EBN is a process founded on the collection, interpretation, appraisal, and integration of valid, clinically significant, and applicable research. The evidence used to change practice or make a clinical decision can be separated into seven levels of evidence that differ in type of study and level of quality. To properly implement EBN, the knowledge of the nurse, the patient’s preferences, and multiple studies of evidence must all be collaborated and utilized in order to produce an appropriate solution to the task at hand. A spirit of inquiry refers to an attitude in which questions are encouraged to be asked about existing practices. Cultivating a spirit of inquiry allows healthcare providers to feel comfortable with questioning current methods of practice and challenging these practices to create improvements and change. A culture that fosters this should have a philosophy that incorporates EBP, access to tools that can enhance EBP, and administrative support and leadership that values EBP.
Always question current practices as nursing professional. EBP mentors for skills and knowledge availability to others to provide and help. Higher level support and ability for leaders to model valued EBP skills. Asking questions in this format assists in generating a search that produces the most relevant, quality information related to a topic, while also decreasing the amount of time needed to produce these search results. To begin the search for evidence, use each keyword from the PICOT question that was formed. Once results have been found on the intervention or treatment, the research can be rated to determine which provides the strongest level of evidence.
The strongest levels of evidence, systematic reviews and meta-analyses, summarize evidence related to a specific topic by finding and assessing studies that specifically relate to the question being asked. Meta-analyses are systematic reviews that also use quantitative measures such as statistics to summarize the results of the studies analyzed. Thinking of the information resources used to obtain evidence as a pyramid can help determine what the most valid and least biased evidence is. The top of the pyramid is just that. This is where decision support can be found, which is found within the medical record. The middle of the pyramid is the reviews of the evidence. This includes systematic reviews, practice guidelines, topic summaries, and article synopses.
The bottom of the pyramid is the original studies. The bottom is also considered the foundation of the pyramid and where evidence begins. Those who look for evidence here need special knowledge and skills to not only find the evidence itself but how to evaluate its worthiness. To begin the critical appraisal process, three questions need to asked to determine the relevance of evidence and if evidence applies to population being cared for. Are the results of the study valid? Will the results be applicable in caring for patients?
