OBJECTIVE The aim of this study was to estimate the costs of implementing computerized physician order entry (CPOE) systems in hospitals in a rural state and to evaluate the financial implications of statewide CPOE implementation. METHODS A simulation model was constructed using estimates of initial and ongoing CPOE costs mapped onto all general hospitals in Iowa by bed quantity and current c...

in order to implement vat, various countries have applied different procedures including: manufacturing products, whole sale and consumer price procedures, according to their economic structure. for iran, it is proposed that in the first step, vat be confined to manufacturing products and imports, and after some successful implementation in this earlier step, with achieved experience and knowle...

Accidents at work are still a heavy burden in social and economic terms, and action to improve health and safety standards at work offers great potential gains not only to employers, but also to individuals and society as a whole. However, companies often are not interested to measure the costs of accidents even if cost information may facilitate preventive occupational health and safety manage...

one of the fundamental issues in the ethics of medical researches is cost-benefit assessment which consists a main part of related codes. this article is aimed to propose a model for ethical assessment of researches with judgment about their costs and benefits. after reviewing related materials and our experiences and discussions with experts, we proposed a model for ethical assessment of costs...

Considering the high costs of the implementation and maintenance of gas distribution networks in urban areas, optimal design of such networks is vital. Today, urban gas networks are implemented within a tree structure. These networks receive gas from City Gate Stations (CGS) and deliver it to the consumers. This study presents a comprehensive model based on Mixed Integer Nonlinear Programming (...

A~-This paper compares two implementation models for abstract data types: direct and indirect implementations. Direct implementations offer relatively cheap execution and expensive compilation costs while indirect implementations result in relatively expensive implementations and cheap compilation costs. These two models are both accommodated by Ada, and a small experiment compares their costs ...
