Inhospital and delayed mortality after upper gastrointestinal bleeding: an analysis of risk factors in a prospective series

Abstract

Background: Detailed analyses of mortality after upper gastrointestinal (GI) bleeding are lacking. Follow-up rarely extends beyond 30 days.

Aims: Our aim was to analyze in-hospital and delayed 6-months mortality, identifying risk factors.

Methods: This was a prospective study on patients with upper GI bleeding over 36 months. Clinical outcomes were in-hospital and delayed-6 month-mortality.

Results: Four hundred and forty-none patients were included. Overall inpatient mortality was 9.8% but mortality directly related to bleeding was 5.1%. Patients who died presented lower systolic blood pressures, platelet recounts, prothrombin times and lower levels of hemoglobin, calcium, albumin, urea, creatinine and total proteins. Cirrhosis and neoplasms determined a higher in-hospital mortality. Albumin levels were protective, whereas creatinine and an active bleeding were risk factors for in-hospital death in multivariate analysis. Up to 12.6% of patients discharged died in the first 6 months. Neoplasms, chronic kidney disease, coronary disease and esophageal varices were related to delayed mortality. Coronary disease and neoplasms were independent risk factors for mortality, but albumin levels were protective in multivariate analysis.

Conclusion: Comorbidities were risk factors for delayed mortality, whereas albumin levels were a protective factor for in-hospital and delayed deaths. Six months mortality is proportionately as important as in-hospital mortality. Half of the delayed deaths might be preventable.
