Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA)

The AORN Guidelines for Perioperative Practice are a collection of evidence-based clinical practice recommendations that are developed based on a systematic review of the available literature. The methods used to develop clinical practice guidelines are important, with trustworthy methods resulting in trustworthy guidelines. The Preferred Reporting Items for Systematic reviews and Meta-analysis (PRISMA) statement and checklist is used by the authors of each AORN Guideline. The PRISMA statement and checklist, first published in 2009, has been used for each guideline developed or revised through December 2021. Beginning in January 2022, PRISMA 2020 is used for the development and revision of all AORN Guidelines. Changes to the content and structure of PRISMA 2020 reflect recent advancements in systematic review methodology and terminology and are intended to lead to more transparent, complete, and accurate reporting of systematic reviews, including those systematic reviews upon which AORN Guidelines are built. In the PRISMA 2020 flow diagram, references that are retained from the guideline being revised are listed in a distinct location, as are those references that were found in the current literature search and are distinguished from references that were added after the search. Information about the search terms, PRISMA flow diagram, and full search strategy for each guideline can be found in the Evidence Review document in the drop-down menu alongside the Evidence Table for that guideline.
