INTRODUCTION. The nursing research pyramid, or nursing research hierarchy of evidence, provides a visual and systematic depiction of forms of research from the least reliable (base) to the most reliable (apex). The pyramid includes both qualitative and quantitative paradigms.

What type of study would be at the top of a hierarchy of evidence sources?

In most evidence hierachies current, well designed systematic reviews and meta-analyses are at the top of the pyramid, and expert opinion and anecdotal experience are at the bottom.

Where does a cross sectional study fit in the hierarchy of evidence?

Cross sectional study designs and case series form the lowest level of the aetiology hierarchy. In the cross sectional design, data concerning each subject is often recorded at one point in time. For instance, a questionnaire might be sent to a district where forestry is a predominant industry.

Why is hierarchy of evidence important?

The hierarchy provides a guide that helps the determine best evidence; however, factors such as research quality will also exert an influence on the value of the available evidence.

How to rate the Quality of Evidence (your confidence in the effect estimate) High: We are very confident in the evidence supporting the recommendation. Further research is very unlikely to change the estimates of effect. Moderate: We are moderately confident in the evidence supporting the recommendation.

How do you evaluate quality of evidence?

What to doPlan your approach to assessing certainty. Consider the importance of outcomes. Assess risk of bias (or study limitations) Assess inconsistency or heterogeneity. Assess indirectness. Assess imprecision. Assess publication biases. Consider reasons to upgrade the certainty of the evidence.
