Abstract
Background
Acute gastrointestinal bleeding (GIB) is a life-threatening event. Around 20-30% of patients with GIB will develop hemodynamic instability (HI).
Objectives
We aimed to quantify HI as a risk factor for the development of relevant end points in acute GIB.
Design
A systematic search was conducted in three medical databases in October 2021.
Data sources and methods
Studies of GIB patients detailing HI as a risk factor for the investigated outcomes were selected. For the overall results, pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated based on a random-effects model. Subgroups were formed based on the source of bleeding. The Quality of Prognostic Studies tool was used to assess the risk of bias.
Results
A total of 62 studies were eligible, and 39 were included in the quantitative synthesis. HI was found to be a risk factor for both in-hospital (OR: 5.48; CI: 3.99-7.52) and 30-day mortality (OR: 3.99; CI: 3.08-5.17) in upper GIB (UGIB). HI was also associated with higher in-hospital (OR: 3.68; CI: 2.24-6.05) and 30-day rebleeding rates (OR: 4.12; 1.83-9.31) among patients with UGIB. The need for surgery was also more frequent in hemodynamically compromised UGIB patients (OR: 3.65; CI: 2.84-4.68). In the case of in-hospital mortality, the risk of bias was high for 1 (4%), medium for 13 (48%), and low for 13 (48%) of the 27 included studies.
Conclusion
Hemodynamically compromised patients have increased odds of all relevant untoward end points in GIB. Therefore, to improve the outcomes, adequate emergency care is crucial in HI.
