MORALES URIBE, C. H. et al. Upper gastrointestinal bleeding: risk factors for mortality in two urban centers in Latin America. Rev. esp. enferm. dig. [online]. 2011, vol.103, n.1, pp.20-24. ISSN 1130-0108.

Objective: to describe the experience with upper gastrointestinal bleeding (UGIB) in two major Latin American hospitals; its main cuses, treatment and prognosis, while exploring some risk factors associated with death. Design: prospective cohort study. Patients and methods: We included 464 patients older than 15 years of age from two reference centers. We studied some demographic variables, history, clinical presentation, treatment and mortality. We explored the association betwen those variables and death. Results: The mean age was 57.9 years, and the male: female ratio was 1.4:1. Three hundred and fifty nine patients (77.4%) were seen for gastrointestinal bleeding (outpatients bleeding) and 105 patients (22.6%) were inpatients seen for UGIB. A total of 71.6% of patients admitted with the diagnosis of upper GI bleeding underwent upper GI emdoscopy (EGD) within 24 hours. The main causes of bleeding were peptic ulcer (190 patients, 40.9%), erosive disease (162 patients, 34.9%) and variceal bleeding (47 patients, 10.1%). Forty four patients died (9.5%). Patient who presented with bleeding due to other causes during hospitalization has a higher mortality risk than those whose complaints were related to gastrointestinal bleeding (RR 2.4, 95% CI 1.2-4.6). An increasing number of comorbidities such as those described in the Rockall Score, were also associated with a higher risk of mortality (RR 2.5 95% CI 1.1-5.4). Conclusion: Intrahospital upper GI bleeding and the presence of comorbilities ares risk factors for a fatal outcome. Identifying patients with a higher risk would help improve the management of patients with UGIB.
