty-five of these households were visited, and a precoded questionnaire was completed to explore socioeconomic and living conditions, as well as causes of death. An open-ended question to prompt the relatives to narrate all the facts that led to the maternal deaths was included in the questionnaire. This study presents an analysis of that question, focusing on the delays in the care-seeking process and organized according to the model of the three delays: in deciding to seek care, in reaching a care facility, and in actually receiving care after arrival. Additionally, problems related to quality of care are examined. For analysis of the accounts, structural, interactional/community, and subjective variables were identified that allowed refining of our understanding of the problem of maternal deaths. Finally, based on the findings of the study, this article presents a series of recommendations, highlighting that interventions should address the early stages of a complication and focus on decreasing the various forms of inequality (gender and socioeconomic) associated with the occurrence of maternal deaths.

Emergency contraception in Mexico City: knowledge attitudes and practices among providers and potential clients after a 3-year introduction effort.

Emergency contraception (EC) has the potential to reduce unwanted pregnancy significantly, in Mexico as elsewhere. Recent years have seen tremendous growth in programs and research devoted to expanding access to emergency methods worldwide. In Mexico City, we conducted a pre-intervention/post-intervention research study of one way to introduce EC. Following a baseline survey of family planning providers and clients in 1997, we organized and implemented a three-year program of training for health care providers and a multi-faceted information campaign for the general public, including a national toll-free hotline and website. In 2000, we again surveyed family planning clinic providers and clients, using instruments similar to those employed in the baseline study. EC awareness increased significantly from 13% of clients to 32%, and support jumped from 73% to 83%. Providers at study clinics improved method recognition from 88% to 100%.
