The basis of evidence-based practice in nursing is the ability to find and use the best possible or highest level of evidence from quality research studies to make clinical decisions. Studies are hierarchically grouped into various levels of evidence depending on the methodological quality of the studies' applicability to patient care, validity, and design. Levels of evidence range from I to VII.

Generally, quasi-experimental designs are examples of approaches to quantitative research which seek to establish a cause-effect relationship between variables.

2. Where does your study fall on the levels of evidence hierarchy? Explain.

The studies fall on Level VIII of the evidence hierarchy. Often, level VIII consists of evidence acquired from quasi-experimental studies with well-deisgned controlled trials that lack randomization. This study uses a longitudinal quasi-experimental design in assessing the effectiveness of a collaborative multi-strategy fall risk management program in reducing patient falls in a nursing facility.


In conclusion, the level of evidence hierarchy provides a concise classification of evidence from research studies based on the strength and quality of their designs and validity, hence helping inform nursing practice and decision making. The learning point from this paper is that while conducting research on any practicum issue in nursing or healthcare in general, one has to first determine which level in the evidence pyramid it belongs as this will determine its applicability to a healthcare setting.
