EBP
Give an example of how to use EBP during assessment?
using prior knowledge acquired from EB research in analyzing assessment data
What type of study is at the top of the evidence ladder?
systematic reviews/meta analysis
The study design characteristic when different people are compared in the study.
between-subjects
Which study design offers the strongest evidence of whether a cause results in an effect?
experimental (such as RCT)
Quasi experiments can lack these two things....
randomization or a control group
Provide two reasons why using EBP is necessary in dental hygiene?
Stay current with up-to-date practice
enhances professional decision making
enhance patient care
This study takes a systematic approach to the selection, assessment and presentation of a number of studies of the same subject.
systematic review
The design characteristic when only the researcher knows who is allocated to which group.
blinding
Identify the study design when outcome data is collected only after the intervention.
retrospective
List an advantage of quasi studies.
May be easier and more practical than true experiments
What is the first step in EBDM?
Ask a concise question
This type of study statistically combines results from several separate studies that identify one answer.
meta analysis
A variable that is extraneous to the research question and interferes with the understanding of the relationship between the independent and dependent variables.
confounding
Identify the study design when the outcome data is collected at baseline and after the intervention.
pre test post test
List a disadvantage of Quasi studies.
–They make it more difficult to infer causality due to the lack of randomization
–Usually there are several alternative hypotheses/reasons for results
List 3 barriers to EBP?
theories
patient values
DH resistant to change
clinical judgement
A study design that follows a group of individuals over a period of time.
longitudinal
The variable that is believed to influence the dependant variable.
independent
What is the main difference between experimental and quasi studies?
randomization
This design is used when pre-intervention and post-intervention data is gathered over a longer period.
time series design
What is the last step in EBDM?
evaluate the process
What are the differences between random sampling and random allocation (assignment)?
Random sampling is about choosing who will be in the study and random allocation is about which group within the study they will be placed in.
Provide the differences between cross sectional and longitudinal.
cross sectional - data collected once
longitudinal - data collected multiple times
What are the 3 key criteria for making casual inferences?
Temporal: The cause must precede the effect in time.
Relationship: There must be an association between the cause and the effect
Confounder: The relationship between the presumed cause and effect cannot be explained by a third variable or a confounder variable
Give one example of when a non-equivalent control group design is suitable.
Cannot randomize the groups due to differing ages of the participants
