definition of EBP
integrate best current evidence with clinical expertise and patient/family preferences and values for delivery of optimal healthcare.
EBP - historical development and role in modern nursing
Florence Nightingale – founder of modern nursing practice. Identified the role of a nurse on a healthcare team. She recognized the importance of sanitation and nutrition, fresh air – these are helpful in the healing process. She measured client outcomes/data and compared before and after of nursing interventions
EBP purpose & focus
purpose - foundation for implementing effective/efficient healthcare that relies on scholarly research that nurses evaluate and incorporate.
EBP who conducts and association with clinical practice
scientists and those in the field
investigating something (patient’s question) through research and QI.
Research purpose and focus
advance nursing practice through the discovery of new information
more complex evidence through scientific data, behind the scenes work
research who conducts and association with clinical practice
scientists/researchers
finding data that can then be applied through EBP
QI definition and focus
uses measurable data to advance/improve healthcare services and outcomes
directly in the practice
QI who conducts and association with clinical practice
those in the setting (nurses, supervisors, nurse scientists working within a facility)
within the setting, making/changing policies, and reevaluating those changes
4 key components of EBP
- Best available evidence
- Clinical expertise
- Patient values/preferences
- Value of research in comparison to info found by other sources: more applicable, reliable, based upon real practices in the nursing setting, research is more rigorous and has actual data - increasing validity
7 steps of EBP
- Encourage/Supporting the spirit of inquiry
- Asking questions
- Searching for evidence
- Appraising the evidence (assessing research quality and relevance)
- Integrating research evidence into clinical decision making
- Evaluating outcomes
- sharing the results - dissemination
PICOT questions
Patient/population/problem
intervention
comparison
outcome
time
quantitative vs qualitative
quant - numbers, stats - objective data
qual - experiences, perceptions, finding themes - subjective data
Randomized-control trials
uses intervention and control groups to compare
systematic reviews
answers a specific research question by evaluating all the studies on that topic
meta-analyses
uses statistical methods along with systematic reviews combining the results from existing research
how does EBP improve patient outcomes and nursing performance
EBP is based on evidence so it would enhance patient outcomes, decrease mortality, increase care practices. Examples include hand washing, pain management, and fall prevention
