National Guideline Clearinghouse Is No More: Keep Calm and Search On.

In July 2018, the National Guideline Clearinghouse lost funding, leaving fewer freely available online guideline collections. Based on the authors' experience of the 3 major guideline-focused databases that are currently available (Guidelines International Network, the Turning Research into Practice database, and Guideline Central) an easy to use resource with stringent inclusion criteria is currently lacking, though new resources are in development. These 3 resources vary in scope, and none stood out as an all-encompassing favorite. Regardless of the source used to find and access guidelines, clinicians must evaluate guideline quality and currency before using them in clinical practice.
