25. Changing world: Personalized Medicine@ USA
āThe term "personalized
medicine" is often described as
providing "the right patient with
the right drug at the right dose at
the right time."
More broadly, "personalized
medicine" may be thought of as
the tailoring of medical treatment
to the individual characteristics,
needs, and preferences of a
patient during all stages of care,
including prevention, diagnosis,
treatment, and follow-up.ā
