Last week, you explored quantitative inquiry and data. This week, you’ll have the opportunity to investigate summaries of multiple research studies, including systematic reviews. In the hierarchy of evidence quality, systematic reviews of randomized controlled trials are considered the gold standard of evidence. During this week you’ll learn how to appraise systematic reviews and other summaries of multiple studies using the Johns Hopkins Nursing Evidence-Based Practice Research Evidence Appraisal Tool. I bet you’re getting familiar with this tool after applying it in Weeks 1 and 2. 
Complete your own appraisal of a systematic review using the John Hopkins Nursing Evidence-Based Practice Research Evidence Appraisal Tool. This appraisal tool is used to evaluate qualitative, quantitative, and mixed methods research. Use Section I (part B) of the tool to appraise a systematic review. Select one of the eight practice problems that burden the overall health of the United States*use as the previous week (substance abuse disorders). 
Conduct a library search for one systematic review (without meta-analysis; with meta-analysis; meta-synthesis) addressing this problem. Appraise the systematic review using the Johns Hopkins Research Evidence Appraisal Tool. After appraising and determining the Level of Evidence and Grade of Quality for your selected systematic review, summarize your findings. Transfer your findings to the Johns Hopkins Individual Evidence Summary Tool. Complete each column including specific details about the systematic review.
Include your completed Johns Hopkins Individual Evidence Summary Tool and your systematic review as an attachment with your initial post. Also, include a permalink for your selected systematic review with your initial discussion post. Confirm the link allows access to the full-text study article. Our faculty team will review both your research study and Johns Hopkins Individual Evidence Summary Tool and provide guidance.
Analyze the evidence summary of the selected systematic review to address the following.
– Does the research design answer the research question? Explain your rationale.
– Were the study sample participants representative? Why or why not?
– Compare and contrast the study limitations in this study.
– Based on this evidence summary, would you consider this systematic review as support for your selected practice problem? Explain your rationale. 
– How does an integrative review, meta-analysis, systematic review, and meta-synthesis differ?
