Abstract

The impact of elective induction of labour at term on the increasing caesarean section (CS) rate is unclear. A Cochrane Systematic Review that concluded that elective induction was associated with a reduction in CS was based on trials that mostly reflect outdated obstetric care, or were flawed. The findings of other studies vary widely in the magnitude and direction of the relationship between elective induction and CS. This inconsistency may be due to the heterogeneity in the methods used to induce or augment labour, such that the relationship with CS is not constant across methods. Using validated, routinely-collected data on all births in Victoria in 2000-2005, all singleton, cephalic, first births following uncomplicated pregnancies at 37-40 completed weeks' gestation ('standard primiparae') were identified (n = 42,950). As well as comparing induced with non-induced labour, method of birth was compared between those women experiencing spontaneous labour without augmentation, and women undergoing each method of augmentation or induction using adjusted multinomial logistic regression. Proportions, chi-square tests, adjusted Relative Risk Ratios (aRRR) and 95 % confidence intervals are presented. Ten percent of "standard primiparae" had labour induced for no apparent medical indication. Women whose labour was induced were significantly more likely than those who laboured spontaneously to have a CS (26.5 and 12.5 % respectively (OR 2.54, 95 % CI 2.4, 2.7, p < 0.001). After adjustment for maternal age, epidural analgesia, birthweight, gestation, and public/private admission status, each method of induction or augmentation remained associated with a significant increase in the risk of CS (adjusted ORs range 1.48 to 4.13, p-values all <0.0001). Perinatal death did not differ by onset of labour. Induction of labour in medically uncomplicated nulliparous women at term carries a more than doubling of risk of emergency CS, compared with spontaneous labour, with no impact on perinatal mortality. All methods of induction and augmentation of labour were associated with an increase in the rate of CS. Women included in this study had no apparent medical indication for induction of labour or any complication of pregnancy, so the increase in CS was not due to identifiable underlying risk factors. These results suggest that, in the absence of direction from well-designed, contemporary RCTs, minimising unindicated inductions before 41 weeks' gestation has the potential to reduce the rate of CS.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 29. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 16 July 2022.
All research outputs
#1,266,970
of 24,284,650 outputs
Outputs from BMC Pregnancy and Childbirth
#273
of 4,522 outputs
Outputs of similar age
#21,897
of 303,467 outputs
Outputs of similar age from BMC Pregnancy and Childbirth
#12
of 71 outputs
Altmetric has tracked 24,284,650 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 94th percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 4,522 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 9.0. This one has done particularly well, scoring higher than 93% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 303,467 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 92% of its contemporaries.
We're also able to compare this research output to 71 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 84% of its contemporaries.
