A comprehensive search for guidelines was undertaken to identify the most relevant guidelines to consider for
adaptation.
Inclusion/exclusion criteria followed in the search and retrieval of guidelines to be adapted:
· Selecting only evidence-based guidelines (guideline must include a report on systematic literature searches and explicit links between individual recommendations and their supporting evidence)
· Selecting only national and/or international guidelines
· Specific range of dates for publication (using Guidelines published or updated in the last 10 years)
· Selecting peer reviewed publications only
· Selecting guidelines written in English language
· Excluding guidelines written by a single author not on behalf of an organization in order to be valid and comprehensive, a guideline ideally requires multidisciplinary input
· Excluding guidelines published without references as the panel needs to know whether a thorough literature review was conducted and whether current evidence was used in the preparation of the recommendations.
The following characteristics of the retrieved guidelines were summarized in a table:
• Developing organization/authors
• Date of publication, posting, and release
• Country/language of publication
• Dates of the search used by the source guideline developers
All retrieved Guidelines were screened and appraised using AGREE II instrument (www.agreetrust.org) by at least two members. the panel decided a cut-off point or rank of the guidelines (any guideline scoring above 50% on the rigor dimension was retained). The GDG decided to adapt the ERC 202513, AHA 202520, ILCOR14, and CoSTR14 recommendations adapted to the local context.
