The aim of the study is to evaluate the impact of the schedule (day or night) and the day of admission (working or weekend / night) on the mortality of patients with non-varicose upper gastrointestinal bleeding after performing an early gastroscopy.~A retrospective observational study will be carried out in patients admitted to the bleeding unit of the Santa Creu I Sant Pau Hospital, where we observed hospital mortality and 30 days after performing an early gastroscopy, the duration of admission, signs of hemorrhagic activity in a period of less than 12 h. After early gastroscopy and types of endoscopic treatments, data will be collected by reviewing medical records.~The number of patients expected to be included in this study is 1320 patients. Patients will be included the day they enter the bleeding unit for an early gastroscopy.
The hypothesis is that the mortality of patients with non-varicose upper gastrointestinal bleeding after performing early gastroscopy who are admitted on weekends and night hours is higher than those admitted on weekdays or during daytime hours.
