This might seem a really obvious question but it’s one I really struggle with. So, this post is a request for help! Note: the post relates to systematic reviews of individual interventions as opposed to the broader outcome-focussed systematic reviews (e.g. what’s effective in helping people quit smoking?) I get the impression that people embark on systematic reviews with little thought to the reasons behind the review; … Continue reading Why do we do systematic reviews?

Yesterday was the last day of a really interesting two-day symposium on automation and systematic reviews in Bristol. The main participants were computer scientists and systematic reviewers; I belonged in the relatively small ‘other’ group. It struck me that the focus was on breaking down the steps of systematic reviews (as seen in a few papers, one reviewed on this blog – click here) and … Continue reading Two main fronts on the speeding up of systematic reviews
In 2014 Guy Tsafnat, Paul Glasziou and others wrote the paper Systematic review automation technologies where the authors “…surveyed literature describing informatics systems that support or automate the processes of systematic review or each of the tasks of the systematic review.“ It is an excellent overview of the potential of automation in the systematic review process. They do this by breaking down the systematic review … Continue reading Article review: Systematic review automation technologies

The first article was published in April 2012 and was a list of articles that compared rapid versus systematic methods.
