As we discuss the whole question of the NHI system, I think those are the case studies that we need to look at in regard to whether they will assist to achieve the objectives of the NHI. We also recall that in the Green Paper that has been released for public comment, the NHI also indicates that the service providers will be accredited. So, if those are the models that are in line with the objectives of affordability, efficiency and effectiveness in regard to the health of the population in that area, they will be assessed accordingly and, if found appropriate, they will be accredited. So, indeed, the health system is integrated and the ministry is committed to working with all South Africans in that regard.
