The Results of the AMU
Generally 30-40% of patients will be discharged directly after the initial assessment, stabilisation and treatment.  This will normally take up to 8 hours unlike the Emergency Department which is 4 hours.  The remaining 60-70% will require admission to hospital for further treatment and stabilisation.  

After an overnight stay a further 10-20% will be discharged (Day 1).  The remaining 50-60% will require at least one further night in hospital. After a further overnight stay another 10-20% will be discharged (Day 2).  

The remaining 40-50% will require an extended stay in hospital.  Therefore the Acute Medical team is able to manage 50-60% of patients who present to hospital with an acutely medical condition within 48 hours.
