Temporal trends and projections of caesarean sections in Brazil, its administrative macro-regions, and federative units. / Tendências temporais e projeções de cesariana no Brasil, macrorregiões administrativas e unidades federativas.

Trend studies on the model of birth in Brazil show a scenario of successive linear increases in cesarean rates. However, they ignore possible changes in the temporal evolution of this delivery modality. Thus, this study aimed to evaluate possible inflection points in cesarean rates in Brazil, its macro-regions, and federated units, as well as to estimate projections for 2030. A time series with information on cesarean sections from 1994 to 2019 from the SUS Department of Informatics was used. Autoregressive integrated moving average and joinpoint regression models were used to obtain cesarean rate projections and trends, respectively. Caesarean rates showed a significant upward trend over the 26 study years at all levels of aggregation. On the other hand, when considering the formation of segments, a stabilization trend was observed both in the country and in the South and Midwest regions, starting in 2012. Rates tended to increase in North and Northeast and significantly decrease in Southeast. Projections show that in 2030, 57.4% of births in Brazil will be cesarean, with rates higher than 70% in Southeast and South regions.

Satisfaction with childbirth care in Brazilian maternity hospitals participating in the Stork Network program: women's opinions.

This study aimed to describe maternal satisfaction with their experience during childbirth and birth and their association with sociodemographic, clinical and obstetric, and good practice characteristics during childbirth care. The sample included 2,069 women who wanted to express their opinions at the end of the interview of the Stork Network Assessment survey. Exploratory factor analysis was performed to summarize the variables of interest, creating latent variables, for input in the multiple logistic regression model. Six factors were created and tested in the model. Respect for the puerperal women was associated with satisfaction (vaginal delivery: 1.40; cesarean section: 1.47). Regarding those who underwent a cesarean section, satisfaction was associated with living in the Central-West (1.91) and South (2.00) regions and the presence of a companion during hospitalization (1.25). However, for women who had vaginal delivery, satisfaction was inversely associated with large hospitals (0.62) and undergoing interventions during labor and delivery (0.83), but positively with multiparity (1.98), receiving good care practices for labor and delivery (1.24), and having immediate contact with the newborn (1.20). The better understanding of the factors associated with mothers' care satisfaction for labor and delivery can improve care quality provided in public hospitals in the Brazil.

Baby-Friendly Hospital Initiative and exclusive breastfeeding during hospital stay.

OBJECTIVE: To estimate the prevalence of exclusive breastfeeding during maternity hospital stay (outcome) and to analyze the association between delivery in a Baby-Friendly Hospital (BFH) and the outcome. The hypothesis is that accreditation to this program improves exclusive breastfeeding during maternity hospital stay. Exclusive breastfeeding is essential in reducing neonatal morbidity and mortality. METHODS: This study is based on secondary data collected by the "Birth in Brazil: National Survey into Labour and Birth", a population-based study, conducted with 21,086 postpartum women, from February 1, 2011, to October 31, 2012, in 266 hospitals from all five Brazilian regions. Face-to-face interviews were conducted mostly within the first 24 hours after birth, regarding individual and gestational characteristics, prenatal care, delivery, newborn's characteristics, and breastfeeding at birth. A theoretical model was created, allocating the exposure variables in three levels based on their proximity to the outcome. This hierarchical conceptual model was applied to perform a multiple logistic regression (with 95%CI and p < 0.05). RESULTS: In this study, 76.0% of the babies were exclusively breastfed from birth until the interview. Babies born in public (AOR = 1.73; 95%CI: 1.10-2.87), mixed (AOR = 2.48; 95%CI: 1.35-4.53) and private (AOR = 5.54; 95%CI: 2.38-12.45) BFHs were more likely to be exclusively breastfed during maternity hospital stay than those born in non-BFHs, as well as those born by vaginal birth (AOR = 2.16; 95%CI: 1.79-2.61), with adolescent mothers (AOR = 1.83; 95%CI: 1.47-2.26) or adults up to 34 years old (AOR =1 .31; 95%CI: 1.13-1.52), primiparous women (AOR = 1.51; 95%CI: 1.34-1.70), and mothers living in the Northern region of Brazil (AOR = 1.99; 95%CI: 1.14-3.49). CONCLUSIONS: The Baby-Friendly Hospital Initiative promotes exclusive breastfeeding during hospital stay regarding individual and hospital differences.

Agreement between maternal self-report of birth-related information and medical records in Brazil: A comparison study between public, mixed, and private hospitals.

BACKGROUND: The study aims to assess agreement between data obtained from interviews with postpartum women and their health records about labor and birth characteristics, newborn care, and reasons for cesarean birth. METHODS: The present study analyzes the Birth in Brazil study dataset, a nationwide hospital-based survey that included 23,894 postpartum women. Reliability was assessed using kappa coefficients and 95% confidence intervals. We also calculated the proportion of specific agreement: the observed proportion of positive agreement (Ppos) and the observed proportion of negative agreement (Pneg). RESULTS: In terms of labor and birth characteristics, more significant discrepancies in prevalence were observed for fundal pressure (1.4%-42.6%), followed by amniotomy, and augmentation. All of these variables were reported more frequently by women. Reliability was nearly perfect only for mode of delivery (kappa 0.99-1.00, Ppos and Pneg >99.0%). Higher discrepancies in reasons for cesarean prevalence were observed for previous cesarean birth (CB) (3.9%-10.4%) and diabetes mellitus (0.5%-8.5%). Most kappa coefficients for CB reasons were moderate to substantial. Lower coefficients were seen for diabetes mellitus, induction failure, and prelabor rupture of membranes and Pneg was consistently higher than Ppos. DISCUSSION: Our findings raise relevant questions about the quality of information shared with women during and after the process of care for labor and birth, as well as the information recorded in medical charts. Not having access to full information about their own health status at birth may impair women's health promotion behaviors or clear disclosure of risk factors in future interactions with the healthcare system.

[Good practices, interventions, and results: a comparative study between a birthing center and hospitals of the Brazilian Unified National Health System in the Southeastern Region, Brazil]. / Boas práticas, intervenções e resultados: um estudo comparativo entre uma casa de parto e hospitais do Sistema Único de Saúde da Região Sudeste, Brasil.

This study aims to compare obstetric care in a birthing center and in hospitals of the Brazilian Unified National Health System (SUS) considering good practices, interventions, and maternal and perinatal results in the Southeast Region of Brazil. A cross-sectional study was conducted with comparable retrospective data from two studies on labor and birth. A total of 1,515 puerperal women of usual risk of birthing centers and public hospitals in the Southeast region were included. Propensity score weighting was used to balance the groups according to the following covariates: age, skin-color, parity, membrane integrity, and cervix dilation at hospitalization. Logistic regressions were used to estimate odds ratios (OR) and 95% confidence intervals (95%CI) between the place of birth and outcomes. In birthing centers, compared to hospitals, the puerperal woman had a higher chance of having a companion (OR = 86.31; 95%CI: 29.65-251.29), eating or drinking (OR = 862.38; 95%CI: 120.20-6,187.33), walking around (OR = 7.56; 95%CI: 4.65-12.31), using non-pharmacological methods for pain relief (OR = 27.82; 95%CI: 17.05-45.40), being in an upright position (OR = 252.78; 95%CI: 150.60-423.33), and a lower chance of using oxytocin (OR = 0.22; 95%CI: 0.16-0.31), amniotomy (OR = 0.01; 95%CI: 0.01-0.04), episiotomy (OR = 0.01; 95%CI: 0.00-0.02), and Kristeller maneuvers (OR = 0.01; 95%CI: 0.00-0.02). Also, in birthing centers the newborn had a higher chance of exclusive breastfeeding (OR = 1.84; 95%CI: 1.16-2.90) and a lower chance of airway (OR = 0.24; 95%CI: 0.18-0.33) and gastric aspiration (OR = 0.15; 95%: 0.10-0.22). Thus, birthing centers offers a greater supply of good practices and fewer interventions in childbirth and birth care, with more safety and care without influence on the outcomes.

O objetivo deste estudo foi comparar a assistência obstétrica em uma casa de parto e em hospitais do Sistema Único de Saúde (SUS) da Região Sudeste do Brasil, considerando boas práticas, intervenções e resultados maternos e perinatais. Realizou-se um estudo transversal com dados retrospectivos comparáveis, provenientes de dois estudos sobre parto e nascimento, e amostra de 1.515 puérperas de risco habitual de uma casa de parto e hospitais públicos da Região Sudeste. Utilizou-se ponderação pelo escore de propensão para equilibrar os grupos de acordo com as covariáveis idade, raça, paridade, integridade das membranas e dilatação do colo na internação, bem como regressões logísticas para estimar razões de chance (OR) e intervalos de 95% de confiança (IC95%) entre o local de parto e desfechos. Na casa de parto, quando comparada ao hospital, as puérperas tiveram maior chance de ter acompanhante (OR = 86,31; IC95%: 29,65-251,29), se alimentar ou tomar líquidos (OR = 862,38; IC95%: 120,20-6.187,33), se movimentar (OR = 7,56; IC95%: 4,65-12,31), usar métodos não farmacológicos para alívio da dor (OR = 27,82; IC95%: 17,05-45,40) e posição verticalizada (OR = 252,78; IC95%: 150,60-423,33) e menor chance de utilizar ocitocina (OR = 0,22; IC95%: 0,16-0,31), amniotomia (OR = 0,01; IC95%: 0,01-0,04), episiotomia (OR = 0,01; IC95%: 0,00-0,02) e manobra de Kristeller (OR = 0,01; IC95%: 0,00-0,02). Ademais, na casa de parto os recém-nascidos tiveram maior chance de aleitamento exclusivo (OR = 1,84; IC95%: 1,16-2,90) e menor chance de aspiração de vias aéreas (OR = 0,24; IC95%: 0,18-0,33) e gástrica (OR = 0,15; IC95%: 0,10-0,22). A casa de parto apresenta, assim, maior oferta de boas práticas e menos intervenções na assistência ao parto e nascimento, com segurança e cuidado, sem afetar os resultados.

El objetivo de este estudio fue comparar la asistencia obstétrica entre una clínica de parto y hospitales del Sistema Único de Salud (SUS) en la región Sudeste de Brasil, teniendo en cuenta las buenas prácticas, intervenciones y resultados maternos y perinatales. Se llevó a cabo un estudio transversal con datos retrospectivos comparables de dos estudios sobre trabajo de parto y nacimiento. La muestra se compuso de 1.515 puérperas con riesgo habitual en una clínica de parto y en hospitales públicos de la región Sudeste. Se utilizó la ponderación del puntaje de propensión para equilibrar los grupos según las siguientes covariables: edad, color de la piel, paridad, integridad de las membranas y dilatación cervical en la hospitalización. La regresión logística se utilizó para estimar la razón de posibilidades (OR), y se aplicó el intervalo del 95% de confianza (IC95%) entre el lugar de parto y desenlace. En la clínica de parto en comparación con el hospital, la puérpera tenía más posibilidades de tener un acompañante (OR = 86,31; IC95%: 29,65-251,29), comer o beber líquidos (OR = 862,38; IC95%: 120,20-6.187,33), moverse (OR = 7,56; IC95%: 4,65-12,31), utilizar métodos no farmacológicos para aliviar el dolor (OR = 27,82; IC95%: 17,05-45,40), posición erguida (OR = 252,78; IC95%: 150,60-423,33), y menor posibilidad de usar oxitocina (OR = 0,22; IC95%: 0,16-0,31), amniotomía (OR = 0,01; IC95%: 0,01-0,04), episiotomía (OR = 0,01; IC95%: 0,00-0,02) y maniobras de Kristeller (OR = 0,01; IC95%: 0,00-0,02). Los recién nacidos tenían más posibilidades de recibir una lactancia exclusiva (OR = 1,84; IC95%: 1,16-2,90) y menos posibilidades de tener aspiración de vía aérea (OR = 0,24; IC95%: 0,18-0,33) y gástrica (OR = 0,15; IC95%: 0,10-0,22). La clínica de parto cuenta con una mayor oferta de buenas prácticas y menos intervenciones en la asistencia al parto y nacimiento, con seguridad y cuidado, sin afectar los resultados.

Influence of mode of delivery on satisfaction with hospitalization for childbirth in the study Birth in Brazil.

Controversial results have been reported on the association between mode of delivery and patient satisfaction. This study investigates which mode of delivery leads to greater satisfaction with hospital admission for childbirth. A cohort study was conducted with data from the Birth in Brazil study, which began in 2011. A total of 23,046 postpartum women were included from a random sample of hospitals, selected by conglomerates with a three level stratification. At the first follow-up, 15,582 women were re-interviewed. Mode of delivery, dichotomized into vaginal or cesarean section, and confounders were collected before hospital discharge. The outcome maternal satisfaction, investigated as a 10-item unidimensional construct, was measured by the Hospital Birth Satisfaction Scale up to six months after discharge. We used a directed acyclic graph to define minimal adjustment variables for confounding. The effect of mode of delivery on satisfaction was estimated using a structural equation model with weighting by the inverse of the probability of selection, considering the complex sampling design. The weight was estimated considering the different sample selection probabilities, the losses to follow-up, and the propensity score, which was estimated in a logistic regression model. The analysis revealed no significant difference in satisfaction with hospitalization for childbirth between respondents who had vaginal delivery and cesarean section in the adjusted analysis (standardized coefficient = 0.089; p-value = 0.056). Therefore, women who had vaginal delivery and cesarean section were equally satisfied with their hospitalization for childbirth.

The effect of obstetric violence during childbirth on breastfeeding: findings from a perinatal cohort "Birth in Brazil".

Background: Recent literature has shown that many women worldwide are victims of obstetric violence during childbirth. Despite that, few studies are exploring the consequences of such violence on women's and newborn's health. Thus, the present study aimed to investigate the causal association between obstetric violence during childbirth and breastfeeding. Methods: We used data from the study "Birth in Brazil", a national hospital-based cohort of puerperal women and their newborns in 2011/2012. The analysis involved 20,527 women. Obstetric violence was a latent variable composed of seven indicators (physical or psychological violence, disrespect, lack of information, privacy and communication with the healthcare team, inability to ask questions, and loss of autonomy). We worked with two outcomes: 1) breastfeeding at the maternity and 2) breastfeeding 43-180 days after birth. We applied multigroup structural equation modelling, based on the type of birth. Findings: Obstetric violence during childbirth may decrease the probability for women to leave the maternity ward breastfeeding exclusively, having a stronger effect on women who have vaginal birth. Also, being exposed to obstetric violence during childbirth could indirectly affect those women's ability to breastfeed 43-180 days after birth. Interpretation: This research concludes that obstetric violence during childbirth is a risk factor for breastfeeding discontinuation. Such knowledge is relevant so interventions and public policies can be proposed in order to mitigate obstetric violence and provide a better understanding of the context that may lead a woman into discontinuing breastfeeding. Funding: This research was funded by CAPES, CNPQ, DeCiT, and INOVA-ENSP.

Growth Velocity and Nutritional Status in Children Exposed to Zika Virus during Pregnancy from Amazonas Cohort, Brazil.

The high incidence of Zika virus (ZIKV) infection in the period of 2015-2016 in Brazil may have affected linear height growth velocity (GV) in children exposed in utero to ZIKV. This study describes the growth velocity and nutritional status based on the World Organization (WHO) standards of children exposed to ZIKV during pregnancy and followed up in a tertiary unit, a reference for tropical and infectious diseases in the Amazon. Seventy-one children born between March 2016 and June 2018 were monitored for anthropometric indices: z-score for body mass index (BMI/A); weight (W/A); height (H/A) and head circumference (HC/A); and growth velocity. The mean age at the last assessment was 21.1 months (SD ± 8.93). Four children had congenital microcephaly and severe neurological impairment. The other 67 were non-microcephalic children (60 normocephalic and 7 macrocephalic); of these; 24.2% (16 children) had neurological alterations, and 28.8% (19 children) had altered neuropsychomotor development. Seventeen (24.2%) children had inadequate GV (low growth velocity). The frequencies of low growth among microcephalic and non-microcephalic patients are 25% (1 of 4 children) and 23.9% (16 of 67 children); respectively. Most children had normal BMI/A values during follow-up. Microcephalic patients showed low H/A and HC/A throughout the follow-up, with a significant reduction in the HC/A z-score. Non-microcephalic individuals are within the regular ranges for H/A; HC/A; and W/A, except for the H/A score for boys. This study showed low growth velocity in children with and without microcephaly, highlighting the need for continuous evaluation of all children born to mothers exposed to ZIKV during pregnancy.

Impact of an intrapartum care quality improvement intervention in Brazilian private hospitals on care safety measures and adverse outcomes.

BACKGROUND: In 2015, a quality improvement (QI) intervention to reduce cesarean sections (CS)-the Adequate Childbirth Project (PPA)-was implemented in the private sector in Brazil. This analysis aims to compare safety care measures and adverse outcomes between women exposed to the PPA intervention to those receiving standard care. METHODS: The analysis included a convenience sample of 12 private hospitals that participated in the PPA (2017-2018). Data collection was performed through chart review and interviews. Differences in 15 outcomes were examined using Pearson's chi-square test and multiple logistic regressions. RESULTS: The final weighted sample was comprised of 4789 births, 2570 in the PPA group (53.5%) and 2227 in the standard care group (46.5%). CS rate was significantly lower in the PPA group (67.3% vs 88.8%). After adjusting for potential confounders, PPA model was associated with decreased overall CS rate (OR = 0.30, 95% CI 0.24 to 0.36), as well as prelabor (OR = 0.41, 0.34 to 0.48) and repeated CS (OR = 0.45, 0.29 to 0.70). In terms of other safety care measures, women in the PPA model had an increased chance of absence of antibiotic prophylaxis in Group B Streptococcus (GBS) + women (OR = 4.63, 1.33 to 16.14) and for CSs (OR = 1.75, 1.38 to 2.22), while those with severe hypertension were less likely to not receiving magnesium sulphate (OR = 0.27, 0.09 to 0.77). Regarding obstetric and neonatal outcomes, PPA model was associated with a decreased chance of having an obstetric anal sphincter injury (OASI) following an episiotomy (OR = 0.34, 0.13 to 0.89), requiring antibiotics other than routine prophylaxis (OR = 0.84, 0.70 to 0.99), having a late preterm (OR = 0.36, 0.27 to 0.48) or early term baby (OR = 0.81, 0.70 to 0.94). There were no statistically significant differences for other outcomes. CONCLUSIONS: The PPA intervention was able to reduce CS rates, late preterm and early term deliveries without increasing the chance of adverse outcomes. The bidirectional effect on safety care measures reinforces that QI initiatives includes closer observation of routine care when implementing interventions to reduce C-section rates.

Cesarean section rates in Brazil are among the highest in the world, particularly in private hospitals. In 2015, a quality improvement project was implemented in private hospitals aiming to reduce the cesarean section (CS) rates (the Adequate Childbirth Project­PPA). In the 2017­2018 period, the Healthy Birth Study (HBS) was proposed to assess the effect of the PPA project in CS rates, as well as use of obstetric interventions, adoption of good practices during labor and birth care and outcomes for both women and their babies. This article presents the comparison of 4873 births analyzed in the HBS, 2589 who were exposed to the PPA project and 2284 who received standard care. The analysis aim was to compare CS rates at the same time to assess if women who were part of the PPA intervention were less likely to have a negative event for themselves or their babies. A group of 15 measures of safety of obstetric care and negative outcomes for women and their babies was compared. Women who were exposed to the PPA intervention had a lower chance of CS, late preterm and early term deliveries. At the same time, the PPA group did not have worse outcomes for women or babies. In terms of safety care, the PPA intervention was associated with both positive and negative effects. For instance, women exposed to the PPA group had a higher chance of not receiving antibiotics to prevent infections when they needed, when compared to standard care.

Breastfeeding in the first hour of life in Brazilian private hospitals participating in a quality-of-care improvement project.

BACKGROUND: The Baby-Friendly Hospital Initiative's Step 4 recommends: "support mothers to start breastfeeding as soon as possible after birth", thus contributing to the reduction of neonatal mortality. The objective of this study is to estimate the prevalence of breastfeeding in the first hour of life in private maternity hospitals participating in the "Adequate Childbirth Project", a quality-of-care improvement project, and to analyze determinants of this outcome. METHODS: Secondary analysis of data collected by the cross-sectional evaluative "Healthy Birth Study", conducted in 2017 in 12 maternity hospitals participating in the Adequate Childbirth Project, where 4800 mothers were interviewed, and hospital records were observed. Conditions that prevented breastfeeding at birth, such as maternal HIV-infection and newborns' severe malformations, were excluded. Multiple logistic regression was performed according to a hierarchical theoretical model. RESULTS: The prevalence of breastfeeding in the first hour of life was 58% (CI 95% 56.6-59.5%). Lower maternal education (aOR 0.643; CI 95% 0.528-0.782), lower economic status (aOR 0.687; CI 95% 0.504-0.935), cesarean section delivery (ORa 0.649; CI 95% 0.529-0.797), preterm birth (aOR 0.660; CI 95% 0.460-0.948) and non-rooming-in at birth (aOR 0.669; CI 95% 0.559-0.800) were negatively associated with the outcome. Receiving information during prenatal care about the importance of breastfeeding at birth (aOR 2.585; CI 95% 2.102-3.179), being target of the quality-of-care improvement project (aOR 1.273; CI 95% 1.065-1.522), skin-to-skin contact at birth (aOR 2.127; CI 95% 1.791-2.525) and female newborn (aOR 1.194; CI 95% 1.008-1.415) were factors positively associated with the outcome. CONCLUSIONS: The private maternities participating in the Healthy Birth Study showed a good prevalence of breastfeeding in the first hour of life, according to WHO parameters. Prenatal guidance on breastfeeding at birth, being target of the quality-of-care improvement project and skin-to-skin contact at birth contributed to breastfeeding in the first hour of life.

Evaluation of labor and childbirth care by nurse-midwives in Brazilian private hospitals: results of a quality improvement project.

BACKGROUND: In 2015, a quality improvement project-the "Adequate Childbirth Project" (Projeto Parto Adequado, or PPA)-was implemented in Brazilian private hospitals with the goal of reducing unnecessary cesarean sections. One of the strategies adopted by the PPA was the implementation of labor and childbirth care by nurse-midwives. The objective of this study is to evaluate the results of the PPA in the implementation and adequacy of labor and childbirth care by nurse-midwives in Brazilian private hospitals. METHODS: Cross-sectional, hospital-based study, carried out in 2017, in 12 hospitals participating in the PPA. We assessed the proportion of women assisted by nurse-midwives during labor and childbirth care and the adequacy of 13 care practices following parameters of the World Health Organization. Women assisted in the PPA model of care and in the standard of care model were compared using the chi-square statistical test. RESULTS: 4798 women were interviewed. Women in the PPA model of care had a higher proportion of labor (53% × 24.2%, p value < 0.001) and vaginal birth (32.7% × 11.3%, p value < 0.001), but no significant differences were observed in the proportion of women assisted by nurse-midwives during labor (54.8% × 50.1%, p value = 0.191) and vaginal birth (2.2% × 0.7%, p value = 0.142). The implementation of recommended practices was adequate, except the use of epidural analgesia for pain relief, which was intermediate. There was a greater use of recommended practices including "oral fluid and food", "maternal mobility and position", "monitoring of labor", "use of non-pharmacological methods for pain relief" and "epidural analgesia for pain relief" in women assisted by nurse-midwives in relation to those assisted only by doctors. Many non-recommended practices were frequently used during labor by nurse-midwives and doctors. CONCLUSIONS: There was an increase in the proportion of women with labor and vaginal birth in the PPA model of care and an appropriate use of recommended practices in women assisted by nurse-midwives. However, there was no difference in the proportion of women assisted by nurse-midwives in the two models of care. The expansion of nursing participation and the reduction of overused practices remain challenges.

Brazil has a high rate of cesarean sections with low participation of nurse-midwives in childbirth care. Nurse-midwife care is associated with less use of interventions, lower proportions of cesarean sections and greater women's satisfaction. In 2015, a quality improvement project, called the "Adequate Childbirth Project" (Projeto Parto Adequado, PPA), was implemented in Brazilian private hospitals to reduce unnecessary cesarean sections. One of its components is the expansion of nurse-midwives in labor and childbirth care. In this study, we evaluated the results of PPA on childbirth care by nurse-midwives. Data were collected in 12 hospitals with interviews with 4798 women. Women assisted in the PPA model of care had a higher proportion of labor and vaginal birth, but there was no increase in the proportion of women assisted by nurse-midwives, neither during labor nor vaginal birth. The use of recommended practices was adequate, except for the use of epidural analgesia, with greater use of some recommended practices in women assisted by nurse-midwives compared to those seen only by doctors. However, we observed excessive use of non-recommended practices during labor, both by doctors and nurses. We can conclude that there was an increase in the proportion of women with labor and vaginal birth in the PPA model of care and a greater use of recommended practices in women assisted by nurse-midwives, but without an increase in the proportion of women assisted by nurses. The expansion of nurse-midwives' participation in childbirth care and the reduction of non-recommended practices therefore continue to be challenges.

Satisfaction with childbirth care in Brazilian maternity hospitals participating in the Stork Network program: women's opinions / Satisfação com a assistência ao parto em maternidades brasileiras que participam da Rede Cegonha: opinião das mulheres / Satisfacción con la atención del parto en maternidades brasileñas que participan de la Red Cigüeña: la opinión de las mujeres

This study aimed to describe maternal satisfaction with their experience during childbirth and birth and their association with sociodemographic, clinical and obstetric, and good practice characteristics during childbirth care. The sample included 2,069 women who wanted to express their opinions at the end of the interview of the Stork Network Assessment survey. Exploratory factor analysis was performed to summarize the variables of interest, creating latent variables, for input in the multiple logistic regression model. Six factors were created and tested in the model. Respect for the puerperal women was associated with satisfaction (vaginal delivery: 1.40; cesarean section: 1.47). Regarding those who underwent a cesarean section, satisfaction was associated with living in the Central-West (1.91) and South (2.00) regions and the presence of a companion during hospitalization (1.25). However, for women who had vaginal delivery, satisfaction was inversely associated with large hospitals (0.62) and undergoing interventions during labor and delivery (0.83), but positively with multiparity (1.98), receiving good care practices for labor and delivery (1.24), and having immediate contact with the newborn (1.20). The better understanding of the factors associated with mothers' care satisfaction for labor and delivery can improve care quality provided in public hospitals in the Brazil.

Este estudo descreve a satisfação das mães com sua experiência no atendimento ao parto e nascimento de seus filhos e sua associação com características sociodemográficas, clínico-obstétricas e de boas práticas durante a assistência ao parto. A amostra incluiu 2.069 mulheres que expressaram sua opinião ao final da pesquisa Avaliação da Rede Cegonha. Foi realizada uma análise fatorial exploratória para resumir as variáveis de interesse, criando variáveis latentes para serem incluídas no modelo de regressão logística múltipla. Seis fatores foram criados e testados no modelo. O respeito pela puérpera foi associado à satisfação (parto vaginal: 1,40; parto cesáreo: 1,47). Para as mães que passaram por cesariana, houve associação com morar nas regiões Centro-oeste (1,91) e Sul (2,00) e com a presença de um acompanhante durante a internação (1,25). Para mulheres que tiveram parto vaginal, a satisfação foi inversamente associada a hospitais grandes (0,62) e à realização de intervenções durante o trabalho de parto e nascimento (0,83). A satisfação foi positivamente associada à multiparidade (1,98), recebimento de boas práticas de assistência durante o trabalho de parto e nascimento (1,24) e contato com o bebê logo após o nascimento (1,20). A melhor compreensão sobre os fatores associados à satisfação das mães com a assistência no trabalho de parto e nascimento pode contribuir para a qualidade do serviço prestado em hospitais públicos no país.

Se realizó un análisis factorial exploratorio para resumir las variables de interés, creando variables latentes para ser incluidas en el modelo de regresión logística múltiple. En el modelo se crearon y probaron seis factores. El respeto por la puérpera se asoció con la satisfacción (parto vaginal: 1,40; parto por cesárea: 1,47). Para las madres sometidas a cesárea, hubo asociación con vivir en las regiones Centro-oeste (1,91) y Sur (2,00) y con la presencia de un acompañante durante la hospitalización (1,25). Para las mujeres que tuvieron parto vaginal, la satisfacción fue inversamente asociada a hospitales grandes (0,62) y a la realización de intervenciones durante el trabajo de parto y nacimiento (0,83). La satisfacción se asoció positivamente con la multiparidad (1,98), recibir buenas prácticas de cuidado durante el trabajo de parto y el nacimiento (1,24) y el contacto con el bebé poco después del nacimiento (1,20). Una mejor comprensión sobre los factores asociados a la satisfacción de las madres con la asistencia en el trabajo de parto y nacimiento puede contribuir para la calidad del servicio prestado en hospitales públicos en el país.

Baby-Friendly Hospital Initiative and exclusive breastfeeding during hospital stay

ABSTRACT OBJECTIVE To estimate the prevalence of exclusive breastfeeding during maternity hospital stay (outcome) and to analyze the association between delivery in a Baby-Friendly Hospital (BFH) and the outcome. The hypothesis is that accreditation to this program improves exclusive breastfeeding during maternity hospital stay. Exclusive breastfeeding is essential in reducing neonatal morbidity and mortality. METHODS This study is based on secondary data collected by the "Birth in Brazil: National Survey into Labour and Birth", a population-based study, conducted with 21,086 postpartum women, from February 1, 2011, to October 31, 2012, in 266 hospitals from all five Brazilian regions. Face-to-face interviews were conducted mostly within the first 24 hours after birth, regarding individual and gestational characteristics, prenatal care, delivery, newborn's characteristics, and breastfeeding at birth. A theoretical model was created, allocating the exposure variables in three levels based on their proximity to the outcome. This hierarchical conceptual model was applied to perform a multiple logistic regression (with 95%CI and p < 0.05). RESULTS In this study, 76.0% of the babies were exclusively breastfed from birth until the interview. Babies born in public (AOR = 1.73; 95%CI: 1.10-2.87), mixed (AOR = 2.48; 95%CI: 1.35-4.53) and private (AOR = 5.54; 95%CI: 2.38-12.45) BFHs were more likely to be exclusively breastfed during maternity hospital stay than those born in non-BFHs, as well as those born by vaginal birth (AOR = 2.16; 95%CI: 1.79-2.61), with adolescent mothers (AOR = 1.83; 95%CI: 1.47-2.26) or adults up to 34 years old (AOR =1 .31; 95%CI: 1.13-1.52), primiparous women (AOR = 1.51; 95%CI: 1.34-1.70), and mothers living in the Northern region of Brazil (AOR = 1.99; 95%CI: 1.14-3.49). CONCLUSIONS The Baby-Friendly Hospital Initiative promotes exclusive breastfeeding during hospital stay regarding individual and hospital differences.

Influence of mode of delivery on satisfaction with hospitalization for childbirth in the study Birth in Brazil / Influência do tipo de parto na satisfação com a internação para o parto na pesquisa Nascer no Brasil / Influencia del tipo de parto en la satisfacción con la hospitalización para el parto en la encuesta Nacer en Brasil

Controversial results have been reported on the association between mode of delivery and patient satisfaction. This study investigates which mode of delivery leads to greater satisfaction with hospital admission for childbirth. A cohort study was conducted with data from the Birth in Brazil study, which began in 2011. A total of 23,046 postpartum women were included from a random sample of hospitals, selected by conglomerates with a three level stratification. At the first follow-up, 15,582 women were re-interviewed. Mode of delivery, dichotomized into vaginal or cesarean section, and confounders were collected before hospital discharge. The outcome maternal satisfaction, investigated as a 10-item unidimensional construct, was measured by the Hospital Birth Satisfaction Scale up to six months after discharge. We used a directed acyclic graph to define minimal adjustment variables for confounding. The effect of mode of delivery on satisfaction was estimated using a structural equation model with weighting by the inverse of the probability of selection, considering the complex sampling design. The weight was estimated considering the different sample selection probabilities, the losses to follow-up, and the propensity score, which was estimated in a logistic regression model. The analysis revealed no significant difference in satisfaction with hospitalization for childbirth between respondents who had vaginal delivery and cesarean section in the adjusted analysis (standardized coefficient = 0.089; p-value = 0.056). Therefore, women who had vaginal delivery and cesarean section were equally satisfied with their hospitalization for childbirth.

Estudos mostram resultados controversos sobre a associação entre o tipo de parto e a satisfação da paciente. Este estudo investiga qual tipo de parto traz maior satisfação com a internação hospitalar para o parto. Foi realizado um estudo de coorte com dados da pesquisa Nascer no Brasil, iniciada em 2011. Foram incluídas 23.046 puérperas de uma amostra aleatória de hospitais, por conglomerados, com estratificação em três níveis. No primeiro seguimento, 15.582 mulheres foram reentrevistadas. Coletou-se antes da alta hospitalar dados sobre o tipo de parto, dicotomizado em vaginal e cesáreo, e fatores de confusão. O desfecho satisfação materna, avaliado como um construto unidimensional de 10 itens, foi mensurado pela Escala de Satisfação com a Hospitalização para o Parto até seis meses após a alta. As variáveis mínimas de ajuste para confusão foram definidas em um gráfico acíclico direcionado. O efeito do tipo de parto sobre a satisfação foi estimado em um modelo de equação estrutural com ponderação pelo inverso da probabilidade de seleção, considerando o desenho amostral complexo. A ponderação foi estimada considerando as diferentes probabilidades de seleção da amostra, as perdas de seguimento e o escore de propensão. O escore de propensão foi estimado em um modelo de regressão logística. Não houve diferenças na satisfação com a internação para o parto entre as entrevistadas que tiveram partos vaginais e cesáreos na análise ajustada (coeficiente padronizado = 0,089; p = 0,056). As mulheres que tiveram partos vaginais e cesáreos ficaram igualmente satisfeitas com a hospitalização para o parto.

Los estudios muestran resultados controvertidos en cuanto a la asociación entre el tipo de parto y la satisfacción de la paciente. Este estudio investiga qué tipo de parto presenta mayor satisfacción con la hospitalización para el parto. Se realizó un estudio de cohorte con los datos de la encuesta Nacer en Brasil, que había comenzado en 2011. Se incluyeron a 23.046 puérperas de una muestra aleatoria de hospitales, por conglomerados, con estratificación en tres niveles. En el primer seguimiento se volvió a entrevistar a 15.582 mujeres. Los datos sobre el tipo de parto, ya sea por cesárea o vaginal, y los factores de confusión se recogieron antes del alta hospitalaria. El resultado de satisfacción materna, evaluado como un constructo unidimensional de diez ítems, se midió con la Escala de Satisfacción con la Hospitalización por Parto hasta seis meses después del alta. Las variables de ajuste mínimo de confusión se definieron en un gráfico acíclico dirigido. El efecto del tipo de parto sobre la satisfacción se estimó en un modelo de ecuaciones estructurales ponderadas por la inversa de la probabilidad de selección, considerando el diseño de muestreo complejo. La ponderación se estimó con diferentes probabilidades de selección de la muestra, pérdidas de seguimiento y puntuación de propensión. La puntuación de propensión se estimó mediante el modelo de regresión logística. No hubo diferencias en la satisfacción con la hospitalización por parto entre las encuestadas que tuvieron partos vaginales o por cesárea en el análisis ajustado (coeficiente estandarizado = 0,089; p = 0,056). Tanto las mujeres que tuvieron partos vaginales como las que tuvieron por cesárea estaban igualmente satisfechas con su hospitalización por parto.

Boas práticas, intervenções e resultados: um estudo comparativo entre uma casa de parto e hospitais do Sistema Único de Saúde da Região Sudeste, Brasil / Good practices, interventions, and results: a comparative study between a birthing center and hospitals of the Brazilian Unified National Health System in the Southeastern Region, Brazil / Buenas prácticas, intervenciones y resultados: un estudio comparativo entre la clínica de parto y hospitales del Sistema Único de Salud en la región Sudeste, Brasil

O objetivo deste estudo foi comparar a assistência obstétrica em uma casa de parto e em hospitais do Sistema Único de Saúde (SUS) da Região Sudeste do Brasil, considerando boas práticas, intervenções e resultados maternos e perinatais. Realizou-se um estudo transversal com dados retrospectivos comparáveis, provenientes de dois estudos sobre parto e nascimento, e amostra de 1.515 puérperas de risco habitual de uma casa de parto e hospitais públicos da Região Sudeste. Utilizou-se ponderação pelo escore de propensão para equilibrar os grupos de acordo com as covariáveis idade, raça, paridade, integridade das membranas e dilatação do colo na internação, bem como regressões logísticas para estimar razões de chance (OR) e intervalos de 95% de confiança (IC95%) entre o local de parto e desfechos. Na casa de parto, quando comparada ao hospital, as puérperas tiveram maior chance de ter acompanhante (OR = 86,31; IC95%: 29,65-251,29), se alimentar ou tomar líquidos (OR = 862,38; IC95%: 120,20-6.187,33), se movimentar (OR = 7,56; IC95%: 4,65-12,31), usar métodos não farmacológicos para alívio da dor (OR = 27,82; IC95%: 17,05-45,40) e posição verticalizada (OR = 252,78; IC95%: 150,60-423,33) e menor chance de utilizar ocitocina (OR = 0,22; IC95%: 0,16-0,31), amniotomia (OR = 0,01; IC95%: 0,01-0,04), episiotomia (OR = 0,01; IC95%: 0,00-0,02) e manobra de Kristeller (OR = 0,01; IC95%: 0,00-0,02). Ademais, na casa de parto os recém-nascidos tiveram maior chance de aleitamento exclusivo (OR = 1,84; IC95%: 1,16-2,90) e menor chance de aspiração de vias aéreas (OR = 0,24; IC95%: 0,18-0,33) e gástrica (OR = 0,15; IC95%: 0,10-0,22). A casa de parto apresenta, assim, maior oferta de boas práticas e menos intervenções na assistência ao parto e nascimento, com segurança e cuidado, sem afetar os resultados.

This study aims to compare obstetric care in a birthing center and in hospitals of the Brazilian Unified National Health System (SUS) considering good practices, interventions, and maternal and perinatal results in the Southeast Region of Brazil. A cross-sectional study was conducted with comparable retrospective data from two studies on labor and birth. A total of 1,515 puerperal women of usual risk of birthing centers and public hospitals in the Southeast region were included. Propensity score weighting was used to balance the groups according to the following covariates: age, skin-color, parity, membrane integrity, and cervix dilation at hospitalization. Logistic regressions were used to estimate odds ratios (OR) and 95% confidence intervals (95%CI) between the place of birth and outcomes. In birthing centers, compared to hospitals, the puerperal woman had a higher chance of having a companion (OR = 86.31; 95%CI: 29.65-251.29), eating or drinking (OR = 862.38; 95%CI: 120.20-6,187.33), walking around (OR = 7.56; 95%CI: 4.65-12.31), using non-pharmacological methods for pain relief (OR = 27.82; 95%CI: 17.05-45.40), being in an upright position (OR = 252.78; 95%CI: 150.60-423.33), and a lower chance of using oxytocin (OR = 0.22; 95%CI: 0.16-0.31), amniotomy (OR = 0.01; 95%CI: 0.01-0.04), episiotomy (OR = 0.01; 95%CI: 0.00-0.02), and Kristeller maneuvers (OR = 0.01; 95%CI: 0.00-0.02). Also, in birthing centers the newborn had a higher chance of exclusive breastfeeding (OR = 1.84; 95%CI: 1.16-2.90) and a lower chance of airway (OR = 0.24; 95%CI: 0.18-0.33) and gastric aspiration (OR = 0.15; 95%: 0.10-0.22). Thus, birthing centers offers a greater supply of good practices and fewer interventions in childbirth and birth care, with more safety and care without influence on the outcomes.

La regresión logística se utilizó para estimar la razón de posibilidades (OR), y se aplicó el intervalo del 95% de confianza (IC95%) entre el lugar de parto y desenlace. En la clínica de parto en comparación con el hospital, la puérpera tenía más posibilidades de tener un acompañante (OR = 86,31; IC95%: 29,65-251,29), comer o beber líquidos (OR = 862,38; IC95%: 120,20-6.187,33), moverse (OR = 7,56; IC95%: 4,65-12,31), utilizar métodos no farmacológicos para aliviar el dolor (OR = 27,82; IC95%: 17,05-45,40), posición erguida (OR = 252,78; IC95%: 150,60-423,33), y menor posibilidad de usar oxitocina (OR = 0,22; IC95%: 0,16-0,31), amniotomía (OR = 0,01; IC95%: 0,01-0,04), episiotomía (OR = 0,01; IC95%: 0,00-0,02) y maniobras de Kristeller (OR = 0,01; IC95%: 0,00-0,02). Los recién nacidos tenían más posibilidades de recibir una lactancia exclusiva (OR = 1,84; IC95%: 1,16-2,90) y menos posibilidades de tener aspiración de vía aérea (OR = 0,24; IC95%: 0,18-0,33) y gástrica (OR = 0,15; IC95%: 0,10-0,22).

[Magnitude and characteristics of late-term and post-term births: analysis of maternal and neonatal complications in Brazil, 2011]. / Magnitude e características dos nascimentos termo tardio e pós-termo e complicações maternas e neonatais no Brasil, 2011.

This study analyzed late-term and post-term birth, evaluating the maternal profile, its characteristics, and maternal and neonatal complications. A total of 23,610 babies were selected from the Birth in Brazil study (2011), and a descriptive analysis of the study population was performed. The association between late-term and post-term birth and their outcomes was performed using logistic regressions (p-value < 0.05). The prevalence found was 7.4% for late-term and 2.5% for post-term birth, both of which were more frequent in the North and Northeast regions, in adolescents, black women, with low schooling, multiparous, cared for by the public sector. Late term pregnancies had a higher chance of induction of vaginal delivery (OR = 2.02; 95%CI: 1.67-2.45), of cesarean section (OR = 1.32; 95%CI: 1.16-1.52), of severe laceration (OR = 3.75; 95%CI: 1.36-10.36), and of oxygen therapy for newborns (OR = 1.52; 95%CI: 1.02-2.26). In post-term pregnancies, newborns had a lower chance of breastfeeding at birth (OR = 0.74; 95%CI: 0.56-0.97) and during hospitalization (OR = 0.62; 95%CI: 0.40-0.97) and a higher chance of being born small for the gestational age (OR = 4.01; 95%CI: 2.83-5.70). The results using only ultrasound as a measure of gestational age confirmed the previous findings. Late-term and post-term pregnancies occur more frequently in the North and Northeast regions and in women with greater social vulnerability, being associated with maternal and neonatal complications.

Este estudo analisou o nascimento termo tardio e pós-termo, avaliando o perfil materno, suas características e as complicações maternas e neonatais. Foram selecionados 23.610 bebês do estudo Nascer no Brasil (2011), sendo realizada uma análise descritiva da população de estudo. A associação entre o nascimento termo tardio e pós-termo e seus desfechos foi efetuada pela utilização de regressões logísticas (valor de p < 0,05). A prevalência encontrada foi de 7,4% para o termo tardio e de 2,5% para o pós-termo, tendo ambos sido mais frequentes nas regiões Norte e Nordeste, em adolescentes, mulheres negras, de baixa escolaridade, multíparas, atendidas no setor público. As gestações termo tardio tiveram maior chance de indução do parto vaginal (OR = 2,02; IC95%: 1,67-2,45), de cesariana (OR = 1,32; IC95%: 1,16-1,52), de laceração grave (OR = 3,75; IC95%: 1,36-10,36) e de uso oxigenoterapia para os recém-nascidos (OR = 1,52; IC95%: 1,02-2,26). Nas gestações pós-termo, os recém-nascidos tiveram menor chance de amamentação ao nascer (OR = 0,74; IC95%: 0,56-0,97) e durante a hospitalização (OR = 0,62; IC95%: 0,40-0,97) e maior chance de nascerem pequenos para a idade gestacional (OR = 4,01; IC95%: 2,83-5,70). Os resultados utilizando somente a ultrassonografia como medida da idade gestacional confirmaram os achados anteriores. Gestações termo tardio e pós-termo ocorrem com maior frequência nas regiões Norte e Nordeste e em mulheres com maior vulnerabilidade social, associando-se a complicações maternas e neonatais.

Este estudio analizó los nacimientos a término tardío y postérmino, evaluando el perfil materno, sus características y las complicaciones maternas y neonatales. Se seleccionó a 23.610 bebés del estudio Nacer en Brasil (2011) para realizar un análisis descriptivo de la población de estudio. La asociación entre el nacimiento a término tardío y postérmino y sus desenlaces se realizó mediante regresiones logísticas (valor de p < 0,05). Se encontró una prevalencia del 7,4% para nacimientos a término tardío y del 2,5% para postérmino, ambas más frecuentes en las regiones Norte y Nordeste brasileño, en adolescentes, mujeres negras, con bajo nivel de estudios, multíparas y atendidas en el sector público de salud. Los embarazos a término tardío tuvieron una mayor probabilidad de inducir el parto vaginal (OR = 2,02; IC95%: 1,67-2,45), cesárea (OR = 1,32; IC95%: 1,16-1,52), laceración severa (OR = 3,75; IC95%: 1,36-10,36) y uso de oxigenoterapia en los recién nacidos (OR = 1,52; IC95%: 1,02-2,26). En los embarazos postérmino, los recién nacidos tuvieron menos probabilidad de ser amamantados al nacer (OR = 0,74; IC95%: 0,56-0,97) y durante la hospitalización (OR = 0,62; IC95%: 0,40-0,97), y más probabilidad de nacer pequeños para la edad gestacional (OR = 4,01; IC95%: 2,83-5,70). Los resultados que utilizaron solo la ecografía como medición para la edad gestacional confirmaron estos hallazgos. Los embarazos a término tardío y postérmino ocurren con mayor frecuencia en las regiones Norte y Nordeste brasileño, en mujeres con mayor vulnerabilidad social y están asociados a complicaciones maternas y neonatales.

Variations in cesarean and repeated cesarean section rates in Brazil according to gestational age at birth and type of hospital. / Variações das taxas de cesariana e cesariana recorrente no Brasil segundo idade gestacional ao nascer e tipo de hospital.

This study aimed to describe cesarean and repeated cesarean section rates in Brazil according to gestational age (GA) at birth and type of hospital. This is an ecologic study using data from the Brazilian Information System on Live Births and the 2017 National Registry of Health Facilities. Overall and repeated cesarean section rates were calculated and analyzed according to GA, region of residence, and type of hospital. Spearman correlations were performed between cesarean and repeated cesarean section rates by GA subgroups at birth (≤ 33, 34-36, 37-38, 39-41, and ≥ 42 weeks) and analyzed according to the type of hospital. Overall and repeated cesarean section rates were 55.1% and 85.3%, respectively. More than 60% of newborns between 37-38 weeks were delivered via cesarean section. Private hospitals in all regions showed the highest cesarean section rates, especially those in the Central-West Region, with more than 80% at all GAs. The overall cesarean section rate was highly correlated with all cesarean section rates of GA subgroups (r > 0.7, p < 0.01). Regarding repeated cesarean sections, the overall rate was strongly correlated with the rates of 37-38 and 39-41 weeks in public/mixed hospitals, differing from private hospitals, which showed moderate correlations. This finding indicates the decision for cesarean section is not based on clinical factors, which can cause unnecessary damage to the health of both the mother and the baby. Then, changes in the delivery care model, strengthening public policies, and encouragement of vaginal delivery after a cesarean section in subsequent pregnancies are important strategies to reduce cesarean section rates in Brazil.

O objetivo deste estudo foi descrever as taxas de cesariana e cesariana recorrente no Brasil segundo a idade gestacional (IG) ao nascer e o tipo de hospital. Trata-se de um estudo ecológico, utilizando dados do Sistema de Informação sobre Nascidos Vivos e do Cadastro Nacional de Estabelecimentos de Saúde de 2017. As taxas de cesariana geral e recorrente foram calculadas e analisadas de acordo com a IG, região de residência e tipo de hospital. Foram realizadas correlações de Spearman entre as taxas de cesariana e cesariana recorrente por subgrupos de IG ao nascer (≤ 33, 34-36, 37-38, 39-41 e ≥ 42 semanas), analisadas segundo o tipo de hospital. Verificaram-se taxas de cesariana geral e recorrente de 55,1% e 85,3%, respectivamente. Mais de 60% dos recém-nascidos entre 37-38 semanas ocorreram via cesariana. Os hospitais privados de todas as regiões concentraram as maiores taxas de cesariana, sobretudo os do Centro-oeste, com mais de 80% em todas as IG. A taxa geral de cesariana foi altamente correlacionada com todas as taxas de cesariana dos subgrupos de IG (r > 0,7, p < 0,01). Quanto à cesariana recorrente, verificou-se forte correlação com as taxas de 37-38 e 39-41 semanas no hospital público/misto, diferindo do hospital privado, que apresentou correlações moderadas. Isso indica que a decisão pela cesariana não é pautada em fatores clínicos, o que pode causar danos desnecessários à saúde da mulher e do bebê. Conclui-se que mudanças no modelo de atenção ao parto, fortalecimento de políticas públicas e maior incentivo do parto vaginal após cesárea em gestações subsequentes são estratégias importantes para a redução das cesarianas no Brasil.

El objetivo de este estudio fue describir las tasas de cesárea y de cesárea recurrente en Brasil según la edad gestacional (EG) al nacer y el tipo de hospital. Estudio ecológico a partir de los datos del Sistema de Información de Nacidos Vivos y del Registro Nacional de Establecimientos de Salud 2017. Se calcularon y analizaron las tasas de cesárea general y recurrente según EG, región de residencia y tipo de hospital. Se aplicaron las correlaciones de Spearman entre las tasas de cesárea y de cesárea recurrente por subgrupos de EG al nacer (≤ 33, 34-36, 37-38, 39-41 y ≥ 42 semanas) y se analizaron según el tipo de hospital. Las tasas de cesárea general y recurrente fueron del 55,1% y 85,3%, respectivamente. Más del 60% de los recién nacidos entre 37-38 semanas nacieron por cesárea. Los hospitales privados de todas las regiones concentraron las tasas más altas de cesáreas, especialmente los del Centro-Oeste, con más del 80% en todas las EG. En general, la tasa general de cesáreas estuvo altamente correlacionada con todas las tasas de cesáreas de los subgrupos de EG (r > 0,7, p < 0,01). En cuanto a la cesárea recurrente, se encontró que la tasa general se correlacionó fuertemente con las tasas de 37-38 y 39-41 semanas en el hospital público/mixto, a diferencia del hospital privado que mostró correlaciones moderadas. Esto indica que la decisión de hacer la cesárea no se basa en factores clínicos, lo que puede causar daños innecesarios a la salud de la mujer y del bebé. Por lo tanto, los cambios en el modelo de asistencia al parto, el fortalecimiento de las políticas públicas y una mayor promoción del parto vaginal en los embarazos posteriores de la cesárea se encuentran entre las estrategias importantes para reducir esta práctica en Brasil.

Obstetric interventions in a maternity hospital with a collaborative model of care: a comparative observational study.

Collaborative models (CM) focused on intrapartum care shared between both midwives and obstetricians have been proposed as a strategy to reduce these rates. Our aim was to compare use of evidence-based practices, obstetric interventions and c-section rates in two settings: a maternity hospital that applies a CM of care (MRJ) and data from a pool of maternity hospitals included in the Birth in Brazil Survey (NB) that do not adopt a CM. Data was abstracted from medical and administrative records in MRJ and from medical records and face-to-face interviews in NB. Differences were compared using chi-square test, with significance level set at p<0.05. MRJ showed a higher frequency of labour companionship, labour care provided by nurse midwives, non-pharmacological pain relief methods, food intake during labour, and less use of oxytocin, analgesia and amniotomy. More women also had second stage assisted by a nurse midwife and in a vertical position, as well as lower use of episiotomies and vacuum-extractor/forceps. The c-section rate was lower at MRJ. Shared care between midwives and obstetricians can be an effective strategy to improve quality of intrapartum care.
