Abstract
Background and Objectives: Pericardial effusion with tamponade may lead to hemodynamic compromise requiring rapid intervention. Cardiac point of care ultrasound (POCUS) has been shown to lead to earlier diagnosis and drainage of pericardial effusions at a single site. We hypothesized that POCUS performed by the emergency physician would decrease time to drainage across multiple sites.
Methods: This is a multicenter, retrospective cohort study of patients undergoing a procedure for drainage of non-traumatic pericardial effusion after admission from the ED between 7/1/2012 and 6/30/2020. Preliminary data from five sites are reported. Patients undergoing a pericardial drainage procedure were identified using billing codes. The primary exposure was the utilization of POCUS in the ED. The primary outcome was time to drainage of pericardial effusion. Data was abstracted from the EHR using single examiner physician chart review. Univariate median time to drainage was estimated using the Kaplan-Meier method. Multivariable Cox regression was used to determine the association between POCUS and time to drainage.
Results: 805 encounters were included in this preliminary analysis and 402 (49.9%) underwent POCUS. POCUS patients were more likely to have a pericardial effusion diagnosed in the ED (90.8% vs. 47.1%, p?
Conclusion: POCUS was associated with decreased time to drainage for non-traumatic pericardial effusion. POCUS patients were found to have a higher rate of tamponade, yet a higher rate of discharge by HD 7 compared to patients that did not undergo POCUS and lower rates of UIT and RRT utilization. These findings suggest that emergency physician performed POCUS can decrease time to intervention and adverse events during hospitalization for patients with pericardial effusion.
