Qualitative evidence synthesis
Transcript of Qualitative evidence synthesis
SIGN (Ovid Medline) http://www.sign.ac.uk/methodology/filters.html#patient They used the Health Belief Model as a starting point for developing codes and as a conceptual lens to assess the themes If there is no theory, then thematic synthesis No theory, no panic Carroll & Booth (2011, revisited in 2013) Best fit Question: what if the framework(s) available aren't a great fit?

The Vitaldía Project, Bolivia; 2002. Adapt model to patient views of colorectal cancer chemoprophylaxis (no previous model found) Creation of a new conceptual model Lessons learned There were "helpful overlaps" The original model lacked adequate depth & complexity, relationships poorly-defined Finding a model using Google Scholar: (model$ or framework$ or theoretical or theory or concept or conceptual) - needs some refinement! a priori themes - lack of team consensus Baxter et al. (2011) 59 studies retrieved and analysed to yield 7 themes This quantity of research lends itself well to superficial categorisation and description "several smaller, more targeted searches to identify evidence" Like a really good literature review or narrative SR? Pop quiz! 1. You are interested in health consumer behaviours. You find 45+ papers, have limited time, and you want to build a theory, which method do you choose (thematic, framework or best fit)? 2. You want to examine 'fear of being judged' as a barrier to seeking dental treatment in meth addicts. No previous review has explored this. There are less than 4 relevant studies. Your review will help public health workers gain a better understanding of this barrier.
