Measuring routine nursing service efficiency: a comparison of cost per patient day and data envelopment analysis models.

Abstract: This article provides an illustrative application of Data Envelopment Analysis (DEA) methodology to the measurement of routine nursing service efficiency at a group of Wisconsin hospitals. The DEA efficiency ratings and cost savings estimates are then compared to those resulting from application of Medicare's routine cost limitation to the sample data. DEA is also used to determine if any changes in the potential for efficient operations occurred during the 1978-1979 period. Empirical results were representative of the fundamental differences existing between the DEA and cost per patient day approaches. No evidence was found to support the notion that the overall potential for efficient delivery of routine services by the sample institutions was greater in one year than another.

Evaluation of Educational Program Proposals by Means of DEA

Abstract: A new application of DEA (Data Envelopment Analysis) is examined for evaluating the efficiency of occupational-technicalprograms in a comprehensive community college. This includes extensions of DEA for use in evaluating new programs that might be introduced along with possible combinations of old programs. Emphasis is placed on the relative efficiency aspects of DEA so that consequences for the efficiency ofprograms other than those being considered can be taken into account. Uses by the director of San Antonio College are described and placed in a context of the other elements that entered into her decisions. In conclusion, possible further improvements in DEA are discussed along with the kinds of research needed to achieve them.

Data Envelopment Analysis and Extensions for Decision Support and Management Planning.

Abstract: : The public expects military efficiency from the combat forces it supports with tax dollars. The United States Air Force needs integrative measures of efficiency and needs decision support systems which aid in detecting inefficiencies, diagnosing problems, and choosing among alternative courses of action to improve the efficiency and effectiveness of combat units. The Data Envelopment Analysis (DEA) technique developed by Charnes, Cooper and Rhodes provided the basic theoretical starting point for this dissertation. It anables the unified analysis of multiple technical, economic and effectiveness measures in contrast to past reliance by Air Force Management on 'partial' measures of productivity, cost effectiveness, etc. Theory was extended by this study to provide analytical capabilities suitable for use by the Air Force in the analysis and interpretation of efficiency and in the preparation of management plans. This dissertation provided a basic theoretical framework for future development of decision support prototypes suitable for use by the Air Force in managing military effectiveness and efficiency.

Pareto-Optimality, Efficiency Analysis and Empirical Production Functions.

Abstract: : The construction and analysis of Pareto-optimal frontier production functions by a new Data Envelopment Analysis method is developed in the context of new theoretical characterizations of the inherent structure and capabilities of such empirical production functions. Contrasts and connections with other developments, including solutions of some remaining problems, are made re aspects such as informatics, economies of scale, isotonicity and non-concavity, discretionary and nondiscretionary inputs, piecewise linearity, partial derivatives and Cobb-Douglas properties of the functions. Non-Archimedean constructs are not required. (Author)
