What are filtered and unfiltered resources in nursing?

Filtered and unfiltered resources are differentiated by the level of evaluation the resource has undergone.
 

Filtered resources have been evaluated for their quality, and often contain recommendations for practice. Examples include:

• systematic reviews

• meta-analyses

• critically-appraised topics

• critically-appraised individual articles

Unfiltered resources are primary or original research studies. Examples include:

• randomized controlled trails

• cohort studies

• case studies
