To achieve maximum health gain, many resources must come together at the same time: human, physical, and intellectual. The challenge of combining these inputs is becoming increasingly complex with the development of new diagnostics and treatments.

Moreover, ideological differences can complicate relations between different levels of the health care system, between the public and private sectors, and between vertical and horizontal programs.
