Preappraised Evidence Guidance
Acquiring the best evidence can be daunting with numerous textbooks and guidelines, millions of studies in PubMed and many other sources. Fortunately, resources to overcome such information overload and provide rapid access to valid clinical knowledge continue to evolve.
Below is the pyramid to display "preappraised evidence guidance." The linked article (Alper et al., 2016) explains the rationale.

Clinical Guideline Resources
“Clinical practice guidelines are systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances.”(Institute of Medicine, 1990)
Since the demise of the National Guideline Clearinghouse in 2018, there are less centralized locations for clinical practice guidelines. Below is a brief list of US guideline repositories. International guideline repositories are listed on the Practice Guidelines page of the Clinical Professional research guide.
