Pay for Success/Health Impact Bonds

We are leading a demonstration project to evaluate pay-for-success/Health Impact Bonds to scale-up a proven asthma program in Fresno, CA (see http://ehp.niehs.nih.gov/121-a45/). Investors provide upfront capital to pay for the program, and health plans/insurers that benefit from reduced costs share validated savings with investors. Have other programs used similar kinds of financing?

Congratulations! That is fantastic. We'll leave this for others to chime in on this question.
