Architectural modeling and analysis are mechanisms that allow the capture of design decisions early in the process, so that they can be assessed and modified without incurring the costs of incorrect implementations.
If this cost analysis was broadened to include the cost implications of incorrect diagnoses incurred at both the household and health system level the likelihood is that RDTs would be cost-effective from the societal perspective even if the unit cost of an RDT was to increase beyond the thresholds identified here.
A key characteristic of this approach is that, given complete knowledge of the statistics of the patterns to be classified, the Bayes rule defines the optimum classifier that minimizes the probability of classification error or the expected cost of an incorrect decision [ 17].
However, care should be taken as this makes the implicit assumption that the costs of all incorrect decisions are equal.
In practice, a precise determination of the costs and benefits of incorrect and correct classifications may be rather difficult.
This value illustrates the opportunity cost of making the incorrect decision, calculated as the difference between the expected net benefit with perfect information and the expected net benefit with current information.
Neither the financial nor economic estimates of cost are incorrect, but the difference indicates that the healthcare sector is an imperfect economic system (15 ).
In determining costs for incorrect decisions, we have presumed standard clinical treatment of abnormal beats, or non-treatment of normal beats according to the system's output.
P..d off we had a ref who cost us Crewe game cause of incorrect decision was given us again, then sent manager off & many yellows today!
"...that we had a ref who cost us Crewe game because of incorrect decision was given us again, then sent manager off and many yellows today!" "... that as going has got tough many thousands of fans have bit like our players, have folded and taken their ball and gone home!" "...Tomorrow I'll still pay the bills & next Saturday will pay thousands to watch my team play & hopefully win".
