Understanding the Acute Frailty Unit Model
An acute frailty unit (AFU) is a modern approach to geriatric care, centralizing the care of older, frail patients who might otherwise be spread across different hospital wards. The goal is to provide a quick, comprehensive geriatric assessment (CGA) and a personalized plan for rapid discharge, often within 48 to 72 hours. This model acknowledges that standard hospital settings can negatively affect frail individuals, potentially leading to increased risks like delirium, falls, and a decline in function.
The Need for a Specialized Approach
Traditional hospitals may not be ideally suited for older adults with frailty, where factors like reduced mobility and the risk of infection can significantly impact their health. AFUs counter this by offering a calm, age-friendly environment where a specialized multidisciplinary team can address the specific challenges of frailty. This team can quickly identify issues such as managing multiple medications or cognitive problems that could be overlooked in a general ward.
Key Components and the Multidisciplinary Team
The effectiveness of an AFU relies on its team-based model, led by experts in geriatric medicine. This multidisciplinary team (MDT) works collaboratively, providing comprehensive and patient-focused care. A typical AFU MDT includes:
- Geriatrician: A doctor who specializes in older adult care and directs the medical treatment.
- Nurses and Healthcare Assistants: Provide daily care, monitoring, and help with activities.
- Occupational Therapists (OT): Evaluate and assist patients in regaining abilities for daily living.
- Physiotherapists (PT): Create exercise plans to improve strength and mobility.
- Pharmacists: Review medications to ensure they are appropriate and to manage polypharmacy.
- Social Workers: Address social issues and assist with discharge planning and necessary support.
This integrated approach ensures all aspects of a patient's health and social needs are addressed from the start.
The Patient Journey through an Acute Frailty Unit
The patient's experience in an AFU is designed for efficiency and a safe return home. The process typically involves:
- Early Identification: Patients are often referred directly from the emergency department or an acute medical unit after being identified as frail using screening tools like the Clinical Frailty Scale.
- Rapid Assessment: A CGA is performed quickly upon arrival, assessing not just the immediate health problem but also overall health, function, cognition, medications, and social support.
- Holistic Treatment Plan: The MDT develops a plan based on the CGA, addressing the acute issue and underlying frailty, which might include adjusting medication or starting rehabilitation early.
- Proactive Discharge Planning: Planning for a safe discharge begins immediately, involving discussions with the patient and family to ensure necessary support is arranged for home or community care.
- Discharge or Transfer: The aim is for discharge within 48–72 hours, either home with support, to a rehabilitation facility, or, if needed, to a longer-stay geriatric ward.
Comparison: Acute Frailty Unit vs. General Medical Ward
Comparing AFUs to general medical wards highlights their specialized benefits:
| Feature | Acute Frailty Unit (AFU) | General Medical Ward |
|---|---|---|
| Focus of Care | Holistic care focused on frailty, function, and discharge planning. | Care centered on the immediate medical problem. |
| Environment | Quieter, age-friendly to reduce hospital risks. | Often busy and less optimized for older adults. |
| Multidisciplinary Team (MDT) | Geriatrician-led integrated team from admission. | MDT input may be through consultations, potentially causing delays. |
| Length of Stay | Aims for short stays (48–72 hours) to minimize decline. | Can result in longer stays for complex elderly patients. |
| Discharge Planning | Begins early and involves proactive communication. | Often reactive and may start later in the admission. |
| Outcomes for Frail Patients | Linked to better outcomes, including lower mortality and fewer readmissions. | Can lead to worse functional outcomes and higher readmission rates for frail patients. |
Long-Term Benefits and Outcomes
Studies show that models similar to AFUs, like Acute Care for Elders (ACE) units, result in reduced functional disability, lower rates of nursing home admission, and decreased hospitalization costs. Research on CGA units indicates lower mortality and fewer readmissions at three months. By prioritizing prevention and early action, AFUs help older adults maintain their independence and quality of life, benefiting patients, families, and improving hospital resource use.

The Role of Family and Carers
Family members and unpaid carers are key partners in AFU care. The MDT involves them from the start in assessments and discharge planning. Understanding the patient's usual function, social support, and wishes is vital for a smooth transition home. Support for caregivers is also provided, connecting them with community services and education to help manage care at home. Programs such as the National Family Caregiver Support Program offer assistance to families caring for loved ones at home.
The Future of Frailty Care
The success of AFUs is influencing broader changes in healthcare for older adults. The core principles of AFUs—early assessment, person-centered care, and coordinated discharge planning—are being applied in other settings like emergency departments and home-based care. This highlights the growing understanding that effective frailty care needs a proactive, comprehensive, and team-oriented approach. As the population ages, the AFU model offers a strong foundation for providing high-quality care that supports long-term independence and well-being. An AFU represents a philosophy of care focused on the unique needs of frail older adults to restore their health and quality of life, and it is becoming a crucial part of modern geriatric medicine.
Conclusion
An acute frailty unit (AFU) is a specialized hospital service providing rapid, multidisciplinary care for frail older adults. Focusing on comprehensive assessment and planning for discharge, AFUs have shown better outcomes for patients compared to standard hospital care. This approach is a significant step forward in geriatric medicine.
