Acute Admissions Unit (AAU)

Your 24/7 hospital admission service

The Acute Admissions Unit (AAU) at Cromwell Hospital provides fast, frictionless access for acutely unwell patients to be assessed and admitted to a dedicated secondary care centre. Operating 24/7, our service provides access for clinicians to refer both UK-based and international patients age 18 and over into a consultant-led service.  

Led by a Consultant Acute Physician with support from a dedicated onsite multidisciplinary team, our Acute Admissions Unit has immediate access to consultant-led specialties, including cardiology, orthopaedics, general surgery, and gynaecology to support a seamless patient journey. 

Once assessed, our integrated service will ensure your patient's care is managed by the most appropriate specialist consultant team, all under one roof at Cromwell Hospital. 

Please note, this is a referral-only service and we do not accept self-referrals from patients.

The Acute Admissions Unit is referral-only service for adult patients with serious but non-life-threatening illness. We accept referrals from clinicians on behalf of private patients, consultants, embassies, or corporate clients.  

We do not accept self-referrals from patients. If you are a patient and think you require admission, you can access our private GP services or Urgent Care Centre at Cromwell Hospital.  

How to refer a patient 

  1. Contact the Clinical Site Manager on 020 7341 5032 to discuss your proposed admission to the AAU. They will complete a referral form with you on the phone. Alternatively, use the 'Refer a patient' form below and a member of the team will be in touch.
  2. If your patient meets the criteria for admission, they will receive an admission time for the unit. If required, we can support with transportation via private ambulance from a clinician-led service. 
  3. Once the patient arrives, they will be admitted to our dedicated admissions unit for immediate assessment by a nurse. The patient will then be assessed by a doctor within 30 minutes. 
  4. If necessary, we will carry out further diagnostics and tests. A treatment plan will be arranged in conjunction with the consultant of the day. 
  5. We will contact you at each step of the patient's pathway, keeping you informed of their diagnosis and treatment plan.
