Epidemiology for the Advanced Practice Nurse: A Population Health Approach


Epidemiologic investigations provide evidence regarding the linkage between an exposure and the occurrence of a disease or health condition. This epidemiologic investigation also provides evidence as to the magnitude of risk associated with the exposure as compared to the extent to which the exposure’s relationship to the disease or health condition occurred by chance alone. Risk can be defined as the probability or likelihood that an adverse health event will occur in an individual or population. This chapter describes the steps of a risk assessment. It helps the reader calculate relative risk, odds ratio, and attributable risk. Nurses, as healthcare providers, educate patients on the risk associated with lifestyle behaviors and exposures to various disease-causing agents. During the nursing assessment, various types of risks can be further investigated and explored to determine an individual level risk profile.
