Medical Insurance $$'S for Retrofits

This is a novel idea:
               What if the dollars spent on asthma and other respiratory/sinus issues are directed at residential indoor air quality? Imagine an asthmatic child who is an emergency room super-utilizer getting a prescription for a home performance retrofit from her doctor and her insurance provider paying for it. A typical day at the ER is around $1250. An asthmatic child will trigger once a month in the "right" conditions. That's $15000 in health care that does not help the child since she goes home to the same unhealthy environment. Let's spend that $15K on a whole house retrofit and remove the asthma triggers from her home.
                This is proactive, preventative and long lasting health care that positively affects the whole family by reducing sick school days and missed income from medically related loss of work, not to mention overall improvement in productivity and quality of life. Oh, and by the way, reduced energy costs. ;-)
