Evidence Based Practice Flashcards
What are the three tenants of Evidence Based Practice?
- Best Scientific Evidence
- Clinical Expertise
- Patient Values
What is the Highest Form of Evidence?
Meta Analysis and Systematic Reviews
(Gold Standard of Clinical Information)
What is the Lowest for of Evidence?
Case Series/Case Reports
What has a better level of evidence? Cohort studies or case control studies?
Cohort Studies
What is a Randomized Controlled Trial (RCT)
Determining the efficacy of intervention.
Always have 2 groups
- one group that receives the intervention
- one group that does not receive the intervention. (Control Group)
What is a Cohort?
A group of individuals who share a common characteristic.
How does randomization help with research?
Helps with controlling bias.
What are Cohort Studies?
Observational studies only, with a group of patients with a similar characteristic
What is a Case Control Study?
Compares a group of individuals with a condition with a group without the same condition.
Patients with covid vs patients without covid.
What is a Cross Sectional Study?
Observational study where the investigator measures the outcome at a single point time.
What is a longitudinal study?
Observational study that measures outcomes over a period of time.
What is a Retrospective Cohort?
Data collected from the past
What is a Prospective Cohort?
Data collected in the future
What is Qualitative Research?
Collecting and analyzing non-numerical data
- Subjective
- Emotions
- Perspective
What is Quantitative Research?
Collecting and Analyzing Numerical Data?
Can a Statistical Analysis be performed on Qualitative Data?
Cannot be performed as these are not numbers
What is Nominal Data?
Data: Labelled or classified into categories. (Nominal = Naming)
- used to label variables without quantitative value
- Mutually exclusive data (cannot be blood type A and B is one or the other)
Examples of Nominal Data?
- Gender
- Blood Types
What is Ordinal?
- Ranking/Order
- No quantifiable difference between ranks
Examples of Ordinal Data?
- MMT
- Levels of Assistance
- Joint Laxity Grades
Is Nominal and Ordinal Data Parametric or Non-Parametric?
Non-Parametric
(NOn-Parametric)
- N Nominal
- O Ordinal
What is Interval?
- The difference between to values is meaningful
- No true zero, can represent values below zero
Interval Data Examples?
- Temperature
- IQ
Zero degrees does not mean no temperature.
What is Ratio?
- All properties of interval data.
- Has a true zero
RatiO = True 0
