Adjusted for differences in purchasing power and practice expenses, Canadian physician fees are, on average, 59 percent of Medicare fees. The general perception that Medicare fees are low is the result of comparison with U.S. private fees, not to the much lower Canadian fees. In the context of the current U.S. health care system, lowering Medicare fees to Canadian levels could jeopardize access...

Using the Diagnostic Cost Group (DCG) model developed from a national sample, we examine biased selection among one fee-for-service (FFS) plan, one preferred provider organization, and several health maintenance organizations (HMOs) in Massachusetts. The proportions of enrollees in low-risk groups are higher in the HMO plans and lower in the FFS plan. The average age in the FFS plan is 9 years ...

Data envelopment analysis (DEA) is a technique that takes account of multiple inputs and outputs to assess the relative efficiency of organisational units. Unlike regression its assessments are not based on any average but on best observed practice (and weighted combinations thereof). Whilst DEA has seen an explosive growth in its application to various fields, it has rarely been applied to the...

This paper deals with the new method of solving the problem of data set allocation optimization problem in the distributed database systems. The method is based on the combined use of object model of the distributed database and modified genetic algorithm. The criterion for optimum is defined by the minimum total average time required to process queries and disseminate updates. The experimental...

BACKGROUND/PURPOSE Infectious disease physicians (IDPs) play a major role in patient care, infectious disease control, and antibiotic use in hospitals. The aim of this research is to explore the effects of employment of IDPs on patients' prognosis and the related medical and antibiotic expenses in hospitals. METHODS This population-based study provides evidence-based information on IDPs' cont...

The increasing usage of sensor-actuator networks by NCS/SCADA systems raises significant concerns about privacy. Developing novel schemes for demand response in smart electric gird is an increasingly active research area. These schemes aim to control/flatten demand curves and shift consumption times to the off-peak periods, which allows to to improve efficiency. Indeed, higher volatility of use...
