Demand-oriented and demand-driven health care: the development of a typology.

In most European countries, there is an increasing demand for demand-oriented and demand-driven approaches in the development of health care policy and the organization of health care services. Both approaches, in which the main focus is on 'the demand', are seen as counterparts of the supply-oriented approach, that has 'the supply' as point of departure. However, there is much confusion about the definition of the concepts. To identify the different views, and to examine to what extent there is consensus in the Netherlands about the concepts of demand-orientation and demand-driven care, a Delphi study was done among 26 experts; scientists, health care insurance companies, health care suppliers, the government, independent advisory bodies and client interest groups. The study resulted in a typology. The similarities and differences between the two concepts were demonstrated in five dimensions; responsibility, control, need-determination, formal embedment of vision in organization and choice. Furthermore, the typology was used to identify existing types of services as being either demand-oriented or demand-driven services. The typology provides an understanding of the similarities and differences between the two concepts, and appears to be a useful tool in identifying services to the extent that they are demand oriented or demand driven.
