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).
