ABSTRACT
OBJECTIVE:
This enhanced recovery programme (ERP) aimed to achieve early recovery for patients undergoing major surgery. Results of a standardised ERP protocol for open infrarenal abdominal aortic aneurysm (AAA) repair within a hub and spoke regional network are presented.METHODS:
In this monocentric prospective study (January 2004 - December 2021), consecutive AAAs (≥ 55 mm) were included in the ERP (patient discharge on post-operative day [POD] 4). The four phases of the ERP were pre-admission, pre-operative, intra-operative, and post-operative. Exclusion criteria were BMI > 35 kg/m2, functional capacity < 4 MET, previous aortic or abdominal surgery, and life expectancy < 5 years. Transperitoneal surgery was undertaken with routine AAA resection, graft interposition, and closure.RESULTS:
Consecutive patients (n = 778) were enrolled into the study (mean age 72.3 ± 3.2 years; n = 712 men); 160 (20.5%) were treated in spoke hospitals. Median follow up was 78 (IQR 28, 128) months; median length of stay, procedure time, and blood loss were 4 days (IQR 3, 5), 190 min (IQR 170, 225), and 564 mL (IQR 300, 600). Infrarenal clamping and tube graft configuration were used in 96.5% (n = 751) and 72.5% (n = 564) of patients; 30 day mortality and complication rates were 0.4% (n = 3) and 9.2% (n = 72). Discharge after POD 4 occurred in 15.0%, and most significant predictors for discharge after POD 4 were haemotransfusion, re-intervention, and ileus over 3 days. Overall survival was 98.2% at 1 year, 85.0% at 5 years, and 59.9% at 10 years. Freedom from re-intervention was 97.9% at 1 year, 94.1% at 5 years, and 86.8% at 10 years. Short and long term outcomes were comparable between hub and spoke hospitals.CONCLUSION:
The ERP protocol was associated with low short and long term mortality and complication rates. Future studies should apply the ERP protocol to other vascular centres.
