Objective: This study examined whether the changes in reimbursement coverage of brain magnetic resonance image (MRI) affected practice for patients who visited the emergency department with dizziness as the chief complaint.
Methods: Among the 5,423 patients who visited the emergency department for dizziness in 2017, 2019, and 2021, 4,497 patients were included in the study retrospectively and investigated by brain diffusion-weighted MRI and the presence of cerebral infarction on brain diffusion-weighted MRI. This study examined whether there was a significant difference before and after the change.
Results: In 2017, 2019, and 2021, 1,489, 1,570, and 1,438 patients with dizziness visited the emergency department, respectively. The number of patients who underwent a brain MRI scan gradually increased from 237 (15.9%) in 2017 to 628 (40.0%) in 2019 and 948 (65.9%) in 2021 (P<0.001). The number of positive findings on brain MRI scan increased gradually from 30 patients (2.0%) in 2017 to 47 patients (3.0%) in 2019 and 53 patients (3.7%) in 2021 (P=0.025). The ratio of positive findings of brain MRI scans to the number of patients who underwent brain MRI scans decreased gradually to 12.7% in 2017, 7.5% in 2019, and 5.6% in 2021 (P=0.001).
Conclusion: The changes in the reimbursement coverage of brain MRI affect the number of brain MRI scans and the detection of cerebral infarction.
