pathophysiology
a disorder of structure or function
disease
what sets the disease process in motion. The cause.
etiology
the manner of development of a disease
pathogenesis
fundamental structure of cells or tissues
morphology
defects present at birth, which may not become evident until later in life
congenital defects
study and analysis of the distribution and determinants of health and disease conditions in defined populations
epidemiology
number of new cases arising in a population during a specified time
incidence
number of people in a population who have a disease at a given time
prevalence
number of deaths in a given area or period of time from a specific cause
mortality
the effects an illness has on a persons life
morbidity
Keeping disease from occurring by removing all risk factors
primary prevention
Early disease detection; thereby increasing opportunities for intervention
secondary prevention
educes negative impact of an already established disease
tertiary prevention
The consistency or repeatability of a measure
test reliability
The extent to which a concept or measure corresponds accurately to the real world
test validity
The proportion of true positives that are correctly identified
test sensitivty
The proportion of true negatives that are correctly identified
test specificity
The probability that subjects with a positive test truly have the disease
positive predictive value (PPV)
The probability that subjects with a negative test truly do not have the disease
negative predictive value (NPV)
(T/F) the higher the test specificity, the lower the test sensitivity
True
difference between a sign and a symptom
a sign is objective evidence of a disease
a symptom is subjective evidence of a disease
what is Sx
