Week 4 Midterm – NR503Chamberlain college of nursing latest edition 20241. Epidemiology is the study of the disease distribution within populations and the risk factors that affect increases or decreases in distribution. The science of epidemiology serves first to find out the “why” of disease and then analyze these factors for recommendations in disease screening, treatment, prevention, and monitoring. Understanding population disease helps enact proper screening, prevention, diagnostic, and therapeutic plans for patients. 2. Population Health is the health outcomes of a group of individuals – it aims to improve the health of an entire human population by addressing social, environmental, and medical determinants of health. Organizations work together in order to improve the health outcomes of the community they serve. (Public health works to protect and improve health of communities through policy recommendations, health education, and research for disease detection and injury prevention). 3. HP2020 objectives and goals- nat’l document with agreed-upon national objectives that guides and assists APNs to focus on and identify le3vels of population healthcare for persons across the life span. Goals are to attain high quality, longer lives free of preventable disease, disability, injury and premature death; achieve health equity, eliminate disparities, and improve the health of all groups. 4. Understand and compare the different measures – Morbidity is another term for illness. Prevalence is a measure often used to determine the level of morbidity in a population. Morbidity is NOT death. Prevalence is a measure of disease that allows us to determine a person’s likelihood of having a disease. The number of prevalent cases is the total number of cases of disease existing in a population. P=total number of cases of a disease/total population Mortality is another term for death. A mortality rate is the number of deaths due to a disease divided by the total population. M=deaths/total population Incidence is a measure of disease that allows us to determine a person’s probability of being diagnosed w a disease during a given period of time. I=newly diagnoses cases of a disease. Incidence rate = number of new cases of a disease/number of persons at risk. It is the number of newly diagnoses cases of a disease. Incidence- 5 women have cancer/population of 200 females=0.025 or 2500 oer 100000 (probability of being dx w a disease within a given time) Prevalence- total pop of 40000 and 1200 were recently dx w cancer, and 3500 have cancer, prevalence is total number with cancer/total pop (4700/40000=0.1175 or 0.1175x100000=11750 per 100000). Mortality – 25 deaths due to lung cancer/30000 = number x 100000
