Venous thromboembolic disease in the intensive care unit

Area of Science:

• Critical Care Medicine
• Vascular Medicine
• Hospital Medicine

Background:

• Critically ill patients exhibit heightened susceptibility to venous thromboemboli (VTE).
• Risk factors for VTE in the intensive care unit (ICU) include sedation and mechanical ventilation, alongside general population risks.
• The limited cardiopulmonary reserve in critically ill patients makes even small pulmonary emboli (PE) dangerous, underscoring the need for VTE prevention.

Purpose of the Study:

• To emphasize the critical importance of VTE prevention in critically ill patients.
• To highlight the significant reduction in VTE rates and associated complications through systematic prophylaxis.
• To advocate for immediate VTE risk assessment and thromboprophylaxis prescription upon ICU admission.

Main Methods:

• Review of existing literature on VTE risk factors and prophylaxis in critically ill patients.
• Analysis of the impact of VTE on patient outcomes, including morbidity, mortality, and hospital length of stay.
• Consideration of established guidelines, such as those from the American College of Chest Physicians (ACCP), for VTE prophylaxis.

Main Results:

• Without thromboprophylaxis, VTE incidence in the ICU can range from 15% to 60%.
• Systematic implementation of VTE prophylaxis demonstrably reduces VTE rates, morbidity, and mortality.
• Guidelines recommend routine VTE prophylaxis for all ICU patients.

Conclusions:

• All intensive care unit (ICU) patients require immediate evaluation for VTE risk upon admission.
• Appropriate thromboprophylaxis therapy should be prescribed without delay to prevent VTE.
• Proactive VTE prevention is essential for improving outcomes and reducing healthcare costs in critically ill populations.
