Key Points

To evaluate national trends, demographic factors, and hospital characteristics associated with head CT utilization in US emergency departments between 2007 and 2022.
Conducted a retrospective cohort analysis of the National Hospital Ambulatory Medical Care Survey (NHAMCS) database from 2007 to 2022.
Employed multivariable logistic regression with survey weights and interaction terms to examine the odds of head CT use across time, demographics, and hospital settings.
Total annual head CT examinations increased more than twofold from 7.8 million to 16 million between 2007 and 2022 (p < 0.001).
Patients aged 65 years or older had significantly higher odds of receiving a head CT compared with patients under 18 years (OR 6.24, 95% CI 5.66–6.88).
Head CT use was significantly lower among Black patients (OR 0.90, 95% CI 0.85–0.96), Medicaid beneficiaries (OR 0.82, 95% CI 0.77–0.87), and patients treated at rural hospitals (OR 0.76, 95% CI 0.70–0.83).
