1. Calculating the Return on Investment of Mobile Healthcare The R.O.I. Algorithm

2. Basic Algorithm* E.R. Cost Avoided + Value of Quality Life Years Saved Cost of Mobile Health Clinic R.O.I. ($1,719,295 + $18,219,022) / $565,700 = $35 * All data based on 2008 Family Van Data and values as calculated in accompanying Algorithm worksheet

3. E.R. Cost Avoided cost of preventable E.R. visit (A) minus cost per visit of mobile health clinic (B) number of mobile health visits that prevent an E.R. visit (E) E.R. cost avoided (F) (A - B) * E = F (923 - 117) * 2,133 = $1,719,295

4. Calculating Avoidable E.R. Visits Total Visits Percentage of visits expected to otherwise have resulted in an E.R. visit * number of mobile health visits that prevent an E.R. visit (E) 4,848 * 44% = 2,133 * Cunningham, Peter J.: HealthAffairs25(2006): w324–w336; 10.1377/hlthaff.25.w324

5. Value of Quality Life Years Saved Number of Quality Adjusted Life Years saved (QALYs) Value of a Statistical Life Year (VSLY) Relative Value of Quality Adjusted Life Years Saved 260 * $70,000 = $18,219,022
