In this paper we analyze the effects of some distortions induced by the prospective payment system, i.e. upcoding, cream skimming and readmissions, on hospitals' technical efficiency. We estimate a production function using a population-based dataset composed by all active hospitals in an Italian region during the period 1998-2007. We show that cream skimming and upcoding have a negative impact on hospitals' technical efficiency, while readmissions have a positive effect. Moreover, the results indicate that private hospitals engage more in cream skimming than public and not-for-profit ones, while we observe no ownership differences regarding upcoding. Not-for-profit hospitals have the highest readmission index. Last, not-for-profit and public hospitals have the same efficiency levels, while private hospitals have the lowest technical efficiency. © 2009 Elsevier B.V.

Abstract
In this paper we analyze the effects of some distortions induced by the prospective payment system, i.e. upcoding, cream skimming and readmissions, on hospitals' technical efficiency. We estimate a production function using a population-based dataset composed by all active hospitals in an Italian region during the period 1998-2007. We show that cream skimming and upcoding have a negative impact on hospitals' technical efficiency, while readmissions have a positive effect. Moreover, the results indicate that private hospitals engage more in cream skimming than public and not-for-profit ones, while we observe no ownership differences regarding upcoding. Not-for-profit hospitals have the highest readmission index. Last, not-for-profit and public hospitals have the same efficiency levels, while private hospitals have the lowest technical efficiency. © 2009 Elsevier B.V.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
