Similar to the RAND approach, each segment will be an "indication," which classifies population in terms of their needs in deciding which services to recommend, and these indications will be grouped for ease of evaluation into "chapters." The research team will identify potential experts from a distribution of relevant disciplines (4 doctors, 4 nurses/allied health professions, and 1 policy maker) in Singapore for the modified-Delphi study. They will be contacted personally to establish their interest to participate in this study, and the process will continue until the required number of panelists in the prescribed distribution are met. Panelists will be provided with a brief description of the method and how it will be applied to this study. The study will consist of an independent round of rating and a group meeting to reconcile the results.
