Although the two requirements have the potential for overlapping concepts in the minds of many nurses, evidence-based practice and research projects are distinctly different—and, if the differences are not recognized, it is possible for an organization's documentation to fail to adequately explain how it meets both requirements. Evidence-based practice What is evidence-based practice in the most basic terms?
Evidence-based practice looks at research findings, quality improvement data and other forms of evaluation data, and expert opinion to identify methods of improvement. It's identifying what exactly differentiates evidence-based practice from research that can be challenging for staff members.
Evidence-based practice challenges nurses to look at the "why" behind existing methods and processes in the search for improvement. All of the various hierarchies of evidence are similar to some degree. Once the evidence is gathered, the researcher must critically appraise each study to ensure its credibility and clinical significance. Critical appraisal often is thought to be tedious and time-consuming.
An easy method for conducting critical appraisal is to answer these three key questions:. Disseminating or reporting the results of EBP projects may help others learn about and apply the best evidence. Examples of potential EBP projects include implementing an evidence-based clinical practice guideline to reduce or prevent CAUTIs, evaluating an evidence-based intervention to improve wound healing, and applying an EBP to improve compliance with a specific treatment for a chronic disease.
The purpose of QI is to use a systematic, data-guided approach to improve processes or outcomes. Principles and strategies involved in QI have evolved from organizational philosophies of total quality management and continuous quality improvement. While the concept of quality can be subjective, QI in healthcare typically focuses on improving patient outcomes. So the key is to clearly define the outcome that needs to be improved, identify how the outcome will be measured, and develop a plan for implementing an intervention and collecting data before and after the intervention.
O rganize an effort to work on improvement. C larify current knowledge of the process. U nderstand process variation and performance capability. S elect changes aimed at performance improvement. P lan the change; analyze current data and predict the results. S tudy analyze the new data and check the results.
Examples of QI projects include implementing a process to remove urinary catheters within a certain time frame, developing a process to improve wound-care documentation, and improving the process for patient education for a specific chronic disease.

Research concentrate more on new knowledge and validating that existing knowledge based on a theory, while EBP is using the best evident to improve patient outcome and finally QI actually uses a systematic approach to improve the outcome.
