Approval and permission for the study were requested from the MoH health research unit. Due care was taken to ensure that all those who agreed to participate in the study did so voluntarily, and gave their written informed consent. To this end, the researchers explained the aims and objectives of the study to all those involved and they were given an opportunity to ask for any clarification. Participants were informed that any information collected was to be kept confidential and that no names would appear on research documents, only identity (ID) numbers.
