Exploring the role of Patient and Public Involvement in Implementation Research using the Study of Implementation of Midwifery Continuity of Carer (SIMCA).

The SIMCA study has been used to illustrate the significant contributions that PPI can make to an implementation study and to the study team culture, in particular the value of having different perspectives within the team to ensure the study does not become too far removed from lived experience. Dilemmas related to the blurring between PPI and data collection and the need for more theoretical understanding of PPI in implementation research to make the findings more generalisable.
