[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.

Hidden cost of hospital-based delivery and associated factors among postpartum women attending public hospitals in Gamo zone, southern Ethiopia.

BACKGROUND: Since 2005, the healthcare system in Ethiopia has implemented policies to promote the provision of free maternal healthcare services. The primary goal of these policies is to enhance the accessibility of maternity care for women from various socioeconomic backgrounds. Additionally, the aim is to increase the utilization of maternity services, such as institutional deliveries, by removing financial obstacles that pregnant women may face. Even though maternity services are free of charge. The hidden cost has unquestionably been a key obstacle in seeking and utilizing health care services. Significant payments due to delivery services could create a heavy economic burden on households. OBJECTIVES: To determine the hidden cost of hospital-based delivery and associated factors among postpartum women attending public hospitals in Gamo zone, southern Ethiopia 2023. METHODS: A facility-based cross-sectional study was conducted on 411 postpartum women in Gamo Zone Public Health Hospitals from December 1, 2022, to January 30, 2023. The systematic sampling technique was applied to reach study units. Data was collected using the Kobo Toolbox Data Collection Tool and exported to SPSS statistical software version 27 for analysis. Simple linear regression and multiple linear regression were done to see the association of variables. The significance level was declared at a P-value < 0.05 in the final model. RESULT: The median hidden cost of hospital-based delivery was 1142 Ethiopian birr (ETB), with a range (Q) of 2262 (504-2766) ETB. Monthly income of the family (ß = 0.019), obstetrics complications (ß = 0.033), distance from the health facility (ß = 0.003), and mode of delivery (ß = 0.072), were positively associated with the hidden cost of hospital-based delivery. While, rural residence (ß = -0.041) was negatively associated with the outcome variable. CONCLUSION: This study showed the hidden cost of hospital based delivery was relatively high. Residence, monthly income of the family, obstetric complications, mode of delivery, and distance from the health facility were statistically significant. It is important to take these factors into account when designing health intervention programs and hospitals should prioritize the availability of essential drugs and medical supplies within their facilities to address direct medical costs in hospitals.

Variation in Breastfeeding Initiation and Duration by Mode of Childbirth: A Prospective, Population-Based Study.

Introduction: Despite known benefits of breastfeeding, including prevention against infections for infants, in the presence of numerous barriers, less than half of infants in high-income countries breastfeed for 6 months. One potential barrier to breastfeeding is birth by cesarean section (C-Section), which can invoke long-term difficulties. However, our structured literature review found that existing empirical research does not fully elucidate this relationship due to differences in operationalization of C-section and breastfeeding, omission of important confounders, and failure to exclude those who did not initiate breastfeeding (or use time-to-event analyses). In this article, we attempt to overcome these limitations. Methods: We analyzed data from 14,414 mother-infant dyads enrolled in the United Kingdom-based prospective Millennium Cohort Study, beginning in 2001. Using multivariable logistic regression, we examined the association between mode of birth (vaginal, emergency C-section, and elective C-section) and likelihood of breastfeeding initiation. We then applied adjusted Accelerated Failure Time survival models to examine the associations between mode of birth and duration of any and exclusive breastfeeding. Results: Those with planned (but not emergency) C-section were less likely to initiate breastfeeding (odds ratio: 0.84, 95% confidence interval [CI]: 0.71-0.99) relative to vaginal births. However, those with either planned or unplanned C-section discontinued both any and exclusive breastfeeding sooner than vaginal births. This effect was more pronounced for those with planned C-section (time ratio [TR]: 0.75, 95% CI: 0.64-0.89) than unplanned C-section (TR: 0.85, 95% CI: 0.74, 0.97) compared with vaginal births. Conclusions: Through application of rigorous methods, this study provides compelling evidence that breastfeeding duration may be impeded by C-section birth. The findings suggest that additional support for mothers who intend to breastfeed and have a C-section birth may be warranted.

Trends in Cesarean Delivery in Puerto Rico, 2018-2022.

Cesarean delivery is major surgery associated with higher costs and adverse outcomes, such as surgical complications, compared with vaginal delivery (1-3). The cesarean delivery rate in Puerto Rico rose from just over 30% in the early to mid-1990s to over 40% by the early 2000s (4,5). During this time, cesarean delivery rates in Puerto Rico were 40%-70% higher than rates in the U.S. mainland and up to 78% higher than rates for Hispanic women in the U.S. mainland (4,5). This report describes trends in Puerto Rico's cesarean delivery rate from 2010 to 2022 and explores changes by maternal age, gestational age, and municipality from 2018 to 2022.

Delivery mode and fetal outcome in attempted vaginal deliveries after previous cesarean section: a nationwide register-based cohort study in Finland.

PURPOSE: Even though the risks and advantages of repeat Cesarean sections (CSs) and vaginal births after cesarean section (VBACs) are well studied, there is a scarcity of information on the effects of previous CS on maternal and fetal outcomes during subsequent deliveries. The aim of this study is to evaluate delivery mode and fetal outcomes in a trial of labor after cesarean section (TOLAC). METHODS: In this nationwide retrospective cohort study, data from the National Medical Birth Register (MBR) were used to evaluate the outcomes of TOLACs. TOLACs were compared to the outcomes of the trial of labor after previous successful vaginal delivery. A multivariable logistic regression model was used to assess the primary outcomes (delivery mode, neonatal intensive care unit, and perinatal/neonatal mortality). Adjusted odds ratios (aORs) with 95% confidence intervals (CIs) were used for comparison. RESULTS: A total of 29 352 (77.0%) women attempted vaginal delivery in the TOLAC group. In the control group, 169 377 (97.2%) women attempted vaginal delivery. The adjusted odds for urgent CS (aOR 13.05, CI 12.59-13.65) and emergency CS (aOR 3.65, CI 3.26-4.08) were notably higher in the TOLAC group when compared to the control group. The odds for neonatal intensive care unit treatment (aOR 2.05, CI 1.98-2.14), perinatal mortality (aOR 2.15, CI 1.79-2.57), and neonatal mortality (aOR 1.75, CI 1.20-2.49) were higher in the TOLAC group. CONCLUSIONS: The odds for emergency CS were higher among women who underwent TOLAC. The odds for neonatal intensive care and perinatal mortality were also higher, and further research is needed to identify those expecting women who are better suited for TOLAC to minimize the risk for a neonate. The results of this study should be acknowledged by the mother and the clinician when considering the possibility of vaginal births after cesarean section.

This study uses American Hospital Association data to examine the volume and distribution of births in Catholic US hospitals and quantify county-level patterns of Catholic and non-Catholic hospital births.

Racial/ethnic disparities in costs, length of stay, and severity of severe maternal morbidity.

BACKGROUND: In contrast to other high-resource countries, the United States has experienced increases in the rates of severe maternal morbidity. In addition, the United States has pronounced racial and ethnic disparities in severe maternal morbidity, especially for non-Hispanic Black people, who have twice the rate as non-Hispanic White people. OBJECTIVE: This study aimed to examine whether the racial and ethnic disparities in severe maternal morbidity extended beyond the rates of these complications to include disparities in maternal costs and lengths of stay, which could indicate differences in the case severity. STUDY DESIGN: This study used California's linkage of birth certificates to inpatient maternal and infant discharge data for 2009 to 2011. Of the 1.5 million linked records, 250,000 were excluded because of incomplete data, for a final sample of 1,262,862. Cost-to-charge ratios were used to estimate costs from charges (including readmissions) after adjusting for inflation to December 2017. Mean diagnosis-related group-specific reimbursement was used to estimate physician payments. We used the Centers for Disease Control and Prevention definition of severe maternal morbidity, including readmissions up to 42 days after delivery. Adjusted Poisson regression models estimated the differential risk of severe maternal morbidity for each racial or ethnic group, compared with the non-Hispanic White group. Generalized linear models estimated the associations of race and ethnicity with costs and length of stay. RESULTS: Asian or Pacific Islander, Non-Hispanic Black, Hispanic, and other race or ethnicity patients all had higher rates of severe maternal morbidity than non-Hispanic White patients. The largest disparity was between non-Hispanic White and non-Hispanic Black patients, with unadjusted overall rates of severe maternal morbidity of 1.34% and 2.62%, respectively (adjusted risk ratio, 1.61; P<.001). Among patients with severe maternal morbidity, the adjusted regression estimates showed that non-Hispanic Black patients had 23% (P<.001) higher costs (marginal effect of $5023) and 24% (P<.001) longer hospital stays (marginal effect of 1.4 days) than non-Hispanic White patients. These effects changed when cases, such as cases where a blood transfusion was the only indication of severe maternal morbidity, were excluded, with 29% higher costs (P<.001) and 15% longer length of stay (P<.001). For other racial and ethnic groups, the increases in costs and length of stay were smaller than those observed for non-Hispanic Black patients, and many were not significantly different from non-Hispanic White patients. Hispanic patients had higher rates of severe maternal morbidity than non-Hispanic White patients; however, Hispanic patients had significantly lower costs and length of stay than non-Hispanic White patients. CONCLUSION: There were racial and ethnic differences in the costs and length of stay among patients with severe maternal morbidity across the groupings that we examined. The differences were especially large for non-Hispanic Black patients compared with non-Hispanic White patients. Non-Hispanic Black patients experienced twice the rate of severe maternal morbidity; in addition, the higher relative costs and longer lengths of stay for non-Hispanic Black patients with severe maternal morbidity support greater case severity in that population. These findings suggest that efforts to address racial and ethnic inequities in maternal health need to consider differences in case severity in addition to the differences in the rates of severe maternal morbidity and that these differences in case severity merit additional investigation.

Conclusão: Foi evidenciada alta taxa de cesáreas, e as principais indicações foram cesárea prévia e sofrimento fetal agudo. Os grupos 1, 2 e 5 da classificação de Robson foram os que mais contribuíram para essa taxa.

Objective: To evaluate the cesarean section rate and the cesarean indication rate based on Robson Classification during 2020 in Sã o Vicente's Municipal Maternity, a habitual-risk public hospital. Methods: This is a cross-sectional observational study. We have reviewed, corrected, analyzed retrospectively and documented Robson Classification in Sã o Vicente's Municipal Maternity. Births from January to December 2020 were analyzed, from which the main data for the research was collected and organized. Results: A sample of 1,627 births was found. The overall rate of cesarean section was 46.3%. The relative contribution of groups 1, 2 and 5 to the cesarean rate was 16.8%, 13.3% and 46.8%, respectively. While the cesarean indication relative contribution was 25.5% for previous cesarean and 21.5% for fetal distress. Conclusion: We found a high cesarean rate and the main indications were previous cesarean and fetal distress. Robson classification groups 1, 2 and 5 contributed the most to this rate.

Association Between Giving Birth During the Early Coronavirus Disease 2019 (COVID-19) Pandemic and Serious Maternal Morbidity.

OBJECTIVE: To evaluate whether delivering during the early the coronavirus disease 2019 (COVID-19) pandemic was associated with increased risk of maternal death or serious morbidity from common obstetric complications compared with a historical control period. METHODS: This was a multicenter retrospective cohort study with manual medical-record abstraction performed by centrally trained and certified research personnel at 17 U.S. hospitals. Individuals who gave birth on randomly selected dates in 2019 (before the pandemic) and 2020 (during the pandemic) were compared. Hospital, health care system, and community risk-mitigation strategies for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in response to the early COVID-19 pandemic are described. The primary outcome was a composite of maternal death or serious morbidity from common obstetric complications, including hypertensive disorders of pregnancy (eclampsia, end organ dysfunction, or need for acute antihypertensive therapy), postpartum hemorrhage (operative intervention or receipt of 4 or more units blood products), and infections other than SARS-CoV-2 (sepsis, pelvic abscess, prolonged intravenous antibiotics, bacteremia, deep surgical site infection). The major secondary outcome was cesarean birth. RESULTS: Overall, 12,133 patients giving birth during and 9,709 before the pandemic were included. Hospital, health care system, and community SARS-CoV-2 mitigation strategies were employed at all sites for a portion of 2020, with a peak in modifications from March to June 2020. Of patients delivering during the pandemic, 3% had a positive SARS-CoV-2 test result during pregnancy through 42 days postpartum. Giving birth during the pandemic was not associated with a change in the frequency of the primary composite outcome (9.3% vs 8.9%, adjusted relative risk [aRR] 1.02, 95% CI 0.93-1.11) or cesarean birth (32.4% vs 31.3%, aRR 1.02, 95% CI 0.97-1.07). No maternal deaths were observed. CONCLUSION: Despite substantial hospital, health care, and community modifications, giving birth during the early COVID-19 pandemic was not associated with higher rates of serious maternal morbidity from common obstetric complications. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT04519502.

Breech delivery in low-income settings: A systematic review of perinatal and maternal outcomes in vaginal versus cesarean breech deliveries.

Most studies comparing vaginal breech delivery (VBD) with cesarean breech delivery (CBD) have been conducted in high-income settings. It is uncertain whether these results are applicable in a low-income setting. To assess the neonatal and maternal mortality and morbidity for singleton VBD compared to CBD in low- and lower-middle-income settings,the PubMed database was searched from January 1, 2000, to January 23, 2020 (updated April 21, 2021). Randomized controlled trials (RCTs) and non-RCTs comparing singleton VBD with singleton CBD in low- and lower-middle-income settings reporting infant mortality were selected. Two authors independently assessed papers for eligibility and risk of bias. The primary outcome was relative risk of perinatal mortality. Meta-analysis was conducted on applicable outcomes. Eight studies (one RCT, seven observational) (12 510 deliveries) were included. VBD increased perinatal mortality (relative risk [RR] 2.67, 95% confidence interval [CI] 1.82-3.91; one RCT, five observational studies, 3289 women) and risk of 5-minute Apgar score below 7 (RR 3.91, 95% CI 1.90-8.04; three observational studies, 430 women) compared to CBD. There was a higher risk of hospitalization and postpartum bleeding in CBD. Most of the studies were deemed to have moderate or serious risk of bias. CBD decreases risk of perinatal mortality but increases risk of bleeding and hospitalization.

Mode of birth in monochorionic versus dichorionic twin pregnancies: a retrospective study from a large tertiary centre in Germany.

BACKGROUND: Optimal mode of birth for twins, in particular monochorionic twins, has been the subject of much debate. This retrospective study compared maternal and newborn outcomes after vaginal birth in monochorionic and dichorionic twins, utilizing a large institutional database. METHODS: Retrospective analysis focusing on 98 monochorionic-diamniotic (MC-DA) and 540 dichorionic-diamniotic (DC-DA) twin births extracted from the perinatal database of a large German hospital. Pregnancies ≥36 weeks of gestation with two viable foetuses born between 2004 and 2014 divided into planned vaginal and planned caesarean delivery were included. Descriptive analysis was performed for maternal characteristics. Odds ratios (OR) with 95% confidences intervals (CI) tested the predictive effect of vaginal birth on neonatal and maternal outcomes. RESULTS: 51.0% MC-DA and 46.7% DC-DA twin pregnancies were planned vaginal births and 44.0% MC-DA mothers and 43.7% DC-DA mothers actually gave birth vaginally. The overall rate of caesarean section (CS) during the years under observation was 79.6% for MC-DA and 77.0% for DC-DA pregnancies. There were no significant differences in neonatal outcome between the subsamples, although acidosis was observed more often in the second DC-DA twin and Apgar scores < 7 were observed more often in MC-DA twins. CONCLUSION: Vaginal birth may be recommended as an option to women with monochorionic twins as no significant differences in outcomes were found between MC-DA and DC-DA twins. However, over half of planned vaginal twin births resulted in CS.

Use of Labor Neuraxial Analgesia for Vaginal Delivery and Severe Maternal Morbidity.

Importance: Addressing severe maternal morbidity (SMM) is a public health priority in the US. Use of labor neuraxial analgesia for vaginal delivery is suggested to reduce the risk of postpartum hemorrhage (PPH), the leading cause of preventable severe maternal morbidity. Objective: To assess the association between the use of labor neuraxial analgesia for vaginal delivery and SMM. Design, Setting, and Participants: In this population-based cross-sectional study, women aged 15 to 49 years undergoing their first vaginal delivery were included. Data were taken from hospital discharge records from New York between January 2010 and December 2017. Data were analyzed from November 2020 to November 2021. Exposures: Neuraxial analgesia (ie, epidural or combined spinal-epidural) vs no neuraxial analgesia. Main Outcomes and Measures: The primary outcome was SMM, as defined by the US Centers for Disease Control and Prevention, and the secondary outcome was PPH. Adjusted odds ratios (aORs) and 95% CIs of SMM associated with neuraxial analgesia were estimated using the inverse propensity score-weighting method and stratified according to race and ethnicity (non-Hispanic White vs racial and ethnic minority women, including non-Hispanic Asian or Pacific Islander, non-Hispanic Black, Hispanic, and other race and ethnicity) and to the comorbidity index for obstetric patients (low-risk vs high-risk women). The proportion of the association of neuraxial analgesia with the risk of SMM mediated through PPH was estimated using mediation analysis. Results: Of 575 524 included women, the mean (SD) age was 28 (6) years, and 46 065 (8.0%) were non-Hispanic Asian or Pacific Islander, 88 577 (15.4%) were non-Hispanic Black, 104 866 (18.2%) were Hispanic, 258 276 (44.9%) were non-Hispanic White, and 74 534 (13.0%) were other race and ethnicity. A total of 400 346 women (69.6%) were in the low-risk group and 175 178 (30.4%) in the high-risk group, and 272 921 women (47.4%) received neuraxial analgesia. SMM occurred in 7712 women (1.3%), of which 2748 (35.6%) had PPH. Before weighting, the incidence of SMM was 1.3% (3486 of 272 291) with neuraxial analgesia compared with 1.4% (4226 of 302 603) without neuraxial analgesia (risk difference, -0.12 per 100; 95% CI, -0.17 to -0.07). After weighting, the aOR of SMM associated with neuraxial analgesia was 0.86 (95% CI, 0.82-0.90). Decreased risk of SMM associated with neuraxial analgesia was similar between non-Hispanic White women and racial and ethnic minority women and between low-risk and high-risk women. More than one-fifth (21%; 95% CI, 14-28) of the observed association of neuraxial analgesia with the risk of SMM was mediated through the decreased risk of PPH. Conclusions and Relevance: Findings from this study suggest that use of neuraxial analgesia for vaginal delivery is associated with a 14% decrease in the risk of SMM. Increasing access to and utilization of labor neuraxial analgesia may contribute to improving maternal health outcomes.

Survival Without Severe Neonatal Morbidity in Very Preterm Twins According to Planned Mode of Delivery.

OBJECTIVE: To assess survival to discharge without severe neonatal morbidity by planned mode of delivery for twins born before 32 weeks of gestation. METHODS: The JUMODA (JUmeaux MODe d'Accouchement) study was a French national prospective, population-based, cohort study of twin deliveries conducted from February 2014 to March 2015. This planned secondary analysis included diamniotic twin pregnancies from 26 0/7 through 31 6/7 weeks of gestation. Exclusion criteria included contraindications to vaginal delivery and situations for which planned cesarean delivery is favored, and neonatal prognosis depends largely on the underlying pathology rather than the planned mode of delivery. The primary outcome was survival to discharge without severe neonatal morbidity (bronchopulmonary dysplasia, grade 3 or grade 4 intraventricular hemorrhage, periventricular leukomalacia, stage 2 or stage 3 necrotizing enterocolitis). The association between planned mode of delivery and primary outcome was assessed by multivariate Poisson regression model. A propensity-score approach with inverse probability of treatment weighting also was performed to control for indication bias. Subgroup analyses according to birth order and sensitivity analyses limited to spontaneous preterm births only were performed. RESULTS: Among 424 very preterm twin pregnancies, 192 (45.3%) had a planned cesarean delivery and 232 (54.7%) had a planned vaginal delivery. Survival to discharge without severe morbidity did not differ in the two groups: 308 of 384 (80.2%) after planned cesarean and 375 of 464 (80.8%) after planned vaginal delivery (crude relative risk 0.99; 95% CI 0.91-1.15; adjusted relative risk 1.02; 95% CI 0.93-1.11). After applying inverse probability of treatment weighting, planned cesarean delivery still was not associated with higher survival to discharge without severe neonatal morbidity than planned vaginal birth (relative risk 1.11; 95% CI 0.84-1.46). Subgroup and sensitivity analyses showed similar results. CONCLUSION: Planned cesarean delivery for very preterm twins is not associated with higher survival to discharge without severe neonatal morbidity than planned vaginal delivery. These results suggest that very preterm delivery should not be considered a per se indication for planned cesarean in twin pregnancies.

Risk of infection in neonates born in accidental out-of-hospital deliveries.

Accidental out-of-hospital deliveries (OHDs) are known to have a higher incidence of maternal and neonatal complications. However, neonatal infection related to OHDs has not been studied. The aim of this study was to determine the infection risk of OHDs. This retrospective cohort study enrolled neonates admitted at a children's hospital in an urban setting from January 2004 to December 2017. Accidental OHDs were compared with in-hospital births, and neonatal infection was assessed. This study also investigated both maternal and neonatal risk factors associated with OHDs. A cohort of 158 OHD neonates was enrolled, of whom 29 (23.2%) were preterm. Prematurity and low birth weight were significantly associated with OHD. Eight neonates in the OHD cohort had a documented infection within the first 72 hours of life, which was 11-fold higher than infections documented for the in-hospital births. Multivariate analysis identified low birth weight as the only factor independently associated with increased risk of infection in OHD neonates. Several specific characteristics of mothers with OHDs were identified. Forty-nine (31%) OHD mothers lacked antenatal care, and 10 (6.3%) were unaware of their pregnancies. The OHD group comprised of more teenage mothers compared to the in-hospital deliveries category. Neonatal infection was more prevalent among OHDs than for in-hospital deliveries, and the infection rate was associated with low birth weight. Hospitalization for further care and observation is suggested for the OHD neonates. Social support should be provided for populations with an increased risk of OHD, such as teenage mothers.

Effectiveness of emergency obstetric care training at the regional level in Ukraine: a non-randomized controlled trial.

BACKGROUND: Emergency obstetric care training, using Advances in Labour and Risk Management (ALARM) International Program (AIP) was implemented in Ukraine, a country with universal access to skilled perinatal and obstetric care but restricted resources. A total of 577 providers (65.5% of total) from 28 maternal clinics attended a 5-day training session focused on the five main causes of maternal mortality, with hands-on skill workshops, pre- and post- tests, and an objective structured clinical examination. The effects of this emergency obstetric care training on maternal outcomes is the subject of this paper. METHODS: A non-randomized controlled trial was conducted. The pilot areas where the training was implemented consisted of 64 maternity clinics of which 28 were considered as cases and 36 non-participating clinics were the referents. Data on maternal outcomes were collected for a 2-year span (2004-2005) prior to the trainings, which took place 2006-2007 and again after implementation of the trainings, from 2008 to 2009. Information was collected from 189,852 deliveries. Outcomes for the study were incidences of operative delivery and postpartum hemorrhage. Non-parametric statistics, meta-analyses, and difference in difference (DID) estimation were used to assess the effect of the AIP on maternal indices. RESULTS: DID analysis showed that after the training, compared to the referents, the cases had significant reduction of blood transfusions (OR: 0.56; 95%CI: 0.48-0.65), plasma transfusions (OR: 0.70; 95%CI: 0.63-0.78), and uterus explorations (OR: 0.64; 95%CI: 0.59-0.69). We observed a non-significant reduction of postpartum hemorrhage ≥1000 ml (OR: 0.92; 95%CI: 0.81-1.04; P = 0.103). Utilization of vacuum extraction for vaginal delivery increased (OR: 2.86; 95%CI: 1.80-4.57), as well as forceps assisted delivery (OR: 1.80; 95%CI: 1.00-3.25) and cesarean section (OR: 1.11; 95%CI: 1.06-1.17). There was no change in the occurrence of postpartum hysterectomy and maternal mortality. CONCLUSIONS: After one week of Emergency Obstetrics Care training of the obstetric staff in a setting with universal access to perinatal and obstetric care but restricted resources, an association with the reduction of postpartum hemorrhage related interventions was observed. The effects on the use of vacuum extraction and cesarean section were minimal. TRIAL REGISTRATION: Retrospectively registered 071212007807 from 07/12/2012.

Trends in Venous Thromboembolism and Associated Risk Factors During Delivery Hospitalizations From 2000 to 2018.

OBJECTIVE: To characterize trends in and risk factors for venous thromboembolism (VTE) during delivery hospitalizations in the United States. METHODS: The 2000-2018 National Inpatient Sample was used for this repeated cross-sectional analysis. Venous thromboembolism (including deep vein thrombosis [DVT] and pulmonary embolism) during delivery hospitalizations for women aged 15 to 54 years was determined by year. Temporal trends in VTE were characterized using joinpoint regression with estimates presented as the average annual percent change. Temporal trends in common VTE risk factors were also analyzed. The proportion of vaginal and cesarean deliveries by year that had VTE risk factors was determined, and average annual percent changes with 95% CIs were calculated. The relationship between risk factors and the likelihood of VTE events was determined with adjusted and unadjusted logistic regression models. RESULTS: Of 73,109,789 delivery hospitalizations, 48,546 VTE events occurred (6.6/10,000 deliveries), including 37,312 DVT diagnoses and 12,487 pulmonary embolism diagnoses. Rates increased significantly for vaginal (average annual percent change 2.5%, 95% CI 1.5-3.5%) but not for cesarean delivery hospitalizations (average annual percent change 0.3%, 95% CI -1.0 to 1.6%) over the study period. Pulmonary embolism increased for both vaginal delivery (average annual percent change 8.7%, 95% CI 6.0-11.5%) and cesarean delivery (average annual percent change 4.9%, 95% CI 3.6-6.2%). The proportion of cesarean deliveries with at least one VTE risk factor increased from 27.2% in 2000 to 43.6% in 2018 (average annual percent change 2.6%, 95% CI 2.2-3.1%) and for vaginal deliveries, from 17.7% to 31.4% (average annual percent change 3.4%, 95% CI 2.3-4.4%). The 5.9% of deliveries with at least two VTE risk factor diagnoses accounted for 25.4% of VTE diagnoses. Factors with the highest VTE risk included transfusion (adjusted odds ratio [aOR] 4.1, 95% CI 3.7-4.5), infection (aOR 5.8, 95% CI 5.3-6.3), history of VTE (aOR 7.2, 95% CI 6.2-8.4), and thrombophilias (aOR 9.6, 95% CI 8.5-11.0). CONCLUSION: Both risk factors for VTE and rate of pulmonary embolism increased over the study period. Deep vein thrombosis increased during vaginal delivery hospitalizations but not during cesarean delivery hospitalizations.

Preeclampsia at delivery is associated with lower serum vitamin D and higher antiangiogenic factors: a case control study.

BACKGROUND: Preeclampsia is characterized by decreased trophoblastic angiogenesis leading to abnormal invasion of spiral arteries, shallow implantation and resulting in compromised placentation with poor uteroplacental perfusion. Vitamin D plays an important role in pregnancy influencing implantation, angiogenesis and placental development. The objective of this study was to determine whether there is an association between serum vitamin D levels, and anti-angiogenic factors at the time of delivery and the occurrence of preeclampsia. METHODS: This nested case control study analyzed frozen serum samples at the time of delivery and related clinical data from women with singleton liveborn pregnancies who had participated in studies of the NICHD Stillbirth Collaborative Research Network. Women with a recorded finding of preeclampsia and who had received magnesium sulfate treatment prior to delivery were considered index cases (N = 56). Women without a finding of preeclampsia were controls (N = 341). RESULTS: Women with preeclampsia had 14.5% lower serum vitamin D levels than women in the control group (16.5 ng/ml vs. 19 ng/ml, p = 0.014) with 64.5% higher sFlt-1 levels (11,600 pg/ml vs. 7050 pg/ml, p < 0.001) and greater than 2 times higher endoglin levels (18.6 ng/ml vs. 8.7 ng/ml, < 0.001). After controlling for gestational age at delivery and maternal BMI, vitamin D levels were 0.88 times lower (P = 0.051), while endoglin levels were 2.5 times higher and sFlt-1 levels were 2.1 times higher than in control pregnancies (P < 0.001). CONCLUSIONS: Women with preeclampsia at time of delivery have higher maternal antiangiogenetic factors and may have lower maternal serum vitamin D levels. These findings may lead to a better understanding of the underlying etiology of preeclampsia as well as possible modifiable treatment options which could include assuring adequate levels of maternal serum vitamin D prior to pregnancy.

Stillbirth and neonatal mortality in a subsequent pregnancy following stillbirth: a population-based cohort study.

BACKGROUND: A history of stillbirth is a risk factor for recurrent fetal death in a subsequent pregnancy. Reported risks of recurrent fetal death are often not stratified by gestational age. In subsequent pregnancies increased rates of medical interventions are reported without evidence of perinatal benefit. The aim of this study was to estimate gestational-age specific risks of recurrent stillbirth and to evaluate the effect of obstetrical management on perinatal outcome after previous stillbirth. METHODS: A retrospective cohort study in the Netherlands was designed that included 252.827 women with two consecutive singleton pregnancies (1st and 2nd delivery) between 1999 and 2007. Data was obtained from the national Perinatal Registry and analyzed for pregnancy outcomes. Fetal deaths associated with a congenital anomaly were excluded. The primary outcome was the occurrence of stillbirth in the second pregnancy stratified by gestational age. Secondary outcome was the influence of obstetrical management on perinatal outcome in a subsequent pregnancy. RESULTS: Of 252.827 first pregnancies, 2.058 pregnancies ended in a stillbirth (8.1 per 1000). After adjusting for confounding factors, women with a prior stillbirth have a two-fold higher risk of recurrence (aOR 1.96, 95% CI 1.07-3.60) compared to women with a live birth in their first pregnancy. The highest risk of recurrence occurred in the group of women with a stillbirth in early gestation between 22 and 28 weeks of gestation (a OR 2.25, 95% CI 0.62-8.15), while after 32 weeks the risk decreased. The risk of neonatal death after 34 weeks of gestation is higher in women with a history of stillbirth (aOR 6.48, 95% CI 2.61-16.1) and the risk of neonatal death increases with expectant obstetric management (aOR 10.0, 95% CI 2.43-41.1). CONCLUSIONS: A history of stillbirth remains an important risk for recurrent stillbirth especially in early gestation (22-28 weeks). Women with a previous stillbirth should be counselled for elective induction in the subsequent pregnancy at 37-38 weeks of gestation to decrease the risk of perinatal death.

Effect of four or more antenatal care visits on facility delivery and early postnatal care services utilization in Uganda: a propensity score matched analysis.

INTRODUCTION: Maternal mortality remains a global public health issue, more predominantly in developing countries, and is associated with poor maternal health services utilization. Antenatal care (ANC) visits are positively associated with facility delivery and postnatal care (PNC) utilization. However, ANC in itself may not lead to such association but due to differences that exist among users (women). The purpose of this study, therefore, is to examine the effect of four or more ANC visits on facility delivery and early PNC and also the effect of facility-based delivery on early PNC using Propensity Score Matched Analysis (PSMA). METHODS: The present study utilized the 2016 Uganda Demographic and Health Survey (UDHS) dataset. Women aged 15 - 49 years who had given birth three years preceding the survey were considered for this study. Propensity score-matched analysis was used to analyze the effect of four or more ANC visits on facility delivery and early PNC and also the effect of facility-based delivery on early PNC. RESULTS: The results revealed a significant and positive effect of four or more ANC visits on facility delivery [ATT (Average Treatment Effect of the Treated) = 0.118, 95% CI: 0.063 - 0.173] and early PNC [ATT = 0.099, 95% CI: 0.076 - 0.121]. It also found a positive and significant effect of facility-based delivery on early PNC [ATT = 0.518, 95% CI: 0.489 - 0.547]. CONCLUSION: Policies geared towards the provision of four or more ANC visits are an effective intervention towards improved facility-based delivery and early PNC utilisation in Uganda.
