The interaction of patients’ physical status and time to endoscopy on mortality risk in patients with upper gastrointestinal bleeding: A national prospective cohort study

BACKGROUND AND AIM:The correct time to perform an upper endoscopy is decisive in acutely GI bleeding patients. However, patients' physical status may affect mortality. We speculated that the physical status and procedural time could be the principal factors accountable for death-risk. The primary aim was to verify the interaction between physical status and time to endoscopy on mortality; the secondary aim was to verify the interaction of the physical status and time to endoscopy on the length of stay (LOS). METHODS:Consecutive patients admitted to 50 Italian hospitals were included. Clinical and endoscopic data were recorded. A multiple logistic regression analysis was performed and the interaction of adjusted clinical physical status and time to endoscopy on mortality was calculated. RESULTS:Complete data were available for 3.190 patients. The time frames did not interfere with outcomes but influenced LOS. Conversely, the ASA score correlated with mortality, LOS, need for transfusions and rebleeding risk. CONCLUSION:Endoscopy time should be tailored to the patient's physical. In our experience, ASA 1-2-3 patients can be safely submitted to endoscopy to reduce the LOS; on the contrary, keen attention should be paid to ASA4 patients, following the 'not too early-not too late' rule (12-24 h from admission).
