BackgroundA pulmonary embolism response team (PERT) is a multidisciplinary team established to improve clinical care for patients with pulmonary embolism (PE). However, data regarding detailed institutional experience and clinical outcomes from such teams are sparse.AimsWe aim to assess the frequency of activations, patients' characteristics, PE severity, applied treatments, and outcomes of PE patients treated by Polish PERTs.MethodsThe survey registry was conducted between June 2018 and July 2020. All consecutive PERT activations of four institutionalized PERTs in Poland were analyzed. Patients' characteristics, therapies applied, and in-hospital outcomes were evaluated.ResultsThere were 680 unique PERT activations. The majority of activations originated from emergency departments (44.9%), and the remaining originated from internal medicine/cardiology units (31.1%), surgery/orthopedics (9.1 %), oncology (6.3%), intensive care units (6.0%), and others (2.5%). The origin of activation varied significantly between institutions (P <0.01). Most PERT cases were patients with intermediate-high risk PE (42.9%), whereas high-risk PE occurred in 10% of patients. Anticoagulation alone was delivered to 80.3% patients, and 23.3% patients received at least one advanced therapy: catheter directed therapies (11.3%), systemic thrombolysis (5.3%), surgical embolectomy (2.4%), vena cava filter placement (3.7%), and extracorporeal membrane oxygenation (0.6%). In-hospital mortality in the whole study group was 5.1%, with significant differences between institutions (P = 0.01).ConclusionsThe frequency of PE severity, type of delivered catheter-directed treatment, and in-hospital mortality varies between institutions without significant discrepancies in PERT activations. This variation between expert centers highlights the local differences in PERTs' organizational and operational forms.
