"A set of recommendations defining conditions for using or not using available interventions in clinical or public health practice. Practice guidelines may be evidence-based and referred to as evidence-based guidelines or evidence-based recommendations." (Riegelman, R.K. (2005). Studying a study & testing a test: How to read the medical evidence. Philadelphia: Lippincott Williams & Wilkins.)
In other words, practice guidelines are sets of evidence-based, systematically developed recommendations for health care.
The following resources provide access to practice guidelines, which are based on the latest evidence. Many practice guidelines include ratings of the level of evidence for each recommendation for prevention or treatment. Level of evidence is based on the type of study that supports the recommendation, from case reports and editorials on the low end up to systematic reviews on the high end. For more information on levels of evidence, please refer to the Types of Studies guide.
Searches in PubMed can be limited to display only Practice Guidelines. Access PubMed@Himmelfarb. After performing a search in PubMed, under MY NCBI FILTERS, select "Practice Guidelines". You should now see that your results list is much shorter and restricted to Practice Guidelines only.
Searches in Ovid MEDLINE can also be limited to display only Practice Guidelines. On the main search screen under Limits, scroll to "Practice Guidelines" in the Publication Types. Select this from the list and then proceed with your search.
