    Guideline Summaries (beta)

    Welcome to Guideline Summaries (beta)—interactive point-of-care summaries of clinical practice guidelines, many developed in collaboration with our society partners. Our summaries are extracted directly from practice guidelines to quickly provide the information you need at the bedside. Use them to stay current on evidence-based guideline recommendations.

    Each recommendation statement displays the strength of recommendation and level of evidence assigned by the society. You can find the legend below the guideline statements.
