Abstract

Introduction: Computed tomography (CT) is routinely used in the emergency department (ED) due to its ease of access and its ability to rapidly rule in or out many serious conditions. Freestanding emergency departments (FSEDs) have become increasingly used as an alternative to hospital-based emergency departments (HBEDs). The objective of this study was to investigate if the utilization rate of CT differs between FSEDs and HBEDs for chest pain.

Methods: A retrospective evaluation of patients presenting to 17 EDs within a large integrated healthcare system between May 1, 2019 - April 30, 2021 with a chief complaint chest pain. Categorical variables are presented as frequencies and percentages. Continuous variables are presented as mean and standard deviation. Multiple logistic regression was used to assess the effect of facility on CT utilization for chest pain.

Results: There were 67,084 patient encounters included in the study. Patients were predominately female (55%), white (61%), and insured through Medicare/Medicaid (59%). After controlling for predictive variables which included Charlson Comorbidity Index, ESI, age, sex, and race, patients who presented to FSEDs with chest pain were less likely to have a CT than those who presented to a HBED (AOR = 0.85, CI (0.81-0.90).

Conclusion: CT scans of the chest are utilized less frequently at FSEDs compared to HBEDs for patient presenting with chest pain.
