Unit 2: Determining Priorities in Wellness & Health Promotion
Module Vocabulary and Key Questions
This unit emphasizes the systematic identification of priorities in wellness and health promotion. The following sections address essential concepts and guiding questions that support clinical decision-making, population health management, and evidence-based preventive care.
Evidence-Based Approaches to Primary Care
What is evidence-based practice, and why is it important in healthcare?
Evidence-based practice (EBP) refers to a structured clinical decision-making framework that combines the best available scientific evidence, clinician expertise, and individual patient preferences. The primary purpose of EBP is to improve patient safety, enhance clinical outcomes, reduce unwarranted practice variation, and promote cost-effective care. By grounding decisions in high-quality research, healthcare providers can deliver interventions that are both effective and ethically sound within diverse populations (Melnyk & Fineout-Overholt, 2019).
What are key elements of quantitative research designs and their distinguishing characteristics?
Quantitative research designs systematically collect numerical data to examine relationships, interventions, and outcomes. Common designs include randomized controlled trials (RCTs), cohort studies, and case-control studies. These designs differ in methodological rigor, degree of bias control, and strength of causal inference. RCTs are considered the gold standard due to randomization and control, whereas observational designs are valuable for studying risk factors, prognosis, and rare conditions. Evidence hierarchies and grading systems assist clinicians in determining the reliability and applicability of findings to practice.
How is evidence appraised using standard methods and grading scales?
Critical appraisal involves a multistep evaluation process to ensure research validity and relevance. Clinicians first define a clinical problem or practice gap, followed by a systematic review of available evidence. Studies are then assessed for methodological quality, consistency of results, and potential bias. Grading scales are applied to rank the strength of evidence, enabling informed decisions regarding practice changes or policy implementation.
What are common models used in implementation science?
Implementation science provides structured frameworks that facilitate the translation of research into routine clinical practice.
| Model Name | Description |
|---|---|
| Iowa Model of Evidence-Based Practice | Guides clinicians through problem identification, evidence appraisal, implementation, and outcome evaluation using feedback loops. |
| ACE Star Model of Knowledge Transformation | Describes five stages from knowledge discovery to practice integration and evaluation. |
| Johns Hopkins Nursing EBP Model | Uses the PET process (Practice question, Evidence, Translation) to rapidly integrate research into care delivery. |
| Stetler Model of EBP | Emphasizes clinician judgment and incorporates both internal data and external research evidence. |
Patient-Centered Care and Value-Based Purchasing
What is the Patient-Centered Medical Home (PCMH)?
The Patient-Centered Medical Home is a comprehensive primary care model designed to improve access, continuity, and coordination of care. It emphasizes long-term patient-provider relationships, team-based care, and active engagement of patients and families. The PCMH framework aligns care delivery with the goals of safety, equity, efficiency, and patient satisfaction while reducing fragmentation across healthcare settings (Agency for Healthcare Research and Quality, 2020).
What is Value-Based Purchasing (VBP), and what are its goals?
Value-Based Purchasing is a reimbursement strategy that ties provider payment to quality and performance outcomes rather than service volume. Under the Centers for Medicare & Medicaid Services (CMS), hospitals are evaluated across domains including patient safety, clinical effectiveness, efficiency, and patient experience. The overarching goal is to incentivize high-value care, improve outcomes, and reduce unnecessary costs.
What are Accountable Care Organizations (ACOs)?
Accountable Care Organizations consist of collaborative networks of providers who collectively assume responsibility for the quality and cost of care delivered to defined populations, particularly Medicare beneficiaries. ACOs operate under tiered participation models that define shared savings, risk exposure, and infrastructure requirements, including health information technology and quality reporting systems.
Transitional and Chronic Care Coordination
What is transitional care, and why is it important?
Transitional care refers to the coordination and continuity of healthcare during patient movement between settings, such as hospital discharge to home or skilled nursing facilities. Ineffective transitions increase the risk of medication errors, adverse events, readmissions, and patient dissatisfaction. Proactive planning, medication reconciliation, patient education, and interprofessional communication are essential components of safe transitions.
What is coordinated chronic care, and what models support it?
Chronic care coordination focuses on organizing services across providers and settings to meet the complex needs of individuals with long-term conditions. The Chronic Care Model (CCM) emphasizes six core elements: community resources, health system organization, self-management support, delivery system design, decision support, and clinical information systems. Together, these elements promote proactive, patient-centered management of chronic illness.
Lewin’s Change Theory and Its Application to Evidence-Based Practice
What are the stages of Lewin’s change theory?
Lewin’s Change Theory conceptualizes organizational change as a three-phase process. The unfreezing stage involves preparing individuals to accept change by challenging existing behaviors. The movement phase implements new practices or processes, while refreezing stabilizes changes by embedding them into routine operations. This model is frequently used in EBP initiatives to support adoption of new clinical guidelines and sustain practice improvements.
Domains of Wellness
| Domain | Description |
|---|---|
| Physical | Promoting bodily health through activity, nutrition, rest, and preventive care |
| Emotional | Supporting emotional regulation, stress management, and mental well-being |
| Spiritual | Fostering meaning, purpose, and alignment with personal values |
| Social | Encouraging healthy relationships and community engagement |
| Occupational | Achieving satisfaction, balance, and growth in work roles |
| Environmental | Maintaining safe, sustainable, and health-promoting surroundings |
Risks in Transitions of Care
Care transitions are high-risk periods due to fragmented communication and incomplete information transfer. Common adverse outcomes include overlooked diagnostic results, medication discrepancies, post-discharge infections, falls, and conflicting instructions from multiple providers. Addressing these risks requires standardized discharge planning and clear accountability.
Chronic Care Coordination Models
| Model | Description |
|---|---|
| Patient-Centered Medical Homes | Team-based care emphasizing coordination for chronic conditions |
| Self-Management Programs | Interventions that empower patients to manage symptoms and treatment |
| Home-Based Primary Care | Delivery of services in patients’ homes using in-person and virtual modalities |
| Distance Chronic Disease Programs | Telehealth-based management for rural or underserved populations |
Telemedicine: Synchronous vs. Asynchronous
| Type | Description | Examples |
|---|---|---|
| Synchronous | Real-time interaction between provider and patient | Videoconferencing, live remote exams |
| Asynchronous | Data collected and reviewed later | Store-and-forward imaging, biosignals |
Telemedicine expands access to care, improves continuity, and reduces geographic barriers, particularly in underserved regions.
Social Determinants of Health
Social determinants of health (SDOH) encompass economic stability, education, healthcare access, and community resources. The Expanded Chronic Care Model integrates these factors, recognizing their influence on disease prevention, health behaviors, and long-term outcomes.
National Initiatives to Improve Healthcare Quality
Major national initiatives include the National Notifiable Diseases Surveillance System, which supports public health monitoring, and Healthy People 2030, which establishes measurable objectives focused on health equity, prevention, and social determinants.
Disease Prevention Framework
| Level | Description |
|---|---|
| Primary Prevention | Preventing disease onset through risk reduction |
| Secondary Prevention | Early detection through screening |
| Tertiary Prevention | Managing disease to prevent complications |
Palliative Care
Palliative care prioritizes symptom management, pain relief, and psychosocial support for individuals with serious illness. It may be provided alongside curative treatment and focuses on quality of life for patients and families.
Epidemiologic Triad for Infectious Disease Causation
| Component | Description |
|---|---|
| Agent | Pathogenic organism |
| Host | Susceptible individual |
| Environment | Conditions facilitating transmission |
Disease occurs through dynamic interaction among these elements.
Current Screening Guidelines in Adults

Health Literacy, Disparities, and Culturally Responsive Care
Health literacy significantly influences patient engagement, adherence, and outcomes. Disparities arise when populations face systemic barriers to care, requiring culturally responsive interventions. Culturally responsive care acknowledges diverse beliefs, values, and health practices, fostering trust and improving care effectiveness.
