Understanding Staph Infections in Seniors: Causes & Risk Factors

Older adults face elevated staph infection risk due to:

1. Immune senescence: Weaker innate and adaptive immunity
2. Chronic diseases: Diabetes, CKD, COPD, vascular disease impair defenses
3. Skin changes: Thinning, dryness, reduced barrier function
4. Healthcare exposure: Hospitals, long-term care harbor resistant strains
5. Hygiene challenges: Mobility/cognitive limits impede self-care
6. Impaired wound healing: Delayed closure → bacterial entry
7. Malnutrition: Protein/calorie deficits weaken immunity
8. Polypharmacy: Antibiotics, steroids, PPIs alter microbiome
9. Communal living: Close quarters, shared facilities in LTCFs

Prevention

• Skin care: moisturize, protect from trauma
• Hand hygiene for patient and caregivers
• Prompt wound care
• Vaccinations (pneumococcal, flu)
• Nutritional optimization
• Antibiotic stewardship

Early recognition and treatment are critical—seniors deteriorate faster.
