It’s oen useful to ask questions about programs without actually running them. For example, we might want to know if a program contains some class of bugs such as division by zero or memory access errors. For compilers static information is vital for good quality machine code generation. Another class of questions is about cost of running a program. For instance, we might want to know if the p...

CEA is a tool that has seen increasing use in recent decades as decision makers at all levels of health care provision seek to value alternative interventions (or programs, tests, or treatments). Although CEAs can be complex, and are often described using somewhat arcane terminology, the concept at the core of any CEA is fairly simple: to combine the net cost of a given intervention and its out...

Cost-effectiveness analysis refers to the consideration Of decision alternatives in which both their costs and consequences are taken into account in a systematic way. It is a decisionoriented tool, in that it is designed to ascertain which means of attaining particular educational goals are most efficient. For example, there are many alternative approaches for pursuing such goals as raising re...

The purpose of this study was to evaluate and compare the clinical effects, safety, and economic cost of propofol and midazolam in the sedation of patients undergoing mechanionl ventilation in the ICU. Eighty-eight critically ill patients were studied and randomly allocated to receive short-term (less than 24 h), medium-term (24 h to 7 days), and prolonged (more than 7 days)continuous sedation ...

The demand for home health care has skyrocketed in recent years. The aging population and the push for more efficient delivery of hospital services have fueled this growing demand. However, health care financing reforms have constrained the industry's growth. Home health agencies struggle to deliver high-quality services while staying within the financial limitations imposed by reimbursement ch...

When different health care interventions are not expected to produce the same outcomes both the costs and the consequences of the options need to be assessed. This can be done by cost-effectiveness analysis, whereby the costs are compared with outcomes measured in natural units--for example, per life saved, per life year gained, and per pain or symptom free day. Many cost-effective analyses rel...

Order is the key word of science. Scientists have tried to order and explain all the phenomena of the universe. They found that the planets and stars move along predictable paths, discovered the laws of gravitation and devised formulae to describe inheritance. For them, the universe is like a clock. Their mission is to discover and explain the mechanism of this clock and thus explain the laws t...
