Your program’s Bottom Line Impact is the combination of system impact calculations as well as program impact calculations. In other words, it is the combination of costs saved from avoided emergency room visits and the number of quality-adjusted life years that were determined from the types of preventative services provided by the mobile clinic. Bottom Line Impact = System Impact + Program Impact The return on investment portion of the bottom line impact display shows the ratio between the total cost savings provided by the mobile clinic and the total cost of running the clinic. Return on investment = (System Impact + Program Impact) / (Total Program Costs) A high return on investment shows that your program provides a high value to the surrounding community in relation to the level of investment in your clinic.
