The provision of acute surgical care in the public sector is becoming increasingly difficult because of limitation of resources and the unpredictability of access to theatres during the working day. An acute-care surgical service was developed at the Prince of Wales Hospital to provide acute surgery in a more timely and efficient manner. A roster of eight general surgeons provided on-site service from 08.00 to 18.00 hours Monday to Friday and on-call service in after-hours for a 79-week period. An acute-care ward of four beds and an operating theatre were placed under the control of the rostered acute-care surgeon (ACS). At the end of each ACS roster period all patients whose treatment was undefined or incomplete were handed over to the next rostered ACS. Patient data and theatre utilization data were prospectively collected and compared to the preceding 52-week period. Emergency theatre utilization during the day increased from 57 to 69%. There was a 11% reduction in acute-care operating after hours and 26% fewer emergency cases were handled between midnight and 08.00 hours. There was more efficient use of the entire theatre block, suggesting a significant cultural change. Staff satisfaction was high. On-site consultant-driven surgical leadership has provided significant positive change to the provision of acute surgical care in our institution. The paradigm shift in acute surgical care has improved patient and theatre management and stimulated a cultural change of efficiency.

Not all high-risk features have similar adverse effects on OS. T4 tumors and their combination with other HRF achieve the most survival benefit with adjuvant therapy. Type and number of high-risk features should be taken into consideration when recommending adjuvant chemotherapy in stage II colon cancer.

Although adequate lymph node retrieval is more likely in hospitals with a recognized cancer program, survival outcome is associated with the lymph node count rather than with cancer program classification. Less than half of the cases reviewed in this study met the minimum lymph node-count guideline, indicating the need for process improvement for all hospitals.
