Our aim is to provide decision makers with a practical evidence base to support implementation of the MCP Vanguards. Our synthesis will develop a conceptual framework which articulates what works, why and in what circumstances, by using an innovative combination of best fit framework synthesis and realist synthesis to yield unique insights. This synthesis will inform design and implementation of future iterations of the MCP model, by:
- articulating underlying programme theories behind the MCP model;
- identifying sources of theoretical, empirical and practice evidence to test programme theories;
- appraising, extracting and analysing evidence, reconciling confirmatory and contradictory evidence;
- producing a “blueprint” to explain how mechanisms in different contexts contribute to outcomes and process variables;
- consulting with key stakeholders to validate findings and test applicability in different contexts;
- disseminating findings through a series of practical tools to support knowledge mobilisation.
The synthesis will employ “best fit” framework synthesis, as a rapid tool by which to facilitate the data extraction and analysis process. The methodology was developed by Carroll et al. (2011) as a pragmatic variation on framework synthesis and is “especially suitable in addressing urgent policy questions where the need for a more fully developed synthesis is balanced by the need for a quick answer” Dixon-Woods (2011). The methodology introduces the deductive step of developing an a priori framework, thus “harnessing the recognised strengths of both framework and thematic synthesis” (Carroll et al., 2013). Best fit framework synthesis will be combined with realist synthesis principles to maximise the value of the interpretative process resulting in practicable and feasible recommendations for practice. Recently, methods have been proposed for rapid approaches to realist synthesis (Saul et al., 2013) and the methods proposed in this review (i.e. synthesis and analysis of logic models and use of a best fit framework) offer an alternative systematic route to harnessing the exploratory potential of the realist lens within an accelerated timescale.
