Impact of planned versus emergency cesarean delivery on neonatal outcomes in pregnancies complicated by abnormal placentation: A systematic review and meta-analysis.

ABSTRACT:

Background

Although planned cesarean delivery (PCD) is the mainstay of management for abnormal placentation, some patients still require emergency cesarean delivery (ECD). We aimed to systematically analyze the impact of various modes of delivery on neonatal outcomes.

Methods

This study was complied with the PRISMA guidelines and was registered in the PROSPERO (code: CRD42022379487). A systematic search was conducted on Ovid MEDLINE and Embase, Web of Science, PubMed, and the Cochrane databases. Data extracted included gestational age at delivery, birth weight, the Apgar scores at 1 and 5 minutes, numbers of newborns with low Apgar score (<7) at 5 minutes, the rates of neonatal intensive care unit admission, and the rates of neonatal mortality.

Results

Fifteen cohort studies met the inclusion criteria, comprising a total of 2565 women (2567 neonates) who underwent PCD (n = 1483) or ECD (n = 1082) for prenatally diagnosed placenta accreta spectrum (PAS) and/or placenta previa (PP). Compared with the ECD group, neonates in the PCD group had significantly higher gestational ages (standardized mean difference [SMD]: 2.20; 95% confidence interval [CI]: 1.25-3.15; P < .001), birth weights (SMD: 1.64; 95% CI: 1.00-2.27; P < .001), and Apgar scores at 1 minute (SMD: 0.51; 95% CI: 0.29-0.73; P < .001) and 5 minutes (SMD: 0.47; 95% CI: 0.25-0.70; P < .001). Additionally, the PCD group had significantly lower rates of neonatal intensive care unit admission (odds ratio [OR]: 0.21; 95% CI: 0.14-0.29; P < .001), low Apgar score at 5 minutes (OR: 0.27; 95% CI: 0.11-0.69; P = .01), and neonatal mortality (OR: 0.13; 95% CI: 0.05-0.33; P < .001).

Conclusion

When pregnancies are complicated by abnormal placentation, PCD is linked to noticeably better neonatal outcomes than emergent delivery.

Project description:BACKGROUND:Preterm premature rupture of membranes (PPROM) is associated with high neonatal morbidity and mortality. However, the influences of cesarean section (CS) on neonatal outcomes in preterm pregnancies complicated with PPROM are not well elucidated. The aim of this study was to investigate the influence of delivery modes on neonatal outcomes among pregnant women with PPROM. METHODS:A retrospective cross-sectional study was conducted in 39 public hospitals in 14 cities in the mainland of China from January 1st, 2011 to December 31st, 2011. A total of 2756 singleton pregnancies complicated with PPROM were included. Adverse neonatal outcomes including early neonatal death, birth asphyxia, respiratory distress syndrome (RDS), pneumonia, infection, birth trauma, and 5-min/10-min Apgar scores were obtained from the hospital records. Binary variables and ordinal variables were respectively calculated by binary logistic regressions and ordinal regression. Numerical variables were compared by multiple linear regressions. RESULTS:In total, 2756 newborns were involved in the analysis. Among them, 1166 newborns (42.31%) were delivered by CS and 1590 newborns belonged to vaginal delivery (VD) group. The CS proportion of PPROM obviously increased with the increase of gestational age (??=?5.014, P?=?0.025). Compared with CS group, VD was associated with a higher risk of total newborns mortality (odds ratio [OR], 2.38; 95% confidence interval [CI], 1.102-5.118; P?=?0.027), and a lower level of pneumonia (OR, 0.32; 95% CI, 0.126-0.811; P?=?0.016). However, after multivariable adjustment and stratification for gestational age, only pneumonia was significantly related with CS in 28 to 34 weeks group (OR, 0.34; 95% CI, 0.120-0.940; P?=?0.038). There were no differences regarding to other adverse outcomes in the two groups, including neonatal mortality, birth asphyxia, Apgar scores, RDS, pneumonia, and sepsis. CONCLUSIONS:The proportion of CS of pregnant women with PPROM was very high in China. The mode of delivery does not affect neonatal outcomes of pregnancies complicated with PPROM.

Project description:ObjectiveTo assess the impact of a web-based decision aid on patient-centered decision making outcomes among women considering a trial of labor after cesarean (TOLAC) versus planned repeat cesarean delivery.MethodsThe Birth Decision Aid Study (B-READY) was a quasi-experimental pre-post study of two sequential cohorts. From June 18, 2018 to July 31, 2019, 50 women were enrolled in routine care, followed by 50 women who were enrolled in the decision aid group. Inclusion criteria were singleton pregnancies between 19/0 to 36/6 weeks, ≤2 prior cesareans, and no contraindications to TOLAC. The decision aid group viewed the online Healthwise® "Pregnancy: Birth Options After Cesarean" program. Both groups received the same birth options counseling and completed the same online assessment. Primary patient-centered outcomes were knowledge about birth options and shared decision making at online assessment, and informed, patient-centered decision making about her preferred mode of delivery at delivery admission.ResultsAmong 100 women participated in this study (50 per group), the mean gestational age at enrollment was 31 weeks, and 71% or 63/89 women who consented to delivery data abstraction had a cesarean delivery. Women in the patient decision aid group gained more knowledge (defined as score ≥ 75%) about birth options compared to those in the routine care group (72% vs. 32%; adjusted odds ratio, AOR: 6.15 [95% CI: 2.34 to 16.14]), and were more likely to make an informed, patient-centered decision (60% vs. 26%; AOR: 3.30 [95% CI: 1.20 to 9.04]. Women in both groups reported similar involvement in shared decision making, as well as satisfaction and values. More than 90% of decision aid users reported it was a useful tool and would recommend it to other TOLAC-eligible women.ConclusionsA web-based birth options patient-centered decision aid for TOLAC eligible women can be integrated into prenatal Telehealth and may improve the quality of decision making about mode of delivery.Trial registrationThe study was registered with ClinincalTrials.gov and the ID# was NCT04053413 .

Project description:ObjectiveTo evaluate whether there is a differential benefit of planned Cesarean delivery (CD) over planned vaginal delivery (VD) in women with a twin pregnancy and the first twin in cephalic presentation, depending on prespecified baseline maternal and pregnancy characteristics, and/or gestational age (GA) at delivery.MethodsThis was a secondary analysis of the Twin Birth Study, which included 2804 women with a twin pregnancy and the first twin (Twin A) in cephalic presentation between 32 + 0 and 38 + 6 weeks' gestation at 106 centers in 25 countries. Women were assigned randomly to either planned CD or planned VD. The main outcome measure was composite adverse perinatal outcome, defined as the occurrence of perinatal mortality or serious neonatal morbidity in at least one twin. The baseline maternal and pregnancy characteristics (markers) considered were maternal age, parity, history of CD, use of antenatal corticosteroids, estimated fetal weight (EFW) of Twin A, EFW of Twin B, > 25% difference in EFW between the twins, presentation of Twin B, chorionicity on ultrasound, method of conception, complications of pregnancy, ruptured membranes at randomization and GA at randomization. Separate logistic regression models were developed for each marker in order to model composite adverse perinatal outcome as a function of the specific marker, planned delivery mode and the interaction between these two terms. In addition, multivariable logistic regression analysis with backward variable elimination was performed separately in each arm of the trial. The association between planned mode of delivery and composite adverse perinatal outcome, according to GA at delivery, was assessed using logistic regression analysis.ResultsOf the 2804 women initially randomized, 1391 were included in each study arm. None of the studied baseline markers was associated with a differential benefit of planned CD over planned VD in the rate of composite adverse perinatal outcome. GA at delivery was associated differentially with composite adverse perinatal outcome in the treatment arms (P for interaction < 0.001). Among pregnancies delivered at 32 + 0 to 36 + 6 weeks, there was a trend towards a lower rate of composite adverse perinatal outcome in those in the planned-VD group compared with those in planned-CD group (29 (2.2%) vs 48 (3.6%) cases; odds ratio (OR) 0.62 (95% CI, 0.37-1.03)). In pregnancies delivered at or after 37 + 0 weeks, planned VD was associated with a significantly higher rate of composite adverse perinatal outcome, as compared with planned CD (23 (1.5%) vs 10 (0.7%) cases; OR, 2.25 (95% CI, 1.06-4.77)).ConclusionThe perinatal outcome of twin pregnancies with the first twin in cephalic presentation may differ depending on GA at delivery and planned mode of delivery. At 32-37 weeks, planned VD seems to be favorable, while, from around 37 weeks onwards, planned CD might be safer. The absolute risks of adverse perinatal outcomes at term are low and must be weighed against the increased maternal risks associated with planned CD. © 2019 The Authors.

Project description:BackgroundMaternal obesity complicates a high number of pregnancies. The degree to which neonatal outcomes are adversely affected is unclear.ObjectiveThis study aimed to evaluate neonatal outcomes of pregnancies complicated by maternal obesity.Study designThis study was a secondary analysis of a cohort of deliveries occurring on randomly selected days at 25 hospitals from 2008 to 2011. Data were collected by certified abstractors. This analysis included singleton deliveries between 24 and 42 weeks of gestation. Body mass index was calculated on the basis of maternal height and most recent weight before delivery. Normal and overweight (reference group; body mass index, 18.5-29.9 kg/m2), obese (body mass index, 30.0-39.9 kg/m2), morbidly obese (body mass index, 40.0-49.9 kg/m2), and super morbidly obese (body mass index, ≥50 kg/m2) patients were compared. Patients in the reference group were matched in a 1:1 ratio with those in all other groups with obesity using the baseline characteristics of age, race and ethnicity, previous cesarean delivery, preexisting diabetes mellitus, chronic hypertension, parity, cigarette use, and insurance status. The primary outcome was composite neonatal morbidity, including fetal or neonatal death, hypoxic-ischemic encephalopathy, respiratory distress syndrome, intraventricular hemorrhage grade 3 or 4, necrotizing enterocolitis, sepsis, birth injury, seizures, or ventilator use. We used a modified Poisson regression to examine the associations between body mass index and composite neonatal outcome. Preterm delivery at <37 weeks of gestation and the presence of maternal preeclampsia or eclampsia were included in the final model because of their known associations with neonatal outcomes.ResultsOverall, 52,162 patients and their neonates were included after propensity score matching. Of these, 21,704 (41.6%) were obese, 3787 (7.3%) were morbidly obese, and 590 (1.1%) were super morbidly obese. A total of 2103 neonates (4.0%) had the composite outcome. Neonates born to pregnant people with morbid obesity had a 33% increased risk of composite neonatal morbidity compared with those in the reference group (adjusted odds ratio, 1.33; 95% confidence interval, 1.17-1.52), but no significant association was observed for persons with obesity (adjusted odds ratio, 1.05; 95% confidence interval, 0.97-1.14) or with super morbid obesity (adjusted odds ratio, 1.18; 95% confidence interval, 0.86-1.64).ConclusionCompared with the reference group, gravidas with morbid obesity were at higher risk of composite neonatal morbidity.

Project description:IMPORTANCE:Planned cesarean delivery comprises a significant proportion of births globally, with combined rates of planned and unscheduled cesarean delivery in a number of regions approaching 50%. Observational studies have shown that offspring born by cesarean delivery are at increased risk of ill health in childhood, but these studies have been unable to adjust for some key confounding variables. Additionally, risk of death beyond the neonatal period has not yet been reported for offspring born by planned cesarean delivery. OBJECTIVE:To investigate the relationship between planned cesarean delivery and offspring health problems or death in childhood. DESIGN, SETTING, AND PARTICIPANTS:Population-based data-linkage study of 321,287 term singleton first-born offspring born in Scotland, United Kingdom, between 1993 and 2007, with follow-up until February 2015. EXPOSURES:Offspring born by planned cesarean delivery in a first pregnancy were compared with offspring born by unscheduled cesarean delivery and with offspring delivered vaginally. MAIN OUTCOMES AND MEASURES:The primary outcome was asthma requiring hospital admission; secondary outcomes were salbutamol inhaler prescription at age 5 years, obesity at age 5 years, inflammatory bowel disease, type 1 diabetes, cancer, and death. RESULTS:Compared with offspring born by unscheduled cesarean delivery (n?=?56,015 [17.4%]), those born by planned cesarean delivery (12,355 [3.8%]) were at no significantly different risk of asthma requiring hospital admission, salbutamol inhaler prescription at age 5 years, obesity at age 5 years, inflammatory bowel disease, cancer, or death but were at increased risk of type 1 diabetes (0.66% vs 0.44%; difference, 0.22% [95% CI, 0.13%-0.31%]; adjusted hazard ratio [HR], 1.35 [95% CI, 1.05-1.75]). In comparison with children born vaginally (n?=?252,917 [78.7%]), offspring born by planned cesarean delivery were at increased risk of asthma requiring hospital admission (3.73% vs 3.41%; difference, 0.32% [95% CI, 0.21%-0.42%]; adjusted HR, 1.22 [95% CI, 1.11-1.34]), salbutamol inhaler prescription at age 5 years (10.34% vs 9.62%; difference, 0.72% [95% CI, 0.36%-1.07%]; adjusted HR, 1.13 [95% CI, 1.01-1.26]), and death (0.40% vs 0.32%; difference, 0.08% [95% CI, 0.02%-1.00%]; adjusted HR, 1.41 [95% CI, 1.05-1.90]), whereas there were no significant differences in risk of obesity at age 5 years, inflammatory bowel disease, type 1 diabetes, or cancer. CONCLUSIONS AND RELEVANCE:Among offspring of women with first births in Scotland between 1993 and 2007, planned cesarean delivery compared with vaginal delivery (but not compared with unscheduled cesarean delivery) was associated with a small absolute increased risk of asthma requiring hospital admission, salbutamol inhaler prescription at age 5 years, and all-cause death by age 21 years. Further investigation is needed to understand whether the observed associations are causal.

Project description:BackgroundWomen with pregnancy complications benefit from closer monitoring postpartum and beyond. Increased postpartum emergency room (ER) use may indicate unmet need for outpatient obstetrics and primary care. The purpose of this study was to evaluate whether women with pregnancy complications (gestational diabetes [GDM], gestational hypertension, and preeclampsia) have increased ER use in the first 6 months postpartum, compared with women without these complications.MethodsWe conducted a retrospective population-based cohort study using a 2003-2010 Maryland Medicaid managed care claims data set, linked with U.S. Census data. Data included claims for outpatient and ER visits for women aged 12-45 years who were continuously enrolled in Medicaid for at least 100 days of pregnancy and 90 days postpartum. We used logistic regression to calculate the association between pregnancy complications and having ≥1 ER visit in the 6 months postpartum.ResultsWe identified 26,074 pregnancies, of which 20% were complicated by GDM, gestational hypertension, or preeclampsia. Of these complicated pregnancies, 42.1% had GDM, 35.4% had gestational hypertension, and 42.5% had preeclampsia (diagnoses were not mutually exclusive). In the 6 months postpartum, 25% of women had ≥1 ER visits. Of the complicated pregnancy group, 27.7% had ≥1 ER visit, versus 23.6% of the comparison group (p<0.0001). In adjusted analyses, women with a pregnancy complication were more likely to have ≥1 ER visit compared with women without these complications (odds ratio [OR]1.14, 95% confidence interval [CI] 1.05-1.23). The strength of association was highest in women under age 25 (OR 1.20, 95% CI 1.09-1.33). Preconception medical comorbidities (type 2 diabetes, chronic hypertension, obesity, asthma, mental health, and substance abuse diagnoses) were also strongly associated with postpartum ER use (OR 1.61, 95% CI 1.51-1.73).ConclusionsPregnancy complications increased ER utilization during the 6 months postpartum, especially among women under age 25 years. Interventions that improve discharge planning and early postpartum care may decrease ER use.
