Often, specific guidelines can only be retrieved through local websites of scientific associations or government agencies. It is therefore recommended to combine a Medline search (with specific filters for guidelines) with a search of the following:
- National Guideline Clearinghouse (NGC): a US-based database of clinical practice guidelines primarily in the English language; free access
- International Guideline Library (G-I-N): database of the Guideline International Network (KCE is member of GIN and has full access to the records)
- EBMpracticenet: DUODECIM guidelines, free access in Belgium, funded by RIZIV-INAMI, translation in Dutch and French; adaptation to Belgian context ongoing
- More sources of guidelines are available on BIBKCE under Databases, Practice Guidelines or Practice Guideline, Publishers' catalogue
