Impact of Multidisciplinary Pulmonary Embolism Response Team Availability on Management and Outcomes

      Treatment strategies for complex patients with pulmonary embolism (PE) are often debated given patient heterogeneity, multitude of available treatment modalities, and lack of consensus guidelines. Although multidisciplinary Pulmonary Embolism Response Teams (PERT) are emerging to address this lack of consensus, their impact on patient outcomes is not entirely clear. This analysis was conducted to compare outcomes of all patients with PE before and after PERT availability. We analyzed all adult patients admitted with acute PE diagnosed on computed tomography scans in the 18 months before and after the institution of PERT at a large tertiary care hospital. Among 769 consecutive inpatients with PE, PERT era patients had lower rates of major or clinically relevant nonmajor bleeding (17.0% vs 8.3%, p = 0.002), shorter time-to-therapeutic anticoagulation (16.3 hour vs 12.6 hour, p = 0.009) and decreased use of inferior vena cava filters (22.2% vs 16.4%, p = 0.004). There was an increase in the use of thrombolytics/catheter-based strategies, however, this did not achieve statistical significance (p = 0.07). There was a significant decrease in 30-day/inpatient mortality (8.5% vs 4.7%, p = 0.03). These differences in outcomes were more pronounced in intermediate and high-risk patients (mortality 10.0% vs 5.3%, p = 0.02). The availability of multidisciplinary PERT was associated with improved outcomes including 30-day mortality. Patients with higher severity of PE seemed to derive most benefit from PERT availability.
