10. Implement and evaluate
Evidence-based Pyramid
,Types of evidence assigned by level:
Top (best evidence) to bottom
1.) Meta-analyses & systematic reviews
2.) Evidence-Based reviews
3.) Randomized control trials
4.) Case-control studies, case series, case reports
5.) Textbooks, review articles, expert opinions & laboratory research
Qualitative Research
Empirical research where the data are not in the form of numbers. Research is multimethod in
focus, involving an interpretive, naturalistic approach to its subject matter. Researchers study
things in their natural settings, attempting to make sense of/interpret phenomena in terms of the
meanings people bring them.
qualitative information
Involves a descriptive judgement using concept words instead of numbers.
Quantitative Research
Gathers data in a numerical form which can be put into categories, or in rank order, or measured
in units of measurement. This type of data can be used to construct graphs and tables of raw data.
Researchers aim to establish general laws of behavior/phenomenon across different
settings/contexts. Research is used to test theories and ultimately support or reject it.
quantitative information
, Involves a measurable quantity- numbers are used. For example: Mass, temperature, time,
length. Often called data, but can be things other than numbers.
case study
The study of a bounded system (a case or multiple cases) over time through detailed, in-depth
data collection involving multiple sources of information.
case report
commonly used qualitative research strategy. Another name for case study. Serves two functions:
sharing information and supporting learning in an area of healthcare.
Observational research style
Quantitative research style: quantifies phenomena, but it does not involve the use of an
intervention.
Experimental research style
Quantitative research style: involves dividing patients randomly, selecting subjects from the
entire population or randomly assigning participants into intervention and control groups, and
measuring differences between them or associations between predictor and response variables.
Retrospective research style
Quantitative research style: examines an outcome or exposure that has already occurred and
utilizes numerical data to test for relationships between variables or differences between groups
that can be associated with the phenomenon.
Prospective research style
