Finding and Appraising Existing Systematic Reviews
One of the initial phases of conducting a systematic review is to assess the need for one on your chosen topic. You need to determine if there are existing published reviews, if so, do they meet quality criteria and do they need to be updated? Even though a systematic review has been published, that doesn't mean that it is of good quality. There are tools that you can use to determine if it truly meets the standards of rigor and reproducibility.
This set of eight critical appraisal tools are designed to be used when reading research, these include tools for Systematic Reviews, Randomised Controlled Trials, Cohort Studies, Case Control Studies, Economic Evaluations, Diagnostic Studies, Qualitative studies and Clinical Prediction Rule.
