|Background To The ROI Widget|
IMC’s ROI (Return on Investment) widget is designed to give users or potential users of electronic compliance monitoring (ECM) a feel for the return on investment. Although ECM comes at a cost, the return on investment typically dwarfs the initial outlay. Many factors, some of which are likely to be unknown, underlie any ROI calculation, and the ROI widget makes a number of assumptions. Thus, the results should be viewed as estimates, but the ROI calculation is based on conservative assumptions and should, in most cases, underestimate the true ROI. The ECM quantifies patient non-compliance, a source of noise, and reduces its contribution to the denominator of the S/N ratio. This allows the signal to stand out better. This is what generates the ROI.
