Do prevention or treatment services save money? The wrong debate.

Health improvements and cost savings are achievable by providing targeted, evidence-based, and cost-effective health promotion and disease prevention programs that reduce modifiable risk factors, often the cause of costly chronic diseases. Adopting commonsense health practices does not require expensive technology, medication, specialty training, or elaborate treatment facilities. Instituting environmental, policy, and normative interventions, in addition to individual behavior change programs, can shift our thinking about how we pay for health. Employers' efforts in providing health promotion programs to their workers offer a microcosm of how prevention can lead to populationwide risk reduction and cost savings.
