Electronic medical record use and efficiency: A DEA and windows analysis of hospitals

We use data envelopment analysis (DEA) to examine the relationship between hospital electronic medical record (EMR) use and efficiency in a national sample of acute care hospitals. Data sources include the American Hospital Association (AHA), Health Information Management Systems Society (HIMSS), and Case Mix Index. Using two research approaches including a retrospective, cross-sectional design and a first differencing repeated measures design, we find limited evidence that EMRs can improve hospital efficiency. Small hospitals may benefit in the area of efficiency through EMR use, but medium and large hospitals generally do not demonstrate such a difference. Likewise, there does not appear to be a significant increase in efficiency over time associated with EMRs when compared to the efficiency of hospitals without such documentation.     

Using DEA to estimate potential savings at GP units at medical specialty level

The aim of this paper is to identify benchmark cost-efficient General Practitioner (GP) units at delivering health care in the Geriatric and General Medicine (GMG) specialty and estimate potential cost savings. The use of a single medical specialty makes it possible to reflect more accurately the medical condition of the List population of the Practice so as to contextualize its expenditure on care for patients. We use Data Envelopment Analysis (DEA) to estimate the potential for cost savings at GP units and to decompose these savings into those attributable to the reduction of resource use, to altering the mix of resources used and to those attributable to securing better resource ‘prices’. The results reveal a considerable potential for savings of varying composition across GP units.

Two-Stage DEA: An Application to Major League Baseball

We show how to use DEA to model DMUs that produce in two stages, with output from the first stage becoming input to the second stage. Our model allows for any orientation or scale assumption. We apply the model to Major League Baseball, demonstrating its advantages over a standard DEA model. Our model detects inefficiencies that standard DEA models miss, and it can allow for resource consumption that the standard DEA model counts towards inefficiency. Additionally, our model distinguishes inefficiency in the first stage from that in the second stage, allowing managers to target inefficient stages of the production process.     

New evidence on the efficiency of Italian airports: A bootstrapped DEA analysis

A bootstrapped DEA procedure is used to estimate technical efficiency of 18 Italian airports during the period 2000-2004. Departing from previous studies, we separate the efficiency related to ability to manage airside activities (operational) from that related to the management of all business activities (financial). In general, Italian airports operate at poor levels of efficiency, with slightly better performance in terms of their financial activities. In the current study, selected intrinsic and environmental characteristics are considered as possible drivers of Italian airport performance. In particular, we found that: (i) the airport dimension does not allows for operational efficiency advantages, (ii) on the other hand, the airport dimension allows for financial efficiency advantages for the case of hubs and disadvantages for the case of the smallest airports (iii) the type(s) of concession agreement(s) might be considered as important source of technical efficiency differentials for those airports running marginal commercial activities; (iv) the introduction of a dual-till price cap regulation might create incentives which lead to the increase of financial efficiency at the detriment of the operational performance. Lastly, the development of a second hub (Milano Malpensa), has negatively affected the performance of the country’s national hub (Roma Fiumicino).     

Finding Closest Targets in Non-Oriented DEA Models: The Case of Convex and Non-Convex Technologies

This paper draws attention for the fact that traditional Data Envelopment Analysis (DEA) models do not provide the closest possible targets (or peers) to inefficient units, and presents a procedure to obtain such targets.It focuses on non-oriented efficiency measures (which assume that production units are able to control, and thus change, inputs and outputs simultaneously) both measured in relation to a Free Disposal Hull (FDH) technology and in relation to a convex technology. The approaches developed for finding close targets are applied to a sample of Portuguese bank branches.

基于DEA模型的河南地区物流企业投入产出效率分析

建立评价物流投入产出的指标,基于DEA的C2R和C2GS2模型,分析研究了2012年河南地区17个城市的物流投入产出效率。结果表明,DEA总体无效的城市有10个,河南地区物流投入产出纯技术平均效率、纯规模平均效率以及总体平均效率分别是0.78、0.90、0.72。说明物流效率偏低的主要原因是纯技术效率偏低,并对DEA总体无效的城市提出了物流业发展建议。
