Abstract
Acute gastrointestinal bleeding cases, whether upper or lower, are considerably common medical emergencies, requiring accurate diagnosis to provide appropriate treatment for each patient and thus avoid longer hospitalization times and costs. In early 2022, Memorial Uningá Hospital positioned itself as a reference center for treating such patients originating from the 15th Health Regional of Maringá, allowing for a cross-sectional observational study using secondary data from electronic medical records. This work aims to gather such data and evaluate its impact on the hospital routine. During the study period, a total of 114 patients with a diagnosis of the disease were treated. The prevalence was 85.4 cases per 1000 admissions. Regarding deaths, 18 were recorded, with an average age of 74.8 years for these patients and occurring equally between sexes, resulting in a lethality rate of 157.8 per 1,000 cases. The most important risk factors that may be related to the evolution and occurrence of bleeding can be considered the use of nonsteroidal anti-inflammatory drugs (NSAIDs), anticoagulant use, smoking, and alcoholism. Thus, through this study, it was possible to conclude that, as found in current literature, gastrointestinal bleeding cases still present a high incidence in society today. The bleeding etiologies are variable and have changed in frequency over the years. Knowledge of these variations is essential for improving the management of these patients, allowing for the development of protocols aimed at minimizing failures in this type of care.
