Table 1 Implementation mapping applied in OASI2

1. Conduct a needs and assets assessment and identify adopters and implementers

• Review of implementation process and lessons learned in OASI1

• Distinguish between roles of senior staff, implementation facilitators and clinicians

2. Identify adoption and implementation outcomes, performance objectives, and determinants; create matrices of change

• Establish roles, objectives and outcomes for senior staff, implementation facilitators, clinicians, and women receiving the care bundle

3. Choose theoretical methods; select or create implementation strategies

• Selection of the PARIHS framework, implementation outcomes framework

• Theory of Change (see Additional file 1) and Logic model development (Fig. 4)

4. Produce implementation protocols and materials

• Tailoring of ERIC strategies across study arms (see Table 2)

• Co-design of the Implementation Toolkit with reference to clinicians’ and women’s experiences in OASI1, incorporating results from Shared Learning Day and PPI collaboration

5. Evaluate implementation outcomes

• Plan evaluation of clinical outcomes

• Plan evaluation of implementation outcomes
