Evidence-Based Practice

Evidence-based practice is a way of providing health care that is guided by a thoughtful integration of the best available scientific knowledge with clinical expertise. This approach allows the practitioner to critically assess research data, clinical guidelines, and other information resources in order to correctly identify the clinical problem, apply the most high-quality intervention, and re-evalutate the outcome for future improvement (from Medline). 

Different Types of Studies:

• Meta-Analysis
• Systematic Review
• RCT (Randomized Controlled Trial)
• Cohort
• Case Control 
• Cross-sectional
• Case Series/Reports

The instructions will show you step-by-step how to find Meta-Analysis and Systematic Review.

Meta-analysis: examination of data from a number of independent studies of the same subject, in order to determine overall trends. 

Systematic Reviews: A systematic review attempts to identify, appraise and synthesize all the empirical evidence that meets pre-specified eligibility criteria to answer a specific research question. Researchers conducting systematic reviews use explicit, systematic methods that are selected with a view aimed at minimizing bias, to produce more reliable findings to inform decision making.
