Long-term outcomes of an integrated transfusion reduction initiative in patients undergoing resection for colorectal cancer.

Background: Perioperative blood transfusion in patients with colorectal cancer has been associated with increased cost, morbidity, mortality, and decreased survival. Five years ago, a transfusion reduction initiative (TRI) was implemented. We sought to evaluate the 5-year effectiveness and patient outcomes before and after the TRI.

Methods: Patients who underwent colorectal resection for adenocarcinomas before (January 2006 to October 2009) and after the TRI (November 2009 to December 2013) were reviewed.

Results: A total of 484 patients were included; 267 and 217 patients were in the pre- and post-TRI groups, respectively. Decreased overall transfusion rates were sustained throughout the entire post-TRI era (17% vs 28%, P = .006). Three-year colorectal cancer disease-free survival rates were similar in the pre- and post-TRI eras at 85.3% (95% confidence interval [CI]: 79.9 to 89.3) and 81.6% (95% CI: 71.9 to 88.2), respectively. Three-year disease-free survival rate was lower in those receiving BTs vs those without BTs at 78.4% (95% CI: 65.7 to 86.8) vs 85.3% (95% CI: 80.4 to 89.1), respectively.

Conclusions: A TRI remains a safe, effective way to reduce blood utilization in colorectal cancer surgery.
