There has been increasing interest in the ability of different methods to rank efficient hospitals over their inefficient counterparts. The UK Department of Health has used three cost indices to benchmark NHS Trusts. This study uses the same dataset adn compares the efficiency rankings from the cost indices with those obtained using Data Envelopment Analysis (DEA) and Stochastic Cost Frontier Analysis (SCF). The paper concludes that each method has particular strenghs and weaknesses and potentially measure different aspects of efficiency. Several specifications should be used to develop ranges of inefficiency to act as signalling devices rather than point estimates. There appears to be a large amount of random "noise" in the study which suggests that there are not truly large efficiency differences between Trusts, and savings from bringing up poorer performers would in fact be very modest.
