Chronic diseases — heart disease, stroke, cancer, diabetes, chronic lung disease, chronic kidney disease, and obesity — are the leading causes of death, disability, and health care spending in the United States. Most share a small set of modifiable risk factors: tobacco use, poor nutrition, physical inactivity, and excessive alcohol use.
Goals of community chronic disease programs: prevent disease through risk-factor reduction; find disease early through screening; keep it controlled through continuous management and self-management; and so prevent complications, disability, and premature death while improving quality of life.
| Level | Chronic disease example | Rehabilitation example |
|---|
| Primary | Tobacco prevention, healthy food access, safe places for activity, the lifestyle change programs for prediabetes | Injury prevention (helmets, fall prevention) |
| Secondary | Blood pressure, diabetes, cancer screening; follow-up of abnormal results | Early detection of developmental delay or post-stroke depression |
| Tertiary | Disease control, cardiac and pulmonary rehabilitation, prevention of complications | Restoring function and participation after stroke, amputation, spinal cord injury |
Disability and rehabilitation
- Disability results from the interaction between a person's health condition and barriers in the environment, not from the condition alone.
- Rehabilitation aims to maximize remaining function, remove barriers, and enable an independent, satisfying life in the community.
- Community-based rehabilitation (CBR) delivers rehabilitation where people live, uses local resources, and involves people with disabilities, families, and communities as active partners — rather than relying only on hospitals and institutions.
The ICF model (WHO International Classification of Functioning, Disability and Health)
| Component | Meaning | Example after stroke |
|---|
| Body functions and structures | Physiologic and anatomic parts; problems = impairments | Right-sided weakness, aphasia |
| Activities | Tasks a person does; problems = activity limitations | Cannot dress or walk independently |
| Participation | Involvement in life situations; problems = participation restrictions | Cannot return to work or church |
| Environmental factors | Physical, social, and attitudinal surroundings and policies — can be barriers or facilitators | Home with steps and a narrow bathroom, family support, transportation, disability benefits |
| Personal factors | Age, coping style, education, motivation | Strong motivation to go home |
The ICF describes how a health condition affects functioning and participation; it does not classify causes or pathology.
Chronic Care Model — better outcomes come from productive interactions between an informed, activated client and a prepared, proactive team, supported by: community resources and policies, the health system, self-management support, delivery system design (team roles, planned visits, follow-up), decision support (evidence-based guidelines), and clinical information systems (registries).
Self-management support helps clients build the knowledge, skills, and confidence (self-efficacy) to manage their condition day to day — monitoring symptoms, taking medications, making lifestyle changes, solving problems, and deciding when to seek help. Tools include goal setting and action planning, motivational interviewing, and group programs such as the Chronic Disease Self-Management Program.
Registry-based management — a disease registry lists every client with a condition so the team can track, recall, and follow up systematically. Core elements: case identification and registration, standardized assessment and care protocols, regular follow-up and recall of clients overdue for care, accurate records, and linkage with other services. Free medication supply is not a required element.
US screening and prevention anchors
| Topic | Current US recommendation |
|---|
| Blood pressure | Screen adults 18 and older (USPSTF). Categories (AHA/ACC, 2025 update keeps the 2017 categories): normal < 120/80; elevated 120–129/< 80; stage 1 130–139 or 80–89; stage 2 ≥ 140 or ≥ 90 mm Hg |
| Prediabetes and type 2 diabetes | USPSTF: screen adults 35–70 with overweight or obesity. Tests: fasting plasma glucose, A1C, or 75-g oral glucose tolerance test. Diabetes: A1C ≥ 6.5%, FPG ≥ 126 mg/dL (7.0 mmol/L), 2-hour OGTT ≥ 200 mg/dL (11.1 mmol/L). Prediabetes: A1C 5.7–6.4%, FPG 100–125 mg/dL (5.6–6.9 mmol/L) |
| Diabetes prevention | National Diabetes Prevention Program: a year-long lifestyle change program aiming for 5–7% weight loss and 150 minutes of activity per week; the original trial cut progression to type 2 diabetes by 58% |
| Colorectal cancer | USPSTF: screen adults 45–75 (stool-based tests or direct visualization); ages 76–85 selectively |
| Lung cancer | USPSTF 2021: annual low-dose CT for adults 50–80 with a 20 pack-year history who smoke now or quit within 15 years |
| Breast cancer | Mammography every 2 years, ages 40–74 (USPSTF 2024) |
Community rehabilitation principles
- Services in the community, close to home; integration, not segregation.
- Participation and empowerment of people with disabilities in decisions about their own lives and programs ("nothing about us without us").
- Interprofessional team: rehabilitation physician, nurse, physical, occupational, and speech therapists, social worker, psychologist, and vocational counselor, with the client and family at the center.
- Environmental modification: remove barriers at home and in the community.
- Peer support: people with lived experience of disability give information, role modeling, and emotional support that builds self-help and empowerment.
- Personal assistance services support people with disabilities in daily and social activities (bathing, dressing, household tasks, getting to work) so they can live independently.
US legal framework for disability: the Americans with Disabilities Act (ADA, 1990) prohibits discrimination and requires reasonable accommodation and accessibility. In Olmstead v. L.C. (1999) the Supreme Court held that unnecessary segregation of people with disabilities in institutions is discrimination, so states must offer services in the most integrated setting appropriate — a driver of Medicaid home and community-based services.
Chronic disease programs
- Hypertension: teach that hypertension is usually silent, so medication must continue even when the client feels well; home blood pressure monitoring; DASH-style eating, sodium reduction, weight loss, activity, and limiting alcohol.
- Diabetes: screening events linked to confirmatory testing and follow-up; self-management education (glucose monitoring, foot care, medication, hypoglycemia recognition).
- Obesity: individualized counseling that fits the person's environment, motivation, and preferences, with gradual changes in eating and activity — not one-size-fits-all crash diets.
- COPD: pulmonary rehabilitation (exercise training, breathing techniques, education) to reduce dyspnea and improve function and quality of life; smoking cessation.
- Heart failure home visits: teach daily weights and symptom reporting. Refer urgently for sudden or worsening shortness of breath, orthopnea or paroxysmal nocturnal dyspnea, chest pain, confusion, or rapid weight gain (2–3 lb (about 1 kg) in a day or 5 lb (about 2 kg) in a week).
- Population level: smoke-free policies, healthy food in schools and worksites, safe walking routes, community gardens.
Community rehabilitation
- Assess using the ICF: impairments, activities, participation, environment, personal factors.
- Home modification: remove door thresholds and loose rugs, add grab bars and handrails, ramps, raised toilet seats, shower chairs, good lighting, and move essential items within reach.
- Stroke family teaching: the top priority is safety and fall prevention at home (supervised transfers, clear pathways, call system), plus swallowing precautions, skin care, and emotional support.
- Connect clients to peer counseling, vocational rehabilitation, accessible transportation, assistive technology, and caregiver respite.
- Empowerment: respect self-determination; involve the client in goal setting; teach how to find and use resources and self-advocate.
- Screener and case finder: organizes community screening and ensures abnormal results lead to diagnosis and care.
- Educator and coach: builds self-management skills and self-efficacy using teach-back and motivational interviewing.
- Case manager: maintains registries, recalls clients who miss follow-up, coordinates services.
- Rehabilitation nurse: prevents secondary complications (falls, pressure injuries, contractures, depression), promotes independence in ADLs, and teaches families.
- Advocate: for accessibility, accommodations, and community-based services.
- Program planner and evaluator: sets measurable objectives (for example, percentage of registered hypertensive clients with controlled blood pressure).
- Team collaborator with therapists, social workers, pharmacists, and community partners; pharmacists join when medication management is complex.
- ADA: people with disabilities have the right to accessible services and reasonable accommodations; clinics must be accessible and communication must be effective (interpreters, including sign language, and accessible materials).
- Olmstead integration mandate: support community living rather than institutional placement when appropriate and desired.
- Autonomy and dignity of risk: clients with chronic illness or disability make their own choices; avoid paternalism.
- Confidentiality of registry data (HIPAA); use data only for care and public health purposes.
- Justice: prevention resources should reach groups with the greatest burden.
- Documentation of screening follow-up, teaching, and referrals.
Case 1 — Stroke at home. A client returns home with right hemiparesis. His wife asks what matters most. Correct teaching: fall prevention and home safety first — safe transfers, clear pathways, grab bars, supervision when walking. Why: falls cause new injury and set back rehabilitation.
Case 2 — ICF environmental factor. While planning rehabilitation for a client with hemiplegia, the nurse notes steps at the entrance and a bathroom too narrow for a walker. Correct classification: environmental factors (physical environment). Why: the ICF includes housing, transportation, social support, and policies as environmental factors.
Case 3 — Heart failure visit. A client says she now sleeps on three pillows and woke up gasping last night; her weight rose 2.5 kg (5.5 lb) this week. Correct action: arrange same-day medical evaluation. Why: orthopnea, paroxysmal nocturnal dyspnea, and rapid weight gain signal worsening heart failure and possible pulmonary edema.
Case 4 — Self-management. A client with diabetes asks the nurse to "just tell me what to do." Correct approach: build his knowledge and skills, set a small goal with him, and support his confidence to decide day to day. Why: self-management support aims at the client's own capability, not dependence on the nurse.
- Thinking screening alone is the goal — screening without follow-up and continuous management does not reduce complications.
- Saying hypertension teaching should focus on symptoms — it is usually asymptomatic.
- Treating ICF as a classification of disease causes — it describes functioning, disability, and context.
- Describing CBR as institution-centered — it is community-centered and participatory.
- Ignoring environmental barriers and focusing only on impairment.
- Assuming A1C cannot be used for screening — in the US, FPG, A1C, and OGTT are all accepted.
- Doing everything for the client instead of promoting independence.
- Chronic disease program goals: prevention, early detection, continuous management and self-management → fewer complications and deaths
- Self-management support = knowledge, skills, confidence for daily decisions
- Registry elements: registration, standardized care, recall and follow-up, records, linkage
- Hypertension teaching: silent disease → continue medication, lifestyle change; stage 1 = 130–139 or 80–89
- USPSTF diabetes screening 35–70 with overweight or obesity; A1C ≥ 6.5%, FPG ≥ 126 mg/dL (7.0 mmol/L)
- National DPP: 5–7% weight loss, 150 min/week activity, 58% risk reduction
- Pulmonary rehab: less dyspnea, better function and quality of life
- HF red flags: worsening dyspnea, orthopnea, weight gain 2–3 lb/day or 5 lb/week
- ICF: body functions/structures, activities, participation, environmental and personal factors
- CBR: community-based, participatory, empowerment, peer counseling
- Home modification: remove thresholds, grab bars and rails
- ADA and Olmstead: accessibility and most integrated setting
