The Haynes 5S ModelProposed by Dr. Brian Haynes of McMaster University, Hamilton, Ontario,

Canada.

Intent is to provide directed support in the search for EBP resources.

The model represents the amount of resources available in different areas, the most numerous and easily accessible being those single-topic studies found at the base of the pyramid.

The further up the pyramid one goes, the number of resources lessens as does the free/open accessibility to them.

The suggestions for “Where to find” the resources are just that and are intended to serve as good starting points. This guide was created to assist the nursing students of Valparaiso University.

The Haynes 5S Model

5S Model: Single Studies

• The original journal articles that present the entire report of one study on one aspect or management of a health problem.

• Clinical trials that are very focused also offer this type of information.

Synopses

5S Model: Syntheses

• Usually called “systematic reviews” in the research literature

• Some databases allow you to limit search results by using that term in the search strategy.

Synopses

5S Model: Synopses

• Very brief descriptions of original articles and reviews

• Often read as if they are a lit review for the topic

• Often found termed as “meta- analysis”

5S Model: Summaries

Summaries integrate the best available evidence to provide full range of evidence addressing all management options for a given health problem, not just one aspect of the problem (as found in single-study resources that make up the lower three categories in the 5S Model).

Systems are very detailed, often patient-specific, linking the patient’s conditions to current best practices.
