Ten years of a publicly funded homebirth service in Victoria: Maternal and neonatal outcomes

Intrapartum time intervals and transfer of nulliparae from community births to maternity care units in Germany

BACKGROUND

Over one-third of nulliparae planning births either at home or in freestanding midwife-led birthing centers (community births) in high-income countries are transferred during labor. Perinatal data are reported each year in Germany for women planning community birth. So far, data sets have not been linked to describe time-related factors associated with nulliparous transfer to hospital.

OBJECTIVES

To describe the prevalence of referral for nulliparae and assess maternal and labor characteristics associated with intrapartum transfer.

METHODS

Perinatal data from 2010 to 2015 were linked (n = 26,115). Women were reviewed with respect to international eligibility criteria for community birth; 1997 women were excluded (7.6%). Descriptive statistics were reported; unadjusted and adjusted odds ratios with 95% confidence intervals (CI) tested the predictive effect of demographic and labor factors on rates of intrapartum transfer.

RESULTS

One in three nulliparous women (30.6%) were transferred to hospital. Compared with community births, transferred women were significantly more likely to experience longer time intervals during labor: from rupture of membranes (ROM) until birth lasting 5 to 18 h (OR 6.05, CI 5.53-6.61) and 19 to 24 h (OR 10.83, CI 9.45-12.41) compared to one to 4 h; and from onset of labor until birth 11 to 24 h (OR 6.72, CI 6.24-7.23) and 25 to 29 h (OR 26.62, CI 22.77-31.11) compared to one to 10 h. When entering all factors into the model, we found the strongest predictors of transfer to be fetal distress, longer time intervals between ROM until birth and onset of labor until birth.

CONCLUSIONS

Nulliparous transfer rates were similar to rates in other high-income countries; 94% of referrals were non-urgent. Time was found to be an independent risk factor for the transfer of nulliparae planning community birth.

The financial impact of offering publicly funded homebirths: A population-based microsimulation in Queensland, Australia

BACKGROUND

Despite strong evidence of benefits and increasing consumer demand for homebirth, Australia has failed to effectively upscale it. To promote the adoption and expansion of homebirth in the public health care system, policymakers require quantifiable results to evaluate its economic value. To date, there has been limited evaluation of the financial impact of birth settings for women at low risk of pregnancy complications.

OBJECTIVE

This study aimed to examine the difference in inpatient costs around birth between offering homebirth in the public maternity system versus not offering public homebirth to selected women who meet low-risk pregnancy criteria.

METHODS

We used a whole-of-population linked administrative dataset containing all women who gave birth in Queensland (one Australian State) between 01/07/2012 and 30/06/2018 where publicly funded homebirth is not currently offered. We created a static microsimulation model to compare the inpatient cost difference for mother and baby around birth based on the women who gave birth between 01/07/2017 and 30/06/2018 (n = 36,314). The model comprised of a base model - representing standard public hospital care, and a counterfactual model - representing a hypothetical scenario where 5 % of women who gave birth in public hospitals planned to give birth at home prior to the onset of labour (n = 1816). Costs were reported in 2021/22 AUD.

RESULTS

In our hypothetical scenario, after considering the effect of assumptive place and mode of birth for these planned homebirths, the estimated State-level inpatient cost saving around birth (summed for mother and babies) per pregnancy were: AU$303.13 (to Queensland public hospitals) and AU$186.94 (to Queensland public hospital funders). This calculates to a total cost saving per annum of AU$11 million (to Queensland public hospitals) and AU$6.8 million (to Queensland public hospital funders).

CONCLUSION

A considerable amount of inpatient health care costs around birth could be saved if 5 % of women booked at their local public hospitals, planned to give birth at home through a public-funded homebirth program. This finding supports the establishment and expansion of the homebirth option in the public health care system.

Relationships are the key to a successful publicly funded homebirth program, a qualitative study

BACKGROUND

In Australia, publicly-funded homebirth is a relatively new option for women and their families. Two years after the inception of two publicly funded homebirth services in Victoria in 2009, a study found that midwives' experiences were more positive than doctors. There is no recent evidence on the perspectives of midwives and doctors of publicly-funded homebirth programs.

AIM

To explore the experiences of midwives and doctors participating in or supporting one publicly-funded homebirth program in Australia.

METHODS

An interpretive descriptive approach was used following individual in-depth interviews via 'Zoom'. Participants included midwives and doctors who provide or support the homebirth service at a large metropolitan health service in Melbourne's western suburbs. Data were thematically analysed.

FINDINGS

Interviews were conducted with 16 homebirth midwives, six hospital-based midwives, and nine doctors. One central theme and three sub-themes demonstrate that effective relationships are critical to a successful publicly-funded homebirth program. Collaboration, teamwork, and mutual respect across professions were reported to be integral to success. The midwife-woman relationship was highly valued and especially important to provide continuity during transfers to the hospital where this occurred.

DISCUSSION

Effective relationships underpin collaborative practice and are critical for safe healthcare. Shared common learning opportunities such as simulation training sessions and multi-professional forums to discuss cases were perceived to assist the development of these relationships.

CONCLUSION

Effective relationships within and between midwives and doctors are key to collaborative practice, which underpins a successful publicly-funded homebirth service. Health services can support this by maintaining a respectful and supportive culture amongst staff.
