What an Acute Geriatric Unit Does
An acute geriatric unit (AGU) is a specialized inpatient hospital ward designed to prevent functional decline and loss of independence in elderly patients during acute medical illness, using comprehensive geriatric assessment and an interdisciplinary team approach to maintain self-care abilities from admission through discharge. 1
Core Functions
Prevention of Hospital-Associated Disability
- The primary target is preventing the development or worsening of functional decline that commonly occurs when elderly patients are hospitalized for acute illness 1, 2
- This includes specific prevention of geriatric syndromes: delirium, pressure ulcers (decubitus wounds), incontinence, and immobility 3
- The unit employs nurse-initiated guidelines and nonpharmacologic interventions to restore independent functioning lost due to acute illness 2
Comprehensive Geriatric Assessment
- A multidisciplinary team completes structured geriatric assessment integrating medical, functional, cognitive, and social domains 1
- The team typically includes geriatricians, specialized nurses, physiatrists, social workers, and pharmacists working in coordinated fashion 3, 4
- Assessment is tailored to each patient's individual needs rather than applying generic protocols 2
Prepared Environment for Safe Self-Care
- The physical environment is specifically designed to encourage safe patient independence 1, 2
- This includes modifications like reclining chairs and pressure-redistributing foam mattresses 5
- Standards of care reduce iatrogenic illness from polypharmacy, physical restraints, and unnecessary diagnostic procedures 2
Clinical Outcomes
Demonstrated Benefits
- Randomized clinical trials show reduced functional disability among patients treated in ACE units 1
- Reduced risk of nursing home placement after discharge 1
- Lower hospitalization costs compared to standard medical wards 1
- High discharge-to-home rates (approximately 79%) with low nursing home placement rates (7.3% excluding those already in nursing homes) 6
- Shortened hospital length of stay (average 11.5 days in early studies) 6
Transitions of Care Planning
- Early discharge planning begins at admission, coordinated with patients and families 1, 3
- Collaboration with home health services and home-safety assessments 5
- Large-font discharge instructions and appropriate follow-up arrangements 5
Educational and Research Functions
- The unit serves as a training site for medical students, residents, and geriatrics fellows to learn fundamentals of geriatric medicine 4, 6
- Provides a platform for research in improving care of hospitalized frail elderly 4
- Staff education includes geriatric-specific modules and continuing medical education 5
Key Distinction
The AGU differs from standard medical wards by bringing specialized geriatric expertise directly to acutely ill elderly patients in a geographically based unit, rather than scattering these patients across general medical floors where their unique needs may not be adequately addressed. 4 This concentrated approach allows efficient coordination of multiple disciplines needed for complex geriatric care 4
