The library research skills you learn over the course of your education in nursing should follow you beyond the classroom and into "real-life" in the form of evidence-based practice.
What is Evidence-Based Practice?
The most widely used definition for evidence-based practice is from Sackett et al. (1996): "[EBP] is the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients. The practice of evidence base medicine means integrating clinical expertise with the best available external clinical evidence from systematic research." More recent definitions of EBP include patient values in addition to clinical expertise and evidence from research.
