A comprehensive overview of population health, including key concepts such as health, homeostasis, human potential, and harmony. It delves into the nine key elements of a population health approach, the four sub-concepts of population health (health promotion, illness and injury prevention, chronic disease management, and epidemiology), and the role of nurses in addressing health inequities. The document also covers primary care, primary health care, the distinction between illness and disease, the determinants of health (doh), and the social determinants of health (sdoh). Additionally, it explores critical thinking approaches (upstream, midstream, and downstream), the levels of prevention (primary, secondary, and tertiary), and the expanded chronic care model. The document concludes by discussing morbidity, mortality, the epidemiological triad, and the chain of infection, as well as the 5 a's in chronic disease self-management (cdsm) support.

Health - ✔✔state of complete physical, mental and social well-being and not merely the absence of disease or infirmity Homeostasis - ✔✔Maintenance of physiological, functional, & social norms leading to adaptation & homeostasisFeeling in control over one's life and living conditions Human potential - ✔✔Actualization of human potential through goal-directed behaviour, competent self-care & satisfying relationships with othersHaving a sense of purpose Harmony - ✔✔Adjustment to maintain structural integrity & harmony with relevant environmentsFeeling connected to the community Community definition - ✔✔People & relationships Share = agencies, institutions, physical environment Defined by = geography common interest or focus shared status or special interest groupCan be a client population - ✔✔eg. School of health sciences aggregate - ✔✔Groups that form a population. eg. BCIT student in BSN program Population health - ✔✔Measured by determinants of health (DoH) & health status indicators Improves the health of populations & decreased inequitiesScope consists of the following 5 elements - think of these as clients ( individuals, families, groups, communities, population)
9 key elements of a population health approach - ✔✔1. focuses on the health of populations
Nursing diagnosis - ✔✔Nurses [non NPs]. Describes health care problems via clinical judgement. Diagnoses actual & potential health problems within the domain of nursing. More in Nursing Practice. Nurses do NOT diagnose a medical condition or a disease, unless they are a nurse practitioner DoH - ✔✔Broad range of personal, social, economic, and environmental factors that determine individual and population health. Factors that influence the risk for or distribution of health outcomes. Generally 12. SDoH - ✔✔Social conditions and broader forces - politics and economics. Interact to influence risks to health and well-being. Affect how vulnerable or resilient people are to disease and injury. Mikkonen & Raphael - consider 14 SDoH. Critical thinking - ✔✔1.Upstream thinking 2.Midstream thinking 3.Downstream thinking Midstream thinking - ✔✔policies intended for regional, local, community, or organizational entities Upstream thinking - ✔✔beyond the individual ... more like a big picture Downstream thinking - ✔✔individual curative stance ... negates viewing the influences of sociopolitical, economic, and/or environmental circumstances Primary prevention - ✔✔activities that prevent the development of a disease based on the natural history of a disease or an injury. No pathology (prepathogenesis stage)------> susceptible to disease or injury
Secondary prevention - ✔✔activities that detect disease early in its progression (pathogenesis stage) / before clinical signs and symptoms become apparent to make a diagnosis & begin treatment Screening helps determines likelihood that disease will develop. tertiary prevention - ✔✔activities in middle and later periods of pathogenesis. Goals: interrupt disease's course, reduce disability & begin rehabilitation. Can be delivered in specialized clinics, hospitals, rehab centres, community and primary care settings Chronic Disease Management - ✔✔DoH & the levels of prevention equipping client to manage their condition building upon their strengths. Periodical interactions with HC system and/or informal support systems. Client centered approach, integrated across sectors & comprehensive Expanded Chronic Care Model - ✔✔a) Health system and community b) Self-management / personal skills c) Delivery system design / re-orient health services d) Decision support e) Information systems f) Healthy public policy g) Supportive environments h) Community action. Morbidity - ✔✔Occurrence of disease in a populationIncludes incidence and prevalence rates. Assists with articulating distribution of diseases & health outcomes within populations. DISEASE Mortality - ✔✔indicates the number of deaths in a population. Helps with identifying and understanding health issues, at-risk populations & required health services. DEATH Epidemiological Triad - ✔✔agent, host, environment
advise - ✔✔- Provide specific personalized information about health risks and benefits of change
