Community and Population Health Intervention Review

Community health encompasses activities and strategies specifically designed to increase the health of a community population. These interventions often focus on preventing hospitalizations from conditions that are manageable or preventable.
Examples of community interventions include:
- COVID-19 Mitigation: Requiring masks near hospitals to prevent the spread of the virus and reduce the volume of hospitalizations.
- Food Deserts: Addressing areas with no healthy food options by partnering with local grocery stores to provide low-cost, healthy food.
- Federal Policy and Nutrition: Ensuring SNAP (Supplemental Nutrition Assistance Program) benefits remain robust to help families face rising food costs.
- West Houses and Greenwich Houses Examples: Community-oriented places that implement strategies to decrease hospitalizations from preventable conditions.
Types of Community-Based Activities:
- Stress Reduction: Implementing specific dietary changes to decrease stress levels.
- Physical Activity: Organized workout programs and Tai Chi classes.
- Elderly Engagement: Music classes where the elderly can listen to music, hang out, and sing to promote social well-being.
- Cardiovascular Monitoring: Blood pressure screenings to identify hypertension early. Identifying high blood pressure allows for medical referrals, which prevent admissions in emergency situations such as heart attacks or strokes.

Interventions are categorized into three distinct levels, which can be easily recalled using the first letter of each level:
- Primary ( $P$ ): Prevention. These are actions taken to prevent a disease or condition from happening in the first place.
- Secondary ( $S$ ): Screening. This involves checking for the presence of a disease. Examples include blood pressure screenings and Pap smears.
- Tertiary ( $T$ ): Treatment. This level focuses on treating a disease, managing its burden, or clinical treatment after a condition has manifested.

Vulnerability in Disasters: When a disaster occurs, individuals in the poorest conditions or those with low socioeconomic status ( $SES$ ) are the most affected and therefore considered the most vulnerable.
Natural Disasters:
- Environmental Flooding: The most common type of natural disaster.
- Fire: Another frequently occurring natural disaster.
Active Shooter Preparation ( $Active Seizures$ ):
- Schools prepare children for active-use situations through lockdown drills.
- Specific drill activities include practicing hiding under desks and putting curtains down to limit visibility.
- The core principle of preparation is the necessity of consistent practice.

Vector-borne illnesses are diseases transmitted to humans by carriers known as vectors, typically mosquitoes or ticks.
Lyme Disease: The most common vector-borne illness in the United States ( $U.S.$ ).
West Nile Virus: Primarily spread through mosquito bites.
Malaria: Another significant vector-borne disease.
Mechanisms of Spread:
- The most common avenues of spreading include mosquito bites and tick bites.
- Prevention involves avoiding bites and controlling the environment where vectors breed.
Environmental Mitigation Strategies:
- Mosquitoes commonly breed in standing or distilled water.
- Removing puddles of water is a standard prevention method.
- Limitations of Control: While small puddles can be removed, large natural bodies of water like lakes cannot be drained for environmental control.

The epidemiological triad is a model used to understand the spread of diseases, consisting of the Agent, the Host, and the Environment.
Agent: The actual infectious cause of the disease. In the case of West Nile, the agent is the West Nile Virus.
Host: The organism that is hosting the virus, typically the human.
Environment: External factors that allow the agent and host to interact, such as water or specific locations where mosquitoes are clustered.
Vector Clarification:
- A vector is the actual carrying species that carries the disease (e.g., a mosquito for West Nile or a tick for Lyme disease).
- For the purposes of disease transmission discussion, the vector can be considered as part of the host side or the carrier mechanism.

Health in All Policies: A broad concept asserting that health considerations should be integrated into every type of policy and budget, including municipal, state, federal, or international levels. This applies to everything from high-level finance to janitorial services in schools.
Intersectionality: An active word in this context, highlighting how different social factors intersect to impact health.
Social Determinants of Health: The concept of HiAP existed long before the formal identification of social determinants of health.
Hierarchy of Interventions:
- Public Health: The initial overarching level dealing with broad issues (e.g., a cyclospora infection outbreak in the U.S.).
- Population Health: Partnering with specific organizations and companies to address health in specific groups (e.g., working with food chains to remove infected prepackaged lettuces from shelves).
- Community Health Interventions: Targeting specific populations with health messaging and localized actions within organizations.

Trauma-Informed Care is centered on creating a safe space and building trust with individuals, particularly those in vulnerable populations like displaced persons.
Core Competencies of TIC:
- Respect: Showing genuine respect and avoiding overtalking or talking "at" the individual.
- Non-threatening Behavior: Avoidance of threatening words or behaviors.
- Body Language: Maintaining non-threatening postures. Examples of threatening body language include standing over someone, standing too close, or having "closed" body language such as crossing arms or twisting hands.
- Communication Techniques: Utilizing open-ended questions to allow individuals the chance to express their feelings fully. This avoids the limitation of yes/no questions which can cut off a conversation.

Question: If there is a question regarding low socioeconomic status ( $SES$ ) for people most at risk, which level of prevention would you pick?
Answer: Primary prevention is the focus for risk reduction.
Question: In the case of West Nile Virus, what is the agent?
Answer: The agent is the virus itself. The mosquito is the vector. The environment is wherever the mosquitoes are located, such as near water.
Question: Could you provide an example of population health interventions vs. community health interventions?
Answer: Using the Cyclospora example, population health involves the broad partnership with food chains to remove infected lettuce across a group. Community health would be the specific messaging and interventions targeted at the local areas and specific populations impacted by that lettuce.
Question: What are the levels of health literacy?
Answer: There are three levels of health literacy. It is important to understand what is included in each level and how they are funded.
