The qualitative study used a number of focus group discussions and semi-structured interviews to gather data. The  guides to the processes are online here  for colleagues who may wish to view how we went about this study. Replication of these guides will require  contextual adaptation.  With the consent of respondents, all interviews and focus group discussions were recorded and transcribed, and we kept  detailed notes, all of which  were  essential  for an audit trail of our research. Thematic data  analysis  was done with the help of  AtlasTi.
