Objective This study aims to understand the demographics and healthcare costs for patients presenting to the emergency department (ED) with transient ischemic attack (TIA).

Background

TIA is characterized by sudden onset of focal neurological symptoms, followed by complete resolution. A TIA occurrence is strongly associated with subsequent stroke, along with possible morbidity and mortality.

Design/Methods We performed a retrospective, quantitative study utilizing the Healthcare Cost and Utilization Project, Nationwide Emergency Department Sample (HCUP-NEDS) datasets from 2016 to 2020. ED visits in adult patients with the ICD-10 billing code related to TIA were analyzed. Multiple patient-level variables from the HCUP core datasets were utilized, including age, sex, median household income of residing zip code, patient disposition, and cost of care.

Results Between 2016 and 2020, 1,506,538 patients were reported with TIA. Patients on average were 70 ± 14.46 years old, and females comprised 56% (n=836,357) of the population. Over the five years, 450,855 (30%) TIA patients were from the lowest income group, and the highest income group consistently had the fewest TIA cases (n=290,027, 19%). The average charge for ED services rose by more than 55%, from $9,303 in 2016 to $14,503 in 2020. Patients discharged home with a TIA diagnosis from the ED peaked in 2019 with 150,746 (10%) patients and decreased to 141,370 (9%) in 2020. Admission rates to the hospital decreased from 131,545 (9%) in 2016 to 101,945 in 2020 (7%). Trends of increasing routine discharges and decreasing inpatient admissions may be related to broader factors like hospital capacity or external events (e.g., COVID-19 pandemic).

Conclusions More patients from low-income backgrounds presented with TIA, which was associated with rising healthcare costs. This emphasizes the importance of continued monitoring and resource allocation, particularly for lower-income populations.
