I like Andrew’s definition and point about bias, and this definition points to the type of expanded scope that people like Trisha and and Jennie Popay have influenced over the years. However, I think that it is still useful to refer to ‘traditional SR’, that relies on a hierarchy of evidence (with RCTs at the top) and has an explicit aim of quantitative meta-analysis of outcomes data to asses effectiveness and safety of well-defined interventions. I say this because it is still useful to make a contrast between different approaches to SR, and certainly to contrast approaches that exclude context and have a black box approach that takes into account only inputs (well-defined interventions) and outcomes, with approaches that take context as a central object of analysis and synthesis, as realist reviews do.

 

Cheers, Simon

In your position Becky I would probably go outside healthcare for a definition. So for example Environmental Evidence uses the following:

 

"A systematic review is a review of evidence relevant to a clearly formulated question that uses systematic and explicit methods to identify, select and critically appraise relevant research, and to collect and analyse data from the studies that are included within the review". 

 

However I must say that for me the defining characteristic of a systematic review is the use of "strategies to limit bias" (as in the classic Epidemiology definition by Last) because while some may argue about how "bias" should be interpreted within qualitative evidence, for example, it seems to me that if you weren't trying to limit bias then it seems an awful lot of extra trouble to go to!

My fellow RAMESESIANS,

 

I am hoping you could help me with the following.

 

I have recently had a bit of constructive feedback in the way I have defined the traditional-Cochrane- style systematic review.  My description of the SR as a method that produces pass/fail judgements on programmes lacks

 nuance and does not reflect the progress that has been made in the field of SR.

 

I was wondering if anyone could point me in the right direction of some relevant references that could help bring my definition of a SR up to date.

 

Many thanks

 

Becky
