The present paper assesses health care services delivered in ambulatories and hospitals in the municipalities of the state of Rio de Janeiro, Brazil. The assessment is based on the use of non-stochastic frontiers models (data envelopment analysis - DEA) combined with regression techniques. By taking advantage of resources and production data, optimal levels of consumption and services are obtained. The paper shows relationships related to technical efficiency, GDP, population size and average length-of-stay.
