Week 3 - Ethics in Research and EBP Flashcards
What is research
It is a systematic inquiry that uses orderly methods to answer a question or solve a problem.
What is nursing research
It is a systematic inquiry designed to develop knowledge about issues of importance of the nursing profession.
nurses do research to solve issues for the patient and it can encompass many topics
What are the scopes of nursing research
scientific approach
applied approach
What are the classifications of nursing research
quantitative research
qualitative research
Scientific Approach
has to do with building the science of the profession of nursing (starts with something like bench research to clinical trials)
Applied Approach
How the information/science is put into practice/populations
What are the 3 interrelated concepts in nursing research which aim to ID, utilize, and apply scientific knowledge from research to clinical practice
- Research Utilization
- Knowledge Translation
- EBP
Research utilization
Applying the information and applying to populations - started in the 70s and 80s
Use of study findings in a practical application in SPECIFIC clinical areas unrelated to original research
Knowledge Translation
acknowledge, take the information, and translate it in a way that is useable (scientific research –> patient care)
Process of synthesizing, disseminating, and using of research knowledge
EBP
Evidence based practice
patient care and patient preferences !!!
Integration of clinical expertise, patient values, and the best research evidence into the decision making process for patient care
How does Research Utilization flow into Knowledge Translation? How does knowledge translation then flow into EBP
Research Utilization: Aims to make an impact on or change in the existing nursing practice –> Knowledge Translation: Bridges the gap in scientific research and its utilization in the delivery of health care services (Stakeholders) –> EBP: Aims to unify research evidence for best decision clinical making
___ causes nursing to move from vocation to profession
EBP
Hx of Research Utilization in Nursing Practice
- Early to Mid 70s: Studies ID’ed Knowledge-Practice Gaps - Nurses were not using research in practice so overall the profession was not using research knowledge
- 80s: CURN Project: Sought to bridge the K-P gap and the Conduct and Utilization of Research in Nursing Project created Research Utilization
- 90s: EBP began to supercede RU
Archie Cochrane and the Cochrane Collaborative
Called for efforts to make research summaries about interventions available to health care providers
These collaborative guidelines aggregate information and studies and rank quality of studies and methods to give overarching guidelines on best available treatment
Part of EBP movement
David Sackett
Developed Evidence Based Medicine which brought in the use of best evidence for all health providers
Would lead to EB Nursing Practice
What exactly is EBP
a life long problem solving approach to clinical practice integrating best evidence, clinical expertise, preferences of the patients
Its a systematic way to be sure that when we care for a patient we incorporate best evidence and pt preferences
What sets EBP apart from best evidence use
PATIENT PREFERENCE incorporation
What things does EBP integrate
search, critical appraisal, and synthesis of the most relevant and best research (external evidence/ best evidence)
ones own clinical expertise, which includes internal evidence generated from outcome management or quality improvement projects, patient assessment and evaluation (clinical expertise/internal evidence)
patient preferences and values
Almost all EBP uses ___ research
quantitative
Best Evidence of EBP comes from …
the findings of quantitative research studies
Clinical Expertise in EBP can include experience and what other things?
Expert Panels
Consensus Statements
Practice Groups
Practitioner Experience
Patient Preferences in EBP include what things
Satisfaction
QOL
Treatment Burden (Is it worth getting treatment for low QOL?)
Qualitative Studies
While most EBP and best evidence comes from quantitative evidence, what can qualitative evidence do?
show us patient preferences and patient experience
Models of the EBP Process
ARCC Model
Diffusion of Innovations Model
Iowa Model of EBP to Promote Quality Care
Johns Hopkins Nursing EBP Model
PARIHS Model
Stetler Model of RU (still uses RU! despite move to EBP)
What are some resources for EBP in nursing
models of the EBP process
preprocessed and pre appraised evidence
What is included under the term pre processed and pre appraised evidence
Clinical practice guidelines
Appraisal of Guidelines Research and Evaluation (AGREE and AGREE II)
most evidence is based in guidelines which are mounted on a ton of research
The 5 Major Steps (As) of EBP
- Ask
- Acquire
- Appraise
- Apply
- Assess
What is step 0 of EBP
0 - Cultivating the Sense of Inquiry
In Organizational settings, EBP must begin by selecting a problem or topic in one of two ways. What are the 2 possible triggers
Knowledge Focused Triggers
Problem Focused Triggers
Knowledge Focused Triggers
Begins with an innovation or research finding (eg: might emerge in a journal club) / something that catches your eye and you look into it
Problem Focused Triggers
Begins with a perplexing or troubling clinical situation
ex: Why are nurses passing out more than they should
Step 1: Ask
Ask: Ask a well-worded clinical question that can be answered with research evidence.
Step 2: Acquire
Search for and retrieve the best evidence to answer the clinical question.
Step 3: Appraise
Critically appraise the evidence for validity and applicability to the problem and situation.
Step 4: Apply
After integrating the evidence with clinical expertise, patient preferences, and local context, apply it to clinical practice.
Step 5: Assess
Evaluate the outcome of the practice change.
When doing step 1: Ask of EBP, what framework is used
PICO - the framework for asking the question
PICO(T) Question
Patient population
Intervention or issue of interest
Comparison intervention or group **
Outcome
Time frame**
** not always specified
What are compared to each other, what is the control, and what is the DV in PICOT
I and C are compared
C would be the control
O is the DV
When asking the question regarding qualitative research what components are looked at
population
situation (processes, exp, cultures, hx, condition of interest)
Ethno, Grounded, Phenom. Key Words
Ethno - Culture
Grounded - Process
Phenom - Experience
Question templates
A template of PICOT that can greatly facilitate wording of questions - can reword article titles to make them make more sense too
ex: In (population), what is the effect of (intervention), in comparison to (comparison), on (outcome) in (timeframe)
After Step 1: Ask, what comes next
Step 2: Acquire research evidence
Can use PICOT as keywords to search the database
find research
What are some databases for Step 2: Acquire of EBP
CINAHL (first line)
MEDLINE
Cochrane Collaboration
Agency for Healthcare Research and Quality**
National Guideline Clearinghouse**
** good place to look for clinical practice guidelines and is directly applicable to clinical practice
Step 3: Appraise the evidence involves what factors
Quality
Magnitude
Quantity
Consistency
Applicability
Level of Evidence
Quality (Step 3)
to what extent is the evidence valid- how serious is the risk of biases in this research?
Magnitude (Step 3)
How large is the effect of the intervention or influence (I) on the outcome (O) in the population of interest (P)? Are the effects clinically significant?
Is it significant enough to change behavior and practice to improve care
Quantity (Step 3)
How much evidence is there? How many studies have been conducted, and did those studies involve a large number of participants?
Consistency (Step 3)
How consistent are the findings across various studies?
We want to see consistent agreement across studies
Applicability (Step 3)
To what extent is the evidence relevant to my clinical situation and patients?
How well can this apply to care bedside, community care, large groups, family care
The key question during Step 3: Appraise is?
Applicability of research
Level of Evidence
Pyramid of evidence levels that is applicable to research appraisal by seeing where the study falls in regard to what type and level of evidence it is
it looks at the level of study design
7 Levels
Evidence Level 1
Systematic Review of RCTs and nonrandomized trials / Reviews of Literature and Studies
Quantitative evidence
Considered the highest level/ best level
Evidence Level 2
Experimental Controlled Trials or Quasi Experimental Studies - Quantitative evidence
Evidence Level 3
Systematic Reviews of NON experimental studies - still quantitative evidence
Evidence Level 4
Individual Correlational Observational Studies
Still quantitative
