the Management of Adrenal Lesions
- Methods
A comprehensive search for guidelines was
undertaken to identify the 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 within the last five 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 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:
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 AGREE II instrument (www.agreetrust.org) by at least three members. The panel
decided on a cut-off point (any guideline scoring above 50% on the rigor dimension was retained). The GDG decided to adapt
the European Society of Endocrinology clinical practice guidelines on the
management of adrenal incidentalomas, in collaboration with the European
Network for the Study of Adrenal Tumors, 2023,(1).
Evidence assessment
According to WHO Handbook for Guidelines,
we used the GRADE (Grading of Recommendations, Assessment, Development and
Evaluation) approach to assess the quality of a body of evidence, develop
and report recommendations. GRADE methods are used by WHO because these represent
internationally agreed standards for
making transparent recommendations. Detailed GRADE information is available on
the following sites:
•
GRADE
working group: https://www.gradeworkinggroup.org/
•
GRADE
online training modules: http://cebgrade.mcmaster.ca/
Specifically, the quality of evidence was
graded as ‘High’, ‘Moderate’, ‘Low’ or ‘Very low’, (table 2& 3).
The strength of the
recommendation
The strength of a recommendation
communicates the importance of adherence to the recommendation.
Strong recommendations
With strong recommendations, the guideline
communicates the message that the desirable effects of adherence to the
recommendation outweigh the undesirable effects. This means that in most
situations the recommendation can be adopted as policy.
Conditional recommendations
These are made when there is greater
uncertainty about the four factors above or if local adaptation has to account
for a greater variety in values and preferences, or when resource use makes the intervention suitable for some, but
not for other locations. This means that there is a need for substantial debate
and involvement of stakeholders before this recommendation can be adopted as
policy.
When not to make recommendations
When there is lack of evidence on the
effectiveness of an intervention, it may be appropriate not to make a recommendation.
