Defining Public Health
- Public health is the science and art of preventing disease, prolonging life, and promoting health through the organized efforts of society.
- It focuses on the health of entire populations, not just individual patients.
- The key distinction is the focus on prevention rather than treatment.
- It addresses the underlying social, economic, and environmental factors that influence health.
- A CPHP applies their pharmacy expertise to achieve these broad public health goals.
The Three Core Functions
- The Institute of Medicine (IOM) defined three core functions of public health.
- 1. Assessment: The systematic collection, analysis, and dissemination of information on the health of the community.
- 2. Policy Development: The use of scientific knowledge to develop comprehensive public health policies.
- 3. Assurance: Assuring that the services necessary to achieve agreed-upon goals are provided, either by encouraging other entities or by providing services directly.
- These three functions provide the overall framework for public health practice.
The 10 Essential Public Health Services (Assessment)
- These services operationalize the three core functions.
- 1. Assess and monitor population health status, factors that influence health, and community needs and assets. (e.g., analyzing BRFSS data).
- 2. Investigate, diagnose, and address health problems and hazards affecting the population. (e.g., conducting an outbreak investigation).
- A CPHP uses data skills to support these assessment functions.
The 10 Essential Public Health Services (Policy Development)
- 3. Communicate effectively to inform and educate people about health, factors that influence it, and how to improve it. (e.g., a public health campaign on naloxone).
- 4. Strengthen, support, and mobilize communities and partnerships to improve health. (e.g., partnering with community organizations on a diabetes prevention program).
- 5. Create, champion, and implement policies, plans, and laws that impact health. (e.g., advocating for smoke-free air laws).
- 6. Utilize legal and regulatory actions designed to improve and protect the public’s health. (e.g., enforcing pharmacy regulations).
The 10 Essential Public Health Services (Assurance)
- 7. Assure an effective system that enables equitable access to the individual services and care needed to be healthy. (e.g., operating a public health clinic).
- 8. Build and support a diverse and skilled public health workforce. (e.g., training and credentialing).
- 9. Improve and innovate public health functions through ongoing evaluation, research, and continuous quality improvement. (e.g., evaluating the effectiveness of a new program).
- 10. Build and maintain a strong organizational infrastructure for public health.
- A CPHP can contribute to all of these essential services.
Block 2: Core Public Health Sciences
Defining Epidemiology
- Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations.
- It is the basic science of public health.
- It is often called the "public health detective," as it seeks to find the causes of disease.
- A CPHP must have a strong foundational understanding of epidemiological principles.
- Pharmacoepidemiology is a subfield that applies these principles to the study of medication effects in populations.
Measures of Disease Frequency
- Prevalence: The proportion of a population that has a disease at a specific point in time. It measures the existing burden of disease. (Prevalence = Number of existing cases / Total population).
- Incidence: The rate at which new cases of a disease occur in a population over a specific period of time. It measures the risk of developing a disease. (Incidence Rate = Number of new cases / Person-time at risk).
- A CPHP must be able to calculate and interpret these fundamental measures.
Study Designs
- Descriptive Studies (Case Report, Cross-Sectional): Used to describe the distribution of disease. They cannot determine causality.
- Analytic Studies (Cohort, Case-Control): Used to test hypotheses about the determinants of disease.
- Cohort Study: Follows a group of people over time to compare the incidence of disease in those who are exposed versus unexposed to a risk factor.
- Case-Control Study: Compares the past exposures of people with a disease (cases) to those without the disease (controls).
- Randomized Controlled Trial (RCT): The "gold standard" experimental design.
Measures of Association
- These statistics are used to quantify the relationship between an exposure and a disease.
- Relative Risk (RR): Calculated from a cohort study. It is the ratio of the incidence in the exposed group to the incidence in the unexposed group.
- Odds Ratio (OR): Calculated from a case-control study. It is the ratio of the odds of exposure in the cases to the odds of exposure in the controls.
- An RR or OR > 1 suggests a positive association (the exposure is a risk factor).
- An RR or OR < 1 suggests a negative association (the exposure is protective).
Bias and Confounding
- A CPHP must be able to critically evaluate a study for potential errors.
- Bias: A systematic error in a study that results in a mistaken estimate of the exposure-disease relationship. Common types include selection bias and information bias.
- Confounding: A third factor that is associated with both the exposure and the disease, which can distort the true relationship.
- For example, smoking is a confounder in a study of alcohol and lung cancer.
- Statistical methods can be used to control for confounding, but not for bias.
Defining Health Disparities and Health Equity
- Health Disparities: Preventable differences in the burden of disease, injury, or opportunities to achieve optimal health that are experienced by socially disadvantaged populations.
- Health Equity: The principle that everyone has a fair and just opportunity to be as healthy as possible.
- Achieving health equity requires removing obstacles to health such as poverty, discrimination, and their consequences.
- The reduction of health disparities is a central goal of public health.
Social Determinants of Health (SDoH)
- SDoH are the conditions in the environments where people are born, live, learn, work, and play that affect health.
- They are the root causes of many health disparities.
- The five key domains of SDoH are:
- 1. Economic Stability.
- 2. Education Access and Quality.
- 3. Health Care Access and Quality.
- 4. Neighborhood and Built Environment.
- 5. Social and Community Context.
- A CPHP must understand how these factors impact medication-related outcomes.
The Pharmacist's Role in Addressing SDoH
- Pharmacists can play a key role in identifying and addressing SDoH-related barriers to medication access.
- This can include screening for food insecurity, transportation challenges, and low health literacy.
- They can connect patients with community resources to help address these needs.
- This requires moving beyond the traditional dispensing role to a more holistic, public health-oriented practice.
- A CPHP is a leader in integrating SDoH screening into pharmacy workflow.
Cultural Competency
- Cultural competency is the ability to provide care to patients with diverse values, beliefs, and behaviors.
- It is a key strategy for reducing health disparities.
- It involves being aware of one's own cultural worldview and being open to understanding the patient's perspective.
- It also requires providing care that is linguistically appropriate, such as using qualified medical interpreters.
- A CPHP must be a culturally competent practitioner.
Analyzing Data for Disparities
- A key role for a public health analyst is to use data to identify and monitor health disparities.
- This involves stratifying health outcome data (e.g., medication adherence rates) by race, ethnicity, socioeconomic status, and geography.
- This analysis makes disparities visible and allows for the targeting of interventions.
- For example, if the data shows that adherence to diabetes medications is much lower in a specific zip code, resources can be directed to that community.
- A CPHP must be skilled at this type of equity-focused data analysis.
The Role of Policy in Public Health
- Policy is one of the most powerful tools for improving the health of a population.
- Policies can change the environment to make healthy choices the easy choices (e.g., smoke-free air laws).
- They can also improve access to care (e.g., the Affordable Care Act).
- A CPHP must understand how policy is made and how it can be used to advance public health goals.
- This is the "Policy Development" core function of public health.
The Legal Basis for Public Health
- Public health law is the body of law that gives government the authority to protect the public's health.
- In the U.S., the primary authority for public health rests with the states (the "police power").
- This is why state and local health departments have the authority to do things like issue quarantine orders.
- The federal government's authority comes primarily from its power to regulate interstate commerce.
- A CPHP should understand this legal framework.
The Legislative Process
- A CPHP should understand the basic process of how a bill becomes a law.
- This involves introduction, committee review, floor debate and votes in both chambers of the legislature, and finally, signature by the executive (governor or president).
- Understanding this process is essential for effective advocacy.
- It allows an advocate to know the key points in the process where they can have the most influence.
The Regulatory Process (Rulemaking)
- When a law is passed, it often gives a government agency (like the Department of Health) the authority to write the specific rules to implement it.
- This is done through a formal "rulemaking" process.
- The agency must publish a proposed rule and allow for public comment before issuing a final rule.
- The public comment period is a key opportunity for pharmacists and other stakeholders to provide their expert input.
- A CPHP can play a key role in analyzing and commenting on proposed rules.
Advocacy
- Advocacy is the process of influencing public policy.
- It involves educating policymakers about a problem and proposing a solution.
- Pharmacists can be powerful advocates for public health policies.
- This can be done through professional associations like APhA and ASHP.
- It can also be done at the individual level by building relationships with local elected officials.
- A CPHP should be an active advocate for policies that improve the public's health.
Block 3: Public Health Pharmacy Practice
Accessibility of Pharmacists
- Pharmacists are the most accessible healthcare professionals in many communities.
- Over 90% of Americans live within 5 miles of a community pharmacy.
- Patients see their pharmacist much more frequently than their primary care provider.
- This accessibility makes pharmacists an ideal partner for public health initiatives.
- They are a trusted source of health information in the community.
Screening Services
- Pharmacists can provide a wide range of public health screening services.
- This includes screening for chronic diseases like hypertension, diabetes, and dyslipidemia.
- They can also screen for infectious diseases like HIV and Hepatitis C.
- Screening for mental health and substance use disorders is another key role.
- The CPHP is a leader in designing and implementing these screening programs in the pharmacy setting.
Immunizations
- Pharmacists are now one of the leading providers of immunizations in the United States.
- They are authorized to administer a wide range of vaccines to adults in all 50 states.
- Their accessibility makes them a crucial partner in improving vaccination rates for influenza, pneumonia, shingles, and many other diseases.
- The CPHP is often involved in the public health planning for vaccination campaigns.
Patient Education
- Patient education is a core function of a pharmacist.
- In a public health role, this education extends beyond the individual to the entire community.
- A CPHP may be involved in creating and delivering public health educational campaigns.
- This can include topics like smoking cessation, naloxone use, and the safe disposal of medications.
- This is a key part of the "inform and educate" essential service.
Collaborative Practice
- Pharmacists can work under collaborative practice agreements (CPAs) with physicians to manage the care of patients with chronic diseases.
- This team-based approach has been shown to improve outcomes for conditions like diabetes and hypertension.
- From a public health perspective, these models can be a powerful way to improve the management of chronic disease at a population level.
- A CPHP is an advocate for policies that expand the scope of practice and allow for these innovative models of care.
Levels of Prevention
- Prevention is the cornerstone of public health. There are three levels of prevention.
- Primary Prevention: Aims to prevent a disease before it ever occurs (e.g., immunizations, smoking cessation).
- Secondary Prevention: Aims to reduce the impact of a disease that has already occurred by detecting and treating it early (e.g., screening for hypertension, cancer screening).
- Tertiary Prevention: Aims to soften the impact of an ongoing illness or injury that has lasting effects (e.g., chronic disease management, rehabilitation).
- A CPHP is involved in programs at all three levels.
Health Promotion
- Health promotion is the process of enabling people to increase control over and to improve their health.
- It is a proactive approach that focuses on building assets and strengths.
- It addresses the underlying social determinants of health.
- Pharmacists can be key health promoters in their communities.
- This can involve partnering with local organizations to promote healthy behaviors.
The U.S. Preventive Services Task Force (USPSTF)
- The USPSTF is an independent panel of national experts in prevention and evidence-based medicine.
- They make evidence-based recommendations about clinical preventive services such as screenings, counseling services, and preventive medications.
- Their recommendations are assigned a letter grade (A, B, C, D, or I).
- Under the ACA, most health plans are required to cover services with an "A" or "B" rating at no cost to the patient.
- A CPHP must be an expert on the USPSTF recommendations.
The Pharmacist's Role in Prevention
- Pharmacists contribute to all three levels of prevention.
- Primary: Providing immunizations and tobacco cessation services.
- Secondary: Conducting screenings for blood pressure and diabetes.
- Tertiary: Providing MTM and chronic disease management to prevent complications.
- A CPHP works to integrate these preventive services into routine pharmacy practice.
Behavior Change Theories
- To be effective at health promotion, a CPHP should be familiar with theories of health behavior change.
- The Transtheoretical Model (Stages of Change): Views change as a process through stages (Precontemplation, Contemplation, Preparation, Action, Maintenance). Interventions should be matched to the patient's stage.
- Health Belief Model: Suggests that a person's belief in a personal threat of an illness, together with their belief in the effectiveness of the recommended behavior, will predict the likelihood of the behavior.
- Motivational Interviewing: A counseling style that helps patients to explore and resolve their own ambivalence about change.
Defining Health Literacy
- Health literacy is the degree to which individuals have the ability to find, understand, and use information and services to inform health-related decisions.
- It is not just about the ability to read; it also includes numeracy and communication skills.
- Nearly 9 out of 10 adults have difficulty using the everyday health information that is routinely available.
- Low health literacy is associated with poor health outcomes.
- A CPHP must be a champion for health literacy.
The Universal Precautions Approach
- It is not possible to tell a person's health literacy level by looking at them.
- Therefore, the "Universal Precautions" approach should be used.
- This means assuming that all patients may have difficulty understanding health information.
- All communication, both verbal and written, should be made as clear and simple as possible for everyone.
- This is a key strategy for patient safety.
Plain Language and Clear Communication
- Plain language is communication that your audience can understand the first time they read or hear it.
- This involves avoiding medical jargon and using simple words and short sentences.
- The "teach-back" method is a key tool for clear verbal communication. This involves asking the patient to explain in their own words what they need to know or do.
- A CPHP must be an expert at using these clear communication techniques.
Cultural Competency
- Cultural competency is the ability to provide care to patients with diverse values, beliefs, and behaviors.
- It is a key strategy for reducing health disparities.
- It involves being aware of one's own cultural worldview and being open to understanding the patient's perspective.
- It requires providing care that is respectful of and responsive to the patient's cultural background.
Linguistic Competency
- This is the ability to provide care to patients with limited English proficiency.
- It is a key part of cultural competency.
- It requires providing access to qualified medical interpreters. Using family members as interpreters is not appropriate.
- Written materials, such as prescription labels and patient education, should be available in the primary languages of the community being served.
- A CPHP advocates for these resources to be available in their practice setting.
The Role of Communication in Public Health
- Effective communication is one of the 10 Essential Public Health Services.
- It is the process of informing, educating, and empowering people about health issues.
- It is a key tool for health promotion and disease prevention.
- A CPHP is often a key messenger in public health communication campaigns.
Health Communication Campaigns
- A health communication campaign is an organized effort to communicate a specific health message to a target audience.
- The campaign should be based on a clear understanding of the audience's knowledge, attitudes, and behaviors.
- It should use a variety of communication channels to reach the audience.
- The message should be clear, simple, and consistent.
- A CPHP may be involved in the design and implementation of these campaigns at the local level.
Risk Communication
- Risk communication is a specific type of health communication used in emergencies and outbreaks.
- The goal is to provide the public with the information they need to make the best possible decisions about their health in a time of uncertainty.
- Key principles of risk communication include being first, being right, and being credible.
- It requires communicating with transparency, empathy, and respect.
- A CPHP may be a key spokesperson during a public health emergency.
Working with the Media
- The media is a powerful partner for disseminating public health messages.
- A CPHP may be asked to serve as a subject matter expert for interviews with journalists.
- It is essential to have a clear and consistent message.
- The pharmacist should be prepared to answer difficult questions.
- Building relationships with local health reporters can be a valuable strategy.
Social Media and Digital Communication
- Social media is now a key channel for public health communication.
- It allows for the rapid dissemination of information to a wide audience.
- However, it is also a major source of health misinformation.
- A key role for a CPHP is to be a credible and evidence-based voice on social media.
- They can use these platforms to share accurate health information and to counter misinformation.
- This is a new and important part of modern public health practice.
Purpose of a CHNA
- A CHNA is a systematic process for identifying the key health needs and assets of a community.
- It is the foundation for all community health improvement planning.
- It is a key part of the "Assessment" core function of public health.
- Under the ACA, all non-profit hospitals are required to conduct a CHNA every three years.
- The CPHP is a key stakeholder who can provide valuable input to this process.
The CHNA Process
- The process involves collecting and analyzing data from a variety of sources.
- It must include input from the community, especially from medically underserved, low-income, and minority populations.
- The process culminates in a formal report that identifies the community's significant health needs.
- The hospital must then develop an implementation strategy that describes how it will address these needs.
Quantitative Data Sources
- The CHNA uses quantitative data to describe the health of the community.
- This includes data on leading causes of death and disease prevalence.
- It also includes data on health behaviors from surveys like the BRFSS.
- Data on SDoH, such as poverty and education levels, is also analyzed.
- A CPHP can help to analyze and interpret the data related to medication use and access.
Qualitative Data Sources
- Qualitative data is essential for understanding the community's perspective.
- This is gathered through methods like community forums, focus groups, and key informant interviews.
- This process allows community members to share their own stories and to identify the health issues that are most important to them.
- The CPHP can be a key participant in these community engagement activities.
The Pharmacist's Role in the CHNA
- As a highly accessible provider, the pharmacist has a unique understanding of the community's health needs.
- They can provide valuable input on medication-related issues, such as affordability and access.
- They can be a key informant in the data collection process.
- After the CHNA is completed, the CPHP can be a leader in developing and implementing pharmacy-based programs to address the identified needs.
- This is a key opportunity for the pharmacy to demonstrate its value to the community.
Block 4: Infectious Disease & Emergency Preparedness
The Pharmacist's Role as an Immunizer
- Pharmacists are a key part of the nation's immunization infrastructure.
- All 50 states now authorize pharmacists to administer a wide range of vaccines to adults.
- The accessibility of pharmacies makes them a crucial partner for improving vaccination rates.
- A CPHP is a leader in the design and implementation of pharmacy-based immunization programs.
- They are experts on vaccine storage, handling, and administration.
The Advisory Committee on Immunization Practices (ACIP)
- The ACIP is a committee of medical and public health experts that provides recommendations to the CDC on the use of vaccines in the U.S.
- They develop the official, evidence-based adult and childhood immunization schedules.
- A CPHP must be an expert on the current ACIP recommendations.
- These recommendations are the foundation of all immunization practice.
Vaccine Hesitancy
- Vaccine hesitancy, the reluctance or refusal to vaccinate despite the availability of vaccines, is a major public health threat.
- It is fueled by misinformation and disinformation, especially on social media.
- Pharmacists are a trusted source of information and are in a key position to address vaccine hesitancy.
- This requires using empathetic communication and motivational interviewing techniques.
- The goal is to have a respectful conversation, not an argument.
- A CPHP should be skilled in these communication strategies.
Vaccine Storage and Handling
- Vaccines are fragile biological products that must be stored at the correct temperatures to remain effective.
- This is known as the "cold chain."
- The CDC has a detailed "Vaccine Storage and Handling Toolkit" that provides the standards for this.
- This includes requirements for the use of pharmaceutical-grade refrigerators and continuous temperature monitoring.
- A CPHP is responsible for ensuring their program is fully compliant with these standards.
Vaccine Adverse Event Reporting System (VAERS)
- VAERS is a national early warning system to detect possible safety problems in U.S.-licensed vaccines.
- It is co-managed by the CDC and FDA.
- Healthcare providers are required to report certain adverse events after vaccination.
- Anyone can submit a report to VAERS.
- It is important to understand that VAERS reports are not proof that a vaccine caused an event, only that the event occurred after vaccination.
- A CPHP must know when and how to report to VAERS.
The Pharmacist's Role in STI Prevention
- Pharmacists are in a key position to provide education and services for STI prevention.
- This includes counseling on safe sex practices and the correct use of condoms.
- They are also key providers of vaccinations for preventable STIs, such as HPV and Hepatitis B.
- In some states, pharmacists can now prescribe and dispense pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) for HIV.
- A CPHP is a leader in these public health initiatives.
Expedited Partner Therapy (EPT)
- EPT is the clinical practice of treating the sex partners of patients diagnosed with an STI without the partner first being examined.
- This is a key public health strategy to reduce reinfection and curb the spread of STIs like chlamydia and gonorrhea.
- This is legal in most states.
- It typically involves the provider giving the patient a prescription or medications to give to their partner.
- A CPHP should be an advocate for and an expert on the local laws and procedures for EPT.
HIV Pre-Exposure Prophylaxis (PrEP)
- PrEP is the use of antiretroviral drugs by HIV-negative individuals to prevent HIV infection.
- It is a highly effective prevention tool for individuals at high risk.
- The most common regimen is a once-daily oral pill containing tenofovir and emtricitabine.
- A long-acting injectable formulation is also now available.
- A CPHP is a key provider of PrEP services, from identifying candidates to managing the therapy.
HIV Post-Exposure Prophylaxis (PEP)
- PEP is the use of antiretroviral drugs after a single high-risk event to prevent HIV infection.
- It must be started as soon as possible after the exposure, and always within 72 hours.
- It involves taking a 28-day course of antiretroviral medications.
- A CPHP should be an expert on the guidelines for both occupational and non-occupational PEP.
CDC Treatment Guidelines
- The CDC publishes comprehensive, evidence-based guidelines for the treatment of STIs.
- These guidelines are the standard of care.
- They are updated regularly to reflect new evidence and changing resistance patterns.
- A CPHP must be an expert on the latest version of these guidelines.
- They are the primary resource for all aspects of STI management.
The Role of the Epidemiologist
- An outbreak investigation is the core work of a field epidemiologist, or "disease detective."
- The investigation is a systematic process to confirm that an outbreak is occurring, identify the cause, and implement control measures.
- A CPHP may be a key member of the outbreak investigation team, especially if it involves a foodborne or waterborne illness where medications may be needed.
Steps of an Outbreak Investigation
- There is a standard, multi-step process for an investigation.
- 1. Prepare for fieldwork.
- 2. Establish the existence of an outbreak.
- 3. Verify the diagnosis.
- 4. Construct a case definition.
- 5. Find cases systematically and record information.
- 6. Perform descriptive epidemiology (person, place, time).
- 7. Develop hypotheses.
- 8. Evaluate hypotheses epidemiologically.
- 9. Implement control and prevention measures.
- 10. Communicate findings.
Descriptive Epidemiology (Person, Place, Time)
- This is the process of characterizing the outbreak.
- Person: Who is getting sick? (Age, sex, etc.)
- Place: Where are they getting sick? (Geographic location)
- Time: When are they getting sick? (The "epi curve").
- An epidemic curve, or epi curve, is a graph that plots the number of cases over time. The shape of the curve can provide clues about the type of outbreak.
- A CPHP should be able to interpret an epi curve.
The Pharmacist's Role in an Outbreak
- Pharmacists can be an early warning system for an outbreak.
- An unusual increase in the dispensing of certain medications (e.g., anti-diarrheals) can be the first sign of a community outbreak. This is known as syndromic surveillance.
- The pharmacist is also a key player in the response.
- This includes ensuring an adequate supply of the necessary medications (e.g., antibiotics for a bacterial outbreak).
- They also serve as a key source of information for the public.
Point-of-Dispensing (POD) Sites
- In a large-scale outbreak or a bioterrorism event, a key response strategy is to set up Points of Dispensing (PODs).
- These are temporary sites, often in community locations like schools, where medications or vaccines can be dispensed to a large number of people quickly.
- Pharmacists are the clinical leaders of these PODs.
- A CPHP is often involved in the public health planning and drills for these POD operations.
The Threat of Antimicrobial Resistance
- Antimicrobial resistance is one of the biggest public health challenges of our time.
- Bacteria and other microbes are evolving to become resistant to the drugs we use to treat them.
- This can make common infections difficult or impossible to treat.
- The primary driver of resistance is the overuse and misuse of antibiotics.
- A CPHP must be a leader in the fight against antimicrobial resistance.
Core Elements of Antimicrobial Stewardship Programs (ASPs)
- The CDC has outlined Core Elements for both hospital and outpatient ASPs.
- Key elements include leadership commitment, accountability, drug expertise (pharmacist leadership), and action.
- Other elements are tracking and reporting of antibiotic use and resistance patterns.
- Education of clinicians and patients is also a critical component.
- A CPHP can help to design and implement these programs in various practice settings.
Key Stewardship Interventions
- Prospective Audit and Feedback: A pharmacist prospectively reviews antibiotic orders and provides real-time recommendations to the prescriber.
- Formulary Restriction: Certain broad-spectrum antibiotics require pre-approval from the stewardship team.
- Education: Providing education to prescribers on appropriate antibiotic use.
- Development of Clinical Guidelines: Creating local, evidence-based guidelines for the treatment of common infections.
- A CPHP can be involved in all of these interventions.
The Role of the Antibiogram
- An antibiogram is an annual summary of the susceptibility patterns of local bacterial isolates.
- It is a critical tool for guiding empiric antibiotic selection.
- It helps clinicians to choose an antibiotic that is likely to be effective against the local pathogens.
- The CPHP is involved in the creation and dissemination of the antibiogram.
- They can also use it to track changes in resistance patterns over time.
The "One Health" Approach
- "One Health" is a collaborative, multisectoral approach to health that recognizes the interconnection between people, animals, plants, and their shared environment.
- In the context of antimicrobial resistance, this is a critical concept.
- A large percentage of all antibiotics are used in agriculture.
- This use contributes to the development of resistant bacteria that can then spread to humans.
- A comprehensive public health approach to stewardship must address antibiotic use in both humans and animals.
- A CPHP should be an advocate for this "One Health" perspective.
The Pharmacist's Role in Disasters
- Pharmacists are critical members of the emergency response team.
- They are medication experts who are essential for managing the pharmaceutical supply chain during a disaster.
- They also serve as a key source of information for the public.
- A CPHP is often a leader in the public health planning for emergencies.
The Emergency Operations Plan (EOP)
- Every public health agency and healthcare organization must have a formal EOP.
- This plan details how the organization will respond to a wide range of potential disasters.
- The CPHP is a key author of the pharmacy-specific annex of this plan.
- The plan must be practiced through regular drills and exercises.
- This is part of the "Assurance" core function of public health.
The Strategic National Stockpile (SNS)
- The SNS is the nation's largest supply of life-saving pharmaceuticals and medical supplies for use in a public health emergency severe enough to cause local supplies to run out.
- The SNS is a federal asset, but it is distributed and dispensed at the state and local level.
- A CPHP is a key leader in the local planning for how to receive, secure, and dispense these SNS assets.
Points of Dispensing (PODs)
- In a large-scale emergency, a key strategy is to set up Points of Dispensing (PODs).
- These are temporary sites, often in community locations like schools, where medications or vaccines can be dispensed to a large number of people quickly.
- Pharmacists are the clinical leaders of these PODs.
- A CPHP is often involved in the public health planning and drills for these POD operations.
- They are experts on the operational logistics of a mass dispensing campaign.
The Incident Command System (ICS)
- The ICS is a standardized management system designed to enable effective and efficient incident management.
- It is used by all levels of government to manage emergencies.
- A CPHP should be trained in the basic principles of ICS.
- This allows them to effectively integrate into the broader emergency response structure.
- In the ICS structure, the pharmacy would typically fall under the Logistics Section.
Block 5: Chronic Disease & Substance Use
The Burden of CVD
- CVD is the leading cause of death in the United States.
- It is a major driver of healthcare costs.
