Demonstration of Interactive Multivariate Calculator

The development of a  paper by Michael Glinski about Spurious Hypocalcemia associated with the use of MRI contrast agents revolved around analysis of the clinical and economic impact. The cost impact is affected by many variables. An interactive tool was developed so that health care professionals could rapidly and accurately examine many scenarios that reflected various assumptions about prevalence and cost.

Each new position of the sliders represents the complete re-calculation of a spreadsheet based on the changes to one variable. 

It is a little like a mortgage calculator, but much more advanced. If you lower interest rate and increase the term of the financing, the payment changes. Conversely, if you decrease the payment, you can see the new length of the loan or  financed amount.  

The interactive tool is shown below. Use your mouse to drag the sliders, exploring the variables and seeing the results in real time. Notice also that in part two, the Rate and Unit Cost are also variables that can be adjusted for a specific situation.  Also helpful is the ability to store a record of Scenarios.

Tools such as this can be developed by oag for a variety of custom situations to suit your needs.
