AbstractFrom the searches presented, it can be seen that there are times when scientific studies will not be available to answer burning clinical questions. If systematic reviews, evidence-based guidelines, and individual studies are not available, clinicians must then turn to expert anecdotal evidence to guide their decision-making process and interventions. As further randomized controlled trials are conducted to evaluate nursing interventions, more scientific evidence will become available to guide nursing practice. However, it is important to remember that EBP not only encompasses evidence from research and its appraisal, but also includes patient preferences and expertise by the clinician. Because a meta-analysis indicated that patients had 28% better outcomes when nursing interventions were based on scientific evidence rather than interventions that were steeped in tradition (Heater, Becker, & Olson, 1988), it is essential that nurse practitioners and nurses have the appropriate knowledge and skills to translate evidence from research into practice. Asking searchable questions and knowing how to search for and find the best evidence are two key steps in delivering the highest quality of evidence-based nursing care to patients and their families.
