Pubrica's scientific editing services use a "three-tier" editor procedure. First, a SME reviews the document for consistency, coherency, and intelligibility; second, another SME goes through the material again to recast ambiguous writing. Finally, the document was approved by the quality assurance team.

3. Delphi Study methodology
The Delphi approach is a systematic forecasting method that
relies on the collective knowledge of panel members.
The Delphi process for developing agreements among panel
members has gained favour in various medical sectors.
In recent decades, Delphi methodologies have played a crucial
role in developing best practice guidelines utilizing collective
intelligence when research is inadequate, ethically/logistically
challenging, or contradictory data .

4. However, attempts to analyze the quality standard of Delphi studies have revealed substantial variation,
and the specifics of the method are frequently obscure.
The following systematic quality tools are recommended for evaluating Delphi methodology: identification
of research problem area, panel selection, the anonymity of pane l lists , controlled feedback, iterative
Delphi rounds, consensus criteria, analysis of consensus, closing criteria, and stability of results.
Investigators examined the quality of Delphi studies in the medical sector connected to coronavirus illness
2019 using these 9 qualitative assessment parameters.
In addition, there was variation in reporting critical Delphi techniques, such as panel member identity,
consensus definition, round closing criteria, and outcomes presentation. In addition, our specialists at
Pubrica recommend assessment criteria for researchers , medical journal editorial boards, and reviewers
to assess the quality of Delphi techniques in healthcare research.

5. Problem area
The Delphi study is helpful when statistical model-based
evidence is unavailable, information is ambiguous and
inadequate, and human expert judgment outperforms
individual opinion.
Emerging diseases or disorders in healthcare frequently
mimic such domains, where typical research paths
cannot be implemented or have proven unfeasible.

6. These issue areas can be identified using a variety of ways, including
To reach a consensus, identifying issue areas and communicating with all
participating panel members should be explicit and completed before the final
survey rounds.
(1) an extensive systematic literature search;
(2) group discussion within a specified steering committee; and
(3) open-ended discussion rounds among panel members.
Panellists are members who take part in the Delphi survey's anonymous voting
procedure.
Panel members
contd..

7. The selection of panel members is, without a doubt, the most crucial part
of Delphi's research projects.
The methodology for identifying and selecting panel members differs in
published Delphi investigations. However, there are no standard criteria
for defining panel members.
Therefore, while evaluating the Delphi research, readers should keep the
following points in mind: Panel homogeneity, labelling panel members as
"experts," and panel size (1).

8. In healthcare research, there are no established quality measures for evaluating Delphi
techniques.
Anonymity, iteration, controlled feedback, and statistical stability of consensus are critical
components of the Delphi technique.
The published research employed a modified Delphi technique, and no specifics on procedures
such as expert panel, consensus, or closure criteria are provided. In addition, Pubrica
recommends methods for readers and researchers to use in conducting a systematic
assessment of the quality of Delphi studies.
