Epidemiology - is the science of public health Population Health - focuses on risk, data, demographics, and outcomes. Outcomes - is the end result that follows an intervention aggregate - is a defined population. community - is composed of multiple aggregates data - is complied information Prevalence - measures the existence of a disease. Measures the number of all cases of a disease or attribute in a population at a given time Incidence - measures the appearance of a disease. Measures the occurrence of new events in a population over a period of time. surveillance - is the collection, analysis, and dissemination of data. high-risk - is an increased chance of poor health outcome. Morbidity - is the presence of illness in a population mortality - is related to the tracking deaths in an aggregate vital statistics - statistics on live births, deaths, fetal deaths, marriages and divorces. cases - set of criteria used in making a decision as to whether an individual has a disease or health event of interest Social Justice - the view that everyone deserves equal rights and opportunities — this includes the right to good health Inter-professional collaboration - The idea of sharing and implies collective action oriented toward a common goal, in this case, improving the quality and safety ofpatient care.

Determinants of care/health - The range of personal, social, economic, and environmental factors that influence health status are known ... risk analysis - the characterization of the potential adverse health effects of human exposures to environmental hazards health disparities - the difference in health statuses between various groups (populations). Sensitivity - measures the proportion of actual positives that are correctly identified as such (e.g., the percentage of sick people who are correctly identified as having the condition) Specificity - (also called the true negative rate) measures the proportion of actual negatives that are correctly identified as such (e.g., the percentage of healthy people who are correctly identified as not having the condition) Positive predictive value - is the probability that subjects with a positive screening test truly have the disease epidemiological triangle - 1. A traditional model of infectious disease causation, known as the Epidemiologic Triad is depicted in Figure 2. The triad consists of an external agent, a host and an environment in which host and agent are brought together, causing the disease to occur in the host.
