Strengths and limitations of the study
Delphi technique in this survey is not bound by geographical locations
of the participants and offers flexible opportunities for them to share
their opinions and minimising bias of dominant experts(17, 42). The process is anonymous and hence has the
advantage of minimising challenges of the hierarchical culture that we
would anticipate among Indonesian health care professionals(43-45).
Although sample size in this study was small, the recruitment of
participants with various backgrounds and experiences have captured
broad views and opinions from the experts (46). The
survey has also optimised the participants interaction by providing them
opportunities to view and revise their responses at the previous rounds.
Result validity of the study is justified by the high survey
participation rates in each round and the high percentages of agreed
statements completed with good agreement scores (17,
47).
