Background:
A surgical acute care unit (SACU) is designed to provide level 1 care for surgical patients. The aim of the present study was to audit the effects of the introduction of a SACU in a teaching hospital surgical department.
Methods:
A retrospective case-note audit of all admissions to the newly established SACU over the first 6 months was performed. Expected mortality and morbidity was calculated using POSSUM (physiological and operative severity score for the enumeration of mortality and morbidity) scores. Critical care data for the same period and the 6 months prior to the SACU opening was examined to determine any effect on critical care workload.
Results:
The SACU admitted 131 patients during the audit period. There was no significant difference between predicted and observed mortality or morbidity. There was no effect on critical care length of stay after the SACU opened. Many patients who would have needed critical care beds before the SACU opened were admitted directly to the SACU after it opened.
Conclusions:
This audit demonstrates that the provision of a surgical acute care unit allows many patients who would normally need to be admitted to the critical care unit for postoperative care to be safely admitted to level 1 care beds.
