Implementation mapping applied in OASI2

Implementation mapping steps	Application 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
