Home treatment in pulmonary embolism

Area of Science:

• Cardiology
• Pulmonary Medicine
• Clinical Trials

Background:

• Limited data exists on outpatient care feasibility for acute pulmonary embolism (PE).
• Assessing early discharge versus standard hospitalization for acute PE is crucial for patient management.
• Identifying low-risk PE patients is key for safe early discharge protocols.

Purpose of the Study:

• To compare the efficacy and safety of early discharge versus standard hospitalization in acute symptomatic PE patients.
• To evaluate venous thromboembolic recurrences, bleeding rates, and mortality in acute PE management strategies.
• To assess the accuracy of clinical prediction rules in identifying low-risk PE patients for outpatient management.

Main Methods:

• A multicenter randomized clinical trial involving 132 low-risk acute symptomatic PE patients.
• Patients were randomized to either early discharge (n=72) or standard hospitalization (n=60).
• Follow-up for three months included monitoring for venous thromboembolic recurrences, bleeding, and mortality.

Main Results:

• Overall mortality was 4.2% in the early discharge group and 8.3% in the standard hospitalization group.
• Non-fatal recurrences were 2.8% (early discharge) and 3.3% (standard hospitalization).
• Clinically relevant bleeding rates were 5.5% (early discharge) and 5% (standard hospitalization); short-term mortality was 2.8% in the early discharge group versus 0% in the standard hospitalization group, leading to study suspension.

Conclusions:

• Complication rates did not significantly differ between early discharge and standard hospitalization for acute PE.
• An unexpectedly high rate of short-term mortality was observed in a low-risk PE patient group.
• Clinical prediction scores for acute PE require validation in well-designed clinical trials to ensure patient safety.
