Methods of induction of labor and women's experience: a population-based cohort study with mediation analyses.

BACKGROUND: Negative childbirth experience may affect mother wellbeing and health. However, it is rarely evaluated in studies comparing methods of induction of labor (IoL). AIM: To compare women's experience of IoL according to the method, considering the mediating role of interventions and complications of delivery. METHODS: We used data from the MEDIP prospective population-based cohort, including all women with IoL during one month in seven French perinatal networks. The experience of IoL, assessed at 2 months postpartum, was first compared between cervical ripening and oxytocin, and secondarily between different cervical ripening methods. Mediation analyses were used to measure the direct and indirect effects of cervical ripening on maternal experience, through delivery with interventions or complications. FINDINGS: The response rate was 47.8% (n = 1453/3042). Compared with oxytocin (n = 541), cervical ripening (n = 910) was associated less often with feelings that labor went 'as expected' (adjusted risk ratio for the direct effect 0.78, 95%CI [0.70-0.88]), length of labor was 'acceptable' (0.76[0.71-0.82]), 'vaginal discomfort' was absent (0.77[0.69-0.85]) and with lower global satisfaction (0.90[0.84-0.96]). Interventions and complications mediated between 6 and 35% of the total effect of cervical ripening on maternal experience. Compared to the dinoprostone insert, maternal experience was not significantly different with the other prostaglandins. The balloon catheter was associated with less pain. DISCUSSION: Cervical ripening was associated with a less positive experience of childbirth, whatever the method, only partly explained by interventions and complications of delivery. CONCLUSION: Counselling and support of women requiring cervical ripening might be enhanced to improve the experience of IoL.

Patient attitudes towards outpatient cervical ripening prior to induction of labour at an Australian tertiary hospital.

A prospective patient questionnaire was conducted to assess attitudes and opinions towards outpatient cervical ripening in women attending an Australian tertiary hospital's labour and birth suite for a booked induction of labour. Questionnaires were distributed over a three-month period and information collected included demographic data, pregnancy and obstetric history, attitudes towards cervical ripening and willingness to undergo cervical ripening in the outpatient setting. Responses to 57 completed questionnaires were analysed. Forty-one patients (72%) underwent cervical ripening with Foley Catheter Balloon (FCB) only, eight (14%) with FCB and vaginal prostaglandins (VP), two (3.5%) with VP only and six patients (10.5%) did not require cervical ripening. One-third (33%) of patients stated, both before the commencement of cervical ripening and after delivery, that they would feel happy to undergo outpatient cervical ripening. Patient acceptance of outpatient cervical ripening has potential economic and psychosocial benefits for the healthcare system and patient respectively.
