Acute Surgical Unit: a new model of care.

The traditional on-call system for the management of acute general surgical admissions is inefficient and outdated. A new model, Acute Surgical Unit (ASU), was developed at Nepean Hospital in 2006. The ASU is a consultant-driven, independent unit that manages all acute general surgical admissions. The team has the same make up 7 days a week and functions the same every day, including weekends and public holidays. The consultant does a 24-h period of on-call, from 7 pm to 7 pm. They are on remote call from 7 pm to 7 am and are in the hospital from 7 am to 7 pm with their sole responsibility being to the ASU. The ASU has a day team with two registrars, two residents and a nurse practitioner. All patients are admitted and stay in the ASU until discharge or transfer to other units. Handover of the patients at the end of each day is facilitated by a comprehensive ASU database. The implementation of the ASU at Nepean Hospital has improved the timing of assessment by the surgical unit. There has been significant improvement in the timing of operative management, with an increased number and proportion of cases being done during daylight hours, with an associated reduction in the proportion of cases performed afterhours. There is greater trainee supervision with regard to patient assessment, management and operative procedures. There has been an improvement in the consultants' work conditions. The ASU provides an excellent training opportunity for surgical trainees, residents and interns in the assessment and management of acute surgical conditions.
