Search Methodology

To access the full published Living Concussion Guidelines protocol, click on the following link: Protocol for a living systematic review for the management of concussion in adults 

In brief, a systematic review is being conducted to provide supporting evidence. Searches will be conducted at minimum every 6 months using the following databases: MEDLINE ALL, EMBASE, Cochrane, PsycInfo and CINAHL. So far, building on the Guideline for Concussion/Mild Traumatic Brain Injury and Persistent Symptoms: 3rd Edition, we have searched for literature published from May 2017 to the end of October 2022. 

The full search strategy for the MEDLINE ALL database is provided below as an example:
