Objective: The impact of establishing a pulmonary embolism response team (PERT) in patients with pulmonary embolism (PE) has been proven in many developed countries. However, the efficacy of a PERT largely depends on expertise and infrastructure. This study explored the benefit of establishing a PERT in developing countries with limited healthcare resources by comparing the outcomes of patients with acute PE before and after PERT establishment at University Medical Center Ho Chi Minh City in Vietnam.
Methods: We conducted a single-center observational study from January 1, 2019, to August 1, 2021. All patients with PE confirmed on computed tomography were included. Patients admitted before PERT establishment were treated by cardiologists alone, while those hospitalized after PERT establishment were managed by the PERT.
Results: A total of 130 patients were included (pre-PERT estab-lishment: 51 patients; post-PERT establishment: 79 patients). The demographic characteristics, severity of PE, and clinical and laboratory findings were similar between the two groups. The post-PERT establishment group had a lower incidence rate of major and clinically relevant nonmajor bleeding (11.3% vs. 31.4%, p = 0.005) and required more interventional therapies (16.5% vs. 3.9%, p = 0.046) than did the pre-PERT establishment group. The in-hospital mortality rate decreased in the post-PERT establishment group compared with that in the pre-PERT establishment group (8.9% vs. 21.6%, p = 0.041).
Conclusions: Involvement of the PERT in PE management was associated with improved outcomes of patients with PE, including reduced bleeding and mortality rates in a resource-constrained hospital.
