Effect of antenatal education in small classes versus standard auditorium-based lectures on use of pain relief during labour and of obstetric interventions: results from the randomised NEWBORN trial

Objective To examine the effect of an antenatal education programme in small classes versus standard auditorium-based lectures. Design Randomised trial using random-generated web-based 1:1 allocation. Setting The largest birth site in the Capital Region of Denmark, from August 2012 to May 2014. Participants 1766 pregnant women. Inclusion criteria 18years, pregnant with a single child, and able to speak and understand Danish. Women were enrolled in the trial from 10+0 to 20+0weeks of gestation. Interventions The intervention programme consisted of three times 2.5hours of antenatal education in small classes (n=6-8 women), and focused on improving information and problem-solving skills for expectant parents in order to ease birth and the transition to parenthood. The control group received standard auditorium-based lectures consisting of two times 2hours in an auditorium with participation of approximate to 250 people. Main outcome measures The primary trial outcome was use of epidural analgesia. Other types of pain relief and obstetric interventions were analysed as explorative outcomes. Results There was no statistically significant difference in use of epidural analgesia between participants in the intervention group (30.9%) versus the control group (29.1%), adjusted OR 1.10 (95% CI 0.87 to 1.34). Also, the two groups did not differ regarding other types of pain relief or obstetric interventions. Concomitant birth preparation was common in both groups and highest in the control group, but did not seem to influence our results noticeably. Conclusions Antenatal education in small groups versus standard auditorium-based lectures did not differ regarding use of epidural analgesia, other pain relief, or obstetric interventions.
