12.2 Disease Prevention & Screenings
Key Takeaways
- III-A-2 covers disease prevention for the individual, family, and community—including screenings and education
- Primary, secondary, and tertiary prevention map cleanly to exam vignettes: stop disease, detect early, limit disability
- USPSTF A/B recommendations commonly tested for older adults include colorectal cancer screening, osteoporosis screening in women ≥65, AAA once in men 65–75 who ever smoked, and fall-prevention exercise referral for those at increased risk
- Screening decisions after age ~75–85 increasingly require life expectancy, prior screening history, comorbidity, and patient goals—not automatic annual everything
- Prevention education must reach family/caregivers and community settings (clinics, senior centers, congregate living), not only the bedside patient
Disease Prevention & Screenings
Quick Answer: GERO-BC III-A-2 tests disease prevention within the individual, family, and community, with examples that include screenings and education. Know prevention levels (primary/secondary/tertiary), high-yield USPSTF screens for older adults, and when to individualize or stop screening based on life expectancy, prior history, and goals of care.
Prevention is not a soft “wellness add-on” on this exam—it is core Professional Foundation knowledge. Gerontological nurses reduce morbidity by combining risk reduction, early detection, and disability limitation, then teaching those strategies to patients, families, and community partners.
Prevention Levels (Must-Know Map)
| Level | Definition | Older-adult examples |
|---|---|---|
| Primary | Prevent disease or injury before it occurs | Immunizations; smoking cessation; exercise to prevent falls; nutrition counseling; home hazard reduction; blood-pressure lifestyle measures before hypertension complications |
| Secondary | Detect disease early / interrupt progression | Cancer screenings; BP/lipid checks; depression and cognitive screens; A1C monitoring in at-risk adults; AAA ultrasound in indicated men |
| Tertiary | Limit disability and complications of established disease | Cardiac rehab after MI; foot care education in diabetes; pressure-injury prevention in immobility; pulmonary rehab in COPD; caregiver training after stroke |
Exam tip: If the stem already has established disease and the goal is “prevent complications / restore function,” choose tertiary. If the person is asymptomatic and you are looking for hidden disease, choose secondary. If you are preventing the condition itself, choose primary.
Individual, Family, and Community—Why the TCO Says All Three
Prevention fails when it stops at the patient alone.
| Level | What “counts” as prevention work |
|---|---|
| Individual | Age-appropriate screens, vaccine review, fall risk counseling, tobacco/alcohol counseling, medication review to prevent iatrogenic harm |
| Family / caregiver | Teach early warning signs (CHF weight gain, UTI confusion), safe transfer techniques, medication organization, when to call; support caregiver health to prevent neglect and burnout |
| Community | Flu clinics, fall-prevention classes, senior-center BP checks, health fairs, congregate-meal nutrition programs, outreach to homebound elders |
On vignettes, the “best next step” may be arranging a community resource or caregiver education—not another hospital test.
High-Yield Screenings for Older Adults (USPSTF-Oriented)
USPSTF grades guide many GERO-BC–style items. Memorize the population + action, and remember grades A/B are generally offered; C is selective; D is recommend against; I is insufficient evidence.
Cancer and vascular screens commonly tested
| Condition | Typical recommendation pattern for older adults | Nurse focus |
|---|---|---|
| Colorectal cancer | Screen adults 45–75 (A for 50–75; B for 45–49). Ages 76–85: selectively offer (C) based on health, prior screening, preferences. Generally stop after 85 | Confirm modality (colonoscopy, FIT, etc.), follow-up of positive FIT, document shared decisions in late old age |
| Breast cancer | Biennial mammography recommended for women 40–74 (current USPSTF). Age ≥75: individualize; evidence less clear | Discuss comorbidity, prior screening, life expectancy, and patient values |
| Lung cancer | Annual low-dose CT for adults 50–80 with sufficient smoking history who currently smoke or quit within 15 years | Pair with cessation counseling; stop when life expectancy limited or unwilling to treat findings |
| Cervical cancer | Usually stop after 65 if adequate prior negative screening and no high-risk factors | Do not restart routine Pap solely because of age in low-risk, adequately screened women |
| AAA | One-time ultrasound in men 65–75 who have ever smoked (B) | Identify smoking history; arrange ultrasound; counsel on smoking cessation |
Bone, fall, and metabolic prevention screens
| Topic | Evidence-based action |
|---|---|
| Osteoporosis | Screen women ≥65 with bone measurement testing; screen postmenopausal women <65 at increased risk |
| Falls | For community-dwelling older adults at increased fall risk, refer to exercise interventions; multifactorial interventions may be individualized |
| Hypertension / diabetes complications | Periodic BP measurement; diabetes screening/monitoring per risk; eye/foot screens once diabetes established (secondary/tertiary overlap) |
| Depression | Screen adults, including older adults, when systems exist for diagnosis and follow-up |
| Cognitive impairment | Formal USPSTF screening of asymptomatic community adults remains nuanced; still assess cognition when clinically indicated (function decline, safety concerns, caregiver report) |
When to Individualize or Stop Screening
Blind annual “everything” is not gerontological best practice. Decision factors:
- Life expectancy and lag time to benefit — screening that takes 7–10 years to show mortality benefit helps less if prognosis is short.
- Prior screening history — a recently negative high-quality colonoscopy changes the calculus for ages 76–85.
- Competing morbidity — advanced dementia, end-stage disease, or severe frailty may make detection without treatable benefit harmful.
- Patient goals — some prefer comfort-focused plans; others want every available early-detection option.
- Harms — false positives, invasive follow-up, overdiagnosis, and treatment burden.
Document the shared decision. On exam items, the best answer often includes discuss benefits/harms and patient preferences rather than ordering a default invasive test in a frail 88-year-old with limited life expectancy.
Education as Prevention (Explicit TCO Example)
Education is listed alongside screenings under III-A-2. Effective prevention teaching is:
- Risk-specific — “Call if weight rises 2–3 lb overnight,” not vague “watch your heart.”
- Actionable — who to call, what to do in the first 24 hours.
- Literacy- and sensory-adapted — large print, teach-back, interpreter, hearing amplifiers.
- Family-inclusive — especially when cognition or IADL dependence is present.
- Reinforced across settings — discharge, clinic, home health, senior housing.
Prevention education priorities by common risk
| Risk | Core teaching points |
|---|---|
| Falls | Home hazards, strength/balance exercise, vision, meds that sedate, proper footwear, assistive devices |
| Infection | Hand hygiene, vaccine access, early symptom reporting (atypical presentations: confusion, falls) |
| Cardiovascular | BP self-monitoring if appropriate, sodium awareness, activity pacing, smoking cessation |
| Cancer prevention | Tobacco cessation, UV protection, screening adherence, symptom red flags |
| Medication harm | Pillbox use, Beers-related counseling, no sharing meds, bring all bottles to visits |
Putting It Together: A Prevention Visit Checklist
For a community-dwelling 72-year-old, a GERO-BC–aligned prevention approach might include:
- Update problem list and goals of care briefly.
- Review USPSTF-indicated screens due (CRC, mammogram if applicable, osteoporosis if due, AAA if eligible).
- Review immunizations (covered in the next section) and lifestyle risks.
- Screen fall risk, depression, and caregiver strain as indicated.
- Provide education and community referrals (exercise class, smoking cessation, nutrition program).
- Document shared decisions for any deferred screens.
Prevention on this exam is judgment plus systems thinking—not a memorized flyer.
Teaching safe transfer techniques to a family caregiver after a patient’s stroke to prevent future injury and complications is best classified as which prevention level?
