Abstract

Background

Interhospital transfer (IHT) for acute pulmonary embolism (PE) is increasingly performed to improve access to advanced reperfusion therapies. It is unclear if outcomes of patients undergoing IHT are comparable with those of patients presenting in-house to hospitals with PE Response Team (PERT) capabilities.

Objectives

To determine whether outcomes of patients with acute PE undergoing IHT differ from those of patients presenting in-house.

Methods

We retrospectively reviewed 386 patients with acute PE who were treated by PERT at 1 of 3 urban teaching hospitals in the Mount Sinai Health System in New York City from January 2021 to October 2023. Propensity score–weighted analysis was performed to compare the outcomes of patients managed in-house with those of patients undergoing IHT.

Results

Two hundred eighty-four patients presented in-house, while 102 were transferred from other hospitals. Median PE Severity Index score was 84, and 3 (0.8%), 80 (20.7%), 237 (61.4%), and 66 (17.1%) had low-risk, intermediate low–risk, intermediate high–risk, and high-risk PE. Odds of receiving systemic thrombolysis (odds ratio [OR], 1.06; P = .06) or advanced therapies (OR, 0.95; P = .003) were not significantly different between the 2 groups. Rates of 30-day mortality, major bleeding, and readmission were 6.9%, 2.9%, and 9.8% for the IHT group and 10.6%, 2.1%, and 13% for the in-house group, respectively. IHT patients had lower odds of 30-day mortality (OR, 0.88; P = .003) and higher odds of major bleeding (OR, 1.03; P = .04).

Conclusion

PERT-guided IHT for patients with acute PE was associated with reduced mortality but increased risk of bleeding compared with patients managed in-house at hospitals with PERT capabilities.
