Measurement of hospital efficiency, using a latent class stochastic frontier model

This article analyses the technical efficiency of Portuguese hospitals from 1997 to 2008 with the latent class frontier model, enabling the identification of different segments in the cost frontier. It is found that there are three statistically significant segments in the sample, leading to the conclusion that no common health policy can be applicable to all the hospitals analysed, calling rather for policies conceived for each hospital segment identified. The health policy based in the identified segments enables a more accurate and cost effective management of resources.
