Is proactive telephone-based breastfeeding peer support a cost-effective intervention? A within-trial cost-effectiveness analysis of the 'Ringing Up about Breastfeeding earlY' (RUBY) randomised controlled trial

OBJECTIVE

The 'Ringing Up about Breastfeeding earlY' (RUBY) randomised controlled trial showed increased breastfeeding at 6 months in participants who received the proactive telephone-based peer support breastfeeding intervention compared with participants allocated to receive standard care and supports. The present study aimed to evaluate if the intervention was cost-effective.

DESIGN

A within-trial cost-effectiveness analysis.

SETTING

Three metropolitan maternity services in Melbourne, Victoria, Australia.

PARTICIPANTS

First time mothers intending to breastfeed their infant (1152) and peer volunteers (246).

INTERVENTION

The intervention comprised proactive telephone-based support from a peer volunteer from early postpartum up to 6 months. Participants were allocated to usual care (n=578) or the intervention (n=574).

MAIN OUTCOME MEASURES

Costs during a 6-month follow-up period including individual healthcare, breastfeeding support and intervention costs in all participants, and an incremental cost-effectiveness ratio.

RESULTS

Costs per mother supported were valued at $263.75 (or $90.33 excluding costs of donated volunteer time). There was no difference between the two arms in costs for infant and mothers in healthcare and breastfeeding support costs. These figures result in an incremental cost-effectiveness ratio of $4146 ($1393 if volunteer time excluded) per additional mother breast feeding at 6 months.

CONCLUSION

Considering the significant improvement in breastfeeding outcomes, this intervention is potentially cost-effective. These findings, along with the high value placed on the intervention by women and peer volunteers provides robust evidence to upscale the implementation of this intervention.

Sources of information during pregnancy and the early parenting period: Exploring the views of women and their partners

OBJECTIVE

There are a wide variety of information sources available during pregnancy and the early parenting period, but limited understanding of their usefulness, particularly for partners. We explored the views of both women and their partners regarding sources of information, their frequency of use, and their preferred formats.

DESIGN AND SETTING

Data were collected as part of a large cluster randomised controlled trial at a tertiary maternity hospital in 2015-2016, in Melbourne, Australia. The overall evaluation was of a parenting kit ('Growing Together'), an evidence-based information source for prospective and new parents covering the period from conception until one year postpartum. This paper uses data collected from women when their baby was two months of age, and women's partners when the baby was six months of age, via postal or online survey.

PARTICIPANTS

Women were eligible if they booked for pregnancy care at The Royal Women's Hospital during the recruitment period, were having their first baby, able to read and speak English without an interpreter, and <30 weeks pregnant at their first hospital appointment (n = 1034). All eligible women were included unless they opted out.

MEASUREMENTS AND FINDINGS

In total 92 women were excluded. Of the women sent the two-month survey, 42% (392/941) responded. Partner surveys were returned by 252/791 partners (32%). Respondents received information from a range of sources, most frequently face to face from health professionals through childbirth education or midwife discussion/education, followed by friends and family members. Information received from a health professional was also reported as being the most useful. For both women and their partners, the most important factor related to information was that it was from a trusted and reliable source.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

Women and their partners highlighted the importance of quality and access to evidence based resources and information. The internet is frequently favoured by women and their partners due to its convenience, accessibility, and timely access to information. Overall, women and their partners reported information directly from a health care professional to be the most useful and health services should ensure that women and their partners have adequate access to their health care professional.

Infant feeding practices in the first 24-48 h of life in healthy term infants

AIM

To examine in-hospital infant feeding practices, focusing on initiation and prevalence of breastmilk expression and to describe the proportion of women having a breast pump immediately after birth.

METHODS

Postpartum women were recruited from three hospitals in Melbourne, Australia, between 2009 and 2011.

INCLUSION CRITERIA

having had a healthy singleton term infant, intending to breastfeed and fluency in English. Data were collected using a structured questionnaire.

RESULTS

Just over 1000 women were recruited at 24-48 h postpartum; 50% were primiparous. Forty-seven per cent of infants had been fully breastfeeding at the breast from birth, and another 47% had received at least some expressed breastmilk. Forty per cent of first-time mothers reported having had a problem breastfeeding, and 46% already had a breast pump prior to the birth of their infant.

CONCLUSIONS

Early breastfeeding problems were common, and less than half the infants had fed only at the breast in the first days of life. Given the normalization of breastmilk expression, more evidence is needed regarding the impact of expressing on duration of breastmilk feeding and maternal health outcomes.

Effects of continuity of care by a primary midwife (caseload midwifery) on caesarean section rates in women of low obstetric risk: the COSMOS randomised controlled trial

OBJECTIVE

To determine whether primary midwife care (caseload midwifery) decreases the caesarean section rate compared with standard maternity care.

DESIGN

Randomised controlled trial.

SETTING

Tertiary-care women's hospital in Melbourne, Australia.

POPULATION

A total of 2314 low-risk pregnant women.

METHODS

Women randomised to caseload received antenatal, intrapartum and postpartum care from a primary midwife with some care by 'back-up' midwives. Women randomised to standard care received either midwifery or obstetric-trainee care with varying levels of continuity, or community-based general practitioner care.

MAIN OUTCOME MEASURES

PRIMARY OUTCOME

caesarean birth. Secondary outcomes included instrumental vaginal births, analgesia, perineal trauma, induction of labour, infant admission to special/neonatal intensive care, gestational age, Apgar scores and birthweight.

RESULTS

In total 2314 women were randomised-1156 to caseload and 1158 to standard care. Women allocated to caseload were less likely to have a caesarean section (19.4% versus 24.9%; risk ratio [RR] 0.78; 95% CI 0.67-0.91; P = 0.001); more likely to have a spontaneous vaginal birth (63.0% versus 55.7%; RR 1.13; 95% CI 1.06-1.21; P < 0.001); less likely to have epidural analgesia (30.5% versus 34.6%; RR 0.88; 95% CI 0.79-0.996; P = 0.04) and less likely to have an episiotomy (23.1% versus 29.4%; RR 0.79; 95% CI 0.67-0.92; P = 0.003). Infants of women allocated to caseload were less likely to be admitted to special or neonatal intensive care (4.0% versus 6.4%; RR 0.63; 95% CI 0.44-0.90; P = 0.01). No infant outcomes favoured standard care.

CONCLUSION

In settings with a relatively high baseline caesarean section rate, caseload midwifery for women at low obstetric risk in early pregnancy shows promise for reducing caesarean births.
