Parametric. Until recently, limited healthcare information was available to and about individuals and populations. A single parameter (such as blood pressure) was measured as the sole determinant of a disease (hypertension) and various regimes were instituted based upon the single parameter. Now there are many more diagnostic devices and tests that will be able to contribute to the final diagnosis of a disease, such that using multiple parameters it will be possible to more accurately classify diseases or discover onset of disease earlier than by using a single late-manifesting parameter. The paradigm will be come collecting multiple parameters over time, determining the change over time (which is more critical than isolated measurements), comparing that change to the person’s own baseline in the past, and interpreting these changes relative to a population standard for age, sex, race, etc. Information science permits us to now collect analyze and understand the complexity of the dynamic interactions of multiple parameters over time.
