Clinical outcomes and cost analysis of a "fast track" postoperative care pathway for ileal pouch-anal anastomosis. A case control study

PURPOSE: Traditional length of hospital stay after ileal pouch-anal anastomosis is 8 to 15 days. Fast track rehabilitation programs reduce stay, but there are concerns that readmission and complication rates may be increased. This study evaluated a fast track pathway after ileoanal pouch surgery. METHODS: One hundred three consecutive patients underwent ileal pouch-anal anastomosis on two colorectal services using a fast track protocol with early ambulation, diet, and defined discharge criteria. Direct hospital costs and 30-day and long-term complication data were collected. Patients were matched to controls managed with traditional care pathways by other colorectal staff. RESULTS: Matching was established for 97 patients. Fast track patients had shorter hospital stay than controls (median 4 vs. 5 days; mean 5.0 vs. 5.9, P=0.012). Readmission and recurrent operation rates were similar (24 vs. 20 percent, P=0.49, and 9 vs. 10 percent, P=0.8, fast track vs. control, respectively). Median direct costs per patient (US$) within 30 days were lower with fast track (5692 vs. 6672, P=0.001), primarily because of reductions in postoperative management expenses. Complication rates, including pouch failure, bowel obstruction, pouchitis, and anastomotic stricture were comparable. Early discharge (:55 days from surgery) occurred in 79 (77 percent) fast track patients. Failure with early discharge was associated with male gender, reoperations, and anastomotic complications. CONCLUSIONS: Fast track protocol after ileoanal pouch surgery reduces length of stay and hospital costs without increasing complication rates. Successful early discharge usually signals a benign postoperative course.
