Study Notes

Importance of EBM

Many important questions still do not have adequate evidence to inform clinical decision-making.

Pharmacists and EBM

Pharmaceuticals are an important therapeutic resource.
It is easier to convince providers when recommendations are supported by EBM.

Types of Literature

Primary Literature

Original research studies that collect data
Outcomes and conclusions may be misleading if based on a single study
Must be carefully evaluated

Secondary Literature

Describes, summarizes, and discusses information from another source
Includes commentaries on EBM
Examples: reviews, meta-analyses, and guidelines

Tertiary Literature

Not specified in the text, but generally refers to syntheses of secondary literature

Grey Literature

Not specified in the text, but generally refers to reports, theses, and other documents not published commercially

Evaluating Studies

The quality of evidence in a study is important
The strength of inference from a study is crucial
Level of bias in a study must be considered
