Traumatic Acute Subdural Hematoma

- Methods

A comprehensive online search for guidelines and articles was undertaken to identify the most relevant articles to be reviewed and guidelines to consider for adaptation.

Inclusion/exclusion criteria followed in the search were:

-  Selecting only national and/or international guidelines.

- Specific range of dates for publication (using guidelines published or updated 2015 and later)

-  A large series of case studies using surgical or nonsurgical management have been reviewed.

-  Selecting peer reviewed publications only.

-  Selecting guidelines written in English language.

- Selected articles were evaluated for design, prognostic significance, therapeutic efficacy, and overall outcome.

-  Case series on cases less than 10 in the study were excluded.

- Excluding guidelines written by a single author, not on behalf of an organization to be valid and comprehensive, a guideline ideally requires multidisciplinary input

-  Excluding guidelines published without references

-  The following characteristics were summarized in a table:

- Developing organization/authors

-  Date of publication, posting, and release

-  Country/language of publication

- Date of posting and/or release

-  Dates of the search used by the source guideline developers

All retrieved Guidelines were screened and appraised using the AGREE II instrument (www.agreetrust.org) by at least two members. The panel decided on a cut-off point or ranked the guidelines (any guideline scoring above 50% on the rigor dimension was retained). We choose for adaptation:
