Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Birthing in Our Community is a complex intervention designed to improve maternal and infant health outcomes for Indigenous families in an urban setting. Launched in 2013, Birthing in Our Community was developed in partnership between the Mater Mothers Hospital, and two local Aboriginal community-controlled health organisations: the Institute for Urban Indigenous Health and the Aboriginal and Torres Strait Islander Community Health Service Brisbane Ltd.

Key components of the intervention include:
• Indigenous governance (operating through a Steering Committee) functioning in accordance with Terms of Reference and underpinned by a MOU
• A community-based Midwifery Group Practice (MGP), which provides continuity of carer to enrolled women throughout pregnancy, birth and up to six weeks postnatally. Care is provided according to hospital guidelines and protocols in the home, at community venues where regular cultural and education days are held, or in the hospital
• 24/7 access to caseload midwife who works in MGP on annualised salary with each woman allocated a primary midwife. Midwife support during birthing is likely to be by a known midwife
• Location for birth is the Birth Suite (no homebirth or Birth Centre services provided)
• Indigenous Maternal Infant Health/ Family Support Workers and Indigenous student midwives work with the caseload midwives to provide culturally tailored care
• Referral to Indigenous community support agencies as required; All women are offered a formal handover to child health services with other referrals as required (e.g. paediatric, allied health)
• Clinical / cultural supervision for staff
• Indigenous Liaison Officers are based in the hospital to strengthen culturally responsive care and support
• Access to medical staff, allied health professionals, social workers, child safety officers and other professionals as required (e.g. Diabetic educator)
• Discharge letter to referral doctor and referrals to community support agencies as required

Treatment: Other
Comparator / control treatment
Ngarrama Indigenous Maternity Service (Active Concurrent Control Group 4 - Jul 2013 to Dec 2019) at RBWH
• A hospital-based Midwifery Group Practice (MGP), which provides continuity of carer to enrolled women throughout pregnancy, birth and up to six weeks postnatally. Care is provided according to hospital guidelines and protocols, regardless of setting (women’s homes, community venues or hospital)
• 24/7 access to MGP midwives who work in a small team and are on annualised salary with each woman allocated a primary midwife. Midwife support during birthing is likely to be by a known midwife.
• Location for birth may be in the Birth Suite or the co-located Birth Centre (eligibility criteria apply);
• Access to Cultural Capability Officers of the Metro North Aboriginal and Torres Strait Islander Health Unit who provide additional cultural guidance and support.

Standard Care (Historical Control Group 2 - Jan 2009 to Jun 2013 & Active Concurrent Control Group 5 - Jul 2013 to Dec 2019, at both hospitals )
• Antenatal care may be received from community based general practitioner, hospital based midwives or doctors who rotate throughout the service on rosters. Midwife support during birthing is likely to be by a person the woman has never met. Postnatal care or phone call from a rostered community midwife might take place if the woman meets the criteria for early discharge—before 48 h for vaginal birth and 72 h for caesarean section usually for up to less than 2 weeks
• Women can call the hospital birthing suite in an emergency
• Location for birth same as other groups for the hospitals
• Some aspects of the Intervention may be present but not all and there is no overarching Indigenous governance or clinical / cultural supervision for staff


Standard Care non-Indigenous babies and their mothers (Historical Control Group 3 - Jan 2009 to Jun 2013 & Active Concurrent Control Group 6 - Jul 2013 to Dec 2019, at both hospitals
• Antenatal care may be received from community based general practitioner, hospital based midwives or doctors who rotate throughout the service on rosters. Midwife support during birthing is likely to be by a person the woman has never met. Postnatal care or phone call from a rostered community midwife might take place if the woman meets the criteria for early discharge—before 48 h for vaginal birth and 72 h for caesarean section usually for up to less than 2 weeks
• Women can call the hospital birthing suite in an emergency
• Location for birth same as other groups for the hospitals

Statistical methods / analysis
Quantitative analyses will compare the difference in clinical outcomes between Birthing in Our Community (intervention), the Ngarrama Service (concurrent control), standard care (historical and concurrent control), and also non-Indigenous women and babies (historical and concurrent control) at MMH and RBWH.

This study has been powered to detect changes in clinical outcomes. During the 3.5 year recruitment period, we will aim to access routinely collected data for approximately 420 women at MMH, and 350 from RBWH (based on an estimated 20% attrition rate). The change in outcomes has been estimated based on changes seen in the Townsville Mums and Bubs program that reported a reduction in preterm birth.

Initial bivariate analysis will investigate possible differences between the cohorts for baseline socio-demographic (socio-economic status), and clinical characteristics (e.g. age, parity, BMI, smoking, obstetric history) that could affect outcome measures. Dependent on data type, analysis will be undertaken using an independent samples t-test, Mann-Whitney U test or chi-squared test. Outcome measures will be presented using relative risks with 95% confidence intervals. Multivariate logistic, linear regression models and propensity score matching will be used to adjust for confounders. Longitudinal outcomes (e.g. breastfeeding) will be analysed with generalized estimating equations to account for the correlation between observations repeated in the same person. To understand the mechanism or process that underlies the effect of model of care on outcomes, mediation analysis will be conducted to identify if and to what extent the other variables explains the relationship. All withdrawals, losses to follow-up, and deaths will be reported. Analysis will be performed with SPSS Version 22.0/Stata 14.0 and statistical significance will be at the 0.05 level.

The cost-effectiveness analysis will be conducted to examine the direct costs, from a societal perspective, to women and their families, maternity and child health care services and other community services in relation to pregnancy and birth. We will compare the mean costs per mother/infant pair between Birthing in Our Community (Group 1) and the Ngarrama Service (Group 4) to standard care group (Group 2 and 5) up to six weeks postpartum. Costs will be calculated for both mother and baby to include: women and family’s out-of-pocket expenses related to clinic appointments, outpatients (ultrasound, pathology, etc.) and prescribed medicines, and hospitalisation costs. Data will be collected through routinely collected information as well as questions embedded in the 36 week antenatal and two month postnatal surveys. Average costs for each mother and infant for the duration of the maternity episode (i.e. from when she first confirmed her pregnancy to six weeks postnatal) will be calculated and compared to determine the cost effectiveness of a model of care.

Summary
Brief summary
With persisting maternal and infant health disparities, new models of maternity care are needed to meet the needs of Aboriginal and Torres Strait Islander people in Australia. To date, there is limited evidence of successful and sustainable programs. Birthing on Country is an emerging evidence-based and community-led model of maternity care; the principles underpin a newly established service model: Birthing in Our Community. The Indigenous Birthing in an Urban Setting study is a mixed-methods prospective birth cohort study comparing different models of care for women having Aboriginal and Torres Strait Islander babies at two major maternity hospitals in urban South East Queensland. It includes women’s surveys (booking-in to model at~20 weeks gestation, 36 weeks gestation, two and six months postnatal) and infant assessments (two and six months postnatal), clinical outcomes and cost comparison, and qualitative interviews with women and staff. This study aims to evaluate the feasibility, acceptability, sustainability, effectiveness and efficiency of a Birthing on Country model of care for Aboriginal and Torres Strait Islander families in an urban setting. If successful, findings will inform implementation of the model with similar communities.
