National Guideline Clearinghouse (NGC)


National Guideline Clearinghouse (NGC)


This Web-accessible database provides access to evidence-based clinical practice guidelines. The National Guideline Clearinghouse’s (NGC’s) mission is to provide physicians, nurses, health care providers and professionals, health plans, integrated delivery systems, purchasers, and others an accessible mechanism for obtaining objective, detailed information on clinical practice guidelines and to further their dissemination, implementation, and use.

Key components of NGC include:

  • Structured abstracts (summaries) about the guideline and its development
  • Links to full-text guidelines, where available, and/or ordering information for print copies
  • Palm-based PDA downloads of the complete NGC summary for all guidelines represented in the database
  • A guideline comparison utility that gives users the ability to generate side-by-side comparisons for any combination of two or more guidelines
  • Unique guideline comparisons called guideline syntheses prepared by NGC staff, which compare guidelines covering similar topics and highlighting areas of similarity and difference. NGC guideline syntheses often provide a comparison of guidelines developed in different countries, providing insight into commonalities and differences in international health practices
  • An electronic forum, NGC-L for exchanging information on clinical practice guidelines, their development, implementation, and use
  • An annotated bibliography database where users can search for citations for publications and resources about guidelines, including guideline development and methodology, structure, evaluation, and implementation
  • An expert commentary feature written/reviewed by the NGC/National Quality Measures Clearinghouse Editorial Board
