Analysis of patients with upper gastrointestinal bleeding: a study from Anatolian, Turkey Seasonal Distribution of Gastrointestinal Bleeding

Abstract

The aim of our study was to analyze if we have a seasonal or circadian distribution of acute upper gastrointestinal bleeding (AUGIB) patients, and to evaluate the laboratory and demographic risk factors on mortality rates. We scanned all of the files of the patients who had been diagnosed with AUGIB, for a ten year period. Datas' about seasonal distribution, circadian rhythm, admission hemoglobin, blood urea nitrogen and demographic variables were extracted from the charts. We didn't observed a seasonal distribution for AUGIB inspite of we excluded the drug effect by analyzing its seasonal distribution. Also our patients were admitted mostly nights which was compatible with the literature. Whereas our admission rate between 24 and 06 hour period was low. Admission low hemoglobin level, impaired blood urea nitrogen and creatinine level, and patients with advanced age has a higher mortality rate (p=0.03, p=0.003, p=0.02, p=0.001 respectively). Climatic factors effect on the seasonal distribution among AUGIB patients is not observed. Other risk factors (mental-physical) should also be evaluated. Low hemoglobin level, impaired renal functions and advanced age are bad risk factors for prognosis.
