Data collection tools produced and used as part of a Delphi consensus study to co-develop a comprehensive disease policy model for Malaria prevention during pregnancy. The Delphi technique was used to build consensus on the opinion of panel members, through a series of structured questionnaires administered in an iterative multi-round process. In each round, experts were sent a draft model and asked to complete an online survey, in which they reviewed and rated possible outcomes, associations/relationships, costs and other factors shown in the model draft. Data was collected from 12 experts in the field of malaria during pregnancy over two rounds of Delphi consultations using web-based questionnaires.
