Summary | Frontier techniques have been used to measure healthcare provider efficiency in hundreds of published studies. Although these methods have the potential to be useful to decision makers, their utility is limited by both methodological questions concerning their application. The aim of this paper is to examine the data envelopment analysis (DEA) and stochastic frontier analysis (SFA) results in order to facilitate a common understanding about the adequacy of these methods, defining any differences in healthcare efficiency estimation. A two-stage bootstrap DEA method and the formula of the SFATranslog were performed. Multi-inputs and multi-outputs were used in both of the approaches assuming two scenarios either including environmental variables or not. One hundred twenty (120) Greek public hospital units constitute the sample with a panel data period 2009-2011. DEA and SFATranslog were found to yield different efficiency estimates due to the nature of the environmental variables and statistical noise. Most of the environmental variables were found significantly correlating with inefficiency. There is a need for careful attention by stakeholders to be specific when choosing the appropriate mathematical form since the nature of the data and its availability influence the measurement of the efficiency. | |
