Meta-analysis and systematic review are essential for evidence-based practices as they allow you to compare the findings of several studies to understand what impact an intervention may have on outcomes. Researchers can use systematic reviews to conduct a rigorous search of the literature and identify relevant articles, while also checking for any biases in drawing conclusions. Meta-analyses, on the other hand combine data from multiple sources to arrive at more accurate estimates. This helps practitioners make decisions using existing research.

Both methods have their limitations, such as the lack of standardization across databases and a dependence on self-reported information that could lead to a reduction in accuracy. Researchers must use reliable and valid search methods, along with strategies such as sensitivity analyses to detect inconsistencies in their data. By combining systematic reviews, meta-analyses and traditional inquiry methods with current evidence, practitioners will be able to gain insights into the best ways to deliver interventions and programs.
