Exam 1: EBP
Boolean Operators
Words such as "and," "or," "not," and "near" that are used to combine search
terms in electronic evidence databases and other search engines.
Clinical practice guidelines
". . . statements that include recommendations intended to optimize patient care.
They are informed by a systematic review of evidence and an assessment of the
benefits and harms of alternative care options."1; also referred to as
"summaries."
Keywords
The word(s) or term(s) that is/are entered into an electronic database search
function to locate evidence pertaining to a clinical question
MeSH
Abbreviation for "Medical Subject Heading"; the term used to describe approved
search vocabulary in the U.S. National Library of Medicine electronic database
(PubMed); the MeSH vocabulary also may be used by other electronic evidence
databases.
Search String
A combination of keywords, phrases, names, or other information that is entered
into an electronic database search function to locate evidence pertaining to a
clinical question.
Secondary sources
Textbooks, summaries on websites, and review papers that contain information
based on primary sources of information.
,Research design
Refers to the overall strategy that you choose to integrate the different
components of the study in a coherent and logical way
The function of research design
Ensure that the evidence obtained enables you to effectively address the
research problem in the best way possible
The research design and different components of the study are described in a...
Study protocol
Two major types of research design?
1) experimental
2) Non-experimental/observational
Experimental designs types
1) RCT: random control times
2) Quasi-experimental
Non-experimental/observational design types
1) cross-sectional
2) cohort
3) case control
syntheses of evidence
1) systematic review
2) systematic review and meta analysis
Formal descriptions of practice
, 1) single subject case report
2) case series
Design features:
1) number of groups
2) control elements
3) the role of time in the study
Hierarchies of evidence is underpinned (reflected) by
The study's research design-and the chosen design's effect on bias control
Bias refers to
The systematic deviation from the truth that occurs as a result of uncontrolled
(and unwanted) influences during the study
Bias control continuum
Most to least bias CONTROL:
1) experimental design
2) quasi-experimental design
3) non experiential designs
4) case report/anecdote
Gold standard of clinical research
Experimental design = randomized controlled trial
RCT (randomized controlled trial) is best suited to answer questions about:
1) whether an intervention has an effect
2) if one intervention is better than another
3) whether an intervention is beneficial or harmful
