“…41 Similar to our findings, previous research found that cesarean delivery was more common on weekdays than weekends, which might reflect prescheduling of cesarean delivery and inductions of labor. 42,43 Recent research indicated a lower rate of cesarean delivery associated with induction compared with expectant management. 43 These findings highlight the need of collaborative approaches to reduce low-risk cesarean delivery, including equitable implementation of clinical guidance to support the management and treatment of chronic and pregnancy-induced conditions, supportive delivery care for women, and health system incentives to enhance quality of care in an equitable way.…”

To assess variations in low-risk cesarean delivery rates in the United States using the Society for Maternal-Fetal Medicine (SMFM) definition of low-risk for cesarean delivery and to identify factors associated with low-risk cesarean deliveries. METHODS:From hospital discharge data in the 2018 National Inpatient Sample and State Inpatient Databases, we identified deliveries that were low-risk for cesarean delivery using the SMFM definition based on the International Classification of Diseases, Tenth Revision, Clinical Modification codes. We estimated national low-risk cesarean delivery rates overall and by patient characteristics, clinically relevant conditions not included in the SMFM definition, and hospital characteristics based on the nationally representative sample of hospital discharges in the National Inpatient Sample. Multivariate logistic regressions were estimated for the national sample to identify factors associated with low-risk cesarean delivery. We reported low-risk cesarean delivery rates for 27 states and the District of Columbia based on the annual state data that represented the universe of hospital discharges from participating states in the State Inpatient Databases.RESULTS: Of an estimated 3,634,724 deliveries in the 2018 National Inpatient Sample, 2,484,874 low-risk deliveries met inclusion criteria. The national low-risk cesarean delivery rate in 2018 was 14.6% (95% CI 14.4-14.8%). The rates varied widely by state (range 8.9-18.6%). Nationally, maternal age older than 40 years, non-Hispanic Black or Asian race, private insurance as primary payer, admission on weekday, obesity, diabetes, or hypertension, large metropolitan residence, and hospitals of the South census region were associated with lowrisk cesarean delivery.CONCLUSION: Approximately one in seven low-risk deliveries was by cesarean in 2018 in the United States using the SMFM definition and the low-risk cesarean delivery rates varied widely by state.

“…Those authors found that women had a 25-29 % lower chance of having a C-section on weekends and holidays compared to weekdays. 35 In the same line, Young et al described a phenomenon called the "weekend effect," during which the number of births and the percentage of C-sections are lower compared to weekdays. 36 In relation to the time of birth, it was observed that births increased progressively between 7:00 a.m. and 2:00 p.m. and remained high until 9:00 p.m.…”

Introduction. There is a worldwide growing trend of preterm births and C-sections. Our objective was to describe gestational age (GA), mode of delivery, day and time distribution, and the relation between the mode of delivery and the time of birth in two private facilities. Population and methods. Prospective, crosssectional, analytical study. Results. A total of 1500 live newborn infants were included between September 2017 and August 2018 (1465 pregnant women). Of these, 99.4 % had received antenatal care; 66.8 % of pregnancies ended via C-section. The reason was a previous C-section in 36.4 %, lack of progression and descent in 18.9 %, and maternal choice in 9.2 %. The average birth weight was 3232 g ± 561.1 g and the median GA was 39 weeks (range: 38-40) based on the date of the last menstrual period; 88.2 % were term births and, among preterm births, 76.1 % corresponded to late preterm babies. Early term births showed a higher rate of C-sections (p < 0.001). There were 849/1201 (74.5 %) C-sections on weekdays and 173/299 (57.9 %, p < 0.001) on weekends and holidays. A statistically significant relation was observed between the time of birth and the performance of a C-section. Conclusions. The median GA was 39 weeks. C-sections were the most common mode of delivery. Births occurred predominantly Mondays through Fridays between 8 a.m. and 9 p.m.; 82.9 % of C-sections took place on weekdays.

“…Estos autores encontraron que las madres tenían entre el 25 % y el 29 % menos de probabilidad de tener una cesárea en los días de fin de semana o feriado comparados con los días de semana. 35 En la misma línea, Young y cols. describieron un fenómeno denominado "efecto del fin de semana", momento en el que se producían menos nacimientos y menor porcentaje de cesáreas comparados con los días de semana.…”
