An introduction to evidence-based practice

Evidence-based practice (EBP) is a process in which scientific evidence is evaluated to determine underlying trends and principles of health/health care. This information is then translated into information about best clinical practices. EBP affords a systematic way to improve healthcare, improve patient outcomes, and evaluate resources needed. The Star Model of EBP provides a mechanism to transform large collections of research data into clinical practice. The 5 steps of knowledge production through original research, evidence summary, evidence translation, implementation, and evaluation differ from the traditional methods for research utilization. A number of groups are currently summarizing research on a wide variety of topics, providing conclusions about the state of the science. The nurse can access these valuable summaries of clinical knowledge as a crucial step in moving research into practice. The use of research evidence in our care increases certainty and predictability in the effect of the practice on the outcome.
