Mortalidade perinatal e evitabilidade: revisão da literatura

This is a literature review onperinatal mortality focusing its evitability. A Medline and Lilacs (Latin-America and Caribbean) search was conducted for the 90s. There are few research studies on this subject in Brazil due to the great number of underreported fetal deaths and the low quality information provided in death certificates. Different proposals for perinatal death classification are presented. Most are based on grouping the underlying causes of deaths in a functional system in order to facilitate the analysis. In the Wigglesworth classification system, one of the most recommended methods, deaths are related to the different stages of care for pregnant women and children, evidencing the possibilities of their prevention. The evitability approach of perinatal deaths in Brazil is highly recommended, as mortality rates are still very high and most of the deaths are considered avoidable. Premature deaths could be avoided improving the quality of health care. Besides improving the medical assistance, the organization of health care regarding pre-natal, birth and neonatal care must also be better developed to ensure access to qualified assistance.

Stillbirths: how can health systems deliver for mothers and babies?

The causes of stillbirths are inseparable from the causes of maternal and neonatal deaths. This report focuses on prevention of stillbirths by scale-up of care for mothers and babies at the health-system level, with consideration for effects and cost. In countries with high mortality rates, emergency obstetric care has the greatest effect on maternal and neonatal deaths, and on stillbirths. Syphilis detection and treatment is of moderate effect but of lower cost and is highly feasible. Advanced antenatal care, including induction for post-term pregnancies, and detection and management of hypertensive disease, fetal growth restriction, and gestational diabetes, will further reduce mortality, but at higher cost. These interventions are best packaged and provided through linked service delivery methods tailored to suit existing health-care systems. If 99% coverage is reached in 68 priority countries by 2015, up to 1·1 million (45%) third-trimester stillbirths, 201 000 (54%) maternal deaths, and 1·4 million (43%) neonatal deaths could be saved per year at an additional total cost of US

Pesquisa Nascer no Brasil: perfil da mortalidade neonatal e avaliação da assistência à gestante e ao recém-nascido

BackgroundCaesarean section rates in Brazil have been steadily increasing. In 2009, for the first time, the number of children born by this type of procedure was greater than the number of vaginal births. Caesarean section is associated with a series of adverse effects on the women and newborn, and recent evidence suggests that the increasing rates of prematurity and low birth weight in Brazil are associated to the increasing rates of Caesarean section and labour induction.MethodsNationwide hospital-based cohort study of postnatal women and their offspring with follow-up at 45 to 60 days after birth. The sample was stratified by geographic macro-region, type of the municipality and by type of hospital governance. The number of postnatal women sampled was 23,940, distributed in 191 municipalities throughout Brazil. Two electronic questionnaires were applied to the postnatal women, one baseline face-to-face and one follow-up telephone interview. Two other questionnaires were filled with information on patients’ medical records and to assess hospital facilities. The primary outcome was the percentage of Caesarean sections (total, elective and according to Robson’s groups). Secondary outcomes were: post-partum pain; breastfeeding initiation; severe/near miss maternal morbidity; reasons for maternal mortality; prematurity; low birth weight; use of oxygen use after birth and mechanical ventilation; admission to neonatal ICU; stillbirths; neonatal mortality; readmission in hospital; use of surfactant; asphyxia; severe/near miss neonatal morbidity. The association between variables were investigated using bivariate, stratified and multivariate model analyses. Statistical tests were applied according to data distribution and homogeneity of variances of groups to be compared. All analyses were taken into consideration for the complex sample design.DiscussionThis study, for the first time, depicts a national panorama of labour and birth outcomes in Brazil. Regardless of the socioeconomic level, demand for Caesarean section appears to be based on the belief that the quality of obstetric care is closely associated to the technology used in labour and birth. Within this context, it was justified to conduct a nationwide study to understand the reasons that lead pregnant women to submit to Caesarean sections and to verify any association between this type of birth and it’s consequences on postnatal health.

Social inequalities in perinatal mortality in Belo Horizonte, Brazil : The role of hospital care

This paper analyzes the association between perinatal mortality and factors related to hospital care during labor, considering that healthcare assessment is needed in order to reduce perinatal mortality. A population-based case-control study was conducted with 118 perinatal deaths (cases) and 492 births (controls) that took place in maternity hospitals of the Brazilian Unified Health System (SUS) in Belo Horizonte, Minas Gerais, Brazil. Male sex, prematurity, diseases during pregnancy, low birth weight, newborn diseases, lack of prenatal care, lack of partograph use during labor, and less than one fetus assessment per hour during labor were significantly associated with perinatal deaths. In the multiple regression analysis, lack of partograph use during labor and type of hospital were associated with perinatal deaths. These results indicate inadequate quality of care in maternity hospitals and show that health services structure and health care process are related to perinatal mortality due to preventable causes.

Atualização da lista de causas de mortes evitáveis por intervenções do Sistema Único de Saúde do Brasil

The perinatal mortality rate is still high in Belo Horizonte. This study investigated all 826 perinatal deaths taking place in 1999, focusing on the possibility of their prevention, using the Wigglesworth classification. The perinatal mortality rate was 20.2 per one thousand births, and the risk of perinatal death was 20 times higher in children with low birthweight. Some 24.6% of the children weighed more than 2,500g, and the main cause of death in this group was asphyxia during labor. The antepartum cause of death contributed to 30% of all deaths, and 25% of these children weighed more than 2,500g. Some deaths occurred out of hospital, and in some cases the mother arrived at hospital in end-stage labor. About 40% of all perinatal deaths or 60% of all early neonatal deaths could have been prevented, suggesting flaws in prenatal, intrapartum, and neonatal care at both the clinical and health-care organizational levels. To intervene in this situation, progress is needed in improving quality of care and ensuring accountability in the specific health services and the health care system as a whole.

Birth in Brazil survey: neonatal mortality, pregnancy and childbirth quality of care

Estudo de coorte sobre a mortalidade neonatal na pesquisa Nascer no Brasil, com entrevista e avaliacao de prontuarios de 23.940 puerperas entre fevereiro de 2011 e outubro de 2012. Utilizou-se modelagem hierarquizada para analise dos potenciais fatores de risco para o obito neonatal. A taxa de mortalidade foi 11,1 por mil; maior nas regioes Norte e Nordeste e nas classes sociais mais baixas. O baixo peso ao nascer, o risco gestacional e condicoes do recem-nascido foram os principais fatores associados ao obito neonatal. A inadequacao do pre-natal e da atencao ao parto indicaram qualidade nao satisfatoria da assistencia. A peregrinacao de gestantes para o parto e o nascimento de criancas com peso < 1.500g em hospital sem UTI neonatal demonstraram lacunas na organizacao da rede de saude. Obitos de recem-nascidos a termo por asfixia intraparto e por prematuridade tardia expressam a evitabilidade dos obitos. A qualificacao da atencao, em especial da assistencia hospitalar ao parto se configura como foco prioritario para maiores avancos nas politicas publicas de reducao das taxas e das desigualdades na mortalidade infantil no Brasil.This study examined neonatal deaths in the live-births cohort in the Birth in Brazil survey, which interviewed and examined medical records of 23,940 mothers from February 2011 to October 2012. Potential risk factors were analyzed using hierarchical modeling. Neonatal mortality rate was 11.1/1,000, the highest rates occurring in the North and Northeast regions and in lower social classes. Low birth weight, risks during pregnancy and conditions of the newborn were the main factors associated with neonatal death. Inadequate prenatal and childbirth care point to unsatisfactory quality of health care. Difficulty in gaining hospital admission for delivery, and children with birth weight<1,500g born at hospitals without a neonatal intensive care unit, indicate gaps in health system organization. Deaths from intra-partum asphyxia in term babies and late prematurity express preventable neonatal mortality. Better quality health care, especially hospital care during labor and birth, poses the main public policy challenge to progress in reducing mortality and inequalities in Brazil.

Implementação da presença de acompanhantes durante a internação para o parto: dados da pesquisa nacional nascer no Brasil

OBJECTIVES We examined the contribution of hospital type and quality of care to perinatal mortality rates in the city of Belo Horizonte, Brazil. METHODS We used a cohort study of all births (40953) and perinatal deaths (826) in Belo Horizonte in1999. After adjusting for maternal education and birthweight, we compared mortality rates according to hospital category--defined by a hospitals relation to the national Universal Public Health System (SUS)--and quality of care. We used the Wigglesworth Classification to examine perinatal deaths. RESULTS After we controlled for birthweight and maternal education, the highest perinatal death rates were observed in private and philanthropic SUS-contracted hospitals (relative to private, non-SUS-contracted hospitals). Hospital quality was also directly associated with perinatal death rates. Mortality rates were especially high for normal-birthweight babies born in private SUS-contracted hospitals. Intrapartum asphyxia was the leading cause of preventable death. CONCLUSIONS In a class-segregated health care system, such as Brazils, disparities in quality of care between SUS-contracted and non-SUS-contracted hospitals contribute to the unacceptably high rates of perinatal mortality.
