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.

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.

Associations between cesarean delivery and child mortality: A national record linkage longitudinal study of 17.8 million births in Brazil.

BACKGROUND: There is an increasing use of cesarean delivery (CD) based on preference rather than on medical indication. However, the extent to which nonmedically indicated CD benefits or harms child survival remains unclear. Our hypothesis was that in groups with a low indication for CD, this procedure would be associated with higher child mortality and in groups with a clear medical indication CD would be associated with improved child survival chances. METHODS AND FINDINGS: We conducted a population-based cohort study in Brazil by linking routine data on live births between January 1, 2012 and December 31, 2018 and assessing mortality up to 5 years of age. Women with a live birth who contributed records during this period were classified into one of 10 Robson groups based on their pregnancy and delivery characteristics. We used propensity scores to match CD with vaginal deliveries (1:1) and prelabor CD with unscheduled CD (1:1) and estimated associations with child mortality using Cox regressions. A total of 17,838,115 live births were analyzed. After propensity score matching (PSM), we found that live births to women in groups with low expected frequencies of CD (Robson groups 1 to 4) had a higher death rate up to age 5 years if they were born via CD compared with vaginal deliveries (HR = 1.25, 95% CI: 1.22 to 1.28; p < 0.001). The relative rate was greatest in the neonatal period (HR = 1.39, 95% CI: 1.34 to 1.45; p < 0.001). There was no difference in mortality rate when comparing offspring born by a prelabor CD to those born by unscheduled CD. For the live births to women with a CD in a prior pregnancy (Robson group 5), the relative rates for child mortality were similar for those born by CD compared with vaginal deliveries (HR = 1.05, 95% CI: 1.00 to 1.10; p = 0.024). In contrast, for live births to women in groups with high expected rates of CD (Robson groups 6 to 10), the child mortality rate was lower for CD than for vaginal deliveries (HR = 0.90, 95% CI: 0.89 to 0.91; p < 0.001), particularly in the neonatal period (HR = 0.84, 95% CI: 0.83 to 0.85; p < 0.001). Our results should be interpreted with caution in clinical practice, since relevant clinical data on CD indication were not available. CONCLUSIONS: In this study, we observed that in Robson groups with low expected frequencies of CD, this procedure was associated with a 25% increase in child mortality. However, in groups with high expected frequencies of CD, the findings suggest that clinically indicated CD is associated with a reduction in child mortality.

Evaluation of a quality improvement intervention for labour and birth care in Brazilian private hospitals: a protocol.

BACKGROUND: In Brazilian private hospitals, caesarean section (CS) is almost universal (88%) and is integrated into the model of birth care. A quality improvement intervention, "Adequate Birth" (PPA), based on four driving components (governance, participation of women and families, reorganisation of care, and monitoring), has been implemented to help 23 hospitals reduce their CS rate. This is a protocol designed to evaluate the implementation of PPA and its effectiveness at reducing CS as a primary outcome of birth care. METHODS: Case study of PPA intervention conducted in 2017/2018. We integrated quantitative and qualitative methods into data collection and analysis. For the quantitative stage, we selected a convenient sample of twelve hospitals. In each of these hospitals, we included 400 women. This resulted in a total sample of 4800 women. We used this sample to detect a 2.5% reduction in CS rate. We interviewed managers and puerperal women, and extracted data from hospital records. In the qualitative stage, we evaluated a subsample of eight hospitals by means of systematic observation and semi-structured interviews with managers, health professionals and women. We used specific forms for each of the four PPA driving components. Forms for managers and professionals addressed the decision-making process, implemented strategies, participatory process in strategy design, and healthcare practice. Forms for women and neonatal care addressed socio-economic, demographic and health condition; prenatal and birth care; tour of the hospital before delivery; labour expectation vs. real experience; and satisfaction with care received. We will estimate the degree of implementation of PPA strategies related to two of the four driving components: "participation of women and families" and "reorganisation of care". We will then assess its effect on CS rate and secondary outcomes for each of the twelve selected hospitals, and for the total sample. To allow for clinical, socio-demographic and obstetric characteristics in women, we will conduct multivariate analysis. Additionally, we will evaluate the influence of internal context variables (the PPA driving components "governance" and "monitoring") on the degree of implementation of the components "participation of women and families" and "reorganisation of care", by means of thematic content analysis. This analysis will include both quantitative and qualitative data. DISCUSSION: The effectiveness of quality improvement interventions that reduce CS rates requires examination. This study will identify strategies that could promote healthier births.

Regional and social inequalities in the performance of Pap test and screening mammography and their correlation with lifestyle: Brazilian national health survey, 2013.

BACKGROUND: Mass population screening for the early detection of cervical and breast cancer has been shown to be a safe and effective strategy worldwide and has reduced the incidence and mortality rates of these diseases. The aim of this study is to analyse the reach of screening tests for cervical and breast cancer according to sociodemographic variables and to analyse their correlation with a healthy lifestyle. METHODS: We have analysed data collected from 31.845 women aged 18 and over, who were interviewed for the Brazilian National Health Survey, a nationwide household inquiry, which took place between August 2013 and February 2014. The Pap tests performed in the last 3 years in women aged between 25 and 64 and screening mammogram performed in the last 2 years in women aged between 50 and 69 were considered adequate. We identified habits that constitute a healthy lifestyle, such as the consumption of five or more daily servings of fruits and vegetables, 30 min or more of leisurely physical activity and not smoking. RESULTS: We observed that the Pap test (78.8 %) was more widespread than the screening mammogram (54.5 %), with significant geographical and social differences concerning access to health care. Access for such screening was higher for women living in more developed regions (Southeast and South), who were white-skinned, better educated, living with a partner and, especially, who were covered by private health insurance. Those who underwent the tests according to established protocols also had a healthy lifestyle, which corroborates the healthy behaviour pattern of damage prevention. CONCLUSION: Despite the progress made, social disparity still defines access to screening tests for cervical and breast cancer, with women covered by private health insurance tending to benefit the most. It is necessary to reduce social and regional inequalities and ensure a more uniform provision and access to the tests, especially for socially disadvantaged women, in order to reduce the incidence and mortality rate resulting from the aforementioned diseases.

Determinants of gestational night blindness in pregnant women from Rio de Janeiro, Brazil.

OBJECTIVE: To describe the prevalence and determinants of gestational night blindness in pregnant women receiving care in a hospital in Rio de Janeiro, Brazil. DESIGN: Cross-sectional study of pregnant and postpartum women receiving care in a public hospital in Rio de Janeiro from 1999 to 2001 (group I; n 225) or from 2005 to 2008 (group II; n 381). Night blindness was identified through a standardized and validated interview (WHO, 1996). The determinants of gestational night blindness were identified through a hierarchical logistic regression model. SETTING: Public maternity hospital in Rio de Janeiro, RJ, Brazil. SUBJECTS: Adult pregnant and postpartum women (n 606), aged ≥20 years. RESULTS: The prevalence of gestational night blindness was 9·9 %. The final model revealed that not living in the South Zone of Rio de Janeiro (distal level: adjusted OR=1·846; 95 % CI 1·002, 3·401), belonging to group I (intermediate level: adjusted OR=2·183; 95 % CI 1·066, 4·471) and for the proximal level, having a history of abortion (adjusted OR=2·840; 95 % CI 1·134, 7·115) and having anaemia during the first and second trimesters of pregnancy (adjusted OR=3·776; 95 % CI 1·579, 9·029) were determinants of gestational night blindness. CONCLUSION: Gestational night blindness should be assessed for during the prenatal care of all pregnant women, especially those living in deprived areas of the city and/or who have a history of abortion or anaemia. Nutritional monitoring is recommended during pregnancy to control gestational night blindness.

The baby-friendly hospital initiative and breastfeeding at birth in Brazil: a cross sectional study.

BACKGROUND: Breastfeeding in the first hour after birth is important for the success of breastfeeding and in reducing neonatal mortality. Government policies are being developed in this direction, highlighting the accreditation of hospitals in the Baby-Friendly Hospital (BFH) initiative. The aim of this study was to analyze the association between delivery in a BFH (main exposure), compared to non BFH, and timely initiation of breastfeeding (outcome). METHODS: Data came from the "Birth in Brazil" survey, a nationwide hospital-based study of postpartum women and their newborns, coordinated by the Oswaldo Cruz Foundation. A sample of 22,035 mothers/babies was analyzed through a hierarchical theoretical model on three levels, and all analyzes considered the complex sample design. Odds ratios were obtained by logistic regression, with a 99 % CI. RESULTS: Among all births, 40 % occurred in hospitals accredited or in accreditation process for the BFHI and 52 % of women underwent caesarean section. In the final model, at the distal level, mothers less than 35 years old, and those who lived in the North Region, had a higher chance of timely initiation of breastfeeding. At the intermediate level, prenatal care in the public sector and advice on breastfeeding during pregnancy were directly associated with the outcome. At the proximal level, being born in a Baby-Friendly Hospital and vaginal delivery increased the chance of timely initiation of breastfeeding, while prematurity and low birth weight reduced the chance of the outcome. CONCLUSIONS: The chance of being breastfed in the first hour after birth in Baby-Friendly hospitals was twice as high as at non-accredited hospitals, which shows the importance of this initiative for timely initiation of breastfeeding.

Factors associated with maternal near miss in childbirth and the postpartum period: findings from the birth in Brazil National Survey, 2011-2012.

BACKGROUND: Maternal near-miss (MNM) audits are considered a useful approach to improving maternal healthcare. The aim of this study was to evaluate the factors associated with maternal near-miss cases in childbirth and the postpartum period in Brazil. METHODS: The study is based on data from a nationwide hospital-based survey of 23,894 women conducted in 2011-2012. The data are from interviews with mothers during the postpartum period and from hospital medical files. Univariate and multivariable logistic regressions were performed to analyze factors associated with MNM, including estimation of crude and adjusted odds ratios and their respective 95 % confidence intervals (95 % CI). RESULTS: The estimated incidence of MNM was 10.2/1,000 live births (95 % CI: 7.5-13.7). In the adjusted analyses, MNM was associated with the absence of antenatal care (OR: 4.65; 95 % CI: 1.51-14.31), search for two or more services before admission to delivery care (OR: 4.49; 95 % CI: 2.12-9.52), obstetric complications (OR: 9.29; 95 % CI: 6.69-12.90), and type of birth: elective C-section (OR: 2.54; 95 % CI: 1.67-3.88) and forceps (OR: 9.37; 95 % CI: 4.01-21.91). Social and demographic maternal characteristics were not associated with MNM, although women who self-reported as white and women with higher schooling had better access to antenatal and maternity care services. CONCLUSION: The high proportion of elective C-sections performed among women in better social and economic situations in Brazil is likely attenuating the benefits that could be realized from improved prenatal care and greater access to maternity services. Strategies for reducing the rate of MNM in Brazil should focus on: 1) increasing access to prenatal care and delivery care, particularly among women who are at greater social and economic risk and 2) reducing the rate of elective cesarean section, particularly among women who receive services at private maternity facilities, where C-section rates reach 90 % of births.

Factors associated with unintended pregnancy in Brazil: cross-sectional results from the Birth in Brazil National Survey, 2011/2012.

BACKGROUND: Unintended pregnancy, a pregnancy that have been either unwanted or mistimed, is a serious public health issue in Brazil. It is reported for more than half of women who gave birth in the country, but the characteristics of women who conceive unintentionally are rarely documented. The aim of this study is to analyse the prevalence and the association between unintended pregnancy and a set of sociodemographic characteristics, individual-level variables and history of obstetric outcomes. METHODS: Birth in Brazil is a cross-sectional study with countrywide representation that interviewed 23,894 women after birth. The information about intendedness of pregnancy was obtained after birth at the hospital and classified into three categories: intended, mistimed or unwanted. Multinomial regression analysis was used to estimate the associations between intendedness of a pregnancy, and sociodemographic and obstetric variables, calculating odds ratios and 95 % confidence intervals. All significant variables in the bivariate analysis were included in the multinomial multivariate model and the final model retaining variables that remained significant at the 5 % level. RESULTS: Unintended pregnancy was reported by 55.4 % of postpartum women. The following variables maintained positive and significant statistical associations with mistimed pregnancy: maternal age < 20 years (OR = 1.89, 95 % CI: 1.68-2.14); brown (OR = 1.15, 95 % CI: 1.04-1.27) or yellow skin color (OR = 1.56, 95 % CI: 1.05-2.32); having no partner (OR = 2.32, 95 % CI: 1.99-2.71); having no paid job (OR = 1.15, 95 % CI: 1.04-1.27); alcohol abuse with risk of alcoholism (OR = 1.25, 95 % CI: 1.04-1.50) and having had three or more births (OR = 2.01, 95 % CI: 1.63-2.47). The same factors were associated with unwanted pregnancy, though the strength of the associations was generally stronger. Women with three or more births were 14 times more likely to have an unwanted pregnancy, and complication in the previous pregnancies and preterm birth were 40 % and 19 % higher, respectively. Previous neonatal death was a protective factor for both mistimed (OR = 0.61, 95 % CI: 0.44-0.85) and unwanted pregnancy (OR = 0.44, 95 % CI: 0.34-0.57). CONCLUSIONS: This study confirms findings from previous research about the influence of socioeconomic and individual risk factors on unintended pregnancy. It takes a new approach to the problem by showing the importance of previous neonatal death, preterm birth and complication during pregnancy as risk factors for unintended pregnancy.

Adequacy of public maternal care services in Brazil.

BACKGROUND: In Brazil, hospital childbirth care is available to all, but differences in access and quality of care result in inequalities of maternal health. The objective of this study is to assess the infrastructure and staffing of publicly financed labor and birth care in Brazil and its adequacy according to clinical and obstetric conditions potentially associated with obstetric emergencies. METHODS: Nationwide cross-sectional hospital-based study "Birth in Brazil: national survey into labor and birth" conducted in 2011-2012. Data from 209 hospitals classified as public (public funding and management) or mixed (public or private funding and private management) that generate estimates for 1148 Brazilian hospitals. Interview with hospital managers provided data for the structure adequacy assessment covering four domains: human resources, medications, equipment for women emergency care and support services. We conducted analysis of the structure adequacy rate according to type of hospital (public or mixed), availability of ICU and the woman obstetric risk using the X 2 test to detect differences in categorical variables with the level of statistical significance set at p <0.05. RESULTS: Global rate of adequacy of 34.8 %: 42.2 % in public hospitals and 29.0 % in mixed hospitals (p < 0.001). Public and mixed hospitals with ICU had higher scores of adequacy than hospitals without ICU (73.3 % × 24.4 % public hospitals; 40.3 % × 10.6 % mixed hospitals). At a national level, 32.8 % of women with obstetric risk were cared for in hospitals without ICU and 29.5 % of women without risk were cared for in hospitals with ICU. Inequalities were observed with the North, Northeast and non-capital regions having the lower rates of hospitals with ICU. CONCLUSIONS: The majority of maternity wards across the country have a low rate of adequacy that can affect the quality of labor and birth care. This holds true for women at high obstetric risk, who suffer the possibility of having their care compromised by failures of hospital infrastructure, and for women at low obstetric risk, who may not receive the appropriate care to support the natural evolution of their labor when in a technological hospital environment.

Factors associated with the use of supplemental oxygen or positive pressure ventilation in the delivery room, in infants born with a gestational age ≥ 34 weeks.

BACKGROUND: Approximately 5-10 % of newborns require some form of resuscitationupon delivery; several factors, such as maternal abnormal conditions, gestational age and type of delivery could be responsible for this trend. This study aimed to describe the factors associated with the need for positive pressure ventilation (PPV) via a mask or endotracheal tube and the use of supplemental O2 in newborns with a gestational age greater than 34 weeks in Brazil. METHODS: We performed a cross-sectional study and obtained data from the Birth in Brazil Survey. The inclusion criterion was a gestational age ≥34 weeks. Exclusion criteria were newborns with congenital malformations, and cases with undetermined gestational age or type of delivery (vaginal, pre labor cesarean section and cesarean section during labor). The primary outcomes were need of PPV via a mask or endotracheal tube and the use of supplemental oxygen without PPV. Confounding variables, including maternal age, source of birth payment, years of maternal schooling, previous birth, newborn presentation, multiple pregnancy, and maternal obstetric risk, were analyzed. RESULTS: We included 22,720 newborns. Of these, 2974 (13.1 %) required supplementary oxygen. PPV with a bag and mask was used for 727 (3.2 %) newborns and tracheal intubation for 192 (0.8 %) newborns. Chest compression was necessary for 136 (0.6 %) newborns and drugs administered in 114 (0.5 %). 51.3 % of newborns were delivered by cesarean section, with the majority of cesarean sections (88.7 %) being performed prior to labor. Gestational age (late preterm infants: (Relative Risk-(RR) 2.46; 95 % (Confidence interval-CI 1.79-3.39), maternal obstetric risk (RR 1.59; 95 % CI1.30-1.94), and maternal age of 12-19 years old (RR 1.36; 95 % CI1.06-1.74) contributed to rates of PPV in the logistic regression analysis. Newborns aged between 37-38 weeks of gestaional age weren´t less likely to require PPV compared with those aged 39-41 weeks of gestational age. CONCLUSIONS: Late preterm infants, previous maternal obstetric risks and maternal age contributed to the higher needs of PPV and use of O2 in the delivery room. These variables need to be considered in planning care in the delivery room.

Labor and birth care by nurse with midwifery skills in Brazil.

BACKGROUND: The participation of nurses and midwives in vaginal birth care is limited in Brazil, and there are no national data regarding their involvement. The goal was to describe the participation of nurses and nurse-midwives in childbirth care in Brazil in the years 2011 and 2012, and to analyze the association between hospitals with nurses and nurse-midwives in labor and birth care and the use of good practices, and their influence in the reduction of unnecessary interventions, including cesarean sections. METHODS: Birth in Brazil is a national, population-based study consisting of 23,894 postpartum women, carried out in the period between February 2011 and October 2012, in 266 healthcare settings. The study included all vaginal births involving physicians or nurses/nurse-midwives. A logistic regression model was used to examine the association between the implementation of good practices and suitable interventions during labor and birth, and whether care was a physician or a nurse/nurse-midwife led care. We developed another model to assess the association between the use of obstetric interventions during labor and birth to the personnel responsible for the care of the patient, comparing hospitals with decisions revolving exclusively around a physician to those that also included nurses/nurse-midwives as responsible for vaginal births. RESULTS: 16.2 % of vaginal births were assisted by a nurse/nurse-midwife. Good practices were significantly more frequent in those births assisted by nurses/nurse-midwives (ad lib. diet, mobility during labor, non-pharmacological means of pain relief, and use of a partograph), while some interventions were less frequently used (anesthesia, lithotomy position, uterine fundal pressure and episiotomy). In maternity wards that included a nurse/nurse-midwife in labour and birth care, the incidence of cesarean section was lower. CONCLUSIONS: The results of this study illustrate the potential benefit of collaborative work between physicians and nurses/nurse-midwives in labor and birth care. The adoption of good practices in managing labor and birth could be the first step toward more effective obstetric and midwifery care in Brazil. It may be easier to introduce new approaches rather than to eliminate old ones, which may explain why the reduction of unnecessary interventions during labor and birth was less pronounced than the adoption of new practices.

Prevalence and risk factors related to preterm birth in Brazil.

BACKGROUND: The rate of preterm birth has been increasing worldwide, including in Brazil. This constitutes a significant public health challenge because of the higher levels of morbidity and mortality and long-term health effects associated with preterm birth. This study describes and quantifies factors affecting spontaneous and provider-initiated preterm birth in Brazil. METHODS: Data are from the 2011-2012 "Birth in Brazil" study, which used a national population-based sample of 23,940 women. We analyzed the variables following a three-level hierarchical methodology. For each level, we performed non-conditional multiple logistic regression for both spontaneous and provider-initiated preterm birth. RESULTS: The rate of preterm birth was 11.5 %, (95 % confidence 10.3 % to 12.9 %) 60.7 % spontaneous - with spontaneous onset of labor or premature preterm rupture of membranes - and 39.3 % provider-initiated, with more than 90 % of the last group being pre-labor cesarean deliveries. Socio-demographic factors associated with spontaneous preterm birth were adolescent pregnancy, low total years of schooling, and inadequate prenatal care. Other risk factors were previous preterm birth (OR 3.74; 95 % CI 2.92-4.79), multiple pregnancy (OR 16.42; 95 % CI 10.56-25.53), abruptio placentae (OR 2.38; 95 % CI 1.27-4.47) and infections (OR 4.89; 95 % CI 1.72-13.88). In contrast, provider-initiated preterm birth was associated with private childbirth healthcare (OR 1.47; 95 % CI 1.09-1.97), advanced-age pregnancy (OR 1.27; 95 % CI 1.01-1.59), two or more prior cesarean deliveries (OR 1.64; 95 % CI 1.19-2.26), multiple pregnancy (OR 20.29; 95 % CI 12.58-32.72) and any maternal or fetal pathology (OR 6.84; 95 % CI 5.56-8.42). CONCLUSION: The high proportion of provider-initiated preterm birth and its association with prior cesarean deliveries and all of the studied maternal/fetal pathologies suggest that a reduction of this type of prematurity may be possible. The association of spontaneous preterm birth with socially-disadvantaged groups reaffirms that the reduction of social and health inequalities should continue to be a national priority.

Prenatal testing and prevalence of HIV infection during pregnancy: data from the "Birth in Brazil" study, a national hospital-based study.

BACKGROUND: The rate of vertical HIV transmission has decreased in Brazil, but regional inequalities suggest problems in implementing control measures during pregnancy and delivery. The aims of this study were to ascertain the coverage of HIV testing during prenatal care and estimate the prevalence of HIV infection during pregnancy in Brazil. METHODS: This was a national hospital-based study of 23,894 women that was conducted in 2011-2012. The data came from interviews with mothers during postpartum hospitalization, from hospital medical files and from prenatal cards. All the pregnant women with reactive serological results for HIV infection marked on their cards or with diagnoses of HIV infection during the hospital stay for delivery were considered cases of HIV infection. Univariate and multivariable logistic regression were performed to investigate factors associated with the prevalence of HIV infection and with performing at least one HIV test during pregnancy. RESULTS: Among participating women, the coverage of testing for HIV infection was 81.7% among those who presented with prenatal card and the prevalence of HIV infection among pregnant women was 0.4% (95% CI: 0.32-0.51%). In the adjusted analysis, there was higher coverage of testing among women living in the South and Southeast regions; of women aged 35 years and over; with greater schooling levels; who self-reported as white; with prenatal care provided in private services; with an early start to prenatal care; and with an adequate number of consultations, defined as a minimum of six for a term pregnancy. In the adjusted analyses there was a greater odds ratio of HIV infection among women living in the South region, aged 35 years and over, with schooling of less than 8 years, who self-reported race as black, without a partner, with syphilis coinfection and who were attended by public services. CONCLUSIONS: The prevalence of HIV infection among pregnant women in Brazil remains below 1% and the coverage of testing for HIV infection is over 80%. However, the regional and social inequalities in access to healthcare services and the missed opportunities for diagnoses of HIV infection indicate the importance of strengthening HIV infection control programs during pregnancy.

[Adequacy of prenatal care according to maternal characteristics in Brazil]. / Adequação da assistência pré-natal segundo as características maternas no Brasil.

OBJECTIVE: To verify the degree of adequacy of prenatal care in Brazil and to determine whether it is associated with sociodemographic characteristics of women. METHODS: This nationwide hospital-based study was performed with 23 894 women in 2011 and 2012. Data were obtained from interviews with puerperal women and from the prenatal card recording prenatal care appointments. Adequate prenatal care was defined as that started no later than the 12th gestational week, with performance of at least six consultations (with number of consultations adjusted for gestational age at delivery), record in the prenatal card of at least one result for each of the recommended routine prenatal tests, and guidance regarding the maternity hospital for delivery. Multivariate logistic regression was performed to verify the association between maternal characteristics and the adequacy of prenatal care. RESULTS: Early onset of prenatal care was observed in 53.9% of participants, adequate number of consultations in 73.2%, record of at least one of each recommended test in 62.9%, guidance regarding maternity hospital in 58.7%, and overall adequate prenatal care in 21.6%. Less adequate prenatal care was observed in women who were younger, black, multiparous, who did not have a partner, without paid employment, having fewer years of formal schooling, belonging to lower socioeconomic classes, and living in the North and Northeast of Brazil. After adjustment of maternal characteristics, no differences were observed between public or private health care services regarding adequacy of prenatal care. CONCLUSIONS: Even though the coverage of prenatal care is virtually universal in Brazil, regional and social differences in the access and adequacy of care still persist. The implementation of strategies to facilitate early access to prenatal care is essential.

Using Respondent-Driven Sampling (RDS) to Identify the Healthcare Needs among Women of Reproductive Age Who Migrated from Venezuela to Brazil, 2018-2021.

In 2021, an RDS survey was conducted among Venezuelan migrant women of reproductive age who migrated to two Brazilian cities (Manaus and Boa Vista) from 2018 to 2021. To start the RDS recruitment, we chose seeds non-randomly in both cities. The study variables were age, educational level, self-rated health, pregnancy, migratory status and use of health services. We estimated the prevalence, confidence intervals and homophily effects by variable category. We used a multivariate logistic regression model to identify the main factors associated with healthcare use. A total of 761 women were recruited in Manaus and 1268 in Boa Vista. Manaus showed more irregular migrants than Boa Vista. The main reasons for using health services were as follows: illness, disease prevention and prenatal care. The logistic regression model showed the use of health services was associated with educational level and healthcare needs but not with migratory status. The social inclusion of Venezuelan migrants is extremely relevant, although many challenges must be overcome. The strategy of the Brazilian Federal Government for providing humanitarian assistance to Venezuelan migrants should be expanded to include and facilitate their integration into labor markets, access to healthcare and education, benefiting both migrants and the Brazilian people by reducing social inequality.

[Factors associated with breastfeeding at birth in maternity hospitals linked to the Rede Cegonha, Brazil, 2016-2017]. / Fatores associados ao aleitamento materno ao nascer em maternidades vinculadas à Rede Cegonha, Brasil, 2016-2017.

Breastfeeding (BF) is a human right, and it must start from birth. The adequacy of Rede Cegonha (RC) strategies can contribute to the promotion of BF. The objective was to identify factors associated with BF in the first and 24 hours of live births at full-term maternity hospitals linked to CR. Cross-sectional study with data from the second evaluation cycle 2016-2017 of the RC that covered all of Brazil. Odds ratios were obtained through binary logistic regression according to a hierarchical model, with 95% confidence intervals and p-value < 0.01. The prevalence of BF in the first hour was 31% and in the 24 hours 96.6%. The chances of BF in the first hour increased: presence of a companion during hospitalization, skin-to-skin contact, vaginal delivery, delivery assistance by a nurse and accreditation of the unit in the Baby-Friendly Hospital Initiative. Similar results at 24 hours, and association with maternal age below 20 years. BF in the first hour was less satisfactory than in the 24 hours, probably due to the high prevalence of cesarean sections, a factor associated with a lower chance of early BF. Continuous training of professionals about BF and the presence of an obstetric nurse during childbirth are recommended to expand BF in the first hour.

O aleitamento materno (AM) é um direito humano e deve ser iniciado desde o nascimento. A adequação das estratégias da Rede Cegonha (RC) pode contribuir na promoção do AM. O objetivo foi identificar os fatores associados ao AM na primeira e nas 24 horas de nascidos vivos a termo em maternidades vinculadas à RC. Estudo transversal com dados do segundo ciclo avaliativo 2016-2017 da RC, que abrangeu todo o Brasil. Foram obtidas razões de chance por meio de regressão logística binária segundo modelo hierarquizado, com intervalos de confiança a 95% e p-valor < 0,01. A prevalência de AM na primeira hora foi de 31%, e nas 24 horas, de 96,6%. Aumentaram as chances de AM na primeira hora: presença de acompanhante na internação, contato pele a pele, parto vaginal, assistência ao parto por enfermeira e acreditação da unidade na Iniciativa Hospital Amigo da Criança. Resultados semelhantes nas 24 horas, e associação com idade materna inferior a 20 anos. O AM na primeira hora foi menos satisfatório do que nas 24h, provavelmente pela elevada prevalência de cesariana, fator associado à menor chance de AM precoce. A capacitação dos profissionais sobre AM de forma contínua e a presença de enfermeiro obstetra no parto são recomendadas para ampliar o AM na primeira hora.

Maternal mortality: protocol of a study integrated to the Birth in Brazil II survey. / Mortalidade materna: protocolo de um estudo integrado à pesquisa Nascer no Brasil II.

The Maternal Mortality Study conducts a hospital investigation of maternal deaths that occurred in 2020/2021 in the maternity hospitals sampled by the Birth in Brazil II survey, with the following objectives: estimate the maternal mortality underreporting; calculate a correction factor and the corrected (MMR); validate the causes of maternal mortality reported in the death certificate (DC); and analyze the factors associated with maternal mortality. The Birth in Brazil II includes approximately 24,250 puerperal women distributed in 465 public, private, and mixed hospitals with ≥ 100 live births/year in the five macroregions of Brazil. The Maternal Mortality Study data will be completed using the same Birth in Brazil II questionnaire, from the consultation of hospital records. Trained obstetricians will fill out a new DC (redone DC) from independent analysis of this questionnaire, comparing it to official data. The database of the investigated deaths will be related to the deaths listed in the Mortality Information System of the Brazilian Ministry of Health, allowing the estimation of underreporting and calculation of the corrected MMR. To calculate the reliability of the causes of death, the kappa test and prevalence-adjusted kappa with 95% confidence interval will be used. A case-control study to estimate the risk factors for maternal mortality will be developed with the investigated deaths (cases) and the controls obtained in the Birth in Brazil II survey, using conditional multiple logistic regression models. We expect this research to contribute to the correction of the underreporting of maternal mortality and to a better understanding of the determinants of the persistence of a high MMR in Brazil.

O Estudo da Mortalidade Materna conduz uma investigação hospitalar dos óbitos maternos ocorridos em 2020/2021 nas maternidades amostradas na pesquisa Nascer no Brasil II, com os seguintes objetivos: estimar o sub-registro da mortalidade materna e calcular um fator de correção e a razão de mortalidade materna (RMM) corrigida; validar as causas de mortalidade materna informadas na declaração de óbito (DO); e analisar os fatores associados à mortalidade materna. O Nascer no Brasil II inclui aproximadamente 24.255 puérperas distribuídas em 465 hospitais públicos, privados e mistos com ≥ 100 partos de nascidos vivos/ano nas cinco macrorregiões do país. Os dados do Estudo da Mortalidade Materna serão preenchidos utilizando o mesmo questionário do Nascer no Brasil II, a partir da consulta aos prontuários hospitalares. Obstetras treinados preencherão uma nova DO (DO refeita) a partir de análise independente desse questionário, comparando aos dados oficiais. A base de dados dos óbitos investigados será relacionada com os óbitos constantes no Sistema de Informações sobre Mortalidade do Ministério da Saúde, permitindo a estimativa do sub-registro e cálculo da RMM corrigida. Para o cálculo da confiabilidade das causas de morte, serão utilizados os testes kappa e kappa ajustado à prevalência com intervalo de 95% de confiança. Um estudo de caso-controle para estimar os fatores de risco para mortalidade materna será desenvolvido com os óbitos investigados (casos) e os controles obtidos na pesquisa Nascer no Brasil II, utilizando-se modelos de regressão logística múltipla condicional. Espera-se contribuir para a correção do sub-registro da mortalidade materna e para a melhor compreensão dos fatores determinantes da persistência de RMM elevada no Brasil.

El Estudio de Mortalidad Materna evalúa las muertes maternas ocurridas en 2020-2021 en las muestras de maternidades del encuesta Nacer en Brasil II con los objetivos de estimar el subregistro de mortalidad materna y calcular el factor de corrección y la tasa de mortalidad materna corregida (TMM); validar las causas de mortalidad materna reportadas en el certificado de defunción (CD); y analizar los factores asociados a la mortalidad materna. La Nacer en Brasil II incluye aproximadamente 24.250 mujeres puerperales, distribuidas en 465 hospitales públicos, privados y mixtos con ≥ 100 nacidos vivos/año en las cinco macrorregiones de Brasil. Los datos de Estudio de Mortalidad Materna se completarán con la información del cuestionario Nacer en Brasil II a partir de una búsqueda de los registros médicos hospitalarios. Los obstetras capacitados completarán un nuevo CD (CD rehecho) desde un análisis independiente de este cuestionario, comparándolo con los datos oficiales. La base de datos de muertes investigadas se relacionará con las muertes que constan en el Sistema de Informaciones sobre la Mortalidad del Ministerio de Salud para permitir la estimación del subregistro y el cálculo de la TMM corregida. Para calcular la exactitud de las causas de muerte, se utilizarán las pruebas kappa y kappa ajustada a la prevalencia con un intervalo de 95% de confianza. Un estudio de casos y controles se aplicará para estimar los factores de riesgo de las mortalidad materna con las muertes investigadas (casos) y los controles obtenidos en el estudio Nacer en Brasil II utilizando modelos de regresión logística múltiple condicional. Se espera que este estudio pueda contribuir a la corrección del subregistro de la mortalidad materna y a una mejor comprensión de los determinantes de la persistencia de alta TMM en Brasil.
