NR439 Week6 Early Pressure Ulcer Prevention



Nurses make clinical decisions based on information gleaned from a variety of sources, including coursework, textbooks, and their own clinical experience. Learning about best practice nursing continues throughout a nurse’s career because evidence is constantly evolving.

Some of what nurses learn is based on systematic research, but much of it is not. What are the sources of evidence for nursing practice? Where does knowledge for practice come from? Until fairly recently, knowledge primarily was handed down from one generation to the next based on experience, trial and error, tradition, and expert opinion. Information sources for clinical practice vary in dependability, giving rise to what is called an evidence hierarchy, which acknowledges that certain types of evidence are better than others. A brief discussion of some alternative sources of evidence shows how research-based information is different.

Tradition and Authority

Decisions are sometimes based on custom or tradition. Certain “truths” are accepted as given, and such “knowledge” is so much a part of a common heritage that few seek verification. Tradition facilitates communication by providing a common foundation of accepted truth, but many traditions have never been evaluated for their validity. There is concern that some nursing interventions are based on tradition, custom, and “unit culture” rather than on sound evidence. Indeed, a recent analysis suggests that some “sacred cows” (ineffective traditional habits) persist even in a health care center recognized as a leader in evidence-based practice (Hanrahan et al., 2015).

Another common source of information is an authority, a person with specialized expertise. We often make decisions about problems with which we have little experience; it seems natural to place our trust in the judgment of people with specialized training or experience. As a source of evidence, however, authority has shortcomings. Authorities are not infallible, particularly if their expertise is based primarily on personal experience; yet, like tradition, their knowledge often goes unchallenged.
