• W2026126475 abstract "Introduction: The utility of the bleeding units has been well evaluated in upper gastrointestinal bleeding. The benefit of theses units are not well established on the management of lower gastrointestinal bleeding (LGB). Aims & Methods: Aim: To analyze the influence of the creation of a bleeding unit on the management of LGB. Design: cohort study. Setting: tertiary teaching hospital. Patients: all consecutive patients admitted with LGB during 2004 (before the bleeding unit creation -group 1-) and during 2005 (after the bleeding unit creation -group 2-). Analysis: Group 1 and 2 were compared with respect to diagnostic accuracy, chance of offering endoscopic therapy and length of stay by univariate and multivariate analysis (Cox regression or logistic regression as required) adjusting for age, comorbidity, and severity of the bleeding episode. Results: During the period from 2004 to 2005, two hundred eighty eight patients with LGB were admitted, 119 during 2004 (before the creation of the bleeding unit, group 1) and 169 during 2005 (after the creation of the bleeding unit, group 2). A definitive source of bleeding was found in 20.16% (24/119) of the patients in group 1 and in 50.88% (86/169) of the patients in group 2 (p < 0.001). In addition, 7.5% of patients (9/119) received endoscopic treatment in group 1 and 15.69% of patients (27/169) in group 2 (p < 0.05). Finally, the hospital length of stay was significantly longer in group 1 (8.7 ± 8.0 days) than in group 2 (4.6 ± 4.6 days) (p < 0.001). In the multivariate analysis, management by the bleeding unit was independently associated with better chance of identifying a definitive source of bleeding (hazard ratio 3.93; 95% CI, 2.27-6.80; p < 0.001) and receiving endoscopic therapy (hazard ratio 0.35; 95% CI, 0.15-0.80; p = 0.03) and with shorter hospital stay (hazard ratio 2.04; 95% CI, 1.60-2.73; p < 0.001). Concerning severity of bleeding, the benefit of the bleeding unit on hospital stay was more patent in patients with non severe LGB (8.16 ± 8.79 days vs. 3.73 ± 2.94; p < 0.001) than in those with severe LGB (9.59 ± 6.4 days vs. 7.23 ± 6.98 days; p = 0.81). Conclusion: The implementation of bleeding units improves the management of the LGB with regard to superior diagnostic accuracy, increase in the chance to receiving endoscopic therapy and reduction in the hospital stay. This benefit is more patent in less severe bleeding episodes." @default.
