BackgroundThe hemoglobin threshold for transfusion of red blood cells in patients with acute gastrointestinal (GI) bleeding is controversial. We compared the efficacy and safety of a restrictive transfusion strategy with those of a liberal transfusion strategy.MethodsObjectiveThe objective was to prove that the restrictive threshold for red blood cell transfusion in patients with acute upper GI bleeding (UGIB) was safer and more effective than a liberal transfusion strategy.ResultsIn total, 225 patients assigned to the restrictive strategy (51%) and 65 assigned to the liberal strategy (15%) did not receive transfusions (P <0.001). The probability of survival at 6 weeks was higher in the restrictive-strategy group than in the liberal-strategy group (95% versus 91%; hazard ratio (HR) for death with restrictive strategy, 0.55; 95% confidence interval (CI) 0.33 to 0.92; P = 0.02). Further bleeding occurred in 10% of the patients in the restrictive-strategy group and in 16% of the patients in the liberal-strategy group (P = 0.01), and adverse events occurred in 40% and 48%, respectively (P = 0.02). The probability of survival was slightly higher with the restrictive strategy than with the liberal strategy in the subgroup of patients who had bleeding associated with a peptic ulcer (HR 0.70, 95% CI 0.26 to 1.25) and was significantly higher in the subgroup of patients with cirrhosis and Child-Pugh class A or B disease (HR 0.30, 95% CI 0.11 to 0.85) but not in those with cirrhosis and Child-Pugh class C disease (HR 1.04, 95% CI 0.45 to 2.37). Within the first 5 days, the portal-pressure gradient increased significantly in patients assigned to the liberal strategy (P = 0.03) but not in those assigned to the restrictive strategy.ConclusionsCompared with a liberal transfusion strategy, a restrictive strategy significantly improved outcomes in patients with acute UGIB.
