“Of the $5000 per employee the average employer spent on health care in 2001, more than 95% was spent on diagnosis and treatment, with maybe 2-3% being invested in early detection (screenings) and no more than 1-2% in prevention. This reactive approach persists despite evidence that up to 50% of health care expenditures are life-style related and therefore potentially preventable.”
