[Financing, organization, costs and services performance of the Argentinean health sub-systems.]

To analyze the relationship between health system financing and services organization models with costs and health services performance in each of Rosario's health sub-systems.

The financing and organization models were characterized using secondary data. Costs were calculated using the WHO/SHA methodology. Healthcare quality was measured by a household survey (n=822).

Public subsystem:Vertically integrated funding and primary healthcare as a leading strategy to provide services produced low costs and individual-oriented healthcare but with weak accessibility conditions and comprehensiveness. Private subsystem: Contractual integration and weak regulatory and coordination mechanisms produced effects opposed to those of the public sub-system. Social security: Contractual integration and strong regulatory and coordination mechanisms contributed to intermediate costs and overall high performance.

Each subsystem financing and services organization model had a strong and heterogeneous influence on costs and health services performance.
