Factors associated with severity and length of hospital stay in patients with acute upper gastrointestinal bleeding: insights from two Ethiopian hospitals

Background Upper gastrointestinal bleeding (UGIB) is a critical emergency with substantial morbidity and mortality. Outcomes depend on bleeding severity, patient risk factors, and comorbidities. This study evaluated clinical patterns and factors influencing disease severity and hospital stay among patients present with UGIB symptoms at two major Ethiopian hospitals. MethodsA retrospective, cross-sectional review was conducted on 199 UGIB patients admitted to Yekatit 12 Hospital Medical College (Y12HMC) and Tikur Anbesa Specialized Hospital (TASH) from September 2022 to September 2023. Data on demographics, clinical presentations, endoscopic findings, and outcomes were analyzed using SPSS version 26. Binary logistic regression assessed associations, with statistical significance set at P < 0.05. ResultsOf 199 patients, 70.9% were male, predominantly aged 18-40. Hematemesis (63.8%) and hematemesis with melena (27.6%) were common presentations. Endoscopy was not performed on more than half of the participants, with 116 patients (58.3%) not undergoing this procedure. Among the 83 cases who did have endoscopy, esophageal varices emerged as the most common condition, observed in 43.3% (36 cases. Smoking (AOR = 1.77), alcohol intake (AOR = 1.89), and drug use (AOR = 1.34) were linked to higher severity scores. Alcohol use, comorbidities, liver disease, and previous drug use correlated with prolonged hospital stays. ConclusionUGIB predominantly affects younger males, with hematemesis as the primary presentation. Key factors like smoking, alcohol intake, and drug use were associated with greater disease severity and longer hospital stays. These findings suggest the importance of lifestyle interventions, particularly in resource-limited settings.
