Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Two midwives will deliver the intervention. The first visit will involve the midwife consulting face-to-face with antenatal primary health care providers to discuss local needs, priorities and protocols; promote the use of best practice protocols and guidelines; and to discuss IT needs, inputs and outputs including key performance indicators reports and recall systems. Following this there will be a weekly scheduled telephone support service between the intervention midwives and primary care staff delivering antenatal care in the primary care services, and ongoing support for services to conduct CQI activities. The intervention midwives will help to solve problems that affect how care is delivered for mothers and babies in the Kimberley. Each service will have direct input into the role of the supporting intervention midwives in their own clinics. This will include offering help with:

1. Improving the coordination of care and information exchange between service providers, both community based services and hospitals in the region and outside the region (e.g. referrals; communication processes; logistics [PATS, transport, accommodation]);

2. Improving and promoting the use of local service protocols and guidelines to support staff with these processes

3. Improving training especially for antenatal and infant health care, nutrition, substance abuse, social and emotional well-being, and prevention and management of maternal anaemia

4. Supporting staff to sort out the complex care sometimes required for specific health problems that mothers and babies may have; and

5. Other problem solving as requested.

As this is a stepped wedge cluster randomised trial the total duration of the intervention provided to each clinic will depend on which cluster the clinic is randomised to. Cluster 1, 2, 3 and 4 will receive 23, 19, 15 and 11 months of intervention, respectively.

Eligibility
Key inclusion criteria
Target group for the intervention
The target group for the intervention includes all clinics that provide antenatal care in the Kimberley region (this includes both primary care and hospital antenatal clinics). All consenting primary care and hospital antenatal services in the region will be eligible to receive the intervention and will be allocated to a cluster group based on geographical and health service provider boundaries. All pregnant women who are patients of these services will be able to receive the benefits of the intervention.

Inclusion criteria for the intervention
All primary health care clinics that provide antenatal care in the Kimberley will be included in the study

Target group for the outcome data collection
The target group for the six month post-partum data collection are Aboriginal and Torres Strait Islander infants aged six months and their mothers.

Inclusion criteria for the outcome data collection
1. Birth mother or infant is Aboriginal and / or Torres Strait Islander
2. Birth mother aged 16 years or older, or assessed as a mature minor at the time of giving informed consent
3. Birth mother gives informed consent for her baby and herself to participate in outcome data collection.
Minimum age
No limit
Maximum age

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation involved contacting the holder of the allocation schedule who are 'off-site' or at central administration site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomisation table created by a computer software (i.e., computerised sequence generation).

Efficacy
Statistical methods / analysis
Analysis of the primary outcome (iron deficiency anaemia (IDA) in infants aged six months) will occur at the individual infant level and will use binary logistic regression incorporating generalised estimating equations (GEE) to account for loss of independence due to clustering. The primary independent variable will be whether or not the mother received her first antenatal visit at an intervention clinic. This will give rise to an odds ratio for the effect of the intervention on the probability of IDA. The analysis will adjust for individual covariates, e.g. maternal age, which may differ between groups receiving or not receiving care from the intervention clinics at a given step. Analysis will be on the basis of intention to treat, regardless of movement between clusters. Similar techniques will be used for comparison of IDA in mothers at six months post-partum. Similar techniques will be used for comparison of the other secondary outcomes. We will descriptively assess effects on neurodevelopmental subgroups (i.e. cognitive, neuromotor) but will not perform statistical tests.
