Having quantitative indices of overall health of citizens is essential to moving from ad hoc decisions to a systematic approach for public health maintenance, and for individual care. In recent months, for lack of an overall health indicator, policies for whom to vaccinate with the (Scarce) H1N1 flu vaccine in the United States has been made on a fairly ad hoc basis. Similarly, for someone who has a mild degree of a number of illnesses but whose overall health is poor because of comorbidity of different conditions needs to be aware of the severity of his condition. Hence, it is important that the health care system be more proactive about health management.
