Week 1-3 Lecture and Review Flashcards
What is the first step in the evidence informed practice framework?
Ask a well framed clinical question
What is the second step in the evidence informed practice framework?
Gather
What is the third step in the evidence informed practice framework?
Assess/Appraise
What is the fourth step in the evidence informed practice framework?
Act
What is the fifth step in the evidence informed practice framework?
Evaluate
What are the five components of a clinical question?
(PICOT Format)
Population
Intervention
Comparison
Outcome
Time
What are the five components of the SPIDER tool?
(Spider tool)
S: Sample
PI: Phenomenon of interest
D: Design
E: Evaluation
R: Research type
(Tool adapted from PICOT)
Where do research questions come from?
- Lots of times they come from unanswered clinical questions where there isn’t substantial evidence
- Desire to improve patient/population outcomes
- Practice issues e.g. workplace bullying
Define research question
A concise, interrogative statement written in the present tense and including one or more variables/concepts
(it needs to have at least three components to be useful; variables, population being studied, examining testable relationships among variables)
What do research questions focus on?
- Describing variables
- Specifying the population being studied
- Examining testable relationships among variables
Define independent variable (X)
Independent variable (X) - the variable that has the presumed effect on the dependent variable (Y)
Define dependent variable (Y)
Dependent variable (Y) - the presumed effect that varies with a change in the independent variable (X)
- It is not manipulated
Describe population
- the population is a well-defined set that has certain properties
- it is either specified or implied in the research question
What does PICOT stand for?
Population, intervention, comparison, outcome, time
What is a hypothesis?
A hypothesis is something that states a prediction and must involve at least two variables
Describe a simple hypothesis
Expresses a predicted relationship between one independent variable and one dependent variable
What is the difference between a simple and complex hypothesis
the number of variables
Describe a complex hypothesis
States a predicted relationship between two or more independent variables and/or two or more dependent variables
Describe a research hypothesis?
It states the actual prediction of a relationship
Describe a statistical or null hypothesis?
It expresses the absence of a relationship between variables (used only in statistical testing; you will not see a null hypothesis written in a research paper)
The SPIDER tool is best suited for what types of research?
qualitative and mixed method research
Define research
Research is the systematic, rigorous, logical investigation with the aim of answering questions about nursing phenomena
Define phenomena
Phenomena can be defined as occurrences, circumstances, or fact that are perceptible by the senses. Can often be experiences that are not easily observed (but can be explored/described).
What is research?
A structured process for gathering and synthesizing facts and theories
What are some characteristics of good research?
- Systemic and objective
- Valid and reliable
- Scientific method
- Dynamic and creative (it evolves)
- Examines conditions and outcomes
- Purpose is to improve methods of practice
- Done ethically
Define (research) quality/rigour
the extent to which a study’s design, implementation and analysis minimizes bias
Define (research) quantity
the number of studies in which the research question has been evaluated, including overall sample size across studies as well as strength of the findings from the data analyses
Define (research) consistency
the degree to which similar findings are reported from investigations of the same research question in studies that have similar and different designs
What is critical appraisal?
the assessment of a study’s methodological quality - taking into consideration:
- it’s validity (is it true? does it represent reality?)
- it’s results (statically/clinically significant? replicable?)
- it’s relevancy (aka utility in clinical practice)
What is the significance of research to nursing practice?
- expands the discipline’s unique body of scientific knowledge
- forms the foundation for evidence-informed nursing practice
- allows practice to change with work environments and the most common health issues
- maintains the profession’s societal relevance
