Study Notes

Community Health Nursing Key Concepts

Intermediate Factors: Characteristics affecting health are classified as biological (age, sex, immunity), behavioral (habits, culture), and social (attitudes, norms).
Disease Agent: Causes of disease can include biological agents (parasites, bacteria, viruses) and chemical or physical agents.
Environment Categories: Environment influences health and is categorized into physical, biological, and socio-economic factors.
Host: Refers to a susceptible human affected by health agents.

Ecological Triad

Multiple Theory of Disease Causation: Describes interactions between agents, hosts, and environments leading to disease.
Epidemiologic Triad: Simplest form showing the relationship between an external agent, susceptible host, and enabling environment for disease transmission.

Evaluation Types

Evaluation: Systematic assessment of program compliance and success.
Outcome Evaluation: Gauges the extent of program's accomplishment regarding intended results and measures effects in target populations.
Impact Evaluation: Assesses effectiveness in achieving ultimate goals through comparison of different groups or the same group over time.

Key Terminologies in Epidemiology

Epidemiology: Study of health-related states, their distribution, and determinants in populations for controlling health issues.
Fomites: Inanimate objects capable of harboring pathogens (e.g., contaminated air, soil, food).
Reservoirs: Inanimate environments where pathogens can spread (air, soil, water).

Health Statistics and Organizations

Philippine Statistics Authority (PSA): Collects and publishes statistical data on various aspects of the Philippine society.
World Health Organization (WHO): A UN agency dedicated to global public health.

Recent Health Concerns

Dengue Incidence: Reported to be 85% higher in early 2019 than in 2018, prompting a National Dengue Alert by the Department of Health (DOH).
Vaccination Gaps: Decline in immunization coverage affecting susceptible populations, particularly children.

Additional Public Health Concepts

Case Definition: Standard criteria for classifying health conditions.
Determinants of Health: Factors influencing health include biological, chemical, social, and economic influences.
Herd Immunity: Probability of a community developing an epidemic when exposed to an infectious agent.
Host as Victim: The individual or group that might contract a disease.

Survey Methodology

PRECEDE-PROCEED Model: Developed by Dr. Lawrence Green for community health program evaluation.
Predisposing Factors: Characteristics that motivate health-related behavior, including attitudes and beliefs.
Data Collection: Utilizes survey forms based on community needs to assess health behaviors and conditions.
