The decreasing trend in early-term repeat cesarean deliveries in the United States: 2005 through 2014

Trends in cesarean birth rates in Iceland over a 19-year period

BACKGROUND

Cesarean birth (CB) rates have increased in high-resource countries during the past two decades, yet it is not known whether CB rates have changed according to maternal age and/or gestational age.

METHODS

All singleton live births in Iceland between 1997 and 2015 were identified from the Icelandic Medical Birth Registry (80 130). Rates of cesarean births (intrapartum and prelabor) were calculated overall and separately for maternal age groups and gestational age groups and by parity. Logit binomial regression was used to calculate odds ratios (ORs) and confidence intervals (CIs) for annual change in cesarean birth rates adjusted for maternal characteristics and clinical indication groups.

RESULTS

The overall CB rate was 15.7% in 1997 and 15.8% in 2015; the CB rate did not change significantly during the study period. The overall CB rate for early-term deliveries (37-38 weeks) decreased for multiparas (annual aOR = 0.99 [95% CI = 0.98-0.99]), and the preterm (<37 weeks) prelabor cesarean rate increased significantly (1.11 [1.09-1.14]) for both primiparas and multiparas. For multiparas only, the intrapartum CB rate decreased (0.97 [0.97-0.98]), whereas the prelabor CB rate increased, predominantly for women aged over 35 years (1.03 [1.02-1.04]). Adjustment for clinical indication groups did not change these results.

CONCLUSIONS

Findings indicate a rise in prelabor cesarean for preterm births and women aged over 35 years (multiparas only). As adjustment for clinical indications did not affect these results, changes in obstetric practice are more likely to have affected these rate changes rather than changes in clinical indications.

The impact of cesarean section on neonatal outcomes at a university-based tertiary hospital in Jordan

Background

Over the past two decades, there has been a steady rise in the rate of Cesarean section delivery globally. As a result, short-term and long-term maternal and neonatal complications are rising. The objective of this study is to determine the rate and indications for Cesarean section at King Abdullah University Hospital (KAUH) in Jordan and to assess the resulting neonatal outcomes.

Methods

A retrospective chart review was conducted for all women and neonates delivered by Cesarean section during the period January 2016 to July 2017 at KAUH tertiary academic center. Collected data include demographic characteristics, indication for delivery, and neonatal outcomes such as NICU admission, respiratory complications, sepsis, mortality, and length of hospitalization.

Results

Two thousand five hundred ninety-five Cesarean section deliveries were performed over 18 months representing a rate of 50.5% of all deliveries. Sixty percent were scheduled procedures. Seventy-two percent were performed at full term gestation. The most common indication was previously scarred uterus (42.8%) followed by fetal distress (15.5%). The rate of admission to the neonatal ICU was 30% (800/2595). After multilogistic conditional regression analysis, the factors associated with increased risk of neonatal ICU admission were found to include grandmultiparity (Adjusted OR 1.46), gestational diabetes (Adjusted OR 1.92), maternal employment (Adjusted OR 1.84), prolonged rupture of membranes (Adjusted OR 5), fetal distress (Adjusted OR 1.84), prematurity (Adjusted OR 43.78), low birth weight (Adjusted OR 42), high order multiple gestation (Adjusted OR 9.58) and low 5-min APGAR score (Adjusted OR 10). Among the babies electively delivered at early term (37–38.6 weeks), 16% were admitted to the NICU for a median length of stay of 4 days (IQR 2, 8). The most common diagnoses for admitted term neonates were transient tachypnea of newborns and respiratory distress syndrome.

Conclusions

CS deliveries account for more than half the number of deliveries at our institution and almost one third of the delivered babies are admitted to the NICU. Together with the resulting maternal and neonatal consequences, this carries a major burden on the newborns, health care facilities, and involved families. Local strategies and policies should be established and implemented to improve the outcome of births.
