Document Summary
Risk: measure of the occurrence of new cases of disease of interest in a population. The probability of obtaining an outcome, given the presence or change in status of an exposure. Week 3 morbidity and mortality and morbidity rates. Example: in 1022 cancer patients with fever and granulocytopenia, 530 patients developed clinically or microbiologically documented bacterial infections. Mortality: rate of death due to a disease. Morbidity: rate of presence of a disease in a population. Incidence: rate of new cases (cumulative incidence, incidence density) Cumulative incidence: follow a single population to see how many new cases occur. Incidence density: follow a series of individuals at different times and for different durations (takes into account varying periods of time each participant was followed) Cumulative incidence = 2 cases/5 individuals/5 year period. = 8 per 100 over a 1 year period. Over a two year period, 28 people develop dumb-ass disease.
