A review and analysis of the clinical and cost-effectiveness studies of comprehensive health promotion and disease management programs at the worksite: update VI 2000-2004.

This critical review focuses on the 12 new studies focused on the clinical and cost outcomes research focused on worksites and published between 2000 and 2004. Although these new studies indicate further evidence of positive clinical and cost outcomes, the quantity and quality of such research continue to decline. When corporations and health plans are demanding more evidence-based outcomes, this decline in rigorous research marks a serious challenge to the field of health promotion and disease management.
