Overview

Pulmonary embolism response teams (PERTs) are being increasingly used for the management of patients admitted with acute pulmonary embolism (PE) and are endorsed by societal guidelines. Whether PERT improves outcomes remains unknown. The objective of this meta-analysis was to compare the outcomes of patients with acute PE treated by a PERT versus no PERT. A systematic review and study level meta-analysis was conducted by searching PubMed and EMBASE databases from inception until November 10, 2024 and included studies evaluating efficacy of PERT vs no PERT in patients admitted for acute PE. Outcomes included all-cause mortality (in-hospital and 30-day mortality), major and clinically relevant bleeding, advanced therapies utilization, length of stay (LOS), and 30-day readmission. Twenty-four retrospective observational studies met the inclusion criteria, comprising 15,809 patients (mean age 61.6 years with 49% male) with acute PE of which 6228 were treated with a PERT and 9,581 without a PERT. Lower all-cause mortality (in-hospital or 30-day mortality) (odds ratio [OR] = 0.72; 95% CI: 0.56 to 0.93; 24 studies), major or clinically relevant bleeding (OR = 0.60; 95% CI: 0.42 to 0.86; 15 studies), higher utilization of advanced therapies (OR = 3.16; 95% CI: 1.81 to 5.49; 19 studies), and lower hospital LOS (MD = −1.49; 95% CI: −2.59 to −0.39; 14 studies) were seen in the patients treated by a PERT compared to those not treated by a PERT. In this large meta-analysis of observational studies comparing outcomes in patients treated by PERT versus not treated by PERT, there were significantly lower short-term mortality, lower major or clinically relevant bleeding, higher utilization of advanced therapies and lower hospital length of stay with the existence of PERT. PERT should be the standard of care for the management of patients with acute PE.
