Empirical results also showed that the hospitals under study were operating at respectable levels of scale efficiency from 85.9% up to 94.6%. Detailed results, summarized in Table 3, show that a small number of hospitals were operating at optimal size (characterized by constant returns to scale), though many others were operating close to their optimal size. Furthermore, by examining individual scale efficiency findings, it was concluded that the hospitals under study exhibit a mix of decreasing and increasing returns to scale at current levels of output. Interestingly, the pattern of scale inefficiency indicates that most of the hospitals are operating in an area of increasing returns to scale implying that they could benefit from increasing the scale of their operations. At this point two things need also to be taken into account. First, the size of each hospital should be interpreted relatively in the context of the group it belongs to and therefore it should not be seen as an absolute “big” or “small” number. Second, scale inefficiency for many hospitals account for as little as 5% or even less. This implies that the potential for their improvement through resizing is rather limited. These findings suggest that hospital managers and policy makers should primarily focus on addressing the technical inefficiency issues before examining ways for a possible restructure of their scale of operations. Besides, it should not be overlooked that technical improvement is more controllable and can be addressed in the short-term without requiring the prior change of scale.
