Introduction — This topic includes links to society and government-sponsored guidelines from selected countries and regions around the world. We will update these links periodically; newer versions of some guidelines may be available on each society's website. Some societies may require users to log in to access their guidelines.

The recommendations in the following guidelines may vary from those that appear in UpToDate topic reviews. Readers who are looking for UpToDate topic reviews should use the UpToDate search box to find the relevant content. Links to related guidelines are provided separately.
