Public health nursing
The practice of promoting and protecting the health of populations using knowledge from nursing, social, and public health sciences.
Core Functions of Public Health
● Assessment
● Assurance
● Policy development
Primary prevention
aims to prevent disease or injury before it ever occurs.
● education about healthy and safe habits
● Immunization
● legislation and enforcement to ban or control the use of hazardous products (e.g. asbestos) or to mandate safe and healthy practices
Secondary prevention
aims to reduce the impact of a disease or injury that has already occurred. detecting and treating disease or injury as soon as possible to halt or slow its progress, encouraging personal strategies to prevent reinjury or recurrence, and implementing programs to return people to their original health and function to prevent long-term problems
● regular exams and screening tests to detect disease
● daily, low-dose aspirins and/or diet and exercise programs to prevent further heart attacks or strokes
● Suitably modified work so injured or ill workers can return
Tertiary prevention
-aims to soften the impact of an ongoing illness or injury that has lasting effects.helping people manage long-term, often-complex health problems and injuries (e.g. chronic diseases, permanent impairments) in order to improve as much as possible their ability to function, their quality of life and their life expectancy.
● cardiac or stroke rehabilitation programs
● support groups
● vocational rehabilitation programs
Epidemiology
Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems.
Incidence of disease
the number of newly diagnosed cases of a disease

Public Health Nursing vs Regular Nursing
- The client is the population
- Obligation: the greatest good for the greatest # of people as a whole
- Working with the client as an equal partner
- Primary prevention is priority in selecting appropriate activities.
- Strategies that create healthy environmental, social, economic conditions in which populations may thrive.
- Identify and reach out to all who might benefit from a service
- Optimal use of resources to assure best overall improvement in health of population
- Collaboration with other professionals, organizations
Assessment of PBH
Review of concerns, strengths, expectations of population
-Guided by epidemiological methods and the nursing process
Assurance of PBH
Quality/Accessibility/Effectiveness/Acceptability/Availability
-Accomplished through:
Regulation
-Advocating for other healthcare professionals
Coordinating community services/direct provision

According to
- Results of Assessment
- Priorities set by the population
- Consideration of sub-population and communities at risk

The study of
Epidemiology assumes
illness does not occur randomly in a population but when the right accumulation of risk factors or determinants exists.
Descriptive Epidemiology
•Focuses on the distribution of frequencies and patterns of health events with groups in a population, according to: ◦Who ◦Where ◦When ◦What
Analytic Epidemiology
Seeks to identify associations between a particular disease or health problem and its etiology, directed toward finding answers to:
◦How
◦Why
Epidemiologist’s focus:
◦Identifying the exposure or source that caused the illness (dis-ease)
◦The number of other persons who may have been similarly exposed
◦The potential for further spread in the community
◦Interventions to prevent additional cases or recurrences
suggested environmental and host factors such as behaviors might influence the development of disease
