Evidence-based practice is a problem-solving approach to making decisions about patient care that is grounded in:
a. The latest information found in textbooks
b. Systematically conducted research studies
c. Tradition in clinical practice
d. Quality improvement and risk management data
B
The best evidence comes from well-designed, systematically conducted research studies found in scientific journals. Portions of a textbook often become outdated by the time it is published. Many health care settings do not have a process to help staff adopt new evidence in practice. And nurses in practice settings lack easy access to risk management data, relying instead on tradition or convenience.
Some sources of evidence do not originate from research. These include quality improvement and risk management data; infection control data, retrospective or concurrent chart reviews; and clinicians' expertise. Although non–research-based evidence is often very valuable, it is important that you learn to rely more on research-based evidence.
