Venous thromboprophylaxis in gastrointestinal bleeding.

Area of Science:

• Internal Medicine
• Cardiology
• Gastroenterology

Background:

• Acute gastrointestinal (GI) bleeding poses significant risks to patients.
• Venous thromboembolism (VTE) is a potential complication in hospitalized patients.
• Optimal VTE prophylaxis strategies in GI bleeding patients require further investigation.

Purpose of the Study:

• To evaluate the utilization of VTE prophylaxis in patients with acute GI bleeding.
• To determine the incidence of thrombotic events in this patient population.
• To assess the impact of VTE prophylaxis on thrombotic event rates.

Main Methods:

• Retrospective study of 504 patients admitted with endoscopically confirmed GI bleeding over two years.
• Data collected on patient comorbidities, pre-hospitalization anticoagulation/antiplatelet use, VTE prophylaxis type, and duration.
• Primary endpoint: VTE development (deep vein thrombosis or pulmonary embolism) within one year.

Main Results:

• 20 VTE events (4%) occurred among 504 patients; in-hospital mortality was 4.6%.
• 8.5% incidence of thrombosis in patients with significant VTE risk factors versus 1.8% without (P=0.0009).
• No significant difference in thrombotic events between patients receiving pharmacological prophylaxis (1.2%) and those not receiving it (2.8%) (P=0.4).

Conclusions:

• VTE prophylaxis did not significantly alter the occurrence of thrombotic events in patients hospitalized for acute GI bleeding.
• Patient-specific risk factors, rather than routine prophylaxis, appear more critical in predicting thrombotic events.
• Further research may be needed to refine VTE prophylaxis guidelines for GI bleed patients.
