Περίληψη: Background: Headache is a common emergency department (ED) presentation. We aimed to determine the proportion of patients undergoing Computerised Tomography (CT) for non-traumatic headache and identify factors influencing clinician decision-making.
Methods: We conducted a retrospective chart review of adult ED presentations at the Royal Melbourne Hospital from January to March 2024. Clinical features and CT data were extracted and mapped against SNOOP4 features.
Results: Among 223 patients, 124 (55.6 %) underwent CT, with abnormal findings in 15.3 % (19/124). No patient-reported symptoms increased the likelihood of CT ordering; photophobia was negatively associated (Odds Ratio (OR)= 0.41, 95 % Confidence Interval (CI):0.22-0.79). Examination abnormalities in peripheral sensation (OR=13.04, 95 %CI:1.69-100.59) and strength (OR= 3.62, 95 %CI:1.00-13.09) increased CT use. Patients with > 2 SNOOP4 features had markedly higher odds of receiving CT (OR= 13.5, 95 %CI:3.12-58.34) and of abnormal findings (OR= 5.75, 95 %CI:2.03-16.27).
Conclusions: CT neuroimaging for non-traumatic headache was frequently performed, with a relatively low abnormal yield. While patient-reported symptoms did not influence CT ordering, examination findings and cumulative SNOOP4 features were associated with both imaging decisions and abnormal results. These findings support future studies into red-flag-based pathways to guide purposeful CT use.
