a) Most important for law is the area of epidemiology – the study of the occurrence of disease in a population. Addressed through statistics and is population based.
(1) Incidence: the number of new cases in a given population in a particular period of time. Incidence of anthrax is being calculated.
(2) Prevalence: the number of cases which exist in a population at this present time. Today, we might have 100,000 with head injuries.
(3) Most legal activity looks at the impact of the environment on the individual. EX: asbestos. Look at the number of cancers caused by that environment and compare to the number of cancers that would occur if not in that environment.
b) Clinical Study: looks at the accumulation of disease in individuals. Can be descriptive (based on height, weight, etc) and sociological (how a culture is quantified scientifically)
c) Clinical Trials: basis for understanding individual’s response to intervention in health care matters. Find a new drug or find a cure for a particular disease. Intervention includes surgical procedures, drugs, devices, etc.
