Health Economics:Does Preventive Care Save Money?

When it comes health care we should plan "focus on prevention: wellness not sickness", Many studies shows that primary and preventive care greatly reduces future health care costs, as well as increasing patients health.

Indeed, some evidence does suggest that there are opportunities to save money and improve health through prevention. Preventable causes of death, such as tobacco smoking, poor diet and physical inactivity, and misuse of alcohol have been estimated to be more deaths in our countries. Sweeping statements about the cost-saving potential of prevention, however, are overreaching. Studies have concluded that preventing illness can in some cases save money but in other cases can add to health care costs. For example, screening costs will exceed the savings from avoided treatment in cases in which only a very small fraction of the population would have become ill in the absence of preventive measures. Preventive measures that do not save money may or may not represent cost-effective care (i.e., good value for the resources expended). Whether any preventive measure saves money or is a reasonable investment despite adding to costs depends entirely on the particular intervention and the specific population in question. For example, drugs used to treat high cholesterol yield much greater value for the money if the targeted population is at high risk for coronary heart disease, and the efficiency of cancer screening can depend heavily on both the frequency of the screening and the level of cancer risk in the screened population.

The focus on prevention as a key source of cost savings in health care also sidesteps the question of whether such measures are generally more promising and efficient than the treatment of existing conditions. Researchers have found that although high-technology treatments for existing conditions can be expensive, such measures may, in certain circumstances, also represent an efficient use of resources. It is important to analyze the costs and benefits of specific interventions.

Findings that some cost-saving or highly efficient measures are underused would indicate that current practice is inconsistent with the efficient delivery of health care. Other services might be identified as overused, and such findings would underscore the importance of fashioning policies that provide incentives to shift practice toward more cost-effective delivery of health care. In the face of increasingly constrained resources, there is a realistic way of achieving better health results:

• conduct careful analysis to identify evidence-based opportunities for more efficient delivery of health care — whether prevention or treatment.

• Restructure the system to create incentives that encourage the appropriate delivery of efficient interventions.
